DETAILED DESCRIPTION OF THE INVENTION
In order to illustrate the present invention more specifically, some examples will be described below with reference to the accompanying drawings.
[0015]
[Example 1]
Examples of bathroom hot air generating device according to the present invention, FIGS. 1, 2, 3, 4, will be described based on the FIG.
1 is an outer case of the apparatus of the present embodiment, and on the front, a hot air outlet 2, an air suction port 3, a hot water inlet 4 for connecting the tip of a hose ( not shown ) extending from a hot water faucet, A drain port 5 for discharging used hot water to the outside of the apparatus, an opening / closing handle 6 for the heat exchange valve 14, and an opening / closing handle 7 for the spray valve 17 are arranged.
[0016]
Hot water flowing in from the hot water inlet 4 enters the water turbine chamber 8 and rotates the water wheel 9.
The water turbine 9 shares the rotating shaft 11 with the sirocco fan 10, and drives the sirocco fan 10 as the water turbine 9 rotates, so that the air flow from the air suction port 3 toward the hot air outlet 2 is generated in the apparatus. To generate.
The hot water leaving the water turbine chamber 8 passes through the water guide pipe 12 and reaches the bifurcated branch pipe 13.
One outlet of the bifurcated branch pipe 13 is connected to the inlet of the induction pipe 16 of the radiator type heat exchanger 15 through a heat exchange valve 14.
The other outlet of the bifurcated branch pipe 13 is connected to the inlet of the sprayer 18 via the spray valve 17.
[0017]
The heat exchanger 15 is constituted by a number of thin plate highly thermally conductive fins 19 fixed with the induction pipe 16 into the induction pipe 16 for guiding the hot water.
Hot water that has passed through the induction pipe 16 is discharged from the drain port 5 to the outside of the apparatus.
The sprayer 18 includes a chamber 20 and a plurality of spray ports 21 provided on the bottom surface of the chamber.
The hot water that has entered the chamber 20 through the spray valve 17 accumulates in the chamber 20 and increases the internal pressure.
When the pressure becomes a certain level or more, it is atomized from the spray port 21 and blown out into the entrance of the fan cover 22 that covers the sirocco fan 10.
[0018]
In this way, the hot water that has entered from the hot water inlet 4 rotates the sirocco fan 10 to generate an airflow in a certain direction in the apparatus.
At the same time, by passing through the heat exchanger 15, heat is given to the air flow to warm it.
Moreover, the hot water that has entered the sprayer 18 is sprayed into the airflow to increase the humidity of the airflow.
The strength of the airflow depends on the amount of hot water per unit time passing through the water turbine chamber 8.
Since this flow rate is substantially equal to the flow rate to the heat exchanger 15 which is the main hot water flow, it can be adjusted by the degree of opening of the heat exchange valve 14 for adjusting the flow rate.
That is, the amount of hot air and the wind speed can be adjusted by rotating the handle (6). Moreover, since the humidity of the airflow is determined by the amount of hot water supplied to the sprayer 18, it can be adjusted by the handle 17 that adjusts the spray valve 17.
In addition, since the flow pressure remains in the hot water discharged | emitted from the drain port 5, if it is a little height, it can be induced | guided | derived with a hose.
[0019]
[Example 2]
The second embodiment, without using the heat exchanger 15 as described above in Example 1, in which it was decided by spraying by nebulizer 18.
Specifically, the water turbine chamber 8 and the spray valve 32 are directly connected to the entrance of the sprayer 33 through the water guide pipe 12.
In this way, the entire amount of hot water supplied to the apparatus is supplied to the sprayer 33.
The sprayer 33 is provided with a larger number of spray ports ( not shown ) than that of the first embodiment, and a sirocco fan is provided with an amount of hot water that can obtain a water flow enough to ensure sufficient rotation of the water wheel 9. 10 is blown out into the entrance of the fan cover 34 that covers 10.
The lower side of the entrance side of the fan cover 34 is a bowl- shaped hot water receptacle 35.
In this way, the hot water sprayed from the sprayer 33 gives moisture to the airflow, and the hot water that has not flown with the airflow is received and guided by the hot water receiver 35 and discharged from the drain port 5 to the outside. It is.
Reference numeral 36 denotes an air suction port for sucking outside air into the outer case 31. Since other configurations are the same as those of the first embodiment, the same reference numerals are given in the drawing, and description thereof is omitted here.
[0020]
[Example 3]
In the configuration as in the second embodiment, since there is no fluid pressure in the hot water after use, there is a case where the hot water has to be abandoned when the apparatus is arranged at a low position.
For this reason, in the present Example, the structure which gives a flow pressure to such hot water was employ | adopted.
Specifically, the rotary shaft of the rotary pump 41 is connected to the other rotary shaft 11 of the water wheel 9.
The inlet 42 of the rotary pump 41 is connected to the tip of an extended drain pipe 43 that extends the drain port 5.
In this manner, the rotary pump 41 is driven together with the sirocco fan 10 by the fluid pressure of the hot water to apply pressure to the hot water to be discharged, so that the hot water after use can be used without waste.
[0021]
[Other Examples]
In each of the above embodiments, the heat exchange structure is arranged on the air suction port side of the fan. However, it can be arranged on the air discharge port side.
When a radiator type heat exchanger is used as in the first embodiment, the baffle fan may be driven by hot water that has passed through the heat exchanger.
【The invention's effect】
In short, in the present invention, the flow of warm air can be created in the bathroom only by using the hot water supply equipment that is usually present in the bathroom.
Therefore, the bathroom can be made into a hot and humid atmosphere like a sauna without requiring any incidental work such as electrical work in use.
Furthermore, since the required fluid pressure can be applied also to the hot water after use, its use is easy.
