Description

Technical Field

[0001] The utility model relates to an air-conditioning range hood. Background Art

[0002] Range hoods are typically wall-mounted. During cooking, they generate significant heat, raising the temperature in the kitchen and reducing the user experience. To mitigate this problem, traditional range hoods are integrated with cooling modules to create air-conditioned range hoods. This cooling module lowers the temperature in the kitchen, improving user comfort and enhancing the user experience.

[0003] At present, the condensed water generated by the refrigeration module of the air-conditioning range hood on the market is usually discharged externally. Specifically, the condensed water condensed on the evaporator is collected in a water receiving tray and flows to the outside through a pipe with a certain slope.

[0004] However, the method of discharging condensed water causes long-term erosion of the user's external walls and dripping in the external environment. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide an air-conditioning range hood in order to overcome the defects of the prior art in which the condensed water is discharged, causing long-term erosion of the user's external wall and dripping in the external environment.

[0006] The utility model solves the above technical problems through the following technical solutions:

[0007] An air-conditioned range hood includes a housing, an air-conditioning assembly is installed in the housing, the air-conditioning assembly includes a compressor, a condenser, and an evaporator, the compressor, condenser, and evaporator are connected by a refrigerant pipeline, and the characteristics are:

[0008] The condensed water condensed on the evaporator is collected and transported to the top of the condenser through a water supply channel, so that the condensed water exchanges heat with the condenser and evaporates. The water outlet of the water supply channel is arranged near the top of the condenser on the most upstream side along the flow direction of the heat dissipation airflow, and the flow direction forms a non-zero angle with the vertical direction.

[0009] The condenser includes multiple rows of heat exchange tube groups and multiple heat exchange fins. The multiple rows of heat exchange tube groups are arranged at intervals along the flow direction. Each row of the heat exchange tube groups includes multiple heat exchange tubes arranged along the vertical direction and connected in sequence. The multiple heat exchange fins are arranged at intervals along the vertical direction, and each heat exchange fin is arranged in the horizontal direction.

[0010] Each of the heat exchange fins includes a first part and a second part along the horizontal direction, the first part is arranged outside the heat exchange tube group in a row farthest from the water outlet of the water supply channel, and the second part is arranged outside the remaining heat exchange tube groups, and there is a first non-zero spacing between the first part and the second part along the flow direction of the heat dissipation airflow.

[0011] In the present technical solution, a water supply channel is provided to transport the condensed water condensed on the evaporator to the top of the condenser, so that the condensed water is evaporated by heat exchange with the condenser, thereby eliminating the need to discharge the condensed water, thereby avoiding the erosion of the user's external wall by the condensed water and the risk of dripping in the external environment. In addition, the condensation effect of the condenser is improved by utilizing the heat exchange evaporation of the condensed water. Furthermore, by limiting the specific arrangement of the multiple rows of heat exchange tube groups and the multiple heat exchange fins of the condenser, and providing a non-zero first spacing between the first part and the second part of the heat exchange fins along the flow direction of the heat dissipation airflow, in the process of the condensed water diffusing horizontally and flowing downward along the heat exchange fins, the condensed water flowing to the second part of the heat exchange fins can be effectively prevented from flying out, thereby effectively preventing the condensed water from being blown away to other locations due to the excessive air volume of the heat dissipation airflow (i.e., heat dissipation air).

[0012] Preferably, the first spacing is 3 mm to 5 mm.

[0013] In this technical solution, by setting the value range of the first spacing, the first spacing is prevented from being too small, which will fail to prevent the condensed water from being blown away by the wind and flowing to other locations; and if the first spacing is too large, the overall structure of the condenser will be too large, and the overall space occupied by the air-conditioning range hood will be too large.

[0014] Preferably, along the vertical direction, there is a second non-zero distance between the water outlet of the water delivery channel and the top of the condenser.

