Description

Technical Field

[0001] The utility model belongs to the technical field of dehumidification and specifically provides a dehumidifier. Background Art

[0002] A dehumidifier, also known as a dehumidifier, dryer or dehumidifier, is an electrical device used to reduce the humidity of indoor air.

[0003] Existing dehumidifiers generally include a casing, a compressor, a condenser, an evaporator, a fan, etc. The casing is provided with an air inlet and an air outlet, and the evaporator and the condenser are arranged in sequence between the air inlet and the air outlet on the path of air flow. When the dehumidifier is working, the compressor runs to cool the evaporator and reduce the temperature. The fan drives the air into the casing from the air inlet, and flows through the evaporator and condenser in sequence, and finally flows out of the casing from the air outlet. When the air flows through the evaporator, the water molecules in the air condense into water droplets when they are cold, and become liquid water (often called condensed water). When the cooled air flows through the condenser, the condenser is cooled to improve the heat exchange efficiency of the condenser.

[0004] However, the heat exchange efficiency of the condenser of the existing dehumidifier is still low, which makes the temperature of the air blown out by the dehumidifier high, affecting the user experience. Utility Model Content

[0005] One purpose of the utility model is to solve the problem of low heat exchange efficiency of the condenser of the existing dehumidifier.

[0006] To achieve the above object, the utility model provides a dehumidifier, comprising:

[0007] an evaporator, used to cool the air entering the dehumidifier to condense gaseous water in the air into liquid;

[0008] A water receiving tray, arranged at the bottom side of the evaporator, for receiving condensed water flowing down from the evaporator;

[0009] A condenser, disposed on the top side of the water receiving tray and located on one side of the evaporator in the thickness direction of the evaporator;

[0010] A water sprinkling trough is arranged on the top side of the condenser so that the water in the water sprinkling trough is sprinkled onto the condenser;

[0011] The pumping system is used to pump the condensed water in the water receiving tray into the water sprinkling trough.

[0012] Optionally, the water receiving tray is provided with a first receiving tank for accommodating the evaporator and a second receiving tank for accommodating the condenser.

[0013] Optionally, the water receiving tray is provided with a plurality of supporting ribs in the first receiving groove and the second receiving groove, respectively, so that a gap allowing condensed water to flow is formed between the evaporator and the bottom surface of the first receiving groove and between the condenser and the bottom surface of the second receiving groove.

[0014] Optionally, a water storage tank is further provided on the water receiving tray, and the water storage tank is used to hold condensed water from the first receiving tank and the second receiving tank; the water inlet end of the pumping system is located in the water storage tank.

[0015] Optionally, the water receiving tray is further provided with an overflow groove and an overflow hole connected to the overflow groove, so that the condensed water in the water storage tank can overflow into the overflow groove and flow out from the overflow hole.

[0016] Optionally, a drainage hole is provided on the bottom side of the water storage tank to drain the condensed water in the water storage tank through the drainage hole; and / or, the water storage tank is located on a side of the second receiving tank away from the first receiving tank.

[0017] Optionally, the water sprinkling trough is formed on the top of the condenser, or the water sprinkling trough is fixedly connected to the condenser or is integrally formed therewith; and / or, a plurality of water sprinkling holes are provided on the bottom wall of the water sprinkling trough so that the condensed water in the water sprinkling trough is evenly sprinkled onto the condenser.

[0018] Optionally, the pumping system comprises a water pump and at least one water pipe.

[0019] Optionally, the inlet and outlet of the water pump are respectively connected to one of the water pipes, so that the water pump extracts condensed water in the water receiving tray through the water pipe, and pumps the extracted condensed water into the water shower tank through the water pipe.

[0020] Optionally, the dehumidifier also includes a casing and a fan, the fan has an air inlet and an air outlet, and the fan is used to drive air to flow from the air inlet to the air outlet; the evaporator and the condenser are arranged in sequence between the air inlet and the air outlet.

