Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a cooking appliance such as a toaster oven.

[Technical background of the invention]

BACKGROUND ART Conventionally, toaster ovens and the like have been proposed in which when baking bread and the like in succession, the heating time for the first and second cooking times is different, thereby making it possible to bake the bread with the same brown color.

As shown in FIGS. 1 and 2, this device is equipped with a mechanical timer 1 that turns on and off electricity to the cooking heater, and a control means (not shown) that extends only the first baking time. Also provided is a browning adjustment mechanism 2 that interlocks and winds up the timer 1. The browning adjustment mechanism 2 is configured as follows. That is, a browning set table 5 with a set knob 4 attached thereto is attached to a guide shaft 3 provided along the vertical direction so as to be movable up and down, and a timer shaft 1
An interlocking arm 6 is fixed to a, the distal end engaging part 6a of this arm 6 is engaged with the arm engaging part 5a of the table 5, and a browning adjustment knob 7 is attached directly below the table 5. A color adjustment cam 8 is provided, and the above-mentioned stand 5
is always urged upward by a spring 9. In addition,
10 in the figure is a timer knob.

This mechanism 2 first rotates the baking color adjustment cam 8 using the baking color display A as a guide, and then rotates the baking color setting table 5.
When the cam 8 is pressed down until it stops, the timer 1 can be wound up via the interlocking arm 6 by the engagement of both the engaging parts 5a and 6a.
The amount of winding of the timer 1 corresponds to the distance B between the setting table 5 and the cam 8, which is adjusted by the rotation of the cam 8. In addition,
The browning setting table 5 is pulled up by a spring 9 as the pressure on the setting knob 4 is released. By pushing down the set knob 4 of this mechanism 2 each time the bread is baked, it is possible to obtain bread of the same brown color.

[Problems with background technology]

However, according to the conventional browning adjustment mechanism 2, since the browning set table 5 directly hits the browning adjustment cam 8,
Since this structure determines the winding amount of the timer 1, these must be placed facing each other in the vertical direction. For this reason, the degree of freedom in design is low, and
When the browning adjustment cam 8 is made larger, the height of the browning adjustment mechanism 2 becomes larger, and this mechanism 2 increases in size.
This leads to an increase in the size of the control device including the above, and it becomes difficult to fit the control device into the limited space inside the cooking device housing. Therefore, in the end, a small browning adjustment cam 8 has to be used, and the winding amount of the timer 1 is also limited to a small value.

[Purpose of invention]

Therefore, the purpose of the present invention is to provide a cooking appliance that can increase the degree of freedom in designing the browning adjustment mechanism without increasing the height of the mechanism, and can also use a large browning adjustment cam. It is about providing.

[Summary of the idea]

The present invention is equipped with a browning adjustment mechanism that winds up in conjunction with a mechanical timer that turns on and off electricity to a cooking heater, and this adjustment mechanism is installed on a guide shaft installed along the vertical direction. A browning set table is supported so as to be able to move up and down in conjunction with the timer, and a set knob is attached to this set table, and a browning adjustment cam is rotatably mounted below the browning set table. Further, a set table stopper having a cam follower arm that engages with the cam surface of the browning adjustment cam is supported below the browning set table so as to be movable up and down on the guide shaft, and a pointer is attached to the set table stopper. This cooking device is characterized in that it is formed by providing a section.With this configuration, the cooking device achieves the intended purpose.

[Example of idea]

An embodiment of the present invention will be described below with reference to FIGS. 3 to 11.

21 in Figure 3 is the cooker housing, and on the front side,
A door 22 with a see-through window is installed so that it can be opened and closed, and an operation panel 2 is installed adjacent to the door 22.
3 is provided. The door 22 opens and closes the inside of the refrigerator inside the housing 21, and in conjunction with the opening and closing of the door 22, a cooking grate (not shown) housed inside the refrigerator is pushed out and retracted.

Inside the casing 21, a control device 24 is provided adjacent to the interior of the refrigerator and on the back side of the panel 23. This device 24 controls upper and lower cooking heaters 25 (see FIG. 4) provided in the refrigerator, and also includes a timer 26, a browning adjustment mechanism 27, and a browning adjustment mechanism 27 as illustrated in FIGS. Timer lock mechanism 2
8 etc., and each part will be explained in detail below.

