Description

Technical Field

[0001] The utility model relates to a refrigeration device, in particular to a condenser of a refrigeration range hood and a refrigeration 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] For this purpose, a range hood with a refrigeration function has been disclosed in the prior art, which can blow out cold air from the housing of the range hood to cool down the kitchen. For example, a Chinese patent with application number 201810525673.7 discloses an air-conditioning range hood, in which the fume assembly of the air-conditioning range hood includes an oil fume channel; the air-conditioning assembly includes a condenser assembly, and the condenser assembly includes a condensation air inlet and a condensation air outlet, the condensation air outlet is connected to the oil fume channel, and the condensation air inlet is independent of the oil fume channel. However, the arrangement of this condenser uses the main fan for oil fume extraction to dissipate heat, which reduces the amount of oil fume sucked and exhausted, affecting the oil fume extraction effect.

[0004] There is also a kitchen air conditioner disclosed in a Chinese patent with application number 202110029969.1, which 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 range hood component includes an exhaust duct and a exhaust fan in the exhaust duct. The condenser is arranged around the outer wall of the exhaust duct.

[0005] This type of kitchen air conditioner can use oil smoke to dissipate heat from the condenser without the need for additional power. However, since the condenser is wrapped around the exhaust pipe, it is usually not possible to ensure that the condenser can be completely close to the exhaust pipe when wrapped, resulting in an air gap layer; and the oil smoke needs to pass through the heat-conducting smoke pipe to exchange heat with the pipe wall of the condenser, and the long heat exchange path will lead to low heat exchange efficiency. In addition, the condenser only dissipates heat through the oil smoke, and most of the oil smoke does not contact the condenser when passing through the condenser, and cannot drive the heat of the condenser, resulting in low heat exchange efficiency. The poor heat dissipation effect of the condenser will directly affect the cooling effect of the range hood air conditioner.

[0006] In addition, draining condensed water directly into the water collection box is not a good solution. Due to the influence of air humidity, the amount of condensed water produced varies, and there are requirements for the design of the water collection box capacity. Dumping the condensed water in the water collection box also brings inconvenience to users. Condensed water needs to be discharged into the sewer pipe. The drainage pipe is directly exposed outside the machine, which affects the appearance of the kitchen. Embedding it in the wall requires a hole in the wall.

[0007] Therefore, there is still room for further improvement. Utility Model Content

[0008] The first technical problem to be solved by the present invention is to provide a condenser for a refrigeration range hood in view of the deficiencies in the above-mentioned prior art, which can improve the heat exchange efficiency.

[0009] The second technical problem to be solved by the utility model is to provide a refrigeration range hood using the above condenser.

[0010] The technical solution adopted by the utility model to solve the first technical problem is: a condenser of a refrigeration range hood, characterized in that:

[0011] The condenser comprises a main body capable of conducting heat, and the main body is in the shape of a pipe;

[0012] At least two fluid passages are formed inside the wall portion of the main body, at least one of which is a refrigerant channel for refrigerant to pass through, and at least one of which is a cooling channel for coolant to pass through. The refrigerant channel is located on a side close to the space enclosed by the main body, and the cooling channel is located on a side away from the space enclosed by the main body.

[0013] By making the condenser as a whole in the shape of a pipe, the inside of the condenser can dissipate heat through the oil smoke passing through the inside of the pipe, while the outside can dissipate heat through the coolant, and the heat transfer path between the refrigerant channel and the dissipated oil smoke is short, so that the refrigerant flowing inside the condenser tube wall can be fully dissipated, thereby improving the overall heat exchange efficiency, and thus the refrigeration effect of the refrigeration component; and the single-sided air cooling and single-sided water cooling structure brings a better condenser heat exchange effect; in addition, compared with the solution with only a refrigerant channel, since the cooling channel is on the outside of the refrigerant channel, it can isolate the refrigerant heat from radiating to the outside of the condenser, thereby avoiding the heat from affecting the oil smoke suction component, especially when installed at the fan outlet, it can avoid affecting the electrical box installed in the same space.

