Description

The present invention relates to a bathroom sterilizer for sterilizing the inside of a bathroom by spraying ozonized water in which ozone is dissolved into the bathroom.

The humidity in the bathroom is high, and organic matter such as soap scum often adheres to the walls of the bathroom, making it easy for mold and germs to grow. For this reason, wall surfaces tend to grow mold and the like unless they are frequently disinfected and cleaned.

On the other hand, ozonized water in which ozone is dissolved is known to have high sterilizing power, and it is known to use ozonated water for the purpose of sterilizing air (see, for example, Patent Document 1). From this, it is conceivable to spray ozonated water from a nozzle into the bathroom to sterilize the walls of the bathroom and the air in the bathroom with the ozonized water to suppress the growth of mold and germs.

Japanese Patent Application Laid-Open No. 2002-282346 (Claim 1)

In the sterilization using ozone water, the toxicity of ozone water is less likely to remain after the ozone water is sprayed, so it is preferable to use ozone water for sterilization of bathrooms. However, since it is not preferable that the ozonized water itself is sprayed directly onto the human body, the start switch of the bathroom sterilizer that sprays the ozonized water into the bathroom must be provided outside the bathroom. However, if the start switch is provided outside the bathroom, it is conceivable that the start switch may be inadvertently pressed when someone is in the bathroom. Then, the person in the bathroom will be sprayed with ozone water, and such a state is not preferable as described above.

If the concentration of ozonized water is kept low, the effect on the human body can be reduced even if the start switch is accidentally pressed while there are people in the bathroom, but that would reduce the sterilization power in the bathroom. decrease and the bactericidal effect cannot be exhibited. Therefore, it is necessary to spray ozonated water with a concentration that affects the human body in the bathroom.

Therefore, in view of the above problems, the present invention maintains the sterilization effect in the bathroom and reduces the influence on the human body as much as possible even if the start switch is accidentally pressed while people are in the bathroom. An object of the present invention is to provide a bathroom sterilizer that can

In order to solve the above problems, the bathroom sterilizer according to the present invention is a bathroom sterilizer that sprays ozonized water from a nozzle into a bathroom to sterilize the inside of the bathroom. fresh water and the nozzle are alternately sprayed , and the nozzle is formed around the bottom of a cylindrical body with a bottom that is movable in the vertical direction so as to communicate with the inner space of the cylindrical body. a housing position where the nozzle is hidden by an urging force that urges the tubular body upward; It is characterized in that the nozzle is movably provided at an ejection position where the nozzle is exposed .

If the ozonized water with a concentration that can exhibit a sterilizing effect on the inside of the bathroom is continuously sprayed, if a person is in the bathroom by mistake, the ozonated water with that concentration will be sprayed on the human body. However, even if the ozonized water is sprayed on the human body, the effect on the human body can be suppressed as much as possible by spraying fresh water from the nozzle afterward to wash away the ozonized water sprayed on the human body.

If there is no one in the bathroom, there is no need to spray fresh water. Therefore, the state in which ozonated water and fresh water are alternately sprayed from the nozzle is changed to a continuous mode in which only ozonated water is sprayed continuously. A switchable configuration is desirable.

In particular, when sterilizing by continuously spraying ozonized water, there are cases where there is a demand for increasing the ozone concentration of the ozonated water in order to further enhance the sterilizing effect. In such a case, it is desirable to switch the concentration of ozone dissolved in the ozone water.

When sterilization with ozone water is completed, the sprayed ozone water is drained out of the bathroom through the drain port. However, the ozone gas liberated from the ozone water will remain in the bathroom. Therefore, it is desirable that the bathroom is equipped with a ventilation fan, and that the ventilation fan is forced to operate after the sterilization of the bathroom with the ozone water is finished.

In addition, a forced stop switch is provided in case the spraying of the ozonated water is started by mistake while someone is in the bathroom. When the forced stop switch is pressed, the spraying of the ozonized water is stopped. , it is desirable to forcibly operate the ventilation fan.

As is clear from the above description, the present invention secures the sterilizing effect in the bathroom by spraying ozonized water with a concentration that has a sterilizing effect into the bathroom, and at the same time, when the ozonized water is sprayed, an erroneous If a person is in the bathroom, the ozonized water sprayed on the human body can be washed away with fresh water to minimize the effects of the ozonized water on the human body.

Referring to FIG. 1, 1 is a bathroom, and a bathroom remote control 11 is provided on the wall surface. A ventilation fan 2 is provided on the ceiling, and when the ventilation fan 2 operates, the air in the bathroom 1 is exhausted to the outside through an exhaust duct 21.例文帳に追加Further, nozzles 3 for spraying fresh water supplied from a water pipe 5 and ozonated water supplied from an ozonated water generator 6 into the bathroom 1 are provided on the ceiling surface.

An electromagnetic switching valve 4 is connected to the nozzle 3 . The switching valve 4 has a valve closing function, and can be switched so that fresh water from the water pipe 5 and ozonated water from the ozonized water generator 6 are alternatively supplied to the nozzle 3 .

