Abstract

PROBLEM TO BE SOLVED: To ensure comfortable heating using a heating apparatus and a circulator. SOLUTION: When heating operation interlocked with a circulator is started, sensed temperature T1 of a warm air heating apparatus is read to judge whether or not the sensed temperature T1 exceeds temperature T0 (steps 100,102). Further, sensed temperature T2 of the circulator is read to judge whether or not a temperature difference >=T exceeds a temperature difference TS(steps 104 to 108). Hereby, once the sensed temperature T1 exceeds the temperature T0 or once the temperature difference >=T exceeds the temperature difference TS, the circulator is operated (step 110), and once the sensed temperature T1 and the temperature difference >=T are lowered, the circulator is interrupted (step 112).

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heating system in which a heating device such as a hot air heating device and a circulator for circulating air in the room are provided in the same room.

[0002]

2. Description of the Related Art In order to heat a room, a fuel such as gas or oil is burned in a combustion chamber in addition to an air conditioner.
There is a hot air heating device that heats air sent by a blower fan to generate warm air, and blows the warm air from an outlet to heat the room. This hot air heater is
It is placed on the floor in a room and is used to heat the floor from the floor with warm air.

In a room to be heated, the room temperature near the floor is low and the room temperature near the ceiling is high. For this reason, a circulator may be provided near the ceiling, and the indoor air may be circulated by the circulator to eliminate a temperature difference and to provide a comfortable heating state in the room.

[0004]

However, since the circulator is operated separately from the hot-air heating device, it is difficult to obtain a feeling of heating or the air is blown out from the circulator despite heating. The air may cause a feeling of cool wind. For example, when the air volume of the warm air heating device is small, the warm air heating device side may not be able to obtain a feeling of heating when the warm air heating device is separated from the warm air heating device even though the room temperature is high. When the circulator is operated in such a state, the air blown out from the circulator may cause a feeling of cool wind.

The present invention has been made in view of the above-mentioned circumstances, and has as its object to propose a heating device such as a hot air heating device and a heating system that can make a room in a comfortable heating state using a circulator. And

[0006]

In order to achieve the above object, the present invention provides a heating device for heating a room, a circulator for circulating the air in the room, and a circulator for interlocking the heating device with the heating device. Interlocking control means for operating a circulator in accordance with a heating state of the device.

According to the present invention, the heating device and the circulator are electrically connected, and the circulator is operated according to the heating state of the heating device. By operating the circulator in accordance with the heating state, temperature irregularity is caused because the circulator is not operated, and it is possible to prevent the temperature irregularity from causing discomfort. The feeling can be prevented from being generated.

[0008] In the present invention, the heating device is a hot air heating device provided near the floor of the room for heating by blowing out hot air generated by burning fuel for heating.
It is preferable that the circulator is provided near the ceiling in the room, and a great effect is obtained.

The invention according to a third aspect is a first aspect of the present invention, wherein the heating apparatus detects a room temperature on the heating apparatus side.
Detecting means provided in the circulator, a second detecting means for detecting the indoor temperature on the circulator side,
Wherein the interlocking control means operates the circulator based on the first and second temperature detection results.

According to the present invention, each of the heating device and the circulator is provided with detecting means for detecting the temperature, and the circulator is operated based on the detection result of the detecting means.

The present invention is characterized in that the circulator is operated when the temperature detected by the first detecting means reaches a predetermined temperature.

For example, when the temperature around the heating device reaches a predetermined temperature, the temperature around the circulator is higher than this temperature. Therefore, if the surroundings of the heating device are in a predetermined heating state, even when the circulator is operated, the room can be uniformly heated without generating a feeling of cool air.

Further, the present invention is characterized in that the circulator is operated when a temperature difference between a temperature detected by the first detecting means and a temperature detected by the second detecting means exceeds a predetermined value.