[0014] Preferably, to ensure a shorter refrigerant and coolant heat transfer path, the wall of the main body includes at least three layers of heat conducting plates, the fluid passage is formed between adjacent two side heat conducting plates, and the refrigerant channel and the cooling channel are isolated from each other by one layer of the heat conducting plates.

[0015] Further, the refrigerant channel has a refrigerant inlet and a refrigerant outlet, and the cooling channel has a cold water inlet and a cold water outlet;

[0016] The main body is arranged vertically, and a first liquid collecting cavity and a second liquid collecting cavity are formed inside the wall of the main body. Each liquid collecting cavity extends vertically, and the refrigerant channel and the cooling channel penetrate the liquid collecting cavity at the corresponding position when passing through each liquid collecting cavity;

[0017] The first liquid collecting chamber is divided into a first refrigerant liquid collecting chamber on a side close to the space surrounded by the main body and a first cold water liquid collecting chamber on a side away from the space surrounded by the main body by one layer of heat conducting plates; the second liquid collecting chamber is divided into a second refrigerant liquid collecting chamber on a side close to the space surrounded by the main body and a second cold water liquid collecting chamber on a side away from the space surrounded by the main body;

[0018] The first refrigerant collecting chamber of the first collecting chamber is respectively connected to the refrigerant inlet and the refrigerant outlet for fluid communication, and a first partition arranged transversely is provided in the first refrigerant collecting chamber to separate the first refrigerant collecting chamber into two upper and lower parts; the second cold water collecting chamber of the second collecting chamber is respectively connected to the cold water inlet and the cold water outlet for fluid communication, and a second partition arranged transversely is provided in the second cold water collecting chamber to separate the second cold water collecting chamber into two upper and lower parts.

[0019] The design of the composite liquid collecting chamber ensures the reasonable arrangement of the refrigerant flow channel inlet and outlet connection ports and the circulating condensed water inlet and outlet connection ports. A liquid collecting chamber partition is provided in the liquid collecting chamber, so that the refrigerant or condensed water is layered up and down, extending the flow channel stroke and improving the heat exchange efficiency of the condenser.

[0020] The technical solution adopted by the utility model to solve the second technical problem is: a refrigeration range hood, including a range hood assembly and a refrigeration assembly, characterized in that: the refrigeration assembly includes the condenser as described above.

[0021] Furthermore, the condenser is arranged on the exhaust path of the refrigeration range hood. Along the flow path of the oil smoke, the condenser is arranged downstream of the oil smoke suction component. The heat dissipation of the condenser does not require an additional fan to dissipate heat. The centrifugal fan and the heat dissipation channel of the range hood are used to discharge heat to the outdoors or a public flue, thereby reducing the cost of the entire machine.

[0022] In order to facilitate installation and maintenance and reduce the space occupied by the range hood, the refrigeration component is arranged above the range hood component.

[0023] Preferably, the refrigeration assembly further comprises an evaporator capable of generating condensed water as the cooling liquid in the cooling channel.

[0024] Preferably, the condensed water is used effectively by pre-cooling the high-temperature condensate at the compressor outlet and circulating the refrigerant in the condenser. The refrigeration component also includes a water collection tank for receiving the condensed water generated by the evaporator, a water inlet pipe connecting the water collection tank with the cold water inlet fluid of the cooling channel, and a return pipe connecting the water collection tank with the cold water outlet fluid of the cooling channel, and a water pump is provided on the water inlet pipe.

[0025] Preferably, the water collecting tank includes a first water collecting tank and a second water collecting tank, the first water collecting tank is arranged below the evaporator, the second water collecting tank is arranged below the first water collecting tank, the first water collecting tank is fluidly connected to the second water collecting tank through a water conduit, and the water inlet pipe and the water return pipe are respectively fluidly connected to the second water collecting tank.

