Description

Technical Field

[0001] The utility model relates to the technical field of range hoods, in particular to an air-conditioning type range hood. Background Art

[0002] In order to improve the user's cooking experience, people have invented various air-conditioning hoods to provide cold air to the kitchen in summer and warm air in winter. The air-conditioning hood integrates the air-conditioning component with the range hood, and an air-conditioning outlet is opened on the shell of the range hood. The air-conditioning hood can work in multiple different modes. As long as the air-conditioning mode is turned on, the air-conditioning outlet will blow out cold air or hot air, which can be blown directly to the cook or to the kitchen, thereby effectively improving the cook's cooking experience. For the air-conditioning hood working in the cooling mode, in order to improve the energy efficiency of the air conditioner, people have designed a structure in which the condenser is installed in the exhaust channel. The exhaust channel also constitutes a heat dissipation channel, that is, the heat of the condenser is taken away by the oil smoke, and the condenser is dissipated to improve its heat exchange effect. Since the condenser temperature is high, if it is only dissipated by the oil smoke airflow, the heat dissipation effect is not good. For this reason, people have invented a structure that uses air-conditioning condensed water to dissipate heat from the condenser, that is, the air-conditioning condensed water is transported to the surface of the condenser, and the condensed water is used to reduce the surface temperature of the condenser, thereby improving its heat exchange effect.

[0003] For example, the Chinese utility model patent with patent number CN202320196584.9 (publication number CN219550622U) discloses a refrigeration-type range hood, which includes an upper box and a lower cavity. An air conditioner module is provided outside the upper box. The upper box is divided into a smoke exhaust cavity and a heat dissipation cavity. A smoke exhaust fan is installed in the smoke exhaust cavity. The heat dissipation cavity is connected to the smoke exhaust cavity through a heat dissipation outlet. A condenser is installed in the heat dissipation cavity. The condensed water condensed on the evaporator can drip onto or be transported to the condenser. A heat dissipation fan and a water pump are installed below the condenser. The heat dissipation fan and the water pump are coaxially arranged and rotated under the drive of the same motor. The condensed water that has not been consumed by the condenser is pumped back to the condenser through the water pump or discharged to the outside of the upper box. The condensed water that has not been consumed by the condenser in the refrigeration range hood can be pumped back to the condenser through the water pump, and continue to rely on the high temperature of the condenser surface for heat exchange and evaporation consumption, or it can be discharged to the outside of the upper box through the water pump.

[0004] Most of the current condensed water is used to cool the condenser as shown in the above patent, and the unevaporated condensed water is discharged externally. However, the discharged condensed water is not fully utilized and is prone to cause environmental problems, such as erosion of the wall.

[0005] In addition, the range hood fan usually becomes dirty after use and also needs to be cleaned. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an air-conditioning type range hood in view of the current status of the prior art, in which condensed water can not only cool the condenser but also clean the range hood fan.

[0007] The technical solution adopted by the utility model to solve the above technical problems is: an air-conditioning type range hood, comprising a machine body and an air-conditioning module arranged on the machine body, the air-conditioning module comprising a compressor, a condenser and an evaporator, the compressor, the condenser and the evaporator are connected through a refrigerant pipeline, and the condensed water condensed by the evaporator is transported to the condenser; the machine body has a smoke exhaust cavity inside, and a range hood fan is installed in the smoke exhaust cavity;

[0009] If the water pump delivers water to the range hood fan and the condenser at the same time, the power of the water pump needs to be relatively large. In order to reduce the cost, the water pump is provided with a block that can selectively block the first water outlet or the second water outlet, and the water pump is provided with a driving mechanism that can drive the block to slide. In this way, the water pump can selectively deliver water to the range hood fan or the condenser, and the driving mechanism can adopt existing driving parts such as motors or electromagnets.

[0010] In order to enable the block to selectively block the first water outlet or the second water outlet, the first water outlet and the second water outlet are arranged on the same side wall of the water pump, and the block is slidably arranged on the inner wall surface of the side wall.

[0011] In order to transport the condensed water condensed in the evaporator to the condenser, a water delivery pipe for transporting the condensed water of the evaporator to the condenser is provided between the evaporator and the condenser.

[0012] Preferably, the condenser is located below the evaporator so that water flows onto the condenser under the action of gravity.

[0013] In order to collect the condensed water which is not evaporated by the condenser in the water collecting box, the water collecting box is located below the condenser.

[0014] In order to ensure the performance of the air conditioning components, the condenser needs to be cooled. The body also has a cooling cavity, the condenser is arranged in the cooling cavity, and a cooling fan is arranged in the cooling cavity. The body is provided with a cooling air inlet and a cooling air outlet connected to the cooling cavity. The air inlet of the cooling fan is connected to the cooling air inlet, and the air outlet of the cooling fan is connected to the cooling air outlet.

[0015] Preferably, the range fumes exhaust fan comprises a volute and an impeller arranged in the volute, and the volute is provided with an air inlet connected to the air outlet of the heat dissipation fan, and the air inlet is the heat dissipation outlet. In this way, the hot air blown out from the heat dissipation fan blows toward the impeller, slowing down the oil accumulation rate of the impeller.

[0016] In order to increase the area of ​​the hot air blown out from the heat dissipation fan flowing through the impeller, an air guide plate is provided at the air inlet, and the air guide plate extends along the circumference of the impeller. The air guide plate guides the hot air blown out from the heat dissipation fan, so that the hot air flows along the impeller.

[0017] Preferably, the air-conditioning range hood further comprises a controller, the condenser is provided with a temperature sensor, the temperature sensor is electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the heat dissipation fan. When it is detected that the temperature of the condenser is not high enough, the speed of the heat dissipation fan is reduced to maintain the temperature of the blown air, thereby improving the effect of slowing down the oil accumulation of the impeller.

[0018] Compared with the prior art, the advantages of the utility model are as follows: the utility model provides a water collecting box to collect condensed water that has not been evaporated by the condenser, and a water pump is provided in the water collecting box, so that the condensed water collected in the water collecting box can be sucked to the range hood fan or the condenser to clean the range hood fan or to dissipate heat from the condenser.

[0026] The condensed water condensed by the evaporator 4 is transported to the condenser 3, and the condensed water is used to dissipate heat from the condenser 3. In this embodiment, a water delivery pipe 41 for delivering the condensed water of the compressor 2 to the condenser 3 is provided between the evaporator 4 and the condenser 3. The condenser 3 is located below the evaporator 4, so that the water flows to the condenser 3 under the action of gravity.
