Heating pad for bed

Abstract

The invention discloses a heating pad for a bed, belonging to the technical field of bedclothing. The heating pad for the bed comprises a heating body, a covering layer and a group of superlong wave devices, wherein the heating body is in a rectangular shape; the covering layer is covered on one side of the heating body, and the group of superlong wave devices are laid on the heating body. The heating pad for the bed is characterized in that the heating body comprises a heating conducting wire fixation layer and heating conducting wires, wherein the heating conducting wires are combined on the heating conducting wire fixation layer in an identical circulation bending way; the group of superlong wave devices are mutually connected in series and laid on the surface of the heating conducting wire fixation layer toward one side of the covering layer; a thermostat is connected in series to circuits of the heating conducting wires, and the surface of the heating conducting wire fixation layer toward one side of the covering layer is provided with a temperature sensor, wherein lead-out ends of the heating conducting wires, the superlong wave devices, the thermostat and the temperature sensor all lead outwards, and the covering layer is a metal plate. The invention has the advantages of heat supply for sleepers to be beneficial to expelling cold, good heat transfer effect and firmness guarantee for use safety, and health-care effect for sleepers.

Description

technical field [0001] The invention belongs to the technical field of bedding, and in particular relates to a heating pad for a bed. Background technique [0002] With the continuous improvement of people's living standards, a fundamental change has taken place in the understanding of mattresses, that is, softness is no longer considered as the only factor, but it is hoped that mattresses will not only help improve sleep quality, but also benefit health care, and also It is beneficial to keep out the cold and keep warm. The heating pad for the bed can basically meet the above-mentioned requirements that people expect, and there are many technical solutions with the heating pad for the bed in the Chinese patent literature. Just to give a few examples: authorized announcement number CN201001546Y recommends a massage and heating mattress, which is composed of vibrating massage parts and heating sheets in the mattress, an inner shell of the vibrating massage parts, a driving m...

Problems solved by technology

Just to give a few examples: authorized announcement number CN201001546Y recommends a massage and heating mattress, which is composed of vibrating massage parts and heating sheets in the mattress, an inner shell of the vibrating massage parts, a driving motor and an eccentric block. It has both massage effect and heating and warming effect, but the vibrating massager will affect the sleeper's sleep when it is working, and it is not favored by people because of the noise; another example: CN2011123593Y introduces a heating element And the mattress of loess, this scheme uses the heating element to increase the temperature of the granular loess laid between the heating element and the sponge, and releases the trace elements contained in the loess particles that are beneficial to the human body to achieve the dual functions of heating and health care , but the production of this kind of mattress is relatively troublesome, especially in the process of storage, transportation and even use, once the mattress is in a vertical state, the loess will have a dumping effect, which will affect the flatness of the mattress; also as provided by CN201316051Y The plane heating device installed in the mattress, this scheme has positive significance for dispelling cold, especially for those suffering from rheumatism, but it has a single function, and it does not have other functions besides simply providing heat, such as what people expect Health care function; furthermore, for example: the heating pad disclosed by CN201430699Y mainly adds a high-carbon heating net to the inner side of the upper surface layer of the pad cover of the heating pad, and adopts flexible filaments and alternating wires in the vertical and horizontal directions of the heating net. Hard synthetic resin filaments are woven to obtain a uniform temperature on the surface after the heating element is installed inside, and to protect the heating element. This solution also has the disadvantages of troublesome production and single function

[0003] A representative example is the heating plate used for mattresses disclosed by the authorized announcement number CN2728320Y. This patented scheme can have both cold repelling and health care effects, but because the upper and lower covers are covered with cheap moisture-proof paper, it is very easy to damage, resulting in the exposure of heating wires, thermostats and sensors, there are unsafe hidden dangers in use, especially: the heat transfer effect of the moisture-proof paper used as the covering layer will not show the degree that people expect, and the moisture-proof paper prone to brittle cracking
