Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a temperature control device for a cooker.

[0002]

[Prior art]

 As shown in FIGS. 10 and 11, a conventional temperature controller for an electric cooker is configured so that a lower guide member 1 and an upper guide member 2 are vertically combined and integrally joined with a screw 3 so as to face each other vertically. The guide rails 4 and 4'are configured.

A sliding member 5 is slidably fitted to the guide rails 4, 4 ′, and an operating lever 6 provided on the front surface of the sliding member 5 is formed on the lower guide member 1 in a horizontal slit. The rack 8 provided on the rear surface of the sliding member 5 is engaged with the pinion 10 of the temperature adjusting rod 9.

The lower guide member 1 is attached to the inside of the window of the cooker body 10, and the operating lever 6 is moved left and right to adjust the heating temperature.

[0005]

[Problems to be solved by the device]

 In the conventional temperature control device, the member for guiding the sliding member 5 is composed of two parts, the lower guide member 1 and the upper guide member 2, as described above, which is a factor of high cost. Further, since the lower guide member 1 and the upper guide member 2 are joined and integrated by the screw 3, there is a drawback that the resistance applied to the sliding member 5 is not fixed depending on how tight the screw 3 is tightened. .

Therefore, an object of the present invention is to provide a temperature adjusting device for a cooker that solves these problems.

[0007]

Means for Solving the Problems In order to solve the above problems, the present invention proposes that a sliding member for temperature adjustment is slidably supported by a guide member fixed to a cooker body, and In a temperature control device for a cooker having an operating lever on the front side, a guide groove is formed horizontally in the guide member, and a sliding claw provided in the sliding member is slidably suspended in the guide groove. It is configured to be fitted.

[0008]

[Action]

 In the above temperature adjusting device, the guide member is fixed to the cooker main body, the sliding claws of the sliding member are fitted into the guide grooves of the guide member, and the hanging is suspended. The rack of the sliding member is engaged with the pinion of the temperature control rod.

When the operating lever of the sliding member is moved to the left or right, the sliding claw slides in the guide groove, and the pinion engaged with the rack rotates.

【Example】

 As shown in FIGS. 1 and 2, an electric cooker according to an embodiment shown in the accompanying drawings comprises a cooker main body 11 and a pot 12 detachably mounted on the cooker main body 11.

The cooker body 11 includes a heat shield plate 14 mounted on the bottom plate 13, a heating device 15 provided on the heat shield plate 14, and a heat-resistant synthetic resin guard 16 surrounding the heating device 15. Is the main component.

As shown in FIG. 1, a part of the guard 16 is formed with a notch 17 that is open at its lower edge, and an operating lever 18 of the temperature control device projects into the notch 17.

As shown in FIGS. 3 to 5, the temperature control device has a guide member 19, a sliding member 21, and a cover member 22.

As shown in FIG. 5, the guide member 19 is formed of a flat plate having arc-shaped inner and outer edges along the inner peripheral surface of the guard 16, and a guide groove 23 is formed on the outer edge thereof. The guide groove 23 is formed by a channel-shaped groove that is open to the side of the guard 16. As shown in FIG. 6, a guide surface 24 along the guide groove 23 is formed on the back surface of the guide groove 23, and fine vertical ribs 26 are densely formed on the guide surface 24.

The sliding member 21 is also formed by a strip plate having arcuate upper and lower edges along the inner peripheral surface of the guard 16, and the U-shaped sliding claw protruding to the outer surface at the upper edge thereof. 27 are provided at three places at required intervals. An elastic piece 28 is integrally provided on the upper edge of the sliding member 21.

An operating lever 18 is provided at the center of the front surface of the sliding member 21, and spacing ribs 29 are provided at several positions on both sides of the operating lever 18. On the rear surface of the sliding member 21, a rack 31 in which vertical teeth are arranged in the horizontal direction is formed.

The cover member 22 is a strip-shaped member that is curved in an arc shape along the inner peripheral surface of the guard 16, and has a hole 32 for inserting the operation lever 18 in the central portion, and an upper end. A notch 33 into which the sliding claw 27 is fitted is formed at the edge.

The sliding member 21 has its sliding claw 27 slidably fitted in the guide groove 23 of the guide member 19, and the elastic piece 28 is slightly bent inward to guide the guide surface 24. Press it down. As a result, the sliding member 21 is slidably supported with respect to the guide member 19 while maintaining a fixed posture. Further, when the operating lever 18 is gripped and the sliding member 21 is moved, a click feeling is transmitted to the fingertip gripping the operating lever 18 by the vertical rib 26.

A through hole 34 is formed at the center of the operation lever 18, and an operation button 36 of a switch 35 is inserted into the through hole 34. Further, the above-mentioned cover member 22 is inserted around the operation lever 18. The cover member 22 moves together with the sliding member 21.

FIG. 7 shows the temperature control device viewed from the bottom of the guard 16. The sliding member 21 is fixed to the guard 16 by means of screws 37 inside the notch 17 of the guard 16. The guide groove 23 extends along the inner surface of the upper edge of the cutout portion 17 (see FIG. 3).

Further, the rack 31 of the sliding member 21 is engaged with the pinion 39 of the temperature adjusting rod 38, and the cover member 22 closes the notch 17 from the back surface thereof.

After these members are incorporated and electrical wiring is completed (see FIG. 9), the bottom plate 13 is fixed to the bottom surface of the guard 16 (see FIG. 8).

The temperature control device of the embodiment is as described above, and as shown in FIG. 1, when the operation lever 18 protruding from the notch portion 17 of the guard 16 is moved left and right, the sliding member 21 slides. The claw 27 slides in the guide groove 23 of the guide member 19. At this time, the front surface side of the sliding member 21 is restricted by the engagement of the sliding claw 27 and the guide groove 23, so that the posture of the sliding member 21 is properly held. Further, since the rear surface side of the sliding member 21 is regulated by the engagement of the elastic piece 28 and the guide surface 24, the posture of the sliding member 21 is held more correctly.

Further, since the elastic piece 28 slides on the minute vertical ribs 26 of the guide surface 24 as the sliding member 21 moves, a click feeling is given to the fingertip holding the operation lever 18. At the same time, the pinion 39 meshing with the rack 31 rotates, and the temperature adjusting rod 38 moves up or down in accordance with the rotation, and the set temperature is changed by changing the contact interval of the bimetal 40 (see FIG. 2). change.

[0025]

[Effect of device]

 As described above, according to the present invention, the guide groove of the guide member is formed in the horizontal direction, and the sliding claw of the sliding member is hung and fitted in the guide groove, so that the cost can be reduced by reducing the number of parts. In addition, the magnitude of the sliding resistance acting on the sliding member does not vary and can be maintained uniformly.
