Description

Technical Field

[0001] The present invention relates to the technical field of household electrical appliances, and in particular to a dehumidifier. Background Art

[0002] Dehumidifiers are also called dehumidifiers, dryers, and dehumidifiers. They can generally be divided into two categories: civil dehumidifiers and industrial dehumidifiers. They are a member of the air-conditioning family. Usually, a conventional dehumidifier consists of a compressor, a heat exchanger, a fan, a water tank, a casing, and a controller. Its working principle is: the fan draws humid air into the machine, and through the heat exchange component, the water molecules in the air condense into water droplets, and the treated dry air is discharged from the machine. This cycle keeps the indoor humidity at a suitable relative humidity.

[0003] The inventors have discovered that dehumidifiers currently on the market generally only have one set of holes for normal circulation on their partitions. If there is foreign matter in the water path during use, it may cause blockage. Or if water is produced too quickly when operating in a relatively humid environment, the water may not be able to drain normally into the water tank through the normal set of leaking holes. Summary of the invention

[0004] The object of the present invention is to provide a dehumidifier which can ensure that water can be normally discharged into a water tank even when a group of holes is blocked or water is produced too quickly.

[0005] The embodiment of the present invention is achieved as follows:

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

[0007] Water tank;

[0008] A middle partition, the middle partition has a water receiving tray located above the water tank, the water receiving tray has a drainage channel, a first water leakage part and a second water leakage part, the first water leakage part is located on the drainage channel, the first water leakage part and the second water leakage part each have at least one water leakage hole connected to the water tank, the first water leakage part has a first shielding plate and a second shielding plate on both sides, in the height direction, the height of the first shielding plate is higher than the second shielding plate, and the second water leakage part is located on the side of the second shielding plate away from the first water leakage part;

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

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

[0011] In an optional embodiment, the middle partition is further provided with a plurality of water-isolating protrusions which are arranged at intervals on the water receiving tray, and the water-isolating protrusions are located on the drainage channel.

[0012] Through the above arrangement, the water-isolating protrusions can be used to destroy the tension of water, so that the water flow is not easily adsorbed on the rib plate of the water receiving tray.

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

[0014] Through the above arrangement, the water flow can be separated over a long distance, thereby effectively destroying the water tension and preventing the water from being adsorbed on the rib plate of the water receiving tray.

[0015] In an optional embodiment, the water receiving tray is also provided with a straight discharge port, the drainage channel includes a first channel and a second channel which are connected in sequence, the first water leakage portion is located at an end of the second channel away from the first channel, the straight discharge port is connected to the first channel, and the water receiving tray is provided with a first support rib, a second support rib, a third support rib and a fourth support rib which are arranged in sequence along its width direction at intervals, the evaporator is connected to the first support rib and the second support rib, the condenser is connected to 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 together define the first channel.

[0016] Through the above arrangement, water will flow along the first flow channel toward the second flow channel during the accumulation process, and when it flows and the direct discharge port is opened, the water will flow out from the direct discharge port. When the direct discharge port is blocked, water will flow from the first flow channel to the second flow channel in sequence. Under normal circumstances, water will flow into the water tank from the leakage hole of the first leaking part. When the first leaking part is blocked or the water production speed is greater than the leakage speed of the leakage hole of the first leaking part, water will overflow the second baffle plate and flow into the leakage hole of the second leaking part, and then flow into the water tank from the leakage hole of the second leaking part.

[0017] In an optional embodiment, the dehumidifier also includes a top cover, which is provided on the evaporator and the condenser. The height of the evaporator is smaller than the height of the condenser. The heights of the first support rib and the second support rib are higher than 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 upper parts of the evaporator and the condenser can be flush with each other by increasing the heights of the first supporting ribs and the second supporting ribs.

[0019] In an optional embodiment, the bottom wall of the water receiving tray is inclined, and the height of the first flow channel gradually decreases in a direction approaching the second flow channel.

[0020] Through the above arrangement, the water flow velocity is increased, so as to increase the rate at which water enters the water tank.

[0021] In an optional embodiment, in the direction in which the first flow channel approaches the second flow channel, the height dimensions of the first support rib, the second support rib, the third support rib and the fourth support rib gradually increase from one end close to the bottom wall of the water receiving tray to the other end away from the water receiving tray.

[0022] Through the above arrangement, it is ensured that the evaporator on the first supporting rib and the second supporting rib and the condenser on the third supporting rib and the fourth supporting rib can be installed horizontally.

[0023] In an optional embodiment, a water retaining rib extending along the extension direction of the first flow channel is also protruding on the water receiving tray. The water retaining rib is located at one end of the first flow channel away from the second flow channel. The water retaining rib is arranged between the second support rib and the third support rib. The height dimension of the water retaining rib is higher than the height dimension of the third support rib.

