Description

Technical Field

[0001] This utility model relates to the field of kitchen ventilation and purification technology, and in particular to a heat recovery ventilation fan. Background Technology

[0002] When restaurant kitchens are in use, their range hoods absorb the high-temperature fumes generated during cooking and then exhaust them through ventilation ducts. These high-temperature fumes contain a lot of heat energy, and if they are directly released into the atmosphere, it will not only cause a lot of energy waste, but also lead to environmental problems such as the heat island effect. At the same time, the "white smoke" produced by the condensation of water vapor in the fumes when it encounters cold air will also affect the environment.

[0003] Currently, some kitchens lack heat recovery mechanisms, making it difficult to reuse high-temperature flue gas. This not only wastes energy, but the high-temperature flue gas may also have an impact on the environment. Utility Model Content

[0004] The purpose of this invention is to provide a heat recovery ventilation fan that can solve the problem of the difficulty in reusing high-temperature flue gas, which not only wastes energy but also may have an impact on the environment due to the high temperature of the flue gas.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a heat recovery ventilator, comprising a recovery box, a heating mechanism and an auxiliary mechanism, wherein a fixed side plate is fixedly installed on one side of the recovery box;

[0006] The heating mechanism is located on the recycling bin, and the heating mechanism includes finned heat exchange tubes located inside the recycling bin;

[0007] An auxiliary mechanism is provided on the recycling bin, and the auxiliary mechanism includes a filter box, the inside of which is equipped with a filter plate.

[0010] Preferably, the auxiliary mechanism further includes a fixed block, a U-shaped bracket, a damping limiting spring, a movable plate, a limiting round rod, a pull slide rod, a limiting frame, a support rod, and a baffle. Fixed blocks are fixedly installed on the top and bottom of the filter box. A U-shaped bracket is fixedly installed on one side of the recycling box. A damping limiting spring is fixedly installed on the bottom inner side of the U-shaped bracket. A movable plate is fixedly installed on the bottom of the damping limiting spring. A limiting round rod is fixedly installed on the bottom of the movable plate. A pull slide rod is fixedly installed on the top of the movable plate. One end of the pull slide rod extends to the top of the U-shaped bracket and is fixedly fitted with a handle. The pull slide rod and the U-shaped bracket are slidably installed.

[0014] Compared with existing technologies, the beneficial effects of this utility model are as follows: This heat recovery ventilator, through finned heat exchange tubes, can use the high-temperature flue gas in the kitchen to heat the internal water, fully recovering and utilizing the waste heat that was originally directly emitted. It eliminates the need for additional energy consumption such as gas or electricity to heat water resources, significantly reducing the energy cost of daily hot water use in the kitchen. Simultaneously, it reduces thermal pollution caused by the direct emission of high-temperature flue gas into the environment, meeting the requirements of energy conservation and consumption reduction.

[0024] Working principle: The above-mentioned ventilator 305 is existing technology, and its internal structure and control method do not need to be described in detail. When in use, the flue gas enters the interior of the filter box 401, and then the flue gas is filtered by the filter plate 409. The filtered flue gas enters the interior of the recovery box 1 and heats the water inside the finned heat exchange tube 301. Then it is discharged with the assistance of the ventilator 305. When the filter plate 409 needs to be replaced, pulling the sliding rod 407 moves the movable plate 405 and the limiting round rod 406, which can release the limiting of the fixed block 402 and the U-shaped bracket 403, thus separating the filter box 401 from the recovery box 1.

However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
