TECHNICAL FIELD OF THE INVENTION
The present invention relates to a bath apparatus, particularly to a home bath apparatus.
[0002]
[Prior art]
The conventional bath apparatus has a bath automatic function of filling a predetermined amount of hot water at a temperature set in the bath tub, and there is remaining hot water in the bath tub, and when the temperature of the remaining hot water is lower than the set temperature, the remaining hot water is circulated in the bath. The circuit is heated to the set temperature, the remaining hot water amount is calculated based on the heating time until the set temperature is reached, and the calculated remaining hot water amount is compared with a predetermined amount set in advance. It had a function of dropping hot water and filling a predetermined amount of hot water (for example, see Patent Document 1).
[0003]
A specific example of the hot water filling operation in the conventional bath apparatus will be described with reference to FIG. First, the hot water filling operation is started by pressing the hot water filling start switch of the remote control after setting the hot water amount A and the hot water temperature t of the hot water with the remote control (step S21).
[0004]
Next, it is determined whether there is remaining hot water (step S22). In other words, the bath pump is driven to circulate hot water in the bath circulation circuit, and when the bath water flow sensor detects, it is determined that there is remaining hot water. Is determined.
[0005]
Next, when it is determined that there is no remaining hot water, hot water filling is performed with the set hot water amount A (step S23). That is, the hot water filling valve is opened by the control device, the calorific value of the hot water supply burner is adjusted so as to reach the set temperature t, the product of the detected water amount and the elapsed time is counted, and the cumulative hot water amount is detected. When it becomes A, the hot water filling valve is closed and the hot water filling is stopped.
[0006]
Next, the water is heated to the set temperature (step S24). That is, the bath pump is driven to circulate the hot water in the bath tub and the temperature of the hot water is detected by the bath temperature sensor. If the temperature of the hot water in the bath tub has reached the set temperature t, the process proceeds to the next step S25, If the temperature of the hot water is lower than the set temperature t, the water is heated to the set temperature t.
[0007]
Next, when the set temperature t is reached, notification of completion of hot water filling is made in step S25. That is, the bath pump is stopped, and the display of the remote controller and the buzzer sound notify that the hot water filling is completed.
[0008]
On the other hand, if it is determined in step S22 that there is remaining hot water, it is determined whether the remaining hot water amount can be calculated (step S26). That is, assuming that the temperature of the remaining hot water is t0, if (t−t0) is equal to or more than α (a predetermined temperature difference), it is determined that the remaining hot water amount can be calculated, and the remaining hot water amount detection operation (step S27) ). On the other hand, if (t−t0) is smaller than α, the hot water is filled with the fixed hot water amount C (C <A) (step S30), and the operations of steps S25 and S26 are performed to complete the hot water filling.
[0009]
In step S27, a detection operation of the remaining hot water amount is performed. That is, the remaining hot water in the bath tub is heated for a predetermined time T0 with a predetermined output Q, the temperature rise value Δt is measured, and in the next step S28, the remaining hot water amount B is calculated by the following equation based on those values. .
[0010]
B = k × Q × T0 / Δt (k is a correction coefficient)
Next, after filling the hot water amount corresponding to the difference between the set hot water amount A and the calculated remaining hot water amount B (step S29), the operations of steps S25 and S26 are performed to complete the hot water filling.

[Problems to be solved by the invention]
However, in the conventional bath apparatus, even if there is remaining hot water in the bathtub, if the difference between the hot water temperature t0 and the set temperature t is less than α, the remaining hot water amount cannot be calculated, so the fixed hot water amount C (C <A) It was completed with hot water. Therefore, there is a problem that the user needs to add hot water by another method in order to fill the set amount of hot water, or to drain the remaining hot water once and redo the hot water again, which is inconvenient.
[0013]
In addition, since it is not possible to recognize that the hot water of the set amount has not been filled due to the condition of the remaining hot water, there is also a problem that the device is erroneously recognized as a device failure.

Before the start of the beam, perform the flushing operation for an arbitrary time, calculate the remaining hot water amount with the temperature rise value of the remaining hot water and the value of the flushing output in the meantime, and subtract the calculated remaining hot water amount from the set hot water hot water amount. In a bath device with a function of hot water removal, in a condition where the amount of remaining hot water cannot be accurately calculated from the temperature of the remaining hot water and the set temperature, an arbitrary fixed amount of hot water is filled, and a remote control indicates that the calculation could not be performed accurately. It has the function of notifying with.
