[0028] The present invention will be described in detail below with reference to the drawings and embodiments:
[0029] Figure 4 It is a schematic diagram of the exploded structure of the dehumidifier of the present invention; Figure 5 Is a schematic diagram of the installation position of the guide housing in the dehumidifier of the present invention; Image 6 It is a schematic diagram of the guide housing structure of the dehumidifier of the present invention; Figure 7 It is a plan view of the guide housing of the dehumidifier of the present invention.
[0030] Such as Figure 4 to Figure 7 As shown, in the guide housing structure of the dehumidifier of the present invention, the case 4 forms the appearance of the dehumidifier, contains and protects the various components of the dehumidifier; the evaporator is arranged on the side of the air suction port, and the refrigerant is in the evaporator when the dehumidifier is running Mid-vaporization absorbs heat, so the evaporator is in a low temperature state. When the moist air inhaled passes through the evaporator, the moisture in the air condenses into condensed water on the evaporator, and the condensed water collects and falls into the drain pan; the condenser and The evaporators are arranged side by side, located at the back of the evaporator according to the air flow direction. The condenser is at a high temperature when the dehumidifier is running. The air passing through the evaporator exchanges heat with the condenser when it flows through the condenser, so that the temperature of the condenser is reduced. At the same time, the temperature of the air rises; the water receiving pan 20 is arranged under the evaporator and the condenser to collect the condensed water, and a drain is set on the drain, and the condensed water enters the water tank 12 through the drain; The air is sucked in and discharged from the case, so that the air flows in the case 4 to complete the heat exchange with the evaporator and the condenser. The fan 40 in the present invention adopts a centrifugal fan structure. The centrifugal fan is surrounded by a guide shell 44 to make the air When the fan rotates along the axial direction of the centrifugal fan, it enters from the air suction port on the rear side of the chassis. The air flows through the evaporator and the condenser in turn, enters the centrifugal fan, and is thrown out by the blades along the tangential direction of the fan 40, in the guide housing 44 The air flows directionally under the guidance, and the outlet of the guiding housing 44 corresponds to the upper part of the dehumidifier, so the dehumidified air is discharged into the room through the air outlet 59 on the upper part of the dehumidifier; the water tank 12 is arranged in the lower part of the dehumidifier , Used to store condensed water, the water tank 12 and the chassis 1 are integrally formed, and the side wall of the water tank 12 is formed by extending the chassis 1 upward. The chassis 12 and the water tank 1 are injection molded of engineering plastics, so that the water tank and the chassis become an integral part, and there is no need to adjust the water tank and the chassis separately.
[0031] The guide housing 44 is provided with a plurality of support protrusions 60 on the side facing the front panel of the dehumidifier cabinet. The length of the support protrusions 60 is equal to the distance between the guide housing 44 and the inner wall of the front panel. The top ends of the support protrusions are in contact with the inner wall of the front panel. Support the front panel. The support protrusions are distributed on the guide shell in a distributed manner, and the external force received on the front panel can be more evenly distributed to the supporting surface formed by the support protrusions, so as to avoid excessive concentration of force on a certain position on the front panel and prevent Excessive deformation of the front panel.
[0032] The shape of the top end of the support protrusion 60 is matched with the inner wall of the front panel, so that the top end of the support protrusion is in full contact with the inner wall of the front panel, thereby ensuring that there is a large enough contact area between the support protrusion and the inner wall of the front panel, thereby reducing the support protrusion and the front panel The pressure at the place where the force is applied makes the supporting structure stronger.
[0033] The support protrusion and the guide housing are integrally formed, and can be processed into a cylindrical structure, which not only ensures the support strength and support area of the support protrusion, but also reduces the production cost.
[0034] The guide housing 44 is provided with a plurality of intersecting reinforcing ribs 61 distributed toward one side of the front panel. The reinforcing ribs 61 further improve the strength of the guide housing and prevent the guide housing itself from being excessively deformed along with the front panel. At the intersection point, the force bearing performance of the support structure is better, and the support protrusion or the guide shell is prevented from breaking.
[0035] The water tank 12 is located in the middle of the chassis 1, so that the entire dehumidifier can also maintain the balance of gravity distribution when working. On both sides of the water tank, the compressor 50, the drainage part and the power line box are respectively arranged, and the original The components are distributed on both sides of the water tank, making full use of the space in the case, so that the location of each component is planned uniformly. The compressor fixing part 51 is formed by injection molding on the chassis. The shape and screw hole position of the compressor fixing part 51 correspond to the bottom mounting surface of the compressor. The protruding ribs around the compressor fixing part 51 can limit the position of the compressor 50. Make the fixing of the compressor more stable and combine with the compressor through the compressor fixing part on the chassis.
