The heating module 30 of the mica heating type and the controller 60 electrically connected to the heating module 30 to be heated to a temperature close to the body temperature or heated to a high temperature so that the heat generation to the heating module 30 can be controlled. do.

In addition, a temperature input pad 50 electrically connected to the controller 60 and provided with a rotary switch 52 may be integrally mounted to the controller 60 so that heating temperatures for the various medical instruments can be designated.

In the warmer 100, the heated tank 10 is a cylindrical container shape of stainless steel having a height of about 250 mm and an inner diameter of about 65 mm, and a lower portion of about 50 mm and a circular cap shape. The heating tank 20 is fastened.

An elongated temperature sensor 40 is fixed to the wall surface of the heating tank 10. The temperature sensor 40 is a thermocouple in which copper and constantan are thermally bonded, and each material generates different electromotive force according to the water temperature in the heating tank 10. The difference in electromotive force is received by the controller 60 as an analog signal and converted into a digital signal, based on which the water temperature can be detected.

The temperature sensor 40 is electrically connected to the A / D converter 62 in the controller 60 to convert the sensed signal of the analog form detected by the generation of electromotive force into the digital signal in the A / D converter 62 do. Accordingly, the converted digital signal, that is, the water temperature detection signal in the heating tank 10 is sent to the microcomputer 61 electrically connected to the A / D converter 62.

The microcomputer 61 processes the digital signal according to the drive program data stored in the memory 63. At this time, a temperature input pad 50 is integrally installed at the side of the controller 60. 50 is electrically connected to the A / D converter 62, and when the water temperature is input by the rotary switch 52, the input analog signal is converted into a digital signal and sent to the microcomputer 61. do.

By the way, the temperature input pad 50 is a circular panel 51 in which the temperature is displayed along an arc in units of degrees Celsius (° C.), for example, 25, 36.5, 50, 75, 100, and the panel 51. And a rotary switch 52 installed at the center of the rotary switch 52. At this time, the tip of the rotary switch 52 is marked with an arrow type to rotate the rotary switch 52 to indicate the water temperature indicated by the arrow type. It is sent to the D converter 62 as an analog signal.

Accordingly, the microcomputer 61 transmits the currently detected water temperature and the designated water temperature input from the temperature input pad 50, and the microcomputer 61 may adjust the water temperature based on the designated water temperature. The power line 31 of the heating module 30 is electrically connected.

The heating module 30 is fixed in a form that is bonded or fastened to the lower bottom of the heating tank 10, and is installed in the upper portion in the heating tank 20 coupled with the heating tank 10 positionally. The heating tank 10 can be heated as the power is applied.

In addition, a lower end of the heating tank 10 is formed by constantly digging the outer side of the rim into an inner side, and a first step 11 having threads formed along the height direction at the outer circumference thereof. And the upper portion of the heating tank 20 is formed by the inner side of the rim is formed in the outer periphery so as to correspond in shape to the first step 11, the second screw thread is formed on the inner circumference to be fastened to the first step 11 Stepped step 21 is provided.

The upper portion of the heating tank 20 may be coupled to the lower portion of the heating tank 10 by the corresponding shape and fastening coupling of each step 11 and 21. At this time, the power line 31 is electrically connected to the heating module 30 through the lower center of the heating bath 20. The power line 31 is also a microcomputer 61 of the controller 60. Is electrically connected to

Accordingly, the microcomputer 61 compares the sensed water temperature with respect to the designated water temperature, that is, the sensed water temperature in the heated tank 10, and if the sensed water temperature is numerically higher than the designated designated water temperature, a heating module. The power supply 30 is turned off to stop the heating of the heated tank 10, and when it is low, the power is turned on to perform the heating.

At this time, by rotating the rotary switch 52 of the temperature input pad 50, when the arrow type of the tip designates about 36.5 ° C. close to the normal body temperature, for example, the heating module 30 in the heating tank 10 accordingly. The temperature of the water is controlled while the degree of heating of.

The heating wires 30a are all electrically connected to the power line 31, and the power lines 31 are electrically connected to the microcomputer 61 of the controller 60.

When power is applied to the power line 31 and resistance heat is generated in each heating wire 30a, the generated heat is transferred to the mica 30b in the form of a plate and spread along the surface. At this time, since the heating module 30 is installed in close contact with the bottom of the heating tank 10, the heat emitted from the mica is transferred to the heating tank 10 via the upper portion of the heating tank 20. The water in the heating tank 10 and medical instruments such as the surgical scrubber 200 and the tweezers 300 may be heated.

At this time, by rotating the rotary switch 52 of the temperature input pad 50 to adjust the water temperature to about 36.5 ℃ close to the normal body temperature, the water temperature input according to the designation via the A / D converter 62 and the microcomputer ( 61 is transmitted as a digital signal.

Accordingly, the driving program data of the memory 63 is loaded, and the microcomputer 61 compares the sensed water temperature in the heating tank 10 with the designated water temperature numerically so that the sensed water temperature is lower than the designated water temperature. For example, when the detected water temperature is about 20 ° C., the power is applied to the power line 31 of the heating module 30 to operate the heating module 30.

Accordingly, the heating module 30 is heated while the heating module 30 is heated, and the temperature sensing sensor 40 detects the elevated water temperature while being heated and continuously sends the heated water to the microcomputer 61, and the microcomputer 61. In comparison with the designated water temperature, if the specified water temperature is about 36.5 ° C. or more, the power supply to the power supply line 31 is stopped.

In addition, if the medical device in the heating tank 10 to be sterilized at a high temperature, the input pad 50 designates the rotary switch 52 at a relatively high temperature, for example, about 100 ° C., and thus detects the temperature. The degree of heating of the heating module 30 is adjusted by comparing the sensed water temperature sent from the sensor 40.
