Description

[Detailed Description of the Invention] The present invention relates to a cooking device for cooking food materials, and more particularly to a timer attachment mechanism.

Generally, a cooking device such as a toaster oven as shown in FIGS. 1 to 3 is used. This toaster oven houses a heating element and a timer operating element therein to heat food materials. Further, this toaster oven has an opening/closing door 2 and a timer display mechanism 3 (hereinafter referred to as the display mechanism) on the front of the case 1, and a timer operation knob 4 connected to the timer operating body is provided on the side. ing. By rotating the timer operating knob 4, a built-in timer operating body is activated, and the heating element is energized for the time set by the timer operating body to heat the food material. The display mechanism 3 displays the cooking time set by the timer operating body on the display band 3A, and also displays the cooking time set by the timer operating body on the display band 3A.
A displays the remaining cooking time in conjunction with the timer operating body. This conventional display mechanism 3 was constructed as follows. That is, a groove 3C is provided in the widthwise center of the display substrate 3B along the vertical direction, and the lower end of the groove 3C communicates with the back surface of the display substrate 3B to form an insertion opening 3D. Further, a transparent plate 3E is closely attached to the front side of the display substrate 3B, and the groove portion 3C is attached to the transparent plate 3E.
The display band passage 5 is formed by closing the opening surface of the display band passage 5. A transparent film 3F on which a scale indicating the cooking time is printed by means of vapor deposition or the like is adhered to the surface of the transparent plate 3E. Further, the display substrate 3B, the transparent plate 3E, and the transparent film 3F are integrally formed by a fixing member 3G, and are fixed to the front surface of the case 1. The display band 3A is inserted into a display band passage 5 formed by a display substrate 3B and a transparent plate 3E, and is wound around a roller 3H. This roller 3H is housed in a roller cover 3J having a guide path 3I for guiding the display band 3A to the display band passage 5. This roller cover 3J is the bracket 3
It is attached to case 1 via K. The roller 3H is mounted on a common shaft between the timer operation body and the timer operation knob 4, and inserts the display band 3A into the display band passage 5 in response to rotation of the timer operation knob 4. . The timer section is constructed in this manner, and as described above, this timer section is mounted inside the case 1 via the bracket 3K to constitute a timer mounting mechanism. and,
On the front side of the display mechanism 3, it is possible to visually observe through the transparent plate 3E and the transparent film 3F that the display band 3A is raised in the display band passage 5 according to the amount of rotation of the timer operation knob 4, The timer operating body can be set at any position on the scale. After setting the timer, the timer operating body rotates the roller 3H and the timer operation knob 4 in the direction of winding up the display band 3A onto the roller 3H as time passes, and after a predetermined cooking time has elapsed, the display band 3A is It is wound around the roller 3H so as to indicate the 0 position on the scale.

As described above, the conventional timer mounting mechanism configured as described above has the following problems. In such a mounting mechanism, the roller 3H on which the display band 3A is wound and the timer operating body are housed in the roller cover 3J. The roller cover 3J is attached to the case 1 with a bracket 3K.
Therefore, the external force applied to the timer portion when the timer operating knob 4 is rotated is received only by the bracket 3K. For this reason, the method of attaching the entire timer section to the case 1 is unstable and there is a drawback that rigidity is insufficient. Therefore, when the timer operation knob 4 is rotated, the relative position between the timer section and the display board changes, and the display band 3A cannot display accurately.
The display band 3A moves in the width direction within the display band guide groove 3C, and the display band 3A enters the gap between the display substrate 3B and the transparent plate 3E, and the display band 3A moves to the display band guide groove 3C.
There was also a problem where it was impossible to move up and down inside.

The present invention was developed in consideration of the above circumstances, and its purpose is to provide an integral protrusion on the roller cover to absorb the external force applied to the timer part when the timer knob is rotated. It is an object of the present invention to provide a timer mounting mechanism for a cooking appliance in which a timer part is firmly attached to a case by being supported at multiple points by the above-mentioned protruding parts.

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 4 shows a timer mounting mechanism for a toaster oven according to an embodiment of the present invention, and numeral 1 in the figure is a case. A display substrate 6 and a transparent scale plate 7 are provided on the front side of the case 1. A display band guide groove 6A is provided in the center of the display substrate 6 along the vertical direction.
(hereinafter referred to as a guide groove) is provided, and a transparent scale plate 7 is bonded to the display substrate 6 by means such as welding. Further, a timer section 8 is provided on the back side of the case 1, and this timer section 8 is composed of a timer operating body 8A, a roller 8B, a roller cover 8C, and a timer knob 8D. The timer operating body 8A, roller 8B, and timer knob 8D are rotatably attached as one body. A display strip 3A formed into a thin strip of a flexible material such as polyethylene is wound around the roller 8B. This display band 3A is led out from the guide portion 8E of the roller cover 8C to the guide groove 6A of the display substrate 6, and is configured to move up and down the guide groove 6A in accordance with the movement of the roller portion 8B. Also, this roller cover is connected to case 1 via bracket 8I.
It has an integrally molded protrusion 8F. This protrusion 8F is formed so as to come into contact with the inner side surface of the case 1.

The mounting mechanism described above is constructed as shown in FIG. In such a mounting mechanism, the external force applied to the timer section 8 is applied to the bracket 8I and the protruding section 8.
It is configured to be supported at multiple points at F. Therefore, the relative position of the timer section 8 with respect to the display substrate 6 is not changed by external force, and the display band 3A can perform accurate display.

The present invention is applicable not only to the timer attachment mechanism of a toaster oven as described above, but also to various cooking appliances having a built-in timer.

As explained above, the timer mounting mechanism of the cooker according to the present invention includes a timer operating body having a rotation axis,
A cylindrical display band collecting roller is provided coaxially with the timer operating body and rotates together with the timer operating body, and the display band is wound around this roller and is placed on the front side of the case of the cooking appliance by the rotation of the timer operating body. a roller cover that is attached to the inner surface of the case via a bracket, integrally having a thin timer display band for displaying a timer, and a protrusion that accommodates the timer operating body and the roller and comes into contact with the inner surface of the case of the cooking appliance; The timer operating knob is attached to a rotating shaft led out of the case of the timer operating body. Therefore, the external force applied to the timer part when the timer knob is rotated is supported at multiple points by the bracket and the protruding part, and the timer part can be firmly attached to the case, allowing the timer display band to move within the display band guide groove. The effects are great, such as being able to display accurate timer information without having to do anything.
