Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of household appliances, in particular to a dehumidifier. BACKGROUND

[0002] The dehumidifier is also called a moisture extractor, a dryer, or a dehumidifier, which can be divided into two categories of household dehumidifiers and industrial dehumidifiers and belongs to a member of air conditioning families. Generally, a conventional dehumidifier is composed of a compressor, a heat exchanger, a fan, a water tank, a casing, and a controller. The working principle is that the fan draws in the humid air into the machine, and the water molecules in the air are condensed into water droplets through the heat exchange component, and the dry air after treatment is discharged out of the machine, so that the indoor humidity is maintained at a suitable relative humidity.

[0003] The inventor found that the existing dehumidifiers on the market generally only have one set of normal flow holes in the partition plate. If there are foreign matters in the waterway during use, it may cause blockage, or if it is used in a relatively humid environment, the water may be produced too fast, which may cause the water to not be normally drained into the water tank through the normal set of water leakage parts. SUMMARY

[0004] The purpose of the present application is to provide a dehumidifier that can ensure that water is normally drained into the water tank when the holes are blocked or the water is produced too fast.

[0005] The embodiments of the present application are implemented as follows:

[0006] In a first aspect, the present application provides a dehumidifier, comprising:

[0007] a water tank;

[0008] a partition plate having a water receiving tray above the water tank, the water receiving tray having a water drainage flow channel, a first water leakage part, and a second water leakage part, the first water leakage part being located on the water drainage flow channel, the first water leakage part and the second water leakage part each having at least one water leakage hole in communication with the water tank, the first water leakage part having a first shielding plate and a second shielding plate on both sides, the height of the first shielding plate being higher than that of the second shielding plate in the height direction, and the second water leakage part being located on the side of the second shielding plate away from the first water leakage part;

[0009] a heat exchange component including an evaporator and a condenser arranged on the water receiving tray.

[0010] Through the above arrangement, when the first water leakage part is blocked or the water production speed is greater than the water leakage speed of the water leakage hole of the first water leakage part, the water will overflow the second shielding plate and flow into the water leakage hole of the second water leakage part, and then flow into the water tank from the water leakage hole of the second water leakage part. This ensures that the water can be normally drained into the water tank.

[0011] In an optional embodiment, the partition plate is further provided with a plurality of water-proof protrusions arranged on the water pan, and the water-proof protrusions are arranged on the water drainage channel.

[0012] Through the above arrangement, the water tension can be broken by the water-proof protrusions, so that the water flow is not easy to be adsorbed on the rib plate of the water pan.

[0013] In an optional embodiment, at least part of the water drainage channel extends along the length direction of the partition plate, at least part of the water-proof protrusions extends along the length direction, and at least part of the water-proof protrusions are arranged along the length direction.

[0014] Through the above arrangement, the water flow can be separated for a long distance, so that the water tension can be broken efficiently, and the water is not easy to be adsorbed on the rib plate of the water pan.

[0015] In an optional embodiment, the water pan is further provided with a direct drainage opening, the water drainage channel comprises a first flow channel and a second flow channel which are sequentially connected, the first water leakage part is located at one end of the second flow channel away from the first flow channel, the direct drainage opening is connected with the first flow channel, the water pan is provided with a first support rib, a second support rib, a third support rib and a fourth support rib which are sequentially arranged along the width direction of the water pan, the evaporator is connected with the first support rib and the second support rib, the condenser is connected with the third support rib and the fourth support rib, and the side of the third support rib close to the second support rib and the first support rib jointly define the first flow channel.

[0016] Through the above arrangement, when the water accumulates, the water flows along the first flow channel to the second flow channel, when the direct drainage opening is opened, the water flows out of the direct drainage opening. When the direct drainage opening is blocked, the water flows from the first flow channel to the second flow channel in turn, under normal circumstances, the water flows into the water tank through the water leakage hole of the first water leakage part, when the first water leakage part is blocked or the water production speed is greater than the water leakage speed of the water leakage hole of the first water leakage part, the water overflows the second shielding plate and flows into the water tank through the water leakage hole of the second water leakage part.

[0017] In an optional embodiment, the dehumidifier further comprises a top cover, the top cover covers the evaporator and the condenser, the height dimension of the evaporator is smaller than the height dimension of the condenser, and the height of the first support rib and the second support rib is higher than the height of the third support rib and the fourth support rib, so that the upper parts of the evaporator and the condenser are flush.

[0018] Through the above arrangement, the height of the first support rib and the second support rib can be increased to make the upper parts of the evaporator and the condenser flush.

[0019] In an optional embodiment, the bottom surface of the water pan is inclined, and the height of the first flow channel gradually decreases in the direction close to the second flow channel.

[0020] Through the above setting, the water flow speed is improved to increase the water entering rate into the water tank.

