The present invention relates to a controller for a thermal mat, and more particularly, to provide a braille to a speaker and an operation button for outputting a guidement for convenience for the elderly and the visually impaired, and to increase the reliability of temperature sensing to maintain the temperature of the mat. In order to prevent fire or burns caused by overheating, the temperature sensor is directly attached to the heating wire, and when the malfunction occurs due to the malfunction of the temperature sensor or when the malfunction occurs due to the interruption of the power supply, It relates to a visually impaired user to display and inform the user, and a thermal mat controller that is easy to use at night,

In addition, the present invention relates to a controller for a thermal mat having a scalar energy generating unit for generating scalar energy, inducing a comfortable sleep and promoting health.

Recently, as the desire for health promotion has increased, various efforts have been made to promote health. As part of such efforts to promote health, a thermal mat that can help you get enough sleep is widely used.

In general, the heating mat is provided with a heating wire inside to generate a desired temperature, and in addition to the magnetic field generating unit inside the mat to generate a magnetic field to help blood circulation to help the user to get a good night's sleep, and to generate a low frequency There is also a thermal mat that provides low frequency treatment.

The warm mat includes a controller for receiving a command signal according to a user's operation and controlling the warm mat according to the input command signal.

The controller of the thermal mat according to the prior art generally includes only a button for receiving a command signal and a display unit for displaying information on the driving state of the input command signal and the thermal mat as a means for the user's operation. In addition, it was quite inconvenient to control the use of the heating mat at night by turning off the lights and for the elderly and the disabled through the controller. In other words, the elderly and the disabled often do not know exactly what command signals they input to the controller, and often do not know exactly how the current driving state of the thermal mat is.

Therefore, it is necessary to provide a means for making it easier for the elderly and the disabled to control (manipulate) the controller. In the prior art, such means are not provided sufficiently.

In addition, the controller of the thermal mat is provided with a temperature sensor so as to constantly generate heat at a set temperature. According to the related art, a temperature sensor is disposed between heating wires in which the temperature sensor is arranged in a zigzag on a mat.

When the temperature sensor is placed away from the heating wire, the temperature sensor may not accurately detect the heating temperature of the heating wire by a fabric or other obstacle placed between the heating wire and the temperature sensor, and thus the heating mat may keep the set temperature constant. It may not generate heat, and in some cases, may overheat, causing burns or fire to the user.

Therefore, it is necessary to accurately detect the heating temperature of the hot wire to generate a constant temperature and to prevent burns and fires.

In addition, the controller generally includes a display unit which displays and displays a state of use of the thermal mat, for example, a set time of a timer, a heat set temperature of a hot wire temperature, and contents of a command signal input by a user through a button. In the heat sensor's heating temperature detected by the temperature sensor is displayed on the display, but the abnormal state of the temperature sensor is not displayed separately.

If there is a malfunction in the temperature sensor that causes a malfunction, which cannot detect the temperature, or a temperature sensor that detects a temperature but detects a temperature that is significantly different from the actual temperature, or an overheating or overcurrent of a heating wire. For this reason, when the power supply to the heating wire is cut off, the temperature sensor adjacent to (or in close contact with) the heating wire is cut off and the power supply is cut off. It is necessary to make it easy to check the cause of the occurrence and to eliminate the cause of the abnormality, the prior art does not notify the user by displaying it separately in the event of an abnormal temperature sensor.

And even if the power of the controller is turned off while the plug of the thermal batter is connected to an outlet, the controller of the thermal mat is small but consumes standby power continuously.

Therefore, even if the plug is not unplugged, it is necessary to cut off the standby power to save energy.

The present invention has been made in order to meet the problems and problems required by the controller of the thermal mat according to the prior art as described above, it is used by the elderly or blind people with a braille projection on the speaker and button for outputting the announcements An object of the present invention is to provide a convenient thermal mat controller.

In addition, when an abnormality occurs due to a failure of the temperature sensor and an abnormality occurs due to the malfunction of the temperature sensor due to the power cutoff during overheating or overcurrent, the display is displayed on the display to immediately check whether there is an abnormality in the temperature sensor and maintain it. It is an object of the present invention to provide a controller for a thermal mat to enable the.

In addition, by attaching the temperature sensor directly to the heating wire through the heat-resistant tape, it increases the reliability of detecting the heating temperature, maintains the heating temperature constant at the set temperature, and provides a thermal mat controller that can prevent burns or fire due to overheating. Another purpose.

In addition, another object of the present invention is to provide a thermal mat controller which prevents unnecessary power consumption by cutting off standby power without removing the plug from the outlet.

Hereinafter, a controller for a thermal mat according to the present invention will be described in more detail with reference to the accompanying drawings.

1 to 3, the thermal mat controller C according to the present invention includes a command input unit 10, a display unit 20, a speaker 30, a power supply unit 40, a constant voltage unit 50, and a temperature. The sensor 60, the blocking unit 70, the control unit 80, the case 90, and a relay RY and a self-generator 100 for blocking standby power are made.

