DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, a hot water temperature setting device for a hot water supply apparatus according to the present invention will be described with reference to an embodiment shown in the drawings. Reference numeral 1 is a main remote controller connected to a petroleum water heater (not shown) with a built-in bath by a lead wire, which is mounted on the wall of the kitchen or the like. 2 is a hot water supply switch that controls the start and stop of hot water supply,
An automatic bath switch 3 starts and stops the automatic bath operation.

Reference numeral 4 denotes hot water temperature setting means for setting the hot water supply temperature, which is a push type up switch 5 for raising the set temperature and a push type down switch 6 for lowering the set temperature.
Further, the up switch 5 also functions as a timepiece and the down switch 6 also functions as a minute setting switch of the timepiece.

Reference numeral 7 denotes a liquid crystal display section for displaying the operating condition and setting state of the water heater, and a hot water temperature display section 8 for digitally displaying the set temperature set by the hot water temperature setting means 4.
A bath temperature display unit 9 for digitally displaying the bath temperature set by a bathroom remote controller (not shown) attached to the bathroom, a clock display unit 10 for displaying the time, and the like are provided.

Reference numeral 11 denotes a pressing time determination unit which counts the pressing time of the hot water temperature setting means 4 and judges whether the pressing time is a predetermined time or more than 3 seconds, and whether the up switch 5 is pressed or the down switch 6 is pressed. Different signals are output based on the pressing determination and the determination as to whether or not the time is longer than a predetermined time.

Reference numeral 12 denotes a set temperature changing means for receiving a signal from the pressing time determination section 11 to change the set temperature and displaying the changed state on the hot water temperature display section 8 when the pressed time is less than 3 seconds. Between 50 ° C and 50 ° C in 1 ° C increments, between 50 ° C and 60 ° C in 5 ° C increments, and between 60 ° C and 70 ° C in 10 ° C increments. When the switch 5 is pressed for 3 seconds or more, the temperature is set to 70 ° C. which is the maximum temperature when the up switch 5 is used, and 40 ° C. which is the initial value of the remote controller 1 when the down switch 6 is used. Similarly, the temperature is set directly, and the temperature cannot be set midway.

The pressing time determining section 11 and the set temperature changing means 12 are composed of a single microcomputer 13, and the microcomputer 13 has other calculation, storage and comparison functions.

Next, the operation of the embodiment of the present invention will be described with reference to the flowcharts shown in FIGS. Now press the up switch 5 to change the set temperature (step 1
4) The pressing time determination unit 11 determines whether or not the pressing time is 3 seconds or more (step 15). If the pressing time is less than 3 seconds, the process proceeds to step 16 with NO, and the set temperature is increased by one. Therefore, the pressing temperature of less than 3 seconds is intermittently changed to sequentially change the set temperature to the high temperature side for each set step and display the set temperature on the hot water temperature display section 8.

On the other hand, if the key is pressed for 3 seconds or more, the process proceeds to step 17 with YES, the preset temperature is set to 70 ° C. directly without the intermediate temperature, and this is displayed on the hot water temperature display section 8.

When the down switch 6 is pressed (step 18), it is determined in step 19 whether or not the pressing time is 3 seconds or more, and if the pressing time is less than 3 seconds, NO is returned to step 20. The set temperature is changed to a temperature one level lower than the set temperature. Therefore, by intermittently pressing the set temperature for less than 3 seconds, the set temperature is sequentially changed to the low temperature side at every set step and displayed. It is a thing.

If the pressure is further applied for 3 seconds or longer, the process proceeds to step 21 with YES, and the set temperature is directly set to 40 ° C. without any intermediate temperature, and this is displayed.

Therefore, if the desired temperature is a direct set temperature, the set temperature can be changed in a minimum of 3 seconds, and the set temperature can be changed by reheating the bath while hot water is being supplied, as in the case of the one-can-two-channel method. It is suitable for those that require frequent setting changes between high temperature and low temperature.

When it is desired to set the temperature in the vicinity of the direct setting, the desired temperature can be set by the intermittent pressing of the up / down switches 5 and 6 for less than 3 seconds after the direct setting, which is faster than the setting by the intermittent pressing from the beginning. It is easily set.

In this embodiment, the direct set temperature is set to 70 ° C., which is the maximum temperature required on the hot water supply side when hot and hot water is simultaneously used by the one-can-two-channel method on the high temperature side, and the low temperature side is the initial of the remote controller 1. I made it easier to use the value of 40 ℃,
Without being limited to this, for example, it may be set while listening to the wishes of the user at the time of installing the device, or the user may freely change it to further improve the convenience of use. The learning function or the like may be used to automatically set the temperature to a frequently used temperature.

[0019]

In summary, the present invention has a hot water temperature setting means 4 for setting a desired hot water temperature, and a hot water temperature display section 8 for digitally displaying the hot water temperature set by the operation of the hot water temperature setting means 4.
In the pressing time determination unit 11 that determines whether or not the pressing time of the hot water temperature setting unit 4 is equal to or longer than a preset predetermined time, and the pressing time determination unit 11 detects the pressing time of the hot water temperature setting unit 4 that is shorter than the predetermined time. Since the set temperature is changed one by one for each press, and the set temperature changing means 12 is provided for directly changing the set temperature to a predetermined temperature set in advance in the press detection for a predetermined time or more, The desired temperature can be set easily and surely, and the setting time is short, resulting in excellent operability.
