An air-conditioning indoor unit module is provided on the outside of the upper box body. The upper box body is divided into a smoke exhaust cavity and a heat dissipation cavity. A range hood fan is installed in the smoke exhaust cavity. The heat dissipation cavity is connected with the smoke exhaust cavity through a heat dissipation outlet. A condenser is installed in the heat dissipation cavity. Condensate 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 by the same motor. Condensate 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 body.

[0004] When working in cooling mode, the condenser needs to dissipate heat, so a cooling fan needs to be set up, but this involves more components and is more costly. Utility Model Content

[0024] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0025] like Figures 1 to 6 As shown, the refrigeration range hood of this preferred embodiment includes a body and an air conditioning system arranged on the body, the body includes a lower cavity 1, an upper box body 2 arranged on the top of the lower cavity 1, and a fan system 3 arranged in the upper box body 2, an air inlet 11 is arranged on the lower cavity 1, and the lower cavity 1 is fluidly connected with the upper box body 2. The body can adopt the structure of an existing range hood.

[0026] The air conditioning system includes a compressor 4, a condenser 5 and an evaporator 6, and the three are fluidly connected via a refrigerant pipeline. The working principle of the air conditioning system is the same as that of an existing air conditioner.

[0027] like Figures 4 to 6 As shown, the condenser 5 includes a heat exchange plate 51 and a tube body 52 for the refrigerant to flow through, the tube body 52 is at least partially embedded in the heat exchange plate 51, and a plurality of fins 53 are provided on the heat exchange plate 51 at intervals along the extension direction of the tube body 52. ​​The heat exchange plate 51, the tube body 52 and the fins 53 are all made of copper or other heat exchange materials.

[0028] A plurality of embedded grooves 511 are arranged at intervals along the length direction of the heat exchange plate 51, and each embedded groove 511 penetrates the corresponding side wall surface of the heat exchange plate 51 along the width direction of the heat exchange plate 51. The tube body 52 includes a plurality of straight tubes and U-shaped tubes 521. The straight tubes are embedded in an embedded groove 511 one by one, and the ends of two adjacent straight tubes on the same side are connected by a U-shaped tube 521, so that the tube body 52 extends circuitously, so that the flow path of the tube body 52 in the heat exchange plate 51 is longer, the heat exchange time is longer, and the heat exchange effect is good.

[0029] The greater the height of the fin 53 and the smaller the spacing between adjacent fins 53, the better the heat dissipation effect will be, but the corresponding cost and wind resistance will increase. Conversely, the heat dissipation effect will deteriorate and the cost and wind resistance will decrease. In actual use, the corresponding fin 53 height and fin 53 spacing need to be designed according to actual conditions.

[0030] The condenser 5 is located on the air flow path between the air inlet 11 and the air inlet hole of the fan system 3 , and the fins 53 are located on the front side of the heat exchange plate 51 , so that the air flow will directly flow through the fins 53 , which has a good heat dissipation effect on the fins 53 .

[0031] In order to improve the refrigeration effect of the air conditioning system composed of the compressor 4, the condenser 5 and the evaporator 6, at least two condensers 5 are sequentially arranged along the flow direction of the airflow, and the tube bodies 52 of two adjacent condensers 5 are connected. In this way, there are multiple condensers 5, which can improve the refrigeration effect of the air conditioning system.

[0032] The condenser 5 located at the bottom is arranged in the lower cavity 1, and the heat exchange plate 51 is arranged to be tilted backward from top to bottom. The heat exchange plate 51 of the condenser 5 arranged in the upper box 2 is arranged vertically, so that the heat exchange plate 51 will not block the airflow flowing toward the fan system 3, and the airflow will also flow directly through the condenser 5, which has a good heat dissipation effect on the condenser 5. In this embodiment, Figure 3 As shown, there are two condensers 5, one of which is arranged in the lower cavity 1, and the other is arranged in the upper box 2. Figure 3 The arrow direction is the direction of oil smoke flow.

[0033] An air conditioner inner casing is provided on the upper box body 2, an evaporator 6 is provided in the air conditioner inner casing, a compressor 4 is provided on the top of the lower cavity 1, and the compressor 4, the tube body 52 and the evaporator 6 are fluidically connected via a refrigerant pipeline.

[0034] The range hood also includes a controller. A first temperature sensor (not shown in the figure) is provided on the refrigerant pipeline connected to the compressor 4, and a second temperature sensor (not shown in the figure) is provided on the condenser 5. The first temperature sensor and the second temperature sensor are both electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the fan system 3 (the aforementioned electrical connection methods can all adopt existing methods).

[0035] Since the fumes will invade the condenser 5 during daily cooking, a first temperature sensor and a second temperature sensor are provided. The first temperature sensor is used to detect the temperature of the refrigerant pipeline connected to the compressor 4, and the second temperature sensor is used to detect the temperature of the condenser 5. When the first temperature sensor detects that the temperature is greater than the set value, it sends a signal to the controller, and the controller controls the power of the fan system 3 to reduce the amount of fumes sucked in, that is, to reduce the heat dissipation effect on the condenser 5. When the second temperature sensor detects that the temperature is less than the set value, it sends a signal to the controller, so that the controller continues to reduce the power of the fan system 3 until the second temperature sensor detects that the temperature is greater than the set value. At this time, lard and other oil stains can be melted at high temperature to achieve the cleaning of the condenser 5 and ensure the refrigeration effect of the air-conditioning system.