In the upper portion of the front surface of the case 90 of the controller C shown in FIG. 2, a display unit 20 is provided to display and display a use state to the user. In the middle part, a command input unit for inputting a command signal according to a user's operation ( 10 is provided, the lower portion is formed with a plurality of heat dissipation holes 91 for dissipating heat generated inside the case 90 to the outside, one side of the middle portion is output from the speaker 30 built in the case 90 The speaker hole 93 is formed to effectively spread the voice.

The controller shown in FIG. 2A is a controller capable of independently controlling both sides of a thermal mat in a two-person thermal mat, and two command input units 10 are provided at both sides, and the display unit 30 is divided into half screens. Is displayed. The controller of FIG. 2B illustrates a controller for controlling a single person thermal mat.

The command input unit 10 includes buttons SW1 to SW4 for receiving a command signal by a user's manipulation.

The button as the command input unit 10 includes a power button SW1 for turning on and off the supply of external commercial power, an up-down temperature control button SW2 and SW3 for adjusting the heating temperature of the heating wire, and a timer for setting the heating time of the heating wire. Buttons SW4 and the like.

Each button has a braille protrusion 11 protrudingly formed to recognize the use of the button pressed by the user (ie, power on / off, temperature control, timer setting) with a finger sensation, and the speaker 30 is inputted. Outputs the announcement for the command signal and outputs an alarm sound when it is overheated or an abnormality occurs in the controller C,

Even if the elderly and the visually impaired do not check the contents of the command signal input by themselves through the display unit 10 or the command input unit 10, the elderly or the visually impaired can be manipulated in a precisely recognized state through the senses or the hearing.

As shown in FIG. 2, the display unit 20 displays the remaining time until the heat generation is stopped through a circular scale bar when the heat generation time of the heat mat is set through a timer, and displays the heat. When the heating temperature of the mat is set, it is possible to display and display the heating temperature set as a level. At this time, the circular scale bar of the timer is generally divided into a color-filled space and a colorless space, and the number of spaces filled with color indicates the remaining time until the heat generation is stopped, and the set heat generation temperature is displayed as a level. You can also display the set temperature directly as a number.

Although not shown, the contents of the command signal input according to the user's operation, the actual heating temperature of the current heating mat (that is, the temperature detected by the temperature sensor 60), and the heating mat are continuously heated without interruption. The contents such as the total time being used and the contents corresponding to the abnormality when the abnormality occurs in the controller can be displayed by being displayed on the display unit 20.

In particular, when an abnormality occurs in the temperature sensor 60, since the heating temperature control of the thermal mat is not normally performed, there is a danger of an accident such as a fire. It is desirable to prevent the occurrence of an accident and to maintain by displaying the information on the display. When there is an abnormality of the temperature sensor 60, it may be desirable to inform the user through the speaker 30 as well as the display unit 20.

When the abnormality occurs in the temperature sensor 60, there may be a case where the temperature sensor 60 is broken, and the power is not supplied to the temperature sensor.

When the temperature sensor 60 is broken, for example, the temperature sensor 60 does not detect the temperature itself and accordingly does not transmit a temperature signal to the control unit 80, and thus detects the temperature and the control unit 80. There is a faulty malfunction in the temperature detected. In a malfunctioning state, a temperature (eg, 100 degrees or more and minus 10 degrees or less) that the thermal mat cannot realistically detect as a temperature is transmitted to the controller 80, or the temperature of the thermal mat is continuously changed within an error range. Although the temperature detected by the temperature sensor and transmitted to the controller 80 may be intermittently changed out of the error range, such as 10 degrees to 20 degrees, 20 degrees to 30 degrees, and 30 degrees to 25 degrees.

And the temperature sensor 60 itself is not a failure, but when the overcurrent is applied to the controller (C) to cut off the power supply through the blocking unit 70 in order to protect the power supply to the temperature sensor 60 is cut off The temperature sensor 60 may be inoperative. Not only when overcurrent is applied, but also when the heating wire of the thermal mat is overheated, the power supply to the temperature sensor 60 may be cut off as well as the heating wire.

When the temperature sensor 60 is broken as described above, or power is supplied to the controller C, but the power supply to the temperature sensor 60 is cut off due to overcurrent, the user is notified of the contents to the user through the display unit 20. It is advisable to be aware of this and to maintain it when necessary. In particular, when the temperature sensor 60 is broken, there is a risk of fire due to overheating of the thermal mat. Therefore, it may be desirable to inform the user through the speaker 30 as well as the display unit 20.

The temperature sensor 60 detects the heating temperature generated by the heating wire 3 of the thermal mat 1 and transmits the generated temperature to the controller 80.

The temperature sensor 60 is directly attached to the heating wire 3 through the heat resistant tape to accurately measure the heating temperature of the heating wire.

Since the temperature sensor 60 is directly attached to the heating wire 3, the temperature sensor 60 can be more accurately sensed the heating temperature of the heating wire, thereby more precisely controlling the heating of the heating mat.

