Description

Technical Field

[0001] The utility model relates to a heat exchange technology, in particular to a condenser of a refrigerating range hood and a refrigerating range hood using the condenser. Background Art

[0002] With the improvement of material living standards, people have higher and higher requirements for kitchen environment. People need to use stoves during cooking, which will generate a lot of heat in the kitchen, causing the temperature of the entire space to rise and the comfort of the environment to decrease. At present, most families use temporary fans to solve this problem. However, this method is not only inconvenient, but also occupies kitchen area.

[0003] To this end, a range hood with a refrigeration function has been disclosed in the prior art, which can blow cold air from the housing of the range hood to cool down the kitchen. For example, a kitchen air conditioner and a control method thereof are disclosed in the Chinese invention patent with application number 202110029969.1, wherein the kitchen air conditioner includes an air conditioning component and a range hood component, the air conditioning component includes a compressor, a condenser, a throttling element, and an evaporator, the compressor, the condenser, the throttling element, and the evaporator are connected to form a refrigerant refrigeration cycle, the range hood component includes a smoke exhaust duct and a smoke exhaust fan in the smoke exhaust duct, and the condenser is arranged around the outer peripheral wall of the smoke exhaust duct.

[0004] The above-mentioned condenser surrounds the outer peripheral wall of the smoke exhaust duct. In order to ensure the refrigeration efficiency, the height of the condenser needs to meet certain requirements and should not be made too low, thereby affecting the height occupied by the range hood in the cabinet. Utility Model Content

[0005] The first technical problem to be solved by the utility model is to provide a condenser for a refrigeration range hood in view of the deficiencies in the above-mentioned prior art, which can reduce the height of the condenser while ensuring the refrigeration efficiency, thereby reducing the height occupied by the range hood in the cabinet.

[0006] The second technical problem to be solved by the utility model is to provide a refrigeration range hood using the above condenser.

[0007] The technical solution adopted by the utility model to solve the above-mentioned first technical problem is: a condenser of a refrigeration range hood, characterized in that: the condenser includes a main body capable of conducting heat and a refrigerant channel arranged on the main body, the main body includes a first main body in the shape of a hollow pipe and a second main body in the shape of a double helical column, in the cross section of the main body, the second main body includes an integrated first part, a second part and a third part, the third part is located in the middle of the first main body, the third part includes a first end and a second end, the first part is spirally wound from the first end along a first direction to the inner wall surface of the first body, the second part is spirally wound from the second end along a second direction to the inner wall surface of the first body, the first direction and the second direction are opposite, the first part and the second part are spaced apart; in the first body, the spacing part between the first part and the second part constitutes a smoke exhaust channel.

[0008] The condenser is designed with a double helix structure, which can lengthen the flow of the refrigerant channel. Compared with the condenser with a single helix structure in the prior art, the height of the condenser of this embodiment can be made lower, which can reduce the height occupied by the range hood in the cabinet.

[0009] In order to avoid the double helix structure being too densely designed and causing the condenser to be blocked during long-term use, the minimum interval between the first part and the second part is Δ, Δ≥15mm.

[0011] Preferably, the refrigerant channel is spirally wound along the wall of the main body.

[0012] Preferably, the refrigerant channels are in a parallel reflux shape, and the main body and the refrigerant channels are arranged vertically.

[0013] Preferably, the refrigerant channel includes at least three longitudinally extending first channels, a second channel connected between one end of each of two adjacent first channels, and a third channel connected between the other ends of two adjacent first channels, and the second channel and the third channel are staggered.

[0014] The technical solution adopted by the utility model to solve the above-mentioned second technical problem is: a refrigeration range hood, including a fume suction component and a refrigeration component, the refrigeration component includes the condenser as described above, and the condenser is arranged downstream of the fume suction component on the fume flow path.

[0015] In order to dissipate heat through oil smoke, the oil smoke suction assembly includes a first shell and a main fan arranged in the first shell, the main fan includes a main fan output end, and the condenser is arranged at the main fan output end.

[0018] Compared with the prior art, the advantage of the present invention is that the condenser is designed with a double helix structure, which can lengthen the flow of the refrigerant channel. Therefore, compared with the condenser with a single helix structure in the prior art, the height of the condenser of this embodiment can be made lower, which can reduce the height occupied by the range hood in the cabinet.

[0029] Embodiment 1

[0030] See also Figure 1 A refrigeration range hood includes a range hood assembly and a refrigeration assembly. The range hood assembly includes a first shell 11 and a main fan 12 disposed in the first shell 11. The main fan 12 includes a main fan output terminal 121. A fume hood 13 is disposed under the first shell 11. In this embodiment, the range hood assembly shown is in the form of a commonly used top-suction range hood. Optionally, it can be any form of existing side-suction, low-suction, ceiling-mounted, etc. The first shell 11 can be a combination of one or more shells.

