Description

Technical Field

[0001] The utility model relates to the technical field of air conditioners, and specifically, to a water receiving tray assembly and an air conditioner. Background Art

[0002] In real life, air conditioners are essential household appliances. After the evaporator inside the indoor unit of the air conditioner exchanges heat with indoor water vapor, the water vapor condenses into condensed water at a temperature lower than the dew point temperature. Its principle is similar to that of distilled water. According to the working principle of the air conditioner, the air conditioner cools the indoor air, and the water vapor in the indoor air liquefies into condensed water under the action of the cold air. The current condensed water is discharged from the condensate pipe of the air conditioner under the action of gravity. Due to the air conditioner working day and night and the accumulation of dust over time, it is very easy for the condensed water to backflow due to partial blockage of the condensate pipe on windy and rainy days. Summary of the Utility Model

[0003] The first object of the utility model is to provide a water receiving tray assembly that solves the problem of backflow of condensed water caused by the dust blockage of the condensate pipe of the air conditioner and the failure of the condensed water to be discharged in time.

[0004] The second object of the utility model is to provide an air conditioner that adopts the above water receiving tray assembly.

[0005] To achieve the above first object, the utility model provides a water receiving tray assembly, including: a water receiving tray body, a water receiving groove is arranged inside the water receiving tray body, and a water outlet is opened on the bottom wall of the water receiving groove; a condensate pipe, the condensate pipe is located outside the water receiving groove, one end of the condensate pipe is connected to the water outlet, and the water receiving groove is communicated with the condensate pipe through the water outlet; the water receiving tray assembly further includes: an electromagnet, the electromagnet is arranged on the water receiving tray body and close to the water outlet; a sealing plug, at least a part of the sealing plug is made of ferromagnetic material, the sealing plug is arranged at the water outlet and can move in the vertical direction to open or close the water outlet; a water level sensor, the water level sensor is arranged inside the water receiving groove; the electromagnet can apply an upward attraction force to the sealing plug to force the sealing plug to open the water outlet; after the electromagnet cancels the attraction force applied to the sealing plug, the sealing plug can fall and close the water outlet at least under the action of its own gravity.

[0006] As can be seen from the above solution, by setting a sealing plug and an electromagnet for driving the movement of the sealing plug at the water outlet, in the initial state, the electromagnet is in a power-off state, and the sealing plug closes the water outlet. When the water level sensor detects that the water level in the water receiving tank reaches the first preset water level, after the electromagnet is powered on, it attracts the sealing plug to move upward, thereby opening the water outlet. The condensed water in the water receiving tank flows rapidly towards the water outlet under the action of its own gravity and takes away the dust and impurities in the water receiving tank. Since the interface is instantaneously conducted, the condensed water flows out rapidly under the action of its own gravity. According to the momentum theorem, the momentum at this time is sufficient to carry the impurities out of the condensate pipe and can effectively prevent the condensate pipe from being blocked. After the condensed water in the water receiving tank is discharged, the electromagnet is powered off, and the sealing plug falls under the action of its own gravity and closes the water outlet. Therefore, the water receiving tray assembly of the present invention solves the problem of condensate backflow caused by the dust blockage of the air conditioner condensate pipe and the failure of the condensed water to be discharged in time.

[0007] A preferred solution is that the water receiving tray assembly further includes a guiding sleeve. The electromagnet is arranged at the top end of the guiding sleeve, and the water outlet is located at the bottom end of the guiding sleeve; the sealing plug is slidably matched with the guiding sleeve, and the length of the guiding sleeve is greater than the height of the sealing plug; a communication port is provided on the side wall of the guiding sleeve, and the water outlet is communicated with the water receiving tank through the communication port; or the guiding sleeve is fixed to the electromagnet, and a communication port is formed between the lower end wall of the guiding sleeve and the bottom wall of the water receiving tank, and the water outlet is communicated with the water receiving tank through the communication port.

[0008] It can be seen that the guiding sleeve is used to guide the movement of the sealing plug to prevent the sealing plug from being misaligned when falling and unable to close the water outlet.

[0009] A further solution is that the inner diameter of the guiding sleeve remains unchanged from the top end to the bottom end; or the inner diameter of the guiding sleeve gradually decreases from the top end to the bottom end.

[0010] It can be seen that the inner wall of the guiding sleeve can be cylindrical or frustum-shaped to achieve good guiding of the sealing plug. At the same time, the frustum-shaped setting can reduce the friction between the sealing plug and the guiding sleeve during the upward movement of the sealing plug, so that the sealing plug can open the water outlet faster.