[0036] The bottom surface of the water tank 12 adopts an inclined structure. The lowest part of the water tank can be located at a corner of the bottom of the water tank. A recessed water collecting groove is set on the corner of the water tank. The water collecting groove is the lowest inner surface of the water tank. Under the action of gravity, the condensed water in the water tank finally flows into the water collecting tank and flows out from the complete drain in the water collecting tank, so that the condensed water in the water tank can be conveniently and quickly discharged when the dehumidifier is not used. The complete drain port is closed by a rubber plug on the outside of the chassis. When it is not necessary to use the complete drain port to drain water, the water tank should be kept tight, and the rubber plug can be opened to drain. In order to guide the discharged water, the complete drain opening of the chassis is connected with the drain pipe, so the condensed water can be led to any position. One end of the drain pipe is fixed on the side of the outside of the dehumidifier chassis, and the drain pipe can be hung up when it is not necessary to drain water. A water tank outlet is provided on the side wall of the water tank, and a water pump connected to the water tank outlet is provided in the drainage part on one side of the water tank, and the condensed water in the water tank is discharged to the outside of the dehumidifier by the operation of the water pump. When the water pump is installed, the water inlet of the water pump can be lower than the height of the water outlet of the water tank, so that the condensate can flow from high to low under the action of gravity, so that the pump without self-priming function can be selected, which saves the cost of the water pump.
[0037] The drain port of the water pump is connected with a water pipe, and the water pipe guides the condensed water to the outside of the cabinet of the dehumidifier. The end of the water pipe protruding from the chassis is fixed on the side of the outside of the dehumidifier chassis. One end of the water pipe can be removed from the outer side wall of the case when draining, and the water pipe can be retracted and fixed when not in use, thereby making the drainage structure more compact .
[0038] Casters 56 are arranged on the four corners of the chassis of the dehumidifier to make the movement of the dehumidifier more convenient, so that the position of the dehumidifier can be changed according to the specific needs of the user.
[0039] A water level sensor can be set in the water tank. One way of draining is: when the water level sensor measures that the condensate in the water tank reaches the drain height, the control circuit makes the water pump run according to a preset length of time, and the water pump runs for a period of time to discharge part of the condensate water automatically Stop, this mode of operation is based on a fixed duration and has nothing to do with the actual displacement.
[0040] Another drainage control method of the water tank is: when the water level sensor measures the condensed water in the water tank to reach the drainage height, the control circuit makes the water pump run, and when the water level sensor measures the condensate water in the water tank drops to a safe height, the control circuit makes The water pump stops running. This mode of operation can more accurately control the water level in the water tank.
[0041] The control circuit is arranged inside the case 4 of the dehumidifier, and a sheet metal support frame 57 is arranged between the chassis 1 and the guide shell 44 of the fan. When the dehumidifier is assembled, the support frame 57 and the case 4 of the dehumidifier are in contact with each other, which improves the dehumidifier The strength of the whole machine, to avoid the damage of the chassis during transportation, the control box 58 containing the control circuit is fixed on the support frame, so that the control box and the injection molding of the dehumidifier are separated as a whole. Once the control circuit is short-circuited, it will not affect The other components, the water pump and the control circuit, and the dehumidifier adopt independent operation modes, and they do not interfere with each other, ensuring the stability of the dehumidifier operation.
[0042] In the guide housing structure of the dehumidifier of the present invention, a plurality of support protrusions are distributed on the side surface of the guide housing facing the front panel of the chassis. The length of the support protrusions matches the distance between the guide housing and the inner wall of the front panel. The supporting protrusions are in contact with the inner wall of the front panel and are against the front panel. The multi-point supporting protrusions form a relatively uniform support surface for the front panel, which supports the front panel. When the front panel is under external force, it supports The protrusions support the front panel and disperse the force on the front panel so that it cannot undergo major deformation, thereby improving the deformation resistance of the front panel, increasing the overall structural strength of the dehumidifier chassis, and avoiding bumps or bumps during transportation. The front panel is damaged due to collision. In addition, the chassis and the water tank are an integral structure, which can be made by injection molding of engineering plastics through a mold. The water tank is set in the middle of the chassis, and the side wall of the water tank is formed by extending upward from the chassis, and compression is distributed on both sides of the water tank. The integrated structure of the machine, the drainage part and the power cord box, the chassis and the water tank can simplify the production and installation steps. Only one mold is needed during production, so the production cost of the mold is saved, and there is no need to use multiple molds to produce different parts. The chassis and the water tank in the present invention uniformly use the same engineering plastic material, which also reduces the production cost of the product. In addition, since the molded compressor installation part, drain part and power cord box have been processed on the chassis, the assembly of components can be more planned, and the internal space in the dehumidifier case can be reasonably allocated and used to make space The structure is more tidy, which is convenient for future maintenance and replacement of parts.
