JPS63701A - Setting device for control target value - Google Patents

Abstract

PURPOSE:To avoid such a case where the undesired control target value is inadvertently set and to ensure the safe use of a shower, for example, by limiting an effective set value area of the repeating function to a range that is usually used. CONSTITUTION:A control target value setting device consists of an Up switch 1 and a Down switch 2 which increase and decrease the set value respectively, and a control value setting circuit 3 which can change the set value with operations of both switched 1 and 2. The circuit 3 has a repeating function to repeat the sequential increase or decrease of the set value in a prescribed set value area during operation of the switch. While the control value is set in other areas by a step action where the set value is increased or decreased in response to the operating frequency of the switch. Thus it is possible to avoid such a case the hot water or cool water splashes even for a short time while the set temperature is corrected.

Description

DETAILED DESCRIPTION OF THE INVENTION (Technical Field) The present invention relates to a control target value setting device used for controlling temperature, volume, light intensity, flow 1, etc.

(Conventional technology C) For example, when setting the hot water temperature in a conventional water heater, the control value can be set completely freely with the same operation over the entire controllable area, so if the temperature is set carelessly, the hot water It had the disadvantage of having to be bathed in cold water.

For example, If 'J! , when trying to set the hot water temperature using a temperature setting circuit with a repeat function via an up/down switch as in Publication No. 59-42603, if the response of the switch is fast, the set humidity may exceed the desired temperature. You may not be able to quickly set the desired temperature - 1 because the temperature may go back too much or return too much. At this time, the appliance is controlled to the wrong (undesired) set temperature, so
The drawback was that while adjusting the temperature setting, users were exposed to hot or cold water for a short period of time.

Also, if the response of the switch is slow, it is difficult to use.

(Object of the Invention) The present invention has been made in consideration of the above-mentioned circumstances, and it is possible to control areas that are not generally used due to safety, comfort, etc., among controllable areas. $1 that prevented the target value from being set! The objective is to provide an arsenic target value setting device.

(P! J r'& of the invention) In order to achieve the above-mentioned purpose, the present invention provides a power switch for increasing the set value, a down switch for decreasing the set value, and a down switch for reducing the set value. In a control target value setting device having a control value setting circuit that can change and set a set value by operating a switch, the control value setting circuit comprises:
In a predetermined set value region, the set value has a repeat function in which the set value is sequentially increased or decreased while the switch is operated, and in other set value regions, the set value is increased or decreased in accordance with the number of times the switch is operated. The control value is configured to be set by step operation.

(Removal of implementation) Hereinafter, the present invention will be specifically explained based on illustrated examples.

In the figure, (1) is an up switch, (2) is a down switch, and (3) is a control value setting circuit. This control #
The value setting circuit (3) can set the preset temperature of the shower (not shown) between 18°C and 48°C, and between 38°C and 42°C.
．． It has a repeat function in the range of 5°C, and it has a repeat function in the range of 18°C to 3°C.
In the range of 8°C, step operation of 2°C per operation of down switch [2], and 42.5°c-48
°C [0 for each operation of up switch (1)
．． How the set temperature is changed by step operation of 5°C will be explained based on FIG. 2.

When the system is powered on, the set temperature shows the default value of 41°C. For example, when changing the set temperature from 40°C to 46°C, press the up switch (1)'1flt to raise the set temperature. 4°00 to 42.5°C
In the range of , there is a repeat q function, so the up switch (1
) can be held down. Set temperature is 42.5°C
When the control value setting circuit (3) reaches this point, the control value setting circuit (3) loses its repeat function, and even if the button is kept pressed, the set temperature will not change. After the set value reaches 42.5°C, the set temperature is increased step by step by repeatedly pressing the amplifier switch (1). That is, each time the up switch (1) is pressed, the set temperature increases by 0.58C, and the desired set temperature rises by 0.58C.
Repeat the operation of the up switch (1) (7 times in this case) until the temperature reaches 6°C. Also, for example, from 46°C to 20°C
To change the set temperature to 'O', press the down switch (
2) If you continue to use the setting temperature, the repeat function will change the set temperature to 4.
The temperature continues to drop from 6°C to 38°C, which is the lower limit of the repeat function.
When the set temperature reaches °C, the repeat function of the control value setting circuit (3) is lost and the set temperature no longer changes. 38°
When further lowering the set temperature from C, the set temperature is lowered step by step by repeatedly pressing the down switch (2). In other words, each time the down switch (2) is pressed, the set temperature decreases by 2°C, and the desired set temperature is lowered by 2°C.
Press down switch (2) repeatedly as required (9 times in this case) until the temperature reaches 0°C.

(Effects of the Invention) As described above, according to the present invention, in a control target value setting device having an amplifier switch, a down switch, and a repeat function, the repeat function is effective for setting. Since the value range is limited to a range of functions that can only be used on a one-time basis, there is no risk of inadvertently setting control target values that are not used for boat fishing. Can be used. Incidentally, the control target values used in special cases can also be easily set by repeatedly operating these switches.