According to this, when the temperature difference between the heating device and the circulator is large, the temperature unevenness in the room is large, so that the circulator is operated to make the temperature substantially uniform. Thereby, a comfortable heating state can be achieved without causing discomfort due to temperature unevenness.

[0015]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 schematically shows a heated room 42 provided with a heating system 40 formed by a warm air heating device 10 as an example of a heating device and a circulator 32 that circulates indoor air.

As a result, when the fan motor 24 drives the blower fan 22 to rotate, the room air is sucked into the casing 12 through the suction port 26. The air sucked at this time passes through the filter 28, thereby removing dust and dust floating in the air. The air sucked into the casing 12 is heated by passing near the combustion chamber 16, and is heated as warm air from the outlet 18 through the heated chamber 42.
(See FIG. 1).

In the casing 12, a combustion chamber 16 is provided.
A combustion shelter 30 is provided so as to cover the upper portion of the combustion chamber 16, thereby efficiently heating the air passing around the combustion chamber 16 and preventing the casing 12 from being overheated by the heat of the combustion chamber 16. .

As shown in FIG. 1, the circulator 32
Is provided within a casing 34 with a blower fan 36 using, for example, a cross flow fan or the like.

At this time, depending on the rotation direction of the blower fan 36, the air sucked from the grill on the lower side is blown out from the grill on the front side (both not shown), and the air sucked from the grill on the front side is blown out from the grill on the lower side. You can do it. In addition, the hot air heating device 1
A conventionally known general configuration can be applied to the circulator 0 and the circulator 32, and a detailed description is omitted.

As shown in FIG. 3, the hot air heating apparatus 10 is provided with a controller 44 having a microcomputer (not shown) as a control unit. The controller 44 is connected to a switch panel 46 (not shown in FIG. 2) provided, for example, at an upper portion of the casing 12 on the front side of the apparatus, together with the burner 14 and the fan motor 24. The warm air heating device 10 includes a room 42 to be heated.
A temperature sensor 48 is provided as first detection means for detecting the temperature in the inside, and the temperature sensor 48 is connected to the controller 44.

The controller 44 includes a switch panel 46
Hot air is generated based on the heating conditions such as the combustion amount and the set temperature set by the above switch operation, and the inside of the heated room 42 is heated.

The circulator 32 has a controller 50 provided with a microcomputer (not shown).
The controller 50 includes a blower fan 36.
A temperature sensor 54 provided in the circulator 32 as a second detection means is connected together with a fan motor 38 for driving the motor and an operation switch 52 for setting operation / stop and air flow.

When the operation switch 52 is operated, the controller 50 drives the fan motor 38 to blow air and circulate the air in the room 12. By operating the operation switch 52, the blowing direction (whether front blowing or downward blowing) and the blowing amount (the number of rotations of the fan motor 38) can be changed.

The controller 50 includes a circulator 32
Is operated independently of the hot air heating device 10,
When the temperature detected by the temperature sensor 54 is a predetermined temperature (for example, 40 °
When the time reaches C), the fan motor 38 is operated to start blowing air. Thereby, the air near the ceiling is circulated, and the inside of the room to be heated 42 is set to a uniform room temperature.

The controller 44 of the hot air heating device 10 and the controller 50 of the circulator 32
They are connected by a communication line 56. Thereby, in the heating system 40, bidirectional communication such as serial communication between the hot air heating device 10 and the controllers 44 and 50 of the circulator 32 is possible.

In the heating system 40, the hot air heating device 10
The serial communication is performed between the controller 44 of the circulator 32 and the controller 50 of the circulator 32, whereby the circulator 32 is detected based on the detected temperatures of the room temperature sensor 48 provided in the hot air heater 10 and the room temperature sensor 54 provided in the circulator 32. Is operated by remote control.

The controller 44 includes the circulator 32
When the heating operation of the hot air heating apparatus 10 is started in a state where the controller 5 is set so as to interlock, the temperature is detected by the temperature sensor 48 and the controller 5 of the circulator 32 is controlled.
0 to the temperature sensor 54 provided in the circulator 32
Read the temperature detected by.

