Description

The constant temperature hydrothermal blanket

Technical field

The utility model relates to a kind of daily necessities of heating warm-keeping, specifically is a kind of hydrothermal blanket.

Background technology

Owing to be subjected to the restriction of the energy and existing living conditions, people slept to warm oneself and adopted heating installations such as air-conditioning, hot-water bottle and electric blanket basically winter.Use air-conditioning, life cost is too high; Hot-water bottle not only concentrate but also the insulation duration is short by heat, is difficult to satisfy the requirement of comfortableness; Common electric blanket produces stronger electromagenetic wave radiation and induced electricity in the time of owing to heating, and use the grievous injury health for a long time, and can cause multiple disease, the improper use fire hazardous, the pregnant person of the old,weak,sick and disabled should not use electric blanket.Though the electric blanket and the hydrothermal blanket of some no electromagenetic wave radiation owing to complex structure, inconvenient operation and cost height, are not easy to promote at present.

Summary of the invention

The utility model is that a kind of constant temperature hydrothermal blanket will be provided, and this hydrothermal blanket not only can be selected by high and low temperature, and stable temperature control, and simple in structure, cost is low, and is safe and convenient to use.

In order to achieve the above object, the utility model adopts following technical proposals:

A kind of constant temperature hydrothermal blanket comprises flexible blanket body, and attemperater is characterized in: also comprise the rubber overflow pipe, miniature immersible pump, multifunction switch, high-critical temperature PTC resistance, low critical-temperature PTC resistance, electric heater; The snakelike rubber overflow pipe that is arranged with in the middle of the interlayer of flexible blanket body, rubber overflow pipe delivery port communicates with attemperater, miniature immersible pump delivery port in rubber overflow pipe water inlet and the attemperater is connected, form water circulation system, electric heater is housed in the attemperater, is connected into the high and low temperature heating circuit with high and low critical-temperature PTC thermistor respectively by multifunction switch.

Described attemperater top is provided with water filling port and steam vent, and outer wall is equipped with liquid level display.

The beneficial effects of the utility model are: after adopting above-mentioned temperature control loop, open miniature immersible pump by multifunction switch and make water circulation, and select required temperature shelves, connect the series loop of PTC thermistor and electric heater, electric current raises by the water temperature in the attemperater behind the electric heater, and after water temperature surpassed the critical-temperature (Curie temperature) of PTC thermistor, PTC thermistor resistance phase step type increased rapidly, cause in the loop electric current to descend, make that water temperature reduces in the attemperater.After water temperature reduced, PTC thermistor resistance reduced again, and loop current increases, and the electric heater temperature raises once more, goes round and begins again, and made within the temperature range about the water temperature maintenance PTC thermistor critical-temperature in the attemperater, had realized temperature stabilization control.

The utility model is simple in structure, and is with low cost, safety and comfort, and temperature is suitable, stable, and pregnant all convenient use of the old,weak,sick and disabled satisfied the requirement of life comfortableness, is a kind of desirable hydrothermal blanket.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1: constant temperature hydrothermal blanket of the present utility model comprises flexible blanket body 1, rubber overflow pipe 2, attemperater 3, miniature immersible pump 4, multifunction switch 5, attaching plug 6, high-critical temperature PTC resistance 7, low critical-temperature PTC resistance 8, electric heater 9, rubber overflow pipe water inlet 10, rubber overflow pipe delivery port 11, liquid level display 12, water filling port 13, steam vent 14.

Be provided with miniature immersible pump 4, electric heater 9, high-critical temperature PTC thermistor 7, low critical-temperature PTC thermistor 8 in the attemperater 3, have water filling port 13 and steam vent 14 on the attemperater 3, outer wall is provided with liquid level display 12.

Rubber overflow pipe 2 is snakelike and is arranged in the flexible blanket body 1, and rubber overflow pipe delivery port 11 is communicated with attemperater 3, and rubber overflow pipe water inlet 10 is connected with the delivery port of miniature immersible pump 4, forms water circulation system.Multifunction switch 5 is provided with the open and close and the high and low selection function of water temperature of miniature immersible pump 4, and is composed in series miniature immersible pump work loop and high and low temperature heating circuit with miniature immersible pump 4, electric heater 9 and high and low critical-temperature PTC thermistor 7,8 respectively by some leads.

Provided the heating temperature control circuit as Fig. 2, its course of work is as follows:

When the user needs higher temperature, attaching plug 6 is inserted into the 220V AC Power supply socket, and multifunction switch is pushed to as shown in Figure 3 the position of (a), connect the high temperature heating circuit, this moment, miniature immersible pump 4 was started working, water in the attemperater 3 is through the water circulation circuit cycle, electric current flows through electric heater 9 simultaneously, owing to just begun the critical-temperature that attemperater 3 interior water temperatures are lower than high-critical temperature PTC thermistor, electric current is bigger in the loop, water temperature in the attemperater 3 begins to raise, surpass 32 ℃ of the critical-temperatures of high-critical temperature PTC thermistor 7 when water temperature after, the resistance phase step type of high-critical temperature PTC thermistor 7 increases rapidly, and electric current descends in the loop, makes that water temperature reduces in the attemperater 3.After water temperature reduces, the resistance of high-critical temperature PTC thermistor 7 diminishes again, flowing through electric heater 9 electric currents in the loop increases, water temperature in the attemperater 3 raises once more, go round and begin again, water temperature in the attemperater 3 is remained within the temperature range of about 32 ℃ of high-critical temperature PTC thermistor critical-temperatures, realized the high temperature constant temperature heating.

When the user needs lower temperature, attaching plug 6 is inserted into the 220V AC Power supply socket, and multifunction switch is pushed to as shown in Figure 3 the position of (b), connect the low-temperature heat loop this moment, same principle just can realize the cryogenic thermostat heating.

Do not need to heat when only needing water to flow, multifunction switch is pushed to as shown in Figure 3 the position of (c), has only this moment miniature immersible pump to make continuous circulation of current and no longer heating.

When not using, just can in the position that multifunction switch can be pushed to as shown in Figure 3 (d).

In addition, use for the first time or after using a period of time, can when water level drops to a certain degree, can add water by liquid level display 12 observation attemperaters 3 middle water levels by water filling port 13.

During heating, producing a certain amount of gas in the attemperater 3 can discharge by steam vent 14.

Studies show that the sleeping quilt temperature of optimum is about 26-34 ℃.The utility model selects for use the critical-temperature of high and low critical-temperature PTC thermistor to be respectively 32 ℃, 25 ℃.
