Description

Technical Field

[0001] The present invention relates to the technical field of range hoods, and particularly to an air-conditioning range hood. Background Art

[0002] With the development of the technical field of range hoods, products integrating an air-conditioning system in range hoods have been gradually widely used. Integrating the air-conditioning system and the range hood together can save the overall installation space and simplify the installation process at the same time. The air-conditioning wind formed by the air-conditioning system can not only be used to adjust the indoor temperature, but also be sent into the flue of the range hood as an auxiliary way to deal with oil stains. For example, cold wind can also be used to cool the oil fume in the flue of the range hood, so that the oil fume condenses into oil beads and is discharged. However, when using the air-conditioning wind formed by the air-conditioning system in multiple aspects, the structural complexity of the entire air-conditioning range hood is significantly improved. Summary of the Invention

[0003] In view of the problem that the structural complexity of the above air-conditioning range hood is significantly improved, the present invention provides an air-conditioning range hood, which effectively controls the structural complexity of the air-conditioning range hood and reduces the implementation cost.

[0033] To make the above - mentioned objects, features, and advantages of the present invention more obvious and understandable, the following describes the detailed implementation manners of the present invention with reference to the accompanying drawings. Many specific details are set forth in the following description to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein. Those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0034] As Figures 1 to 4 shown, in one embodiment, an air - conditioner range hood 10 is provided, including:

[0035] An exhaust component 11;

[0036] A range - hood housing 12, the exhaust component 11 is installed in the range - hood housing 12, and a first installation cavity 121 and a second installation cavity 122 are provided on both sides of the exhaust component 11 in the range - hood housing 12;

[0037] An air - conditioning system 13, the air - conditioning system 13 includes a first heat exchanger 131 and a second heat exchanger 132 that are interconnected. The first heat exchanger 131 is located in the first installation cavity 121, and the second heat exchanger 132 is located in the second installation cavity 122;

[0038] An exhaust air component 14, the exhaust air component 14 is located above the exhaust component 11, and an exhaust passage communicating with the room is provided in the exhaust air component 14;

[0039] The shunt component 15 is installed in the range hood housing 12. A first drainage channel and a second drainage channel that are both communicated with the first installation cavity 121 are formed between the shunt component 15 and the range hood housing 12. The first drainage channel is communicated with the exhaust channel, and the second drainage channel is communicated with the air inlet of the air extraction component 11.

[0040] For an air-conditioning range hood 10 provided by the above solution, by reasonably arranging the positions of the air extraction component 11, the first heat exchanger 131, the second heat exchanger 132, and the exhaust component 14, the shunt component 15 installed in the range hood housing 12 can form the first drainage channel and the second drainage channel with a relatively simple structure, effectively controlling the complexity of the structure of the air-conditioning range hood 10. Specifically, the air extraction component 11 and the exhaust component 14 are located on the same side of the first heat exchanger 131, and it is relatively easy for the shunt component 15 to achieve the drainage process from the first installation cavity 121 to the air extraction component 11 and the exhaust component 14.

[0041] The first drainage channel can drain the air-conditioning air formed by the first heat exchanger 131 to the exhaust channel, and the second drainage channel can drain the air-conditioning air formed by the first heat exchanger 131 to the air extraction fan assembly. It can not only play a role in adjusting the indoor temperature, but also assist in dealing with oil fumes and reduce the pollution of the air extraction component 11 by oil stains.

[0042] Specifically, as Figure 3 and Figure 4 shown, in some embodiments, the air extraction component 11 includes a volute 111 and an impeller 112 arranged in the volute 111. The air inlet of the air extraction component 11 is the air inlet formed on the volute 111. When the impeller 112 in the volute 111 rotates, a negative pressure is formed in the volute 111, and oil fumes are sucked into the volute 111 from the air inlet under the action of the negative pressure. The air-conditioning air guided by the second drainage channel can also be sucked into the volute 111 under the action of the negative pressure.

[0043] Optionally, the air extraction component 11 can also be other devices capable of extracting oil fumes, which are not specifically limited here.

[0044] Furthermore, in one embodiment, the first heat exchanger 131 is an evaporator, and the second heat exchanger 132 is a condenser.

[0045] When the air conditioning system 13 operates, the evaporator absorbs external heat, causing cold air with a lower temperature to be formed in the first installation cavity 121. A part of the cold air enters the exhaust air channel from the first drainage channel, and then flows into the room along the exhaust air channel to lower the indoor temperature; another part of the cold air enters the air extraction assembly 11 along the second drainage channel to lower the temperature in the flue gas channel, causing the flue gas inhaled into the air extraction assembly 11 to be separated and condensed into oil beads.

