Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a condensate drainage structure for a dehumidifier. Background Technology

[0002] Dehumidifiers, commonly used devices for regulating ambient air humidity, work by condensing water vapor in the air into liquid water through an evaporator, which is then collected and discharged. Dehumidifiers typically have a water tank to collect the condensate produced by the evaporator. After the condensate forms on the evaporator surface, it drips down under gravity. Some droplets fall onto the inner wall of the water tank, while others fall onto the surface of the water that has already reached a certain height within the tank. Whether falling onto the inner wall or the surface, the droplets create a significant noise that can disturb the user's rest. Furthermore, water droplets can splash onto the inner walls of the water tank, and prolonged residue can lead to bacterial growth, affecting hygiene. Utility Model Content

[0005] The condensate drainage structure of the dehumidifier according to the embodiment of this utility model has at least the following beneficial effects:

[0006] After condensate forms on the evaporator surface, it flows through the drainage structure into the water receiving tank. The water in the receiving tank flows from the drain outlet located on the outer periphery of the upper end plate to the inner wall of the water tank to enter the water tank. Under the action of gravity and the guiding effect of the flow guide, the water flows downward to the inner bottom wall of the water tank or merges from the water surface in the water storage cavity, thereby avoiding water droplets falling from a height and producing a dripping sound, reducing operating noise, and preventing water droplets from splashing onto the inner wall of the water tank and causing bacterial growth.

[0007] In some embodiments of this utility model, the water tank includes a tank body and a cover. The tank body has an upward-opening cavity. The cover is detachably installed at the opening of the cavity to form the water storage cavity. The upper end plate and the annular surrounding plate are formed on the cover.

[0008] In some embodiments of this utility model, the upper surface of the upper end plate is recessed downward to form a guide channel that guides the water in the water receiving tank to the water outlet, and the depth of the guide channel gradually increases towards the water outlet.

[0009] In some embodiments of this utility model, the upper surface of the upper end plate is provided with a first inclined surface and a second inclined surface, the first inclined surface and the second inclined surface intersect to form the guide groove with a "V" shaped cross-section, and one end of the ridge line where the first inclined surface and the second inclined surface intersect is located directly above the upper end of the guide member.

[0010] In some embodiments of this utility model, the flow guide is a strip-shaped flow guide plate formed on the inner side wall of the water tank. The strip-shaped flow guide plate extends from top to bottom to the inner bottom wall of the water tank. The upper end of the side of the strip-shaped flow guide plate away from the inner side wall of the water tank is connected to a flow guide slope that is inclined towards the inner side wall of the water tank.

[0011] In some embodiments of this utility model, the width direction of the strip-shaped diversion plate is perpendicular to the inner wall of the water tank, and the width dimension of the strip-shaped diversion plate gradually increases from top to bottom.

[0012] In some embodiments of this utility model, the dehumidifying body has a working state and an idle state. When the dehumidifying body is in the idle state, the dehumidifying body is at least partially housed within the cavity; when the dehumidifying body is in the working state, the dehumidifying body is placed on the cover.

[0013] In some embodiments of this utility model, one of the upper end plate and the base of the dehumidifying body is provided with a positioning protrusion, and the other is provided with a positioning slot that cooperates with the positioning protrusion, so as to prevent the dehumidifying body from horizontally displacing or rotating relative to the cover.

[0014] In some embodiments of this utility model, the base of the dehumidifying body is provided with four support feet distributed at the four corners of the quadrilateral. The four support feet are mounted on the upper end plate to create a height space between the dehumidifying body and the upper end plate. The drainage structure is a drain bend located within the height space, and the outlet of the drain bend faces the water outlet.

[0029] See Figure 1 , Figure 2 and Figure 4 The present invention discloses a condensate drainage structure for a dehumidifier, comprising: a water tank 100, wherein the water tank 100 has a water storage cavity 101 inside, the water tank 100 has an upper end plate 121, and an annular surrounding plate 122 is provided on the outer periphery of the upper end plate 121, a water receiving groove is defined between the annular surrounding plate 122 and the upper end plate 121, and a water outlet 123 communicating with the water storage cavity 101 is provided on the outer periphery of the upper end plate 121; the dehumidifier main... The dehumidifying body 200 is located above the water tank 100. An evaporator is provided inside the dehumidifying body 200. The bottom of the dehumidifying body 200 is provided with a drainage structure 210 for transferring water droplets generated by the evaporator to the water receiving tank. The inner side wall of the water tank 100 is provided with a guide 300 extending along the height direction of the water tank 100. The upper end of the guide 300 points to the water outlet 123 to guide water to flow downward along the inner side wall of the water tank 100.

[0030] After condensate forms on the evaporator surface, it flows through the drainage structure 210 into the water receiving tank. The water in the water receiving tank flows from the drain outlet 123 located on the outer periphery of the upper end plate 121 to the inner wall of the water tank 100 to enter the water tank 100. Under the action of gravity and the guiding effect of the guide 300, the water flows downward to the inner bottom wall of the water tank 100 or merges from the water surface in the water storage cavity 101, thereby avoiding the dripping sound caused by water droplets falling from a height, reducing working noise, providing users with a quieter and more comfortable resting environment, and also preventing water droplets from splashing onto the inner periphery of the water tank 100 and causing bacterial growth.

