Abstract

PURPOSE:To feed air from the adjoining room of a kitchen in order to supply a short feed air quantity, and to make it possible to regulate an air quantity to be fed from the adjoining room while enabling the adjoining room to be ventilated naturally, by controlling a feed air quantity in accordance with an exhaust air quantity and by making the feed air quantity smaller than the exhaust air quantity. CONSTITUTION:In the case where a set temperature by an air-temperature judging means 14 is set at 10 deg.C in the wintertime: if a temperature in adjoining rooms 13 is not lower than 10 deg.C, the quantity of air to be blown out of a blower 8 associated with a heat exchange section 9 is controlled by a controlling means 15 so that 70% of an exhaust air quantity by an exhauster 4 becomes equal to a feed air quantity and, if a temperature in the adjoining rooms 13 is not higher than 10 deg.C, the quantity of air to be blown out of the blower 8 associated with the heat exchange section 9 is controlled so that the feed air quantity is the same as the exhaust air quantity by the exhauster 4. When the cooling is required in the summertime, cold water is supplied to a heat exchanger 7, and the air-temperature judging means 14 sets a temperature so that cold air is fed into a kitchen 2 by a forced air feeding device 11 and further a forced feed air quantity becomes smaller than the exhaust air quantity by the exhauster 4 only when a temperature in the adjoining rooms is below the set temperature.

Description

DETAILED DESCRIPTION OF THE INVENTION FIELD OF INDUSTRIAL APPLICATION The present invention relates to a ventilation system for exhausting oily smoke generated from a range and supplying outside air to ventilate a kitchen.

BACKGROUND OF THE INVENTION As shown in FIG. 6, a conventional ventilation system has a ventilation fan 21 that exhausts oil smoke generated from a range 20, and the operation of the ventilation fan 21 creates a negative pressure in the kitchen 22, reducing the ventilation efficiency of the ventilation fan 21. In order to prevent this, and also because users feel cold when low-temperature outside air is supplied into the room in winter, an air supply fan 24 is provided that supplies air while heating it with a heater 23.

Problems to be Solved by the Invention However, in the above-described configuration, the amount of air supplied by the air supply fan 24 is set to be constant, so when the ventilation fan 21 is switched between strong and weak operations, the pressure in the kitchen 22 changes, causing the ventilation fan to 21
This caused a change in the amount of exhaust air from the air supply fan 24, and the temperature of the air supplied from the air supply fan 24 increased, making it impossible to create a comfortable kitchen space. Furthermore, it was not possible to ventilate rooms adjacent to the kitchen 22 at the same time.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a ventilation system that can naturally ventilate a room adjacent to the kitchen while providing comfort to the user by heating or cooling the kitchen using a forced air supply system. It is something to do.

Means for Solving the Problems In order to achieve the above object, the first means of the present invention is to provide an exhaust device for exhausting oily smoke generated from a range installed in a kitchen, and an exhaust system that exhausts outside air directly or after heat exchange to the kitchen. This device includes a forced air supply device that supplies air, and a control means that controls the amount of air supplied by the forced air supply device in accordance with the amount of exhaust air from the exhaust device.

Further, the second means is provided to operate the control means based on a signal from the temperature determination means that compares and determines the temperature of the room adjacent to the kitchen with the set temperature, and a signal when the exhaust system is in strong or weak operation. be.

Function: With this first means, the outside air supplied to the kitchen by the forced air supply device can be converted into hot or cold air depending on the season, so the kitchen can be heated or cooled, providing comfort to the users. By controlling the supply air volume in accordance with the exhaust air volume and setting the supply air volume to the evening air volume as well as the exhaust air volume, the insufficient supply air volume can be supplied from the room next to the kitchen and the adjacent room can be naturally ventilated. It becomes possible.

In addition, by using the second means, when heating or cooling the kitchen, the amount of air supplied from the adjacent room can be adjusted, so that a large amount of air from the adjacent room with a large temperature difference is not supplied to the kitchen. This means that temperature changes in the kitchen can be reduced.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 3. That is, an exhaust device 4 consisting of a range hood that exhausts oil smoke generated from the range 3 to the outdoors is installed above the range 3 installed in the kitchen 2 provided in the building 1 along with a plurality of rooms, and an exhaust system 4 is connected to the outdoors and is opened when air is supplied. A heat exchange section 9 incorporating a heat exchanger 7 and a blower 8, which performs heat exchange by passing hot or cold water through the interior, is connected to the air supply pipe e provided with the supply air damper 6. A forced air supply device 11 is configured by providing an air outlet 10 on the discharge side of the air blower 9 for blowing air into the kitchen.

Further, a control means 12 is provided which controls the air volume of the blower 8 incorporated in the heat exchanger 9 in accordance with the exhaust air volume based on a signal when the exhaust device 4 is in strong operation or weak operation.

With the above configuration, when the forced air supply device 11 is operated together with the exhaust device 4, the outside air is heat-exchanged into hot air or cold air, and is supplied to the kitchen 2 to heat or cool the kitchen 2, making it comfortable. In addition, the forced air supply device 110 can be created by the control means 12.
By making the forced air supply air volume smaller than the exhaust air volume of the exhaust device 4, the forced air supply air volume becomes insufficient. Air is supplied through gaps between windows, passages, and openings to naturally ventilate the adjacent room 13.

