Description

Technical Field

[0001] The utility model relates to a range hood, in particular to an air outlet structure 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, and the cold air blows toward the cook to enhance the cooking experience. Some refrigeration range hoods set the cold 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. Some refrigeration-type range hoods also have the cold air outlet located at the bottom of the range hood. In this case, an air duct connection is required from the indoor unit to the outlet. The existing connection air outlet generally adopts a sheet metal duct structure surrounded on all sides, which requires welding and polishing, has many processes, and has high labor costs. In addition, it needs to be assembled with the air outlet and the indoor unit during installation, has high tolerance requirements, and is more troublesome to install. In addition, cold loss is likely to occur if the thermal insulation cotton is not properly pasted. Utility Model Content