[0021] Based on the above description, those skilled in the art can understand that, in the aforementioned technical solution of the utility model, by arranging the condenser on the top side of the water receiving pan, arranging a water sprinkling tank on the top side of the condenser, and pumping the condensed water in the water receiving pan into the water sprinkling tank through a pumping system, the water in the water sprinkling tank is then sprinkled on the condenser to cool the condenser, thereby improving the heat exchange efficiency of the condenser. The water flowing down from the condenser will flow back into the water receiving pan, mix with the condensed water flowing down from the evaporator, and enter the next cycle again.

[0022] Those skilled in the art can also understand that, since the condensed water condensed by the evaporator is at a relatively low temperature, the condenser can be cooled by the evaporator, thereby fully utilizing the cold energy generated during the use of the dehumidifier and reducing the energy consumption of the dehumidifier.

[0023] Furthermore, by providing a first receiving tank for placing the evaporator and a second receiving tank for placing the condenser on the water receiving tray, the evaporator and the condenser can be installed on the water receiving tray, making the structure of the dehumidifier more compact, which is conducive to miniaturization of the dehumidifier.

[0024] Furthermore, by arranging a plurality of supporting ribs in the first receiving tank and the second receiving tank, a gap is formed between the evaporator and the bottom surface of the first receiving tank and between the condenser and the bottom surface of the second receiving tank to allow condensed water to flow. Therefore, the utility model avoids the accumulation of condensed water in the first receiving tank and the second receiving tank, thereby preventing the accumulated condensed water from breeding bacteria.

[0025] Furthermore, by arranging an overflow groove and an overflow hole connected to the overflow groove on the water receiving tray, the condensed water in the water storage tank can overflow into the overflow groove and flow out from the overflow hole, thereby preventing excessive condensed water in the water storage tank from overflowing onto the ground.

[0026] Furthermore, by providing a drainage hole on the bottom side of the water storage tank, the user can drain the condensed water in the water storage tank through the drainage hole when the dehumidifier is not in use.

[0027] Furthermore, by arranging a plurality of water sprinkling holes on the bottom wall of the water sprinkling trough, the condensed water in the water sprinkling trough can be evenly sprinkled onto the condenser through the plurality of water sprinkling holes, thereby evenly cooling the condenser.

[0028] Other beneficial effects of the present invention will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can more clearly understand the improved purposes, features and advantages of the present invention.

[0036] It should be understood by those skilled in the art that the embodiments described below are only a part of the embodiments of the present invention, rather than all the embodiments of the present invention, and the embodiments are intended to explain the technical principles of the present invention, rather than to limit the protection scope of the present invention. Based on the embodiments provided by the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should still fall within the protection scope of the present invention.

[0037] It should be noted that in the description of the present invention, the terms "center", "upper", "lower", "top", "bottom", "left", "right", "vertical", "horizontal", "inside", "outside" and the like indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings, which are only for the convenience of description, and do not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0041] like Figure 1 As shown, in some embodiments of the present invention, the dehumidifier 001 includes an evaporator 100 , a water receiving tray 200 , a condenser 300 , a water sprinkling tank 400 and a pumping system 500 .

[0042] The evaporator 100 is used to cool the air entering the dehumidifier 001 so as to condense the gaseous water in the air into liquid.

[0043] The water receiving tray 200 is disposed at the bottom side of the evaporator 100 to receive condensed water flowing down from the evaporator 100 .

[0044] The condenser 300 is disposed on the top side of the water receiving tray 200 , and is located at one side of the evaporator 100 in the thickness direction of the evaporator 100 .

[0045] The water sprinkling tank 400 is disposed on the top side of the condenser 300 so that the water in the water sprinkling tank 400 is sprinkled onto the condenser 300 .

[0046] The pumping system 500 is used to pump the condensed water 510 in the water receiving tray 200 into the water shower tank 400 .

[0047] Those skilled in the art can understand that, in some embodiments of the present invention, by arranging the condenser 300 on the top side of the water receiving tray 200, arranging the water sprinkling tank 400 on the top side of the condenser 300, and pumping the condensed water pump 510 in the water receiving tray 200 to the water sprinkling tank 400 through the pumping system 500, the water in the water sprinkling tank 400 is sprinkled on the condenser 300, the condenser 300 is cooled, and the heat exchange efficiency of the condenser 300 is improved. The water flowing down from the condenser 300 will flow back into the water receiving tray 200, mix with the condensed water flowing down from the evaporator 100, and enter the next cycle again.

