Description
Technical Field
[0001] This utility model belongs to the technical field of bathroom drying cabinets, and in particular relates to a water bath drying cabinet for bathrooms. Background Technology
[0002] Towels, as an essential item for daily bathing and face washing, are directly related to the health of users. Especially in the bathroom environment of homes and hotels, used towels are usually damp and carry organic matter such as human skin flakes, oils, and soap scum. If they are not dried in time, they can easily breed a lot of bacteria, which can harm human health.
[0003] Currently, the main methods for drying textiles such as towels and bath towels that come into direct contact with the skin in homes and hotels include: natural hanging, sun drying, clothes dryers, and electric towel racks. Effective sterilization usually requires maintaining the material within a suitable and stable temperature range for a certain period of time (e.g., 55℃-65℃). Natural hanging and sun drying are mainly affected by ambient temperature and weather, and the long time required leads to low efficiency and the inability to prevent the growth of bacteria and mold in time. Clothes dryers are not economical to start with a small number of towels at a time, and they cannot be used immediately after bathing, requiring collection and centralized washing and drying, which is a cumbersome process. Although electric towel racks can keep towels warm and dry and inhibit bacterial growth to some extent, their electric heating components are in direct contact with the towels, posing a risk of electric shock and other personal safety hazards. Inaccurate temperature control and large temperature fluctuations result in poor overall antibacterial and sterilization effects. Excessively high temperatures reduce the effectiveness of sterilization and can also cause towels to lose their toughness, damage the natural structure of the fibers and the protective layer on the surface, making the towels stiff and shortening their lifespan.
[0004] In response to the aforementioned problems of safety hazards, large temperature fluctuations, high energy consumption and lack of economy, and inability to dry in a timely manner, this utility model designs a water bath drying cabinet for bathrooms. Utility Model Content

[0013] This utility model has the following beneficial effects: 1. This utility model utilizes the cabinet, inner liner, and immersion electric heating rod to fill the inner liner with a liquid heat-conducting medium, thereby separating the electric heating components from textiles such as towels and bath towels, preventing direct contact. This has the advantages of ensuring personal safety during daily use and maintaining the stability of the drying temperature.
[0014] 2. This utility model utilizes the function of filling the inner tank with a liquid heat-conducting medium. Since pure water, as a liquid heat-conducting medium, has a large specific heat capacity, it has an extremely strong ability to store heat. It will not rapidly heat up or cool down due to short-term power fluctuations or start-stop cycles. This creates a highly stable and uniform drying environment, which can accurately maintain the optimal sterilization temperature range, completely eliminate local overheating, and thus protect the towel fibers while efficiently sterilizing them. At the same time, the working temperature is gentle, which eliminates the risk of high-temperature ignition from a physical principle, greatly improving the safety and reliability of the equipment.
