Description

Technical Field

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

[0002] In order to improve the cooking experience, especially to solve the pain point of the hot and stuffy air environment in the kitchen during cooking in summer, people invented refrigeration range hoods. Refrigeration range hoods integrate air conditioning components into the range hoods. Condensation water will be generated during the refrigeration process, and the problem of condensation water treatment needs to be solved. The refrigeration range hoods currently on the market do not have the ability to treat condensation water alone. Condensation water is often discharged externally by drilling holes in the wall or introducing condensation water into the sewer pipe through pipes for external discharge. External water pipes are required, which increases installation costs. In addition, the discharge of condensation water causes long-term erosion of the user's external wall and dripping in the external environment. In addition, when the range hood works in cooling mode, the temperature of the condenser is relatively high. The prior art discloses a solution for cooling the condenser using condensed water, such as the Chinese utility model patent No. 202121615051.7 (authorization announcement No. CN215863614U), which discloses a liquid distributor and an air-conditioning range hood using the liquid distributor. The condenser and liquid distributor of the air-conditioning range hood are arranged in the smoke exhaust channel, and the evaporator is arranged in the air outlet channel. The condensed water condensed on the surface of the evaporator flows into the tube body of the liquid distributor and flows from the water outlet of the liquid distributor to the condenser. Although the air-conditioning range hood can effectively cool the condenser through condensed water, the unconsumed condensed water will still drip from the condenser when it flows through the surface of the condenser, thus affecting the reliability of the range hood. Moreover, since the condenser is in the oil fume channel, as the working time increases, oil stains will adhere to the condenser, thus affecting the adhesion of the condensed water to the condenser and reducing the water treatment capacity. In addition, the use of a liquid distributor is prone to uneven liquid distribution on the one hand, and on the other hand, it is not easy for the condensed water to fully contact the surface of the condenser, affecting its heat exchange effect.

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0019] like Figure 1 to Figure 2 As shown, the refrigeration range hood of this embodiment includes a range hood module 1, a compressor 2, a heat dissipation module 3 and an indoor module 4. The range hood module 1 includes a fan frame 11, a range hood fan 12 is installed inside the fan frame 11, an air inlet cavity is installed below the fan frame 11, and the air inlet cavity 13 has a smoke inlet, which is connected to the air inlet of the range hood fan 12. The heat dissipation module 3 includes a condenser 31 and a heat dissipation fan 32, and the indoor module 4 includes an evaporator 41 and an indoor fan 42. Figure 3 As shown, the compressor 2, the condenser 31 and the evaporator 41 are connected through a refrigerant pipeline, and the working principle is the same as that of the existing air conditioner, which will not be described in detail here.

[0020] The compressor 2, the heat dissipation module 3 and the indoor module 4 are all arranged outside the fan frame 11. Specifically, the heat dissipation module 3 and the indoor module 4 are all arranged above the fan frame 11. In this embodiment, the indoor module 4 is located on the left, the heat dissipation module is located on the right, and the compressor 2 is arranged on the left side of the fan frame 11 and below the indoor module 4. The range hood fan 12 is a centrifugal fan, and the fan outlet of the range hood fan 12 is arranged obliquely upward, so that sufficient installation space can be reserved above the range hood fan, and the fan outlet of the range hood fan 12 is located on the right side of the heat dissipation module 3.

[0021] The water pumping impeller 5 is installed above the fan frame 11 and is coaxially arranged with the heat dissipation fan 32. The water pumping impeller 5 and the heat dissipation fan 32 share a motor. Driven by the motor, the water pumping impeller 5 and the heat dissipation fan 32 rotate synchronously. A first water receiving box 61, a second water receiving box 62 and a third water receiving box 63 are also arranged outside the fan frame 11. Among them, the first water receiving box 61 is arranged below the evaporator 41. The first water receiving box 61 is used to receive condensed water condensed on the surface of the evaporator 41. The second water receiving box 62 is arranged above the first water receiving box 61. The condensed water in the first water receiving box 61 is transported to the second water receiving box 62 through the water pump 7 and the water outlet pipe 8. The water pumping impeller 5 is located above the second water receiving box 62. The water pumping impeller 5 continuously delivers the condensed water in the second water receiving box 62 to the condenser 31, so that the condensed water is fully in contact with the fins and copper tubes of the condenser 31 until the entire surface of the condenser 31 is filled. The finned condenser has a strong water storage capacity, which allows the condensed water to stay on the surface for a long time and fully exchange heat with the surface of the condenser 31. The third water receiving box 63 is arranged below the second water receiving box 62 and the condenser 31. The second water receiving box 62 has an overflow port 621. When the amount of water in the second water receiving box 62 is too much, it overflows from the overflow port 621 and flows into the third water receiving box 63. The condensed water that is not consumed by the condenser 31 also flows into the third water receiving box 63. The third water receiving box 63 is arranged above the first water receiving box 61. The condensed water in the third water receiving box 63 flows into the first water receiving box 61 through the return pipe 9 and is continuously pumped out by the water pump 7 to realize the recycling of the condensed water.

[0022] In addition, in this embodiment, a vent can be provided on the volute ring wall of the range fume extracting fan 12, and the air outlet of the heat dissipating fan 32 can be connected to the air inlet of the range fume extracting fan 12 through the vent. Along the air flow direction, the condenser 31 is arranged upstream of the heat dissipating fan 32, and the heat dissipating fan 32 forms a suction effect on the condenser 31. The heat dissipating fan 32 can absorb some atomized small water droplets and discharge them into the range fume extracting fan 12, and finally discharge them to the outside through the flue.
