A support member protrusion 1375 is formed on the outer side of the module support member 1370 and radially outwardly and elastically deformed while the support member protrusion 1375 supports the upper side of the knob engagement member 1530.

The temperature controller 1500 can adjust the temperature by a predetermined temperature range in the process of rotating and rotating the user's hand, and the adjusted temperature can be displayed on the LED module 1300 and recognized by the user.

The dial knob 1510 protrudes outward so that the user can hold the hand. A module cap hole 1351 extends through the center of the dial knob 1510 so that the module cap 1350 coupled to the module supporting member 1370 surrounding the display member 1310 is exposed. The dial knob 1510 is provided with three dial latching portions 1513 for example and the dial latching portion 1513 is engaged with the dial binding portion 1533 of the knob coupling member 1530, It is preferable that they are coupled in a slip-on manner.

The plate engaging portion 1535 protruded in three directions in the up-and-down direction and the plate engaging portion 1551 formed in the sliding plate 1550 are slidingly engaged with each other and rotated at the same time inside the handle engaging member 1530. That is, the outside of the knob engagement member 1530 is coupled to the dial knob 1510 and the inside is coupled to the sliding plate 1550, respectively.

A plate engaging portion 1551 slidingly engaged with the plate engaging portion 1535 is recessed at a predetermined length from the upper end of the sliding plate 1550. A sliding plate 1553 having a thin plate-like cylindrical shape having conductivity and a sliding spring 1555 protruding from the sliding plate 1553 like a leaf spring and bent to be elastically deformable are formed on the lower edge of the sliding plate 1550 For example, five. Further, as shown in Fig. 4B, a split projection latching portion 1557 is formed on the upper side of the lower skirt of the sliding plate 1550 in a wavy radial manner.

The sliding spring 1555 elastically presses the sliding plate 1550 against the pattern member 1570 and selectively contacts the conductive pattern of the pattern member 1570 while rotating.

The pattern member 1570 is rotated by the rotation of the dial knob 1510 to selectively contact the sliding plate 1550 having the sliding spring 1555 to transmit the adjusted temperature to the substrate unit 1200, To the LED module unit 1300 to display the temperature on the display member 1310. [ On the other hand, a rib-shaped pattern skirt 1579 extending upward from the inner circumferential side and the outer circumferential side of the pattern member 1570 is formed so that the lower side of the sliding plate 1550 is stably rotated into the space between the pattern skirts 1579 Guide you to do.

5) of the ground pattern 1571 in one direction (counterclockwise in FIG. 5) with the ground pattern member 1570 as a ground at the center (or between) The first channel pattern 1573 partially exposed to contact with the ground pattern 1571 is partially exposed to the sliding spring 1555 in the other rotational direction of the ground pattern 1571 And a second channel pattern 1575 are provided.

The exposed angles of the exposure patterns 1573a and 1757a may be referred to as '? 1c,? 1e,? 1g,? 2c,? 2e and? 2g' in FIG.

That is, although the first channel pattern 1573 and the second channel pattern 1575 are formed as one conductor (see the dotted line in FIG. 5), the dotted line portion is embedded in the synthetic resin and the first exposed pattern 1573a and the second channel pattern 1575 2 Exposure pattern 1575a is only exposed.

With this structure, when the user rotates the dial knob 1510 clockwise or counterclockwise, the sliding spring 1555 contacts each of the exposure patterns 1573a and 1575a and the ground pattern 1571, It is possible to control the temperature range of the display unit 1310 to which the temperature of the display unit 1310 is to be applied and determine whether the rotation direction is clockwise or counterclockwise.

This will be described with reference to Table 1 below.

directional Ground pattern The first channel pattern The second channel pattern (Forward direction)
↓ (Reverse direction)
↑ Ground pattern OFF OFF ON OFF OFF ON ON ON

That is, as shown in Table 1, the ground pattern 1571 is always in contact with the sliding spring 1555 at all times, and the electrical connection between the ground pattern 1571 and the first channel pattern 1573 and the second channel pattern 1575 ON " and " OFF " That is, when the ground pattern 1571 and the first channel pattern 1573 are in contact with the sliding spring 1555, the substrate unit 1200 can determine that the ground pattern 1571 and the first channel pattern 1573 are 'OFF'.

A single click (for example, a wedge-shaped split projection catch 1557 and a split projection catch 1590 of the pattern fixing member 1590) (To be programmed in advance on the substrate unit 1200), the temperature of the substrate portion 1200 is set so as to be displayed by the LED module unit 1300 ) Can be controlled based on the information shown in Table 1.

On the other hand, the pattern fixing member 1590 is provided with a split projection 1591 having a wavy pattern engaging with the split projection engagement portion 1557. When the user turns the dial knob 1510, You can feel the movement of clicks by hand. This feeling can be felt more effectively by the resilient pressing spring 1555. The pattern fixing member 1590 is firmly supported on the substrate portion 1200 by the fixing pins 1593.

According to the above-described structure, the module legs 1330 are fixed to the module support member 1370 and are coupled with each other by a structure in which they do not have a structure such as bolt connection or the like, so that they can be intermeshed or sliding, .
