[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] For this reason, the prior art has disclosed a range hood with a refrigeration function, which can blow cold air from the housing of the range hood to cool down the kitchen. Special kitchen air conditioners, one is a split design, which requires the installation of an outdoor unit, but most kitchens do not have an equipment platform, making installation inconvenient. The other is an integrated design, such as an air-conditioning hood disclosed in a Chinese patent with application number 201810525673.7, in which the fume assembly of the air-conditioning hood includes an fume channel; the air-conditioning assembly includes a condenser assembly, the condenser assembly includes a condensation air inlet and a condensation air outlet, the condensation air outlet is connected to the fume channel, and the condensation air inlet is independent of the fume channel. However, in this way, the air-conditioning assembly and the fume assembly are integrated into one, resulting in a large size and increased weight of the whole machine, and the repair and daily maintenance of the fume assembly part become troublesome and difficult. Moreover, because the condenser uses an independent heat dissipation fan, it is large in size and cannot be installed in rooms with low floor heights. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a refrigeration range hood in view of the deficiencies in the above-mentioned prior art, wherein the range hood assembly and the refrigeration assembly are reasonably arranged, the installation position is flexible, and the range hood is applicable to various installation scenarios.

[0005] The technical solution adopted by the utility model to solve the above technical problems is: a refrigeration range hood, including a range hood assembly, a refrigeration assembly and a smoke exhaust pipe, wherein the refrigeration assembly includes an evaporator and a condenser, and is characterized in that:

[0006] The refrigeration assembly is used to be arranged on the ceiling. The condenser includes a heat-conducting main body. The main body is in a pipe shape and has an exhaust passage for oil smoke to pass through formed inside. The exhaust pipe is divided into two sections and is respectively connected to both ends of the main body.

[0007] The fume extraction component and the refrigeration component are scientifically integrated by coordinating the refrigeration component with the exhaust duct of the fume extraction component. The condenser becomes a part of the exhaust duct, and the fume flowing through the exhaust duct is used to dissipate heat, so that no holes are required in the exterior wall. The product can be applied to existing range hoods on the market, and the installation position is flexible and suitable for various installation scenarios. It also saves a dedicated heat dissipation fan for the condenser, and the product is smaller in size, lighter in weight, easier to use and install, and has a lower cost.

[0008] In order to receive the condensed water of the evaporator, a first water receiving pan for receiving the condensed water generated by the evaporator is provided below the evaporator, and a drain pipe is connected to the first water receiving pan.

[0010] In order to facilitate the adjustment of the humidity of the blown cold air and reduce the drainage of condensed water, the refrigeration component also includes a cold air outlet for blowing out the cold air after heat exchange around the evaporator, and an atomizing device capable of atomizing the condensed water in the first water receiving tray is arranged between the evaporator and the cold air outlet.

[0011] In order to further improve the heat dissipation efficiency of the condenser, make full use of the condensed water and reduce the drainage of the condensed water, the refrigeration assembly also includes a spray device arranged above the condenser, and the spray device and the first water receiving tray are connected by a water pipe, and a water pump is arranged on the water pipe.

[0012] In order to facilitate the use of condensed water generated by the condenser, a second water receiving tray is provided below the condenser, and the first water receiving tray can also receive the condensed water in the second water receiving tray.

[0013] In order to facilitate the linkage between the oil fume suction component and the refrigeration component, the oil fume suction component further includes a first wireless communication module, and the refrigeration component further includes a second wireless communication module capable of communicating with the first wireless communication module.

[0014] Preferably, the condenser further comprises a refrigerant channel, and the refrigerant channel is formed inside the wall of the main body. By making the condenser as a whole in the shape of a pipe, the inside thereof can dissipate heat through the oil smoke passing through the inside of the pipe, and the outside thereof can dissipate heat through the air in the external environment, and the heat transfer path between the refrigerant channel and the oil smoke or air dissipating heat is short, thereby enabling the refrigerant flowing inside the condenser tube wall to be sufficiently dissipated, thereby improving the overall heat exchange efficiency, and further improving the refrigeration effect of the refrigeration component.

[0015] Preferably, in order to ensure a shorter refrigerant heat transfer path, the wall portion of the main body includes two layers of heat conducting plates, and the refrigerant channel is formed between the two layers of heat conducting plates.

[0016] According to one aspect of the utility model, the refrigerant channel is spirally wound along the wall of the main body.

[0017] According to another aspect of the utility model, the refrigerant channel is in a parallel reflux shape along the wall of the main body, and the refrigerant channel includes at least three vertically extending first channels, a second channel connected between the upper ends of two adjacent first channels, and a third channel connected between the lower ends of two adjacent first channels, and the second channel and the third channel extend in opposite directions at both ends of the same first channel.