[0016]
According to this configuration, in order to fill the set amount of hot water, even if there is remaining hot water, the amount is calculated and the hot water is sprinkled, so that there is no inconvenience such as having to drain the remaining hot water once, If the remaining hot water volume cannot be calculated accurately, a certain amount of hot water is supplied and the user is notified that the hot water volume is not the set amount, thereby preventing erroneous recognition that the equipment is out of order. In addition, the user can take corrective action.
[0017]
In addition, if the user has a function of notifying that the remaining hot water could not be calculated by continuing the buzzer sound of the remote controller and the blinking of the lamp for an arbitrary time, the user can surely know that the hot water of the set hot water cannot be filled. be able to.
[0018]
Also, if a function is provided to inform the user of the fact that the remaining hot water could not be calculated and how to deal with it by voice guidance on the remote control, the user can more accurately know that the set hot water cannot be filled with hot water and various measures. Can be.
[0019]
Further, in the case of a condition in which the remaining hot water amount cannot be calculated from the temperature of the remaining hot water and the set temperature, the remaining hot water is not calculated, and hot water obtained by subtracting an arbitrary fixed amount of hot water from the set hot water is not calculated. With the function of notifying the user with a remote control, even if the remaining hot water cannot be calculated, it is possible to fill the hot water with the amount of hot water that can be taken.
[0020]
In addition, when the remaining hot water amount cannot be calculated from the remaining hot water temperature and the set temperature, the remaining hot water is not calculated, the remote control is notified that the calculation was not possible, and the remaining hot water calculation function is operated by a remote control switch operation. With a function that waits for a certain period of time in a state where it can be invalidated and has a function to supply a certain amount of hot water if the switch operation is not performed for a certain period of time, if the remaining hot water amount can not be calculated, a certain amount of hot water even if the user does not notice You can remove hot water.
[0021]
In addition, when a switch is provided for switching whether or not to calculate the remaining hot water, the user can select a hot water filling method in advance.
[0022]
In addition, in a condition that the remaining hot water amount cannot be accurately calculated from the temperature of the remaining hot water and the set temperature, the fact that the calculation cannot be performed accurately is notified by the remote controller, and the standby operation is performed in a state where the remaining hot water calculation can be invalidated by a switch operation of the remote controller. With the function, when accurate calculation of the remaining hot water cannot be performed, the hot water can be filled with the amount of hot water according to the user's plan.
[0023]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of a bath apparatus of the present invention will be described with reference to FIGS.
[0024]

A bath burner that generates heat to be generated, 11 is a bath heat exchanger that transfers the heat generated by the bath burner 10 to hot and cold water in a bath circulation circuit, 12 is a hot and cold water temperature sensor that detects hot and cold water temperature, and 13 is a hot water supply temperature sensor. Hot water supply heat exchanger transferring heat to, 14 is a hot water supply burner for generating heat for heating the feed water.
[0025]
Next, the hot water filling operation in the bath apparatus having the above configuration will be described with reference to FIGS.
[0026]
First, the hot water filling operation is set to A and the hot water temperature is set to t on the remote controller 3, and when the hot water filling start switch of the remote controller 3 is pressed, the hot water filling operation is started (step S1).
[0027]
Next, it is determined whether there is remaining hot water (step S2). That is, first, the bath pump 7 is driven to circulate the hot water in the bath circulation circuit for a certain period of time. When the remaining hot water in the bathtub 5 reaches above the circulation adapter 6, hot water circulates in the bath circulation circuit, and the bath water flow sensor 8 detects the hot water, and determines that there is remaining hot water. If the remaining hot water in the bathtub 5 is lower than the circulation adapter 6, the hot water does not circulate in the bath circulation circuit, and the bath water flow sensor 8 does not detect even after a certain period of time, and it is determined that there is no remaining hot water. .
