Abstract

The utility model discloses an electric bedding, relating to an electric bedding which is laid on a bed and is used for warming. The utility model is developed in order to solve the shortcomings that the AC magnetic field of the existing electric bedding does harm to human bodies, the safety is not good, the range for the adjustment of temperature is narrow, etc. The method is mainly that a line is provided with a tap changer and a rectifying filtering circuit, and a shielding layer is additionally arranged on a bedding surface. The utility model has the advantages that the DC heating electromagnetic field is stable, the affection of the electromagnetic field to the human bodies is small, the use is safe, and the temperature can be discretionally adjusted.

Description

A kind of electric mattress

The utility model relates to warm oneself the in bed electric mattress of usefulness of a kind of shop.

Existing electric mattress all is directly to use 220 volts alternating currents to heat to heating wire, and the ac magnetic field that produces during energising is harmful, when heating wire like disconnected non-when disconnected the electric arc of generation also cause fire easily; And the switch of this electric mattress generally has only two grades of high temperature, low temperature, and thermoregulation range is narrow.

The purpose of this utility model be the design a kind of electromagnetic field more stable, less to the human influence, use safer, the electric mattress that thermoregulation range is big.

The purpose of this utility model can realize by following proposal: it comprises cotton-padded mattress face 1 and heating wire 2 in the cotton-padded mattress of making of textile, and we establish tap changer 4 and current rectifying and wave filtering circuit 5 in the place that heating wire and power line 3 join, and regulating circuit is arranged in the tap changer.The pressure regulation amplitude can lie prostrate for 0-220.

Also voltage regulating rectification circuit can be located on the socket, common electrical cotton-padded mattress attaching plug be inserted on this socket also can realize this purpose like this.

In order further to reduce the harm of magnetic field to human body, can set up screen 6 on the cotton-padded mattress face or on the insulating barrier of heating wire, the cloth of this layer available metal spraying is made.

The utility model has the advantages that: owing to set up current rectifying and wave filtering circuit on the line, heat to heating wire with direct current, dc electromagnetic field is stablized the influence that reduces human body, adds the protective effect of screen, and electromagnetic field is just very little to the influence of human body; Simultaneously owing to use direct current, also significantly reduce like the disconnected non-electric arc that produces when disconnected at heating wire, so use safer; Owing to adopt tap changer, temperature can be adjusted arbitrarily, just more can satisfy user's needs.

Accompanying drawing is a generalized section of the present utility model, among the figure: 1. cotton-padded mattress face in the cotton-padded mattress; 2. heating wire; 3. power line; 4. tap changer; 5. current rectifying and wave filtering circuit; 6. screen.

Embodiment: at first make cotton-padded mattress face 1 in the cotton-padded mattress, with evenly tortuous being clipped in the cotton-padded mattress in the middle of the cotton-padded mattress face of heating wire 2, to establish the regulating circuit in tap changer 4 and current rectifying and wave filtering circuit 5 (these can the have been bought from the market) tap changer be that 0-220 lies prostrate to the amplitude modulation of voltage an end of cotton-padded mattress face and the place that power supply joins in heating wire exposes cotton-padded mattress; Repurchase cloth with metal spraying to be sewn in the cotton-padded mattress or the cotton-padded mattress face on; Another kind of way is that screen is located on the insulating barrier of heating wire.

Claims

1, a kind of electric mattress, relate to and spread the electric mattress that bed is gone up heating usefulness, it comprises cotton-padded mattress face [1] and heating wire [2] in the cotton-padded mattress, it is characterized in that the place that heating wire and power line [3] join establishes tap changer [4] and current rectifying and wave filtering circuit [5], and regulating circuit is arranged in the tap changer.
