Description

[Detailed description of the invention] "Industrial application field" This invention is a so-called bathtub separate type bathtub, in which the bathtub and the bathtub are separated, and the two are connected by a bathtub water introduction passage and a heated water return passage. Concerning improvements to equipment.

``Prior Art'' In this type of bathtub device with separate bathtub, the introduction passageway that leads bathtub water from the bathtub into the bathtub is connected to the heated water return passageway that returns hot water heated in the bathtub into the bathtub. Because it is located at the bottom, and because heated hot water has the property of floating upwards, heated hot water always stays at the top of the bathtub.

For this reason, it has conventionally been necessary for households using the above-mentioned bathtubs to stir the bathtub using a stirring rod when taking a bath or before taking a bath.

``The problem that the invention attempts to solve'' However, in this type of bathtub, people often forget to stir,
Or, people often take a bath by checking the temperature of the hot water only in the surface layer before stirring is sufficient, and because of this, bathing in hot water with a temperature difference between the surface layer and the bottom layer can cause people to catch a cold, especially in the winter. In addition, it has sometimes caused heart failure in sick and elderly people.

In addition, even when stirring is performed, if the mixture is stirred by hand without using a stirring rod, burns may occur if the hot water at the surface layer is at a high temperature.

Furthermore, when heating hot water during bathing, high-temperature water is discharged into the bathtub from the heated water return passage,
The high-temperature water may cause burns.

The technical problem to be solved by the present invention is to automatically stir the hot water in the bathtub without using the above-mentioned stirring rod etc., so that the heated water does not separate into the upper layer and the lower layer, and is uniform throughout the entire layer. The purpose of the present invention is to provide a bathtub device with a separate bathtub that can be stirred.

The purpose of the present invention is to add bath water to hot water heated from a bath pot, and mix and stir the two before returning to the bathtub.As a result, there is no risk of burns during bathing, and the water is uniform. To provide a bathtub device with a separate bathtub that further enables stirring.

A further object of the present invention is to provide a bathtub device with a separate bathtub that can also be used as a shower by being configured so that a shower can be attached to the opening on the bathtub side of the heated water return passage.

"Means for solving problems" In order to achieve such technical problems, this invention
For example, as shown in FIG. 1, in a separate bathtub device in which a bathtub 1 and a bathtub 2 are separated, and both 1 and 2 are connected by a bathtub water introduction passage 3 and a heated water return passage 4, Warming water return passage 4 from the bathtub water introduction passage 3 without passing through the bathtub 1
A fan 6 which is connected to a motor 61 and whose rotation speed can be controlled is disposed in the heated water return passage 4 on the downstream side of the outlet end of the bypass passage 5. We propose a technical means configured such that heated water in a bathtub 1 and bathwater returned from a bypass passage 5 can be mixed and discharged into a bathtub 2 by forced water feeding power.

In this case, the bypass passage 5 as shown in FIG.
may be formed by an independent pipe inserted into the bathtub water introduction passage 3, or may be formed by simply branching the bathwater introduction passage 3 and opening into the heated water return passage 4. .

"Operation" According to this technical means, together with the high-temperature heated water heated in the bath pot 1 by the fan 6, unheated bath water is sucked from the bypass passage 5 and mixed and stirred. The temperature is lowered to an appropriate temperature, and the mixed heated water is forcibly sent into the bathtub 2.
The water in the bathtub 2 is mixed with the heated water while being forcibly stirred by convection by the sending force.

Therefore, there is no need for manual stirring as in the prior art, and fluid stirring is performed automatically, and the high-temperature heated water flowing in the bathtub water introduction passage 3 is sucked from the bypass passage 5. Since the heated water is mixed and stirred and lowered to a temperature that does not cause burns, it is forcibly sent into the bathtub 2, so there is no risk of burns even if the bath is heated during bathing.

Furthermore, since the heated water is sent into the bathtub 2 at a predetermined flow rate by the fan 6, and since the heated water sent out from the outlet end 41 of the heated water return passage 4 is lowered to an appropriate temperature, By attaching a shower mechanism 7 to the outlet end 41, it can also be used as a shower.

It is more preferable that the fan 6 is configured with a propeller fan 62 because it can provide a more sufficient stirring function.

Further, the fan 6 is provided with a rotation speed adjustment switch 63.
By attaching a control mechanism that can control the amount of water fed, for example, it is possible to increase the amount of water fed when used as a shower, or to reduce the amount of water fed when used to warm bath water.

Furthermore, even in the case of heating the bathtub water, if the heated water heated in the bathtub 1 in conjunction with the temperature sensor 81 is high temperature, the water is sucked from the bypass passage 5 by increasing the amount of water fed. It is possible to increase the amount of water mixed with the bathtub water and to prevent high-temperature heated water from being sent into the bathtub 2.

Furthermore, a temperature sensor 82 is arranged on the bathtub water introduction passage 3 or bypass passage 5 side, and the temperature sensor 8
Based on the signal from 2, the heating in bath pot 1 is turned on.
By configuring the fan 6 to perform ON-OFF control as well as -OFF, it is possible to prevent over-boiling and automatically adjust the temperature.