[0011] A further solution is that the number of communication ports is two or more, and the multiple communication ports are arranged at intervals along the circumferential direction of the guiding sleeve.

[0012] It can be seen that the setting of multiple communication ports can enable more water to enter the water outlet through the communication ports, and the water outlet is subjected to a greater impact force of the water flow, thereby avoiding blockage of the water outlet.

[0013] A preferred solution is that the height of the sealing plug is 3 / 4 of the length of the guiding sleeve.

[0014] Preferably, when the sealing plug is in the position of closing the water outlet, there is a sealing fit between the outer peripheral wall of the sealing plug and the inner peripheral wall of the water outlet.

[0015] Thus, it can prevent water leakage when the sealing plug is in the position of closing the water outlet.

[0016] Preferably, the water receiving tray assembly further includes an elastic reset member, and two ends of the elastic reset member are respectively connected to the electromagnet and the sealing plug; under the action of the elastic restoring force of the elastic reset member, the sealing plug moves towards the direction of the water outlet.

[0017] Thus, the elastic reset member can assist the sealing plug to move towards the water outlet, and at the same time can prevent the sealing plug from moving out of position.

[0018] Preferably, the water outlet is arranged close to the side wall of the water receiving tray body, and the electromagnet is fixed on the side wall of the water receiving tray body.

[0019] Thus, the electromagnet can be directly fixed to the top wall of the side wall of the water receiving tray body without setting additional fixing components.

[0020] Preferably, the bottom wall of the water receiving groove is inclined towards the water outlet.

[0021] Thus, the inclined bottom wall of the water receiving groove can make the condensed water in the water receiving groove move towards the water outlet under its own gravity, ensure that the condensed water in the water receiving groove is emptied, and prevent the remaining condensed water from breeding bacteria, etc.

[0022] To achieve the above second object, the present utility model provides an air conditioner, which includes a heat exchanger and the above-mentioned water receiving tray assembly, and the heat exchanger is arranged above the water receiving tray assembly. Description of the Drawings

[0031] Techniques, methods and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the techniques, methods and devices should be regarded as part of the specification.

[0032] See Figures 1 to 3 , the air conditioner of this embodiment includes a heat exchanger and a water receiving tray assembly 1, and the heat exchanger is arranged above the water receiving tray assembly 1.

[0033] The water receiving tray assembly 1 includes a water receiving tray body 2, a condensate water pipe 3, a water level sensor, an electromagnet 4, a sealing plug 5 and a guide sleeve 6.

[0034] A water receiving tray body 2 is provided with a water receiving groove 21. A water outlet 22 is formed in the bottom wall of the water receiving groove 21. A condensation water pipe 3 is located outside the water receiving groove 21 of the water receiving tray body 2. One end of the condensation water pipe 3 is connected to the water outlet 22. The water receiving groove 21 and the condensation water pipe 3 are communicated through the water outlet 22. A water level sensor is arranged in the water receiving groove 21 and is used for detecting the water level of the condensation water in the water receiving groove 21.

[0035] An electromagnet 4 is arranged on the water receiving tray body 2 and is arranged close to the water outlet 22. At least a part of a sealing plug 5 is made of a ferromagnetic material. The sealing plug 5 is arranged at the water outlet 22 and can move in the vertical direction to open or close the water outlet 22. The electromagnet 4 can apply an upward attractive force to the sealing plug 5 to force the sealing plug 5 to open the water outlet 22. In addition, after the electromagnet 4 cancels the attractive force applied to the sealing plug 5, the sealing plug 5 can fall at least under the action of its own gravity and close the water outlet 22. In this embodiment, during the falling process of the sealing plug 5, the sealing plug 5 is not only affected by its own gravity, but also affected by the elastic restoring force of an elastic resetting member 7.

[0036] The electromagnet 4 is arranged at the top end of a guiding sleeve 6. The water outlet 22 is located at the bottom end of the guiding sleeve 6. The sealing plug 5 is in sliding fit with the guiding sleeve 6, and the sealing plug 5 is in clearance fit with the guiding sleeve 6. The length of the guiding sleeve 6 is greater than the height of the sealing plug 5. Preferably, the height of the sealing plug 5 is 3 / 4 of the length of the guiding sleeve 6. When the sealing plug 5 is in the position of closing the water outlet 22, a sealing fit is formed between the outer peripheral wall of the sealing plug 5 and the inner peripheral wall of the water outlet 22 to prevent water leakage.

