Description

An electric bed warmer

technical field

The invention belongs to the technical field of household heating equipment, and particularly designs an electric heating bed warmer.

Background technique

In order that people can still sleep in warm beds in winter, many kinds of heating products have been designed. At present, bed warming products on the market mainly involve electric mattresses that use electric energy for heating, and bed warming equipment that heats through the circulation of thermal media, but both have deficiencies. The former has the following disadvantages: (1). Heat radiation directly heats the fabric of the mattress and the surrounding air, causing people to experience dry mouth, itchy skin, and general discomfort after falling asleep. (2) The heating wire is only protected by the insulating sheath and directly bears the weight of the human body. Due to extrusion, wear, twisting and other reasons, the heating wire often breaks, catches fire, and leaks electricity, which is poor in safety. The latter (1), add hot medium to the circulating hose on the bed, and connect it with the heating melter water pump, the circulation speed is fast, forming a person lying on the bed, the temperature difference between the feet and the back is almost zero: there is no solution to the problem of electricity The quilt has a dry and baked feeling, which causes people to often feel dry mouth, itchy skin, general discomfort and other adverse reactions after falling asleep. (2) Add hot medium to the circulating hose on the bed and connect it to the heating melter. There is no circulating pump, and the hot medium circulates naturally by the thermal effect. Although this product has a good temperature difference between the feet and the back, However, in the process of use, gas is easy to grow in the hot medium circulation pipeline, thus forming an air block, so that the hot medium cannot be circulated and heated.

Contents of the invention

In order to solve the technical problems in the known technology, the present invention provides a non-electromagnetic radiation, automatic temperature control, excellent temperature difference control between the feet and the back, no air blockage in the hot medium circulation pipeline, and safe use of electric heating bed warmer.

The technical act that the present invention takes for solving the technical problem existing in known technology is:

An electric bed warmer, comprising a ptc liquid heater, an automatic deflation valve, a water storage container, a circulating pump, a circulating pump governor, a main heating pipeline, a temperature controller, an indicator light, and an overload insurance tube, and is characterized in that : The liquid outlet and inlet of the ptc liquid heater, the lower part of the water storage container has a liquid supply port and a liquid return port, the upper part of the water storage container is provided with a water inlet, and the liquid medium circulation pipeline includes the outlet of the ptc liquid heater The liquid port is connected to the main heating hose and the automatic air release valve, the main heating hose is connected to the liquid return port of the water storage container, the liquid supply port of the water storage container is connected to the circulating pump, and the circulating pump is connected to the lower liquid inlet of the heating container; The ptc liquid heater is provided with a temperature-sensing probe, the temperature-sensing probe is connected to a thermostat, and the circulation pump governor is connected to the circulation pump.

The present invention has also taken following measures:

The circulating pump governor adjusts the flow rate of the liquid medium of the circulating pump, thereby changing the flow rate of the liquid medium in the main heating pipe and adjusting the temperature difference generated from the feet to the back on the bed.

The advantages and positive effects of the present invention are: because the present invention adopts the above-mentioned structure and adopts the circulation pump to circulate the liquid medium, the gas phenomenon of the circulation pipeline is avoided, the heating is faster, and the use is more convenient; in the present invention, the designed circulation pump The governor adjusts the flow rate of the liquid medium of the circulating pump to change the flow rate of the main heating pipe, thereby changing the flow rate of the liquid medium in the liquid circulation line of the main heating pipe, so that the temperature of the entire bed surface is gradually reduced from the soles of the feet to the back. It is more comfortable for people to lie on it, it is more in line with people's sleep biological clock, and it is safer.

Working principle: First, place the electric bed warmer of the present invention at a place not lower than 12 of the bed, and put the main heating pipe 6 from the end of the liquid outlet 1-1 of the ptc liquid heater 1 from the end of the bed to the top of the bed Circling laying, then fill the water storage container 4 with the liquid medium along the water inlet 5, turn on the power, the circulation pump 3 starts to work, and continue to add water to the water inlet 5 at the same time, until the water level reaches one-third of the water storage container 4 , and when the water level no longer drops, stop adding water, and adjust the thermostat 10 to the sleeping temperature suitable for oneself.

Adjust the circulation pump governor to change the flow rate of the circulation pump to adjust the temperature difference on the bed surface. The greater the flow rate of the circulation pump, the smaller the temperature difference between the feet of the bed surface and the back. The temperature difference on the back is large.