The ozone water generator 6 is provided with two ozone gas generators 61 and 62. Normally, the ozone gas generator 61 operates, and a signal from the outside activates the ozone gas generator 62 to generate both ozone gases. The generators 61 and 62 are configured to operate simultaneously. The ozone gas generated by both the ozone gas generators 61 and 62 is sent to the gas-liquid mixer 63 . A branch pipe 51 branched from the water pipe 5 is connected to the gas-liquid mixing unit 63 , and ozone gas is dissolved in fresh water supplied from the water pipe 5 through the branch pipe 51 . is supplied to the switching valve 4.

Referring to FIG. 2, 7 is a remote controller installed in a place other than the bathroom 1, for example, in the kitchen. In this embodiment, a kitchen remote controller provided in the kitchen is shown. The kitchen remote controller 7 is provided with various switches for sterilizing the inside of the bathroom 1 in addition to various switches for controlling the water heater (not shown). As a switch for these sterilizations, a sterilization switch 71 for starting sterilization is provided. When the sterilization switch 71 is pressed, fresh water and ozone water are alternately sprayed from the nozzle 3 . In addition, a continuous sterilization switch 72 is provided, and when the sterilization switch 71 is pushed and sterilization is started, that is, in a state where fresh water and ozone water are alternately sprayed from the nozzle 3, this continuous sterilization switch 72 is operated. When the sterilization switch 72 is pushed, the switching valve 4 is fixed in a state in which the ozonized water is supplied to the nozzle 3, and only the ozonized water is sprayed from the nozzle 3 continuously.

While the ozonized water is being continuously sprayed, only the ozone gas generator 61 operates, and the other ozone gas generator 62 does not operate. When the continuous sterilization switch 72 is pressed again in this state, that is, in a state where the ozone gas generator 61 is operating alone, the LED lamp 72a lights up, the ozone gas generator 62 starts operating, and the nozzle 3 The ozone concentration of the sprayed ozone water increases. When the sterilization switch 71 is pushed to start sterilization with ozone water, the sterilization with ozone water is automatically stopped after a certain period of time has passed since the start. However, a sterilization stop switch 73 is provided to forcibly stop sterilization on the way. A switch having the same function as the sterilization stop switch 73 is also provided in the bath remote controller 11 .

The sterilization operation using the ozone water described above will be described in further detail with reference to the flowchart of FIG. When the sterilization switch 71 is pushed, the internal timer starts counting down (S1, S2), the switching valve 4 starts switching operation, and fresh water and ozone water are alternately sprayed from the nozzle 3. A switching operation is started (S3).

In this state, it is monitored whether or not the continuous sterilization switch 72 is pushed, and if the continuous sterilization switch 72 is not pushed before the timer finishes counting down (S5), the switching valve 4 is operated. , only fresh water is continuously sprayed from the nozzle 3 (S6), and the ventilation fan 2 is operated to exhaust the air in the bathroom 1 (S7). After fresh water is sprayed and ventilation is performed for a certain period of time, the switching valve 4 is closed and the ventilation fan 2 is stopped (S8) to return to the standby state.

When the continuous sterilization switch 72 is pushed before the timer finishes counting down, the switching valve 4 is fixed to the state in which only the ozone water is supplied to the nozzle 3 as described above, and continuous operation is started. (S9). In this state, only the ozone gas generator 61 operates alone as described above, but if the continuous sterilization switch 72 is pressed again before the timer finishes counting down, the ozone gas generator 62 starts operating. Then, the ozone concentration of the ozone water sprayed from the nozzle 3 is increased (S10, S11). When the countdown of the timer ends, the process proceeds to S6 described above, where fresh water is continuously sprayed from the nozzle 3 to wash away the ozone water remaining on the inner wall of the bathroom 1, and the ozone gas remaining in the space inside the bathroom 1 is washed away. is exhausted, the system returns to the standby state (S12, S6, S7, S8).

During the sterilization operation using the ozone water, it is constantly monitored whether the sterilization stop switch 73 is pressed (S13). , immediately proceeds to S6, sprays fresh water and performs ventilation, and is controlled to return to the standby state.

By the way, the nozzle 3 needs to protrude downward to some extent from the ceiling surface of the bathroom 1 so that the sprayed ozone water adheres to the ceiling surface of the bathroom 1 as well. However, if it remains in a protruding state, it looks bad in terms of design. Therefore, as shown in FIG. 4, for example, when the water pressure of fresh water or ozone water acts, the piston 31 in the cylinder 32 moves downward against the upward biasing force of the spring 34, and the bottom of the piston 31 moves downward. It may be configured such that it protrudes from the base 33 and sprays fresh water or ozonized water from a nozzle port provided in the protruding portion.

With the above configuration, when the switching valve 4 is closed, the pressure in the cylinder 32 decreases, so the biasing force of the spring 34 pushes up the piston 31 and the lower portion of the piston 31 is stored in the base 33 . A plurality of nozzle ports are provided in the lower part of the piston 31. In order to allow the ozonized water to reach the wall surface of the outer periphery of the lower part, a nozzle port with a relatively large opening diameter is provided. It is desirable to provide a nozzle port with a relatively small opening diameter so that the ozonated water can be sprayed in the form of a mist so that the ozonated water can float for a long time. In addition, 12 is the ceiling of the bathroom 1 .

It should be noted that the present invention is not limited to the embodiments described above, and various modifications may be made without departing from the gist of the present invention.
