Description

Technical Field

[0001] The invention relates to the field of kitchen appliances, and in particular to an integrated air-conditioning type range hood. Background Art

[0002] With the improvement of material living standards, people have higher and higher requirements for kitchen environment. People need to use stoves and other appliances during cooking, which will generate a lot of heat in the kitchen, causing the temperature of the entire space to rise, making the environmental comfort decrease. Most families use temporary fans to solve this problem. However, this method is not only inconvenient, but also occupies kitchen area. To address this problem, the prior art adds a refrigeration module to the range hood to deliver cold air to the kitchen and improve the environmental comfort.

[0003] At present, most of the range hoods with cooling function adopt the solution of semiconductor chip cooling, such as patent number CN105222193 B, CN 105987464 A, etc. However, the cooling efficiency of semiconductor chips is low, the cooling power is small, and it is difficult to achieve a good cooling effect. Therefore, some solutions adopt compressor cooling, such as patent number CN 111288545 A, CN205402845 U, etc. However, these solutions make the overall volume of the range hood too large, occupying more kitchen space, making the overall decoration of the kitchen inconsistent; and most of the range hoods with cooling function have their air inlets set on the left and right sides of the range hood, such as patent number CN111288525 A, etc. This will make the installation requirements of the range hood higher, and the kitchen decoration must reserve enough space on the left and right sides of the range hood to ensure smooth air intake on the left and right sides of the range hood, and it is impossible to achieve cabinet integration. Summary of the invention

[0004] The object of the present invention is to provide an integrated air-conditioning range hood to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The technical solutions adopted to solve the above technical problems are:

[0006] An integrated air-conditioning range hood comprises a range hood body and a refrigeration assembly, wherein the range hood body is provided with a smoke collecting chamber, a cold air channel, and a hot air channel, wherein the cold air channel has a first cold air inlet and a first cold air outlet, and the hot air channel has a first hot air inlet and a first hot air outlet, wherein the first cold air inlet and the first hot air inlet are arranged on the top surface of the range hood body, the first hot air outlet is communicated with the smoke collecting chamber, and the first cold air outlet is communicated with the outside of the range hood body; the refrigeration assembly comprises an air-conditioning casing, a compressor, a first heat exchanger, and a second heat exchanger, wherein the air-conditioning casing has an inner portion thereof. A hot air cavity, a cold air cavity and an air inlet cavity are provided, and the air inlet cavity is communicated with the hot air cavity and the cold air cavity at the same time. The air inlet cavity is provided with an air inlet connected with the outside of the air-conditioning casing, and the air-conditioning casing is fixed to the top surface of the range hood body, the hot air cavity is provided with a second hot air outlet connected with the first hot air inlet, and the cold air cavity is provided with a second cold air outlet connected with the first cold air inlet, the first heat exchanger is installed in the hot air cavity, and the second heat exchanger is installed in the cold air cavity, and the compressor, the first heat exchanger and the second heat exchanger are connected through a refrigerant pipeline.

[0007] The beneficial effects of the present invention are as follows: when in use, under the operation of the compressor, the air entering from the air inlet and passing through the cold air cavity exchanges heat with the second heat exchanger, and the cooled cold air passes through the second cold air outlet, the first hot air inlet, and the cold air channel in sequence and is discharged from the first cold air outlet, thereby achieving the purpose of air conditioning cooling; the air entering from the air inlet and passing through the hot air cavity exchanges heat with the second heat exchanger, and the heated hot air passes through the second hot air outlet, the first hot air inlet, and the hot air channel in sequence and enters the smoke collecting chamber, The hot air is discharged to the outside together with the smoke in the smoke collecting chamber, so as to achieve the purpose of heat dissipation. Compared with the prior art, the refrigeration component adopts compressor refrigeration, which greatly improves the refrigeration efficiency. At the same time, since the air-conditioning casing is fixed to the top surface of the range hood body, the hot air cavity and the cold air cavity in the air-conditioning casing share an air inlet (that is, the hot air and the cold air share the air inlet together), and the hot air discharged by the refrigeration component enters the smoke collecting chamber through the hot air channel, heat dissipation is also achieved while the range hood is exhausting smoke, thereby greatly improving the integration of the range hood and reducing the size of the range hood.

[0008] As a further improvement of the above technical solution, an installation cavity is further provided in the air-conditioning casing, the air intake cavity is connected to the hot air cavity through the installation cavity, and the compressor is installed in the installation cavity.

