    METHOD AND EQUIPMENT FOR CONTROLLING THE SAUNA HEATER
    FÖRFARANDE OCH APPARAT FÖR STYRNING AV BASTUAGGREGAT
    TECHNICAL FIELD
    The invention relates to a method and apparatus for controlling a sauna stove.
    BACKGROUND
    This section describes background information useful to the reader without intending to acknowledge the state of the art described herein.
    High-performance floor-standing stoves usually have a separate control center outside the sauna. From this control center, the supply cable for the sauna heater and a cable with a sauna temperature sensor and an overheating protection are placed on the sauna wall near the roof.
    The sauna control center sets the desired sauna temperature and possible timings. The control center can be connected to a property monitoring system that adjusts the stove on bypassing the stove timing function. The sauna can also be controlled via a mobile device or via the Internet.
    Technically, the control of the stove on and the temperature of the sauna has been implemented by adjusting the power supply of the stove with contactors. The contactors switch the power supply to the heater when the heater turns on. When the sauna temperature reaches the set value, the contactors switch off.
    The contactor control is connected to the sauna overheating circuit so that in case of overheating the overheat circuit is cut off and the contactor control cuts off the power supply to the resistors.
    Most of the floor standing heaters are equipped with simple controls without remote access, ie the user must physically go to the control center to turn on the heater.

    SUMMARY
    It is an object of the invention to provide a new alternative for controlling the heater, for example to enable remote operation.
    According to a first aspect of the invention there is provided a method of controlling the operation of a sauna stove. The method is characterized in that the sauna heater is controlled by interrupting the heater's power supply by utilizing the temperature measurement of the sauna outside the control system of the sauna heater. The heater's power supply can be interrupted by the heater's overheating circuit. Alternatively or additionally, the power supply to the heater can be interrupted through the sauna's heat control circuit. The sauna heater controls the temperature of the sauna.
    Through the heater overheat protection circuit or sauna heat control circuit, the power supply to the heater can be interrupted by a controllable switch connected to the overheat protection circuit or sauna heat control circuit.
    The heater power supply can be controlled by a local control circuit which receives the sauna temperature information and performs said heater power supply control using the temperature information it receives.
    Sauna temperature information can be repeatedly sent to the remote control equipment. Remote control equipment can receive control information determined based on transmitted temperature information. The power supply to the heater can be controlled based on control data 25.
    According to a first aspect of the invention, there is provided apparatus for controlling the operation of a sauna stove. The apparatus may comprise a low-current circuit used to control the stove, such as an overheat protection circuit or a sauna thermal control circuit 30 capable of breaking a controllable switch. The apparatus may comprise a control circuitry for controlling the controlled switch. The control circuitry may comprise decision-making means for making control decisions on the operation of the heater. The control circuitry can receive

    BRIEF PRESENTATION OF THE PATTERNS
    The invention will now be described by way of example with reference to the accompanying Figure 1, which schematically shows a side view of an exemplary sauna.
    DETAILED EXPLANATION
    In the following description, like reference numerals refer to like parts or steps. It is to be noted that the figures shown are not to scale in their entirety, and that they serve primarily the purpose of illustrating embodiments of the invention.
    Figure 1 illustrates a sauna 100 having control circuitry 110,111 mounted to stove 130 alongside its own control. The control circuitry 110, 111 stores the measurement data describing the sauna conditions 30, such as temperatures at different times, and transmits it to the external control unit 120 of the stove 130 controlling the stove 130, e.g. via the Internet. The control circuit 110,111 has an outlet 112 for a stove 130
    20175857 prh 27-09-2017 to a controllable switch 1322 in the overheat protection circuit 132 or the sauna temperature sensor circuit, such as a relay, which disconnects that circuit 132 when the power supply to the stove 130 is to be disconnected. Namely, in some electric saunas, switching off the temperature sensor circuit used to control the temperature of the sauna will cause the stove 5 to be turned off, and switching off the overheat protection circuit should also control the stove. The control circuitry 110, 111 has an input 114 for receiving said measurement data from one or more sensors 140.