[0018] Furthermore, the main body is cylindrical or rectangular, and a heat dissipation pipe is arranged inside the space surrounded by the main body of the condenser, and the heat dissipation pipe is a hollow pipe with two ends open. Since the wind speed in the center of the main body is fast, the heat dissipation efficiency can be improved by arranging the heat dissipation pipe.

[0019] Furthermore, a heat conducting sheet is connected between the outer wall of the heat dissipation pipe and the inner wall of the main body, thereby facilitating rapid heat conduction between the main body and the heat dissipation pipe.

[0020] In order to achieve a better heat exchange effect, the adverse effect of the number of heat conducting plates on the smoke exhaust resistance must be taken into account. The number of the heat conducting plates is n, and n≤15 is satisfied.

In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0038] Embodiment 1

[0039] See also Figure 1 to Figure 6 A refrigeration range hood includes a range hood assembly and a refrigeration assembly, wherein the range hood assembly includes a first shell 11 and a main fan 12 disposed in the first shell 11. In this embodiment, the range hood assembly is in the form of a commonly used top-suction range hood. Optionally, it can be any existing side-suction, low-suction, ceiling-mounted, etc. The first shell 11 can be a combination of one or more shells.

[0040] The range hood further comprises a smoke exhaust duct 3 for exhausting the smoke sucked by the main fan 12 to a common flue.

[0041] The fume suction assembly and the refrigeration assembly constitute independent modules respectively, and the refrigeration assembly is arranged on the smoke exhaust duct 3, which is located above the kitchen ceiling 100. The refrigeration assembly includes a second shell 21, a compressor 22, an evaporator 23, a condenser 24 and a cooling fan 25, wherein the compressor 22, the evaporator 23, the condenser 24 and the cooling fan 25 can be arranged in the second shell 21, and a refrigerant passage is formed between the compressor 22, the evaporator 23 and the condenser 24. The working principle of the refrigeration assembly is the same as the prior art. The specific structure of the evaporator 23 and the condenser 24 and their related components will be described in detail below.

[0042] A cold air outlet 211 is provided at the bottom of the second shell 21, and the evaporator 23 can be arranged near the cold air outlet 211. The cold air after heat exchange in the evaporator 23 is blown out from the cold air outlet 211 into the kitchen through the cooling fan 25 to provide users with a comfortable cooking environment temperature. Figure 2The arrow at the middle cold air outlet 211 indicates the blowing direction. The other sides of the second shell 21, such as the left and right sides, are provided with air inlets 212 to replenish air (room temperature air) into the second shell 21. When the cooling fan 25 is in operation, the room temperature air outside the second shell 21 can be sucked into the second shell 21, and after heat exchange with the evaporator 23, it is blown out from the cold air outlet 211 into the kitchen. In order to prevent impurities and the like from being sucked into the refrigeration component, a filter 213 can be set at the air inlet 212 so that the clean cold air after filtering is blown into the second shell 21, so as to prevent particulate matter in the air from adhering to the evaporator 23, thereby affecting the refrigeration efficiency. A first temperature sensor 214 and a humidity sensor 215 are provided at the cold air outlet 211 for detecting the temperature and humidity of the blown cold air. A second temperature sensor 216 can also be provided at the air inlet 212 for detecting the temperature of the inhaled air.

[0043] A UV sterilization lamp and a negative ion generating device (not shown) may also be provided at the cold air outlet 211 to disinfect and sterilize the cold air again. The negative ion generator releases a certain concentration of negative ions to further improve the cleanliness and healthiness of the cold air.

[0044] A first water receiving pan 261 is provided below the evaporator 23 to receive the condensed water generated by the evaporator 23. A water level sensor 263 is provided in the first water receiving pan 261 to monitor the water level in the first water receiving pan 261. The first water receiving pan 261 is connected to the oil cup 13 of the range hood assembly through a drain pipe 28. A drain valve 281 is provided on the drain pipe 28 to control whether the first water receiving pan 261 drains water. When the water level sensor 263 detects that the water level in the first water receiving pan 261 reaches the set limit water level, the drain valve 281 opens to drain water, and the water flows into the oil cup 13 through the drain pipe 28. Alternatively, the drain pipe 28 can also be connected to the kitchen drain pipe, so that the condensed water in the first water receiving pan 261 is directly discharged into the drain pipe.

