DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heater for switching between floor heating and hot air heating.

[0002]

2. Description of the Related Art Conventionally, in a heater of this type, a water filling switch is provided in an operation device thereof. When the water filling switch is pressed, a circulation pump is operated to fill the floor with water for floor heating. .

[0003]

However, in this case, since a water-filled switch is indispensable, there is a disadvantage that the layout of the operation device is limited.

[0004] In view of the above circumstances, an object of the present invention is to provide a heater capable of omitting a water filling switch and preventing breakage of a circulation pump due to idling.

[0005]

That is, the present invention provides an operation switch (2), a floor temperature control switch (3) comprising an up switch (3a) and a down switch (3b), floor heating and hot air heating. Operation switch (1)
9) and a circulation pump (22), and a heater (23) in which water is filled by operation of the circulation pump.
In the above, when a switch different from an operation switch such as the floor temperature adjustment switch is pressed in a state where the operation changeover switch is set to floor heating and the operation switch is turned off, the circulation is performed. After the pump is operated for a certain time to perform water filling, a circulating pump control means (20, 21) for stopping the circulating pump is provided.

[0006]

According to the above construction, the present invention works so that the existing floor temperature control switch (3) and the like also function as a water filling switch.

[0007]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a front view showing an example of a heater operating device according to the present invention, FIG. 2 is a control block diagram showing an embodiment of a heater according to the present invention, FIG. 3 is a flowchart showing an example of a water filling program, FIG. 4 is a piping diagram showing a specific usage example of the heater.

As shown in FIG. 2, the heater 23 according to the present invention has a microcomputer 20 having a built-in ON timer 21 for a fixed time, and a circulation pump 22 and the like are connected to the output side of the microcomputer 20. I have. An operation device 1 is connected to an input side of the microcomputer 20, and the operation device 1 includes an operation switch 2, a floor temperature adjustment switch 3, a time changeover switch 6, a digital display unit 7, as shown in FIG. 9. Plus switch 10 and minus switch 1 for time adjustment
1, an up switch 12 and a down switch 13 for adjusting the room temperature, a minute switch 15, a minute lamp 16, an inspection lamp 17, an operation changeover switch 19, and the like.

[0010] Since the heater 23 according to the present invention has the above-described configuration, when floor heating is performed using the heater 23, water is first filled based on the water filling program PRG as shown in FIG. Perform

That is, first, in step S1 of the water filling program PRG, it is determined whether or not the operation switch 19 is set to "floor warm" or "stove + floor warm". If it is determined that the condition is not "stove + floor warming" (that is, "stove"), it is not necessary to perform water filling, so the process enters step S5 of the water filling program PRG and stops the circulation pump 22. Leave it alone. On the other hand, when it is determined that the operation changeover switch 19 is set to “floor warm” or “stove + floor warm”, the process proceeds to step S2 of the water filling program PRG, and determines whether the operation switch 2 is turned off. Is determined.

As a result, if it is determined that the operation switch 2 has not been turned off (that is, it has been turned on), it is considered that the water filling has already been completed. And the circulation pump 22 is kept stopped. On the other hand, when it is determined that the operation switch 2 is turned off, the process proceeds to step S3 of the water filling program PRG, and whether or not the floor temperature control switch 3 is double-pressed (that is, the floor temperature control switch 3 It is determined whether or not the up switch 3a and the down switch 3b are pressed simultaneously.

As a result, when it is determined that the floor temperature control switch 3 is not double-pressed, the water filling program P
In step S5 of RG, the circulation pump 22 is kept stopped. However, when it is determined that the floor temperature control switch 3 is double-pressed, step S4 of the water filling program PRG is entered and the ON timer 21 After operating the circulation pump 22 for a certain period of time to perform water filling,
In step S5 of the water filling program PRG, the circulating pump 22 is stopped so that the circulating pump 22 is not broken.

That is, as shown in FIG. 4, when it is determined that the pressing operation is the double pressing, the heater 23 operates the circulating pump 22 for a certain period of time without operating the burner b, and the hot water tank c
(Or hot water) is flowed through the floor heating panel d and the heat exchanger e to fill the floor with water.

[0015]

As described above, according to the present invention,
An operation switch 2, a floor temperature adjustment switch 3 including an up switch 3a and a down switch 3b, an operation changeover switch 19 for switching between floor heating and hot air heating, and a circulation pump 22 are provided. In the heater 23 that is to be performed, the operation changeover switch 19 is set to the floor heating mode, and the operation switch 2 is turned off. When the switch is pressed, the circulating pump 22 is operated only for a certain period of time to perform water filling, and then a microcomputer 20 for stopping the circulating pump 22 and a circulating pump control means such as an ON timer 21 for a certain period are provided. Since the existing floor temperature control switch 3 and the like also function as a water-filled switch, the water-filled switch Together may be abbreviated, heater 23 can be prevented even damage to the circulation pump 22 by idling
Can be provided.

Claims (1)

(57) [Claims] An operation switch, a floor temperature adjustment switch comprising an up switch and a down switch, an operation changeover switch for switching between floor heating and hot air heating, and a circulation pump, wherein water is filled by operation of the circulation pump. In the heating machine, while the operation changeover switch is set to the floor heating and the operation switch is turned off, another switch different from the operation switch such as the floor temperature adjustment switch is pressed. In this case, a circulating pump control means for stopping the circulating pump after operating the circulating pump for a predetermined time to perform water filling is provided.