[0026] In order to prevent the high-temperature water from directly entering the water collecting tank after heat exchange, the refrigeration assembly also includes a spray device for spraying the return water pipe into the second water collecting tank.

[0027] Compared with the prior art, the advantages of the utility model are: by making the condenser as a whole in the shape of a pipe, the interior can dissipate heat through the oil smoke passing through the inside of the pipe, and the outside can dissipate heat through the coolant, and the heat transfer path between the refrigerant channel and the heat-dissipating oil smoke is short, so that the refrigerant flowing inside the condenser tube wall can be fully dissipated, thereby improving the overall heat exchange efficiency, and thus improving the refrigeration effect of the refrigeration component; and the structure of single-sided air cooling and single-sided water cooling brings better condenser heat exchange effect; the design of the composite liquid collecting chamber ensures the reasonable arrangement of the refrigerant flow channel inlet and outlet connection ports and the circulating condensed water inlet and outlet connection ports, and a liquid collecting chamber partition is provided in the liquid collecting chamber, so that the refrigerant or condensed water is layered up and down, extending the flow channel stroke, and the condenser heat exchange efficiency is higher; the condensed water generated by the refrigeration component is used to circulate and cool the refrigerant in the condenser, thereby realizing the effective utilization of condensed water.

[0038] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions.

[0039] In the description of the present utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate the orientation or position relationship based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Since the embodiments disclosed in the present utility model can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations. For example, "up" and "down" are not necessarily limited to directions opposite to or consistent with the direction of gravity. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of such features.

[0040] 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 fan 12 disposed in the first shell 11. In this embodiment, the range hood assembly is in the form of a commonly used side-suction range hood. Optionally, it can be any form of existing top suction, low suction, ceiling type, etc. The first shell 11 can be a combination of one or more shells.

[0041] The oil fume suction component and the refrigeration component constitute independent modules respectively. When installed, the refrigeration component is mounted on the oil fume suction component, so that the refrigeration component does not occupy the left and right sides of the first shell 11 of the oil fume suction component, which can avoid the fan frame (part of the first shell 11) used to set the fan 12 from being offset and affecting its own oil fume suction effect. Moreover, the two modules are installed independently, which can meet the needs of both new decoration users and old users who are changing their decoration.

[0042] The refrigeration assembly includes a second shell 21, a compressor 22, an evaporator 23, a condenser 24 and a cooling fan 25, wherein the second shell 21 is arranged on the first shell 11, 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.

[0043] A cold air outlet 211 is provided on the front side of the second housing 21, such as near the top. 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 a comfortable cooking environment temperature for the user. Air inlets 212 are provided on other sides of the second housing 21, such as the left and right sides, to replenish air (room temperature air) into the second housing 21.

[0044] The condenser 24 includes a main body 241 and a fluid passage. The main body 241 is in the shape of a hollow pipe, preferably a cylindrical shape, and the fluid passage is formed inside the wall of the main body 241. In the present embodiment, the main body 241 is arranged vertically, especially vertically, and the opposite ends (the upper and lower ends in the present embodiment) of the main body 241 are open. There are at least two fluid passages, at least one of which is a refrigerant passage 242 for refrigerant to pass through, and the refrigerant passage 242 has a refrigerant inlet 2421 and a refrigerant outlet 2422. At least one of the fluid passages is a cooling passage 243 for cooling liquid to pass through, which is independent of the refrigerant passage 242. The cooling passage 243 has a cold water inlet 2431 and a cold water outlet 2432. Liquid for cooling, such as condensed water, can be passed into the cooling passage 243, and external tap water can also be connected. In the present embodiment, condensed water is used, and the specific details will be described in detail below. The flow directions of the refrigerant in the refrigerant channel 242 and the cooling liquid in the cooling channel 243 can be opposite. For example, in the present embodiment, both channels are arranged in a spiral shape along the wall of the main body 241, the refrigerant inlet 2421 is located at the upper end, and the cold water inlet 2431 is located at the lower end, which will be described in detail below.

