  In the electric cookers described in Patent Documents 1 and 2, a relay member and a lever that transmit the operation of the container being mounted to the detection unit are provided inside the container base or inside the container base. It is a structure that transmits the operation of the container being mounted using the inside of the table to the detection unit provided in the main body. Therefore, in the electric cookers described in Patent Documents 1 and 2, the relay member and the lever must be arranged inside the container base, but the relay member and the lever are movable in the vertical direction. As a result, it is difficult to secure a large installation space that is long in the vertical direction of the relay member and lever in a limited space inside the container base. It was. In addition, preparation members and the like are also arranged inside the container stand, and relay members and levers must be disposed while avoiding interference with these members, and the operation of the container being mounted is transmitted. The structure was complicated. In addition, when placing the relay member or lever inside the container base, not only the interference with the adjustment member etc., but also the relay member and lever must be provided so that the food in the container does not leak outside. In this respect, the structure is complicated.

  The electric cooker described in Patent Document 3 includes an operating rod that transmits an operation to the detection unit when the lid is attached. This operating rod is a handle that protrudes outward in the radial direction of the container. It is provided inside the part. Therefore, it is considered that when the working rod is provided in the container, it is not necessary to consider interference with a preparation member or the like provided in the container, and the structure can be simplified. However, as described above, the electric cooking device described in Patent Document 3 is different from the electric cooking devices described in Patent Documents 1 and 2 in that a container base is not provided and a preparation member is provided in the container itself. The container is directly attached to the main body. Therefore, when cleaning the preparation member, the preparation member must be removed from the inside of the container, and it is difficult to remove the preparation member, so it is difficult to clean the preparation member. It has become. Moreover, since the container is mounted on the main body as it is, if the container is not mounted at an appropriate position, the position of the container becomes unstable, and it is impossible to detect whether the lid is mounted or not. The container must be attached to the main body in a state where the container is aligned, and the work of attaching the container to the main body is complicated.

  The present invention has been made paying attention to such a point, and the purpose thereof is to easily clean the preparation member and to easily attach the container to the main body while the container and the lid are attached. An object of the present invention is to provide an electric cooker provided with a safety mechanism capable of simplifying the structure for transmitting the operation to the detector.

  To achieve this object, the electric cooker according to the present invention includes a main body provided with a driving means, and a detachable and attachable to the main body with the driving means in the state of being attached to the main body. A container table provided with a rotation-driven preparation member; a container that is attachable to and removable from the container table such that the preparation member is disposed therein; and a container that is removable from the container table; A detection unit that detects a container mounting state in which the container base and the container are mounted, or a lid mounting state in which the container base, the container, and the lid are mounted. A container mounting operation associated with an operation of mounting the container base and the container, or a lid mounting operation associated with an operation of mounting the lid on the mounted container. On the transmission member and the body side It is configured to be able to transmit to the detection unit via transmission between the obtained main body side transmission member, and the detection unit detects the container mounting state when the container mounting operation is transmitted, or When the lid mounting operation is transmitted, the lid mounting state is detected, and the container side transmission member and the main body side transmission member pass through the outside of the container base and the container side transmission member and the main body side transmission. It is in the point comprised so that direct transmission between members may be performed.

  According to this characteristic configuration, the container base is detachable from the main body, the container is detachable from the container base, and the lid is detachable from the container. After the container is attached and the container base and the container are integrally joined, the integrally joined thing is attached to the main body, the container base and the container are attached to the main body, and after the food is put into the attached container, the By attaching the lid to the attached container, the preparation member can be prepared by rotating the preparation member by the driving means. And the container stand is comprised by the member different from a container, As a container stand, the structure which can mount | wear with a stable attitude | position and can be easily mounted | worn with respect to a main body can be employ | adopted. Therefore, instead of attaching the container as it is, by attaching the container to the main body while being attached to the container base, the container can be attached in a stable posture, and the container base can be easily attached to the main body. Can do. And, when the container base, the container and the lid are mounted, the lid is removed from the container, the container base and the container are integrally coupled, removed from the main body, and further, the container is removed from the container base, Each of the container stand, the container, and the lid can be separated. Therefore, the container, the container table, the preparation member, the lid, and the like can be easily cleaned by performing operations such as washing the container table, the container, and the lid with water.