[0009] Since the compressor will generate a certain amount of heat during operation, once the heat dissipation is not good and overheating occurs, the performance of the compressor will be greatly affected. The compressor is set in the installation cavity. The air intake cavity in this scheme is connected to the hot air cavity through the installation cavity, so that the air before entering the hot air cavity can first pass through the installation cavity, so that the air can cool the outside of the compressor, thereby avoiding the compressor from overheating during operation; at the same time, the compressor can also be installed in a hidden manner, making the appearance of the range hood more tidy, avoiding the compressor from being exposed and causing oil accumulation on the outside, resulting in a short circuit.

[0010] It should be noted that the temperature of the air after heat exchange with the compressor is much lower than the temperature of the first heat exchanger when it is working, and the air entering the hot air cavity further exchanges heat with the first heat exchanger.

[0011] As a further improvement of the above technical solution, the air inlet is arranged on the front side of the upper part of the air conditioner casing, and an air inlet screen is arranged at the inlet of the air inlet.

[0012] This can extend the distance between the air inlet and the first cold air outlet and the oil fume, preventing turbulence or inhalation of dirty oil fume gas; the air inlet screen can filter the air entering from the air inlet to prevent foreign matter from entering the refrigeration component and causing blockage of the channel.

[0013] As a further improvement of the above technical solution, the refrigeration component further includes a decorative enclosure, which is arranged around the periphery of the refrigeration component and has a gap reserved for air intake into the air inlet.

[0014] The decorative enclosure can wrap the periphery of the refrigeration component, so that the refrigeration component and the range hood body are integrated, which improves the appearance and also has the effect of blocking oil smoke.

[0015] As a further improvement of the above technical solution, an air filter is installed at the air inlet, which can completely filter the air entering the refrigeration component, filter out the oil smoke in the air, and improve the heat exchange effect of the first heat exchanger and the second heat exchanger.

[0016] As a further improvement of the above technical solution, a cold air fan is installed on the cold air channel, and a heat dissipation fan is installed on the hot air channel.

[0017] Under the action of the cooling fan and the heat dissipation fan, the power of blowing out cold air and the power of discharging hot air can be increased, thereby improving the cooling efficiency of the refrigeration component. At the same time, the overall integration of the range hood can be further improved, and the overall size of the range hood can be reduced.

[0018] As a further improvement of the above technical solution, there are multiple first cold air outlets, and the multiple first cold air outlets are arranged at left and right intervals on the front side of the range hood body.

[0019] The cooled cold air is blown out from the first cold air outlet. Multiple first cold air outlets can be set according to different needs. At the same time, the first cold air outlet is arranged on the front side of the range hood main body, and can blow air toward the front, so that people can directly feel the coolness during cooking. It is also convenient for users to carry out cabinet integrated design when installing the range hood. Only the first cold air outlet in the front needs to be exposed, and the range hood can be close to the cabinet wall on the left and right, making the kitchen more beautiful.

[0020] As a further improvement of the above technical solution, the first cold air outlet is provided with rotatable air guide grille blades, and the number of the air guide grille blades is at least one.

[0021] When in use, the blowing direction can be adjusted according to different needs of people. Specifically, the angle of the air guide grid blades is adjusted so that the cold air can be blown out from the first cold air outlet in the set direction.

[0022] As a further improvement of the above technical solution, the range hood main body also includes an air outlet shell, which is installed in the range hood main body, a part or all of the cold air channel is arranged in the air outlet shell, the first cold air outlet is arranged on the air outlet shell, and a condensed water discharge outlet is arranged at the bottom of the air outlet shell.

[0023] During the cooling process of the refrigeration component, condensed water will be generated in the cold air cavity, so the condensed water can flow along the cold air channel into the air outlet shell and be discharged from the condensed water outlet to avoid dripping at the first cold air outlet.

[0024] There may be various forms of cold air channels and hot air channels. In some other schemes, the cold air channels may be tubular, formed by stamping sheet metal, or may be integrally formed with the range hood body. There may also be various installation methods. The cold air channels and hot air channels may be arranged on the outer surface of the range hood body or inside the range hood body. The cold air channels and hot air channels in this scheme are both arranged inside the range hood body, which allows the cold air fan and the heat dissipation fan to be hidden and installed inside the range hood body, making the outside of the range hood body tidier.

[0025] As a further improvement of the above technical solution, the range hood main body also includes a fume fan, the smoke collecting chamber is provided with a smoke inlet and a smoke exhaust port, the fume fan is arranged in the smoke collecting chamber between the smoke inlet and the smoke exhaust port, and the first hot air outlet is arranged on the negative pressure side of the fume fan.

