Abstract

The utility model belongs to a household water heating blanket which can not generate electromagnetic fields harmful to human bodies and is not easy to overheat and to result in fire. The utility model is composed of a control box and a woollen blanket, wherein, the inner of the control box body is provided with an electric heater, and a switch transformer and an electric machine are installed on a control box cover; the electric machine is connected with a pump in the control box body and the pump is connected with a water pipe in the woollen blanket. The utility model has the advantages of easy fabrication and convenient operation, and the utility model can be used both in winter and in summer.

Description

A kind of hydrothermal blanket

The utility model belongs to a kind of small household appliance, the hydrothermal blanket that specifically a kind of water heats.

At present, the electric blanket of selling on the market all is to adopt the spiral heating wire to be embedded in cotton blanket or other silk fabrics to make, can around the spiral heating silk, produce magnetic field in the use, and magnetic field is harmful to the pregnant woman, it is one of physical factor that causes fetal anomaly, and magnetic field also can make the electric blanket user produce the sense of mouth parched and tongue scorched.In addition, electric blanket generally all uses in the winter time, and just be out of use basically summer.

The purpose of this utility model is exactly a kind of hydrothermal blanket that can eliminate magnetic field of invention, not only is fit to the pregnant woman and uses, and make common user exempt the hardship of mouth parched and tongue scorched, and can warm oneself winter, and can lower the temperature summer.

The utility model is to realize like this, it is made up of control cabinet woollen blanket, water pipe, it is characterized in that: a heater is arranged at the control cabinet bottom, and a bimetal leaf is arranged in the heater, is connected with the outer temperature adjustment knob of control cabinet, the control base plate is arranged on the case lid, on the control base plate battery main switch is housed, heater button is also fixed a motor on indicator lamp, transformer, the case lid, the motor line is connected by the interior pump of a sealed tube and case, and pump is connected with the woollen blanket inner conduit by water pipe.On the control base plate loudspeaker is housed also.Also have a buoy in casing, buoy can be connected with the upper contact on the case lid at the connecting rod on the fulcrum by one, and the connecting rod other end is equipped with the contact.

The utility model has the advantages that, can not leak electricity in the process of heating and overheated, can breaking out of fire, can not produce the sensation of the mouth parched and tongue scorched that the magnetic field of electric mattress causes and to the harm of human body, winter, Xia Jieke use, and be cool in summer and warm in winter.

Below in conjunction with accompanying drawing the utility model is done further detailed description.

Fig. 1 is the utility model structural representation.

Fig. 2 is circuit theory diagrams.

1 is that thermoregulation knob, 2 is that casing, 3 is that water, 4 is that upper contact, 5 is that contact, 6 is that connecting rod, 7 is that buoy, 8 is electric former master switch K among the figure ₁, 9 be heater button K ₂, 10 be indicator lamp LT, 11 for loudspeaker, 12 for transformer, 13 for the control base plate, 14 for motor D, 15 for case lid, 16 for sealed tube, 17 for pump, 18 for water pipe, 19 for woollen blanket, 20 for resistive heater.Control cabinet can adopt transparent plastic or lucite to make, and motor, pump, transformer, loudspeaker, indicator lamp, heater, water pipe, woollen blanket are outsourcing, and it is 6～8 millimeters heat resistant plastice water pipes that water pipe is selected diameter, and connecting rod and contact are made of copper.Buoy is made of plastic, also has copper to become the contact above, and seeing figures.1.and.2 to install gets final product.(220V) opening power that plugs in master switch K ₁, the 12V of transformer output at this moment voltage, indicator lamp is luminous, and the driven by motor pump working impels the water circulation in the woollen blanket inner conduit.Open K switch ₂, adjust thermoregulation knob to the temperature of wanting, heater work, water temperature raises, woollen blanket is just warm, when water temperature arrived the temperature of wanting, it is outwardly-bent that bimetal leaf is met heat, and the contact separates, the heater dead electricity, quit work, when water temperature dropped to uniform temperature, sheet metal curved inwardly, the closing of contact., heater gets electricly starts working again, goes round and begins again, and buoy is arranged on the water surface, and the buoy other end is equipped with copper sheet, when water level descends, utilizes lever principle, and the buoy decline other end raises, and makes K ₄Two contactings, loudspeaker is piped, the warning water level is crossed and low should be added water in casing.

The utility model realizes that easily, winter Xia Jieke uses, and is fit to promote the use of.
