Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a timer used in electric cooking appliances and the like.

Conventional structure and problems In recent years, motors have been equipped with a drive section, a transmission section, a switch section, a notification section, etc., and are configured to start and shut off energization and notify the completion of a set time by rotating the shaft. Timing devices are widely used in electric cooking appliances such as ovens, microwave ovens, and toaster ovens.

On the other hand, among electric cooking appliances incorporating the timer device, a toaster oven is the most popular electric cooking appliance capable of roasting toast. This includes toasts of various thicknesses, hot dogs, and even gratin.

It is rapidly becoming popular because it can be used to cook a wide range of dishes such as kutsky and grilled rice cakes, and is convenient and inexpensive. However, the reality is that most of these toaster ovens are used for roasting toast, and there is a strong desire to improve the toast roasting function.

In other words, in a toaster oven, especially when roasting toast continuously, in order to make the toast the same color, it is necessary to set the timer setting device for the first and subsequent toasts based on the heating state of the container. I had to change because of the difference. Moreover, it is necessary to change the setting time in relation to the interval of standing time between finishing roasting and moving on to the next roasting, but it is impossible to know the optimal time in total.
In the past, it was extremely inconvenient in practice, such as having to set the time limit of a time limit setting device empirically.

In order to solve the above problem, it is necessary to use in parallel a time limit setting device for toast roasting and another time limit setting device that can set cooking times other than toast (longer than toast time). In view of the low cost of toaster ovens, a more rational method was sought, and a method was required to solve the above problems by effectively utilizing the timer function of one toaster oven.

Purpose of the Invention In view of the above-mentioned conventional problems, the present invention is to achieve two different time-limiting functions with one time-limiting device, and to clearly appeal visually which of the two time-limiting functions is functioning. The purpose is to make it possible.

Structure of the Invention In order to achieve the above object, the timer of the present invention includes a timer setting device having an operation member that can directly set a timer as desired, and a correction device for temporarily stopping the operation of the timer setting device. and a connecting means for arbitrarily making this correction device unrelated to the time limit setting device, and an indirect time limit setting device having an operating member that indirectly operates the time limit setting device to set a time limit. When the time limit is set by the indirect time limit setting device, the operating member is provided with an intermediate stop means that temporarily stops the operation member halfway within its operation range and returns to the initial position at the same time as the time limit setting device completes the time limit setting device. in,
According to this configuration, the time limit can be set by directly operating the time limit setting device using one time limit device, and
The indirect time setting device having the operating member enables another time limit setting via the correction device, and furthermore, when the indirect time setting device operates the timer, the operating member is temporarily stopped halfway within the operating range. By looking at this, the user can easily confirm that the indirect timer is operating in this state.This allows the user to clearly see which of the two timer functions is operating. This has the effect of being able to appeal to people.

By inserting it, it is possible to prevent runout. Furthermore, this elevating table 2o has a mounting piece 24 for attaching the elevating table 123, an engaging claw 26 that engages with a hook to be described later, and an operating boss 11 of the time limit lever 1o and the elevating table 2Q that come into contact and slide when setting a time limit. Moving action part 2
6, and an operating claw 28 that comes into contact with an operating lever to be described later via a sleeve 27 at a certain position.

Reference numeral 29 denotes a hook, one end of which is in contact with the switch button 3 of the time setting device 1, and the other end engaged with the engagement claw 25 of the lifting platform 20, so that the lifting platform 2
It is provided with a stop claw 30 that temporarily stops the upward movement of o. The hook 29 is rotatably supported by a timer 31, and is biased by a hook spring 32 in a direction such that one end of the hook 29 is always in contact with the switch button 3 of the time setting device 1. It swings in relation to the movement of the switch button 3 of the time limit setting device 1 into and out.

Reference numeral 33 designates an operating lever, and a thermally responsive element 36 having an insulator 34 fixed to its tip is fixed to one end of the operating lever 33 via an embedded metal fitting 36, and an elevator platform 20 is attached to the other end of the operating lever 33.
It is provided with an inclined part 38 that comes into sliding contact with the operating claw 28 of the
Furthermore, it is rotatably supported by the timer 31.

39 is a control lever, and as shown in FIGS. 7 and 8, this control lever 39 has a contact portion 40 that contacts the contact portion 37 of the operating lever 33, and a tip of the stop piece 5 of the time setting device 1. 41 and the operating claw 2 of the lifting platform 20.
8 and an inclined portion 43 that comes into sliding contact with the timer 8, and is rotatably supported by a timer 31. 44 is a lever that biases the operating lever 33 and the control lever 39 in one direction; 46 is a correction device using a heat-responsive self-heating bimetal or the like, which is fixed to the substrate 46 via an electrical insulator; Furthermore, the board 46 is fixed to one timer 31 with screws or the like. Further, the correction device 45 has a housing (not shown).
, for example, is displaced downward by heating in the cooking chamber of a toaster oven, etc., and is coldly supported by a timer unit 31 with a clip spring 50, and controls the amount of descent of the lifting table 20 by operating an adjustment knob 49. , adjust the set time of the time limit setting device 1. Further, the operation lever 33 and the control lever 39 constitute a connecting means, and the lifting platform 20, the time limit lever 10, and the lifting knob 23 constitute an indirect time setting device, and the time limit setting device 1 and the hook 29 are connected in the middle. Stop means are configured.

The mounting bracket 18, the timer unit 31, and the board 46 are still firmly connected to each other with screws or the like.