The power supply unit 40 is a fuse (F1) to protect the controller by disconnecting when the commercial AC power input is overcurrent, and the varistor absorbing and removing when the commercial AC power is connected in parallel to the input terminal when the overvoltage is included And a thermal resistance (PTC) for protecting the circuit by increasing the resistance value when the temperature rises, and a capacitor (C14) for removing noise included in the commercial AC power input.

The varistor RV1 of the power supply 40 is connected in parallel with an electric field sensor ES that detects an electric field strength of a commercial AC power input. The electric field strength detected by the electric field sensor is transmitted to the control unit 80, and the control unit 80 outputs a guide mat (or a warning sound) through the speaker when the input electric field strength is larger than a reference value, or through the display unit. Visually inform the user.

An electric field is formed on the power line through which AC power flows. The electric field is harmful to the human body, and the electric field strength of the electric field varies depending on the direction in which the plug is inserted into the outlet. Therefore, it is desirable to inform the user whether the plug is inserted into the outlet in a small electric field strength to help the user's health and safety.

The constant voltage unit 50 supplies a constant voltage driving power to the control unit 80, the blocking unit 70, the speaker 30, the command input unit 10, etc. by converting the input commercial AC power into a constant voltage.

The constant voltage unit 50 is a diode (D2, D3) for rectifying the commercial AC power, the capacitor (C5) for smoothing the rectified power, and another smoothing the smoothed power once again to output a constant voltage DC power Capacitor C4, resistor R26 and zener diode D4 for stabilizing the output constant voltage are included.

The cutoff unit 70 supplies power to the power supply unit 40 according to a control signal (that is, a trigger signal) transmitted from the control unit 80 when the temperature sensed by the temperature sensor 60 exceeds a reference temperature. By blocking so that the heating wire is not supplied to the heating wire, the heating wire is no longer overheated.

The blocking unit 70 is turned off when the trigger signal is input from the control unit 80, the zener diode D5 protecting the transistor Q4, and the transistor Q4 is turned off when the trigger signal is conducted. And a thyristor Q2 that cuts off the power supply of the power supply unit 40, and resistors R6 and R10 that protect the thyristor Q2.

Although the thermal mat 1 is not in use, the standby power blocking means for blocking standby power consumed since the plug is connected to the outlet includes a relay RY and a self-generator 100.

The relay RY is provided at a power line connecting the plug and the controller C, or is provided at an outlet to which the plug is connected, and the self-generator 100 is interlocked with the power button of the controller C or provided separately.

Figure 7 shows the scalar energy generation unit 200 to induce a good night's sleep and improve health through the increase of immunity and disease treatment.

The scalar energy, or scalar wave, is a longitudinal wave developed by Tesla, and Tesla advocated that it could send electrical energy anywhere on Earth to use it instead of ordinary electromagnetic waves.

Scalar waves can be used to cure many diseases.

One of D. bohm's theory of quantum fields is the Aharonov-Bohm effect, which, like the Mitch Russian doll, has a finer energy, quantum energy, inside the electromagnetic waves. In addition, there is a theory that zero-point energy, which is a finer energy, exists inside the quantum field energy. Quantum field energy is often referred to as scalar energy or scalar wave, and zero field energy is energy that fills the air in the universe. Since scala waves are highly ordered waves, they are known to be able to cure diseases regardless of the type of disease because the high density of scala waves flow to the place of the disease as if the energy flows from high to low. have. It is as if the polarity of the magnet changes when the permanent magnet encounters a stronger magnetic field than itself.

French scholar A.Priore and Canadian biologist Hulda R. Clark have used scala waves to treat terminal cancer, including Zapper and Russian physicist AE Akimov. It can be used to treat atherosclerosis, restoring suppressed immunity and eradicating sleep parasites.

Referring to FIG. 7, the scalar energy generating unit 220 includes an insulating tube 221 and a coil 223 wound around the insulating tube 221 in a spiral manner, and the scalar energy generating unit 220.

The scalar energy generation unit 220 is embedded in the case 90, and the generated scalar energy is discharged to the outside of the case 90 through the heat dissipation hole 91 or through a hole (not shown) that is separately drilled. .

At this time, the nodes 225, in which the coils 223 wound in a spiral reciprocate, intersect, are arranged in a straight line.

The two coils of the node 225, where the coils 223 intersect, form two positive and negative poles of the same magnitude as the current flows, and the two poles cancel each other's magnetic field to zero-field. At the same time, the two poles are facing each other in close proximity, and the energy is pushed to a high energy density to one side because the polarized vibrator shakes the zero point of space during the movement. At this point, a new wave of transverse shearing occurs, which is the scalar, that is, the scalar energy.

The magnitude of the scalar energy generated by the scalar energy generator 220 may be arbitrarily adjusted by the user through the command input unit 10. The command input unit 10 is provided with a down switch SW5 and an up switch SW6 so that the magnitude of scalar energy generated can be adjusted step by step. The set intensity amount of the scalar energy adjusted by the down switch SW5 and the up switch SW6 is displayed on the display unit 20.