Next, another embodiment of the present invention will be described based on FIGS. 4 and 5.

In other words, the temperature of the adjacent room 13 to which air is supplied is compared with the set temperature, and a signal from the temperature determining means 14 which outputs a signal indicating whether the temperature is above the set temperature or below the set temperature and the operation switch of the exhaust system 4 is set to high operation. A control means 12 is provided which controls the air volume of the blower 8 incorporated in the heat exchanger 9 and gives a signal to open the supply air damper 5 in response to a signal when the air supply damper 5 is operated or a signal when the air supply damper 5 is weakly operated. When the operation of the exhaust system 4 is stopped, the air supply damper 5 is closed and the operation of the forced air supply system 11 is also stopped.

With the above configuration, for example, in winter, when the set temperature of the temperature determination means 14 is set to 10 degrees Celsius, if the temperature of the adjacent room 13 is 10"C or higher, 70% of the exhaust air volume of the exhaust device 4 is The control means 16 so that the supply air volume is
The air volume of the blower 8 incorporated in the heat exchanger 9 is controlled, and if the temperature of the adjacent room 13 is 10°C or less, the exhaust device 4 is
The heat exchange section 9
The air volume of the blower 8 incorporated in the air blower 8 is controlled.

Therefore, when the set temperature of the air temperature determination means 14 is set to 10"C in winter and the temperature of the adjacent room 13 is 10"C or higher, if the user operates the exhaust system 4 with the operation selection switch, the 4 is set, the supply air damper 5 is opened by the control means 16, hot water is supplied from the hot water supply device (not shown) to the heat exchanger 7 of the heat exchange section 9, and the blower 8 is turned on by the exhaust device 4. The air supply air volume is controlled to be 70 cm compared to the exhaust air volume during operation, and outside air is supplied through the air supply pipe 6, heat exchanged with warm air by the heat exchanger 7, and then the air is supplied to the air outlet 1.
Warm air is blown into the kitchen 2 to heat the kitchen 2 so that the user does not feel cold. At this time, forced air device 1
The amount of air supplied by 1 is 70% of the amount of exhaust air, so the amount of air supplied will be 30% short, but there are doors, windows, passages, and openings between the kitchen 2 and the adjacent room 13. Therefore, the insufficient air supply amount ao% is taken in from the adjacent room and
3 natural ventilation will be possible. In addition, since the temperature of the intake air taken in from the adjacent room 13 is higher than the set temperature, the temperature of the intake air taken from the adjacent room 13 is
The temperature of the intake air taken in from No. 3 does not cause a large change in the heating temperature.

In addition, when the temperature of the adjacent room 13 is 10° C. or higher and the exhaust system 4 is operated at low speed, course B is set, and 70% of the exhaust air volume when the exhaust system 4 is operated at low speed is the air supplied by the forced air supply system 11. The insufficient air volume is supplied from the adjacent room 13.

Next, when the temperature of the adjacent room 13 is below the set temperature, the exhaust air volume exhausted from the exhaust device 4 and the supply air volume supplied from the forced air supply device 11 are configured to be the same air volume. Then, when the user operates the exhaust system 4 strongly by operating the operation selection switch of the exhaust system 4, course C is set, and the forced air supply system 11 is operated with the same amount of supply air volume as the exhaust air volume when the exhaust system 4 is operated at high speed. D when the exhaust system 4 is operated at low speed.
The course is set and the forced air supply system 11 is operated with the same amount of supply air volume as the exhaust air volume when the exhaust system 40 is operated,
When the temperature of the adjacent room 13 is below the set temperature, air supply from the adjacent room 13 is removed to prevent the heating effect of the kitchen 2 from decreasing. Furthermore, during the intermediate periods of autumn and spring when heating and cooling are not required, it is sufficient to stop supplying water to the heat exchanger 7 of the forced air supply device 11 and operate only the blower 8 to directly supply outside air.

In addition, although the embodiment explained the state when heating is required in the winter, when cooling is required in the summer, cold water is supplied to the heat exchanger 7, and cold air is supplied to the kitchen 2 from the forced air supply device 11. The same effect can be obtained by setting the temperature determination means so that the forced air flow becomes equal to the evening air flow than the exhaust air flow of the exhaust device 4 only when the temperature of the adjacent room 13 is below the set temperature. It is. Further, although the heat exchanger 7 of the forced air supply device 11 is a heat exchanger that passes hot water or cold water, a heat exchanger corresponding to an indoor unit of an air conditioner or other heat exchanger may be provided. It goes without saying that an opening may be proactively provided to supply air from an adjacent room.

Effects of the Invention As described above, according to the present invention, the supply air volume of a forced air supply device that supplies outside air as it is or after heat exchange to a kitchen equipped with an exhaust system is controlled in accordance with the exhaust air volume. As a result, it is possible to create a comfortable kitchen space by heating or cooling the kitchen, and it is also possible to naturally ventilate the room adjacent to the kitchen by controlling the amount of air supplied.

In addition, a temperature determination means is installed to control the supply air volume by comparing the temperature of the adjacent room that naturally supplies air to the kitchen with the set temperature, so that the temperature of the kitchen that is being heated or cooled can be seen from the adjacent room. Since air with a large temperature difference is not supplied, there will be no sudden changes in the temperature of the kitchen.
