[0025] Figure 3 It is a cross-sectional view of the range hood in the embodiment of the utility model. DETAILED DESCRIPTION

[0026] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] like Figures 1 to 3 As shown, the range hood in this embodiment includes a casing 1 , and a range hood fan 2 and an air conditioning module 3 arranged in the casing 1 .

[0028] The housing 1 can prevent the range hood fan 2 and the air conditioning module 3 from being exposed to the outside, thereby improving the aesthetics of the installation. The specific structure of the housing 11 is determined based on the specific application environment, such as the housing 11 can be additionally provided with a decorative cover or a cabinet in the user's home.

[0029] The oil fume exhaust fan 2 comprises a housing and a fan arranged in the housing. The housing is provided with an oil fume passage. Under the action of the fan, the sucked oil fume can be discharged into the public flue.

[0030] A water box 4 is provided below the air conditioning module 3, and the water box 4 is used to receive the condensed water generated during the use of the air conditioning module 3. After the condensed water is collected in the water box 4, it will not be used or discharged in time, so it is easy to breed bacteria and produce odor. In order to solve this problem, in this embodiment, a sterilization and disinfection module 5 is provided corresponding to the water box 4, and the sterilization and disinfection module 5 is used to sterilize, disinfect and purify the collected condensed water in the water box 4, thereby solving the problems of breeding bacteria and producing odor. The sterilization and disinfection module 5 can adopt various devices in the prior art that can sterilize and disinfect water. Based on the specific type of the sterilization and disinfection module 5, the sterilization and disinfection module 5 can be set in the water box 4; or the sterilization and disinfection module 5 is arranged above the water box 4 facing the water box 4. For example, the sterilization and disinfection module 5 may use an ozone generator, etc. The sterilization and disinfection module 5 in this embodiment adopts an ultraviolet disinfection lamp. To ensure the safety of the ultraviolet disinfection lamp, the ultraviolet disinfection lamp in this embodiment is arranged above the water box 4 facing the opening 21 of the water box 4. Specifically, the ultraviolet disinfection lamp is embedded in the second water receiving tray 36 described below.

[0031] The sterilization and disinfection module 5 will inevitably produce waste gas such as ozone when in use. In order to effectively discharge the waste gas generated by the sterilization and disinfection module 5, the waste gas discharge port of the sterilization and disinfection module 5 is connected to the exhaust channel of the fume exhaust fan 2 through a connecting pipe. In conjunction with the operation of the sterilization and disinfection module 5, the fume exhaust fan 2 can be controlled to operate at a low speed, and then the waste gas generated when the sterilization and disinfection module 5 is in use can be discharged to the public flue through the fume channel of the fume exhaust fan 2.

[0032] In order to timely understand the water quality of the condensed water in the water box 4, a water quality detector is also provided in the water box 4. The water quality detector can adopt various devices capable of realizing water quality detection in the prior art. In this way, it can be determined whether to start the sterilization and disinfection module 5 based on the detection of water quality, thereby improving the unnecessary use of the sterilization and disinfection module 5 and reducing energy consumption accordingly.

[0033] An atomizer 6 is provided near the air outlet in the air flow channel of the air conditioning module 3, and the atomizer 6 is in liquid communication with the water box 4, so that the condensed water in the water box 4 can be atomized and discharged into the use environment of the range hood through the cooperation of the air conditioning module 3 and the atomizer 6. Based on the aforementioned sterilization, disinfection, and purification of the condensed water, the cleanliness of the water mist discharged to the outside can be guaranteed, and the situation that the atomization and discharge of the condensed water damages the health of the user can be avoided. At the same time, based on the atomization and discharge of the condensed water by the atomizer 6, not only the humidity in the use environment of the range hood can be adjusted, but also the problem of the discharge of the condensed water can be solved, and the discharge of the condensed water can be realized without setting up an external drainage pipe.

[0034] In addition, in order to better determine the atomization timing of the condensed water and avoid the damage to the range hood caused by excessive overflow of the condensed water in the water box 4, a water level sensor is provided in the water box 4. When the water level sensor detects that the condensed water level in the water box 4 exceeds the set water level, the atomizer 6 can be controlled to perform atomization, thereby realizing the discharge of the condensed water.

[0035] Based on the simultaneous setting of the water level sensor and the water quality detector, the two can also work together. The water level sensor monitors the water level of the condensed water in the water box 4 in real time. When the water level reaches the set water level, the condensed water processing mode can be turned on. Before turning on the atomizer 6 to atomize the condensed water, the water quality detector is also used to detect the water quality of the condensed water. If the water quality meets the standard, the atomizer 6 can be directly controlled to directly atomize the condensed water in the water box 4. If the water quality does not meet the standard, the sterilization and disinfection module 5 is first used to treat the condensed water in the water box 4, and when the water quality meets the standard, the atomizer 6 is turned on to atomize the condensed water.