At this time, the controller 44 determines that the temperature T ₁ detected by the temperature sensor 48 is a predetermined temperature T ₀ (for example, 30 °).
When C is exceeded, the circulator 32 is turned on and the fan motor 38 is operated. Further, the controller 44 includes:
The temperature difference ΔT between the detected temperature T ₁ of the temperature sensor 48 and the detected temperature T ₂ of the temperature sensor 54 provided in the circulator 32.
(ΔT = T ₂ −T ₁ ), and when this temperature difference ΔT exceeds a preset temperature difference T _S (for example, 10 ° C.),
The circulator 32 is operated.

The operation of this embodiment will be described below.

In the hot air heating device 10, the switch panel 4
The heating conditions such as the set temperature and the amount of combustion are set by operating the switch 6 and the operation switch is turned on, so that the burner 14 starts burning fuel (kerosene). At this time, the combustion amount of the burner 14 (fuel supply amount) and the rotation speed of the blower fan 22 (the rotation speed of the fan motor 24)
Is set based on the combustion amount and the set temperature.

Thus, the air sucked by the blower fan 22 is heated when passing through the combustion chamber 16 heated by the burner 14, and is blown out from the outlet 18 as warm air.

On the other hand, when the operation switch 52 is operated, the temperature of the circulator 32 is detected by the temperature sensor 54, and when the detected temperature reaches a predetermined temperature, the circulator 32 operates the fan motor 38. Thereby, the circulator 32 makes the room temperature of the room to be heated 42 substantially uniform.

The heating system 4 in which the hot air heating device 10 and the circulator 32 are connected by a communication line 56
0, the circulator 32 is
Is controlling the operation.

Hereinafter, remote control of the circulator 32 will be described with reference to the flowchart shown in FIG. Note that this flowchart is executed when the heating operation by the hot air heating device 10 is started in a state in which the remote control operation of the circulator 32 by the hot air heating device 10 is set. ,
The process ends when the remote control operation of the circulator 32 is canceled.

When the heating operation by the warm air heating device 10 is started, the controller 44 provided in the warm air heating device 10 reads the detected temperature T ₁ detected by the temperature sensor 48 in the first step 100, 102
In this detected temperature T ₁ is, checks whether or not exceeded the predetermined temperature T _0.

[0038] In step 104, the detected temperature T ₂ detected by the temperature sensor 54 is not provided to the circulator 32, read by communicating with the controller 50, the detected temperature T ₁ of the detected temperature T ₂ The temperature difference ΔT is calculated (step 106). Thereafter, in step 108, it is confirmed whether or not the temperature difference ΔT has exceeded a predetermined temperature difference T _S.

Generally, when the hot air heating device 10 is operated, hot air is blown out along the floor surface. The air heated by the warm air gradually moves upward. The hot air blown from the hot air heating device 10 is heated by the hot air heating device 10.
The air flow gradually moves upward as the distance from the vehicle increases (see the broken line in FIG. 1).

As a result, in the heated room 42, the temperature near the ceiling farther from the floor surface becomes higher than that near the floor surface. That is, the temperature near the ceiling is higher than the temperature around the hot air heating device 10.

Therefore, as shown in FIG. 5A, the room temperature of the room 42 to be heated gradually increases from the floor surface toward the ceiling. Further, as the heating time becomes longer, the temperature difference becomes larger (the interval between the isotherms becomes narrower), which causes discomfort. 5A and 5B, the room 42
Is schematically shown by isotherms (1 ° C. intervals).

From this, in the flowchart shown in FIG. 4, the temperature T ₁ detected by the temperature sensor 48 of the warm air heater 10 installed on the floor reaches the predetermined temperature T ₀ , and an affirmative determination is made in step 102. If done, step 11
The operation proceeds to 0, and the circulator 32 is operated.