[0031] See Figure 2 and Figure 4 In some embodiments of this utility model, the water tank 100 includes a tank body 110 and a cover 120. The tank body 110 has an upward-opening cavity, and the cover 120 is detachably installed in the opening of the cavity to form the water storage cavity 101. The upper end plate 121 and the annular surrounding plate 122 are formed on the cover 120. The dehumidifying body 200 can be separated from the top of the cover 120. When it is necessary to clean the tank body 110 and empty the water in the water storage cavity 101, simply remove the cover 120 from the tank body 110, and the water can be poured out from the opening of the cavity, making it very convenient to use. Of course, in other embodiments, a drain hole and a plug sealing the drain hole can also be provided at the bottom of the tank body 110; opening the plug can also drain the water.

[0032] In addition, the faceplate 120 and the opening of the cavity can be connected by a snap-fit, magnetic connection, or plug-in method, which will not be specifically described or limited here.

[0033] See Figure 2 and Figure 4 In some embodiments of this utility model, in order to avoid the problem of bacterial growth caused by long-term water residue in the water receiving tank, the upper surface of the upper end plate 121 is recessed downward to form a guide channel 124 that guides the water in the water receiving tank to the water outlet 123. The depth of the guide channel 124 gradually increases towards the water outlet 123, so that the condensate can flow immediately towards the water outlet 123 along the extension direction of the guide channel 124 after entering the water receiving tank.

[0034] See Figure 4In some embodiments of this utility model, the upper surface of the upper end plate 121 is provided with a first inclined surface 1241 and a second inclined surface 1242. The first inclined surface 1241 and the second inclined surface 1242 intersect to form a guide groove 124 with a "V" shaped cross-section. One end of the ridge line where the first inclined surface 1241 and the second inclined surface 1242 intersect is located directly above the upper end of the guide member 300. It can be understood that the formation of condensate is slow and continuous. Water droplets on the first inclined surface 1241 and the second inclined surface 1242 will flow towards the bottom of the "V" shaped guide groove 124, thereby concentrating the water droplets into a small stream of water that flows orderly to the upper end of the guide member 300. Then, under the action of gravity, it flows downward along the guide member 300, reducing the possibility that the water stream will not contact the guide member 300.

[0035] See Figure 4 In some embodiments of this utility model, the guide member 300 is a strip-shaped guide plate formed on the inner wall of the water tank 100. The strip-shaped guide plate extends from top to bottom to the inner bottom wall of the water tank 100. The upper end of the side of the strip-shaped guide plate away from the inner wall of the water tank 100 is connected to a guide slope 310 inclined towards the inner wall of the water tank 100. It can be understood that the guide slope 310 makes the upper end of the strip-shaped guide plate form a sharp part. When a thin stream or water droplet encounters the sharp part, it is easier to form a wall adhesion effect. When receiving free-falling water droplets, it can reduce the resistance in the initial stage of flow, thereby more smoothly transitioning to a downward flow state along the strip-shaped guide plate.

[0036] In this embodiment, the water tank 100 is made of plastic, allowing the strip-shaped flow guide plate to be directly molded during injection molding, making production and processing very convenient and inexpensive. Of course, in other embodiments, the flow guide 300 can also be replaced by a water trough component disposed close to the inner wall of the water tank 100.

[0037] In some embodiments of this utility model, the width direction of the strip-shaped diversion plate is perpendicular to the inner wall of the water tank 100, and the width of the strip-shaped diversion plate gradually increases from top to bottom. The upper end of the strip-shaped diversion plate is narrower to cooperate with the guide slope 310 for diversion, while the lower end of the strip-shaped diversion plate is wider to provide a wider channel for high-speed water flow and increase the adhesion area of ​​the water flow.

[0038] See Figure 1 and Figure 5In some embodiments of this utility model, the dehumidifying body 200 has a working state and an idle state. When the dehumidifying body 200 is in the idle state, it is at least partially housed within the cavity. When the dehumidifying body 200 is in the working state, it is placed on the cover 120. It is understood that when the dehumidifying body 200 is in the idle state, with part or all of it housed within the cavity, the center of gravity of the dehumidifier is lowered, making its placement more stable and reducing the overall space occupied by the dehumidifier, facilitating storage and transportation. When the dehumidifying body 200 is in the working state, it forms a vertically stacked structure, occupying a smaller area on the ground, and the air outlet of the dehumidifying body 200 is positioned higher, allowing the dehumidified air to be diffused more quickly throughout the indoor space.

[0039] See Figure 2 In some embodiments of this utility model, in order to prevent the dehumidifying body 200 from falling off the water tank 100 due to collision, one of the upper end plate 121 and the base of the dehumidifying body 200 is provided with a positioning protrusion 125, and the other is provided with a positioning slot that cooperates with the positioning protrusion 125, so as to prevent the dehumidifying body 200 from horizontally displacing or rotating relative to the cover 120.

[0040] See Figure 3 In some embodiments of this utility model, the base of the dehumidifying body 200 is provided with four support feet 220 distributed at the four corners of the quadrilateral. The four support feet 220 are mounted on the upper end plate 121 to create a height space between the dehumidifying body 200 and the upper end plate 121, preventing water in the water tank from wetting the bottom of the dehumidifying body 200. The drainage structure 210 is a drain bend located within the height space. The outlet of the drain bend faces the water outlet 123, and the water output from the drain bend can be directly transmitted to the water outlet 123, which is more efficient and faster.

[0041] See Figure 1 In some embodiments of this utility model, in order to facilitate the overall movement of the dehumidifier or the movement of the water tank 100 itself, the bottom of the water tank 100 is provided with a plurality of roller assemblies 130.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