[0037] From the top end to the bottom end, the inner diameter of the guiding sleeve 6 remains unchanged, that is, the guiding sleeve 6 is in the shape of a cylindrical tube to achieve good guiding of the sealing plug 5. A communication port (not shown) is formed in the side wall of the guiding sleeve 6. The water outlet 22 and the water receiving groove 21 are communicated through the communication port. The number of the communication ports is more than two, and a plurality of communication ports are arranged at intervals along the circumferential direction of the guiding sleeve 6. The arrangement of the plurality of communication ports can enable more water to enter the water outlet 22 through the communication ports, and the water outlet 22 is subjected to a greater impact force of the water flow, thereby avoiding blockage of the water outlet 22.

[0038] The water receiving tray assembly 1 further includes an elastic resetting member 7. Two ends of the elastic resetting member 7 are respectively connected to the electromagnet 4 and the sealing plug 5. The sealing plug 5 can move towards the water outlet 22 under the action of its own gravity and the elastic restoring force of the elastic resetting member 7. At the same time, the elastic resetting member 7 can prevent the sealing plug 5 from moving out of position.

[0039] The water outlet 22 is arranged close to the corner of the water receiving tray body 2. The electromagnet 4 is fixed on two adjacent side walls of the water receiving tray body 2. In this way, the electromagnet 4 can be directly fixed to the top wall of the side wall of the water receiving tray body 2 without additionally arranging fixing components.

[0040] The bottom wall of the water receiving tank 21 is inclined towards the water outlet 22. The inclined bottom wall of the water receiving tank 21 enables the condensed water in the water receiving tank 21 to move towards the water outlet 22 under its own gravity, ensuring that the condensed water in the water receiving tank 21 is emptied and preventing the remaining condensed water from breeding bacteria and the like.

[0041] By providing a sealing plug 5 at the position of the water outlet 22 and an electromagnet 4 for driving the movement of the sealing plug 5, in the initial state, the electromagnet 4 is in a power-off state, and the sealing plug 5 closes the water outlet 22. When the water level sensor detects that the water level in the water receiving tank 21 reaches the first preset water level, after the electromagnet 4 is powered on, it attracts the sealing plug 5 to move upward along the guiding sleeve 6, thereby opening the water outlet 22. The condensed water in the water receiving tank 21, under the action of its own gravity, quickly flows towards the water outlet 22 and takes away the dust and impurities in the water receiving tank 21. Since the interface is instantaneously conducted, the condensed water quickly flows out under the action of its own gravity. According to the momentum theorem, the momentum at this time is sufficient to carry the impurities out of the condensate pipe 3 and can effectively prevent the condensate pipe 3 from being blocked. After the condensed water in the water receiving tank 21 is drained, the electromagnet 4 is powered off, and the sealing plug 5 falls under its own gravity and closes the water outlet 22. Therefore, the water receiving tray assembly 1 of the present invention solves the problem of condensate backflow caused by the dust blockage of the air conditioner condensate pipe 3 and the failure of the condensed water to be discharged in time.

[0042] In addition, from the top to the bottom, the inner diameter of the guiding sleeve can also gradually decrease, that is, the inner wall of the guiding sleeve can also be frustum-shaped, which can reduce the friction between the sealing plug and the guiding sleeve during the upward movement of the sealing plug, so that the sealing plug can open the water outlet faster. The sealing plug can also be entirely made of ferromagnetic material, and an annular sealing ring is sleeved on the peripheral wall of the end of the sealing plug close to the water outlet to ensure that the sealing plug can tightly block the water outlet and prevent water leakage. The water receiving tray assembly can also not include an elastic resetting member, and the sealing plug only falls under its own gravity and blocks the water outlet. The sealing plug can be cylindrical or prismatic, etc., and the specific shape and size can be changed according to needs. The condensate pipe and the guiding sleeve can be integrally formed or can be a split structure. When it is a split structure, the two can be butted at the position of the water outlet, or the two can also be arranged at a certain distance. The guiding sleeve can be in contact with the bottom wall of the water receiving tray body, and the communication port is formed on the peripheral wall of the guiding sleeve. The guiding sleeve can also not be in contact with the bottom wall of the water receiving tray body, and the communication port is located between the end wall of the guiding sleeve and the water receiving tray body. The guiding sleeve is fixed on the electromagnet. The water outlet can also be arranged close to a side wall of the water receiving tray body instead of being arranged at a corner position. The above changes can also achieve the purpose of the present utility model.

[0043] Finally, it should be emphasized that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