[0024] Through the above arrangement, it is difficult for water in the first flow channel to enter between the third supporting rib and the fourth supporting rib, thereby preventing the water from overflowing over the area where the condenser is installed.

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

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

[0027] In an optional embodiment, the water tank includes a connected water tank body and a water tank cover, the water tank cover is located on the lower side of the water receiving tray, the water tank cover is provided with a water inlet connected to the leakage hole, and the inner wall of the water inlet has an inclined water guiding slope.

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

[0029] The beneficial effect of the embodiment of the present invention is as follows: a dehumidifier provided by the embodiment of the present invention includes a water tank, a middle partition and a heat exchange component. The middle partition has a water receiving tray located above the water tank, the water receiving tray has a drainage channel, a first water leakage part and a second water leakage part, the first water leakage part is located on the drainage channel, the first water leakage part and the second water leakage part both have a water leakage hole connected to the water tank, the first water leakage part has at least one first baffle and a second baffle on both sides, in the height direction, the height of the first baffle is higher than the second baffle, and the second water leakage part is located on the side of the second baffle away from the first water leakage part. The heat exchange component includes 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 baffle and flow into the water leakage hole of the second water leakage part, and flow into the water tank from the water leakage hole of the second water leakage part. Thereby ensuring that water can be discharged into the water tank normally. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, or the positions or positional relationships in which the product of the invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", "third", etc. are only used to distinguish the 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 are required to be absolutely horizontal or suspended, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0044] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0045] The specific structure of a dehumidifier provided by an embodiment of the present invention and the corresponding technical effects it brings are described in detail below in conjunction with the patent drawings.

[0046] Please refer to Figure 1-Figure 5 A dehumidifier 1 provided in an embodiment of the present invention includes a water tank 10, a middle partition 20 and a heat exchange assembly 30. The middle partition 20 has a water receiving tray 21 located above the water tank 10, and the water receiving tray 21 has a drainage 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 drainage channel 211. Both the first water leakage part 212 and the second water leakage part 213 have water leakage holes connected to the water tank 10. The first water leakage part 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 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 includes 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 drainage channel 211, and the first water leakage part 212 is located on the drainage channel 211. Therefore, when the water flows, it can flow into the water tank 10 through the leakage hole on the first water leakage part 212. When the leakage hole on the first water leakage part 212 is blocked, or when the dehumidifier 1 is located in a humid environment and produces water too quickly, the 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 leakage hole of the first water leakage part 212. At this time, the water will accumulate between the first baffle plate 22 and the second baffle plate 23 until the water level is higher than the second baffle plate 23. Then, the water can be discharged into the water tank 10 through the leakage hole of the second water leakage part 213 on the side of the second baffle plate 23 away from the first water leakage part 212.

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

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

[0050] Furthermore, the middle partition plate 20 is also provided with a plurality of water-isolating protrusions 29 which are arranged at intervals on the water receiving tray 21 , and the water-isolating protrusions 29 are located on the drainage channel 211 .

[0051] It should be noted that the water-isolating protrusions 29 are used to break the tension of water so that the water flow is not easily adsorbed on the rib plate of the water receiving tray 21 .

[0052] Specifically, in this embodiment, at least part of the drainage channel 211 extends along the length direction of the middle partition 20, at least part of the water-isolating protrusions 29 extends along the length direction of the middle partition 20, and at least part of the water-isolating protrusions 29 are arranged at intervals along the length direction.

[0053] It can be understood that when water flows in the drainage channel 211 extending along the length direction of the middle partition 20, it has water-isolating protrusions 29 extending along the length direction. When the water flows, it can be divided by the water-isolating protrusions 29 extending along the length direction. The extension direction of the water-isolating protrusions 29 extending along the length direction is consistent with the flow direction of the water, and at least part of the water-isolating protrusions 29 are spaced apart along the length direction, which can separate the water flow over a long distance, thereby effectively destroying the water tension and preventing water from being adsorbed on the rib plate of the water receiving tray 21.

[0054] Please continue to refer to Figure 3In detail, in the present embodiment, the water receiving tray 21 is further provided with a straight discharge port 214, and the drainage channel 211 includes a first channel 2111 and a second channel 2112 which are connected in sequence. The straight discharge port 214 is connected to the first channel 2111, and the first water leakage portion 212 is located at an end of the second channel 2112 away from the first channel 2111. The water receiving tray 21 is provided with a first support rib 24, a second support rib 25, a third support rib 26 and a fourth support rib 27 which are arranged in sequence along its width direction at intervals. The evaporator 31 is connected to 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, and the condenser 32 is connected to the third support rib 26 and the fourth support rib 27. The side of the third support rib 26 close to the second support rib 25 and the first support rib 24 together define the first channel 2111.

[0055] In this embodiment, the plurality of water-isolating protrusions 29 are all disposed on the first flow channel 2111 , and the first flow channel 2111 extends along the length direction of the water receiving tray 21 .