[0015] In this technical solution, by setting a second non-zero distance between the water outlet of the water supply channel in the vertical direction and the top of the condenser, the condensed water can flow smoothly from the water outlet of the water supply channel to the top of the condenser.

[0016] Preferably, the condenser further comprises a first side plate and a second side plate, wherein the first side plate is located above the plurality of heat exchange fins along the vertical direction, and the second side plate is located below the plurality of heat exchange fins along the vertical direction, and both the first side plate and the second side plate have fixing holes for passing the plurality of heat exchange tube groups, and a gap is formed between the outer wall of each heat exchange tube and the inner wall of the corresponding fixing hole;

[0017] There is the second distance between the water outlet of the water delivery channel and the upper surface of the first side plate along the vertical direction.

[0018] In the present technical solution, a specific setting method of the condenser is provided, and by setting a second distance between the water outlet of the water supply channel in the vertical direction and the upper surface of the first side plate, the condensed water can flow smoothly from the water outlet of the water supply channel to the upper surface of the first side plate of the condenser, and then flow into the position of multiple heat exchange fins through the gap between the outer wall of the heat exchange tube and the inner wall of the corresponding fixing hole.

[0019] Preferably, the second spacing is 5 mm to 10 mm.

[0020] In this technical solution, by setting the value range of the second spacing, the second spacing is prevented from being too small to block the flow of condensed water; and if the second spacing is too large, the condensed water cannot accurately flow to the top of the condenser.

[0021] Preferably, the condenser includes a first welding portion connecting the inlet of multiple rows of heat exchange tube groups and the water inlet joint, and a second welding portion connecting the outlet of multiple rows of heat exchange tube groups and the water outlet joint. The first welding portion and the second welding portion are both located at the top of the condenser, and the plane where the bottom surface of the first welding portion and the second welding portion is located is higher than the plane where the water outlet of the water transfer channel is located along the vertical direction.

[0022] In this technical solution, by arranging the first welding part and the second welding part to be located at the top of the condenser, and the plane where the bottom surfaces of the first welding part and the second welding part are located is higher than the plane where the water outlet of the water supply channel is located in the vertical direction, the first welding part and the second welding part can be prevented from being corroded by condensed water too quickly.

[0023] Preferably, the air-conditioning range hood also includes a water storage box and a water pump installed in the water storage box, the water supply channel connects the water storage box and the top of the condenser, and the water pump is located at the end of the water supply channel close to the water storage box; the water storage box is used to collect condensed water condensed on the surface of the evaporator; the water pump is used to pump the condensed water in the water storage box to the top of the condenser through the water supply channel.

[0024] In this technical solution, a water storage box is provided to collect condensed water condensed on the surface of the evaporator; and a water pump is provided to pump the condensed water in the water storage box to the top of the condenser through the water delivery channel.

[0025] Preferably, the air conditioning component also includes a heat dissipation fan, which is arranged corresponding to the condenser. When the heat dissipation fan is working, the heat dissipation airflow is formed, and the inlets of the multiple rows of heat exchange tube groups are located downstream of the outlets of the multiple rows of heat exchange tube groups along the flow direction of the heat dissipation airflow.

[0026] In the present technical solution, a heat dissipation fan is provided to realize the condensation effect of the condenser by air cooling; further, the inlet of the multiple rows of heat exchange tube groups is provided downstream of the outlet of the multiple rows of heat exchange tube groups along the flow direction of the heat dissipation airflow, so that the condenser and the flow direction of the heat dissipation air are in countercurrent heat exchange, thereby effectively improving the heat exchange efficiency of the condenser.

[0027] Preferably, the condenser is located in the shell of the heat dissipation fan, and the air-conditioning range hood further includes a water return channel, which connects the bottom of the shell and the water storage box, and the condensed water that has not been evaporated is collected at the bottom of the shell.

[0028] In this technical solution, a return water channel is set up to connect the bottom of the shell and the water storage box to recover the unevaporated condensed water to the water storage box, so that the condensed water can be transported to the top of the condenser for the next round of heat exchange evaporation.

