Abstract

PURPOSE:To surely confirm the designation of the kind of device by providing a decision section deciding the applied device kind based on an input signal from a device kind designation switch section into a microcomputer and a display section displaying the result of decision to an operating device. CONSTITUTION:An input switch for temperature setting value or the like for a hot water supply device and a controller 3 provided with a display device displaying whether or not the operation of the hot water supply device is normal are connected to a main body control circuit A and a display section 4 used in common for the display of a reserved time and the device kind display is provided to the operating device 3. After a remote control check terminal 5 is connected to ground, the operating device 3 is connected to the main body control circuit A and power supply is applied, then the checking mode is started and a decision section in the microcomputer 1 discriminates to which kind of device the jumper connection of a device kind-designation switch section 2 corresponds and the device kind is displayed on the display section 4 according to the result of the decision. Thus, a checker can decide whether or not the connection state of jumpers 2a, 2b... is correct and lookover of the connection or mis-discrimination is avoided.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a remote control device applied to, for example, a water heater, and in particular, to more reliably implement model designation that is set corresponding to the model. This relates to remote control devices for water heaters, etc.

(Prior Art) Conventionally, for example, remote control devices for water heaters include operating devices designed to be compatible with a plurality of models, as shown in Japanese Patent Application No. 63-121344.

In this type of remote control device, a microcomputer (hereinafter referred to as microcomputer) is configured to selectively process control sequences for multiple models, and in order to select this control sequence, a jumper-connected resistor circuit, etc. is connected to the microcomputer. The configured model specification switch section is connected. Whether or not this jumper connection is correct is dependent on visual inspection.

(Problem to be Solved by the Invention) However, when inspecting the connection of jumper wires by visual inspection, errors or oversights may occur, and there is a problem with the reliability of the inspection.

The present invention has been made in consideration of the above circumstances,
The purpose of this is to enable more reliable confirmation of model designation.

(Means for Solving the Problems) As shown in FIG. 1, for example, the present invention includes a microcomputer 1 that is capable of controlling multiple models in a main body control circuit, and a model designation signal corresponding to the applicable model is input to the microcomputer 1. In a remote control device such as a water heater, which is equipped with a model designation switch section 2 for controlling a water heater, and an operating device 3 connected to the main body control circuit,
In order to achieve the above objectives, we have taken the following measures:

That is, the microcomputer 1 is provided with a determination section that determines the applicable model based on the input signal from the model designation switch section 2, and a display section 4 that displays the determination result on the operation device R3.
will be established.

(Function) In the present invention, the microcomputer 1
A signal corresponding to the connection state is inputted, and the model corresponding to the connection state is determined and displayed on the display unit 4. Therefore, it is possible to check whether the model designation switch section 2 is suitable or not based on this display content.

(Example) Hereinafter, the present invention will be specifically explained based on rotation.

FIG. 1 is a block circuit diagram showing the configuration of a remote control device for a water heater or the like according to an embodiment of the present invention.

In the figure, A indicates a main body control circuit connected to a commercial power source in the water heater main body, and this main body control circuit A includes a microcomputer 1 configured to selectively process control sequences of a plurality of models; The microcomputer 1 is provided with a model designation switch section 2 consisting of a jumper-connected resistor circuit that provides a voltage signal corresponding to the selected model.

The microcomputer 1 is provided with a determination unit that determines the applicable model based on the input signal from the model designation switch unit 2,
In this determination section, for example, a determination operation as shown in FIG. 2 is executed.

That is, after starting the test mode (Sl), a signal is input from the model designation switch section 2 (S2), and selections are made in order such as whether or not model 1 is selected (S3), and whether model 2 is selected (S3). The determined model is displayed on the display unit 4 of the operating device 3 with a numerical code representing the model, such as 01 representing model 1 and 02′ representing model 2. Display (S5), (S
6) It is configured as follows.

The model designation switch section 2 includes a jumper wire 2a for grounding any one of the plurality of input ports of the microcomputer 1;
2b, . . . and resistors Ra, Rb, . . . that set the voltage applied to each input port.

Connected to the main body control circuit A is an operating device 3 equipped with an input switch for setting the temperature of the water heater, etc., and a display device for displaying whether the water heater is operating normally or not. A display section 4 is provided which serves both to display the reservation time and to display the model.

Incidentally, the microcomputer 1 is provided with a remote control check terminal 5.

In the above configuration, the check mode is started when the remote control check terminal 5 is grounded, the operating device 3 is connected to the main body control circuit A, and the power is turned on. It is sufficient to connect the jumper wires 2a, 2b, etc. before the test mode starts during the check mode, but in order to prevent abnormal input from being made to the microcomputer 1 due to short circuits etc. during the connection work. It is preferable to complete the connection of the jumper wire 2 before turning on the power.

Then, the determination unit in the microcomputer 1 determines which model the jumper connection corresponds to, and according to the determination result, the display unit 4 displays, for example, O1″ for model l, O1″ for model 2,
In the case of , the model is displayed as 02'. The inspector can judge from this display whether the connection status of the jumper wires 2a, 2b, ... is correct or not, and can avoid overlooking or misreading the connections of the jumper wires 2a, 2b, ... .

In the above embodiment, the display section 4 is used both to display the reservation time and to display the model type, but there is no problem in providing the display section 4 as a display section exclusively for displaying the model type.

〔Effect of the invention〕

As described above, according to the present invention, the inspector can check the connection status of the jumper wires by checking the display contents on the display unit, and the inspector can confirm the connection status of the jumper wires by checking the display contents on the display unit. There is no risk of oversight or misunderstanding, and more reliable inspections can be carried out.
