Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0066] like Figure 1 and Figure 2 As shown, this embodiment provides an air-conditioned range hood 1. The air-conditioned range hood 1 comprises a range hood assembly 10 and an air-conditioning assembly 20, wherein the range hood assembly 10 is used to realize the oil fume suction function; and the air-conditioning assembly 20 is used to realize the air-conditioning function.

[0067] The air-conditioning range hood 1 further includes a housing 30, and the air-conditioning assembly 20 is installed in the housing 30. It should be noted that in order to better illustrate the structure of the components located inside the housing 30, Figure 1 What is shown in FIG. 3 is the internal structure of the housing 30 .

[0068] The air conditioning assembly 20 includes a compressor 21 and an evaporator 22, which are connected via a refrigerant pipe 23. The air conditioning assembly 20 also includes a first heat exchange cooling branch 241 and a second heat exchange cooling branch 242, which are respectively connected to the refrigerant pipe 23. Figure 2 As shown in the figure, the flow direction of the refrigerant in the refrigerant pipeline 23 is represented by a single arrow, the flow direction of the refrigerant in the first heat exchange cooling branch 241 is represented by superimposed double arrows, and the flow direction of the refrigerant in the second heat exchange cooling branch 242 is represented by superimposed three arrows.

[0069] A condenser 251 is provided on the first heat exchange cooling branch 241, and the refrigerant entering the condenser 251 is subjected to heat exchange cooling through a heat dissipation fan 252 provided corresponding to the condenser 251; a heat exchanger 253 is provided on the second heat exchange cooling branch 242, and the refrigerant entering the heat exchanger 253 is subjected to heat exchange cooling with the water flowing into the heat exchanger 253 from the water inlet pipe 27, and the end of the water inlet pipe 27 away from the heat exchanger 253 is connected to an external pipe; wherein, the refrigerant pipe 23 is used to be connected to the second heat exchange cooling branch 242 when the instantaneous temperature of the water flow in the water inlet pipe 27 is lower than the set temperature; and to be connected to the first heat exchange cooling branch 241 when the instantaneous temperature of the water flow in the water inlet pipe 27 is not lower than the set temperature.

[0070] Thus, by providing two different heat exchange cooling branches, when the instantaneous temperature of the water flow in the water inlet pipe 27 is lower than the set temperature, the refrigerant pipe 23 can be switched to connect with the second heat exchange cooling branch 242, and the water flow in the water inlet pipe 27 can be used to exchange heat and cool the refrigerant. This avoids the use of the heat dissipation fan 252 on the first heat exchange cooling branch 241 for air cooling, thereby reducing the hot air generated by the air cooling method, thereby reducing the impact on the oil fume extraction effect of the air-conditioning range hood 1 and reducing the noise generated. It should be noted that the heat exchanger 253 realizes heat exchange between the refrigerant (i.e., refrigerant) and the water flow in the water inlet pipe 27, heating the water flow in the water inlet pipe 27 to a certain temperature to provide hot water for the user. The water inlet pipe 27 is connected to an external pipe. In other words, the temperature of the water flow in the water inlet pipe 27 is positively correlated with the external ambient temperature, increasing with increasing external ambient temperature and decreasing with decreasing external ambient temperature.

[0071] Preferably, the set temperature is 45 degrees. Thus, by setting the set temperature to 45 degrees, when the instantaneous temperature of the water flow in the water inlet pipe 27 is lower than 45 degrees, the refrigerant pipe 23 is connected to the second heat exchange cooling branch 242; when the instantaneous temperature of the water flow in the water inlet pipe 27 is not lower than 45 degrees, the refrigerant pipe 23 is connected to the second heat exchange cooling branch 242, so as to maximize the use of the water flow in the water inlet pipe 27 to cool the refrigerant.

[0072] In this embodiment, the air conditioning assembly 20 further includes a controller, a first electric switching valve 261, and a second electric switching valve 262. The first electric switching valve 261 is located upstream of the second electric switching valve 262 in the direction of refrigerant flow, and both the first electric switching valve 261 and the second electric switching valve 262 are electrically connected to the controller. The upstream side of the first electric switching valve 261 in the direction of refrigerant flow is connected to the refrigerant pipeline 23, and the downstream side is connected to the first heat exchange cooling branch 241 and the second heat exchange cooling branch 242, respectively. The upstream side of the second electric switching valve 262 in the direction of refrigerant flow is connected to the first heat exchange cooling branch 241 and the second heat exchange cooling branch 242, respectively, and the downstream side is connected to the refrigerant pipeline 23. Thus, by providing the first electric switching valve 261 and the second electric switching valve 262, the refrigerant pipeline 23 can be switched between communication with the first heat exchange cooling branch 241 and communication with the second heat exchange cooling branch 242. The controller, the first electric switching valve 261 and the second electric switching valve 262 are all commercially available products.