[0046] Optionally, in another embodiment, the first heat exchanger 131 is a condenser, and the second heat exchanger 132 is an evaporator.

[0047] Further, as Figure 3 and Figure 4 shown, in one embodiment, the range hood housing 12 includes an outer housing 124, as well as a first partition 125 and a second partition 126 that are both disposed in the outer housing 124. The first partition 125 divides the space between the first heat exchanger 131 and the air extraction assembly 11. The part of the space enclosed by the outer housing 124 on the side of the first partition 125 facing the location of the first heat exchanger 131 is the first installation cavity 121. The second partition 126 divides the space between the air extraction assembly 11 and the second heat exchanger 132. The part of the space enclosed by the outer housing 124 on the side of the second partition 126 facing the location of the second heat exchanger 132 is the second installation cavity 122. The first partition 125 and the second partition 126 are arranged at intervals to form an intermediate installation cavity 123. The air extraction assembly 11 is installed in the intermediate installation cavity 123, and the air inlet of the air extraction assembly 11 is exposed in the intermediate installation cavity 123. The second drainage channel is communicated with the intermediate installation cavity 123.

[0048] The settings of the first partition 125 and the second partition 126 divide the space enclosed by the outer housing 124 into multiple spaces. Based on the fact that the air inlet of the air extraction assembly 11 is exposed in the intermediate installation cavity 123, when the air conditioning air is drained into the intermediate installation cavity 123 through the communication between the second drainage channel and the intermediate installation cavity 123, the air conditioning air will naturally be inhaled by the air extraction assembly 11.

[0049] Moreover, the settings of the first partition 125 and the second partition 126 can also prevent all the air conditioning air in the first installation cavity 121 and the second installation cavity 122 from being completely sucked away by the air extraction assembly 11, thereby ensuring that the air conditioning system 13 can normally implement the refrigeration or heating process.

[0050] Further, the first partition plate 125 separates the air extraction assembly 11 from the first heat exchanger 131, and the second partition plate 126 separates the air extraction assembly 11 from the second heat exchanger 132, which can also prevent the oil fume inhaled by the air extraction assembly 11 from contaminating the first heat exchanger 131 and the second heat exchanger 132. At the same time, it can also reduce the probability of the noise generated during the operation of the air conditioning system 13 being transmitted into the flue gas passage of the air conditioning range hood 10, avoiding noise superposition.

[0051] Specifically, in one embodiment, as Figure 2 shown, the peripheral housing 124 includes a front plate 1241. The air extraction assembly 11, the first heat exchanger 131, and the second heat exchanger 132 are all located on the side of the front plate 1241 facing the installation wall. An oil fume suction port 1242 communicating with the intermediate installation cavity 123 is provided on the front plate 1241. When the air extraction assembly 11 operates, indoor oil fume enters the intermediate installation cavity 123 from the oil fume suction port 1242.

[0052] After the air conditioning range hood 10 is installed, generally the peripheral housing 124 leans against the installation wall, the cooking stove is located below the air conditioning range hood 10, and the installation wall is the wall that the air conditioning range hood 10 is attached to during installation.

[0053] Further, in one embodiment, the second partition plate 126 is in sealing contact with the front plate 1241, which can prevent the air conditioning air in the second installation cavity 122 from entering the intermediate installation cavity 123, and at the same time prevent the oil fume in the intermediate installation cavity 123 from entering the second installation cavity 122, and can further avoid the occurrence of noise superposition.

[0054] Further, in one embodiment, as Figure 2 shown, a ventilation gap 16 is formed at an interval between the front plate 1241 and the first partition plate 125. The air conditioning air in the first installation cavity 121 can enter the intermediate installation cavity 123 through the ventilation gap 16.

[0055] Specifically, as Figure 2 、 Figure 3 、 Figure 4 and Figure 6As shown, in one embodiment, the diverter assembly 15 includes a diverter box 151. A portion of the diverter box 151 is located in the intermediate mounting cavity 123, and another portion of the diverter box 151 is disposed between the first heat exchanger 131 and the front plate 1241 through the ventilation gap 16. The diverter box 151 does not completely block the ventilation gap 16. In other words, at least a portion of the ventilation gap 16 is unblocked, and the unblocked portion of the ventilation gap 16 communicates with the first mounting cavity 121 and the second mounting cavity 122.