  Then, when the operation of mounting the container base and the container on the main body or the operation of mounting the lid on the mounted container is performed, the container mounting operation or the lid mounting operation associated with the operation is transmitted to the container side transmission member and the main body side transmission. It is transmitted to the detection unit via transmission to and from the member. Thereby, the detection part can detect a container mounting state or a lid mounting state appropriately by transmission of a container mounting operation or a lid mounting operation. Therefore, for example, in a non-detection state in which the container mounting state or the lid mounting state is not detected by the detection unit, a safety mechanism that can prohibit driving of the wrong driving unit by prohibiting driving of the driving unit. Can be provided.

  Moreover, according to the present feature configuration, since the transmission between the container side transmission member and the main body side transmission member can be directly performed between the container side transmission member and the main body side transmission member through the outside of the container base, It is not necessary to provide a transmission member or the like inside the container base. And the outside of the container base is an external space outside the container base, and the external space of the container base is effectively used as a space for performing direct transmission between the container side transmission member and the main body side transmission member. Can do. In this way, according to this characteristic configuration, it is only necessary to provide the container-side transmission member and the main body-side transmission member so that they can be transmitted directly outside the container table, that is, through the external space of the container table. It is possible to simplify the structure for transmitting the operation performed to the detection unit.

  From the above, according to the present characteristic configuration, the preparation member can be easily cleaned, and the operation that the container or the lid is attached is transmitted to the detection unit while the container can be easily attached to the main body. The electric cooker provided with the safety mechanism which can aim at simplification of the structure for doing is realizable.

  According to a further feature of the electric cooker according to the present invention, the main body comprises a main body first portion for attaching and detaching the container base, and a main body second portion projecting outside the main body first portion, The container includes a container main body capable of storing food and a handle portion projecting outside the container main body, the container-side transmission member is provided in the handle portion, and the main body-side transmission member is the main body second member. The container-side transmission member and the main body-side transmission member are configured so as to be freely contactable in a mounted state provided in the portion and with the handle portion mounted on the second main body portion.

  According to this characteristic configuration, in addition to mounting the container base on the main body, the container can be mounted in a more stable posture by mounting the handle portion on the second body portion. Since the container side transmission member provided in the handle part and the main body side transmission member provided in the main body second part are configured to be freely contactable in the mounted state where the handle part is attached to the main body second part, By attaching the handle portion to the second body part, direct transmission between the container-side transmission member and the body-side transmission member can be performed. Therefore, it is possible to appropriately perform transmission between the container side transmission member and the main body side transmission member while effectively using the handle portion and the second body portion to further simplify the configuration. .

  A further characteristic configuration of the electric cooker according to the present invention is that the position where the container side transmission member and the main body side transmission member are in contact with each other in the mounted state in which the handle portion is mounted on the second main body part. It exists in the point set above the lower end part of the said container base with which it mounts | wears.

  When the container and the container base have not been securely attached and the food is prepared, the liquid in the food in the container flows out between the container and the container base. It may accumulate in the gap between the lower end of the mounted container base and the main body. Therefore, according to this characteristic configuration, by setting the position where the container-side transmission member and the main body-side transmission member are in contact with the lower end of the container base mounted on the main body, The liquid accumulated in the gap with the main body can be prevented from reaching the position where the container side transmission member and the main body side transmission member are in contact with each other, which can adversely affect the transmission between the container side transmission member and the main body side transmission member. In addition, transmission between the container side transmission member and the main body side transmission member can be appropriately performed.

  The electric cooker according to the present invention is further characterized in that the handle portion can be guided to a position where the container side transmission member and the main body side transmission member are in contact with the main body second portion, and the main body There is a guide / liquid retention preventing portion that can prevent liquid retention around the side transmission member.

  As described above, by attaching the handle portion to the second body part, the container-side transmission member and the body-side transmission member come into contact with each other, and direct transmission is performed between the container-side transmission member and the body-side transmission member. When the handle portion is attached to the second body portion, the handle portion must be attached at an appropriate position where the container side transmission member and the main body side transmission member come into contact with each other. Therefore, according to this characteristic configuration, the handle portion can be guided to a position where the container-side transmission member and the main body-side transmission member are in contact with each other by the guide / liquid retention prevention portion. It is possible to easily attach the handle portion. In addition, the guide / liquid retention prevention part not only guides the handle part but also prevents liquid retention around the main body side transmission member, so that liquid such as water stays around the main body side transmission member. The transmission between the container side transmission member and the main body side transmission member can be appropriately performed without adversely affecting the transmission between the container side transmission member and the main body side transmission member.

