2. Description of the Related Art In recent years, in blower type heaters that circulate and heat the air inside and outside the equipment, when the circulating air is sucked into the equipment, the air outside the equipment is removed after removing dirt such as cigarette particles from the air. The equipment with an air purifying function that is sent to the factory has been well received in terms of improving the indoor environment.

For example, FIG. 6 is a block diagram of a gas warm air heater with an air cleaner. The device exterior 1 and the base 2 separate the device from the outside, and the device outside air is sucked in through the outside air intake port 14 by the operation of the circulation device 7 having the blower fan 6 driven by the motor 5. The air drawn into the equipment is the air cleaning device 1
After passing through 1 and passing through a combustion chamber 10 (hereinafter referred to as a heat exchange device 10) configured by a heat exchanger 9 and a burner 9 that heats air, it is blown out of the equipment. When the circulating air passes through the equipment, it is collected and heated, and returned to the room again to heat the room and clean the air. At this time, the air purifying device mounted on the warm air heater needs to reduce the air passage resistance in order to ensure combustion performance, and is generally of the electric dust collecting type.

Reference numeral 3 in FIG. 6 denotes an operation section of the device,
Although not shown, an operation switch for heating the equipment and an operation switch for the air cleaning function are provided. By these operations, it is possible to select and use the independent operation of heating and the simultaneous operation of heating and air cleaning during heating in winter, and the independent operation of air cleaning during the season when heating is not required.

FIG. 7 shows a block diagram of a conventional combustion control device. The temperature control unit 16 determines the operation amount during the heating operation based on the signals from the temperature setting unit 15 and the temperature detection unit 4. Reference numeral 17 is a combustion amount control unit, which is based on the above-mentioned operation amount.
Determine the control amount of.

Reference numeral 18 denotes a circulating air amount control unit at the time of heating, which determines the control amount of the circulation device 7 based on the operation amount. During the heating operation, the heat exchange device 10 and the circulation device 7 are
Regardless of whether or not the air cleaning operation is performed, combustion performance is prioritized and operation is performed according to the above control amount.

On the other hand, reference numeral 19 denotes a circulating air amount control unit during an air purifying independent operation, and controls the circulating device 7 via a switch 20 which judges the air purifying independent operation and switches to the circulating air amount control unit 19. . That is, during the air-cleaning independent operation, the circulation device 7 operates with priority on the air-cleaning performance. Here, the circulating air amount control unit 1 during the air-cleaning independent operation
The setting of 9 is set to the maximum control amount (circulation air amount at the time of maximum combustion) so as to secure a large amount of circulation air and increase the amount of intake air to the device in order to improve the air purification characteristics.

[0008]

However, in the conventional air-cleaning independent operation, the circulation device 7 operates while maximizing the circulation air amount in order to prioritize the air-purifying performance, and the heat exchange device 10 is stopped. . In the seasons other than winter, when the air purifying function is used as an independent operation and where heating is not required, in relatively cool seasons such as late autumn and early spring, heating the air that is not heated can cause discomfort due to cold air. Occurs.

[0009] Normally, the circulating air amount depends on the heating capacity of the equipment. At the maximum circulating amount of 2000 kcal (for 6 tatami mats), about 2 m ³ / min, 3000 kcal (for 8 tatami mats).
Then, about 2.5-3 m ³ / min, 5000 kcal (12
For tatami mats) it is about 4-5 m ³ / min. Considering the air cleaning performance and the feeling of cool air due to the circulating air, it is considered that the amount of circulating air during the air cleaning single operation is preferably about 2 m ³ / min.

An object of the present invention is to provide a heater with an air cleaning function that reduces the discomfort caused by the feeling of cold air due to the circulating air during the air cleaning independent operation and can be used comfortably throughout the year.

[0011]

The first means for achieving the above object of the present invention is a circulation device for circulating the air inside and outside the equipment, a heat exchange device for heating the air inside the equipment, and an air for purifying the circulation air. A cleaning device, an air cleaning switch that operates / stops the air cleaning function, and an air circulation rate of about 2 m ³ / min in the circulation device when operating with the air cleaning function alone, and a circulation device to eliminate the feeling of cold air due to the circulating air. And a circulating air amount control unit for controlling.

The second means is a circulation amount setting unit for arbitrarily setting the air circulation amount of the circulation device when operating with the air cleaning function alone, and the circulation device according to the set value in the circulation amount setting unit. And a circulating air amount control unit for controlling.

The third means is provided with a temperature detection sensor for detecting the air temperature, and a circulating air amount control section for controlling the circulation device according to the temperature detected by the temperature detection sensor when the air cleaning function alone is operated. Be prepared.

According to the first aspect of the present invention, when the device is operated with the air cleaning function alone, the circulation amount setting section during the air cleaning independent operation circulates regardless of the heating capacity of the device. Since the amount of air is set to about 2 m ³ / min, it is possible to reduce the feeling of cold wind due to the circulating air even in the relatively cool late autumn and early spring.

Further, according to the second means, when the equipment is operated by the air cleaning function alone, the circulation amount setting device capable of arbitrarily setting the circulation amount of the circulation device circulates the circulation according to the preference of the user. The amount of air can be changed, and in late autumn and early spring when it is relatively cool, setting a small amount of circulation can reduce the feeling of cold air due to circulating air, and in the hot summer months, the amount of circulation can be increased. Even if set, the air cleaning performance can be sufficiently exhibited.

Further, according to the third means, when the equipment is operated solely by the air cleaning function, the temperature of the circulating air is detected by the sensor for detecting the temperature in the room where the equipment is installed, and the temperature is measured according to the room temperature. The amount of circulating air can be controlled by controlling the amount of circulating air in late autumn or early spring when it is relatively cool.
Further, in the hot summer season, the air purification performance can be sufficiently exerted even if the circulation amount is controlled to be large.
