A kind of automatic cold insulation shower curtain

Abstract

The invention discloses an automatic cold insulation shower curtain. The automatic cold insulation shower curtain comprises a water inlet pipe, a water distribution switch, a shower head, four groups of liquid distribution devices and a water discharging system. The four groups of liquid distribution devices are arranged peripherally to form a shower space, the water inlet pipe and the water distribution switch are positioned above the shower space, and the shower head is positioned in the shower space. A water outlet of the water inlet pipe is connected with a water inlet of the water distribution switch, a shower water outlet of the water distribution switch is connected with the shower head, and a water distribution outlet of the water distribution switch is respectively connected with the four groups of liquid distribution devices. The water discharging system is connected with the liquid distribution devices. The automatic cold insulation shower curtain has an automatic expansion and retraction function and has advantages that hot water circuits are effectively used and distributed to provide a cold insulation function, radiant heat loss of a human body can be effectively reduced during showering, and accordingly comfort is improved; in addition, due to pure mechanical control without power equipment, safety and reliability are guaranteed.

Description

technical field [0001] The invention belongs to the field of radiation heat transfer, and in particular relates to an automatic cold-insulation shower curtain. Background technique [0002] At present, electric lamps or electric hot air are mainly used to keep the bathroom warm in winter. These two methods not only consume a lot of power, but also because the indoor wall temperature is low in winter, the radiation heat exchange between the human body and the wall is still large, resulting in a sense of comfort for the human body. decline. Especially for cold winter and hot summer areas, there is no central heating and other problems, causing the average temperature of the bathroom wall to be generally lower than ten degrees Celsius. Since the temperature of the human body generally remains above thirty-five degrees Celsius, a problem will arise: the human body (>35°C) and the wall (10°C<) due to the radiation heat transfer caused by the large temperature difference, a...

Problems solved by technology

[0002] At present, electric lamps or electric hot air are mainly used to keep the bathroom warm in winter. These two methods not only consume a lot of power, but also because the indoor wall temperature is low in winter, the radiation heat exchange between the human body and the wall is still large, resulting in a sense of comfort for the human body. decline

Especially for cold winter and hot summer areas, there is no central heating and other problems, causing the average temperature of the bathroom wall to be generally lower than ten degrees Celsius. Since the temperature of the human body generally remains above thirty-five degrees Celsius, a problem will arise: the human body (>35°C) and the wall (10°C<) due to the radiation heat transfer caused by the large temperature difference, and the heat radiation intensity has a fourth power relationship with the temperature, which causes the human body to produce a relatively large temperature difference between the bathroom wall. Large heat flux density, and this heat transfer is evenly distributed on the surface of the human body, making people feel very uncomfortable when taking a bath

After taking a bath, since the evaporation of water on the surface of the human body takes away a large amount of latent heat, this uncomfortable cold feeling will be aggravated, and it is easy to cause a cold, which reduces people's quality of life

[0003] In order to overcome the discomfort caused by the cold radiation of the wall when taking a bath, people usually spray hot water on the bathroom wall to increase the temperature of the wall and reduce the radiation heat transfer, but because the temperature of the inner and outer walls of the wall is lower , it is difficult for the sprayed water to effectively increase the temperature of the wall, causing the actual effect to be even less obvious

When taking a bath, because hot water is not needed for a short period of time when using shower gel or soap, and because it feels colder when the hot water is turned off, people often turn on the hot water to provide a certain heat preservation effect, causing great harm. What a waste! On the other hand, for domestic water heaters, especially gas water heaters, cold water needs to be put in for a long time at the beginning to make the water temperature reach the temperature required for bathing, resulting in waste of water resources and heat energy