  The electric cooker according to the present invention may further include a first detection unit that detects the container mounting state and a second detection unit that detects the lid mounting state as the detection unit, and the container side As the transmission member, a container-side first transmission member and a container-side second transmission member are provided, and as the main body-side transmission member, a main body-side first transmission member and a main body-side second transmission member are provided, and the container mounting The operation is configured to be freely transmitted to the first detection unit via transmission between the container side first transmission member and the main body side first transmission member, and the lid mounting operation is performed on the container side second. It is configured to be able to transmit to the second detection unit via transmission between the transmission member and the main body-side second transmission member, and the first detection unit does not detect the container mounting state or the first 2 In the non-detection state in which the lid mounting state is not detected by the detection unit, In the detection state in which the driving of the driving means is prohibited, the container mounting state is detected by the first detection unit, and the lid mounting state is detected by the second detection unit, the driving unit is driven. It is in the point which has the drive prohibition and drive permission means to permit.

  According to this characteristic configuration, the detection unit is provided with the first detection unit that detects the container mounting state and the second detection unit that detects the lid mounting state, so the detection of the container mounting state and the detection of the lid mounting state And both. The drive prohibition / drive permission means allows the drive means to be driven only when the first detection unit detects the container mounting state and the second detection unit detects the lid mounting state. In other cases, the driving of the driving means is prohibited. Therefore, the drive means is not driven only by detecting the container mounting state by the first detection unit, and in addition to the detection of the container mounting state by the first detection unit, the lid is detected by the second detection unit. The driving means is driven for the first time when the mounting state is detected. As a result, the drive means can be driven only when all of the container table, the container, and the lid are mounted, and it is possible to accurately prevent the drive means from being erroneously driven.

  The electric cooker according to the present invention is further characterized in that the main body side first transmission member and the main body side second transmission member are disposed close to the main body, and the main body side first transmission is provided. Between the member and the main body side second transmission member, at the position of the main body side first transmission member when the detection of the container mounting state is started by the first detection unit, and at the second detection unit A protrusion is provided that protrudes upward from at least one of the positions of the main body side second transmission member when the detection of the lid mounting state is started.

Therefore, the members for transmitting the container mounting operation and the lid mounting operation can be efficiently arranged at concentrated positions.
Here, there is a possibility that detection of the container mounting state or the lid mounting state may be erroneously performed when the user's finger or the like contacts the main body side first transmission member or the main body side second transmission member. As described above, by providing the drive prohibition / drive permission means, only one of the main body side first transmission member and the main body side second transmission member is erroneously operated and either the container mounting state or the lid mounting state is detected. Even if only one is detected, the driving means is not driven.
However, as described above, since the main body side first transmission member and the main body side second transmission member are disposed close to each other, the user's finger is attached to both the main body side first transmission member and the main body side second transmission member. And the like, and the main body side first transmission member and the main body side second transmission member may be erroneously operated simultaneously. Therefore, according to this feature configuration, when a protrusion is provided between the main body-side first transmission member and the main body-side second transmission member, and the protrusion detects the container mounting state at the first detector, As a configuration that protrudes upward from at least one of the position of the main body side second transmission member when the position of the main body side second transmission member is started by the position of the main body side first transmission member and the detection of the lid mounting state by the second detection unit. Therefore, it is possible to prevent both the detection of the container mounting state by the first detection unit and the detection of the lid mounting state by the second detection unit from being erroneously performed by the user's finger, and the like. It is possible to accurately prevent the driving means from being erroneously driven by the cooperative action.

As shown in FIG. 5, the lid mounting operation is configured to be freely transmitted to the second detection unit 25 through transmission between the container-side second transmission member 26b and the main body-side second transmission member 27b.