[0029] Preferably, the air-conditioning range hood further comprises a range hood assembly, a range hood fan of the range hood assembly is located in the casing, and an outlet of the heat dissipation fan is connected to an inner cavity of a volute of the range hood fan.

[0030] In this technical solution, by setting the outlet of the heat dissipation fan to be connected to the inner cavity of the volute of the range hood fan, the wind passing through the condenser can be discharged to the public flue through the range hood volute and the smoke pipe without the need to set up a separate exhaust pipeline, thereby achieving the beneficial technical effect of simplifying the structure.

[0031] The positive progress effect of this utility model is:

[0032] By setting up a water supply channel to transport the condensed water condensed on the evaporator to the top of the condenser, the condensed water is evaporated by heat exchange with the condenser, so that there is no need to discharge the condensed water, thereby avoiding the erosion of the user's external wall by the condensed water and the risk of dripping in the external environment. In addition, by being able to utilize the heat exchange and evaporation of the condensed water, the condensation effect of the condenser is improved; further, by limiting the specific setting method of the multiple rows of heat exchange tube groups and the multiple heat exchange fins of the condenser, and the first part and the second part of the heat exchange fins having a non-zero first spacing along the flow direction of the heat dissipation airflow, in the process of the condensed water diffusing horizontally and flowing downward along the heat exchange fins, the condensed water flowing to the second part of the heat exchange fins can be effectively prevented from flying out, thereby effectively preventing the condensed water from being blown away to other locations due to the excessive air volume of the heat dissipation airflow (i.e., heat dissipation air).

[0073] The following describes in detail embodiments of the present invention, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions.

[0075] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0076] like Figures 1 to 6 As shown, this embodiment provides an air-conditioned range hood 1. The air-conditioned range hood 1 comprises a range hood assembly 10 and an air-conditioning assembly 20, wherein the range hood assembly 10 is used to realize the oil fume suction function; and the air-conditioning assembly 20 is used to realize the air-conditioning function.

[0077] The air-conditioning range hood 1 further includes a housing 30, and the air-conditioning assembly 20 is installed in the housing 30. It should be noted that in order to better illustrate the structure of the components located inside the housing 30, Figure 1 What is shown in FIG. 3 is the internal structure of the housing 30 .

[0078] The air conditioning assembly 20 includes a compressor 21 , a condenser 22 and an evaporator 23 , and the compressor 21 , the condenser 22 and the evaporator 23 are connected via a refrigerant pipeline.

[0079] Condensed water condensed on the evaporator 23 is collected and transported to the top of the condenser 22 via a water supply channel 41, where it is evaporated by heat exchange with the condenser 22. The water outlet 411 of the water supply channel 41 is located near the top of the condenser 22, at the most upstream side along the flow direction F of the heat dissipation airflow. The flow direction F forms a non-zero angle with the vertical direction H. Thus, by providing a water supply channel 41 that transports the condensed water condensed on the evaporator 23 to the top of the condenser 22, the condensed water is evaporated by heat exchange with the condenser 22, eliminating the need for condensed water external discharge, avoiding condensed water corrosion on the user's exterior walls and the risk of dripping into the external environment. Furthermore, by utilizing the heat exchange and evaporation of the condensed water, the condensation efficiency of the condenser 22 is improved. The flow direction F forms a non-zero angle with the vertical direction H, meaning that the heat dissipation airflow enters the condenser 22 from one side of the condenser 22, rather than from the top or bottom of the condenser 22.

