Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a hot water cleaning device.

[0002]

2. Description of the Related Art Conventionally, in a warm water washing apparatus having a control device for controlling the load, that is, the operation of a heater, a pump, a fan, etc., based on a detection signal from a human body detecting means such as a seating switch, the seating switch detects the human body sitting. Only when this was done, a structure was adopted in which spouting of wash water for hot water washing operation and warm air blowing for drying were started and continued.

[0003]

By the way, a hot water temperature setting switch for setting the temperature of the washing water sprayed on the portion to be washed by the user, a toilet seat temperature setting switch for setting the temperature of the toilet seat, etc. are also used when the human body is detected. Because of the operable structure, the user can arbitrarily set the hot water temperature and the toilet seat temperature. If such a device is installed in a place such as a building where many unspecified users use it, for example, if a user changes the hot water to a higher temperature, the higher temperature setting will remain. Since the heat retention control is performed, extra energy for heat retention is required, and the running cost for using the warm water flush toilet seat is additionally consumed. For this reason, building owners and the like who are highly conscious of costs have caused maintenance personnel to periodically return the set temperature to the standard in order to eliminate this waste.

As described above, when the device user and the device owner are different, running costs are not taken into consideration, and energy is wasted. It is conceivable to eliminate the temperature setting switch in order to solve this, but the setting switch cannot be eliminated for the following reasons. The set temperature itself varies due to variations in products (thermistors) whose sensible temperature changes depending on the season or the outside temperature.

[0005]

[Means for Solving the Problems, Functions and Effects] The technical means taken in the invention of claim 1 for solving the above-mentioned technical problems is a cleaning device for injecting cleaning water to a portion to be cleaned of a user. A cleaning water temperature control means for controlling the temperature of the cleaning water, a toilet seat temperature control means for controlling the temperature of the toilet seat, the cleaning device, the cleaning water temperature control means, and the toilet seat temperature control means, respectively. In a hot water cleaning device including operating means for operating, the cleaning water temperature control means, a first mode in which the set temperature of the toilet seat temperature control means can be changed, and a change in the set temperature that is disabled Since it is equipped with a change-over switch for switching between the two modes, when the device user and the device owner are installed in different places such as a department store or a building, the hot water temperature and the toilet seat temperature can be Setting By that to obscure the,
Energy can be saved because the temperature is not changed abruptly.

Further, in the invention of claim 2, in addition to the invention of claim 1, the changeover switch, the switch for setting the temperature of the toilet seat, and the switch for setting the temperature of the wash water are covered with an openable / closable cover. It is possible to further prevent operations from an unspecified number of people.

Further, in the invention of claim 3, in addition to the invention of claim 1 or 2, if the changeover switch is not continuously pressed for a predetermined time or more, the second mode is changed to the first mode.
Since the switch to the mode is not executed, even if the presence of the switch is known to an unspecified number of people, it cannot be operated because it is not accepted by normal operation, and the set temperature may be changed unexpectedly. There is no.

Further, in the invention of claim 4, in addition to the invention of claim 3, since the state of the first mode is switched to the second mode after a predetermined time has elapsed, the maintenance person changes the set temperature. Even if it is left in the possible first mode, it switches to the second mode within a predetermined time, so that the set temperature is not abruptly changed.

According to the invention of claim 5, in addition to the invention of claim 2, the switch for setting the temperature of the toilet seat, the switch for setting the temperature of the wash water, and the peripheral portion where both switches are arranged are dim single color. Therefore, even if the mode can be changed by the setting mode on / off switch, it is possible to reduce the possibility that the set temperature is changed because the temperature change switch is difficult to see.
