Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a bubble bath device capable of supplying a jet stream containing air bubbles into a bathtub.

[Prior Art] Conventionally, there has been a bubble bath device in which an air suction mechanism is provided in a circulation channel that connects a forced circulation bath pot and a bathtub so that a jet stream containing air bubbles can be supplied to the bathtub.

[Problems that the invention aims to solve] However, in conventional bubble baths, sufficient consideration has not been given to the activation of the heating device (reheating) to raise the temperature of hot water and the switching operation between the bubble bath and the switching operation, which is troublesome. It was hot.

The purpose of this proposal is to add a reheating function to bubble baths, whose demand is expected to increase in the future, and to provide a bubble bath device that allows switching between reheating and bubble baths with a single touch.

[Means for solving the problem] In order to achieve the above object, the bubble bath device of the present invention includes a bathtub, a circulation channel for circulating hot water in the bathtub outside the bathtub and returning it back into the bathtub, and a circulation channel for circulating hot water in the bathtub to the bathtub. an air suction mechanism into the circulation flow; a heating flow path branching from the circulation flow path and joining the circulation flow path again; a heating device provided in the heating flow path; and a heating device provided in the circulation flow path. a water pump capable of switching between a strong operating state that obtains a high flow rate that allows sufficient air to be sucked from at least the air suction mechanism and a weak operating state that obtains a flow rate suitable for heating by the heating device; A configuration is adopted that includes a control device that operates the device and includes a reheating operation switch that operates the water pump in a weak manner and a bubble bath operation switch that causes the water pump to operate in a strong manner.

[Operation and Effects of the Invention] The bubble bath device of the present invention has a strong operation that allows the water pump to suck in sufficient air in the air suction mechanism, and
It has a function to switch between low-level operation, where almost no air intake occurs, and the operation of the heating device is linked during low-level operation.These can be done by operating a switch, so switching between reheating and bubble bath is possible. It's extremely easy to do.

[Effects of the Example] (a) Since the function of a forced circulation bath pot is added to the conventional bubble bath pump unit, - It can be used as a standalone bubble bath.

・Can also be used as a bath kettle.

(b) With conventional bubble baths, the water gets particularly cold during use, but by using this device, you can enjoy a bubble bath with constant water temperature.

(c) Ease of installation, space, etc. are not much different from those of conventional pump unit installations. (Compared to installing a reheating pot separately from the pump unit, it is easier to install and takes up less space.) (d) Reheating uses a pump to forcefully circulate the hot water in the bathtub, so there is no difference in temperature between the top and bottom. Also, by adjusting the water temperature, you can always maintain a constant temperature.

(E) The pump operates strongly when using a bubble bath, and operates weakly when reheating, reducing power consumption.

(F) If there is water in the bathtub, you can prevent it from freezing by using forced circulation with a pump.

A pressure valve 46 is provided upstream of the heat exchanger 22 in the heating flow path 45 and opens when the water pump 43 is operated and the pressure of water in the circulation flow path downstream of the water pump is high. . The water pump 43 is controlled by the control device and can be switched between strong operation and weak operation. When the water pump 43 is in operation, the pressure valve 46 opens, and a portion of the hot water in the circulation flow path downstream of the water pump is supplied from the pressure valve 46 to the heat exchanger, and further upstream of the water pump. The water is sucked into the circulation channel and returns to the water pump 43 again.

It should be noted that the water pump 43 may be capable of switching its capacity in three or more stages, or may be provided with a stepless capacity switching mechanism.

When the water pump 43 is operated strongly, air is sucked into the high-speed jet ejected from the outlet 42 of the circulation channel 40 by the action of the ejector 62, and the air is sucked into the hot water 10 of the bathtub 1 as a jet containing air bubbles. It becomes a bubble bath operation where the bubbles are squirted. Furthermore, when the water pump 43 is operated in a weak manner, air is not sucked in because the flow velocity of the jet jet jetted from the flow path outlet 42 is low, and a weak jet jet is jetted into the hot water 10.

The control device 5 includes a control circuit 52 housed in a control device case 51, a remote control panel 53 installed separately from the case at a predetermined location such as a bathroom, and the heating channel 45 of the circulation channel 40. A temperature sensor 50 is provided upstream of the confluence point of the circulation flow and detects the temperature of the circulating flow.

As shown in FIG. 3, the control circuit 52 includes a bubble bath switch S ₁ , a reheating switch S ₂ connected in parallel to the switch S ₁ , and a switch S 3 that is linked to the switch S ₁ and operates the water pump ₄₃ at high speed. , said Switch S ₂

R ₁ , the water pump 4 is connected in series with the switch S ₃
3, a relay R ₂ for switching between strong operation and weak operation, and a power source V. Said switches S ₁ and S ₂
are opened (OFF) and closed (ON) by pressing a bubble bath button 54 and a reheating button 55 provided on the operation panel 53, respectively. A bubble bath lamp and a combustion (display) lamp (not shown) are incorporated in these buttons 54 and 55, and are turned on when the respective buttons are pressed and the switches _S1 and _S2 are closed. Switches S ₁ , S ₂ , S ₃ and S ₄ are all OFF during steady state.
, and contact r ₁ of relay R ₁ connected in series to motor M of water pump 43 is open (OFF).
A contact r ₂ of a relay R ₂ connected in series with the contact r ₁ is connected to a weak operation gate P ₂ . bubble bath button 5
When 4 is pressed, switches S ₁ and S ₃ are closed, relays R ₁ and R ₂ are energized, contact r ₁ is closed, switching contact r ₂ is switched from connection to strong operation P ₁ , and the water pump is switched on. 43 is driven hard. As a result, a jet stream 64 containing bubbles is ejected from the ejector 62 into the hot water 10 as shown in FIG. 1, and a bubble bath operation is achieved. Switches S ₁ and S ₃ are opened by pressing the bubble bath button 54 again or by pressing the reheat button 55 to return to the steady state. Reheat button 55
When is pressed, switches S ₂ and S ₄ are closed, which energizes relay R ₁ and closes contact r ₁ , causing the water pump 43 to run at low speed and turning on the heating device 3.
The main gas burner 31 is ignited. As a result, as shown in FIG. 2, the hot water flowing through the heat exchanger 22 is heated by the heat generated by the combustion flame 3A of the main burner, and the heated hot water is sucked into the water pump 43 and is drawn into the flow path outlet of the circulation flow path 40. 42 as a weak jet 65 and is supplied into the hot water 10 of the bathtub, thereby achieving forced circulation heating reheating operation.