29 in the figure is a device board made of sheet metal, and the operation panel 2
It can be installed by screwing it onto the back side of 3. A timer 26 is screwed to the upper back surface of this board 29. The timer 26 is a mainspring,
It is a mechanical type having a built-in gear, balance, etc. (none of which are shown), and has a bell 30, a bell hammer 31, etc. that notify the completion of rewinding (timer operation). Furthermore, the timer 26 is closed at the same time as the mainspring is wound by a switch 32 (see Fig. 4).
It also has a locking member 33. The lock member 33 is movable and, when pushed in, locks the balance wheel and the like to stop the rewinding operation of the timer (hereinafter referred to as timer lock). As shown in FIGS. 8 to 10, an operating shaft 35 is fitted onto the shaft 34 of the timer 26, and a pin 36 is provided in a protruding manner. The pin 36 is inserted through a groove 37 of the operating shaft 35 in order to rotate the operating shaft 35 together.
A timer knob 38 is attached to the front portion of the operating shaft 35 that projects outside the operating panel 23.

The browning adjustment mechanism 27 has the configuration shown in FIGS. 5 to 7. That is, the device board 29 is provided with a guide shaft 39 along the vertical direction.
A baking set table 40 for winding up the timer 26 in conjunction with the above-mentioned timer 26 is supported at 9 so as to be movable up and down. The interlocking structure between the setting table 40 and the timer 26 is as follows. An interlocking sleeve 41 made of synthetic resin is rotatably fitted onto the operating shaft 35 . This sleeve 41 is integrally formed with a pin engagement protrusion 42 and an arm 44 having an engagement hole 43 made of an elongated hole. The engagement pin 45 is engaged. The protrusion 42 is provided on the unwinding side with respect to the pin 36. Therefore, when the baking set table 40 is lowered, the interlocking sleeve 41 is rotated at the same time, and the timer 26 is wound up by the engagement of the protrusion 42 with the pin 36. Of course, if the protrusion 42 and the pin 36 are engaged, the browning set table 40 will be raised in conjunction with the rewinding of the timer 26, and if only the timer knob 38 is turned, the pin 36 will be raised. moves away from the protrusion 42, so the baking set table 40 is not interlocked. Further, a browning adjustment cam 46 is rotatably provided below the browning set table 40 so as to be off the movement trajectory of the table 40. This embodiment shows a case where the cam 46 is attached to a rearward-facing cam attaching portion 29a of the device board 29. This cam 4
6 is made of synthetic resin, and its cam surface has an uneven shape. The cam shaft 47 passes through one side wall 21a of the housing 21, and a browning adjustment knob 48 is attached to the penetrating portion. Furthermore, below the baking setting table 40, a sheet metal setting table stopper 50 having a cam follower arm 49 that engages with the cam surface of the cam 46 is supported by the guide shaft 39 so as to be movable up and down. The cam follower arm 49 is formed by connecting a horizontal engaging end 49a to the upper end of the upwardly facing part, and the engaging end 49a has a tapered shape such as a V shape and engages with the unevenness of the cam surface. I'm starting to do that. It goes without saying that the cam shaft 47 is disposed vertically below the engagement portion between the cam surface and the engagement end portion 49a. The engagement between the tapered engagement end 49a and the unevenness of the cam surface serves to prevent the cam 46 from being inadvertently rotated. The set table stopper 50 is always urged downward by a spring 51. The set table stopper 50 is provided with a pointer portion 52. Pointer section 5
2 may be provided integrally with the stopper 50, but
This embodiment shows a case where a separate piece is provided by screwing. This pointer section 52 is connected to the substrate 2
It is vertically movably inserted into a gap formed between a colored base plate 54 that is fastened together with screws 53 to the lower front surface of the base plate 9 and a transparent plate 55 that covers the front surface. The protruding portion of the transparent plate 55 is exposed flush with the surface of the operation panel 23, and the surface of the panel 23 is provided next to the transparent plate 55 to indicate the degree of baking, such as “light,” “medium,” and “dark.” ” is attached. Further, a setting knob 57 is attached to a knob mounting portion 40a of the browning setting table 40 that protrudes outside the operation panel 23. The knob 57 has a flat tip, for example, or has an alignment protrusion (not shown) on one side.
Furthermore, when the knob 57 is pressed down until the baking set table 40 hits the set table stopper 50 and stops, the flat tip or the protrusion moves toward the pointer portion 5.
It is attached to the baking set table 40 at the same height position as 2. By matching the position with the pointer portion 52, the user can confirm the baking setting, which is useful for preventing misuse. In addition,
Reference numeral 40b in FIGS. 5 to 7 is an arm portion for stabilizing the raising and lowering of the baking set table 40.

