[24] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
[25] Figure 3 is an exploded perspective view showing a dehumidifier according to the present invention, Figure 4 is an exploded perspective view showing a heat exchanger fixing structure of the dehumidifier according to the present invention.
[26] As shown in FIG. 3, the dehumidifier according to the present invention is installed at a cabinet 52 having a suction port and a discharge port 52h, and installed at a discharge port 52h side of the cabinet 52 to be indoors inside the cabinet 52. A heat exchanger (54) which sucks air and an evaporator (62) and a condenser (64) installed at the suction port side of the cabinet (52) and dehumidifying from the air blown into the cabinet (52) ( 60, an orifice 55 installed between the blower 54 and the heat exchanger 60 to guide air passing through the heat exchanger 60 to the blower 54, and the evaporator 62. A compressor (not shown) installed to connect the condenser 64 and compressing the refrigerant, and installed below the heat exchanger 60 to condense on the surface of the heat exchanger 60 when the heat exchanger 60 is dehumidified. A drain pan 68 through which condensed water flows down and a lower part of the drain pan 68. The drain pan 68 is partitioned so as to be detachably installed in the tank 66 to collect the condensate water flowing down from the heat exchanger 60, the portion in which the compressor is installed and the portion in which the water tank 66 is installed. It is configured to include a barrier (69) provided below.
[27] Here, the cabinet 52 has a cabinet body 52a having a front surface and a bottom surface open and a suction port formed at a rear side thereof, and a barrier installed at the bottom surface of the cabinet body 52a to install a compressor and a water tank 66. A base fan 52b formed integrally with the 69 and a discharge hole 52h are formed at both sides of the cabinet body 52a and coupled to the front surface of the cabinet main body 52a. It consists of the front panel 52c in which 52c 'was formed.
[28] In addition, the blower 54 is installed at the front of the orifice 55 to form a hole communicating with the discharge port 52h on both sides and the fan housing 54a having the rear open, and inside the fan housing 54a. It is composed of a fixed motor 54b, a blower fan 54c connected to the motor 54b and rotationally driven, and the evaporator 62 and the condenser 64 are refrigerant pipes 62a and 64a through which refrigerant is circulated. And first and second tube sheets 62b, 62c, 64b, and 64c supporting both side ends of the refrigerant pipes 62a and 64a.
[29] Particularly, the orifice 55 has a box shape in which the rear and bottom surfaces are open, and holes are formed in the front center to guide air so that turbulence does not occur toward the blowing fan 54c. A plurality of guide ribs 72 are installed to be installed as a plurality of guide ribs 72, and a plurality of guide ribs 72 are installed on the inner front surface of the orifice 55 at predetermined left and right intervals.
[30] Here, the guide ribs 72 are integrally formed or assembled to protrude rearward from the inner rear surface of the orifice 55 as shown in FIG. 4, and are installed at the rear end of the guide ribs 72. Fixing grooves 72a and 72b are formed in the grooves, respectively.
[31] In addition, the condenser 64 is formed such that the fixing projections 65a and 65b protrude at positions corresponding to the fixing grooves 72a and 72b at the ends of the first and second tube sheets 64b and 64c, respectively. do.
[32] Of course, the fixing protrusions 65a and 65b and the fixing grooves 72a and 72b may be formed in various shapes such as a square pillar or a cylindrical shape.
[33] On the other hand, the drain pan 68 has a plurality of support grooves on the upper end to support both lower ends of the refrigerant pipes 62a and 64a of the evaporator 62 and the condenser 64 so that a small capacity or a large capacity heat exchanger may be selectively installed. The end plate 74 in which 74a) is formed is provided to be variable left and right.
[34] Of course, support grooves 68b are formed on both side surfaces of the drain pan 68 so as to support the evaporator 62 and the condenser 64.
[35] In detail, the lower end of the end plate 74 is slidably mounted in a mounting hole 68a formed by cutting a straight line from a rear end of the drain pan 68 so that the end plate 74 may be installed in the drain pan 68.
[36] In this case, the mounting hole 68a is formed to be cut in advance in manufacturing the drain pan 68 so that the user can selectively cut.
[37] That is, first and second guide protrusions 74b and 74c are formed at the lower end of the end plate 74 so as to be engaged with the upper and lower sides of the mounting hole 68a.
[38] Looking at the fixing structure of the heat exchanger of the present invention configured as described above are as follows.
[39] First, a plurality of guide ribs 72 are installed inside the orifice 55 and an end plate is provided in the mounting hole 68a at an appropriate position according to the size of the heat exchanger 60, that is, the evaporator 62 and the condenser 64. 74 is installed.
[40] Here, the end plate 74 is slidably mounted to the mounting hole 68a such that the first and second guide protrusions 74b and 74c formed at the lower end thereof are engaged with the upper and lower sides of the mounting hole 68a.
[41] Next, the evaporator 62 has a screw (S) assembled at the front end of the first and second tube sheets 62b and 62c of the evaporator to the rear end of the first and second tube sheets 64b and 64c of the condenser. 64 is a fixing projection (65a, 65b) formed at the front end of the first and second tube sheets (64b, 64c) of the condenser is fitted in the fixing grooves (72a, 72b) of the guide rib (72).
[42] In addition, the evaporator 62 and the condenser 64 support the end plate 74 at the lower end of the refrigerant pipes 62a and 64a protruding outside the first and second tube sheets 62b, 62c, 64b and 64c. It is supported so as to be supported by the groove (74a), or the support groove (68b) of the drain pan (68).
[43] Therefore, a small capacity or large capacity heat exchanger may be selectively installed depending on the product.
[44] Specifically, when a large-capacity heat exchanger is installed, the air blown through the heat exchanger 60 when the dehumidifier is operated is relatively blown by the blower fan 54c by the guide ribs 72 installed inside the orifice 55. Guided to the side.
[45] On the other hand, when a small capacity heat exchanger is installed, air blown through the heat exchanger 60 during operation of the dehumidifier is relatively blocked from the outside by the guide ribs 72 installed on the outside of the orifice 55.
[46] The heat exchanger fixing structure of the dehumidifier according to the present invention configured as described above has a plurality of guide ribs at which the tip of the heat exchanger is fixed to the inside of the orifice so that a small capacity or a large capacity heat exchanger may be selectively fixed to an orifice for guiding air to the blowing fan side. In addition, the end plate supporting both lower ends of the heat exchanger is installed in the drain pan variably so that the orifice of the dehumidifier can be used in common, and furthermore, it is easy to apply when developing a new product.
[47] In addition, when a large-capacity heat exchanger is installed, air passing through the heat exchanger is guided to the blower fan during operation of the dehumidifier by the guide rib installed in the inner side of the orifice, thereby increasing the blowing efficiency.
[48] In addition, when a small-capacity heat exchanger is installed, air passing through the heat exchanger is double-blocked with the outside during operation of the dehumidifier by a guide rib installed on an outer side of the orifice, thereby reducing heat loss.
