Description

Technical Field

[0001] The present application relates to the field of integrated ceilings, and in particular to a kitchen and bathroom air conditioner and an integrated ceiling having the air conditioner. Background Art

[0002] In modern home decoration, integrated ceilings have quickly become a popular choice for kitchen and bathroom decoration due to their beautiful appearance, easy installation, and unified style. Integrated ceilings use modular design to perfectly integrate ceiling substrates with multiple functional electrical appliances (such as heating, lighting, and ventilation) to form an integrated ceiling product, which not only enhances the overall aesthetics of the home environment, but also greatly improves the convenience and comfort of use. Against this background, integrated ceilings with integrated kitchen and bathroom air conditioners came into being. This product integrates the air conditioning system into the ceiling, which not only saves space, but also achieves temperature regulation in the kitchen and bathroom space, greatly improving the quality of living.

[0003] The integrated ceiling of the kitchen and bathroom integrated air conditioner is mainly composed of ceiling substrate and functional modules (including air conditioning module, ventilation module, lighting module, etc.). The ceiling substrate is the supporting structure of the entire system, and it can be quickly connected and combined with various functional modules through modular design. The air conditioning module is responsible for regulating the indoor temperature and circulating the air. Condensation water will be generated during the refrigeration process, and the discharge of condensation water often increases the risk of leakage due to problems such as complex pipeline design, difficult installation and easy aging of materials. Summary of the invention

[0004] The purpose of the present application is to provide a kitchen and bathroom air conditioner with reduced risk of water leakage and an integrated ceiling with the air conditioner.

[0005] In the first aspect, the kitchen and bathroom air conditioner provided by this application adopts the following technical solution:

[0006] A kitchen and bathroom air conditioner, comprising:

[0007] The first chamber is provided with a cooling air inlet and a cooling air outlet;

[0008] The second chamber is provided with a circulating air inlet and a circulating air outlet;

[0009] A compressor is used to pressurize and liquefy the refrigerant;

[0010] A condenser, one end of which is connected to the outlet of the compressor and is installed in the first chamber;

[0011] an evaporator, one end of which is connected to the outlet of the condenser and the other end of which is connected to the inlet of the compressor, and is installed in the second chamber;

[0012] A first fan is installed in the first chamber;

[0013] a second fan installed in the second chamber;

[0014] The evaporator is arranged horizontally and located at the upper end of the second chamber. A water collecting tank is arranged below the evaporator, and a water storage tank is arranged above the condenser. The height of the water storage tank is smaller than the height of the water collecting tank, and a connecting pipe is arranged between the two. An opening is opened at the bottom of the water storage tank to allow water in the water storage tank to flow to the surface of the condenser.

[0015] By adopting the above technical solution, the compressor pressurizes and liquefies the refrigerant, and releases heat in the first chamber through the condenser. During this process, the first fan draws air from the cooling air inlet, takes away the heat when passing through the condenser, and discharges it from the cooling air outlet. The evaporator absorbs heat in the second chamber, so that the air entering through the circulating air inlet is cooled, achieving the effect of lowering the temperature of the kitchen and bathroom. In this process, the air may drop below the dew point, thereby condensing condensed water. The condensed water accumulates in the water collection tank and flows into the water storage tank through the connecting pipe. The opening design at the bottom of the water storage tank allows the water to drip evenly and slowly on the surface of the condenser. The latent heat of evaporation of condensed water on the surface of the condenser improves the cooling efficiency of the condenser and further enhances the energy efficiency ratio of the air conditioner.

[0016] Optionally, the compressor is located in the first chamber and on a side of the condenser close to the cooling air inlet.

[0017] By adopting the above technical solution, the compressor will generate a certain amount of heat during operation. Placing it in the first chamber, especially near the cooling air inlet, can effectively use the cold air entering the chamber to perform preliminary cooling on the compressor. This helps to reduce the temperature of the compressor itself, improve its operating efficiency, and extend its service life. On the other hand, it helps to achieve miniaturization of the equipment and efficient use of space.

[0018] Optionally, a water receiving trough is provided at the bottom of the condenser.

[0019] The above technical solution is used to collect unevaporated condensed water.

[0020] Optionally, the condenser includes a solenoid and a heat sink fixedly connected to the solenoid, the solenoid includes a plurality of straight tubes and an elbow that connects the plurality of straight tubes in sequence, the bottom of the heat sink is located in the water receiving tank, and the top of the heat sink is in contact with the water storage tank.

[0021] By adopting the above technical solution, the solenoid structure enables the refrigerant to form a longer flow path when flowing in the tube, thereby increasing the contact time between the refrigerant and the tube wall, thereby improving the heat exchange efficiency.

[0022] Optionally, the surface of the lower end of the heat sink is provided with a capillary liquid structure for lifting condensed water in the water receiving tank to the heat sink.