[0080] Furthermore, the condenser 22 includes multiple rows of heat exchange tube groups 221 and multiple heat exchange fins 222. The multiple rows of heat exchange tube groups 221 are arranged at intervals along the flow direction F. Each row of heat exchange tube groups 221 includes multiple heat exchange tubes 2211 arranged along the vertical direction H and connected in sequence. The multiple heat exchange fins 222 are arranged at intervals along the vertical direction H, and each heat exchange fin 222 is arranged along the horizontal direction O. Each heat exchange fin 222 includes a first portion 2221 and a second portion 2222 along the horizontal direction O. The first portion 2221 is mounted outside the row of heat exchange tube groups 221 farthest from the water outlet 411 of the water supply channel 41, and the second portion 2222 is mounted outside the remaining heat exchange tube groups 221. A non-zero first spacing D1 is defined between the first portion 2221 and the second portion 2222 along the flow direction F of the heat dissipation airflow. Thus, by defining the specific arrangement of the multiple rows of heat exchange tube groups 221 and the multiple heat exchange fins 222 of the condenser 22, and by providing a non-zero first spacing D1 between the first portion 2221 and the second portion 2222 of the heat exchange fins 222 along the flow direction F of the heat dissipation airflow, condensate flowing into the second portion 2222 of the heat exchange fins 222 can be effectively prevented from flying out during the process of condensate diffusing and flowing downward in the horizontal direction O along the heat exchange fins 222, thereby effectively preventing condensate from being blown away to other locations due to excessive heat dissipation airflow (i.e., heat dissipation air). The first portion 2221 is mounted outside the row of heat exchange tube groups 221 farthest from the water outlet 411 of the water supply channel 41, and the second portion 2222 is mounted outside the remaining heat exchange tube groups 221. In other words, the second portion 2222 of the heat exchange fins 222 is located upstream of the first portion 2221 along the flow direction F.

[0081] It should be noted that the water outlet 411 of the water supply channel 41 is positioned near the uppermost upstream side of the top of the condenser 22 along the flow direction F of the heat dissipation airflow. This allows the condensed water to diffuse along the flow direction F of the heat dissipation airflow as it diffuses horizontally O and flows downward from the heat exchange fins 222. As a result, the condensed water encounters the gap formed by the first spacing D1 between the first portion 2221 and the second portion 2222, preventing it from flowing into the first portion 2221. Furthermore, the water outlet 411 of the water supply channel 41 is positioned in the middle of the uppermost upstream side of the top of the condenser 22, allowing the condensed water to diffuse evenly downward.

[0082] Specifically, in this embodiment, the number of rows of heat exchange tube groups 221 is two, and the first portion 2221 of the heat exchange fins 222 is sleeved outside the row of heat exchange tube groups 221 farthest from the water outlet 411 of the water delivery channel 41. In other words, the first portion 2221 of the heat exchange fins 222 is sleeved outside the row of heat exchange tube groups 221 farthest from the water outlet 411 of the water delivery channel 41. Figures 1 to 3The second portion 2222 of the heat exchange fin 222 is sleeved outside the remaining heat exchange tube group 221, that is, the second portion 2222 of the heat exchange fin 222 is sleeved outside the remaining heat exchange tube group 221. Figures 1 to 3 The heat exchange tube group 221 on the right side of the middle. However, in another embodiment of the pump embodiment, Figure 7 As shown, the number of rows of heat exchange tube groups 221 is three, and the first portion 2221 of the heat exchange fins is sleeved outside the row of heat exchange tube groups 221 farthest from the water outlet 411 of the water delivery channel 41. That is, the first portion 2221 of the heat exchange fins 222 is sleeved outside the row of heat exchange tube groups 221 farthest from the water outlet 411 of the water delivery channel 41. Figure 7 The second portion 2222 of the heat exchange fin 222 is sleeved outside the remaining heat exchange tube group 221, that is, the second portion 2222 of the heat exchange fin 222 is sleeved outside the remaining heat exchange tube group 221. Figure 7 Outside the two rows of heat exchange tube groups 221 on the middle right.

[0083] Preferably, the first distance D1 is 3 mm to 5 mm. Thus, by setting the range of the first distance D1, it is prevented that the first distance D1 is too small, thereby failing to prevent the condensed water from being blown away by the wind and flowing to other locations; and that the first distance D1 is too large, thereby causing the overall structure of the condenser 22 to be too large, resulting in the air conditioner range hood 1 occupying too much space.

