Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a refrigeration type range hood. Background Art

[0002] Various refrigeration-type range hoods are disclosed in the prior art, which can realize all the functions of the range hood and the function of the air conditioner. The condenser is installed in the oil fume channel, and the condensed water is dripped on the condenser by a water pump and a liquid distributor, and the oil fume airflow is used to exchange heat with the condenser, so that the condensed water on the condenser evaporates. For example, the Chinese utility model patent "An air-conditioning range hood" with patent number 202220043436.9 (authorization announcement number CN 217004589 U) discloses such a refrigeration-type range hood, in which a compressor and an oil fume suction fan are provided in the casing of the range hood, and a smoke exhaust channel is formed downstream of the oil fume suction fan, and the air conditioner internal unit includes an evaporator, and the air conditioner internal unit has a return air port and an air outlet. A condenser is installed in the smoke exhaust channel, and the condensed water condensed on the surface of the evaporator can be transported to the surface of the condenser by a water pump. As the working time increases, oil and dirt will adhere to the condenser, which will affect the adhesion of condensed water to the condenser, thereby reducing the water treatment capacity.

[0003] In addition, during daily use of refrigeration range hoods, a large amount of grease will remain on the volute and impeller. After a long period of air drying and solidification, these grease will form a hard grease layer on the volute and impeller, which is very difficult to clean. Traditional range hoods on the market often do not have a cleaning function. Even if a cleaning function is added, it is simply to add a water pump and a heating rod to heat and spray the water added from the outside for cleaning. Additional parts are needed, which reduces the reliability of the whole machine, and the addition of water from the outside increases the complexity. In summary, there is a need for further improvement of existing refrigeration range hoods. Utility Model Content

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the refrigeration range hood of this embodiment includes a range hood fan 1, a compressor 2, a heat dissipation module 3 and an indoor module 4. The heat dissipation module 3 and the indoor module 4 are arranged outside the range hood fan 1. The heat dissipation module 3 includes a condenser 31 and a heat dissipation fan 32. The heat dissipation fan 32 is used to dissipate heat from the condenser 31. The indoor module 4 includes an evaporator 41 and an indoor fan 42. In the refrigeration mode, the indoor fan 42 blows out cold air. In this embodiment, along the air flow direction, the indoor fan 42 is arranged downstream of the evaporator 41, and the indoor fan 42 forms a suction effect on the evaporator 41. As shown in FIG. Figure 3 As shown, the compressor 2, the condenser 31 and the evaporator 41 are connected via the refrigerant pipeline 7. The compressor 2, the condenser 31 and the evaporator 41 constitute an air conditioning component, and its working principle can refer to the existing air conditioning principle and will not be described in detail here.

[0021] The range hood fan 1 and the heat dissipation fan 32 of this embodiment are both centrifugal fans, and the central axis of the impeller of the range hood fan 1 is parallel to the central axis of the impeller of the heat dissipation fan 32. The range hood fan 1 includes a volute 11, and a vent 12 is formed on the volute ring wall of the volute 11. The heat dissipation fan 32 is arranged above the range hood fan 1, and the air outlet of the heat dissipation fan 32 faces downward and toward the vent 12, that is, the air outlet of the heat dissipation fan 32 can be fluidly connected with the inside of the volute 11 through the vent 12. A valve 5 capable of opening and closing the vent is installed at the vent 12. When only the range hood is turned on, the vent 12 is closed to prevent oil smoke from contaminating the condenser 31. In the cooling mode, the vent 12 is opened, and the heat dissipation fan 32 blows the heat of the condenser 31 into the volute 11 of the range hood fan 1 and discharges it to the outside through the range hood fan 1. In this embodiment, the heat dissipation fan 32 is arranged downstream of the condenser 31, and the heat dissipation fan 32 forms a suction effect on the condenser 31.

[0022] A water receiving box 61 is installed below the condenser 31 and the evaporator 41. In this embodiment, the evaporator 41 is inclined relative to the vertical plane, and the condenser is vertically arranged. The projections of the evaporator 41 and the condenser 31 in the vertical direction fall within the water receiving box 61. The water receiving box 61 is used to receive the condensed water dripping from the surface of the evaporator 41 and the condensed water that is not consumed by the condenser 31.

[0023] The water inlet end of the water inlet pipe 62 is arranged on the water receiving box 61, the water pump 63 is installed on the water inlet pipe 62, the water outlet end of the water inlet pipe 62 is connected with the inlet end of the reversing valve 64, and the outlet end of the water inlet pipe 62 is connected with the first water outlet pipe 65 or the second water outlet pipe 66 through the switching of the reversing valve 64, the condensed water flowing out of the first water outlet pipe 65 is transported to the condenser 31, and the condensed water flowing out of the second water outlet pipe 66 is transported to the inside of the volute 11 through the vent 12. That is, the condensed water in the water receiving box 61 is divided into two outputs, one of which is transported to the condenser 31, and the other is transported to the inside of the volute 11 through the vent 12. In addition, in order to realize intelligent control, a water level sensor 67 is installed in the water receiving box 61, and a controller is also included, which can receive the output signal of the water level sensor 67 and control the reversing of the reversing valve 64 according to the received signal. In order to achieve a better condensate water spraying effect, a nozzle 68 with the water outlet direction facing the inside of the volute 11 is installed at the water outlet end of the second water outlet pipe 66 .

[0024] When working in the cooling mode, the condensed water condensed on the surface of the evaporator 41 can flow into the water receiving box 61, and the condensed water flows to the first water outlet pipe 65 through the reversing valve 64, and then pours onto the condenser 31, on the one hand, the cold capacity is recovered, and on the other hand, the condensed water is processed. When the condensed water processing effect is not good, the water receiving box 61 rises, and when the water level sensor 67 alarms, the reversing valve 64 is reversed, and the condensed water flows to the second water outlet pipe 66, and the range hood fan 1 is self-cleaned.
