According to the present invention, it is characterized in that the exhaust hood guide feather installation, the hood upper and lower, the fan installation, the axial flow of the exhaust duct driving at the same time configured to maximize the exhaust efficiency
Description
The present invention relates to an apparatus for exhausting air by using a canopy hood, in which a hood is installed on an upper portion of a pollution source to collect and discharge a large amount of heat and polluted air due to an upward airflow to an upper canopy hood.
The characteristic of the canopy-type hood is that it is suitable for the place where hot rising air flows, and the efficiency is drastically reduced if there is no rising air flow. The intake port surrounding the whole or surrounding part of the source is called a hood, and the air flow at Guide it to the hood and exhaust it
It is a method that requires attention to use because it is easy for the worker to breathe the dirty air by working under the hood opening. In general, the exhaust hood of a general kitchen uses a canopy hood and is produced when cooking with a cooking device that uses heat in the kitchen. Hot air and rapid discharge of various polluted air have been a problem, and the prevention of polluted air diffusion is closely related to the surrounding airflow.
In some parts of existing kitchens, some places provide air conditioning air to the cooking workers by spot cooling. However, in the kitchen, air conditioning is not possible. After a rapid bacterial breeding, the food in the kitchen may be damaged, and the cooked food or food ingredients may be deteriorated. Therefore, the food materials used should be frozen and refrigerated immediately after preparation.
The canopy hood is a hood that uses hot rising air flow. A horizontal siro nose is installed on each side of the heat source device to maximize the suction efficiency when collecting and exhausting air. Phosphorus-contaminated air is sucked into the end of the hood and moved to the exhaust duct by an airflow guide guide installed inside the hood, and the centrifugal axial flow fan is simultaneously combined with the hood and the exhaust duct to move it out quickly.
At this time, if the discharge air flow angle is adjusted in consideration of the discharge diffusion angle of the outlet airflow of the horizontal sirocco 설치된 installed on one side of the lower heat source device, the polluted air is not diffused to the outside and the entire air is sucked into the end of the upper hood. Will solve
The present invention was created in order to solve the above-mentioned problems in the prior art, by using air curtains to contaminate air diffused to the outside of the hood while pressurizing in the same direction as the upward air flow to the lower air discharge. It is an object of the present invention to provide a suction device that can be collected toward the exhaust hood to increase the exhaust efficiency.
The device configuration is simple and can be installed regardless of the shape of the exhaust port. It can be used in existing equipment without additional equipment and can be used to save money and can be used in factories, homes, restaurants, and large kitchens that generate a lot of pollutants.
In order to solve this problem, the present invention canopy hood exhaust device by installing a horizontal siro nose in the side of the heat source device to adjust the angle so that the air diffusion distance of the air curtain discharged from the discharge port falls within the upper siro nose suction radius Essentially, the air curtain should be adjusted to the optimum angle by the angle adjusting sensor installed on the upper and lower sides. If the angle of the air curtain is installed out of the diffusion angle, the heated contaminated air diffuses rapidly into the room. Adjusting the airflow of the air curtain is characterized in that it can prevent the spread of contaminated air to the outer periphery of the hood.
Simultaneously operating the upper and lower sirocco 휀 and the centrifugal axial flow 의 of the exhaust duct connection, the contaminated air moves to the upper hood and the contaminated air moved by the guide vane installed inside the hood is connected to the exhaust duct. It is characterized in that it can be discharged quickly by the centrifugal axial flow fan of the inlet
In addition, a sensible heat exchanger is installed at the exhaust duct connection to recover waste heat of a large amount of contaminated hot air, and is used as a preheating load for hot water heating to recycle energy.
As described above, the canopy hood exhaust device of the present invention has the effect of creating a comfortable space by collecting the exhaust air flow and contaminated air from the source of the contaminant in a general kitchen or factory toward the upper hood to exhaust the condensed air.
By using the present invention, high temperature polluted air is not diffused, and the number of ventilation can be significantly reduced, thus reducing the capacity of the kitchen ventilation fan and installing a sensible heat exchanger to recover waste heat of a large amount of contaminated hot air at the exhaust duct connection. By using it as preheating load for hot water heating, energy is recycled and deodorizing unit is installed at the end of duct to prevent odor spreading to the outside.
The unit is equipped with a unit cooler to enable the worker to spot air conditioner or the entire air conditioner in the kitchen.
It is a facility that can reduce energy and save energy, which is the government's recommended standard for green products.