[0028]
Next, when it is determined that there is no remaining hot water, hot water filling is performed with the set hot water amount A (step S3). That is, when the hot water filling valve 4 is opened by the control device 1, water flows in the hot water supply circuit, which is detected by the water amount sensor 2, the hot water supply burner 14 is ignited, and the water is heated by the hot water supply heat exchanger 13. The temperature of the heated hot water is detected by the hot water supply / discharge temperature sensor 12, and the control device adjusts the calorific value of the hot water supply burner 14 so as to reach the set temperature t. Further, the controller 1 accumulates the product of the amount of water detected by the water amount sensor 2 and the elapsed time, and counts the amount of hot water. When the accumulated hot water amount reaches the set hot water amount A, the hot water filling valve 4 is closed and the hot water filling is stopped.

Next, boiling is performed to the set temperature t (step S4). That is, the bath pump 7 is driven, the hot water in the bathtub 5 is circulated, and the temperature of the hot water is detected by the bath temperature sensor 9. If the temperature of the hot water in the bathtub 5 has reached the set temperature t, the process moves to the next step S5. If the temperature of the hot water in the bathtub 5 is lower than the set temperature t, the bath burner 10 is ignited, and the hot water in the bathtub 5 is heated by the bath heat exchanger 11 to the set temperature t.
[0030]
Next, notification of completion of hot water filling is performed (step A5). That is, the bath pump 7 is stopped, and the display of the remote controller 3 and the buzzer sound notify that the hot water filling is completed.
[0031]
On the other hand, when it is determined in step S2 that there is remaining hot water, it is determined whether or not calculation of the remaining hot water amount is possible (step S6). That is, assuming that the temperature of the remaining hot water is t0, if (t−t0) is equal to or more than α (a predetermined temperature difference), it is determined that the calculation of the remaining hot water amount is possible, and the operation proceeds to the remaining hot water amount detection operation in step S7. Transition. On the other hand, if (t−t0) is smaller than α, the process proceeds to step S10.
[0032]
In step S7, the remaining hot water in the bathtub 5 is heated for a predetermined time T0 at a predetermined output Q, and the temperature rise value Δt is measured. Next, based on these values, the remaining hot water amount B is calculated by the following equation (step S8).
[0033]
B = k × Q × T0 / Δt (k is a correction coefficient)
Then, the hot water corresponding to the difference between the set hot water amount A and the calculated remaining hot water amount B is filled (step S9), and the operations of steps S4 and S5 are performed to complete the filling.
[0034]
If there is remaining hot water in the bathtub 5 but the amount of remaining hot water cannot be calculated, it is displayed on the display unit of the remote controller 3 in step S10, and a buzzer sound or blinking of a lamp is continued for an arbitrary period of time. Then, the user is notified without fail and the process proceeds to step S11.
[0035]
In step S11, the user stands by for a predetermined time T in a state in which the operation can be switched. When the changeover switch is pressed, the remaining hot water calculation function is disabled, and the fixed amount D (virtual remaining hot water amount) is separately subtracted from the set hot water amount A. The amount of hot water is calculated and the hot water is filled (step S12), and the operations in steps S4 and S5 are performed to complete the operation. Thereby, even if it is not possible to calculate the remaining hot water, it is possible to fill the hot water with a sufficient amount of hot water.
[0036]
On the other hand, if the user does not press the changeover switch for a certain period of time, the hot water is fixed at the fixed hot water amount C (step S13), and the operations in steps S4 and S5 are performed, and the process is completed. By providing the changeover switch in this way, the user can select a hot water filling method in advance even when the remaining hot water amount cannot be calculated.
[0037]
In the description of the above-described embodiment, an example has been described in which when the remaining hot water amount cannot be calculated, the remote controller 3 notifies the outside to perform the fixed hot water amount (A-D) or the hot water filling of C, but in addition thereto, the remaining hot water amount May be notified by the voice guidance of the remote controller, and the user can more accurately know that the set hot water volume cannot be filled, and can take various measures.
[0038]
Further, a switch may be provided on the remote controller 3 or the like to switch whether or not to calculate the remaining hot water, so that the user can select a hot water filling method in advance.
[0039]
Further, in a condition where the remaining hot water amount cannot be calculated accurately from the temperature of the remaining hot water and the set temperature, it is notified by the remote controller 3 that the remaining hot water cannot be calculated accurately, and the remaining hot water calculation can be invalidated by a switch operation of the remote controller 3. A function of waiting may be provided, and in the case where accurate calculation of the remaining hot water cannot be performed, the hot water can be filled according to the user's plan.
