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 rise the temperature of pouring hot-water than the set temperature 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 the set temperature, hot-water, having a temperature higher than the set temperature by several degrees, is poured. When the water level in the bathtub 9 has become a set water level, the hot-water pouring valve 4 is closed. When the temperature of hot-water in the bathtub is decided whether it has arrived at the set temperature or not and it is lower than the set temperature, additional heating is started. When the set temperature of hot-water in the bathtub has been achieved, the additional heating as well as the operation of the circulation pump 16 are 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 water to a preset water temperature with 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 there is residual water in the bathtub from the previous day that is lower than the set water level, hot water at a constant temperature is not poured into the bathtub. After the addition of heat, reheating is performed until the set level is reached, which has the problem of increasing the time required to heat the r4 f:.

In order to solve the problem, while hot water at a set temperature is being poured into the bathtub from the instantaneous water heater, the pumped water in the bathtub is circulated through the equipment using a pump. This system is equipped with a microcomputer that detects the temperature of hot water in the bathtub and, when the temperature of the hot water in the bathtub is lower than the set temperature, pours hot water at a temperature higher 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 after pouring water at a temperature higher than the set temperature to the set water level, Since reheating is performed up to the set temperature, the reheating time can be shortened by the amount of heat poured at a temperature higher than the set temperature, and the time required for boiling 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 at the end, and the lower part communicates with the sunrise water can part 8 of the bath heater, and the bathtub 9 has a seven-part ring pipe 10. Inlet water can section8. Heat exchanger tube 11, outlet water can part 12. Lower circulation pipe 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.
The inlet 17 is placed inside the heat transfer tube 11, and the circulation pipe 10 is placed in the h section.
It is provided with a discharge port 18 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, when the automatic operation switch 22 is turned on, the hot water pouring valve 4 opens, and when the hot water is heated to the temperature (hereinafter referred to as set temperature) preset with the main remote control 21 in the instantaneous field dIi device 1, the hot water is poured out. Pipe 2, pouring valve 4. Hot water tap 5
The hot water is dropped into the hopper 6, passes through the pouring pipe 7, and enters the bath heater's paddy field 8. Heat exchanger tube 11. Dehi water can club 12. The hot water is poured into the bathtub 9 through the lower circulation pipe 13. The water level in the bathtub 9 is measured by a water level sensor 14. When the water level in bathtub 9 rises above the position of the seventh lock ring pipe,
By operating the circulation pump 16, water is drawn in through the suction port 17 in the heat exchanger tube 11, and discharged from the discharge port 18 in the partial circulation pipe 10, thereby pumping water in the bathtub 9 into the lower circulation pipe 13. Outlet water can part 12. It can be circulated with the heat exchanger tube 11, and the temperature of the pumped water in the bathtub 9 can be detected by the temperature detection sensor 15. At this time, the place where the hot water is being poured is also transferred from the inside of the heat transfer tube 11 to the bathtub by the circulation pump 16. FIG. 2 shows a sequence diagram for controlling the pouring temperature of the microcomputer control box 19 during pouring. When the temperature inside the bathtub is lower than the set temperature, the capacity of the instant water heater 1 is increased and hot water is poured into the bathtub at a temperature several degrees higher than 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 with the main remote control 21, the hot water pouring valve 4 is closed, and it is determined whether the temperature in the bathtub has reached the set temperature, and if it is insufficient, reheating is performed. After the reheating is stopped when the set temperature is reached, the circulation pump 16 is also stopped, and the leg raising is completed.

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 temperature of the remaining water is lower than the set temperature, so the temperature higher than the set temperature is After pouring hot water to the set water level, reheating is performed to the set temperature, so the reheating time can be shortened by the amount of heat generated by pouring hot water at a temperature higher than the set temperature, and the time required in %B 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 water into the bathtub and raises the legs to the desired temperature, when there is water remaining in the bathtub, the temperature is lower than the set temperature. By pouring hot water at a higher temperature, it is possible to shorten the reheating time after pouring the hot water and shorten the time required for heating the pot.