The operation in the above configuration will be explained. The states shown in FIGS. 1 and 7 are states in which the time limit setting device 1 is OFF. First, in this state, the lifting platform 2o, which is urged upward by the lifting spring 21, is located at the highest position, so the operating pawl 28 of the lifting platform 2o comes into contact with the inclined portion 38 of the operating lever 33. As a result, the operation lever 33 is rotated in the clockwise rotation direction and the connection with the control lever 39 is released, so that the time limit setting device 10 and the clock 4 are not regulated by the control lever 39. ing. In this state, in order to cook something other than toast that requires a relatively long cooking time, if you directly turn the time setting device 1 using the time limit knob 9, the time limit can be set as desired since the Tenfu 4 is in a free state. Electricity is supplied for the set time period and cooking is performed. During this energization, the tip 47 of the correction device 45 using bimetal is displaced downward in connection with the heating of the housing.
Since this direction is the direction in which the operating lever 33 is further pushed down, the relationship between the operating lever 33 and the control lever 39 remains as it is, and no external regulation is applied to the balance 4 of the time setting device 1.

Next, when toasting, first turn the lift knob 23.
is operated to push the elevator platform 20 down to the position where the cam 48 restricts its descent. As a result, a predetermined time limit is set in the time limit setting device 1 via the time limit lever 10, and at the same time, the switch section becomes energized, and the correction device 46 starts to deform downward. At the same time as this, the operating claw 28 of the lifting platform 20 hits the inclined portion 43 of the control lever 39, causing the control lever 39 to rotate clockwise against the biasing force of the lever spring 44, and the operating claw 28 Top 5 of control lever 39
1, the contact portion 37 of the operating lever 33 and the contact portion 40 of the control lever 39 engage with each other as shown in FIG. 8 due to the urging force of the lever spring 44, and the control lever 3
The control piece 42 of 9 displaces the stop piece 6 of the time setting device 1 and brings it into contact with the crown 4, thereby bringing the timed operation of the time setting device 1 into a temporary halt state. Furthermore, at the same time that the switch section of the time limit setting device 1 described above becomes energized, the switch button 3 is displaced as shown by the imaginary line in FIG.
The hook 29 in contact with the switch button 3 rotates in the counterclockwise direction against the biasing force of the hook spring 32, and as the elevator platform 20, which had been pushed down, rises, the engaging claw 29
5 and the stop claw 30 of the hook 29 come into contact with each other, and the lifting platform 20
stop the rise midway.

In the above-mentioned state, although the power is already on, the movement of the crown 4 of the time setting device 1 is stopped by the stop piece 5, so that no time setting operation is performed.

However, since the tip 47 of the correction device 45 displaces downward over time, the operating lever 33 is rotated in the clockwise rotation direction via the insulator 34 against the biasing force of the lever spring 44. At the same time as the control lever 39 is disengaged from the contact portion 40, the control lever 39 is rotated in the counterclockwise rotation direction by the biasing force of the lever spring 44, and as a result, the time limit setting device 1 is rotated. Since the external force on the stop piece 5 is no longer applied and the regulating force of the crown 4 is also no longer present, the timed operation is started from this point. In this state, the positions of the operating lever 33 and the control lever 39 have been changed as shown in FIG. 7, but the lifting platform 20 and the hook 29 remain in the position shown in FIG.

Then, at the same time that the timed operation of the timer setting device 1 is completed after a predetermined period of time has elapsed, the switch section changes from ON to OFF state and a notification sound is emitted and a bell is struck), and the switch button 3 returns to its original state. Since the hook 29 also returns to the right to the state shown in FIG. 7 due to the biasing force of the hook spring 32, the connection with the lifting table 20 is released, and as a result, the lifting table 20 rises to the highest level and cooking is completed. do. In other words,
In this operation, the cooking time for the first batch is the total time of the time during which the operating lever 33 stops the movement of the top 4 and the time during which the time setting device 1 performs the timed operation. Furthermore, when roasting toast continuously, the bimetal of the correction device 45 acts in accordance with the pause time from the completion of the previous roast to the start of the next roast, and controls the stop time of the Tenfu 4. , the toast color can be kept constant. Furthermore, since the lifting table 20 is stopped midway within its movement range during toast roasting, the user can check the position of the lifting knob 23 to determine whether this state causes the correction device 45 to function. In other words, it is easy to confirm that it is toast roasted, and as a result,
It is possible to clearly visually appeal to the user whether one of the two timed functions is functioning.

In the above-mentioned embodiment, the position of the lift knob 23 visually indicates that the correction device 45 is operating in a timed operation (i.e., toast roasting); Enter”.

The display frame 52 (Fig. 1) displaying the words "OFF" etc. is fixed, and the display corresponding to the timed operation can be seen from the outside at the two positions where the lifting platform 2o stops (during toast roasting and when it is OFF). If it can be done, even greater effects can be obtained.

Effects of the Invention As described above, the present invention includes a correction device for temporarily stopping the operation of a time limit setting device, and a connecting means for arbitrarily associating or not relating this correction device to the time limit setting device. Because of this, different timer functions can be achieved with one timer, which is very advantageous in terms of cost. Since the indirect time setting device, which has an operating member for indirectly operating the time setting device to set the time limit, is stopped at two different positions, it is difficult to operate the time limit setting device in either of the two time functions. It allows you to visually tell what is there, and its practical effects are great.
