制循環式浴槽の調温装置を提供するものである。[Detailed explanation of the invention] This invention connects a bathtub and a heat exchanger with a circulation pipe, and uses a pump to forcefully circulate and heat the hot water in the bathtub to boil the bath. This relates to forced circulation bathtubs that measure the temperature of the bathtub, compare the detected temperature with the set temperature, and then turn on and off the burner depending on the temperature to maintain the water temperature in the bathtub at a constant level. To provide a temperature control device for a forced circulation bathtub, which minimizes heat radiation loss accompanying circulation of hot water after reaching temperature and power consumption of a pump.

ンプの消費電力も多く極めて不経済であつた。 Various types of forced circulation bathtubs have been proposed in the past that are equipped with temperature control devices to maintain the water temperature at a constant temperature. Because of this difference, even after the water reaches the set temperature, the pump is constantly operated to stir and circulate the water to measure the water temperature, and the temperature is adjusted based on this detected temperature. Therefore, the heat radiation loss in the circulation pipe and the heat exchanger is large, and the power consumption of the pump is also large, making it extremely uneconomical.

したものである。 This idea was aimed at solving the above-mentioned drawbacks, and in a forced circulation bathtub, a temperature detector was installed in the circulation pipe, and a temperature setting device was installed in the bathroom, etc., and the set temperature was adjusted by the temperature setting device. It has a built-in circuit that stops burner combustion and pump rotation when the temperature detected by the temperature detector is reached.
After the set temperature is reached, the pump is rotated after a certain period of time has passed, the hot water is circulated, the water temperature is averaged, the temperature is measured with a temperature detector, the detected temperature is compared with the set temperature, and the detected temperature is determined to be the set temperature. If the temperature has dropped by more than the allowable temperature difference, the pump will continue to operate and a combustion command will be issued to the burner blinker.
If the temperature is within the allowable temperature difference between the set temperatures, a control device with a built-in circuit that issues a command to stop the rotation of the pump and repeats this series of operations is installed on the pump, temperature detector, blinker, and temperature control device. It is connected to a setting device.

接続した構成である。 In the figure, 1 is a bathtub, A is a bath pot, and 2 is a circulation pipe that connects the bathtub and the heat exchanger 3 of the bath pot A. A pump 4 installed in the circulation pipe 2 supplies hot water in the bathtub to a lower circulation pipe 2a. The temperature of the hot water is detected by a temperature detector 5 installed in the lower circulation pipe 2a, and the hot water is sent to the heat exchanger 3. A burner 6 is located below the heat exchanger 3.
is installed, combustion and extinguishing are controlled by the flasher 7, and hot water heated by the heat exchanger 3 as the burner 6 burns is sent back to the bathtub 1 through the upper circulation pipe 2b. It's getting old. Reference numeral 9 denotes a temperature setting device installed in a bathroom or the like, and the water temperature is adjusted by a control device 8 based on the temperature set by this device and the temperature detected by the temperature detector 5 described above. . The control device 8 has a built-in circuit that stops the combustion of the burner 6 and the rotation of the pump 4 when the temperature reaches the temperature set by the temperature setting device 9, and also keeps the temperature constant after reaching the temperature set by the temperature setting device 9. A circuit rotates the pump 4 after time T 1 , and a temperature sensor 5 after time T 2 when the hot water is sufficiently circulated after the pump 4 is activated and the temperature of the water in the circulation pipe 2 and the bathtub 1 is averaged. The detected temperature is compared with the set temperature, and if the hot water temperature has fallen below the allowable temperature difference between the set temperatures, the pump 4 continues to operate and a combustion command is issued to the flasher 7 of the burner 6. , a built-in circuit that issues a command to stop the pump 4 when the temperature difference is within the allowable temperature difference between the set temperatures. This control device 8 is connected to the above-described temperature detector 5, pump 4, flasher 7, and temperature setting device 9.

差なく調温することができる。 With the above configuration, when water is supplied to the bathtub 1, a desired temperature is set with the post-temperature setting device 9, and the ignition operation is performed, the control device 8 sends a signal to the flasher 7 of the burner 6 and the pump 4 since the temperature is initially below the set temperature. is emitted, the burner 6 combusts, and the water flowing through the heat exchanger 3 is heated, and the rotating operation of the pump 4 causes the water in the bathtub 1 to be sucked into the heat exchanger 3 by the lower circulation pipe 2a.
The heated hot water is sent to the upper circulation pipe 2b.
The water is forcibly delivered into the bathtub 1 through the process. In this way, the water temperature gradually rises, and the lower circulation pipe 2
The temperature detected by the temperature detector 5 installed in the controller 8 is compared with the set temperature by the temperature setting device 9, and when the set temperature is reached, the control device 8 should stop the combustion of the burner 6 and the operation of the pump 4. A command is issued, and the blinker 7 is activated to stop the combustion of the burner 6 and also stop the rotation of the pump 4. Thereafter, after a certain period of time T1 has elapsed, the control device 8 issues a command to operate the pump 4, and the pump 4 operates.
When the hot water is sufficiently circulated and stirred in the bathtub 1 and circulation pipe 2 and the temperature of the hot water is equalized (T 2 after pump operation)
time), the detected temperature from the temperature detector 5 and the set temperature are compared, and if the temperature has fallen below the allowable temperature difference between the set temperatures, the pump 4 continues to operate and the burner 6 is re-combusted. When the water temperature reaches the temperature set by the temperature setting device 9, the pump 4 is turned on as described above.
The rotation of the burner 6 is stopped, and the combustion of the burner 6 is also stopped. Further, if the temperature difference is within the allowable temperature difference between the set temperatures, the rotation of the pump 4 is stopped. Similarly, for a certain period of time again
After T 1 , the pump 4 is operated, the detected temperature is compared with the set temperature, and depending on whether the temperature is within the allowable range, the burner is blinked to adjust the hot water temperature. (See FIG. 2) By repeating these operations, the temperature of the water in the bathtub can always be automatically adjusted to within the allowable temperature difference of the set temperature without error.

ができる等実益の多い考案である。 As mentioned above, according to this invention, after the set temperature is reached (boiled up), not only the combustion of the burner but also the operation of the pump is stopped, and then the pump is started after a certain period of time. However, when the hot water is circulated and the water temperature has averaged out, the temperature is measured and the detected temperature is compared with the set temperature, and the pump and burner are controlled depending on the temperature, so the pump operates only when the temperature is measured and when the burner is burning. This will circulate the hot water. Therefore, the water temperature can be detected without error.
This invention has many practical benefits, such as reducing heat radiation loss in circulation pipes and heat exchangers, and reducing power consumption of pumps.