[0045] In order to improve the cooling effect and provide a better user experience, an atomizing device 27 is provided between the evaporator 23 and the cold air outlet 211, which can atomize the condensed water in the first water receiving tray 261, thereby changing the humidity of the cold air blown out. The operation of the atomizing device 27 can be controlled according to the air humidity detected by the humidity sensor 215.

[0046] The oil fume suction component further includes a first wireless communication module 14, and the refrigeration component further includes a second wireless communication module 29, whereby through the cooperation of the first wireless communication module 14 and the second wireless communication module 29, the refrigeration component communicates with the oil fume suction component to achieve linkage.

[0047] The indoor unit and outdoor unit of the refrigeration assembly are integrated, and the smoke exhaust pipe 3 of the range hood is used for heat dissipation, so that no hole is required in the outer wall. Specifically, the condenser 24 includes a main body 241 and a refrigerant channel 242. The main body 241 is in the shape of a hollow pipe, preferably a cylindrical shape, and the refrigerant channel 242 is formed inside the wall of the main body 241. In the present embodiment, the main body 241 is arranged horizontally, especially horizontally, and the refrigerant channel 242 is spirally wound along the wall of the main body 241. The two ends of the main body 241 are respectively connected to the smoke exhaust pipe 3 (the smoke exhaust pipe 3 is divided into two sections in the present embodiment, respectively placed at the two ends of the main body 241, which is equivalent to the condenser 24 constituting a part of the smoke exhaust pipe 3), so that the main body 241 can be used for the exhaust of oil smoke.

[0048] The wall of the main body 241 includes two layers of heat conducting plates 2411, and the refrigerant channel 242 is formed between the two layers of heat conducting plates 2411. The two layers of heat conducting plates 2411 have a gap only at the position where the refrigerant channel 242 is formed, and the other parts are all fitted (the gaps in the parts outside the refrigerant channel 242 caused by processing problems, such as bubbles, should be regarded as a situation without gaps). Optionally, the heat conducting plate 2411 is a metal plate, such as an aluminum plate. Two pieces of aluminum plates are hot-rolled and pressed, and the space between the two pieces of aluminum plates is inflated to form the above-mentioned refrigerant channel 242, and then the whole is rolled into the desired shape. After hot rolling, the refrigerant in the refrigerant channel 242 can withstand a pressure of up to 2.3MPa, and there is zero gap contact between the refrigerant and the heat conducting material, and the heat exchange efficiency is extremely high, so the surface temperature of the condenser is not higher than 50°C under natural conditions. However, in the fin-type or winding-type air conditioners commonly used in existing air conditioners, the refrigerant and the heat-conducting material cannot be completely matched without gaps, so the heat transfer is not smooth, resulting in a high temperature of the condenser itself, which in turn affects the overall cooling effect of the refrigeration component.

[0049] Thus, the space enclosed by the heat conducting plate 2411 of the inner layer of the main body 241 constitutes a smoke exhaust passage 2412 through which the oil smoke exhausted by the main fan 12 passes before reaching the common flue, and the inner wall surface of the inner heat conducting plate 2411 (i.e., the inner wall surface 2413 of the main body 241) and the outer wall surface of the outer heat conducting plate 2411 (i.e., the outer wall surface 2414 of the main body 241) both constitute heat dissipation surfaces. The inner heat dissipation surface dissipates heat through the oil smoke passing through the smoke exhaust passage 2412, and the outer heat dissipation surface contacts the room temperature air entering the second shell 21 from the indoor environment of the kitchen during operation, and can also achieve a certain degree of heat dissipation. The room temperature air constitutes a heat dissipation fluid.

[0050] By means of the above-mentioned arrangement of the condenser 24 , heat dissipation can be achieved by utilizing the oil smoke passing through the condenser 24 .

[0051] The refrigerant channel 242 has a refrigerant inlet 2421 and a refrigerant outlet 2422 . After the refrigerant enters from 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 from the refrigerant outlet 2422 , thereby flowing out from the refrigerant outlet 2422 .

[0052] The control method of the range hood comprises the following steps:

[0053] 1) The range hood is turned on, and the second temperature sensor 216 detects the ambient temperature T0, and determines whether T0 ≥ T is established, where T is the preset temperature at which the air conditioner needs to be turned on for refrigeration. If not, the refrigeration component is not started. If yes, proceed to step 2);

[0054] 2) The refrigeration component is turned on, and the water level sensor 263 detects the water level in the first water receiving tray 261 to determine whether the water level reaches the limit value. If not, it works normally. If yes, it goes to step 3);

[0055] 3) The drain valve 281 is opened to drain water, the water level in the first water receiving tray 261 drops to a safe water level, and then the drain valve 281 is closed.