[0026] The oil fume fan is mainly used to absorb oil fume. At the same time, the negative pressure generated in the process of absorbing oil fume can discharge the extracted hot air to the outside through the flue. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] Reference Figures 1 to 7 The present invention provides an integrated air-conditioning range hood as follows:

[0040] The integrated air-conditioning type range hood in this embodiment includes a range hood body 100 and a refrigeration assembly 200 .

[0041] A smoke collecting chamber 110, a cold air channel, and a hot air channel are arranged inside the range hood body 100. The cold air channel has a first cold air inlet 120 and a first cold air outlet 130, and the hot air channel has a first hot air inlet 140 and a first hot air outlet 150. Figure 4 As shown, the first cold air inlet 120 and the first hot air inlet 140 are arranged on the top surface of the range hood body 100, the first hot air outlet 150 is connected to the smoke collecting chamber 110, the first cold air outlet 130 is connected to the outside of the range hood body 100, the first cold air outlet 130 is arranged on the front side of the range hood body 100, and two first cold air outlets 130 are arranged at intervals on the left and right in this embodiment. The smoke collecting chamber 110 is provided with a smoking port 111 and a smoke exhaust port 112, and a fume fan 600 is arranged in the smoke collecting chamber 110 between the smoking port 111 and the smoke exhaust port 112, and the first hot air outlet 150 is arranged on the negative pressure side of the fume fan 600.

[0042] like Figure 5 As shown, the refrigeration assembly 200 includes an air conditioning casing 210, a compressor 220, a first heat exchanger 230, and a second heat exchanger 240. A hot air cavity 211, a cold air cavity 212, and an air intake cavity 213 are arranged inside the air conditioning casing 210. The air intake cavity 213 is communicated with the hot air cavity 211 and the cold air cavity 212 at the same time. The air intake cavity 213 is provided with an air inlet 217 that is communicated with the outside of the air conditioning casing 210. The air inlet 217 is provided with a The air inlet screen 218 is arranged at the front side of the upper part of the air conditioner housing 210, and the entrance of the air inlet 217 is provided, which can extend the distance between the air inlet 217 and the first cold air outlet 130 and the oil smoke, and prevent turbulence or inhalation of dirty oil smoke gas; the air inlet screen 218 can filter the air entering from the air inlet 217 to a certain extent, and prevent foreign matter from entering the refrigeration component 200 and causing blockage of the passage; the air conditioner housing 210 is fixed to the top surface of the range hood body 100, such as Figure 6As shown, the hot air cavity 211 is provided with a second hot air outlet 214 connected to the first hot air inlet 140, and the cold air cavity 212 is provided with a second cold air outlet 215 connected to the first cold air inlet 120. Figure 5 As shown, the first heat exchanger 230 is installed in the hot air cavity 211 , and the second heat exchanger 240 is installed in the cold air cavity 212 .

[0043] The compressor 220, the first heat exchanger 230 and the second heat exchanger 240 in this embodiment are connected by a refrigerant pipeline, wherein the first heat exchanger 230 transfers heat to the air passing through the hot air cavity 211, and the second heat exchanger 240 cools the air passing through the cold air cavity 212. This is the prior art of air conditioning and will not be described in detail here.

[0044] At the same time, if Figure 1 and Figure 2 As shown, a cold air fan 300 is installed on the cold air channel, and a heat dissipation fan 400 is installed on the hot air channel.

[0045] During use, with the operation of the cold air fan 300, the heat dissipation fan 400, the fume fan 600 and the compressor 220, the air entering from the air inlet 217 and passing through the cold air cavity 212 exchanges heat with the second heat exchanger 240, and the cooled cold air passes through the second cold air outlet 215, the first hot air inlet 140, and the cold air channel in turn and is discharged from the first cold air outlet 130, thereby achieving the purpose of air conditioning cooling; the air entering from the air inlet 217 and passing through the hot air cavity 211 exchanges heat with the first heat exchanger 230, and the heated hot air passes through the second hot air outlet 214, the first hot air inlet 140 and the hot air channel in turn and enters the smoke collecting cavity 110, and the hot air is discharged outdoors together with the smoke in the smoke collecting cavity 110, thereby achieving the purpose of heat dissipation.