[0021] In an optional embodiment, the height dimension of the first support rib, the second support rib, the third support rib and the fourth support rib gradually increases from the end close to the bottom of the water receiving tray to the end away from the water receiving tray in the direction of the first flow channel.

[0022] Through the above setting, the evaporator on the first support rib and the second support rib and the condenser on the third support rib and the fourth support rib can be horizontally installed.

[0023] In an optional embodiment, the water receiving tray further protrudes a water blocking rib extending along the extending direction of the first flow channel, the water blocking rib is located at the end of the first flow channel away from the second flow channel, the water blocking rib is arranged between the second support rib and the third support rib, and the height dimension of the water blocking rib is higher than that of the third support rib.

[0024] Through the above setting, the water in the first flow channel is less likely to enter between the third support rib and the fourth support rib, preventing overflow in the area where the condenser is installed.

[0025] In an optional embodiment, the water leakage hole of the first water leakage part includes a water outlet hole and an overflow hole, a partition plate is arranged between the water outlet hole and the overflow hole, the height dimension of the partition plate is higher than that of the water outlet hole, and the height dimension of the partition plate is less than that of the second shielding plate.

[0026] Through the above setting, when the water outlet hole is blocked or the water production speed is greater than the water leakage speed of the water leakage hole of the water outlet hole, the water flow will overflow the partition plate and then flow into the water tank through the overflow hole.

[0027] In an optional embodiment, the water tank includes a water tank body and a water tank cover connected together, the water tank cover is located below the water receiving tray, the water tank cover is provided with a water inlet hole communicating with the water leakage hole, and the inner wall of the water inlet hole has an inclined water guide slope.

[0028] Through the above setting, the water on the water tank cover can enter the water tank more efficiently.

[0029] The beneficial effect of the embodiment of the present application is that the dehumidifier provided by the embodiment of the present application comprises a water tank, a middle partition plate and a heat exchange assembly. The middle partition plate has a water receiving tray above the water tank. The water receiving tray has a water drainage flow channel, a first water leakage part and a second water leakage part. The first water leakage part is located on the water drainage flow channel. The first water leakage part and the second water leakage part both have water leakage holes in communication with the water tank. The first water leakage part has at least one first shielding plate and one second shielding plate on both sides. In the height direction, the height of the first shielding plate is higher than that of the second shielding plate. The second water leakage part is located on the side of the second shielding plate away from the first water leakage part. The heat exchange assembly comprises an evaporator and a condenser arranged on the water receiving tray. When the first water leakage part is blocked or the water production speed is greater than the water leakage speed of the water leakage hole of the first water leakage part, water will overflow the second shielding plate and flow into the water leakage hole of the second water leakage part, and then flow into the water tank from the water leakage hole of the second water leakage part. Thus, it is ensured that water can be normally drained into the water tank. BRIEF DESCRIPTION OF DRAWINGS

Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments.

[0041] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0042] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship when the product of the present application is usually placed, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" and the like are only used for differentiation in description, and cannot be understood as indicating or implying relative importance.

[0043] In addition, the terms "horizontal", "vertical", and the like, do not mean that the components must be absolutely horizontal or vertical, but can be slightly inclined. For example, "horizontal" only means that it is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly inclined.

[0044] In the description of the present application, it should be noted that, unless otherwise specified and limited, the terms "set", "install", "connect", "connect" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or it can be electrically connected; it can be directly connected, or it can be indirectly connected through an intermediate medium, or it can be connected inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The specific structure of the dehumidifier and the corresponding technical effects brought by the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0046] Please refer to Figures 1-5 The dehumidifier 1 provided by the embodiment of the present application comprises a water tank 10, a partition plate 20 and a heat exchange assembly 30. The partition plate 20 has a water receiving tray 21 located above the water tank 10. The water receiving tray 21 has a water drainage channel 211, a first water leakage portion 212 and a second water leakage portion 213. The first water leakage portion 212 is located on the water drainage channel 211. The first water leakage portion 212 and the second water leakage portion 213 both have water leakage holes communicating with the water tank 10. The first water leakage portion 212 has at least one first shielding plate 22 and a second shielding plate 23 on both sides. In the height direction, the height of the first shielding plate 22 is higher than that of the second shielding plate 23. The second water leakage portion 213 is located on the side of the second shielding plate 23 away from the first water leakage portion 212. The heat exchange assembly 30 comprises an evaporator 31 and a condenser 32 arranged on the water receiving tray 21.

