Description

Hot Tub Circulator with Reserve Operation {Subscription Thermo Controller Algorithm}

The present invention relates to a hot water temperature control device for a bath for half body bath, more specifically, to adjust the hot water temperature of the bathtub installed in the home, such as 37 ℃ ~ 39 ℃ bathing only between the body and the navel, the lower body is warm The upper half of the body is chilled, and after about 20 to 30 minutes, the hot heat is felt from the inside of the body, which promotes blood circulation, sweat and waste, and the discharge of toxins in the body.

In general, in order to have a half body bath at home, take a bath of hot water of 37 ℃ ~ 39 ℃ in the bath and after a little time, the temperature of the hot water is lowered and the effect of half body bath can not be seen. There is a way to cover the bath cover to compensate for this, but this method also could not prevent the hot water temperature of the bath is lowered. Therefore, recently, a half body bath method using a temperature control device that has a constant temperature between 37 ° C and 39 ° C by adding a heating device has emerged.

However, such a hot water circulation supply device with a thermostat is used to maintain the temperature of hot water 24 hours for users who want to daily half bath due to the nature of the half body bath, or directly supply hot water when needed, or use a heating device when cold water is used. It was necessary to wait until the water temperature rose to a temperature suitable for half body bath before use.

This method is a waste of energy required to maintain the temperature 24 hours and expenses for it is serious, and the direct method of supplying hot water has to be inconvenient to supply hot water whenever necessary, and the water temperature of the bathtub to the temperature required for half body bath If it is under, it is inconvenient to wait until the required water temperature, which requires a lot of time, expense, or effort due to the nature of half-bath, a health desire to be done every day.

Based on these inconveniences and problems, the present inventors have a reservation operation function in the hot water circulation supply device in which a heating device is formed so that a user who wants to have a half body bath can always have a half body bath at a desired time. It is intended to provide a function to automatically operate the heating device so that the water temperature of the bathtub is automatically maintained at the temperature required for the half body bath.

The present invention is a means for solving the technical problem as a hot water reservation operation method of the bath for half body bath, if the user reserves the time that he wants half body bath, the control unit of the hot water circulation supply device is always the water temperature and reservation operation of the bathtub Compare the time with the current time, and calculate the time TDT (estimated rise time of the set temperature rise in Fig. 3) required for the water temperature of the current bath to increase the temperature required for the half body bath (e.g. between 37 ° C and 39 ° C) by operating the heating device. If it is greater than or equal to the time RT subtracted from the current time RT (Fig. 3 remaining time), the heating device operates to raise the water temperature of the bath, so that the water temperature of the bath is required for the half body bath at the desired time. Example: The temperature of the hot water circulation supply device of the bathtub waiting for the user's bathing while maintaining a constant temperature between 37 ℃ ~ 39 ℃) It relates to the scheduled operating temperature control method.

Hereinafter, the hot water reservation operation temperature control method of the present invention with reference to the accompanying drawings in detail as follows.

The hot water reservation operation temperature control method of the present invention, that is, when the user sets the desired time for half body bath and the user desires half body bath, the temperature of the hot water of the bath is required for the half body bath (for example, the set temperature between 37 ° C and 39 ° C) In order to implement a method for controlling the hot water reservation operation temperature of the bath in a bathing state while maintaining a constant temperature after reaching the temperature, the circulation pump 310 for circulating heating the hot water of the bath and a temperature sensing unit for detecting the temperature of the hot water ( 20), the control unit 3 and the operating device of the built-in heating device 300 for heating the hot water to the set temperature and the microcontroller 100 for hot water temperature control of the present invention and the operation of the product is shown The display control unit 2 and the silicone hoses 30b, 30c, 30d, and 30e for the flow of hot water are provided in the main body 1, and the inlet and outlet sills are provided with hot water flowing in and out of the main body. It is connected to the hose (30a, 30f) and the hose is composed of ipsugu 40 and chulsugu 50 is the hot water outlet of the bath.

For example, if the user for half body bath sets the reservation time to 9 pm every hour at 9 pm every evening, the control unit 3 equipped with the microcontroller 100 is at a set temperature (ST in FIG. 3). Calculate the difference between the current water temperature (HT in Fig. 3) and multiply the time (DT) required to raise the temperature by 1 ℃ to the target temperature based on the 250L standard bath water capacity using the heat capacity of the heating device of the hot water supply at the current ambient temperature. The time required for ascent (TDT in Fig. 3) is obtained.

Thus, the microcontroller 100 compares the difference between the regular reservation time, the current time (RT) and the target temperature rise time (TDT) to determine whether the remaining bath bath reservation time (RT) is less than or equal to the target temperature rise time (TDT). If the remaining time (RT) is the same as that of the artist, the user is scheduled to bathe while the water temperature is raised and maintained between the temperature required for half body bath (e.g. 37 ℃ ~ 39 ℃) until the user's bathing. It is a way to eliminate the inconvenience of having to keep hot water at all times to waste energy or to adjust the temperature of hot water whenever the half body bath is needed.

Next, the hot water reservation operation temperature control routine related to the flowchart of FIG. 4 for implementing the reservation operation of the hot water will be described.

The reservation operation temperature control routine checks in step 701 whether the user has set up a bathing reservation. If the bath is not reserved, return without executing the reservation operation temperature control routine. If a reservation is made, the temperature of the current bath water is detected in step 702, and the current ambient temperature, that is, the air temperature in step 703 is detected. If no air temperature detector is provided, the standard temperature is assumed to be 20 degrees.

In step 704, the time DT required to increase the water temperature by 1 ° C is calculated based on the standard bath water quantity 250L based on the heat capacity of the heating apparatus provided under the current ambient temperature. In step 705, the remaining time (RT) until the bathing reservation time is calculated by subtracting the current time from the bathing reservation time. In step 706, the difference between the set temperature of the hot water and the present temperature is obtained, and the total temperature rise time (TDT) up to the set temperature is obtained by multiplying the time DT required when the hot water rises by 1 ° C.

In step 707, if the reservation operation remaining time (RT) is compared with the total temperature rise time (TDT), and if the reservation operation remaining time (RT) is less than or equal to, in step 708, the temperature control of the hot water is started or the hot water temperature control mode flag is set. The hot water is heated to the target set temperature so that the user can immediately bathe for half body bath without waiting time at a predetermined bathing time.

The effects of the present invention require a lot of time and effort to prepare and adjust the temperature of hot water when you want to take half body bath, which is a healthy bath in busy daily life, or waste enormous energy by maintaining the temperature of hot water for 24 hours It is a very useful design that greatly reduces energy savings by heating hot water only when it is needed in the high oil price era.