(Transmission of container mounting motion)
The container-side first transmission member 26 a is configured by a convex member that protrudes downward from the lower end portion 23 a of the handle portion 23, and is provided at the lower end portion 23 a of the handle portion 23. This container side 1st transmission member 26a is urged | biased by the position which protrudes below from the lower end part 23a of the handle | steering-wheel part 23 by 2nd urging | biasing member B2 (for example, elastic spring) (refer FIG. 3).
The main body side first transmission member 27a is formed in a lever shape that is elongated in the vertical direction in a state of extending through the bottom portion 9c of the concave upper end portion 9b in the main body second portion 9 and extending into the main body second portion 9. A first non-transmission position (see FIG. 3) in which the upper end side portion projects upward from the bottom 9c of the concave upper end portion 9b in the main body second portion 9 and a lower side than the first non-transmission position. The first transmission position (see FIG. 4) is provided so as to be movable in the vertical direction. As shown in FIG. 3, the main body side first transmission member 27a is urged to return to the first non-transmission position by an urging member (for example, an elastic spring) not shown.

The operation when the container mounting operation for mounting the handle portion 23 to the main body second portion 9 is performed from the state shown in FIG. 3 will be described.
As shown in FIG. 4, when the container mounting operation is performed, the lower end portion 23a of the handle portion 23 is mounted on the upper end portion 9b of the main body second portion 9, and at this time, the container-side first transmission member 26a is The upper end portion of the main body side first transmission member 27a is contacted. Thereby, the main body side first transmission member 27a is pressed downward to move to the first transmission position, and the container is transmitted by direct transmission between the container side first transmission member 26a and the main body side first transmission member 27a. The container mounting operation is transmitted from the 3 side to the main body 1 side.

  In this way, the container mounting operation is transmitted from the container 3 side to the main body 1 side by direct transmission between the container side first transmission member 26a and the main body side first transmission member 27a. The first transmission member 26a is provided on the handle portion 23 projecting outward from the container main body 22, and the main body-side first transmission member 27a is also provided on the main body second portion 9 projecting outward from the main body first portion 8. Therefore, direct transmission between the container-side first transmission member 26 a and the main body-side first transmission member 27 a is performed outside the container table 2, that is, in the external space of the container table 2. Therefore, even if a member for transmitting the container mounting operation from the container 3 side to the main body 1 side is not provided inside the container table 2, the outer space of the container table 2 can be used effectively, and the handle portion 23 can be connected to the container side. By simply providing the first transmission member 26a and providing the main body side first transmission member 27a in the main body second portion 9, the container mounting operation can be appropriately transmitted from the container 3 side to the main body 1 side. The structure for transmitting the container mounting operation from the side to the main body 1 side becomes simple.

(Transmission of lid mounting motion)
The container-side second transmission member 26b is formed in a lever shape that extends over the entire length in the vertical direction of the handle portion 23 while penetrating the upper end portion and the lower end portion of the handle portion 23, and is provided so as to be movable in the vertical direction. It has been. The container-side second transmission member 26b is provided so as to be movable up and down between an upper position (see FIG. 4) and a lower position (see FIG. 5) below the upper position. 3 is biased back to the upper position by a biasing member B3 (for example, an elastic spring).
The main body side second transmission member 27b is formed in a rod shape that penetrates the bottom portion 9c of the concave upper end portion 9b in the main body second portion 9 and extends into the main body second portion 9, and the upper end side portion thereof is the main body second portion. A second non-transmission position (see FIG. 4) that protrudes above the bottom 9c of the concave upper end part 9b in the two parts 9 and a second transmission position that is below the second non-transmission position (see FIG. 5). And can be moved up and down. The main body side second transmission member 27b is urged to return to the second non-transmission position by an urging member (for example, an elastic spring) (not shown).

  As described above, the lid 4 includes not only the lid first portion 4a that can freely open and close the opening of the upper end portion of the container body 22, but also the lid second portion 4b that covers the upper portion of the handle portion 23. A lid-side convex portion 28 that protrudes downward is provided on the lower surface portion of the lid second portion 4b.

The operation when the lid mounting operation for mounting the lid 4 on the container 3 is performed in the state shown in FIG. 4 will be described.
As shown in FIG. 5, when the lid mounting operation is performed, the lid second portion 4b covers the upper portion of the handle portion 23. At this time, the lid-side convex portion 28 extends over the entire length of the handle portion 23 in the vertical direction. The container-side second transmission member 26b is pressed downward by coming into contact with the upper end portion of the container-side second transmission member 26b. Accordingly, the lid mounting operation is transmitted from the upper end portion of the handle portion 23 to the lower end portion via the inside of the handle portion 23 by the container-side second transmission member 26b. The container-side second transmission member 26b is moved from the upper position to the lower position against the urging force of the third urging member B3 by the pressing of the lid-side convex portion 28, and the container-side second transmission member 26b is moved downward. By moving to a position, the lower end part of the container side 2nd transmission member 26b is contacting the upper end part of the main body side 2nd transmission member 27b. Thereby, the main body side second transmission member 27b is pressed downward and moved to the second transmission position, and the container 3 is directly transmitted between the container side second transmission member 26b and the main body side second transmission member 27b. The lid mounting operation is transmitted from the side to the main body 1 side.