[0056] It is easy to understand that the water in the drainage channel 211 is mostly condensed water that falls from the evaporator 31 onto the water receiving tray 21. During the accumulation process, the water will flow along the first channel 2111 in the direction approaching the second channel 2112. When it flows and the direct discharge port 214 is opened, the water will flow out from the direct discharge port 214.

[0057] When the direct discharge port 214 is blocked, water flows from the first flow channel 2111 to the second flow channel 2112 in sequence. Under normal circumstances, water will flow into the water tank 10 from the leakage hole of the first leakage part 212. When the first leakage part 212 is blocked or the water production speed is greater than the leakage speed of the leakage hole of the first leakage part 212, water will overflow the second baffle plate 23 and flow into the leakage hole of the second leakage part 213, and flow into the water tank 10 from the leakage hole of the second leakage part 213.

[0058] Furthermore, the dehumidifier 1 also includes a top cover 40, which is used to cover the evaporator 31 and the condenser 32. The height of the evaporator 31 is smaller than the height of the condenser 32. In order to keep the side of the evaporator 31 connected to the top cover 40 flush with the evaporator 31, so that the top cover 40 can be stably covered on the evaporator 31 and the condenser 32, the height of the first support rib 24 and the second support rib 25 in this embodiment is higher than the third support rib 26 and the fourth support rib 27 so that the upper part of the evaporator 31 is flush with the upper part of the condenser 32.

[0059] Furthermore, in order to increase the water flow speed, so as to increase the speed of water entering the water tank 10, in this embodiment, the bottom wall of the water receiving tray 21 is inclined, and the height of the first flow channel 2111 gradually decreases in the direction close to the second flow 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 The end away from the bottom of the water receiving tray 21 is horizontally arranged, therefore, in the direction where the first flow channel 2111 approaches the second flow channel 2112, the height dimensions 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 bottom wall of the water receiving tray 21 and the end away from the water receiving tray 21 gradually increase.

[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 this embodiment, the water receiving tray 21 is also provided with a water retaining rib 28 extending along the extension direction of the first flow channel 2111. The water retaining rib 28 is located at the end of the first flow channel 2111 away from the second flow channel 2112. The water retaining rib 28 is arranged between the second support member and the third support rib 26. The height dimension of the water retaining rib 28 is higher than the height dimension of the third support rib 26.

[0062] Therefore, the water retaining ribs 28 are arranged to prevent the water in the first flow channel 2111 from easily entering between the third supporting ribs 26 and the fourth supporting ribs 27 , thereby preventing the water from overflowing over the area where the condenser 32 is installed.

[0063] Please continue to refer to Figure 4-Figure 5 Specifically, in this embodiment, the leakage hole of the first water leakage part 212 includes a water outlet hole 2121 and an overflow hole 2122. A partition 2123 is provided between the water outlet hole 2121 and the overflow hole 2122. The height dimension of the partition 2123 is higher than the height dimension of the water outlet hole 2121, and the height dimension of the partition 2123 is lower than the height dimension of the second shielding plate 23. The water outlet hole 2121 is closer to the first flow channel 2111 than the overflow hole 2122. That is, in the process of water flow, 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 speed is greater than the water leakage speed of the leakage hole of the water outlet hole 2121, the water will overflow through the partition 2123, and then flow into the water tank 10 through the overflow hole 2122.

[0064] Please refer to Figure 6-Figure 7 In this embodiment, the second water leakage portion 213 has two water leakage holes.

[0065] Furthermore, the water tank 10 includes a water tank body 11 and a water tank cover 12 connected to each other. The water tank cover 12 is located at the lower side of the water receiving tray 21. The water tank cover 12 is provided with a water inlet 122 connected to the water leakage hole. The inner wall of the water inlet 122 has an inclined water guide slope 1221. It can be understood that the water on the water tank cover 12 can enter the water tank 10 more efficiently through the water guide slope 1221.

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

[0067] In summary, a dehumidifier 1 provided in an embodiment of the present invention includes a water tank 10, a middle partition 20 and a heat exchange assembly 30. The middle partition 20 has a water receiving tray 21 located above the water tank 10, the water receiving tray 21 has a drainage 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 drainage channel 211, the first water leakage part 212 and the second water leakage part 213 both have a water leakage hole connected to the water tank 10, and the first water leakage part 212 has at least one first baffle plate 22 and a second baffle plate 23 on both sides. In the height direction, the height of the first baffle plate 22 is higher than the second baffle plate 23, and the second water leakage part 213 is located on the side of the second baffle plate 23 away from the first water leakage part 212. The heat exchange assembly 30 includes an evaporator 31 and a condenser 32 arranged on the water receiving tray 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, 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, it is ensured that water can be discharged into the water tank 10 normally.

For those skilled in the art, the present invention may have various modifications and variations.