[0047] It is easy to understand that the water on the water receiving tray 21 can flow on the water drainage channel 211, and the first water leakage portion 212 is located on the water drainage channel 211. Therefore, when the water flows, it can flow into the water tank 10 through the water leakage holes on the first water leakage portion 212. When the water leakage holes on the first water leakage portion 212 are blocked, or when the dehumidifier 1 is located in a humid environment and water is produced too fast, water may overflow to other areas on the water receiving tray 21, so that the water cannot be normally discharged into the water tank 10 through the water leakage holes of the first water leakage portion 212. At this time, the water will accumulate between the first shielding plate 22 and the second shielding plate 23, until the water level is higher than the second shielding plate 23, and the water can be discharged into the water tank 10 through the water leakage holes of the second water leakage portion 213 on the side of the second shielding plate 23 away from the first water leakage portion 212.

[0048] In other words, the water leakage hole of the second water leakage part 213 can be understood as a backup water leakage hole. When the water leakage hole of the first water leakage part 212 can normally drain water into the water tank 10, the water leakage hole of the second water leakage part 213 will not play a role in water leakage. Only when the first water leakage part 212 is blocked or the water production rate is greater than the water leakage rate of the water leakage hole of the first water leakage part 212, water will overflow the second baffle 23 and flow into the water leakage hole of the second water leakage part 213, and then flow into the water tank 10 from the water leakage hole of the second water leakage part 213.

[0049] With Figure 1 For reference, the dehumidifier 1 has a height direction, a length direction, and a width direction. The height direction is the a direction, the length direction is the b direction, and the width direction is the c direction.

[0050] Further, the middle partition plate 20 is further provided with a plurality of water isolation protrusions 29 arranged on the water pan 21, and the water isolation protrusions 29 are located on the water drainage flow channel 211.

[0051] It should be noted that the water isolation protrusions 29 are used to break the tension of water, so that the water flow is not easy to be adsorbed on the rib plate of the water pan 21.

[0052] Specifically, in the present embodiment, at least part of the water drainage flow channel 211 extends along the length direction of the middle partition plate 20, at least part of the water isolation protrusions 29 extends along the length direction of the middle partition plate 20, and at least part of the water isolation protrusions 29 are arranged along the length direction.

[0053] It can be understood that when water flows in the water drainage flow channel 211 extending along the length direction of the middle partition plate 20, the water isolation protrusions 29 extending along the length direction are arranged, and the water flow can be divided by the water isolation protrusions 29 extending along the length direction. The extension direction of the water isolation protrusions 29 extending along the length direction is consistent with the flow direction of the water, and at least part of the water isolation protrusions 29 are arranged along the length direction, which can separate the water flow for a long distance, thereby efficiently breaking the tension of the water and avoiding the water from being adsorbed on the rib plate of the water pan 21.

[0054] Please continue to refer to Figure 3In detail, in the embodiment, the water pan 21 is further provided with a direct drainage opening 214, the water drainage channel 211 comprises a first channel 2111 and a second channel 2112 which are sequentially communicated, the direct drainage opening 214 is communicated with the first channel 2111, the first water leakage part 212 is located at one end of the second channel 2112 which is away from the first channel 2111, the water pan 21 is provided with the first support rib 24, the second support rib 25, the third support rib 26 and the fourth support rib 27 which are sequentially and spaced arranged along the width direction of the water pan 21, the evaporator 31 is connected with the first support rib 24 and the second support rib 25, specifically, the evaporator 31 is arranged on the first support rib 24 and the second support rib 25, the condenser 32 is connected with the third support rib 26 and the fourth support rib 27, and the side of the third support rib 26 which is close to the second support rib 25 and the first support rib 24 jointly define the first channel 2111.

[0055] In the embodiment, the plurality of water isolation protrusions 29 are arranged on the first channel 2111, and the first channel 2111 extends along the length direction of the water pan 21.

[0056] It is easy to understand that the water of the water drainage channel 211 is mostly the condensed water which falls on the water pan 21 from the evaporator 31, and the water flows along the first channel 2111 to the second channel 2112 in the process of accumulation, and when the direct drainage opening 214 is opened, the water flows out from the direct drainage opening 214.

[0057] When the direct drainage opening 214 is blocked, the water sequentially flows from the first channel 2111 to the second channel 2112, and under normal circumstances, the water flows into the water tank 10 from the water leakage hole of the first water leakage part 212, when the first water leakage part 212 is blocked or the water production speed is greater than the water leakage speed of the water leakage hole of the first water leakage part 212, the water overflows the second shielding plate 23 and flows into the water tank 10 from the water leakage hole of the second water leakage part 213.

[0058] Further, the dehumidifier 1 further comprises a top cover 40 which covers the evaporator 31 and the condenser 32, the height dimension of the evaporator 31 is less than that of the condenser 32, in order to keep the side of the evaporator 31 which is connected with the top cover 40 flush with the evaporator 31, so that the top cover 40 can stably cover the evaporator 31 and the condenser 32, and the height of the first support rib 24 and the second support rib 25 in the embodiment is higher than that of the third support rib 26 and the fourth support rib 27, so that the upper parts of the evaporator 31 and the condenser 32 are flush.