[0073] A temperature sensor 281 is provided on the water inlet pipe 27. The temperature sensor 281 is used to detect the instantaneous temperature of the water flowing in the water inlet pipe 27. The temperature sensor 281 is electrically connected to the controller. Thus, the temperature sensor 281 is provided to detect the instantaneous temperature of the water flowing in the water inlet pipe 27. The temperature sensor 281 is a commercially available product.

[0074] A first water pump 282 is provided on the water inlet pipe 27. The first water pump 282 is configured to direct water from the water inlet pipe 27 to the heat exchanger 253. The first water pump 282 is electrically connected to a controller. Thus, the first water pump 282 provides power for the flow of water within the water inlet pipe 27. The first water pump 282 is a commercially available product.

[0075] A one-way valve 283 is installed at the end of the water inlet pipe 27 near the external pipe. This valve is used to prevent water from flowing back from the water inlet pipe 27 to the external pipe. The one-way valve 283 is electrically connected to the controller. Thus, the installation of the one-way valve 283 prevents water from flowing back from the water inlet pipe 27 to the external pipe. The one-way valve 283 is a commercially available product.

[0076] In this embodiment, the outlet of the heat dissipation fan 252 communicates with the inner cavity of the volute of the range hood fan 11 of the range hood assembly 10. By arranging for the outlet of the heat dissipation fan 252 to communicate with the inner cavity of the volute of the range hood fan 11, the air generated by the heat dissipation fan 252 after passing through the condenser 251 can be discharged into the common flue through the range hood volute and the smoke pipe, eliminating the need for a separate exhaust pipeline, thereby achieving the beneficial technical effect of simplifying the structure.

[0077] The range hood assembly 10 further includes a hood 12 , which is located below the housing 30 . The hood 12 is provided with an air inlet cavity connected to the range hood fan 11 , and an air inlet is provided on a side of the air inlet cavity away from the housing 30 .

[0078] The air conditioning assembly 20 also includes an indoor fan 29, which is positioned corresponding to the evaporator 22 and is used to blow the air after heat exchange with the evaporator 22 out of the housing 30 of the air conditioning range hood 1. An air outlet 201 connected to the indoor fan 29 is formed on the end of the hood 12 near the housing 30, facing the user.

[0079] In this embodiment, the condensed water condensed on the evaporator 22 is collected and transported to the top of the condenser 251 through the water transfer channel 41, where it is evaporated by heat exchange with the condenser 251. Thus, by providing the water transfer channel 41 that transports the condensed water condensed on the evaporator 22 to the top of the condenser 251, the condensed water is evaporated by heat exchange with the condenser 251, eliminating the need to discharge the condensed water. This avoids the risk of condensed water corroding the user's external wall and dripping into the external environment. Furthermore, by utilizing the heat exchange and evaporation of the condensed water, the condensation function of the condenser 251 is improved.

[0080] The air conditioning range hood 1 also includes a water storage box 42 and a second water pump 43 installed in the water storage box 42. A water supply channel 41 connects the water storage box 42 with the top of the condenser 251, and the second water pump 43 is located at the end of the water supply channel 41 near the water storage box 42. The water storage box 42 is used to collect condensed water condensed on the surface of the evaporator 22. The second water pump 43 is used to pump the condensed water in the water storage box 42 through the water supply channel 41 to the top of the condenser 251. In this way, the water storage box 42 is provided to collect condensed water condensed on the surface of the evaporator 22, and the water pump is provided to pump the condensed water in the water storage box 42 through the water supply channel 41 to the top of the condenser 251.

[0081] The condenser 251 is located within the housing of the heat dissipation fan 252. The air conditioning range hood 1 also includes a water return channel 44, which connects the bottom of the housing and the water storage box 42. Unevaporated condensed water is collected at the bottom of the housing. Thus, by providing a water return channel 44 connecting the bottom of the housing and the water storage box 42, unevaporated condensed water is recovered to the water storage box 42, making it easier to later transport this condensed water to the top of the condenser 251 for the next round of heat exchange and evaporation.

[0082] This embodiment sets up two different heat exchange cooling branches. When the instantaneous temperature of the water flow in the water inlet pipe 27 is lower than the set temperature, it can switch to the refrigerant pipe 23 to connect with the second heat exchange cooling branch 242, and use the water flow in the water inlet pipe 27 to perform heat exchange cooling on the refrigerant, thereby avoiding the use of the heat dissipation fan 252 on the first heat exchange cooling branch 241 for air cooling. The hot air generated by the air cooling method is reduced, thereby reducing the impact on the oil fume suction effect of the air-conditioning range hood 1 and reducing the noise generation.

Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, and such changes and modifications are intended to fall within the scope of protection of the present invention.
