Description

Constant temperature hot-water heating pad

Technical field

The utility model relates to a kind of pad, especially a kind of constant temperature hot-water heating pad of its temperature of energy regulated at will.

Background technology

Along with season, climate flip, especially in the winter of cold and the summer of tight heat, people require more and more higher to the insulation and the cooling-down effect of pads such as mattress, seat cushion, bolster.At present, occurred on the market and can regulate the heat keeper of its temperature according to temperature and individual demand.The patent No. is: 03207200.7, name is called: cold/hot tatami mattress, Granted publication number is: the Chinese patent of CN2682933Y has just been announced so a kind of mattress, comprise pad, refrigeration/hot device, liquid reserve tank and circulating pump, pad comprises base wad layer and functional layer, functional layer is positioned at the base wad layer, and functional layer is connected in series by heat exchanger, circulating pump, the liquid reserve tank circulation of flexible pipe and described refrigeration/hot device.Described refrigeration/hot device can be semiconductor-type or compression.This cold/hot tatami mattress can be according to temperature Change and its temperature of individual demand regulated at will, and is easy to use.

But still there is following shortcoming in above-mentioned mattress: the heat exchanger cost of the refrigeration that is adopted/hot device is higher, and it keeps the effect of constant temperature unsatisfactory.

The utility model content

The purpose of this utility model is to overcome the shortcoming of above-mentioned technology, provides that a kind of cost is low, the thermal efficiency is high and changes in temperature pad that can automatic constant-temperature.

The purpose of this utility model is achieved in that a kind of constant temperature hot-water heating pad, comprise pad, heat-producing machine, liquid reserve tank, circulating pump and microcomputer controller, pad comprises base wad layer and functional layer, functional layer is positioned at the base wad layer, described heat-producing machine comprises heating element heater, temperature controller, liquid thermal conductivity plate and thermal source heat-conducting plate, functional layer is passed through water inlet pipe, return pipe and described heat-producing machine, circulating pump, liquid reserve tank circulates successively and is connected in series, described heating element heater is the PTC heat generating member, also can be the electrothermal tube more than one or, described heat-producing machine is except that being equipped with the line traffic control button, also configurable remote controller is controlled, described functional layer adopts one or more flexible pipe to be coiled to form, and is connected with the base wad layer of both sides.Described base wad layer is combined by in nonwoven, cotton felt, textile cloth, wood pulp straw mat, bamboo mat, bed cover, inflatable packer, water bed, sping mattress, palm fiber mattress, foam-rubber cushion, the latex pad one or more.

PTC heat generating member of the present utility model comprises the above PTC heating of one or a sheet, and is necessary between each PTC heating sheet and is connected in parallel.

PTC heating sheet of the present utility model can be disk, square sheet, also can be other shape.

When using electrothermal tube, can operate microcomputer controller and electrothermal tube be kept constant temperature by temperature controller as heating element heater.

Constant temperature hot-water heating pad of the present utility model can be used as mattress, bed, seat cushion, back cushion, bolster, cold and hot compress bag etc.

The PTC heat generating member is the ceramic heating element with positive temperature coefficient, after its two ends applies certain voltage, the PTC heating promptly automatically temperature rise enter resistance transition warm area, the resistive element surface temperature will keep certain value, this temperature is only with the Curie temperature of material and to apply voltage relevant, and is irrelevant substantially with environment temperature.Its power can be regulated automatically, in the utility model, also can regulate by microcomputer controller, has temperature from the limit ability, and the efficient height is safe and reliable.

Constant temperature hot-water heating pad of the present utility model compared with prior art has following good effect:

1) has the characteristics of automatic constant-temperature;

2) reliable operation, overtemperature never;

3) when using the PTC heat generating member as heating element heater, the non-constant width of operating voltage, when operating voltage changed 2 times, the variation of surface temperature was very little;

4) with low cost.
