Description

Technical Field

[0001] This utility model relates to a kitchen ventilation and smoke extraction device, and more particularly to an air-conditioning type range hood. Background Technology

[0002] An air-conditioning range hood adds an air conditioning component to a standard range hood platform, thus combining the functions of both a range hood and an air conditioner. In existing technologies, the air conditioning and fume extraction components are typically distributed. For example, patent document CN111288545A discloses an air-conditioning range hood where the air conditioning component includes a first and second housing, and the fume extraction component includes a fan frame. The first and second housings are isolated from each other and located on the left and right sides of the fan frame, respectively. A first heat exchanger and a second heat exchanger are installed inside the first and second housings, respectively. The fan removes heat from the first heat exchanger, and the air, after being heated by the second heat exchanger, is delivered to the kitchen through an exhaust fan. This distributed layout results in a loose overall structure, occupying more space and increasing installation difficulty. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a compact air-conditioning type range hood.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A compact air-conditioning type range hood includes a housing and a smoke collection hood installed at the bottom of the housing. An inner shell is installed inside the housing, with a smoke chamber formed on the inner side of the inner shell and a cooling chamber formed on the outer side of the inner shell. A cooling device is installed in the cooling chamber. The housing is provided with an air conditioning inlet communicating with the cooling chamber and an air conditioning outlet communicating with the cooling device. A cooling fan and a smoke extraction fan are installed in the smoke chamber. The air inlet of the cooling fan communicates with the cooling chamber, and the air inlet of the smoke extraction fan communicates with the smoke outlet of the smoke collection hood. An exhaust hood is installed at the upper end of the inner shell, with the air inlet of the exhaust hood communicating with the air outlets of the cooling fan and the smoke extraction fan.

[0006] The refrigeration device includes a compressor, a condenser, and an evaporator. The front end face of the inner shell is provided with a heat dissipation air inlet that communicates with the air inlet of the heat dissipation fan. The condenser is installed on the outside of the heat dissipation air inlet.

[0007] A water collection tank is installed at the lower end of the condenser, an atomizing generator is installed in the water collection tank, and a water level sensor is installed on the inner wall of the water collection tank.

[0008] A flow guide groove is installed on the top upper side of the inner shell. An evaporator, an air outlet fan, and an air guide shroud are installed sequentially from back to front on the upper end of the flow guide groove. After assembly, the air outlet of the air guide shroud extends out of the air conditioner outlet.

[0009] The bottom front end of the guide channel is provided with several through holes corresponding to the upper end of the condenser.

[0010] Both the cooling fan and the fume extractor are centrifugal fans. The air inlet of the cooling fan is in the opposite direction to the air inlet of the fume extractor. After assembly, the rear end face of the cooling fan is attached to the front end face of the fume extractor.

[0011] The upper end of the inner shell is provided with an inner shell air outlet that communicates with the air inlet of the air outlet hood. After assembly, the air outlets of the cooling fan and the fume extractor fan extend out of the inner shell air outlet, respectively.

[0012] The air outlet cover includes a cover body and blades disposed inside the cover body. The lower end of the cover body is fixedly connected to the inner shell, and the upper end is fixedly connected to the inner side of the top of the box body.

[0013] The blade includes a first blade and a second blade. The first blade has a first circular hole at each end, and the second blade has a second circular hole at each end. After assembly, one end of the rotating shaft passes through the first circular hole and the second circular hole, and the other end is connected to the cover.

[0014] The cover has an inwardly protruding annular limiting part in the middle. After assembly, the bottoms of the first blade and the second blade abut against the annular limiting part.

[0015] The beneficial effects of this utility model are as follows: An inner shell is installed inside the housing, forming an oil fume chamber on the inner side of the inner shell and a cooling chamber on the outer side of the inner shell. Installing both the oil fume chamber and the cooling chamber within a single housing improves space utilization. Furthermore, a cooling fan and an oil fume extraction fan are installed within the oil fume chamber. The air inlet of the cooling fan is connected to the cooling chamber, and the air inlet of the oil fume extraction fan is connected to the oil fume outlet of the smoke collection hood. The air outlets of both the cooling fan and the oil fume extraction fan are connected to the air inlet of the exhaust hood. This allows the air dissipated by the cooling fan and the oil fumes extracted by the oil fume extraction fan to be discharged through a single exhaust hood, sharing a common air duct. This reduces assembly difficulty and space requirements, resulting in a more compact overall structure. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0026] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0027] The following describes some embodiments of the present invention with reference to the accompanying drawings.