The timer lock mechanism 28 is shown in FIGS. 5 and 11, and includes a bimetal 58 of high temperature operation type, a heater 59 provided near this, a spring 60 that biases the bimetal 58, and an adjusting screw 61. It is formed from. The bimetal 58 has a control part 58a made of a sheet metal at one end, and a mounting part 58b at the other end.
It is pivoted on 9a. The control section 58a of the bimetal 58 always pushes the locking member 33 under the biasing force of the spring 60. Due to the above-mentioned high-temperature operation type, the first bread baking time is the total time of the timer lock time and the timer operation time, and the second consecutive bread baking time is the timer operation time only. This allows for continuous cooking with even browning.

For example, when baking bread continuously in the toaster oven, first put the first bread into the oven and then operate the browning adjustment knob 48 to control the browning adjustment cam 4.
Turn 6. As a result, the distance between the engaging end 49a of the cam follower arm 49 of the set table stopper 50, which is always pressed against the cam surface by the spring 51, and the cam shaft 47 changes, and at the same time, the set table stopper 5
0 rises or falls along the guide axis 39. Note that the maximum displacement of the setting table stopper 50 is the same as the dimension L in FIG. Therefore, since the pointer section 52 also moves up and down, the user can adjust the desired browning color using the pointer section 52 and the browning color display 56 as a guide. Thereafter, the baking set table 40 is pushed down along the guide shaft 39 via the set knob 57 until its lower end abuts the set table stopper 50 and stops. When this depression is completed, the height positions of the pointer portion 52 and the set knob 57 match. Then, in conjunction with the baking setting table 40, the timer 26 and the timer knob 38 are wound up through the interlocking sleeve 41 by an angle corresponding to the amount of descent thereof. This results in
The switch 32 of the timer 26 is turned on, energizing the cooking heater 25 and the heater 59, and the first bread baking is started. The first time baking continues after the timer lock mechanism 28 releases the timer lock until the timer operation is completed.
You can heat up the entire cold toaster oven and bake it to a desired color. Next, after putting the bread to be baked for the second time into the oven, the browning setting table 40 is pushed down again via the setting knob 57 until it hits the setting table stopper 50. Then, the timer 26 interlocks and winds up the same amount as the first time, but this time the bimetal 58 has already been deformed by residual heat and is not locked, so the timer 26
Immediately starts the timer operation, and the second bread is baked in a shorter time than the first time. This allows you to bake the bread the second time with the same color as the first time. As described above, the user does not have to go through the trouble of resetting the time using the timer knob 38 every time he bakes bread, and once he has operated the browning adjustment knob 48, he can perform a simple setting operation by simply pressing down on the set knob 57. You can get bread with the same brown color.

According to the above configuration, the baking setting table 4
A set stopper 5 is attached to the guide shaft 39 on which the 0 moves up and down.
The cam driven arm 49 of this stopper 50 is engaged with the cam surface of the browning adjustment cam 46, and the height position of the stopper 50 is changed by this cam 46 to adjust the browning color. Therefore, it is not necessary to provide the browning adjustment cam 46 directly below the browning setting table 40 so that the browning setting table 40 can come into contact therewith. In other words, by extending the arm 49, the cam 46 can be placed in front or on the side, avoiding the movement path of the baking set table 40, so there is a high degree of freedom in design. The browning adjustment cam 46 can be made larger without increasing the height of the cam 46.
By increasing the size, the vertical stroke of the stopper 50 indicated by the dimension L, or in other words, the winding amount of the timer 26 can be increased.
Therefore, it is possible to increase the range of adjustment of the browning color.

Although the above-mentioned embodiment is constructed as described above, in carrying out the present invention, a mechanical timer, a guide shaft, a browning setting table, a setting knob, and a browning adjustment may be used as long as it does not contradict the gist of the invention. Specific structures of the cam, set stopper, cam follower arm, pointer, etc.
Of course, the shape, position, material, etc. are not limited to the one embodiment described above, and can be configured and implemented in various ways.

[Effect of idea]

Since the present invention described above has the configuration described in the above-mentioned utility model registration claims, it is necessary to provide a baking color adjusting cam directly below the baking set table which can be raised and lowered so that this table can come into contact with it. It has great practical effects, such as a high degree of freedom in design and the ability to enlarge the browning adjustment range by increasing the size of the browning adjustment cam without increasing the height of the browning adjustment mechanism. be.