[0056] The diverter box 151 is provided with a drainage inlet in the portion facing the first heat exchanger 131, and the portion of the diverter box 151 located within the intermediate mounting cavity 123 is provided with a drainage outlet connected to the exhaust passage. Both the drainage inlet and the drainage outlet are connected to the interior of the diverter box 151 to form the first drainage passage.

[0057] like Figure 4 As shown by the dotted arrow, part of the air conditioning air in the first installation cavity 121 flows into the middle installation cavity 123 from the position of the ventilation gap 16 that is not blocked by the diverter box 151; Figure 4 As shown by the solid arrow, another portion of the air-conditioning air in the first installation cavity 121 flows from the diverter box 151 into the exhaust channel.

[0058] like Figure 2 As shown, the front plate 1241 can guide the air-conditioning wind in the first installation cavity 121, so that the air-conditioning wind in the first installation cavity 121 is located on the inner side of the front plate 1241. Under the suction action of the exhaust component 11, part of the air-conditioning wind in the first installation cavity 121 passes through the ventilation gap 16 into the middle installation cavity 123 and is sucked into the exhaust component 11.

[0059] Furthermore, the smoke sucked in from the oil smoke suction port 1242 is first mixed with the cold air flowing into the middle installation cavity 123 from the ventilation gap 16, and the oil stains in the smoke condense into oil droplets and then gather in the oil cup.

[0060] Specifically, the position in the ventilation gap 16 that is not blocked by the diverter box 151 can be any position, as long as at least a portion of the ventilation gap 16 can serve as a channel connecting the first installation cavity 121 and the middle installation cavity 123.

[0061] For example, in one embodiment, Figure 3 、 Figure 4 and Figure 6As shown, the part of the flow dividing box 151 located between the first heat exchanger 131 and the front plate 1241 is the introduction part 1514. The introduction part 1514 faces a part of the first heat exchanger 131, and the part of the first heat exchanger 131 facing the introduction part 1514 is the upper heat exchange part, and the part of the first heat exchanger 131 not facing the introduction part 1514 is the lower heat exchange part. The upper heat exchange part is located on the side of the lower heat exchange part close to the exhaust air assembly 14.

[0062] It can be understood that at the angles shown in Figure 3 , Figure 4 and Figure 6 , the upper part of the first heat exchanger 131 is blocked by the introduction part 1514, and the lower part of the first heat exchanger 131 is exposed outside the flow dividing box 151. Therefore, at least a section of the ventilation gap 16 located below the flow dividing box 151 is not blocked, and the air-conditioning air in the first installation cavity 121 can flow into the intermediate installation cavity 123 from this unblocked part.

[0063] Based on the fact that the exhaust air assembly 14 is located above the air extraction assembly 11, the flow dividing box 151 mainly introduces the air-conditioning air into the exhaust air assembly 14 by covering the upper part of the first heat exchanger 131. The drainage path is short, the structure of the flow dividing assembly 15 is relatively simple, the installation is more convenient, and the manufacturing cost is also lower.

[0064] Furthermore, in one embodiment, as shown in Figure 3 , Figure 4 and Figure 6 , the part of the flow dividing box 151 located in the intermediate installation cavity 123 is the extraction part 1515. The top surface of the extraction part 1515 is docked with the exhaust air assembly 14. The drainage outlet is formed on the top surface of the extraction part 1515, and the inlet of the exhaust air channel is formed at the position on the exhaust air assembly 14 facing the drainage outlet. The air-conditioning air drained in the flow dividing box 151 finally conducts upward into the exhaust air channel.

[0065] As shown in Figure 3 , Figure 4 and Figure 6 , the flow dividing box 151 forms an L-shaped trend. The extraction part 1515 is arranged horizontally, and the introduction part 1514 extends downward relative to the extraction part 1515.

[0066] More specifically, in one embodiment, as shown in Figure 2 and Figure 6As shown, the diverter box 151 is a flat box body, wherein the two surfaces with larger areas are the top and bottom surfaces of the box body respectively. The diverter box 151 includes a box cover 1511, a box bottom 1512 and a side panel 1513. The box cover 1511 and the box bottom 1512 are arranged relatively spaced apart. The box bottom 1512 is located on the side of the box cover 1511 away from the front plate 1241 of the outer shell 124. The side panel 1513 is connected between the box cover 1511 and the box bottom 1512. Figure 2 As shown, the air inlet is formed on the box bottom plate 1512, and the portion of the box bottom plate 1512 located on the side of the first partition plate 125 close to the first heat exchanger 131 is divided to form the air inlet, leaving only the portion of the box bottom plate 1512 located on the side of the first partition plate 125 close to the exhaust assembly 11. Alternatively, it can be understood that the box bottom plate 1512 is located on the side of the first partition plate 125 close to the exhaust assembly 11, and the portion of the box cover plate 1511 located on the side of the first partition plate 125 close to the first heat exchanger 131 is directly opposite to the first heat exchanger 131, without the box bottom plate 1512 blocking the middle.

