PURPOSE:To permit the securing of the amount of hot-water for shower and the starting of automatic hot-water supplying operation automatically after the shower is used, by a method wherein, a hot-water supplying circuit and an automatic hot-water supplying circuit, which supplies hot-water automatically into a bathtub, are formed so as to be branched at the delivery side of a hot-water supplier while the amount of hot-water in a hot-water supplying circuit is given with priority to the automatic hot-water supplying circuit upon using both circuits simultaneously. CONSTITUTION:When a shower cock 21 is opened in order to use a shower 20 during automatic hot-water supplying operation, hot-water heated by a hot-water supplier 11, flows through a hot-water supplying circuit 22, a flow rate switch 19 is put ON, a automatic hot-water supplying valve 13, provided in an automatic hot-water supplying circuit 26, is put OFF and the hot-water from the supplier 11 flows through the hot-water supplying circuit 22 only. On the other hand, when the use of the shower 20 is stopped and the shower cock 21 is closed, the hot-water from the hot-water supplier 11 does not flow through the hot-water supplying circuit, the flow rate switch 19 is put OFF, the automatic hot-water supplying valve 13 is put ON and the hot-water flows through the automatic hot-water supplying circuit 26 to continue the automatic hot-water supply for a bathtub 16 until a water level sensor 17 detects that a water level has achieved the set water level of the bathtub 16 and is put OFF.

Description

[Detailed description of the invention] 3. Detailed explanation of the invention Industrial application field 2 B/ The present invention improves the usability of automatic hot water supply (filling the bathtub) and manual hot water supply (using the kitchen and shower). This article relates to a bathtub device with a heater for general household use.

2. Description of the Related Art In general, in an automatic bath system with a water heater, as shown in FIG.
A hot water supply circuit 3 is provided, and the other is an automatic hot water supply valve 6 that opens and closes in conjunction with the water level sensor 5 to automatically supply hot water to the bathtub 4 at the water level set by the water level sensor 5, and a hopper 7 to a bath pot 8. It consists of an automatic hot water supply circuit 9 leading to the bathtub 4.

In these bath apparatuses with a water heater, when the water level of the bathtub 4 decreases using the station of the bathtub 4, the water level is automatically replenished and maintained at the water level set by the water level sensor 5.

In addition, since the shower 2 is used, if the shower faucet 10 is opened, the shower 2 will also be activated and the user can use the shower.

Problems to be Solved by the Invention However, there are 31.-
In No. 7, the shower 2 is used during the automatic hot water supply operation, so even if the shower faucet 10 is opened, the amount of hot water in the shower 2 is insufficient and the shower cannot be used. (5th
In the usage/operation mode between B and C in the figure, the flow rate is distributed between the flow rate shown in the F diagram showing the shower flow rate in FIG. 6 and the flow rate shown in the E diagram showing the automatic hot water supply flow rate. ) Depending on the bathing condition, if the automatic hot water supply operation is activated while the shower is in use, the amount of hot water in the shower becomes extremely small, causing problems such as the shower becoming unusable. Generally, the pressure loss of the shower opening is large and the position of the shower opening is high, so the positional water head is added and the flow rate is reduced.

For this reason, conventionally, when using a shower, there was a problem that the shower could only be used by turning off the automatic hot water supply operation switch or while the automatic hot water supply operation was stopped.

The present invention solves these conventional problems.The present invention has an hour wheel configuration, so that automatic hot water supply operation does not start while the shower is in use, and even when automatic hot water supply operation is in progress, the shower faucet does not close. We provide an automatic bath device with a water heater that allows you to stop the automatic hot water supply operation by simply opening the door, ensuring a sufficient amount of hot water for the shower, and automatically starting the automatic hot water supply operation after using the shower. An automatic bath system with a device is formed by branching a hot water supply circuit that leads to a shower faucet, etc. and an automatic hot water supply circuit that automatically supplies hot water to the bathtub to the hot water outlet side of the water heater, and when both circuits are used simultaneously, the li of the hot water supply circuit is automatically switched off. It is configured to give priority to the hot water supply circuit.

Effect: According to the means of the present invention, when the circuit and the automatic hot water supply circuit are used simultaneously, the amount of hot water in the hot water supply circuit has priority over the automatic hot water supply circuit, so that the automatic hot water supply operation starts while the shower is being used, and the shower cannot be used. Even if you use the shower during automatic hot water supply operation, you can still get a sufficient amount of hot water.

EXAMPLE Hereinafter, an automatic bath apparatus with a water heater according to an example of the present invention will be explained with reference to the drawings.

