Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a bath device having a bubble bath function and an additional heating function.

(Prior Art) A conventional bath device is known in which the suction port of a bathtub and an ejection nozzle are connected by a circulation path having a pump, and the ejection nozzle ejects jets and bubbles into the bathtub to perform body massage. It is.

(Problem that the invention aims to solve) However, since the above-mentioned bathtub water does not have a reheating function, the temperature of the bathtub water decreases with operating time, and especially when blowing out bubbles, external cooled air is supplied. The water temperature has dropped significantly. For this reason, conventional methods have been to pour hot water into the bathtub from a water heater, or to connect a separate heat source device to the bathtub for reheating. However, with the former method, the amount of hot water in the bathtub increases unnecessarily, and with the latter method, a new connection port must be opened in the bathtub, making the piping complicated and difficult to install.

(Means for solving the problem) In order to solve this problem, the present invention connects the suction port of the bathtub and the jet nozzles provided on the back and foot sides of the bathtub through a circulation path equipped with a pump. A valve for preventing backflow is provided in each of the branch discharge passages leading to the two jet nozzles on the discharge side of the pump,
A configuration in which the inlet waterway of a forced circulation heat source device with a built-in pump is connected to the upstream side of a valve interposed in one of the branched discharge passages, and the outlet waterway is connected to the downstream side of the valve of both branched discharge passages via an on-off valve, respectively. It is said that

(Function) In the bubble bath, bath water is sent from the suction port to the jet nozzle by driving the pump, and bubbles and jets are supplied from the jet nozzle into the bathtub. When performing reheating, by operating the forced circulation heat source device, the bath water is sent to the heat exchanger via the circulation path by the drive of the built-in pump, and after being heated, it is passed through the on-off valve and the branch discharge path. (Example) Fig. 1 shows an embodiment of the present invention, in which 1 is a bathtub, 2 is a suction port, and 3 is provided on opposite side walls in the longitudinal direction of the bathtub 1. The jet nozzle 3 is connected to an air pipe (not shown), sucks air with negative pressure generated by the jetting of bathtub water, and supplies it into the bathtub 1 as bubbles together with the bathtub water. Note that 3a indicates a dorsal nozzle, and 3b indicates a foot nozzle. 4 is a pump, 5 is a circulation path, and 6 is a branch discharge path 5 connected from the pump 4 discharge side of the circulation path 5 to both nozzles 3a, 3b.
This is a check valve that prevents backflow to the pump 4 side, which is provided in each of a and 5b, and an on-off valve or a three-way valve may be used. Reference numeral 7 is a forced circulation type heat source device, which uses a built-in pump to forcefully feed water to be heated to a heat exchanger heated by a gas burner, etc., and its inlet channel 7a is connected to the check valve 6 of the former branch discharge channel 5b. The outlet waterway 7b is connected to the downstream side of the check valve 6 of both branch discharge passages 5a, 5b via on-off valves 8, 9.

In the above configuration, the bubble bath is performed by driving the pump 4, and when reheating is performed, the on-off valves 8 and 9 are opened and the forced circulation heat source device 7 is operated. Then, the built-in pump drives the bathtub water to the branch discharge path 5b.
The bathtub water is sent to the heat exchanger via the inlet channel 7a, and the bathtub water heated by the heat exchanger is sent to the branch discharge channels 5a and 5b via the outlet channel 7b, and then returns to the bathtub 1 to adjust the bathtub water temperature. It is raised from Incidentally, such reheating may be performed independently or simultaneously with the bubble bath. Also, if you want to warm up from both sides of the back and legs when reheating, use the double opening/closing valve 8,
9 and when heating only from the foot side, it is sufficient to close the on-off valve 9, and in this way, the hot water discharge direction can be arbitrarily selected. Note that the on-off valve 8 may be provided in parallel with the on-off valve 9.

(Effects of the invention) As described above, in this invention, the inlet channel of the forced circulation heat source device with a built-in pump is connected to the check valve on the upstream side of the check valve installed in the branch discharge path leading to the jet nozzle. Since the outlet waterway is connected to the downstream side of the bubble bath, there is no need to unnecessarily increase the amount of water in the bathtub, and there is no need for separate piping to the bathtub, making it possible to easily add a reheating function to a conventional bath device that has a bubble bath function. Not only can bubble bath and reheating be operated simultaneously, but reheating can also be performed with the pump in the circulation path, that is, the bubble bath pump, stopped. Low reheating operation is also possible.

Furthermore, in the present invention, the outlet channel of the forced circulation heat source device is connected to both branch discharge channels via on-off valves, so the direction of discharge of reheated bath water can be directed to both the back and/or the feet. Therefore, for example, when not bathing, the water can be discharged from both the back and legs to uniformly raise the temperature of the entire bathtub, or when bathing, the water can be discharged only from the feet to prevent the risk of burns. It becomes possible to raise the temperature, and it is possible to provide a bath device that is easy to use.