[0045] In this embodiment, the fluid passage includes a refrigerant passage 242 and a cooling passage 243. The wall of the main body 241 includes three layers of heat conducting plates 2411 arranged in sequence. The fluid passage is formed between two adjacent layers of heat conducting plates 2411. The two layers of heat conducting plates 2411 have a gap only at the position where the fluid passage is formed, and are fitted in other parts (the gap existing in the non-fluid passage due to process problems is regarded as a situation without gap). In this embodiment, the refrigerant passage 242 is located on the inner side of the cooling passage 243, that is, the refrigerant passage 242 is located on the side of the wall of the main body 241 close to the oil smoke (the side close to the space enclosed by the main body 241), and the cooling passage 243 is located on the side of the main body 241 away from the oil smoke (the side away from the space enclosed by the main body 241). The refrigerant passage 242 and the cooling passage 243 are separated by a layer of heat conducting plates 2411 located in the middle. Alternatively, the refrigerant channel 242 and the cooling channel 243 are both divided into two, three or even more branch channels after entering from the inlet, and the branch channels merge before the outlet.

[0046] Optionally, the heat conducting plate 2411 is a metal plate, such as an aluminum plate. Two aluminum plates are hot-rolled and formed, and the two aluminum plates are inflated to form the above-mentioned fluid passage, and then the whole is rolled into a desired shape. After hot rolling, the refrigerant in the fluid passage can withstand a pressure of up to 2.3MPa, and there is zero gap contact between the refrigerant and the heat conducting plate 2411, 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 commonly used in existing air conditioners or the winding type described in the background technology, 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.

[0047] See also Figure 6 , Figure 7-1 and Figure 7-2 The wall of the main body 241 also forms a first liquid collecting chamber 2441 and a second liquid collecting chamber 2442, each of which extends vertically and is arranged relative to the circumference, preferably symmetrically. The first liquid collecting chamber 2441 and the second liquid collecting chamber 2442 are both composite cavities, and the heat conducting plate 2411 in the middle layer also passes through the first liquid collecting chamber 2441 and the second liquid collecting chamber 2442 at the corresponding positions, so that the first liquid collecting chamber 2441 is divided into a first refrigerant liquid collecting chamber 2443 close to the inner side of the main body 241 (close to the side of the space surrounded by the main body 241) and a first cold water liquid collecting chamber 2444 close to the outer side of the main body 241 (away from the side of the space surrounded by the main body 241); the second liquid collecting chamber 2441 is divided into a second refrigerant liquid collecting chamber 2445 close to the inner side of the main body 241 and a second cold water liquid collecting chamber 2446 close to the outer side of the main body 241.

[0048] The first refrigerant collecting chamber 2443 of the first collecting chamber 2441 is connected to the refrigerant inlet 2421 and the refrigerant outlet 2422 respectively and is in fluid communication, and a first partition 251 arranged transversely is provided in the first refrigerant collecting chamber 2443 to separate the first refrigerant collecting chamber 2443 into two parts, an upper part and an lower part, and the first partition 251 is used to isolate refrigerants with different flow directions. The second cold water collecting chamber 2446 of the second collecting chamber 2442 is connected to the cold water inlet 2431 and the cold water outlet 2432 respectively and is in fluid communication, and a second partition 252 arranged transversely is provided in the second cold water collecting chamber 2446 to separate the second cold water collecting chamber 2446 into two parts, an upper part and an lower part, and the second partition 252 is used to isolate cold water with different flow rates.

