DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bath kettle apparatus.

[0002]

2. Description of the Related Art There have been provided a large number of bath tub devices for circulating bath water to a bath tub with a circulating pump for heating and for automatically pouring hot water into the bath tub.

[0003]

In the above-mentioned bath-tank apparatus, particularly in the case of a long circulating (reheating) pipe using a circulating pump, even if the water in the bathtub is drained, the water in the circulating pipe is difficult. It does not come off and gradually comes out to the bathtub side by replacement with air. Therefore, especially in the case of a wooden bathtub, there is a problem that the vicinity of the circulating metal fittings of the bathtub does not dry, and water scale is generated and trees are rotten.

Accordingly, the present invention has been made to solve the above-mentioned drawbacks of the prior art, and to provide a bathtub apparatus capable of suppressing the bathtub from drying quickly after drainage and preventing the bathtub from becoming scaled and the bathtub trees from rotting. Aim.

[0005]

To achieve the above object, according to an aspect of, bathtub apparatus of the present invention are the bath water level detection mechanisms, the circulation path for circulating the water between the bath tank and the bathtub, a circulation pump Circulating metal fittings on the side wall of the bathtub
At least a controller to perform bath water circulation
Circulated from the circulation fitting to the bath
In addition to reheating, the bottom of the bathtub is drained.
To drain the bathtub water by opening the drain plug provided in
A bath kettle device, wherein the controller is
Bathtub water is below the circulating bracket by the bathtub water level detection mechanism.
And monitor bath water drops below the circulating bracket.
If it drops, the circulation pump is automatically operated for a certain period of time.
It is characterized by the configuration .

[0006]

[Function] When the bathtub water level is lower than the circulating bracket when the bathtub water is drained, the circulating pump is driven for a certain period of time, whereby the water remaining in the circulating passage is forcibly drained, and the piping is extended for a long time. It is possible to prevent the residual water from flowing out.

1 is an overall configuration diagram of a bath kettle apparatus according to the present invention, FIG. 2 is a flowchart showing an example of operation control when a bath is supplied by a controller, and FIG. 3 is an example of operation control when a bath is drained by a controller. It is a flowchart.

The bathtub 1 has a circulation fitting 2 at an appropriate water level.
And a drain plug 3 is provided at the bottom. On the other hand, a bath heat exchanger 4 is provided with a bath heat exchanger 5 and a burner 6 thereof, a hot water supply heat exchanger 7 and a burner 8 thereof, and is provided between the bath heat exchanger 5 and the circulation fitting 2. A circulation path 9 for burning is provided. The circulation path 9 is provided with a water level sensor 10 for detecting a bathtub water level, a bath water flow switch 11, and a circulation pump 12. A water inlet pipe 13 and a hot water supply pipe 14 are connected to the heat exchanger 7 for hot water supply,
3 is heated by the hot water supply heat exchanger 7 and is supplied to the hot water supply pipe 14.
Hot water is supplied from. The water supply pipe 13 is provided with a hot water supply water flow switch 15. A bath water supply pipe 16 branches off from the middle of the hot water supply pipe 14, and is connected to the circulation path 9 through a water amount sensor 17, a bath water supply electromagnetic valve 18, and a vacuum breaker 19. When automatically supplying hot water to the bath, the bath hot water supply pipe 16 is used.

The control of the apparatus is performed by a controller 20 and a remote controller 30 built in the microcomputer. The controller 20 inputs information from the remote controller 30, the water level sensor 10, the bath water flow switch 11, the hot water flow switch 15, the water quantity sensor 17, and the like, and sends the information to the burners 6, 8, the circulation pump 12, the bath hot water electromagnetic valve 18, and the like. Output a control signal.

The control of each part of the bath kettle when hot water is supplied to and discharged from the bathtub 1 by the controller 20 will be described with reference to FIGS. Referring to FIG. 2, when the pouring switch is turned on by the remote controller 30 (step 51), the controller 20 first opens the bath hot water supply electromagnetic valve 18 and supplies a predetermined fixed amount, for example, as shown in FIG. 10 liters are poured into the bathtub 1 (step 52). When the water sensor 17 detects 10 liters, the controller 2
In the case of 0, the electromagnetic valve 18 is closed and the circulation pump 12 is turned on for a predetermined time (step 53). Then, it is determined whether or not the bath water flow switch 11 is turned on (step 5).
4) If it is turned on, the water level at that time is detected by the water level sensor 10 and stored as the water level of the circulation fitting 2 (step 55). If off at step 54, steps 52 to 54
repeat. When the water is poured to the target water level (Step 5
6), close the solenoid valve 18 and end the bath hot water supply operation.

Next, control of the controller 20 during drainage will be described with reference to FIG. During operation, the controller 20 constantly inputs the water level information from the water level sensor 10 and monitors whether the bathtub water level is lower than the water level of the circulation fitting 2 stored during the previous water supply operation (step 61).
When the water level falls below the circulation fitting 2 due to the opening of the drain plug 3, the circulation pump 12 is turned on for a certain time at that time (step 62). By this step 62, the circulation path 9
Water remaining in the bath is forcibly discharged into the bathtub 1 by the pump 12, and thereafter, leakage of the residual water from the bathtub from the circulation path 9 is eliminated.

The means for detecting and storing the water level of the circulation fitting 2 is not particularly limited.

[0013]

The present invention has the above-described structure and operation. According to the bath kettle device of the first aspect, when the bathtub water is drained,
When the bathtub water level falls below the circulating bracket, the circulating pump is driven for a certain period of time, so that the water remaining in the circulating channel is forcibly and promptly drained, and the residual water in the piping gradually decreases over a long period of time. Outflow is prevented. Therefore, the bathtub dries quickly after drainage, and it is possible to suppress the occurrence of water scale in the bathtub and the deterioration of the wooden bathtub.