[0048] Those skilled in the art can also understand that, since the temperature of the condensed water condensed by the evaporator 100 is relatively low, the condenser 300 is cooled by it, and the cold energy generated during the use of the dehumidifier 001 is fully utilized, thereby reducing the energy consumption of the dehumidifier 001.

[0049] Continue reading Figure 1 In some embodiments of the present invention, the dehumidifier 001 further includes a housing 600 and a fan 700 , the fan 700 has an air inlet 601 and an air outlet 602 , and the fan 700 is used to drive air to flow from the air inlet 601 to the air outlet 602 .

[0050] from Figure 1 It can be seen that the evaporator 100 , the water receiving tray 200 , the condenser 300 , the water sprinkling tank 400 , the pumping system 500 and the fan 700 are all arranged in the casing 600 .

[0051] from Figure 1 It can also be seen that the evaporator 100 and the condenser 300 are arranged in sequence between the air inlet 601 and the air outlet 602, so that under the action of the fan 700, the air flows through the air inlet 601, the evaporator 100, the condenser 300 and the air outlet 602 in sequence.

[0052] like Figure 2 As shown, in some embodiments of the present invention, in order to achieve the purpose of condensing air in the evaporator 100, the dehumidifier 001 also includes a compressor 800 and a pressure reduction component 900, and the compressor 800, the condenser 300, the pressure reduction component 900 and the evaporator 100 are connected end to end in sequence to form a refrigerant system.

[0053] The pressure reducing component 900 may be an electronic expansion valve, a capillary tube, or any other feasible component.

[0054] Those skilled in the art can understand that when the compressor 800 is working, the refrigerant circulates along the following path: compressor 800 → condenser 300 → pressure reducing component 900 → evaporator 100 → compressor 800 .

[0055] When the refrigerant flows through the compressor 800 , it is compressed by the compressor 800 into a high-temperature and high-pressure state (liquid state or a gas-liquid mixed state).

[0056] When the refrigerant flows through the condenser 300, the refrigerant dissipates heat through the condenser 300 and is cooled to a low-temperature and high-pressure state (liquid state or gas-liquid mixed state).

[0057] When the refrigerant flows through the pressure reducing component 900 , the refrigerant is throttled and reduced in pressure by the pressure reducing component 900 to a low-temperature and low-pressure state (liquid state or gas-liquid mixed state).

[0058] When the refrigerant flows through the evaporator 100, it absorbs heat from the external environment through the evaporator 100 and is heated to a high-temperature and low-pressure state (gaseous state).

[0059] It should be noted that the aforementioned states of the refrigerant in the compressor 800, the condenser 300, the pressure reducing component 900, and the evaporator 100, i.e., the high temperature, low temperature, high pressure, and low pressure of the refrigerant, are the states of the refrigerant after it enters the corresponding components or flows out of the corresponding components compared to the states before it flows into the corresponding components.

[0060] like Figure 1 and Figure 3 As shown, in some embodiments of the present invention, the water sprinkling trough 400 is formed on the top of the condenser 300, or the water sprinkling trough 400 is fixedly connected to or integrally formed with the condenser 300, and a plurality of water sprinkling holes 410 are provided on the bottom wall of the water sprinkling trough 400 so that the condensed water in the water sprinkling trough 400 is evenly sprinkled onto the condenser 300.

[0061] Further, if the evaporator 100 is a fin type heat exchanger, the fins thereof are perpendicular to the condenser 300 to ensure air flow.

[0062] Further, if the condenser 300 is a finned heat exchanger, the fins thereof are perpendicular to the evaporator 100 to ensure air flow.

[0063] Continue reading Figure 1 and Figure 3 In some embodiments of the present invention, the pumping system 500 includes a water pump 510 and at least one water pipe 520 .

[0064] The water pump 510 may be installed on the water receiving tray 200, or on the condenser 300, or on the housing 600. Alternatively, those skilled in the art may also install the water pump 510 on any other feasible component as required.