[0023] By adopting the above technical solution, the capillary liquid extraction structure can effectively lift the condensed water in the water receiving tank to the surface of the heat sink by capillary action. The evaporation of the condensed water on the heat sink will further absorb heat and enhance the heat dissipation effect.

[0024] Optionally, the capillary extract structure is: a fiber layer arranged on the surface of the condenser heat sink; or a fine texture layer formed on the surface of the condenser heat sink by etching or coating.

[0025] By adopting the above technical solution, the fiber layer can quickly absorb the condensed water in the recovery tank due to its porosity and high specific surface area, and keep it inside the fiber layer through capillary action. This design ensures that the condensed water can be continuously and stably supplied to the surface of the heat sink, improving the heat exchange efficiency. The fine texture layer formed on the surface of the heat sink by etching or coating can accurately control the flow path and distribution of the condensed water on the surface of the heat sink.

[0026] Optionally, a vertically arranged dripping tube is fixedly connected to the bottom of the water storage tank, the upper end of the dripping tube is connected to the water storage tank, and the lower end thereof extends to the water collecting tank. The dripping tube is provided with a plurality of drainage holes, and a fiber rope is wrapped around the dripping tube, and the fiber rope is attached to the surface of the heat sink.

[0027] By adopting the above technical solution, the multiple drainage holes on the dripping pipe ensure that the condensed water can flow out of the water storage tank evenly and flow to the water collecting tank through the dripping pipe. At the same time, the fiber rope wrapped around the dripping pipe plays a role in further distributing the condensed water, so that the condensed water can cover the surface of the heat sink more evenly.

[0028] Optionally, the heat sink is formed by stamping to form a protrusion protruding to one side, the protrusion extends vertically, the heat sink is provided with a plurality of flow holes, the flow holes are located at the protrusion position, and the drip tube is located in a groove formed by the stamping of the heat sink.

[0029] By adopting the above technical solution, the convex design increases the surface area of ​​the heat sink, so that the heat exchange area between the heat sink and the air is expanded, which helps to improve the heat exchange efficiency and enhance the heat dissipation effect.

[0030] Optionally, the circulation hole is arranged obliquely, one end of the circulation hole close to the cooling air outlet is higher than the other end, one end of the circulation hole close to the cooling air outlet is located at a raised position, and the other end of the circulation hole is located in a groove formed by stamping protrusion.

[0031] By adopting the above technical solution, when the flowing air passes through the protrusion, a low-pressure area is formed on one side of the protrusion, so that the air on the groove side flows in from the flow hole, flows out from the side of the protrusion, passes through the drip tube and the fiber rope, and as the air on the groove side flows through the flow hole into the low-pressure area on the protrusion side and exchanges heat with the surface of the heat sink, the efficiency of convective heat exchange is significantly improved. This natural airflow circulation ensures that the air can contact the surface of the heat sink more fully and take away more heat.

[0032] On the second aspect, the integrated ceiling with kitchen and bathroom air conditioners provided in the present application adopts the following technical solution: the integrated ceiling includes a keel and a ceiling substrate installed on the keel, the kitchen and bathroom air conditioner is fixedly installed on the keel, and the substrate has two openings, which are respectively connected to the circulating air inlet and the circulating air outlet.

[0033] In summary, the present application includes at least one of the following beneficial technical effects:

[0034] 1. The evaporator absorbs heat in the second chamber, so that the air entering through the circulating air inlet is cooled down to below the dew point, thereby condensing water vapor. The condensed water accumulates in the water collection tank and flows into the water storage tank through the connecting pipe. The opening design at the bottom of the water storage tank allows the water to drip evenly and slowly on the surface of the condenser. The latent heat of evaporation of the condensed water on the surface of the condenser improves the cooling efficiency of the condenser and further enhances the energy efficiency ratio of the air conditioner;

[0035] 2. The surface of the lower end of the heat sink is provided with a capillary liquid structure for lifting the condensed water in the recovery tank to the heat sink. The capillary liquid structure can effectively lift the condensed water in the water receiving tank to the surface of the heat sink by capillary action. The evaporation of the condensed water on the heat sink will further absorb heat and enhance the heat dissipation effect;

[0036] 3. The condensed water drips evenly onto the surface of the heat sink through the drip tube, and is absorbed and distributed by the fiber rope. The inclined flow hole design allows the condensed water to flow naturally to the low-pressure area and evaporate during the flow, thereby improving the evaporation efficiency and taking away more heat.

DETAILED DESCRIPTION

[0046] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0047] Example: Integrated ceiling with kitchen and bathroom air conditioner, refer to Figure 1 The integrated ceiling includes a keel 1 and a ceiling substrate 2 installed on the keel 1, a kitchen and bathroom air conditioner 3 is installed on the keel 1, wherein the ceiling substrate 2 has two openings, and the two openings are respectively connected to the kitchen and bathroom air conditioners 3.

