Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a time limit setting device for toast roasting such as a toaster oven.

Conventional structure and its problems Conventionally, when toasting is performed in a toaster oven, etc., especially when toasting is performed continuously, the heat is absorbed by the toaster oven casing during the first toasting. Since the toasting time was set long and the toaster oven housing was preheated from the second time onward, it was necessary to set the toasting time short to keep the toast browning constant during continuous baking. . However, the difference in roasting time between the first and second roasting times is not always constant and varies depending on the length of time the roasting time is left between the first and second roasting times. It was practically impossible to set the roasting time taking these factors into consideration. Therefore, a timer device that can set a time limit by rotating the shaft, etc., has a bimetal that changes in response to heating and cooling of the casing to control the roasting time. A device was thought of. However, in this case, it is troublesome to rotate the axis of the timer device each time in order to align it with the time scale, and there is a need for an effective means due to lack of accuracy.

Purpose of the invention The present invention aims to eliminate the above-mentioned conventional drawbacks, improve the operability of time limit setting, and enable reliable time limit setting.

Structure of the Invention In order to achieve the above object, the present invention includes a timer device equipped with a driving source, an arm attached to the shaft of the timer device, and a shaft of the timer device that comes into contact with the arm and is pressed down by a downward operation. The apparatus includes an elevating member to be rotated, and a cam whose radius changes stepwise in the rotation direction, and a cam that sets the amount of movement of the elevating member and changes the amount of rotation of the shaft of the timer device according to the change in radius. According to this configuration, the axis of the timer device is rotated by pushing down the lifting member, so the operation is extremely easy, and the movement of the lifting member can be set by a cam that can be set arbitrarily. As a result, once a predetermined time is set, it is possible to set a reliable time limit without any variation. Moreover, if you want to adjust the toast color to your preference, you can adjust the elevating and lowering member by moving the cam. This can be easily achieved by changing the amount of movement and changing the set time.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings.

In the figure, 1 is a unit stand, and this unit stand 1 includes a timer device 2 equipped with a drive source, a speed change mechanism, a power switch, an alarm mechanism, etc., and an arm 4 that rotates a shaft 3 of this timer device 2. A guide rod 8 that slides the elevating member 7 having a contact portion 6 that contacts the sliding portion 5, a spring 9 that urges the elevating member 7 in the return direction, and a receiver that receives the abutting portion 10 of the elevating member 7. A cam 12 having a portion 11 is mounted. The cam 12 is rotatably supported by a shaft 13, and an elevating knob 14 is attached to the elevating member 7.

In the above configuration, when the operating knob 14 is lowered against the spring force of the spring 9, the contact portion 6 of the elevating member 7 contacts the sliding portion 5 of the arm 4 and pushes the arm 4 down. As a result, the shaft 3 of the timer device 2 is rotated, and the contact portion 1 of the elevating member 7 is rotated.
0 hits the receiving portion 11 of the cam 12, the lowering of the elevating member 7 is regulated and a predetermined time limit is set. In this case, if the cam 12 is rotated in advance as required, the amount of movement of the elevating member 7 can be changed, thereby making it possible to make the time limit setting variable. Furthermore, when the operation of the operating knob 14 is completed, the elevating member 7 returns to its original position by the action of the spring 9, so there is no restriction on the return of the arm 4 when the timer device 2 returns. Therefore, there is no need for the timer to stop. Further, since the receiving portion 11 of the cam 12 is configured in a stepped shape, it is possible to eliminate deviations in the set time due to the escape of the cam 12 based on the contact force of the elevating member 7.

Effects of the invention As described above, the time setting device of the present invention rotates the axis of the timer device by pressing down the lifting member, so the operation is extremely easy, and the amount of movement of the lifting member can be controlled arbitrarily. Since we are trying to receive and regulate it with a cam that can be set to
Once a predetermined time is set, it is possible to set a reliable time without any variation, and if you want to adjust the toast color to your preference, you can change the set time by changing the amount of movement of the lifting member by moving the cam. This can be easily achieved by
