Steam type electric heating blanket

Abstract

The invention discloses a steam-type electric blanket with heating pipes evenly distributed between an upper blanket surface and a lower blanket surface of the electric blanket. The heating pipe is a permeable hollow air pipe and the two ends of the air pipe are externally communicated with a steam-type electric heater; the steam-type electric heater is provided with a liner of a container fixed in a container shell and a water filling hole arranged on the shell and the upper part of the liner; the bottom of the inner container contacts and fixes a PTC heating ceramic tray; a steam chamber and a countersteam chamber of the inner container are respectively communicated with the two ends of the air pipe; wherein, the steam chamber is communicated with the inner cavity of the inner container by a steam inlet and the countersteam chamber is sealed and separated from the inner container and the steam chamber; one end of a temperature controller on the outer part of the shell is connected with a power supply and the other end is connected with a gas pressure transducer and a temperature transducer; the gas pressure transducer is arranged on the upper part of the steam chamber and the temperature transducer is arranged on the upper part of the countersteam chamber; the upper part of the countersteam chamber is provided with an air discharging valve. The invention adopts the hollow guide pipe for steam heating, thus avoiding dry indoor air and having the functions of dry combustion prevention and overpressure protection.

Description

technical field [0001] The invention relates to an electric blanket for heating a bed in winter. Background technique [0002] The structure of the electric heating blanket used in the family at present is that metal electric heating wires are evenly arranged between the upper and lower blanket surfaces, heat is generated through metal conduction, and a safety layer is wrapped outside the metal electric heating wires. Some electric blankets also have additional functions such as health care, temperature control or humidification and anti-drying, but the principle is still to generate heat through conductive metal wires. The defects of this structure are: [0003] 1. Most electric blankets use high and low temperature control, and it is difficult for the human body to get a more comfortable temperature. [0004] 2. The heat is generated by the conductive metal. When the temperature is high, the metal is easy to cause burns to the human body. [0005] 3. It is easy to cause ...

AI Technical Summary

Problems solved by technology

[0007] Because the temperature of the traditional electric blanket cannot be adjusted and controlled smoothly, and the air will be dry during use, affecting the comfort and health of the human body and other reasons, it can no longer meet people's needs for quality of life.
