Abstract

The invention discloses a dehumidifier, including a bottom plate, a box body, a front board, an air filter, a back board, a blower, a heat exchanger, a compressor, an orifice, a motor stent, a condensate plate, a baffle and a water tank. The diameters of a screw hole which is arranged on a fixing hole on the lower part of the back board and is used for accommodating a screw and a nut and a groove are respectively 6.5mm and 12mm. Stress can be produced along the up-to-down direction of the back board if the fixing hole on the lower part of the back board is in too close contact with the screw. The dehumidifier provided by the invention can avoid the stress by enlarging the clearance between the fixing hole on the lower part of the backboard and the screw. Therefore, even if the product is subjected to the impact from outside, the impact can be buffered. And the fracture phenomenon appearing on the lower part of the backboard can be avoided, which makes the quality of the product improved.

Description

A kind of dehumidifier

Technical field

The present invention relates to a kind of dehumidifier that can remove indoor moisture.

Background technology

In general, dehumidifier is a kind ofly indoor malaria can be sucked its box house, and by have the condenser of refrigerant and heat exchanger that evaporimeter constitutes to reduce after the humidity by inner stream again to indoor discharge, thereby reduce the device of indoor air humidity.Fig. 1 is the dehumidifier STRUCTURE DECOMPOSITION stereogram of prior art.Fig. 2 is a backplate structural representation on the dehumidifier among Fig. 1.Fig. 3 is the fixing hole and the screw bonding state partial sectional view of the backplate bottom shown in Fig. 2.As Fig. 1～shown in Figure 3, the dehumidifier of this prior art mainly comprises: the chassis 51 that constitutes the bottom surface external structure; Constitute the casing 54 of end face and two lateral outer structures; Constitute the front upper external structure, and the front end face bottom is formed with air inlet 70, and top is equipped with the front panel 58 of operating portion and display part; Be positioned at the back side of front panel 58, be used for the air cleaner 52 of the impurity that the filtering inhaled air is mingled with; Constitute back side external structure, middle part is equipped with the backplate 55 of air discharge grille 53 on it; Be arranged on the rear end, inside of casing 54, constitute, be used for the pressure fan 74 of forced circulation room air by motor 75 and blowing fan 12; Be arranged on the interior forward end of casing 54, constitute, be used for carrying out the heat exchanger 60 of heat exchange with room air by evaporimeter 62 and condenser 63; Be arranged on the rear portion on chassis 51, be used for the refrigerant that circulates at evaporimeter 62 and condenser 63 is carried out compressor for compressing 66; Be arranged between pressure fan 74 and the heat exchanger 60, be formed with the orifice plate 68 that is used to guide the mobile circular hole 77 of air on it; Can be combined on circular hole 77 edges of orifice plate 68, be used to support the electric machine support 72 of pressure fan 74; Be horizontally set on the below of heat exchanger 60, be used to collect condensed water, and be formed with the condense water disk 90 of the draining that can discharge condensed water on it from heat exchanger 60 surface drippages; Be vertically set on the downside of condense water disk 90, and integrally formed, be used to separate the baffle plate 91 that compressor 66 and tank 80 are provided with the space with condense water disk 90; With the below that is positioned at condense water disk 90, the top is provided with the inlet opening 17 that is connected with osculum on the condense water disk 90, and the condensed water of the autocondensation water pond 90 that is used to collect forms the tank 80 of dehumidifier front lower structure simultaneously.But there is following point in the dehumidifier of this prior art: when assembling need utilize screw 81 to run through during dehumidifier to be positioned at the method for two fixing holes 82 of backplate 55 bottoms itself and chassis 51 are together with each other.The combined influence of factors such as suspension chassis 51 flatness, casing 54 bendings, above-mentioned two fixing holes 82 are difficult to alignment, and be used on this hole hold that screw rod 83 and the screw 85 of nut 84 and the diameter of groove 86 are respectively 4.5mm and 10mm on the screw 81, thereby with screw 81 on the size of corresponding site very close, so when product transports under cryogenic conditions, the bottom of backplate 55 begins produce fracture because of being subjected to external impact from the edge of fixing hole 82 with regard to being easy to, so not only can influence the outward appearance and the quality of product, but also can cause the rising of production cost.

Summary of the invention

In order to address the above problem, to the object of the present invention is to provide and a kind ofly can slow down impulsive force, thereby can prevent that the dehumidifier of fracture from appearring in the backplate bottom.

In order to achieve the above object, dehumidifier provided by the invention comprises the chassis that constitutes the bottom surface external structure; Constitute the casing of end face and two lateral outer structures; Constitute the front upper structure, the bottom is formed with air inlet, and top is equipped with the front panel of operating portion and display part; Constitute back side external structure, middle part is equipped with the backplate of air discharge grille on it; Be positioned at the back side of front panel, be used for the air cleaner of the impurity that the filtering inhaled air is mingled with; Be arranged on the rear end, inside of casing, constitute, be used for the pressure fan of forced circulation room air by motor and blowing fan; Be arranged on the interior forward end of casing, constitute, be used for carrying out the heat exchanger of heat exchange with room air by evaporimeter and condenser; Be arranged on the rear portion on chassis, be used for the refrigerant that circulates at evaporimeter and condenser is carried out compressor for compressing; Be arranged between pressure fan and the heat exchanger, be formed with the orifice plate that is used to guide the mobile circular hole of air on it; Can be combined on the circular hole edge of orifice plate, be used to support the electric machine support of pressure fan; Be horizontally set on the below of heat exchanger, be used to collect condensed water, and be formed with the condense water disk of the osculum that can discharge condensed water on it from the heat-exchanger surface drippage; Be vertically set on the downside of condense water disk, and integrally formed, be used to separate the baffle plate that compressor and tank are provided with the space with condense water disk; With the below that is positioned at condense water disk, the top is provided with the inlet opening that is connected with osculum on the condense water disk, and the condensed water of the autocondensation water pond that is used to collect forms the tank of dehumidifier front lower structure simultaneously; Be used to hold that screw rod and the screw of nut and the diameter of groove are respectively 6.5mm and 12mm on the screw on the described fixing hole that is positioned at the backplate bottom.

Dehumidifier provided by the invention is that the method that utilize to strengthen gap between the fixing hole of backplate bottom and screw prevents from too closely to cause the stress that occurs along the vertical direction on the backplate because of both contact positions, even this product is subjected to outside impact and also can cushions like this, therefore can prevent that phenomenon of rupture from appearring in the backplate bottom, thereby can improve the quality of product.