  In this way, the lid mounting operation is transmitted from the container 3 side to the main body 1 side by direct transmission between the container side second transmission member 26b and the main body side second transmission member 27b. Similarly to the transmission between the first transmission member 26a and the main body side first transmission member 27a, the direct transmission between the container side second transmission member 26b and the main body side second transmission member 27b is also performed on the container base 2. Outside, that is, in the outer space of the container table 2. Therefore, it is possible to appropriately transmit the lid mounting operation from the container 3 side to the main body 1 side, and the structure for transmitting the lid mounting operation from the container 3 side to the main body 1 side becomes simple.

As described above, the container mounting operation is transmitted between the container-side first transmission member 26a and the main body-side first transmission member 27a, and between the container-side second transmission member 26b and the main body-side second transmission member 27b. The lid mounting operation is transmitted in the mounting state in which the handle portion 23 is mounted on the main body second portion 9. When the handle portion 23 is mounted on the main body second portion 9, the main body second portion 9 is transmitted. The handle portion 23 can be guided to an appropriate position.
In other words, the upper end portion 9b of the main body second portion 9 is formed in a concave shape so that the lower end portion 23a of the handle portion 23 is fitted therein. However, as shown in FIGS. Of the four sides of the part 9b, three sides excluding the side close to the main body first part 8 are provided with the main body side wall part 29, and one side near the main body first part 8 is provided with the main body side wall part. 29 does not exist and is open in the horizontal direction. As a result, a body-side concave portion 30 that is U-shaped in plan view is formed in the upper end portion 9b of the second body portion 9 so that three directions are surrounded by the body side wall 29 and the remaining one direction is open. On the other hand, as shown in FIGS. 1 and 3, the lower end portion 23 a of the handle portion 23 is provided with a container side wall portion 31 extending downward, and the location of the container side wall portion 31 is rectangular in plan view. It is formed as follows. The container side wall portion 31 is configured to be freely fitted into the main body side recessed portion 30 in a state where the container side wall portion 31 is in contact with the inner side of the main body side wall portion 29, and even if the position of the handle portion 23 is shifted from an appropriate position, the main body side wall portion 29. The handle portion 23 can be mounted at an appropriate position of the main body second portion 9 by abutting and guiding the container side wall portion 31.

The container side first transmission member 26a and the container side second transmission member 26b are provided at the lower end portion 23a of the handle portion 23. However, the container side first transmission member 26a and the container side second transmission are provided. The member 26b is disposed close to the space surrounded by the container side wall 31. Further, the main body side first transmission member 27a and the main body side second transmission member 27b are provided on the upper end part 9b of the main body second part 9, but the main body side first transmission member 27a and the main body side second transmission member 27b are provided. 2 The transmission member 27 b is disposed in the vicinity of the main body side recess 30 surrounded by the main body side wall 29. Thereby, since each of the container side transmission member 26 and the main body side transmission member 27 is surrounded by the container side wall portion 31 and the main body side wall portion 29, the container side transmission member 26 and the main body side transmission member 27 are arranged. Can be prevented from being erroneously pressed and the like, and only by attaching the handle portion 23 to the second body portion 9, the space between the container-side first transmission member 26a and the body-side first transmission member 27a can be reduced. In this case, the container mounting operation can be transmitted in a simple manner and the lid mounting operation between the container side second transmission member 26b and the main body side second transmission member 27b can be transmitted easily and appropriately.
And since the lower end part of the handle part 23 is set above the lower end part of the container main body 22 with which the container base 2 was mounted | worn, even when the container main body 22 is placed on a desk etc., Since the container side transmission member 26 provided in the lower end part 23a does not hit the desk, the container side transmission member 26 is not easily damaged.