[0031] The refrigeration assembly includes a second shell 21, a compressor 22, an evaporator 23 and a condenser. The second shell 21 is arranged on the smoke hood 13. The compressor 22, the evaporator 23 and the condenser can all be arranged in the second shell 21, and a refrigerant passage is formed between the compressor 22, the evaporator 23 and the condenser, and the flow direction and working principle of the refrigerant are the same as those of the prior art.

[0032] The refrigeration assembly also includes a cooling fan 25, which can absorb and discharge the cold air after heat exchange in the evaporator 23. A water receiving pan 26 for receiving condensed water from the evaporator 23 is provided below the evaporator 23.

[0033] See also Figure 1 to Figure 3 The condenser includes a main body 241 and a refrigerant passage 242. The refrigerant passage 242 is formed inside a wall portion of the main body 241.

[0034] The main body 241 is a first body 2415 in the shape of a hollow pipe and a second body in the shape of a double helical column formed in the first body 2415. In the cross section of the main body 241, the second body includes an integrated first portion 2411, a second portion 2412 and a third portion 2413. The third portion 2413 is located in the middle of the first body 2415. The third portion 2413 includes a first end 24131 and a second end 24132. The first portion 2411 is spirally wound from the first end 24131 to the inner wall surface of the first body 2415 along a first direction x, and the second portion 2412 is spirally wound from the second end 24132 to the inner wall surface of the first body 2415 along a second direction y. The first direction x and the second direction y are opposite. Here, the first direction x and the second direction y are the directions in which the corresponding portion just starts to spirally wind from the third portion 2413, as shown in FIG. Figure 3 As shown, in this embodiment, the first direction x is clockwise, and the second direction y is counterclockwise, so as to avoid interference between the first part 2411 and the second part 2412, and facilitate the winding of the main body 241. After the spiral is wound for a certain distance, the first part 2411 and the second part 2412 are wound along the same direction, showing a state where the first part 2411 and the second part 2412 are spaced apart and close to parallel. Therefore, in the first body 2415, the interval between the first part 2411 and the second part constitutes the smoke exhaust channel 2414. In order to avoid the double helix structure design being too dense, causing the condenser to be blocked due to long-term use, the minimum interval between the first part 2411 and the second part 2412 is Δ, preferably, Δ≥15mm. The refrigerant channel 242 is spirally wound on the wall of the main body 241.

[0035] On the oil fume flow path, the condenser is arranged downstream of the oil fume suction assembly. The condenser is arranged at the main fan output end 121. The condenser is designed with a double helix structure, which can make the flow of the refrigerant channel 242 longer. Therefore, compared with the condenser with a single helix structure in the prior art, the height of the condenser of this embodiment can be made lower, which can reduce the height occupied by the range hood in the cabinet.

[0036] Embodiment 2

[0037] See also Figure 4 to Figure 7, the refrigerant channel 242 is parallel to the wall of the main body 241 and is refluxed, and the main body 241 and the refrigerant channel 242 are arranged vertically. The refrigerant channel 242 includes at least three first channels 2423 extending longitudinally, a second channel 2424 connected between one end of each of two adjacent first channels 2423, and a third channel 2425 connected between the other ends of two adjacent first channels 2423, and the second channel 2424 and the third channel 2425 are arranged in a staggered manner. That is, the second channel 2424 and the third channel 2425 extend in opposite directions at both ends of the same first channel 2423, the second channel 2424 extends in the direction of one of the adjacent first channels 2423 of the first channel 2423, and the third channel 2425 extends in the direction of another adjacent first channel 2423 of the first channel 2423. The second channel 2424 is in a curved shape that bulges upward, preferably in an arc shape, and the third channel 2425 is in a curved shape that bulges downward, preferably also in an arc shape.

[0038] The refrigerant channel 242 has a refrigerant inlet 2421 and a refrigerant outlet 2422. Figure 4 to Figure 7 After the refrigerant enters the refrigerant inlet 2421, it can be divided into one, two, three, or even more paths, and then merged into one path before flowing out of the refrigerant outlet 2422, so that it flows out of the refrigerant outlet 2422. The refrigerant inlet 2421 and the refrigerant outlet 2422 can be located at the same end of the main body 241 axially ( Figure 5 , radial inflow and outflow), located at opposite ends of the axial direction of the main body 241 ( Figure 6 ), or although located at the same end of the main body 241 in the axial direction, it realizes axial inflow and outflow, see Figure 7 . The above Figure 5 to Figure 7 The arrows in the figure show the flow path of the refrigerant.

[0039] The condenser of the utility model has the advantages of small wind resistance, high heat transfer efficiency, and no blockage. While meeting the heat dissipation requirements of the air conditioner, it has little effect on the smoke extraction effect of the smoke extraction component. The shape and structure of the condenser are not limited to cylindrical shapes, but can also be other shapes such as rectangles. The double helix structure is not limited to Archimedean spirals, logarithmic spirals, etc., and will not significantly increase wind resistance while ensuring that the heat exchange area meets the heat exchange requirements. If the internal size space allows, heat dissipation fins or refrigerant channels can also be added to the exhaust channel 2414 of the condenser to further enhance the heat transfer effect.
