Description

Technical Field

[0001] The present invention relates to the technical field of water heaters, and in particular to a water heater, a hot air drying component, a bathing system and a control method and a control device thereof. Background Art

[0002] Common types of water heaters include electric water heaters and gas water heaters. The working principle of electric water heaters is to use heating pipes to supply electricity for heating. Electric water heaters are divided into two categories: storage electric water heaters and instant electric water heaters. Storage electric water heaters are more popular. They are relatively simple to install and can supply water in multiple ways, but they need to be preheated before use, and the amount of stored hot water has a rated capacity, which is inconvenient for families with a large population and a large demand for hot water. Instant electric water heaters heat up as soon as they are turned on, and the water temperature is constant, but they must be powered on all the time, which poses certain safety hazards in electricity use. The capacity of an electric water heater is directly related to the volume of the product. Generally speaking, the volume is relatively large and occupies space. Its working principle is to use heating pipes to supply electricity for heating. Electric water heaters in related technologies use heating pipes to supply electricity for heating. After long-term use, scale will adhere to the heating pipes, which will cause poor local heat dissipation of the heating pipes and even burn the heating pipes, posing an unsafe problem.

[0072] Common types of water heaters include electric water heaters and gas water heaters. The working principle of electric water heaters is to use heating pipes to supply electricity for heating. Electric water heaters are divided into two categories: storage electric water heaters and instant electric water heaters. Storage electric water heaters are more popular. They are relatively simple to install and can supply water in multiple ways, but they need to be preheated before use, and the amount of stored hot water has a rated capacity, which is inconvenient for families with a large population and a large demand for hot water. Instant electric water heaters heat up immediately after turning on, and the water temperature is constant, but they must be powered on all the time, which poses certain safety hazards in electricity use. The capacity of an electric water heater is directly related to the volume of the product. Generally speaking, the volume is relatively large and occupies space. Its working principle is to use heating pipes to supply electricity for heating. Electric water heaters in related technologies use heating pipes to supply electricity for heating. After long-term use, scale will adhere to the heating pipes, which will cause poor local heat dissipation of the heating pipes, and even burn the heating pipes, which poses an unsafe problem. When the user's water consumption is large, hot water cannot be provided quickly, and the user needs to wait.

[0073] In addition, when the user finishes showering, there are often many water droplets remaining on the body and hair, which need to be wiped dry manually, causing inconvenience to the user.

[0074] Combine the following Figures 1 to 4 , describing an embodiment of the present invention.

The glass tube will not produce a galvanic cell reaction and is not easy to scale. In addition, the surface volume of the glass cover 202 is large and the heat transfer is fast. The infrared heating device 2 generates far-infrared radiation during the heating process, which can denature the protein tissue of microorganisms including bacteria and viruses in the water, achieving a sterilization effect. In addition, infrared rays can directly act on hydrogen bonds to convert large molecular water into small molecular water, which is beneficial to the human body and improves the water quality.
