Description

Technical Field

[0001] The utility model relates to a range hood, in particular to a cold air outlet duct of a refrigeration-type range hood. Background Art

[0002] Various refrigeration-type range hoods are disclosed in the prior art. An air conditioning module is added to the range hood platform. The air conditioning module includes a compressor, a heat dissipation module and an internal unit module. When working in the refrigeration mode, the internal unit module blows out cold air, which blows toward the cook to enhance the cooking experience. The current integrated kitchen refrigeration range hood generally sets the air outlet on the upper edge of the cabinet door, so that the air outlet is embedded in the cabinet. The air outlet frame needs to be installed separately on the upper edge of the cabinet and cannot be installed together with the range hood. The installation convenience and after-sales maintainability are poor. The air outlet is set on the upper edge of the cabinet door. The air outlet is relatively high. Due to the angle, the user cannot reach the cold air or the cold air blows on the top of the head when standing in front of the range hood, which is less comfortable. In addition, the air outlet is far away from the user, so the user perceives a higher air outlet temperature, no cool feeling, and poor physical examination. As disclosed in the Chinese invention patent application with application number 202110976556.4 (application publication number CN 113566333A), the air conditioning equipment includes an air conditioner, which includes a mounting shell, a first heat exchanger and a second heat exchanger. The first heat exchanger and the second heat exchanger are both mounted in the mounting shell. An air outlet and a flow port are provided on the mounting shell. The air outlet is used to discharge the wind after heat exchange by the first heat exchanger, and the flow port is used to discharge the wind after heat exchange by the second heat exchanger. The connecting pipe has a first connecting port and a second connecting port that are interconnected. The first connecting port is used to communicate with the flow port, and the second connecting port is used to communicate with the exhaust pipe. The air conditioner of the air conditioning equipment adopts a ceiling-mounted mounting structure. The cold air outlet channel is separately arranged from the range hood. The cold air outlet channel needs to be installed independently, with poor integration and inconvenient installation. Moreover, the cold air is blown out through the suspended mounting shell, and the user experience is not good. Utility Model Content
