Description

Electric blanket temperature control device module

The present invention relates to a temperature control device module for an electric blanket, in particular to a thermostat blanket temperature control device module in which a plurality of control elements are collectively arranged in a control box body to form a modular design.

According to the conventional electric blanket, a heating wire having a metal electric heating wire is embedded in the electric blanket, and the heating wire is connected to the mains socket via the power cable to provide the energy required for the metal heating wire to be actuated by the power of the commercial power. In order to provide users with convenient control of the heat energy emitted by the heating line, the existing electric blanket usually has a control unit between its heating line and the power line, as shown in the sixth figure, which is a common electric blanket available on the market. (6), which is mainly provided with a control box (64) between the power line (61) for plugging the mains and the heating line (63) embedded in the electric blanket (62), and is arranged on the control box (64). There is a button or a turntable and the like, and the control circuit installed in the control box (64) is driven by a button or a turntable to adjust the current of the input mains, and then output to the heating line (63) to control the heating line ( 63) The electric heating wire inside emits heat energy. Please also refer to the seventh figure. Another manufacturer has developed another type of electric blanket (7), which is mainly set up between the power line (71) plugged into the mains and the heating line (73) embedded in the electric blanket (72). The control box (74) further comprises a transformer (75) between the control box (74) and the power line (71). Thus, the transformer (75) is used to convert the alternating current into a stable direct current to prevent the voltage. Unstable AC power causes damage to the internal circuitry of the control box (74).

However, in the design of the above two electric blankets (6) and (7), the control boxes (64), (74) and the power cables (61) and (71) are placed on the ground or the tabletop, when people want to adjust the electric heating. When the temperature of the blanket is high or low, the control boxes (64) and (74) placed on the ground or the table top must be connected with the power cables (61) and (71) connected to the control boxes (64) and (74). The ground or the table is picked up to adjust the temperature of the buttons or dials provided on the control boxes (64) and (74), so it is extremely inconvenient to implement, and the control box (64), (74) and connection The power cables (61) and (71) of the control boxes (64) and (74) are quite heavy overall, so that the user can place the control box (64) and (74) on the ground or the desktop to pick up the operation. Inconvenience.

Please also refer to U.S. Bulletin No. 3422244, "The Temperature Sensing Control Circuit of Electric Heating Blanket", which mainly uses the electric blanket of the controlled rectifier to control the heating element of the electric blanket, and uses the temperature sensing tool to select the electric blanket to be used. To heat the temperature of the sleeping area, a temperature sensing tool is applied to the control circuit connected to the step-controlled rectifier to control the conduction of the controlled rectifier to maintain the sleeping area at a desired temperature; In the temperature sensing control circuit of the electric blanket of No. 3422244, the conductive wire formed between the control button and the plug is exposed outside the electric blanket, and is fixed to the control button, and the light is exposed outside the electric blanket and fixed The conductive wire of the control button is extremely easy to be damaged by the force when it is used, and the conductive wire and the plug which are dropped outside during handling and storage also cause inconvenience in handling and storage, and when the electric blanket When the dirt is cleaned and washed, the conductive wire and the plug exposed to the electric blanket and fixed to the electric blanket may also cause the difficulty of cleaning and washing the electric blanket.

Please also refer to "Electrical Heating Device with Temperature Control Tool" of US Pat. No. 3,437,792, which mainly comprises an electric blanket having a three-material connecting layer, and the third layer is between the first and second layers and Having a heating element that extends substantially coextensively with the area to be heated, the second layer having sufficient area to fold into the bed when the heating device is used as a blanket, the first layer having Sufficient area to be used as a decorative bed cover, and a temperature protection switch is arranged in the second layer to cut off the power when the temperature is higher than the limit temperature, and a temperature selection tool is arranged in the first layer. The temperature selection tool includes a transistor and an adjustment switch, and the adjustment switch can control the transistor to adjust the current of the mains input by the power line set on the first layer, and then output to the heating element; U.S. Patent No. 3,437,792, "Electrothermal Device with Temperature Control Tool" is set in the first layer of the electric blanket to contain the temperature of the control transistor and the temperature of the electronic components such as the switch. The selection tool and the power cord set on the first layer for the mains input are quite heavy, and the heavy weight selection tool and the power cord set on the electric blanket are added to the user to cover the electric blanket. The heavy inconvenience.

In addition, the U.S. Bulletin No. 3422244, "The Temperature Sensing Control Circuit of Electric Heating Blanket" and the "Electrical Heating Device with Temperature Control Tool" of U.S. Patent No. 3437792, can only detect the temperature condition by physical feeling, and cannot rely on vision.