[0049] Each refrigerant channel 242 and cooling channel 243 penetrates the corresponding liquid collecting cavity when passing through the liquid collecting cavity, so that each liquid collecting cavity separates each refrigerant channel 242 and cooling channel 243, forming a channel with a smaller length and each section is connected through the liquid collecting cavity. Figure 8 As shown by the arrow in , the flow path of the refrigerant is that after the refrigerant enters from the refrigerant inlet 2421, part of the refrigerant enters downward from the first refrigerant collecting chamber 2443. Part of the refrigerant in the first refrigerant collecting chamber 2443 goes directly downward until it encounters the first partition 251, and then turns to enter the refrigerant channel 242 at the corresponding position, while part of the refrigerant directly enters the refrigerant channel 242 at the corresponding position. The refrigerant entering the refrigerant channel 242 enters the second refrigerant collecting chamber 2445 and then flows downward, and enters the first refrigerant collecting chamber 2443 located below the first partition 251 in the opposite direction from the refrigerant channel 242 located below the first partition 251, and finally flows out from the refrigerant outlet 2422.

[0050] See also Fig. 9 As shown by the arrows in , the flow path of the cold water is that after the cold water enters from the cold water inlet 2431, part of the cold water goes directly upward from the second cold water collecting chamber 2446 until it meets the second partition 252, and then turns to enter the cold zone channel 243 at the corresponding position, while part of the cold water directly enters the cooling channel 243 at the corresponding position. The cold water entering the cooling channel 243 enters the first cold water collecting chamber 2444 and then flows upward, and enters the second cold water collecting chamber 2446 located above the second partition 252 from the cooling channel 243 located above the second partition 252 in the opposite direction, and finally flows out from the cold water outlet 2432.

[0051] On the oil fume flow path, the condenser 24 is arranged downstream of the fan 12, and it can be directly connected to the air outlet of the fan 12, or connected to the fan 12 through the air outlet cover 13, or connected to the smoke exhaust pipe 3 as a part of the smoke exhaust pipe. That is, the space surrounded by the heat conducting plate 2411 of the inner layer of the main body 241 constitutes the smoke exhaust channel 2412 through which the oil fume exhausted by the fan 12 passes before reaching the public flue or being discharged into the room, and the inner wall surface of the inner layer of the heat conducting plate 2411 (i.e. the inner wall surface of the main body 241) and the outer wall surface of the outer layer of the heat conducting plate 2411 (i.e. the outer wall surface of the main body 241) both constitute the heat dissipation surface. The inner heat dissipation surface dissipates heat through the oil fume passing through the smoke exhaust channel 2412, and the outer heat dissipation surface contacts the room temperature air entering the second shell 21 from the kitchen indoor environment during operation, and can also achieve a certain degree of heat dissipation. The room temperature air constitutes the heat dissipation fluid.

[0052] As described above, in this embodiment, the cooling channel 243 dissipates heat for the refrigerant through condensed water. To this end, the refrigeration assembly also includes a first water collecting tank 261, a second water collecting tank 262, a water pump 27, a water inlet pipe 271, a water return pipe 272 and a spray device 28. The first water collecting tank 261 is arranged below the evaporator 23 to collect the condensed water generated by the evaporator 23. The second water collecting tank 262 is arranged below the first water collecting tank 261. The condensed water in the first water collecting tank 261 is guided to the second water collecting tank 262 by gravity through the water guide pipe 263. The second water collecting tank 262 is connected to the cold water inlet 2431 through the water inlet pipe 271. The water inlet pipe 271 is provided with a water pump 27 to provide power for the condensed water to flow to the cooling channel 243. The water return pipe 272 is connected to the cold water outlet 2432 of the cooling channel 243 to lead out the water after heat exchange. The spray device 28 is disposed at the end of the return pipe 272 away from the cold water outlet 2432 and is located above the second water collecting tank 262. The spray device 28 evenly distributes the high-temperature water after heat exchange into the second water collecting tank 262, effectively cools the water after heat exchange, and prevents the high-temperature water from directly entering the second water collecting tank 262.

[0053] 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.