    The control circuitry 110, 111 may be housed in the same housing together with at least one sensor 140 that measures the conditions of the sauna 100. In addition, or optionally, sensors 140 may have inputs in control circuitry 110, 111 for receiving measurement data from sensors 140 located outside the housing. For example, the housing may be placed near the stove 130, or, for example, underneath benches 20 in a cool space, or alternatively at the height of the shoulders of saunas 15 sitting on the upper deck 20, for example.
    The sensor or sensors 140 measuring the conditions of the sauna 100 are added to the sauna 100 in addition to the temperature sensor or sensors included in the control system of the sauna heater 130. Due to the sensing of the heater 130 not belonging to its own control system 20, the control circuitry 110, 111 and the sensors 140 enabling it to operate can be removed even though the heater 130 is not normally used.
    The control circuitry 110, 111 may comprise a sensor unit 110. The sensor unit 110 may be disposed with sensors 140 that measure the conditions of the sauna 100. The control circuitry 110, 111 may comprise a control unit 111 implemented in connection with the sensor unit 110 or separate from the sensor unit 110. There may be a digital bus 113 for transmitting measurement data between the sensor unit 110 and the control unit 111. The control unit 111 may be located in the stove 130 in connection with the power supply unit, for example the same room or enclosure as the power supply unit. The control unit may comprise 30 communication units, such as a cellular network modem or a wireless LAN connection circuit for transmitting data over a WLAN. The sensor unit and the control unit may be housed in different housings.
    20175857 prh 27-09- 2017
    The control circuitry 110, 111 may comprise analog and / or digital electronics.
    The control circuitry 110,111 may comprise a processor, memory, and program code for executing the processor in memory such that the operation of the control circuitry 110,111 is at least partially programmable.
    The system of Figure 1 can control the temperature of the sauna 100 via the Internet, schedule the stove 130 for a desired period of time (assuming that the own power supply of the stove 130 is continuously on, or the desired period is on switching on the stove 130 itself) The system of Fig. 1 can provide different sauna temperature settings for remotely set timers, typically within the sauna temperature settings set for the stove 130's own control system.
    Alternatively or additionally, control circuitry 110, 111 can control the heater 130 without local control information from the control unit 120. In this case, the control circuitry 110, 111 may comprise a local user interface or provide, for example, a web server to make local control settings, for example, in a browser, using the control server's web server page. The local control settings may include, for example, on and off times for the stove 130, target temperatures for different switching periods, or a general target temperature for the sauna.
    By interrupting the power supply of the stove 130 via, for example, an overheating circuit 132 or a temperature measuring circuit, the sauna can be timed and adjusted.
    100 temperatures for each timer, regardless of other timers, which is currently not possible with a conventional continuous-burning stove 130.
    As an alternative to control via the overheat protection circuit 132 or the temperature measuring circuit, the control may be accomplished by controlling the additional contactors 42 mounted on the power supply 40 of the heater 130 or its own contactors via control circuit 110, 111.
    20175857 prh 27-09- 2017 Improper connection may present a fire hazard. In addition, direct contact with the contactors may cause product liability issues, such as uncertainty about the validity of the heater's warranty and who is responsible if the heater breaks down, especially if the breakdown causes a fire.
    Disconnecting the overheat protection circuit 132 or the temperature measurement circuit does not interfere with the construction of the stove 130 or interfere with the normal operation of the safety systems of the stove 130. When the relay in the overheat protection or temperature measurement circuit is controlled by 12 or 24 V and a low current, various risks 10 can be avoided. If the relay or its control is somehow damaged or not functioning, the normal overheating protection of the stove 130 will turn off the stove 130 unless the temperature control of the stove 130 itself prevents the sauna 100 from overheating even to the limit of the overheating protection. The control circuitry 110,111 of Figure 1 may be an addition to the pre-installed sauna stove 130 and the stove 130's own control system, which utilizes external temperature measurement provided in addition to the temperature measurement connected to the stove 130's own control system.
    Significant energy savings can be achieved with the control system of Fig. 1, since the heating period of the sauna 100, i.e. the heating period of the stove 130 and the temperature 20, can be more precisely targeted at a desired time.