[0059] Further, in order to improve the water flow speed and increase the rate of water entering the water tank 10, in the embodiment, the bottom wall of the water pan 21 is inclined, and the height of the first channel 2111 gradually decreases in the direction close to the second channel 2112.

[0060] In order to ensure that the evaporator 31 on the first support rib 24 and the second support rib 25 and the condenser 32 on the third support rib 26 and the fourth support rib 27 can be installed horizontally, that is, to make the first support rib 24, the second support rib 25, the third support rib 26 and the fourth support rib 27 away from the bottom end of the water pan 21 horizontally arranged, therefore, in the direction of the first flow channel 2111 close to the second flow channel 2112, the height dimension of the first support rib 24, the second support rib 25, the third support rib 26 and the fourth support rib 27 close to the end of the bottom wall of the water pan 21 gradually increases away from the end of the water pan 21.

[0061] It is easy to understand that at the end of the first flow channel 2111 away from the second flow channel 2112, the height dimension of the third support rib 26 is lower, therefore, in the present embodiment, the water pan 21 is further provided with a water blocking rib 28 extending along the extension direction of the first flow channel 2111, the water blocking rib 28 is located at the end of the first flow channel 2111 away from the second flow channel 2112, the water blocking rib 28 is arranged between the second support rib and the third support rib 26, and the height dimension of the water blocking rib 28 is higher than that of the third support rib 26.

[0062] Therefore, through the arrangement of the water blocking rib 28, the water in the first flow channel 2111 is not easy to enter between the third support rib 26 and the fourth support rib 27, and overflow in the area where the condenser 32 is installed is prevented.

[0063] Please continue to refer to Figures 4-5 , specifically, in the present embodiment, the water leakage hole of the first water leakage part 212 includes a water outlet hole 2121 and an overflow hole 2122, a partition plate 2123 is arranged between the water outlet hole 2121 and the overflow hole 2122, the height dimension of the partition plate 2123 is higher than that of the water outlet hole 2121, and the height dimension of the partition plate 2123 is smaller than that of the second shielding plate 23. And the water outlet hole 2121 is close to the first flow channel 2111 relative to the overflow hole 2122. That is, in the process of water flowing, the water will first enter the water tank 10 from the water outlet hole 2121, when the water outlet hole 2121 is blocked or the water production rate is greater than the water leakage rate of the water leakage hole of the water outlet hole 2121, the water flow will overflow the partition plate 2123, and then flow into the water tank 10 through the overflow hole 2122.

[0064] Please refer to Figures 6-7 , in the present embodiment, the second water leakage part 213 has two water leakage holes.

[0065] Further, the water tank 10 comprises a water tank body 11 and a water tank cover 12 connected with each other, the water tank cover 12 is located at the lower side of the water receiving disc 21, and the water tank cover 12 is provided with a water inlet 122 communicated with the water leakage hole. The inner wall of the water inlet 122 is provided with a water guide inclined surface 1221. It can be understood that the water on the water tank cover 12 can be more efficiently introduced into the water tank 10 through the water guide inclined surface 1221.

[0066] Specifically, in the embodiment, the water tank cover 12 is further provided with a water receiving groove 121, and the water inlet 122 is arranged on the bottom wall of the water receiving groove 121. The water receiving groove 121 is located below the first water leakage part 212 and the second water leakage part 213.

[0067] In summary, the dehumidifier 1 provided by the embodiment of the present application comprises a water tank 10, a partition plate 20 and a heat exchange assembly 30. The partition plate 20 is provided with a water receiving disc 21 located above the water tank 10, the water receiving disc 21 is provided with a water drainage flow channel 211, a first water leakage part 212 and a second water leakage part 213, the first water leakage part 212 is located on the water drainage flow channel 211, the first water leakage part 212 and the second water leakage part 213 are both provided with a water leakage hole communicated with the water tank 10, the first water leakage part 212 is provided with at least one first shielding plate 22 and a second shielding plate 23 on both sides, in the height direction, the height of the first shielding plate 22 is higher than that of the second shielding plate 23, and the second water leakage part 213 is located on the side of the second shielding plate 23 away from the first water leakage part 212. The heat exchange assembly 30 comprises an evaporator 31 and a condenser 32 arranged on the water receiving disc 21. When the first water leakage part 212 is blocked or the water production speed is greater than the water leakage speed of the water leakage hole of the first water leakage part 212, the water will overflow the second shielding plate 23 and flow into the water leakage hole of the second water leakage part 213, and then flow into the water tank 10 from the water leakage hole of the second water leakage part 213. Thus, the water can be normally drained into the water tank 10.

[0068] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes.