[0065] Furthermore, the inlet and outlet of the water pump 510 are respectively connected to a water pipe 520 , so that the water pump 510 extracts condensed water in the water receiving tray 200 through the water pipe 520 , and delivers the condensed water extracted by the condensed water pump 510 to the water shower trough 400 through the water pipe 520 .

[0066] In addition, in other embodiments of the present invention, those skilled in the art may also connect only one water pipe 520 to the inlet or outlet of the water pump 510 as needed.

[0067] like Figures 3 to 6 As shown, in some embodiments of the utility model, a first receiving groove 201 for placing the evaporator 100 and a second receiving groove 202 for placing the condenser 300 are provided on the water receiving tray 200, so that the evaporator 100 and the condenser 300 can be installed on the water receiving tray 200, making the structure of the dehumidifier 001 more compact, which is conducive to the miniaturization of the dehumidifier 001.

[0068] like Figures 4 to 6 As shown, in some embodiments of the utility model, the water receiving tray 200 is respectively provided with a plurality of supporting ribs 210 in the first receiving tank 201 and the second receiving tank 202, so that a gap allowing condensed water to flow is formed between the evaporator 100 and the bottom surface of the first receiving tank 201 and between the condenser 300 and the bottom surface of the second receiving tank 202.

[0069] It will be understood by those skilled in the art that by respectively arranging a plurality of support ribs 210 in the first receiving tank 201 and the second receiving tank 202, a gap allowing condensed water to flow is formed between the evaporator 100 and the bottom surface of the first receiving tank 201 and between the condenser 300 and the bottom surface of the second receiving tank 202.

[0070] It can be seen that the utility model can prevent condensed water from accumulating in the first containing tank 201 and the second containing tank 202, and further can prevent the accumulated condensed water from breeding bacteria.

[0071] from Figures 4 to 6 It can be seen that the support rib 210 in the first receiving groove 201 can be a V-shaped structure, and the support rib 210 in the second receiving groove 202 can be a multi-fold structure.

[0072] Of course, in other embodiments of the present invention, those skilled in the art can also set the support ribs 210 in the first receiving groove 201 and the support ribs 210 in the second receiving groove 202 to any other feasible structures as needed, such as a cross-shaped structure, a Y-shaped structure, etc.

[0073] like Figures 3 to 6As shown, in some embodiments of the present invention, a water storage tank 203 is further provided on the water receiving tray 200 , and the water storage tank 203 is used to receive condensed water from the first receiving tank 201 and the second receiving tank 202 .

[0074] from Figures 3 to 6 It can be seen that in some embodiments of the present invention, the water storage tank 203 is located on a side of the second containing tank 202 away from the first containing tank 201 .

[0075] In addition, in other embodiments of the present invention, those skilled in the art may also dispose the water storage tank 203 at any other feasible position as required.

[0076] For example, the water storage tank 203 is disposed between the first containing tank 201 and the second containing tank 202 .

[0077] Furthermore, in order to make the condensed water in the first receiving tank 201 flow to the water storage tank 203 and the condensed water in the second receiving tank 202 flow to the water storage tank 203, a first avoidance opening 2011 is provided at one end of the side wall of the first receiving tank 201 close to the water storage tank 203 and a second avoidance opening 2021 is provided at one end of the side wall of the second receiving tank 202 close to the water storage tank 203. Figures 4 to 6 The water flows to the water storage tank 203 as indicated by the dashed arrow.

[0078] Furthermore, the height of the bottom surface of the first containing tank 201 can be gradually reduced toward the water storage tank 203, so that the condensed water in the first containing tank 201 can flow to the water storage tank 203 under the action of gravity.

[0079] Similarly, the height of the bottom surface of the second receiving tank 202 can be gradually reduced toward the water storage tank 203, so that the condensed water in the second receiving tank 202 can flow to the water storage tank 203 under the action of gravity.

[0080] like Figure 3 As shown, the water inlet end of the pumping system 500 is located in the water storage tank 203. That is, the end of the water pipe 520 connected to the inlet of the water pump 510 away from the water pump 510 is located in the water storage tank 203.