[0067] The edge of the box bottom plate 1512 used to form the drainage inlet is sealed against the first partition plate to ensure that the air-conditioning wind entering the diversion box 151 from the drainage inlet will not leak into the middle installation cavity 123. The box cover plate 1511 and the first partition plate 125 are arranged at intervals. The air-conditioning wind in the first installation cavity 121 diffuses in the direction close to the box cover plate 1511. After being partially blocked by the box cover plate 1511, part of the air-conditioning wind flows to the left along the box cover plate 1511. During the circulation process, this part of the air-conditioning wind passes through the interval gap between the box cover plate 1511 and the first partition plate 125 and enters the lead-out portion 1515, and finally flows to the exhaust component 14.

[0068] Furthermore, in one embodiment, Figures 1 to 5 As shown, the outer shell 124 further includes two side plates 1243 arranged opposite to each other, wherein one side plate 1243 is located on a side of the first heat exchanger 131 away from the air extraction assembly 11, and the other side plate 1243 is located on a side of the second heat exchanger 132 away from the air extraction assembly 11. The left and right sides of the front plate 1241 are respectively in abutment and sealed against the two side plates 1243.

[0069] The box cover 1511 of the diverter box 151 is in abutment and sealed against the side plate 1243 close to the first heat exchanger 131 .

[0070] The space between this side plate 1243 close to the first heat exchanger 131 and the first partition 125 is the first installation cavity 121, and the space between this side plate 1243 close to the second heat exchanger 132 and the second partition 126 is the second installation cavity 122.

[0071] Further, in one embodiment, as Figure 2 shown, the peripheral housing 124 further includes a back plate 1244, and the air extraction assembly 11, the first heat exchanger 131, and the second heat exchanger 132 are all located on the side of the back plate 1244 away from the installation wall surface. As Figure 5 shown, the peripheral housing 124 further includes a top plate 1245, and the air extraction assembly 11, the first heat exchanger 131, and the second heat exchanger 132 are all located below the top plate 1245.

[0072] The back plate 1244, the front plate 1241, the top plate 1245, the first partition 125, and one side plate 1243 enclose the first installation cavity 121, the back plate 1244, the front plate 1241, the top plate 1245, the second partition 126, and the other side plate 1243 enclose the second installation cavity 122, and the back plate 1244, the front plate 1241, the top plate 1245, the first partition 125, and the second partition 126 enclose the intermediate installation cavity 123.

[0073] Further, as Figures 1 to 5 shown, in one embodiment, a first ventilation opening 127 is provided at a position on the top plate 1245 opposite to the first heat exchanger 131. The air outside the air-conditioning range hood 10 enters the first installation cavity 121 from the first ventilation opening 127.

[0074] A second ventilation opening 128 is provided at a position on the top plate 1245 opposite to the second heat exchanger 132. The air outside the air-conditioning range hood 10 enters the second installation cavity 122 from the second ventilation opening 128.

[0075] Further, in one embodiment, as Figure 6 shown, the air-conditioning range hood 10 further includes a first filter element 17, and the first filter element 17 is located between the first ventilation opening 127 and the first heat exchanger 131. This prevents dust from falling onto the first heat exchanger 131 when the outside air enters the first installation cavity 121.

[0076] Similarly, the air-conditioning range hood 10 further includes a second filter element 18, and the second filter element 18 is located between the second ventilation opening 128 and the second heat exchanger 132.

[0077] Further, as Figure 5As shown, in one embodiment, the air conditioning system 13 further includes a compressor 133. The compressor 133 is connected between the first heat exchanger 131 and the second heat exchanger 132. The compressor 133 is located in the second installation cavity 122, behind the second heat exchanger 132, and below the second filter element 18.

[0078] On the one hand, the space in the second installation cavity 122 is fully utilized, making the structure of the air - conditioning range hood 10 more compact. On the other hand, since the compressor 133 is located below the second filter element 18, dust deposition on the compressor 133 can be avoided.

[0079] Further, as Figures 2 to 6 shown, in one embodiment, the air conditioning system 13 further includes a throttling element 134 and a refrigerant pipeline 135. The refrigerant pipeline 135 spans across the middle installation cavity 123.