    In indoor swimming pools and other long-term saunas, the sauna temperature can be adjusted based on the intensity of the sauna. In general, the sauna is light during the day and busy in the evening. The temperature of the sauna must be adjusted to 25 high, eg 100 degrees Celsius, in the evening rush hour, so that the steam in the evening does not stop. In this case, the half-empty sauna is hot during the day, consumes energy, and the sauna panels dry in constant heat. With the control according to the embodiment of Figure 1, the temperature of the sauna 100 can be adjusted, for example, so that the sauna 100 is 70 C during the day and 100 C in the evening. The annual energy savings achieved in this way are of great economic importance.
    A similar adjustment can be made in the apartment sauna where each one
    20175857 prh 27-09- 2017 The sauna shift can be set to the temperature desired by the sauna. The problem with a high-rise sauna is that some people want a damp sauna of 60-70 degrees Celsius and others a drier sauna of 90-100 degrees Celsius. Often, as a compromise, the temperature of the sauna is set around 80 degrees Celsius and the temperature is disputed. The lower temperature setting 5 saves energy especially when there are empty shifts between sauna shifts, which causes the sauna to be unnecessarily hot rather than temporarily lowering the sauna temperature.
    The control circuitry 110, 111 may also measure or receive other measurement variables related to the sauna 100 and 10 such as the parallel measurement of the sauna 100 temperature, the sauna 100 air humidity, the carbon dioxide content of the sauna air and the noise or volume in the sauna 100. The control circuitry 110,111 may transmit to the remote control apparatus 120 other measurement data that it has measured or received in addition to temperature.
    In addition to temperature, one or more other metering data, such as the relative humidity of the sauna 100, may be used as a basis for controlling the stove 130 of the sauna 100.
    The control circuitry 110,111 can store (e.g., buffering for an hour, day, or week) measurement data, which can be used to monitor bathing and subsequently determine whether or not there has been a sauna session.
    The invention can also be applied to the stove 130, the control of which is inside the stove 130, for example at its lower part. Here, instead of the overheating protection circuit 132 or the temperature measuring circuit, the power supply to the heater 130 can be cut based on external temperature measurement without having to disassemble the heater 130. In this embodiment, the control and safety system of the heater 130 is avoided.
    In practice, the control of the stove 130 can be implemented by providing the stove 130 with a sauna
    100 is set to a temperature that is not intended to be exceeded. Aggregators
    20175857 prh 27-09- 2017
    The controllable switch 42, 1322 connected to the supply 130, the temperature measuring circuit or the overheat protection circuit 132 shuts off the heating when the external control detects the temperature of the sauna 100 having reached the set value 110,111.
    The time constraints on the continuous operation of a typical apartment heater do not allow for free scheduling. In some countries, free scheduling is only allowed when the sauna is under constant surveillance, which, for example, is considered to be the situation when the swimming pool is staffed, regardless of the actual level of supervision.
    According to one embodiment of the invention, two independent temperature measurements are provided for the control of the stove 130, by comparing which control circuitry 110,111 monitors the condition and accuracy of the temperature measurements. Such continuous temperature monitoring and associated deviation reporting can provide more reliable temperature monitoring than a swim supervisor or service technician at the pool.
    Measurement data describing the conditions of the sauna 100 may also include the temperature of the ceiling of the sauna 100, whereby the sauna 100 is under multiple control. In addition, with the carbon dioxide content of the sauna 100 air and the noise level of the sauna 100, efforts should be made to ensure that the sauna 100 did not leave unconscious saunas, which would be manifested by increased carbon dioxide content and prolonged silence.
    The foregoing description provides non-limiting examples of some embodiments of the invention. However, it will be apparent to one skilled in the art that the invention is not limited to the particulars set forth, but that the invention may be practiced in other equivalent ways.
    Some features of the embodiments shown may be utilized without the use of other features. The foregoing description is to be construed as merely describing the principles of the invention and not limiting the invention. Thus, the scope of the invention is limited only by the appended claims.