When the circulator 32 operates, the air near the ceiling is agitated, and the circulator 32 sucks and blows out the air below (indicated by a two-dot chain line in FIG. 1), so that convection flows into the room 12. Is caused. Thereby, as shown in FIG. 5B, the temperature difference between the air in the room 12 is reduced.

If the temperature T ₀ at this time is set to a high temperature that does not cause discomfort or cold when the air of this temperature is blown, the air near the circulator 32 will have this temperature T _0. Since it is higher, it is possible to provide a comfortable heating state without feeling a feeling of insufficient heating or cold.

On the other hand, when the indoor temperature difference ΔT increases,
This uneven temperature causes discomfort.

Here, in the flowchart shown in FIG.
If the temperature difference ΔT has reached the preset temperature difference T _S and the determination in step 108 is affirmative, the process proceeds to step 110 and the circulator 32 is operated. Thereby, the air in the room 42 to be heated is agitated by the air blown out from the circulator 32, thereby suppressing the temperature unevenness. The temperature unevenness generated when the warm air heating device 10 performs the heating operation causes discomfort. Can be prevented.

By operating the circulator 32 based on the temperature difference ΔT, the temperature in the vicinity of the floor is too low, even though the vicinity of the circulator 32 (near the ceiling) is too warm. It is possible to prevent a feeling of shortage and to make the room a comfortable heating state.

On the other hand, in the flowchart shown in FIG. 4, by operating the circulator 32 in this manner, the detected temperature T _1, which is the temperature near the floor, decreases,
In addition, when the temperature difference ΔT is reduced by eliminating the temperature unevenness in the room and the negative determination is made in step 102 and step 108, the process proceeds to step 112, and the operation of the circulator 32 is stopped.

As described above, in the hot air heating system 10,
The communication line 56 connects the hot air heating device 10 and the circulator 32 to each other.
To connect the circulator 32 to the hot air heating device 1
By performing the remote control operation with 0, when heating by the warm air heating device 10, a comfortable heating state can be achieved without causing discomfort due to uneven temperature or a feeling of insufficient heating. Further, the air blown out of the circulator 32 does not cause a feeling of cold or insufficient heating.

The present embodiment described above is an example of the present invention, and does not limit the configuration of the present invention. For example, in this embodiment, although so as to control the operation / stop of the circulator 32, based on the detected temperature T ₁ and the detection temperature T ₂ may be controlled to suit also blowing amount.

As the temperature T ₀ and the temperature difference T _S when the circulator 32 is operated, any temperature can be used as long as the operation of the circulator 32 does not cause a feeling of cool air.

Further, in the present embodiment, when operating the circulator 32 based on the temperature difference ΔT, the detected temperature T ₁ is not considered, but the detected temperature T ₁ is lower than the predetermined temperature T _0. In this state, the circulator 32 may be operated when the temperature difference ΔT becomes equal to or more than the temperature difference T _S , whereby the circulator 3
It is possible to more reliably prevent a feeling of cool wind from being generated by the air blown out from the second.

In the present embodiment, the hot air heating device 1
0 and the circulator 32 are connected by wire using the communication line 56, but may be connected wirelessly so that bidirectional communication is possible. Further, a remote control device may be provided separately from the hot air heating device 10 and the circulator 32, and the circulator 32 may be operated by the remote control device.

Although the present embodiment has been described using the hot air heating device 10 as the heating device, the heating device is not limited to this, and any conventionally known heating device can be used. The circulator 32 may have not only a function of circulating room air but also a function of stimulating indoor air and outside air.

[0055]

As described above, according to the present invention, the remote controller of the circulator is operated based on, for example, the temperature detected by the hot air heating device and the temperature detected by the circulator. Can be operated at appropriate timing, and an excellent effect that the interior can be kept in a comfortable heating state without temperature unevenness can be obtained.