[0048] Reference Figure 2 The kitchen and bathroom air conditioner 3 includes a housing 13, which is divided into two chambers by a partition, namely a first chamber 14 and a second chamber 15. The first chamber 14 is provided with a cooling air inlet 4 and a cooling air outlet 5; the cooling air inlet 4 and the cooling air outlet 5 are respectively located on opposite sides of the housing 13. The second chamber 15 is provided with a circulation air inlet 6 and a circulation air outlet 7, which are respectively located on opposite sides of the housing 13.

[0049] Reference Figure 2 and Figure 3The kitchen and bathroom air conditioner 3 further includes a compressor 8, a condenser 9 and an evaporator 10. One end of the condenser 9 is connected to the outlet of the compressor 8, and the other end is connected to the evaporator 10. The end of the evaporator 10 away from the condenser 9 is connected to the inlet of the compressor 8. The compressor 8 pressurizes and liquefies the refrigerant, and releases heat through the condenser 9. The refrigerant gasifies in the evaporator 10 and absorbs heat, and then returns to the compressor 8.

[0050] Reference Figure 2 The condenser 9 is installed in the first chamber 14, and the first fan 11 is also installed in the first chamber 14. Under the action of the first fan 11, air is sucked in from the cooling air inlet 4, takes away heat when passing through the condenser 9, and is discharged from the cooling air outlet 5.

[0051] The evaporator 10 is installed in the second chamber 15, and the second fan 12 is also installed in the second chamber 15. Under the action of the second fan 12, air enters from the circulating air inlet 6, is cooled when passing through the evaporator 10, and then flows out from the circulating air outlet 7. The circulating air inlet 6 and the circulating air outlet 7 are respectively connected to the two openings on the ceiling substrate 2, and the cooled air enters the kitchen and bathroom, achieving the effect of lowering the temperature of the kitchen and bathroom. The evaporator 10 absorbs heat in the second chamber 15, so that the air entering through the circulating air inlet 6 may be cooled below the dew point during the cooling process, thereby condensing condensed water.

[0052] In order to improve the condensate discharge problem, the following design is carried out:

[0053] The evaporator 10 is disposed horizontally and is located at the upper end of the second chamber 15. The evaporator 10 occupies half of the area of ​​the circulating air inlet 6. A water collecting tank 16 is fixedly installed in the housing 13, and the water collecting tank 16 is located below the evaporator 10.

[0054] A water tank 17 is fixedly installed in the shell 13, and the water tank 17 is located above the condenser 9. The height of the water tank 17 is less than the height of the water collecting tank 16, and a connecting pipe 18 is arranged between the two. An opening is provided at the bottom of the water tank 17 to allow the water in the water tank 17 to flow to the surface of the condenser 9. Condensed water accumulates in the water collecting tank 16 and flows into the water tank 17 through the connecting pipe 18. The opening design at the bottom of the water tank 17 allows the water to drip evenly and slowly on the surface of the condenser 9. The latent heat of evaporation of condensed water on the surface of the condenser 9 improves the cooling efficiency of the condenser 9 and further enhances the energy efficiency ratio of the air conditioner. A water receiving tank 19 is fixedly connected to the bottom of the condenser 9 for collecting unevaporated condensed water.

[0055] Reference Figure 4, the lower position of the circulating air inlet 6 is rotatably connected with a throttle plate 25, and the air intake at the lower position of the circulating air inlet 6 is adjusted by rotating the throttle plate 25. The air entering from the upper position of the circulating air inlet 6 will pass through the evaporator 10, while the air entering from the lower position of the circulating air inlet 6 will not pass through the evaporator 10. The throttle plate 25 is used to adjust the proportion of the circulating air flowing through the evaporator 10. Because the evaporator 10 is arranged horizontally, the path of contact with the air is longer, and this part of the air can be reduced to a lower temperature, and the dehumidification effect of this part of the air is better. The two parts of air flowing into the circulating air inlet 6 will be mixed at the second fan 12 to reach the refrigeration temperature. The proportion of the circulating air flowing through the evaporator 10 is adjusted by the throttle plate 25, thereby adjusting the dehumidification capacity. The housing 13 is equipped with a motor for controlling the rotation of the throttle plate 25, and a plurality of throttle plates 25 are provided. A synchronous wheel is fixedly connected to one end of each throttle plate 25, and the motor drives the synchronous wheel to rotate through a synchronous belt.