[0084] A non-zero second spacing D2 is provided between the water outlet 411 of the water supply channel 41 and the top of the condenser 22 along the vertical direction H. Thus, by providing a non-zero second spacing D2 between the water outlet 411 of the water supply channel 41 and the top of the condenser 22 along the vertical direction H, condensed water can flow smoothly from the water outlet 411 of the water supply channel 41 to the top of the condenser 22.

[0085] Specifically, the condenser 22 further includes a first side plate 223 and a second side plate 224. The first side plate 223 is positioned above the plurality of heat exchange fins 222 along the vertical direction H, and the second side plate 224 is positioned below the plurality of heat exchange fins 222 along the vertical direction H. Both the first side plate 223 and the second side plate 224 have fixing holes for the plurality of heat exchange tube groups 221 to pass through, and a gap is defined between the outer wall of each heat exchange tube 2211 and the inner wall of the corresponding fixing hole. This provides a specific configuration for the condenser 22. By providing a second distance D2 between the water outlet 411 of the water supply channel 41 and the upper surface of the first side plate 223 along the vertical direction H, condensed water can flow smoothly from the water outlet 411 of the water supply channel 41 to the upper surface of the first side plate 223 of the condenser 22, and then flow through the gap between the outer wall of the heat exchange tube 2211 and the inner wall of the corresponding fixing hole to the position of the plurality of heat exchange fins 222.

[0086] A second distance D2 is defined between the water outlet 411 of the water delivery channel 41 and the upper surface of the first side plate 223 along the vertical direction H. Preferably, the second distance D2 is between 5 mm and 10 mm. By setting a range of values for the second distance D2, it is possible to prevent the second distance D2 from being too small, thereby blocking the flow of condensed water, and from being too large, thereby preventing the condensed water from accurately flowing to the top of the condenser 22.

[0087] In this embodiment, the air conditioning range hood 1 further includes a water storage box 42 and a water pump 43 installed in the water storage box 42. A water supply channel 41 connects the water storage box 42 with the top of the condenser 22, and the water pump 43 is located at the end of the water supply channel 41 near the water storage box 42. The water storage box 42 is used to collect condensed water condensed on the surface of the evaporator 23. The water pump 43 is used to pump the condensed water in the water storage box 42 to the top of the condenser 22 through the water supply channel 41. In this way, the water storage box 42 is provided to collect condensed water condensed on the surface of the evaporator 23, and the water pump 43 is provided to pump the condensed water in the water storage box 42 to the top of the condenser 22 through the water supply channel 41.

[0088] Air conditioning assembly 20 also includes a cooling fan 24, which is positioned corresponding to condenser 22. When operating, cooling fan 24 generates a cooling airflow. The inlets of the two rows of heat exchange tubes 221 are located downstream of the outlets of the two rows of heat exchange tubes 221 along the flow direction F of the cooling airflow. Thus, by providing cooling fan 24, condensation in condenser 22 is achieved through air cooling. Furthermore, by positioning the inlets of the two rows of heat exchange tubes 221 downstream of the outlets of the two rows of heat exchange tubes 221 along the flow direction F of the cooling airflow, heat exchange between condenser 22 and the cooling airflow is countercurrent, effectively improving the heat exchange efficiency of condenser 22. This is because the temperature of the refrigerant on the side close to the inlet 2212 of the two rows of heat exchange tube groups 221 is higher than the temperature of the refrigerant on the side close to the outlet 2213 of the two rows of heat exchange tube groups 221. After the heat dissipation airflow is first blown to the side of the outlet 2213 of the two rows of heat exchange tube groups 221 with lower temperature for heat exchange, the temperature increase of the heat dissipation airflow itself is relatively low. These heat dissipation airflows can continue to exchange heat when blown to the side of the inlet 2212 of the two rows of heat exchange tube groups 221 with higher temperature, thereby effectively improving the heat exchange efficiency of the condenser.