5-7 As shown in FIG. 1, the hot water outlet side 12 of the water heater 11 is branched, and one side is connected from the automatic hot water supply valve 13 to the hot water heater 14 to the bath pot 15.
It is equipped with an automatic hot water supply circuit 26 that automatically supplies hot water to the bathtub 16 via the water level sensor 17 that detects the water level of the bathtub 16, and the water level reaches the set water level set by the controller 23 of the remote controller that receives this signal. The automatic hot water supply valve 13 is operated to maintain the water level in the bathtub 16. On the other hand, a flow rate switch 19 is provided between the hot water outlet side 12 of the water heater 11 and the hot water supply connection port 18 to detect the amount of hot water output. A hot water supply circuit 22 is constituted by a shower faucet 21 for opening and closing hot water supply to the shower.

In the embodiment, hot water flows through the hot water supply circuit 22 and the flow rate switch 1
The controller 23 receives the signal from the flow rate switch 19 so that the automatic hot water supply valve 13 is set to 1OFFj when 9 is "ON".
It is now controlled by.

In this way, in order to use the shower 20 during automatic hot water supply operation, if you open the shower faucet 21, 6 l.
- Hot water heated by the water heater 11 flows into the hot water supply circuit 22, the flow rate switch 19 is set to 0N-1, and the automatic hot water supply valve 13 provided in the automatic hot water supply circuit 26 is set to [○FF l l,, water heater 1].
Since the hot water from 1 flows only to the hot water supply circuit 22, a sufficient amount of hot water from the shower 20 is ensured and the shower can be used. (The flow rate will be as shown in the operating state between 0 and 1 in Figure 2 and the flow rate characteristics in Figure 3.) Also, if you stop using the shower 20 and close the shower faucet 21, the height from the vessel 11 will eventually decrease. There is no flow to the hot water supply circuit, the flow rate switch 19 is set to [0FFjL, and the automatic hot water supply valve 13 is set to [0
N-1, the station flows to the automatic hot water supply circuit 26, and the water level sensor 1
7 detects that the set water level of the bathtub 16 has been reached and turns rO
Automatic hot water supply to the bathtub 16 continues until FFj is reached.

Furthermore, even if the water level in the bathtub 16 drops while the shower 20 is in use and the water level sensor 17 is turned on, the flow rate switch 19 has already been turned on and the automatic hot water supply valve 13 is turned off, so the automatic hot water supply circuit 26 remains closed and the automatic hot water supply operation is not started but is on standby.

Therefore, it is possible to secure a sufficient amount of hot water for using the shower 20 during automatic hot water supply operation, and there is no need to operate an operation switch or the like to cancel automatic hot water supply operation, and usability can be improved. In addition, since the automatic hot water supply operation does not start while the shower 20 is in use, the shower 20 can be used with a sufficient amount of hot water as described above, and after the shower 20 is used, the automatic hot water supply operation is performed to the set water level in the bathtub 16. Therefore, the water level in the bathtub can be maintained without having to operate it every time. In addition, 24 in the figure is a sensor that detects the flow rate flowing to the feeder 11 with the flow rate switch B and sends a signal for ignition operation to the controller 23. Upon receiving this signal, the controller controls the ignition device to ignite the burner. It sends a signal. 2
5 is an exterior case of the water heater 11 and the bath pot 15.

Effects of the Invention As described above, when the hot water supply circuit and the automatic hot water supply circuit are used at the same time, the present invention secures the amount of hot water in the hot water supply circuit by giving priority to the automatic hot water supply circuit, so that a shower or the like is used. Even if automatic hot water supply is started, the amount of hot water in the hot water supply circuit can be sufficient for showers, etc., and conversely, even if the hot water supply circuit is used midway through automatic hot water supply, the required amount of hot water can be immediately secured, which is very effective. It will be easier to use showers, etc.

In addition, by turning on and off the flow rate switch provided in the water supply circuit that supplies water to shower faucets, etc., the automatic hot water supply valve of the automatic hot water supply circuit that supplies water to bathtubs, etc., is turned on and off.
If configured to open and close in an inverse relationship to N and OFF, the following effects can be expected.

In other words, even during automatic hot water supply operation, it is possible to automatically stop the automatic hot water supply and use the shower with a sufficient amount of hot water.
Further, even if the water level in the bathtub drops while using the shower, the automatic hot water supply operation starts only after the shower is used, so the shower can be used with a sufficient amount of hot water as in the above case, improving usability.

Furthermore, there is no need to perform operations such as stopping the automatic hot water supply operation before using the shower, and there is no need to reoperate the switch for the automatic hot water supply operation when using the shower. This makes it possible to provide a highly practical and highly advantageous device.
