Abstract

(57) [Abstract] [Purpose] Realize a warm air heater that quickly provides comfortable heating. [Structure] Only when the heating operation is started only once, and only when the room temperature detected by the thermistor 1 is equal to or lower than a predetermined value (for example, 10 ° C.), a certain time from the start of the heating operation, or If the thermistor 1 detects the above-mentioned predetermined room temperature within a certain period of time,
The maximum output of the heating element 3 in the steady state (eg 3,200 kcal /
h) A hot air heater is configured by a microcomputer that controls the operation with a larger maximum output of 3,500 kcal / h).

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a warm air heater.

[0002]

[Prior art]

 Conventional hot air heaters have improved the heat collection performance by performing strong operation for a certain period of time (for example, 3 minutes) after ignition regardless of the room temperature at the start of heating operation, and by changing the wind direction plate or air volume. .

[0003]

[Problems to be solved by the device]

 However, with this operation control, the temperature of the room air may not rise easily with only the amount of heat of strong operation, and this was particularly noticeable when the temperature was low in the middle of winter. Also, even if the temperature of the air in the room rises, there is a problem that real comfort cannot be obtained unless the temperature of the load on the floor, walls, windows, etc. rises. In response, if the heating output is controlled from strong (3,200kcal / h) to medium (2,500kcal / h), weak (1,800kcal / h) and minute (1,100kcal / h), There was a drawback that the discomfort could not be removed until the temperature of the floor, walls, windows, etc., of the building did not rise sufficiently.

[0004]

[Means for Solving the Problems]

 The present invention has been made to solve the above-mentioned problems, and in a warm air heater in which the heating output of the heating element is controlled based on the room temperature information detected by the temperature detecting means, at the beginning of heating operation. Only once, and only when the room temperature detected by the temperature detecting means is less than or equal to a predetermined value, the temperature detecting means is set to a predetermined time or within a certain time from the start of the heating operation. When the room temperature is detected, the hot air heater is configured with a control means that controls the operation of the heating element with a special maximum output that is larger than the maximum output during the steady state until then.

[0005]

[Action]

 With this configuration, the heating element starts the heating operation only once at the beginning of the heating operation, and only when the room temperature detected by the temperature detecting means is below a predetermined value. The drive is controlled with a special maximum output that is larger than the maximum output during the steady state for a fixed period of time, or when the temperature detecting means detects a predetermined room temperature within the fixed period.

[0006]

【Example】

 An embodiment of the present invention will be described below with reference to FIGS.

In each drawing, 1 is a thermistor as a temperature detecting means for detecting room temperature and outputting room temperature information, 2 is a microcomputer as a control means, 3 is a kerosene burner, a gas burner or a burner for generating warm air. A heating element such as an electric heater.

In this configuration, the microcomputer 2 that drives the heating element 3 performs the heating operation only once at the beginning of the operation and only when the room temperature detected by the thermistor 1 is equal to or lower than a predetermined value. Only when the thermistor 1 detects a predetermined room temperature within a certain period of time from the start, or until the thermistor 1 detects a predetermined room temperature, the heating element 3 is controlled to operate with a special maximum output that is larger than the maximum output during the steady state. I am trying.

Specifically, as shown in the flow chart of FIG. 1, if the room temperature detected by the thermistor 1 at the beginning of the heating operation is 5 ° C., which is a predetermined value or less, such as 10 ° C., If the thermistor 1 detects a room temperature of 10 ° C for a fixed time, for example, 15 minutes from the start, until that time, the heating element 3 has a special maximum output that is larger than the maximum output during the steady state, for example, If the steady output of the heating element is 3,200 kcal / h, 10% increase to 3,500 kcal / h, which is a high output that is not suitable for unlimited continuous operation due to the life of the heating element. The operation of the heating element 3 is controlled only once when the operation is started.

Since the configuration of the embodiment is as described above, the temperature rise rate of the room temperature is accelerated, and accordingly, the temperature rise of the load of the floor, walls, windows, etc. of the room is also relatively accelerated, and the comfort of heating is realized. I was able to increase the effect.

[0011]

[Effect of device]

 As described above, according to the present invention, it was possible to realize a warm air heater that quickly realizes comfortable heating.