[0028] Reference Figures 1 to 8A compact air-conditioning type range hood includes a housing 1 and a smoke collection hood 2 installed at the bottom of the housing 1. An inner shell 3 is installed inside the housing 1. An oil fume chamber is formed on the inner side of the inner shell 3, and a cooling chamber is formed on the outer side of the inner shell 3. A cooling device is installed in the cooling chamber. The housing 1 is provided with an air conditioning inlet 11 communicating with the cooling chamber and an air conditioning outlet 12 communicating with the cooling device. A cooling fan 31 and a smoke extraction fan 32 are installed in the oil fume chamber. The air inlet of the cooling fan 31 communicates with the cooling chamber, and the air inlet of the smoke extraction fan 32 communicates with the oil fume outlet of the smoke collection hood 1. An exhaust hood 5 is installed at the upper end of the inner shell 3, and the air inlet of the exhaust hood 5 communicates with the air outlets of the cooling fan 31 and the smoke extraction fan 32. In this invention, both the fume chamber and the cooling chamber are installed inside the housing 1, thereby improving the space utilization rate. In addition, the cooling fan 31 is installed in the fume chamber, so that the air dissipated by the cooling fan 31 and the fumes sucked by the fume extraction fan 32 are discharged from the same exhaust hood and share the same air duct. This reduces the assembly difficulty and the space occupied, making the overall structure more compact.

[0029] The refrigeration device includes a compressor 41, a condenser 42, and an evaporator 43, which are connected by refrigerant piping. The front end of the inner shell 3 has a heat dissipation air inlet 33 that communicates with the air inlet of the cooling fan 31. The condenser 42 is installed outside the heat dissipation air inlet. In this embodiment, a water collection tank 44 is installed at the lower end of the condenser 42. An atomizing generator 45 is installed in the water collection tank 44, and a water level sensor 46 is installed on the inner wall of the water collection tank 44. A guide channel 61 is installed on the upper top of the inner shell 3. From back to front, the evaporator 43, the outlet fan 62, and the air guide shroud 63 are sequentially installed on the upper end of the guide channel 61. After assembly, the air outlet of the air guide shroud 63 extends out of the air conditioning outlet 12. Several through holes are provided at the bottom front end of the guide channel 61 corresponding to the upper end of the condenser 42. In cooling mode, fresh air enters the cooling chamber through the air inlet 11 of the air conditioner. The heat generated by the condenser 42 is carried away by the cooling fan 31. At the same time, the condensate on the evaporator 43 flows into the condenser 42 through the through hole of the guide groove 61, thereby cooling the direct condenser 42. Some of the condensate flowing through the condenser 42 will flow into the water collection tank 44. The atomizer 45 will convert the condensate into cold mist, further cooling the condenser 42 and improving the heat dissipation effect of the condenser. When the water level sensor 46 detects that there is too much condensate in the water collection tank 44, it can be pumped out by the water pump 35 installed on one side of the inner shell 3 to prevent the condensate from overflowing.

[0030] As a further improvement of this utility model, both the cooling fan 31 and the fume extraction fan 32 are centrifugal fans. The air inlet of the cooling fan 31 is opposite in direction to the air inlet of the fume extraction fan 32. After assembly, the rear end face of the cooling fan 31 is attached to the front end face of the fume extraction fan 32, resulting in a simple and compact assembly structure. In this embodiment, the cooling fan 31 and the fume extraction fan 32 can be driven by separate motors or share a single motor. Compared to sharing a motor, patent document CN119123490A discloses a refrigerated fume extraction fan, whose disclosed technology includes the cooling fan and the fume extraction fan rotating synchronously under the drive of a motor.

[0031] The upper end of the inner shell 3 is provided with an inner shell air outlet 34 that communicates with the air inlet of the air outlet hood 5. After assembly, the air outlets of the cooling fan 31 and the fume extractor 32 extend out of the inner shell air outlet 34, respectively. The air outlets of the cooling fan 31 and the fume extractor 32 share a single air outlet hood 5, which reduces space requirements and makes the overall structure more compact.

[0032] The exhaust hood 5 includes a hood body 51 and blades disposed within the hood body 51. The lower end of the hood body 51 is fixedly connected to the inner shell 3, and the upper end is fixedly connected to the inner top of the housing 1. In this embodiment, the exhaust hood 5 is hidden inside the housing 1, which improves the aesthetics and allows for direct connection to the top of the housing 1 when installing the exhaust duct, facilitating assembly.

[0033] The blades include a first blade 52 and a second blade 53. The first blade 52 has a first circular hole at each end, and the second blade 53 has a second circular hole at each end. After assembly, one end of the rotating shaft 54 ​​passes through the first and second circular holes, and the other end is connected to the cover 51. The cover 51 has an annular limiting portion 55 protruding inwards from its center. After assembly, the bottoms of the first blade 52 and the second blade 53 abut against the annular limiting portion 55.