[0056] Embodiment 2

[0057] See also Figure 7 In this embodiment, the difference from the above-mentioned embodiment 1 is that the main body 241 is wound into a spiral column as a whole.

[0058] Embodiment 3

[0059] See also Figure 8 and Fig. 9 In this embodiment, the difference from the above-mentioned embodiment 1 is that the refrigerant channel 242 is in a horizontal parallel reflux shape. The refrigerant channel 242 includes at least three first channels 2423 extending laterally, 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. The second channel 2424 and the third channel 2425 are staggered, 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, while the third channel 2425 extends in the direction of the other adjacent first channel 2423 of the first channel 2423. The second channel 2424 is in an upwardly protruding curved shape, preferably an arc shape, and the third channel 2425 is in a downwardly protruding curved shape, preferably also an arc shape, where "upward" and "downward" are corresponding. Figure 8In the actual installation state, since the main body 241 is arranged horizontally, the second channel 2424 usually protrudes to the left and the third channel 2425 protrudes to the right.

[0060] After entering the refrigerant inlet 2421, the refrigerant may 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 as to flow out of the refrigerant outlet 2422. The refrigerant inlet 2421 and the refrigerant outlet 2422 may be located at the same end of the main body 241 in the axial direction ( Fig.10 , radial inflow and outflow), located at opposite ends of the axial direction of the main body 241 ( Fig.11 ), or although located at the same end of the main body 241 in the axial direction, it realizes axial inflow and outflow, see Fig.12 . The above Figure 10 to Figure 12 The arrows in the figure show the flow path of the refrigerant.

[0061] In order to further improve the heat exchange efficiency, a heat dissipation pipe 243 may be provided inside the space enclosed by the main body 241 of the condenser 24. Preferably, the heat dissipation pipe 243 may be a hollow cylinder with openings at both ends of the axial direction, and may be provided at the center of the main body 241, preferably coaxial with the main body 241. A heat conducting sheet 244 is connected between the outer wall of the heat dissipation body 243 and the inner wall surface 2413 of the main body 241. The heat conducting sheet 244 may have at least two and be radially distributed. The heat dissipation pipe 243 and the heat conducting sheet 244 are both made of heat conducting materials and can conduct heat, such as made of metal, more preferably made of aluminum. Thus, the heat released by the refrigerant channel 242 can be conducted radially inward and outward through the heat conducting sheets 244 evenly arranged in the circumferential direction, and the wind speed at the center of the heat dissipation pipe 243 is large and the heat dissipation is faster.

[0062] To achieve better heat exchange effect, the adverse effect of the number of heat conducting sheets 244 on smoke exhaust resistance must be taken into account. Preferably, the number of heat conducting sheets 244 is n≤15. To ensure the heat transfer efficiency of the central heat dissipation pipe 243, the diameter of the heat dissipation pipe 243 is d, the diameter of the main body 241 is D, and 0.2≤d / D≤0.5 is satisfied.

[0063] The form of the refrigerant channel 242 in this embodiment can also be used in the second embodiment. The heat dissipation pipe 243 and the heat conducting sheet 244 can also be used in the first embodiment.

[0064] In addition, alternatively, the main body 241 may also be a hollow rectangular parallelepiped.

[0065] Embodiment 4

[0066] See also Fig.11In this embodiment, the difference from the above-mentioned embodiment 1 is that a second water receiving tray 262 is provided below the condenser 24 , and the two water receiving trays are fluidically connected, so that the condensed water in the second water receiving tray 262 can flow into the first water receiving tray 261 .

[0067] The refrigeration component also includes a spray device 30, which is connected to the first water receiving tray 261 through a water pipe 301. A water pump 302 is provided on the water pipe 301 to pump water in the first water receiving tray 261 to the spray device 30, so that the spray device 30 sprays cold water onto the outer surface of the condenser 24 to force heat dissipation, thereby improving the refrigeration effect and air-conditioning efficiency.

[0068] The condenser 24 in this embodiment may also adopt the structure described in the second or third embodiment.

[0069] The "fluid communication" referred to in the present invention refers to the spatial position relationship between two parts or parts (hereinafter collectively referred to as the first part and the second part), that is, the fluid (gas, liquid or a mixture of the two) can flow from the first part along the flow path or / and be transported to the second part. The first part and the second part can be directly connected, or the first part and the second part can be indirectly connected through at least one third party. The third party can be a fluid channel such as a pipe, channel, duct, guide member, hole, groove, etc., or it can be a chamber allowing fluid to flow through, or a combination of the above.