  In addition, since the main body side recess 30 is surrounded by the main body side wall 29 in the three directions and the remaining one direction is open, for example, even if a liquid such as water enters the main body recess 30, the liquid is released. Since it flows out of the main body side recessed part 30 from the made site | part, it can prevent that a liquid retains in the main body side recessed part 30. FIG. In this way, the guide / liquid retention is such that the handle portion 23 can be guided to a position where the container side transmission member 26 and the main body side transmission member 27 are in contact with each other, and liquid stay around the main body side transmission member 27 can be prevented. The prevention part is constituted by the main body side wall part 29 and the main body side concave part 30.

  As described above, the main body side transmission member 27 has the first and second non-transmission positions protruding upward from the bottom portion 9c of the concave upper end portion 9b of the main body second portion 9 by the biasing force of the biasing member (not shown). The position where the container side transmission member 26 and the main body side transmission member 27 are in contact with each other is above the bottom portion 9c of the concave upper end portion 9b in the main body second portion 9. On the other hand, the container base 2 attached to the main body 1 is maintained in the mounting state by the engagement between the container base side engaging portion 15 and the main body side engaging portion 16. The lower end portion of the main body second portion 9 is on the lower side than the bottom portion 9c of the concave upper end portion 9b. Thereby, the position where the container side transmission member 26 and the main body side transmission member 27 come into contact with each other is set above the lower end portion of the container base 2 attached to the main body 1. Therefore, for example, when the container base 2 and the container 3 have not been securely mounted, the liquid component out of the ingredients in the container 3 flows out between the container 3 and the container base 2, and the liquid component is the container base 2. Even if the liquid is accumulated in the gap between the lower end of the container and the main body 1, the liquid can be prevented from reaching the position where the container-side transmission member 26 and the main-body-side transmission member 27 are in contact with each other. The transmission with the side transmission member 27 is not adversely affected.

(Driving prohibition / driving permission means)
As described above, the drive prohibiting / driving permitting means is configured so that the motor 5 is only in the detection state where the first detection unit 24 detects the container mounting state and the second detection unit 25 detects the lid mounting state. Since driving is permitted and driving of the motor 5 is prohibited in other cases, this point will be described.

  As described above, the container mounting operation is transmitted from the container 3 side to the main body 1 side by direct transmission between the container-side first transmission member 26a and the main body-side first transmission member 27a. When transmitted to the side, the main body side first transmission member 27a moves to the first transmission position and is transmitted to the first detection unit 24 via the main body side first transmission member 27a. When the container mounting operation is transmitted by the main body side first transmission member 27a, the first detection unit 24 detects the container mounting state. The first detection unit 24 is configured to detect the main body side first transmission member 27a. Until the container mounting operation is transmitted by the motor 5, the motor 5 is controlled by restricting the ON operation (push-in operation) of the switch button 7 (actually, the first to third switch buttons 7 a to 7 c as will be described later). Is prohibited. Thus, the first detection unit 24 not only has a configuration as a detection unit that detects the container mounting state by transmitting the container mounting operation, but also detects the container mounting state by the first detection unit 24. A drive prohibition / drive permission means for prohibiting driving of the motor 5 in the absence of the motor 5 is also provided, and the detection unit is also used as the drive prohibition / drive permission means.

  As shown in FIG. 6 and FIG. 7, the first detection unit 24 includes a lock position (see FIG. 7A) that restricts the ON operation (pressing operation) of the switch button 7 and the ON operation (pressing operation) of the switch button 7. ) Is allowed to move to a lock release position (see FIG. 7B). The first detector 24 is provided in a form extending vertically through a through hole 35 formed in a plate-like support 34 that supports the switch button 7, and protrudes in the horizontal direction. A plurality of portions 24a are provided at intervals in the vertical direction. Then, as shown in FIG. 7A, when positioned at the lock position, the detection-side contact portion 24a contacts the button-side contact portion 7A of the switch button 7 to restrict the pushing movement of the switch button 7. The contact of the switch button 7 is restricted by this contact. On the other hand, as shown in FIG. 7B, when the first detection unit 24 is located at the unlock position, the detection-side contact portion 24a is located at a position different from the switch button 7 in the vertical direction. Even if the button 7 is pushed and moved, the detection-side contact portion 24a does not contact the button-side contact portion 7A, and the switch button 7 is allowed to be turned on. The first detector 24 is urged to return to the locked position by a biasing member (for example, an elastic spring) (not shown), and the container mounting operation is transmitted by the downward movement of the main body side first transmission member 27a. When this is done, it is provided so that it can move downward from the lock position to the unlock position along with its transmission, and mechanical detection that detects the container mounting state by moving downward from this lock position to the lock release position. It is configured as a part.

