Description

Refrigeration type range hood

Technical Field

The utility model relates to a range hood especially relates to a refrigeration formula range hood.

Background

In order to improve the cooking comfort, people invent various kitchen air conditioners, cool the air in a kitchen in summer and provide warm air for the kitchen in winter. Because the kitchen space is limited, the volume of the kitchen air conditioner cannot be too large, so that the heat dissipation of the kitchen air conditioner has a great problem, and if the heat dissipation cannot be carried out in time in the use process of the kitchen air conditioner, the energy efficiency of the air conditioner can be greatly reduced. However, the existing kitchen air conditioner and the range hood work independently, the two can not be linked, and the heat generated by the kitchen air conditioner can not be discharged to the outside through the fan of the range hood, so that how to discharge the heat generated by the kitchen air conditioner through the range hood becomes a problem to be solved urgently.

The air conditioning assembly is additionally arranged on the basis of the range hood platform, so that all functions of the range hood can be realized, and the function of an air conditioner can be realized. The key point of the structural layout of the air-conditioning range hood is the position arrangement of the condenser. The existing range hood with a refrigeration function adopts the scheme that a condenser is arranged in an oil smoke channel, and air with oil smoke sucked by a fan is utilized for heat exchange; when refrigerating system starts, the wind that the lampblack absorber fan discharges can be blown to the condenser, because contained many oil smoke particles in the wind, in order to keep the condenser surface clean, often need additionally to increase static device and filter these tiny particles, both increased the cost and had the risk of makeing mistakes again. Meanwhile, the inner space of the range hood is relatively narrow, and the requirement on space arrangement is higher. Moreover, the electrostatic device often cannot completely remove oil smoke particles in the wind, so that when the wind of the fan blows to the condenser, the surface of the condenser is polluted, and the working efficiency and the service life of the condenser are reduced. If the condenser is arranged in the smoke exhaust channel, a smoke pipe three-way device is also needed to be added, namely, when the refrigerating system does not work, the air exhausted by the range hood is exhausted out of the normal channel. When the refrigerating system works, the air valve is opened, and the air of the range hood is blown to the condenser through the other channel. Because the paths of wind exhaust under two working conditions need to be considered, and two holes are avoided being drilled on the wall, the wind exhausted by the two paths needs to be finally converged together and exhausted outdoors. The additional tee bend device, for single tobacco pipe cost increase, and because the tobacco pipe is crooked more, be unfavorable for the oil smoke to be discharged. In addition, under the refrigeration mode, outdoor air can blow out cold wind from the air outlet after the heat transfer, and simultaneously, the surface of the evaporator of the internal unit can condense a large amount of condensed water, and at present, the condensed water is directly discharged to the outdoor through the drain pipe and is not effectively utilized.