[0046] The refrigeration component 200 of this embodiment adopts a compressor 220 for refrigeration, which can improve the refrigeration efficiency. At the same time, since the air-conditioning casing 210 is fixed to the top surface of the range hood body 100, the hot air cavity 211 and the cold air cavity 212 in the air-conditioning casing 210 share an air inlet, that is, the hot air and the cold air share the air inlet 217, and the hot air exhausted by the refrigeration component 200 enters the smoke collecting chamber 110 through the hot air channel, heat dissipation is also achieved while the range hood is exhausting smoke, thereby greatly improving the integration of the range hood and reducing the size of the range hood.

[0047] Furthermore, in order to avoid the phenomenon of overheating of the compressor 220 during operation and the phenomenon of oil accumulation outside due to the exposure of the compressor 220, which leads to a short circuit, an installation cavity 216 is further provided in the air-conditioning casing 210, and the air intake cavity 213 is connected to the hot air cavity 211 through the installation cavity 216. The compressor 220 is installed in the installation cavity 216. The compressor 220 will generate a certain amount of heat during operation. Once overheating occurs due to poor heat dissipation, the performance of the compressor 220 will be greatly affected. The compressor 220 is set in the installation cavity 216, and the air intake cavity 213 is connected to the hot air cavity 211 through the installation cavity 216. The air before entering the hot air cavity 211 can first pass through the installation cavity 216, so that the air can cool the outside of the compressor 220, thereby avoiding the phenomenon of overheating of the compressor 220 during operation, and also improving the aesthetics of the range hood. Since the temperature of the air after heat exchange with the compressor 220 is much lower than the temperature of the first heat exchanger 230 when it is working, the air entering the hot air cavity 211 can further exchange heat with the first heat exchanger 230 .

[0048] In addition, an air filter (not shown) is installed at the air inlet 217. The air filter can completely filter the air entering the refrigeration assembly 200, filter out the oil smoke in the air, and improve the heat exchange effect of the first heat exchanger 230 and the second heat exchanger 240.

[0049] In order to further improve the aesthetics of the appearance, the refrigeration component 200 also includes a decorative panel 250, which is arranged around the periphery of the refrigeration component 200. The decorative panel 250 has a gap reserved for the air intake port 217. The decorative panel 250 can wrap the periphery of the refrigeration component 200, so that the refrigeration component 200 is integrated with the range hood body 100, which improves the appearance and also has the effect of blocking oil smoke.

[0050] Furthermore, if Figure 1 and Figure 3 The first cold air outlet 130 is provided with a rotatable air guide blade 131, and the number of the air guide blade 131 is set to at least one. When in use, the blowing direction can be adjusted according to different needs of people. Specifically, by turning the angle of the air guide blade 131, the cold air can be blown out from the first cold air outlet 130 in a set direction. Figure 7As shown, the range hood body 100 also includes an air outlet shell 500, which is installed in the range hood body 100, and a part or all of the cold air channel is arranged in the air outlet shell 500. The first cold air outlet 130 is arranged on the air outlet shell 500, and a condensate discharge port 510 is arranged at the bottom of the air outlet shell 500. During the refrigeration process of the refrigeration component 200, since condensate water is generated in the cold air cavity 212, the condensate water at this time can flow along the cold air channel into the air outlet shell 500 and be led out from the condensate discharge port 510 to avoid dripping at the first cold air outlet 130.

[0051] In some embodiments, there may be various forms of cold air channels and hot air channels. In some other schemes, the cold air channels may be tubular, formed by sheet metal through stamping, or may be integrally formed with the range hood body 100. There may also be various installation methods. The cold air channels and hot air channels may be arranged on the outer surface of the range hood body 100, or may be arranged inside the range hood body 100. The cold air channels and hot air channels in this embodiment are both arranged inside the range hood body 100, which allows the cold air fan 300 and the heat dissipation fan 400 to be hidden and installed inside the range hood body 100, making the exterior of the range hood body 100 tidier.

[0052] In some embodiments, there can be multiple installation positions for the cold air fan 300 and the heat dissipation fan 400. The cold air fan 300 can be installed in the cold air cavity 212 and connected to the second cold air outlet 215; the heat dissipation fan 400 can be installed in the hot air cavity 211 and connected to the second hot air outlet 214; or the cold air fan 300 and the heat dissipation fan 400 are integrated into one fan, which is installed in the air inlet cavity 213.

[0053] There are also various installation positions for the range hood fan 600 . The range hood fan 600 may be installed on the outside of the range hood body 100 , or on the smoke exhaust port 112 .

[0054] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
