Description

DETAILED DESCRIPTION OF THE INVENTION (A) Industrial application field The present invention stops the dropping when the bathtub water level reaches a set water level, and additionally reheats the bathtub hot water to a set temperature while forcibly circulating the bathtub water. About.

(B) Conventional technology Conventionally, as an embodiment of a forced circulation bath kettle device, there is a fully automatic bath kettle device A in which a bath kettle 2 is installed near a bathtub body 1 as shown in FIG.

Such a fully automatic bath kettle device A includes a bath kettle body 4 which is a burner.
By heating by 4a, the hot water in the bathtub main body 1 is circulated to the bathtub main body 1 through a natural circulation path consisting of the bathtub main body 1 → return pipe 3 → bath pot main body 4 → going pipe 5 to gradually raise the temperature of the bath water can do.

In addition, the fully automatic bath apparatus A is provided with a forced circulation path 6 for the purpose of promoting the circulation of the natural circulation path and for the purpose of stirring the hot water in the bathtub body 1.

That is, the forced circulation path 6 is provided with a pump 7 in the middle thereof,
By driving the pump 7, a part of the hot water flowing from the return pipe 3 is sucked from a hot water suction part 6 a provided at one end of the forced circulation path 6, and thereafter, the bath provided at the other end of the forced circulation path 6. The hot water can be discharged from the hot water discharge section 6b and bypassed directly to the going pipe 5 without passing through the bathtub main body 4.

Also. The above-mentioned bath hot water suction section 6a and bath hot water discharge section 6b are opened near the return pipe 3 connecting the bath kettle main body 4 and the bathtub main body 1 and inside the going pipe 5, respectively.

Further, as shown in FIG. 3, a detecting portion 8a of a water level detecting sensor 8 is provided in the bathtub main body 4, and the water pressure in the bathtub main body 4 is guided by the outlet pipe 9, and the set water pressure is obtained. If detected, an ON signal is sent to the control unit 11 (not shown), and the drop valve 10 can be closed.

(C) Problems to be solved by the invention However, the above-described fully automatic bath kettle device still has the following problems to be solved.

That is, when the pump 7 is driven in order to improve the stirring effect at the time of additional heating or the like, the bath water is sucked into the forced circulation path 6 from the bath water suction part 6a provided at one end of the forced circulation path 6. ,
By such suction, not only in the vicinity of the bath water suction part 6a,
The pressure drop also occurs in the detection unit 8a of the water level detection sensor 8.

That is, as shown in FIG. 4, when the pump 7 is turned on,
The water pressure detected by the water level detection sensor 8 drops significantly, and when the pump 7 is turned off again, the water level detection sensor 8 detects a normal water pressure.

As described above, when the pump 7 is in the ON state, the water level detection sensor 8 cannot accurately detect the bath water level in the bathtub main body 1, causing a malfunction and performing a set amount of hot water or hot water. Can not be done.

An object of the present invention is to provide a fully automatic bath kettle device that can solve the above-described problems.

(D) Means for Solving the Problems The present invention relates to a bathtub body, a bath kettle installed near the bathtub body, an access pipe for sending hot water from the bathtub body to the bathtub body, and a bathtub. A natural circulation path that circulates hot water by connecting with a return pipe for sending hot water from the main body to the bath kettle main body, and a forced circulation path that bypasses the return pipe of the natural circulation path to the going pipe, And in the fully automatic bath apparatus having a water level detection sensor for detecting a bathtub water level by water pressure, the bath water body is provided between a detection part of the water level detection sensor and a hot water suction part of the forced circulation path. The present invention relates to a fully automatic bath kettle apparatus having a partition plate interposed therebetween.

(E) Function and Effect With the configuration described above, the present invention has the following function and effect.

That is, in the present invention, the pressure drop effect preventing partition plate is interposed between the detection unit of the water level detection sensor and the hot water suction unit of the forced circulation path, so that the forced Even if a pressure drop occurs in the bath water suction section provided at one end of the circulation path, the presence of the pressure drop prevention partition plate causes the effect of the pressure drop in the bath water suction section to be reduced by the water level detection section of the water level detection sensor. Is never received.

Therefore, regardless of the use of forced circulation,
The water level detection sensor can accurately detect the bath water level in the bathtub body.

(F) Example Hereinafter, the present invention will be specifically described based on an example shown in the accompanying drawings.

FIG. 1 shows a conceptual configuration of a fully automatic bath kettle device A according to the present invention, except for a configuration in which a partition plate B for preventing the effect of pressure drop is attached to a bath kettle main body 4. It has the same configuration as the configuration of the fully automatic bath kettle device A described with reference to FIG.

Therefore, the components having the same functions as those of the components of the fully automatic bath kettle device A shown in FIG. 3 are denoted by the same reference numerals.

As shown in FIG. 1, in the present embodiment, the detection unit 8a of the water level detection sensor 8 is disposed at the center of the bathtub body 4.

And, inside the bath kettle main body 4, the detecting unit 8a,
A partition plate B made of a stainless steel plate or the like for preventing a pressure drop is provided at a location between the forced circulation path 6 and the bath water suction portion 6a.

Due to the presence of the pressure drop influence preventing partition plate B,
The detection unit 8a of the water level detection sensor 8 and the bath water suction unit 6a of the forced circulation path 6 are completely shut off.

Therefore, even if a pressure drop occurs in the bath water suction portion 6a provided at one end of the forced circulation path 6 as in the case of additional heating, the presence of the pressure drop influence preventing partition plate B causes the bath water suction portion 6a. The detection section 8a of the water level detection sensor 8 is not affected at all by the pressure drop at the time.

That is, as shown in FIG. 2, even if the pump 7 is turned on,
There is almost no decrease (fluctuation) in water pressure.

Therefore, regardless of whether the forced circulation path 6 is used, the water level detection sensor 8 can always accurately detect the bath water level in the bathtub main body 1 and perform accurate hot water filling operation and adding hot water operation. Become.