[0089] The condenser 22 includes a first welded portion connecting the inlet 2212 of the multiple rows of heat exchange tubes 221 with the water inlet joint, and a second welded portion connecting the outlet 2213 of the multiple rows of heat exchange tubes 221 with the water outlet joint. The first welded portion and the second welded portion are both located at the top of the condenser 22, and the bottom surfaces of the first welded portion and the second welded portion are located in a plane higher than the plane of the water outlet 411 of the water supply channel 41 along the vertical direction H. Thus, the first welded portion and the second welded portion are both located at the top of the condenser 22, and the bottom surfaces of the first welded portion and the second welded portion are located in a plane higher than the plane of the water outlet 411 of the water supply channel 41 along the vertical direction H, thereby preventing the first welded portion and the second welded portion from being corroded too quickly by condensed water.

[0090] In this embodiment, the heat exchange tubes 2211 are U-shaped tubes. Adjacent heat exchange tubes 2211 are connected via U-shaped joints 226 , and the U-shaped joints 226 are located above the first side plate 223 .

[0091] The condenser 22 is located within the housing of the heat dissipation fan 24. The air conditioning range hood 1 also includes a water return channel 44, which connects the bottom of the housing and the water storage box 42. Unevaporated condensed water is collected at the bottom of the housing. Thus, by providing a water return channel 44 connecting the bottom of the housing and the water storage box 42, unevaporated condensed water is recovered to the water storage box 42, making it easier to later transport this condensed water to the top of the condenser 22 for the next round of heat exchange and evaporation.

[0092] The range hood assembly 10 includes a range hood fan 11, which is located within the housing 30. The outlet of the heat dissipation fan 24 communicates with the inner cavity of the volute of the range hood fan 11. By connecting the outlet of the heat dissipation fan 24 to the inner cavity of the volute of the range hood fan 11, the heat dissipation airflow passing through the condenser 22 can be discharged into a common flue through the range hood volute and the flue pipe, eliminating the need for a separate exhaust pipeline. This achieves the beneficial technical effect of simplifying the structure.

[0093] The range hood assembly 10 further includes a hood 12 , which is located below the housing 30 . The hood 12 is provided with an air inlet cavity connected to the range hood fan 11 , and an air inlet is provided on a side of the air inlet cavity away from the housing 30 .

[0094] The air conditioning assembly 20 also includes an indoor fan 25, which is positioned corresponding to the evaporator 23 and is used to blow the air after heat exchange with the evaporator 23 out of the housing 30 of the air conditioning range hood 1. An air outlet 26 connected to the indoor fan 25 is formed on the end of the hood 12 near the housing 30, facing the user.

[0095] In this embodiment, a water supply channel 41 is provided to transport the condensed water condensed on the evaporator 23 to the top of the condenser 22, so that the condensed water exchanges heat with the condenser 22 and evaporates, thereby eliminating the need to discharge the condensed water, avoiding the risk of erosion of the user's external wall by the condensed water and dripping in the external environment. In addition, by utilizing the heat exchange evaporation of the condensed water, the condensation effect of the condenser 22 is improved. Furthermore, by limiting the specific arrangement of the multiple rows of heat exchange tube groups 221 and the multiple heat exchange fins 222 of the condenser 22, and providing a non-zero first spacing D1 between the first part 2221 and the second part 2222 of the heat exchange fin 222 along the flow direction F of the heat dissipation airflow, in the process of the condensed water diffusing and flowing downward along the heat exchange fin 222 in the horizontal direction O, the condensed water flowing to the second part 2222 of the heat exchange fin 222 can be effectively prevented from flying out, thereby effectively preventing the condensed water from being blown away to other locations due to excessive air volume of the heat dissipation airflow (i.e., heat dissipation air).

[0096] Although specific embodiments of the present invention have been described above, those skilled in the art will appreciate that these are merely illustrative and that the scope of protection of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
