Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a waste heat recovery type ventilation device having a kitchen air supply and an air cleaning function,

In the present invention, waste heat is recovered from the indoor air heated and discharged through the heat exchanger when the temperature difference between indoor and outdoor is large, and by discharging indoor air by bypassing the indoor air when the temperature difference is small, The present invention relates to a ventilation device for improving the cleanliness of air by exchanging air of an indoor air inlet and an indoor air outlet, and more particularly, to a ventilation device having an outdoor air outlet and an indoor air outlet on both sides of a heat exchange element, A second housing provided with a filter between the outer air inlet and the air supply fan, a bypass pipe connected between the first housing and the second housing, and an exhaust pipe connected to the exhaust fan, An air clean chamber in which a air inlet and a filter are spaced apart from each other and a space is formed inside the second housing, an indoor air outlet and an air clean chamber are connected to each other And an air purifying damper for controlling opening and closing of the air purifying pipe and an outside air introducing damper for blocking the outside air inlet, and a waste heat recovering type ventilator having an air purifying function.

Generally, when food is heated and cooked, not only odor but also fine dust and harmful gas are generated together. Such fine dust and harmful gas cause various respiratory diseases. Therefore, in the kitchen of the house, A fan mounted inside the hood and equipped with a kitchen ventilation system for discharging fine dust, harmful gas and odor generated during cooking.

Also, in order to maintain the temperature, humidity, and cleanliness of the indoor air of the building in an optimal state, a ventilation system for introducing outdoor air into the room and discharging the indoor air to the outside is installed. The system is constructed separately from each other, and the installation cost is increased, and there is a problem that the space can not be utilized properly due to the installation of the ducts which become the passage of the air.

In order to solve the above problems, Korean Patent Registration No. 10-1704353 (Registered on Feb. 21, 2017) discloses a system for introducing outdoor air through an air supply fan to a supply pipe connected to a lower portion of a countertop, A kitchen air supply diffuser for discharging indoor air and a structure of a kitchen ventilation interlocking system using the same are disclosed. However, such a kitchen ventilation interlocking system has a problem in that when indoor and outdoor temperature differences are large, such as summer or winter, There is a problem that the heat energy loss due to the temperature difference of the indoor and outdoor air exchanged as the outdoor air is introduced into the room increases.

To solve these problems, Korean Patent Registration No. 10-1827730 (Registered on Feb. 28, 2015) discloses an air conditioner which is installed in an indoor space, And a partition wall formed between the air supply fan for supplying outdoor air to the room and the exhaust fan for discharging indoor air to the outside, The air cleaner filter and the air cleaner damper are installed in the air cleaner damper so that the air supply and exhaust operation for exchanging indoor and outdoor air according to the opening and closing control of the air clean damper and the indoor air cleaning operation are selectively generated, · Waste heat recovery type ventilation system that can save energy used for heating is proposed.

However, when the kitchen is cooked, fine dust and harmful gas are generated, and the cycle of executing the air cleaning is different from that of other indoor spaces. In the above-mentioned waste heat recovery type ventilation system, when the ventilation system is operated for the kitchen ventilation, The amount of air that can be ventilated in the kitchen is reduced as much as the amount of air that is ventilated in the other indoor space from the total amount of air that the exhaust fan can ventilate the indoor air, The efficiency is reduced and the filters that filter the foreign substances such as dust contained in the air during the air supply operation and the air cleaning operation are divided into the air supply filter and the air cleaning filter respectively and thus the cleanliness of the ventilation system such as the filter cleaning and exchange is maintained There was difficulty in management.