[0056] Reference Figure 5 The shell 13 is located in the first chamber 14 and is fixedly connected to a fixing plate 29. The fixing plate 29 is located at one end of the condenser 9 close to the cooling air inlet 4, and a distance is left between the fixing plate 29 and the ground of the first chamber 14. The compressor 8 is installed on the fixing plate 29. Part of the air entering from the cooling air inlet 4 flows through the compressor 8 to cool the compressor 8. Part of the air flows through the condenser 9 from the bottom of the fixing plate 29. There is a space between the top of the condenser 9 and the top of the shell 13. If the heat dissipation area of ​​the condenser 9 is insufficient, two condensers 9 are set. The refrigerant first flows through the condenser 9 close to the cooling air outlet 5, and then flows through the condenser 9 close to the cooling air inlet 4.

[0057] Reference Figure 6 The condenser 9 includes a solenoid 20 and a heat sink 21 fixedly connected to the solenoid 20. The solenoid 20 includes a plurality of straight tubes and an elbow that connects the plurality of straight tubes in sequence. The bottom of the heat sink 21 is located in the water receiving tank 19, and the top of the heat sink 21 is in contact with the water storage tank 17.

[0058] Reference Figure 7 The surface of the lower end of the heat sink 21 is provided with a capillary liquid structure for lifting the condensed water in the water receiving tank 19 to the heat sink 21. The capillary liquid structure can effectively lift the condensed water in the water receiving tank 19 to the surface of the heat sink 21 by capillary action. The evaporation of the condensed water on the heat sink 21 will further absorb heat and enhance the heat dissipation effect.

[0059] The capillary liquid structure is a fiber layer 24 fixedly mounted on the surface of the heat sink 21 of the condenser 9 , or may be a fine texture layer formed on the surface of the heat sink 21 of the condenser 9 by etching or coating.

[0060] Reference Figure 8A plurality of vertically arranged dripping tubes 22 are fixedly connected to the bottom of the water storage tank 17. The upper end of the dripping tube 22 is connected to the opening of the water storage tank 17, and the lower end thereof extends to the water collecting tank 16. A plurality of drainage holes 30 are provided on the side wall of the dripping tube 22. A fiber rope 23 is wound around the dripping tube 22, and the fiber rope 23 is attached to the surface of the heat sink 21, and a portion of the fiber rope 23 extends from the drainage hole into the dripping tube 22. The fiber rope 23 wound around the dripping tube 22 plays a role in further distributing the condensed water, so that the condensed water can be more evenly covered on the surface of the heat sink 21.

[0061] The heat sink 21 is formed by stamping to form a protrusion 26 protruding to one side, and a groove 27 is formed on the other side. The protrusion 26 extends vertically. The heat sink 21 is provided with a plurality of flow holes 28, and the flow holes 28 are arranged obliquely. One end of the flow hole 28 close to the cooling air outlet 5 is higher than the other end. One end of the flow hole 28 close to the cooling air outlet 5 is located at the position of the protrusion 26, and the other end of the flow hole 28 is located in the groove 27 formed by the stamping protrusion. The drip tube 22 is arranged in the groove 27. When the flowing air passes through the protrusion 26, a low-pressure area is formed on one side of the protrusion 26, so that the air on one side of the groove 27 flows in from the flow hole 28, flows out from one side of the protrusion 26, passes through the drip tube 22 and the fiber rope 23, and as the air on one side of the groove 27 flows into the low-pressure area on one side of the protrusion 26 through the flow hole 28, and heat exchanges with the surface of the heat sink 21, the efficiency of convective heat exchange is significantly improved. This natural airflow circulation ensures that the air can more fully contact the surface of the heat sink 21 and take away more heat. The heat sink 21 is provided with a plurality of protrusions 26 and grooves 27 along the direction of air flow, all of which are provided with the above structure.

[0062] The implementation principle of the embodiment of the present application is as follows: the compressor 8 pressurizes and liquefies the refrigerant, and releases heat in the first chamber 14 through the condenser 9. During this process, the first fan 11 inhales air from the cooling air inlet 4, takes away the heat when passing through the condenser 9, and discharges it from the cooling air outlet 5. The evaporator 10 absorbs heat in the second chamber 15, so that the air entering through the circulating air inlet 6 is cooled, achieving the effect of lowering the temperature of the kitchen and bathroom. During this process, the air may drop below the dew point, thereby condensing condensed water. The condensed water accumulates in the water collection tank 16 and flows into the water storage tank 17 through the connecting pipe 18. The multiple drainage holes on the drip tube 22 ensure that the condensed water can flow out of the water storage tank 17 evenly, and the fiber rope 23 wrapped around the drip tube 22 plays a role in further distributing the condensed water, so that the condensed water can be more evenly covered on the surface of the heat sink 21. The unevaporated condensed water accumulates in the water collection tank 16, and the capillary extraction structure can effectively lift the condensed water in the water receiving tank 19 to the surface of the heat sink 21 by capillary action. The evaporation of condensed water on the heat sink 21 will further absorb heat and enhance the heat dissipation effect.
