Abstract

PURPOSE:To keep a comfortable temperature and humidity state by a method wherein a detected humidity in a hot air heating device having a humidifying device and a hot air feeding device is compared with predetermined first to third reference humidities and an operation of the humidifying device is controlled in response to a presence or a non-presence of an operation of the hot air feeding device. CONSTITUTION:A control circuit 8 for a hot air feeding device A may read an output from a temperature sensing sensor 14. If the output is less than the first predetermined temperature (for example, 18 deg.C), the hot air feeding device A is operated and if the output is more than the second predetermined temperature (for example, 24 deg.C), the hot air feeding device is stopped. Then, a control circuit 17 for a humidifying device B may read an output of a humidity sensing sensor 21 and if the output is less than the first predetermined humidity (for example, 40%), the humidifying device B may start its operation and if the output is more than the second predetermined humidity (for example, 60%), the operation of the hot air feeding device is stopped. In addition, if a room temperature is less than 18 deg.C and a humidity is in a range of 40 to 60%, the hot air feeding device A may start its operation and the humidifying device B is stopped. If the room temperature is increased, a humidity is relatively lowered and a detected humidity is less than the third predetermined humidity (for example, 55%), the humidifying device B is operated to keep s humidity of about 40 to 60%.

Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a hot air heating device having a humidifying unit 7 and a hot air unit.

(B) Conventional technology Conventionally, this kind of hot air heating device had an ultrasonic humidifying unit and a hot air unit.
It is known from Publication No. 0 (F24F 1100).

This device detects the ambient humidity and controls the humidifying unit so that the detected humidity falls within a preset humidity range.

However, if the indoor humidity is within the preset humidity range and the humidifier unit is stopped and the hot air unit is activated, the humidity will relatively decrease due to the rise in room temperature and will fall outside the preset humidity range. Although the humidifying unit works, it takes a long time to reach the set humidity range, which causes discomfort to the user.

(c) Problems to be Solved by the Invention The present invention has been made in view of the above-mentioned drawbacks, and an object thereof is to provide a hot air heating device that does not cause discomfort to the user.

(d) Means for solving the problem Detect the ambient humidity, compare the detected humidity with preset first reference humidity, second reference humidity, and third reference humidity, and if the detected humidity is the first reference humidity. Activating the humidifying unit when the humidity is below a reference humidity, stopping the humidifying unit when the humidity is above a second reference humidity, and activating the humidifying unit when the detected humidity is below a third reference humidity when the warm air unit is in operation. It is characterized by being equipped with a humidity control means.

(e) Operation If the room temperature is below the first setting temperature and the humidity is above the first setting humidity and below the second setting humidity, the hot air unit starts operating, but the humidifying unit stops operating. When the warm air unit starts operating, the room temperature rises and the humidity decreases relatively, and when the detected humidity falls below the third set humidity, the humidifying unit is activated to maintain a comfortable level of humidity above the first set humidity and below the second set humidity. Maintain proper humidity conditions.

(f) Example An embodiment of the present invention will be described in detail below based on the drawings.

In Fig. 3, ■ is a main body made of synthetic resin (oil), and has an intake port [1 (not shown)] on the back and an exhaust port 2 on the front. The heated air is heated and exhausted through an exhaust port 2. Further, a humidifying unit B consisting of an ultrasonic vibrator, a blower, etc. is provided at the upper part of the main body 1. A switch panel mounted on the top of the unit 1 is provided with switches for controlling the hot air unit A and the humidifying unit B.

FIG. 2 shows a circuit diagram in which a hot air unit l-A and a humidifying unit l-B are connected to a power source 4 in parallel.

The warm air unit A has a heater 5.6 and a blower motor 7, and the heater 5.6 and the blower motor 7 are controlled to open and close by a signal from a control circuit 8.
10.11, the energization is controlled.

The control circuit 8 controls the heater of the switch panel 3 by switching the selector switch 13, which is switched by operating a selection switch provided on the switch panel 3 of the main body 1, to a first contact 13a and a second contact 13b. There is a manual mode in which the user operates a switch to control the power supply to the heater 5.6, and the room temperature is maintained within a preset temperature range by the output of the temperature detection sensor 14 that detects the temperature around the main body 1. The automatic mode for controlling the heater 5.6 is selected.

The humidifying unit B includes a power unit H5 of an ultrasonic transducer.
The power supply unit 15 and the blower motor 16 are energized by switches 18 and 19 whose opening and closing are controlled by signals from a control circuit 17.

The control circuit 17 switches the selector switch 20, which is switched in conjunction with the selector switch 13, between the first contact 20a and the second contact 20b by operating a selection switch provided on the switch panel 3 of the main body 1. , a manual mode in which the user operates the humidification amount control switch on the switch panel 3 to control the power supply to the power supply unit 15, and a manual mode in which the indoor humidity is set in advance by the output of the humidity detection sensor 21 that detects the humidity around the main body 1. The power supply unit 7 15 maintains the humidity within the specified humidity range.
Automatic mode to control the selection.

When the manual mode is selected, the warm air unit 1-A and the humidifying unit B are controlled by the user appropriately selecting and operating the heater control switch and humidification amount control switch provided on the switch panel 3 of the main body 1. is controlled to heat and humidify the room regardless of the outputs of the temperature detection sensor 14 and humidity detection sensor 21.

Next, the automatic mode selection will be explained based on the flowchart shown in FIG. In the example, it is determined whether the temperature is 18°C or higher. If the detected temperature is below the first set temperature in S2, switch 9.
1o and 11 are closed, and the heater 5.6 and blower motor 7 are closed.
Turn on the power to operate the hot air unit/to A.

If the detected temperature is equal to or higher than the first set temperature in S2, S

℃) or above is judged. In S4, the detected temperature is the second
If the temperature is higher than the set temperature, the hot air unit A is stopped in S5.

When the automatic mode is selected, if the room temperature is below the first set temperature (18°C), the hot air unit A starts operating in S3, and the room temperature rises to above the second set temperature (24°C). If so, the operation is stopped in S5 to maintain the room temperature in a comfortable state.

Next, in S6, the control circuit 16 controls the humidity detection sensor 2.
1 is read, and in S7 it is determined whether the detected humidity is equal to or higher than a first preset humidity (40% in this embodiment). If the detected humidity is equal to or lower than the first set humidity in S7, the switches 18 and 19 are closed in S8, and the power supply unit 15 and the blower motor 16 are energized to operate the humidifying unit B.

If the detected humidity is equal to or higher than the first set humidity in S7, S

In S9, whether the detected humidity is greater than or equal to the third set humidity;
Or, even if the detected humidity is lower than the third set humidity, 510
If the hot air unit 7A is stopped at step 512, it is determined whether the detected humidity is higher than the second set humidity (60% in this embodiment), and if it is higher than the second set humidity, the detected humidity is set at 512.
At step 13, the humidifying unit B is stopped.