[0036] The air conditioning module 3 can adopt the air conditioning structure in the prior art. The air conditioning module 3 in this embodiment includes the basic components such as the evaporator 31, the air outlet assembly 32, the compressor 34, and the condenser 35, and also includes a first water receiving tray 33 and a second water receiving tray 36. The air outlet assembly 32 is connected to the outlet of the air flow channel of the evaporator 31, that is, the air flow output by the air conditioner is discharged to the use environment of the range hood through the air outlet assembly 32. In order to effectively adjust the air outlet direction of the air conditioner, the air outlet assembly 32 includes a frame 321 and a wind guide assembly 322 that is rotatably arranged in the frame 321 to adjust the air outlet direction. The wind guide assembly 322 can include a first swing blade group that can swing up and down and a second swing blade group that can swing left and right, and a driving mechanism is respectively set corresponding to the first swing blade group and the second swing blade group, thereby realizing the up and down drive of the first swing blade group and the left and right drive of the second swing blade group, thereby adjusting the air outlet direction of the air conditioning module 3 in the up and down direction and the left and right direction. The connection relationship between the evaporator 31, the compressor 34, and the condenser 35 is the same as the prior art. The first water receiving pan 33 is arranged below the evaporator 31, and a water leakage hole is provided on the first water receiving pan 33. The compressor 34 and the condenser 35 are arranged below the first water receiving pan 33, and the second water receiving pan 36 is arranged below the compressor 34 and the condenser 35. The second water receiving pan 36 is connected to the water box 4 through a water pipe. When the air conditioning module 3 is working, the first water receiving pan 33 is used to hold the condensed water generated by the evaporator 31. The condensed water generated by the evaporator 31 will flow into the first water receiving pan 33 by gravity. The water leakage hole on the first water receiving pan 33 can be arranged corresponding to the upper part of the condenser 35, so that the water on the first water receiving pan 33 of the evaporator 31 will flow to the condenser 35 through the water leakage hole due to gravity, and directly irrigate and dissipate the heat of the condenser 35. The water that is not evaporated by the condenser 35 will flow to the second water receiving pan 36, and then be introduced into the water box 4 through the water pipe.

[0037] In addition, the air conditioning module 3 will inevitably generate heat when working, and will face the problem of heat dissipation, mainly the problem of heat dissipation of the condenser 35. In order to effectively dissipate heat for the air conditioning module 3, and without setting up an additional heat dissipation mechanism, the fume extractor fan 2 is directly used in this embodiment to dissipate heat for the air conditioning module 3, which is low in cost and small in size. Specifically, the air conditioning module 3 is arranged on one side of the fume extractor fan 2, and an opening 21 is provided on the side wall of the fume extractor fan 2 adjacent to the air conditioning module 3. The heat dissipation air duct of the condenser 35 of the air conditioning module 3 is connected to the opening 21. When the fume extractor fan 2 is working, effective heat dissipation of the condenser 35 can be achieved. However, the opening 21 may affect the internal wind pressure of the fume extractor fan 2. In order to prevent the internal wind pressure of the fume extractor fan 2 from being released and affecting the smoking effect, an opening regulating valve 22 that can adjust the opening of the opening 21 is provided on the opening 21. The opening of the opening 21 is adjusted by the opening regulating valve 22, and the internal wind pressure of the fume extractor fan 2 is guaranteed on the basis of satisfying the heat dissipation of the condenser 35. The opening regulating valve 22 includes a driving motor 221, a shaft rod 222 connected to the driving end of the driving motor 221, and a valve plate 223 connected to the shaft rod 222. During adjustment, the driving motor 221 works to drive the shaft rod 222 and the valve plate 223 to swing, thereby adjusting the angle of the valve plate 223 relative to the opening 21, thereby achieving the purpose of adjusting the opening of the opening 21.

[0038] The range hood in the utility model is provided with a sterilization and disinfection module 5 for the water box 4 for holding condensed water. The sterilization and disinfection module 5 is used to sterilize, disinfect and purify the water in the water box 4, which can solve the problems of bacteria breeding and odor generation in the long-term storage of condensed water, ensure the cleanliness of the condensed water atomized by the atomizer 6 and discharged into the use space of the range hood, and ensure the health and safety of use.
