Abstract

PURPOSE:To prevent the elongation of a required time for heating up even when water is remaining in a bathtub by a method wherein the water in the bathtub is circulated and the temperature thereof is detected during pouring hot-water having a set temperature to start additional heating when the detected temperature is lower than the set temperature. CONSTITUTION:When an automatic operation switch 22 is put ON, a hot-water pouring valve 4 is opened and hot-water, heated by a tap-controlled water heater 1 to a temperature preset in a main remote controller 21, is poured into a bathtub 9 through a hopper 6. When a water level sensor 14 has detected that a water level in the bathtub 9 has become higher than the level of an upper circulating pipe 10, a circulation pump 16 is operated to circulate the poured hot-water together with the water in the bathtub 9 and detect the hot-water under circulation in the bathtub 9 by a temperature detecting sensor 15. When the temperature of hot-water in the bathtub is lower than a set temperature, a bath boiler starts additional heating. When the water level in the bathtub 9 has become a water level, preset in the main remote controller 21, the hot-water pouring valve 4 is closed and the hot-water temperature in the bathtub is decided whether it has arrived at the set temperature or not. When the temperature is lower than the preset temperature, additional heating is started. When the set temperature has been achieved, the additional heating is stopped and, thereafter, the operation of the circulation pump 16 is also stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to the automatic operation of an automatic hot water bath system.

Conventional technology Conventionally, this type of automatic hot water bath equipment has been used to supply hot water at a constant temperature from an instantaneous water heater to a set water level in the bathtub during automatic operation, and then heat the bathtub to a preset level using a hot water temperature setting device. That's what I was doing. (Patent Publication No. 10154/1983) Problems to be Solved by the Invention However, in the above operation, when water remains in the bathtub from the previous day which is lower than the set water level, water at a constant temperature is added to the bathtub. After boiling, the water is reheated to the set temperature, which poses a problem in that it takes a long time to boil the water.

Means to Solve the Problem In order to solve the above problem, hot water in the bathtub can be improved by circulating the hot water in the bathtub through the equipment using a pump while hot water at a set temperature is being poured into the bathtub from an instantaneous boiler. This system is equipped with a microcomputer that detects the temperature and starts reheating the bathtub when the temperature of the water in the bathtub is lower than the set temperature.

Therefore, in cases where residual water from the previous day remains in the bathtub at a level lower than the set water level, the temperature of the remaining water is lower than the set temperature, so start reheating, pour water up to the set water level, and then set the temperature again. Since reheating is performed until the temperature is reached, the amount of heat generated during reheating during raw frying can be reduced by the amount of heat, and the reheating time after the end of pouring can be shortened.
The required time can be shortened.

Embodiments Hereinafter, embodiments of the present invention will be described based on the accompanying drawings.

In FIG. 1, the hot water outlet pipe 2 of the instantaneous water heater 1 is connected to the hot water outlet tap 3.
and an outlet pipe 5 having a pouring valve 4,
The outlet pipe 5 faces the hopper 6. The hot water pouring pipe 7 has a hopper 6 on one side, the lower part communicates with the inlet water can part 8 of the bath heater, and the bathtub 9 has an upper circulation pipe 10. Inlet water can section8. Heat exchanger tube 11, outlet water can part 12. Lower circulation vibe 1
They are connected in the order of 3. Further, the water level sensor 14 and the temperature detection sensor 15 are connected to the circulation pump 16 at the outlet water can section 12.
J: part circulation pipe 1
It is provided to have a discharge port 18 in the inside. In addition, 19
is a microcomputer control box incorporating an automatic operation sequence, 20 is a bath remote control for the bathroom, 21 is a main remote control for the kitchen, 22 is an automatic operation switch, and 23 is a reheating switch.

In the above configuration, by turning on the automatic operation switch 22, the pouring valve 4 opens, and the temperature of the instantaneous water heater 1 is set in advance with the main remote controller 21 (hereinafter referred to as set temperature).
The heated fan is connected to the outlet pipe 2, pour valve J 4. It passes through the tapping pipe 5, is dropped into the hopper 6, passes through the pouring pipe 7,
Light blue part of the bath heater 8. Heat exchanger tube 11. Dehi water can part 1
2. The hot water is poured into the bathtub 9 through the lower circulation vibrator 13.

The water level in the bathtub 9 is measured by a water level sensor 14. bathtub 9
When the internal water level reaches t from the position of the partial circulation pipe, the circulation pump 16 is operated to suck in water from the suction port 17 in the heat transfer tube 11 and discharge it from the discharge port 18 in the upper circulation pipe 10. The pumped water in the bathtub 9 is passed through the lower circulation pipe 13. Outlet water can part 12. The temperature of the hot water in the bathtub 9 can be detected by the temperature detection sensor 15. At this time, the poured hot water is also transferred from the inside of the heat transfer tube 11 to the bathtub by the circulation pump 16. FIG. 2 shows a temperature control sequence diagram of the microcomputer control box 19 during pouring. When the temperature inside the bathtub is lower than the set temperature, reheating of the bathtub is started and hot water is poured from the instantaneous water heater 1 into the bathtub 9 at the set temperature in the same manner as in the above-mentioned route. When the water level in the bathtub 9 reaches a preset water level using the main remote controller 21, the hot water pouring valve 4 is closed, it is determined whether the temperature in the bathtub has reached the set temperature, and if the temperature is insufficient, reheating is started. When the set temperature is reached, reheating is stopped, and the circulation pump 16 is also stopped.
Finish on the leg.

By performing automatic operation as described above, if there is water remaining in the bathtub and the water level of the remaining water is lower than the set water level, the remaining water temperature is lower than the set temperature, so reheating is started, After pouring the water to the set water level, reheating is performed to reach the set temperature, so the reheating time after pouring can be shortened by the amount of heat that is reheated during pouring. can be shortened.

Effects of the Invention As described above, according to the present invention, when the automatic operation switch is turned on, in an automatic feeding bath device that pours hot water into the bathtub and raises the legs to the desired temperature, when there is water remaining in the bathtub, the setting temperature is changed. By starting reheating of the bath pot at the same time as pouring hot water, the time required for reheating after pouring can be shortened, and the time required for θ1+ can be shortened.