[0081] Preferably, the water pipe 520 connected to the inlet of the water pump 510 extends from one end of the water pump 510 to the inner bottom wall of the water tank 203, or has a smaller distance from the inner bottom wall of the water tank 203, so as to ensure that the one end of the water pipe 520 can be submerged in the condensed water in the water tank 203, thereby ensuring that the pumping system 500 can extract the condensed water.

[0082] like Figures 3 to 6As shown, in some embodiments of the present invention, the water receiving tray 200 is also provided with an overflow groove 204 and an overflow hole 205 connected to the overflow groove 204 , so that the condensed water in the water storage tank 203 can overflow into the overflow groove 204 and flow out from the overflow hole 205 .

[0083] like Figures 4 to 6 As shown, a separation rib 220 is provided on the water receiving tray 200 , and the separation rib 220 extends upward from the bottom wall of the water receiving tray 200 to separate the water storage tank 203 from the overflow tank 204 .

[0084] It is understandable to those skilled in the art that, as the dehumidifier 001 works, more and more condensed water will be condensed by the evaporator 100, thereby making the liquid level in the water storage tank 203 higher and higher.

[0085] When the liquid level in the water storage tank 203 is flush with the top of the dividing rib 220, the condensed water that continues to increase in the water storage tank 203 will flow over the dividing rib 220 to the overflow tank 204, preventing the condensed water from overflowing to the outside.

[0086] In some embodiments of the present invention, the overflow hole 205 is connected to a drain pipe 520 to drain the condensed water through the drain pipe 520 .

[0087] Furthermore, although not shown in the figures, in some embodiments of the present invention, the dehumidifier 001 may also include a water receiving box, which is connected to the drain pipe 520 to receive the condensed water flowing out of the drain pipe 520.

[0088] Furthermore, the water receiving box can be configured to be detachable, so that when the condensed water in the water receiving box is full, the water receiving box can be removed and the condensed water in the water receiving box can be emptied. Then the water receiving box can be installed on the dehumidifier 001.

[0089] like Figure 4 As shown, in some embodiments of the present invention, a drainage hole 206 is provided on the bottom side of the water storage tank 203 so that the user can drain the condensed water in the water storage tank 203 through the drainage hole 206 when the dehumidifier 001 is not in use.

[0090] Therefore, the dehumidifier 001 of the present invention can also prevent water from accumulating in the water storage tank 203 and breeding bacteria when it is not used for a long time.

[0091] Furthermore, although not shown in the drawings, in some embodiments of the present invention, the dehumidifier 001 may also include support wheels to support the dehumidifier 001 to move.

[0092] So far, the technical solution of the utility model has been described in combination with the above multiple embodiments, but it is easy for those skilled in the art to understand that the protection scope of the utility model is not limited to these specific embodiments. Without departing from the technical principle of the utility model, those skilled in the art can split and combine the technical solutions in the above embodiments, and can also make equivalent changes or replacements to the relevant technical features. Any changes, equivalent replacements, improvements, etc. made within the technical concept and / or technical principle of the utility model will fall within the protection scope of the utility model.

[0093] It should be noted that, for the convenience of description and to enable those skilled in the art to quickly understand the technical solution of the utility model, the foregoing only describes the technical features that are strongly related (directly or indirectly related) to the technical problem and / or technical concept to be solved by the utility model, and does not describe the technical features that are weakly related to the technical problem and / or technical concept to be solved by the utility model. Since the technical features with a weaker degree of correlation belong to the common knowledge in the field, even if the utility model does not describe the features with a weaker degree of correlation, it will not lead to insufficient disclosure of the utility model.

[0094] For example, a dehumidifier must include a controller, but since it is common knowledge in the field, the present invention will not elaborate on it.

[0095] Finally, it should be noted that in the present invention, the term "communication" means fluid communication, so as to allow fluid (such as air, liquid) to flow between two connected objects. And the "communication" can be to allow the fluid to flow between the two connected objects without leakage, or to allow the fluid to flow between the two connected objects with a little leakage.
