Method for introducing cold foam into a shower cubicle, a vapor bath or another sanitary facility suited for this, and device for such a method
The method includes the introduction of foam into a shower cubicle, a vapor bath, or another sanitary facility. The foam is introduced at a temperature of −15° C. to 20° C., preferably of 0° C. to 18° C., particularly preferred of 5° C. to 15° C., from a foam generator into the shower cubicle, the vapor bath, or the other sanitary facility. The foam preferably has the temperature at an outlet of the foam generator. Apart from that, the disclosure also relates to a device for such a method according to the disclosure and a shower cubicle or a vapor bath having such a device.
1 . A method for introducing foam into a shower cubicle, a vapor bath, or another sanitary facility, the method comprising the steps of:
lowering a freezing point of liquid water to below 0° C. by admixing a component into the liquid water;
supplying the liquid water from a cold water reservoir to an inlet of a foam generator, the cold water reservoir including a cooling means that sets the liquid water at a temperature that is below 0° C.,
supplying soap via a soap inlet and admixing the soap to the liquid water before entering the foam generator,
producing foam by blowing air into a mixture of soap and liquid water at a temperature of −18° C. to below 0° C., and
introducing the foam into the shower cubicle, the vapor bath, or the other sanitary facility through an outlet of the foam generator, wherein the foam has a temperature of −15° C. to 20° C. at the outlet.
2 . The method according to claim 1 , further comprising the step of:
supplying the air via a fan to exit from a bubble plate at the bottom of the foam generator.
3 . The method according to claim 1 , further comprising the step of:
controlling a surface level of the mixture of liquid water and soap in the foam generator by a controlled supply of liquid water and soap.
4 . The method according to claim 1 , further comprising the step of:
adding at least one of a disinfectant and a scent to the liquid water downstream of the cold water reservoir and upstream of the foam generator.
5 . The method according to claim 4 , wherein the disinfectant comprises hydrogen peroxide.
6 . A method of introducing foam into a sanitary facility, the method comprising:
lowering a freezing point of liquid water to below 0° C. by admixing a component into the liquid water;
cooling the liquid water in a cold water reservoir with a cooling means that sets the liquid water at a temperature that is below 0° C.;
supplying the liquid water from the cold water reservoir and soap to an inlet of a foam generator,
producing foam by blowing air through a bubble plate disposed within the foam generator into a mixture of the soap and the liquid water, the mixture of soap and liquid water being at a temperature of −18° C. to below 0° C., and
introducing the foam into the sanitary facility through an outlet of the foam generator,
wherein the temperature of the foam when introduced into the sanitary facility is between −15° C. and 20° C.
7 . The method of claim 6 , comprising:
supplying warm water at a temperature between 30° C. and 60° C. to the inlet of the foam generator, and
controlling a temperature of the water supplied to the inlet of the foam generator via a control valve coupled to the cold water supply and the warm water supply.
8 . The method of claim 6 , wherein at least one of a disinfectant and a scent is added to the supplied water before entering the inlet of the foam generator.
9 . A method of introducing foam into a sanitary facility, the method comprising:
lowering a freezing point of liquid water in a cold water supply to below 0° C. by admixing a component into the liquid water,
cooling a temperature of the liquid water in the cold water supply to below 0° C.,
providing cold water at a temperature that is below 0° C. from the cold water supply to an inlet of the foam generator,
providing warm water at a temperature between 30° C. and 60° C. from a warm water supply to the inlet of the foam generator,
controlling a temperature of the water supplied to the inlet of the foam generator via a control valve coupled to the cold water supply and the warm water supply such that the temperature of the liquid water in the foam generator is in the range of −18° C. to below 0° C.,
supplying air into a mixture of soap and the water that has a temperature in the range of −18° C. to below 0° C. in the foam generator to generate foam, and
introducing the foam into the sanitary facility through an outlet of the foam generator.
10 . The method of claim 9 , comprising the steps of:
draining the foam generator of the mixture of water and soap through a drain of the foam generator, the drain being connected to a mixed water reservoir, and
supplying the foam generator with the mixture of water and soap from the mixed water reservoir through a control valve such that the mixture of water and soap is selectively supplied from the mixed water reservoir again to the foam generator.