  Incidentally, in this embodiment, as the switch button 7, there are provided the first switch button 7a, the second switch button 7b, the third switch button 7c, and the fourth switch button 7d, but the first switch button 7a, Since the second switch button 7b and the third switch button 7c are switch buttons that are turned on when the motor 5 is driven, the first detection unit 24 does not perform the first operation until the container mounting operation is transmitted. The third switch buttons 7a to 7c are prohibited from being turned on, and the fourth switch button 7d that is turned on (push-in operation) when the drive of the motor 5 is stopped is shown in FIG. As shown in FIG. 7A, even if the detection side contact portion 24a that contacts the button side contact portion 7A is not provided and the container mounting operation is transmitted. ON operation has become a (pushing operation) possible.

  Further, as shown in FIGS. 6 and 7, the second and third switch buttons 7b and 7c are provided with a holding member 32 that holds the ON-operated state, and the ON operation is performed by the holding member 32. By maintaining this state, the driving of the motor 5 is continued. The holding member 32 is formed in a plate shape that penetrates the through hole 35 formed in the support 34 and extends in the vertical direction, and is arranged to be aligned with the first detection unit 24 in the horizontal direction. The holding member 32 is also provided so as to be movable in the vertical direction similarly to the first detection unit 24, and is biased downward by a biasing member (for example, an elastic spring) (not shown). It is provided so as to be movable in conjunction with the movement of the first detection unit 24 so as to move downward as it moves downward. When the second and third switch buttons 7b and 7c are turned on, the holding member 32 has a holding side that can be engaged with the button-side contact portion 7A provided in the second and third switch buttons 7b and 7c. An engaging portion 32a is provided, and the second and third switch buttons 7b and 7c are held in an ON-operated state by the engagement between the holding side engaging portion 32a and the button side contact portion 7A.

  The movement of the holding member 32 will be described. When the first detection unit 24 is moved downward from the locked position (see FIG. 7A) to the unlocked position (see FIG. 7B), the holding member 32 is shown in FIG. The holding-side engaging portion 32a is moved to a position where it can be engaged with the button-side contact portion 7A by the urging force of the outer urging member. When the second and third switch buttons 7b and 7c are turned on (pressed in), as shown in FIG. 7C, the button side contact portion 7A and the holding side engagement portion 32a are engaged. Thus, the second and third switch buttons 7b and 7c are held in an ON operation (push-in operation) state. Here, FIG. 7C shows a case where the third switch button 7c is held in an ON-operated state. When the fourth switch button 7d is turned on (push-in operation) while this holding is performed, the inclined portion 32b of the holding member 32 is pressed by the button side contact portion 7A of the fourth switch button 7d. The holding member 32 is moved upward, and the holding side engaging portion 32a is moved upward. As a result, the engagement between the button-side contact portion 7A and the holding-side engaging portion 32a is released, the holding in the state where the second switch buttons 7b and 7c are turned on is released, and the driving of the motor 5 is stopped. Is done.

  Returning to FIG. 5, the transmission of the lid mounting operation will be described. As described above, the lid mounting operation is performed by the direct transmission between the container side second transmission member 26b and the main body side second transmission member 27b. Although it is transmitted from the side to the main body 1 side, when transmitted to the main body 1 side, it is transmitted to the second detection unit 25 via the main body side second transmission member 27b. When the lid mounting operation is transmitted by the downward movement of the main body side second transmission member 27b, the second detection unit 25 is operated to turn on the switch and detect the lid mounting state. It consists of a detector.

Although not shown, the drive prohibition / drive permission means is provided in a control unit that controls the drive and drive stop of the motor 5, and whether or not the first to third switch buttons 7a to 7c are turned on. Such switch button ON / OFF information is configured to be freely input to the control unit. Therefore, as described above, when the first detection unit 24 detects the container mounting state, the first to third switch buttons 7a to 7c can be turned on. When it is determined that the first to third switch buttons 7a to 7c are turned on by the / OFF information, the first detection unit 24 recognizes that the container mounting state is detected.
In addition, the second detection unit 25 is configured to detect the lid mounting state by turning on the switch when the lid mounting operation is transmitted, and the switch ON / OFF information is also input to the control unit. It is configured freely. Therefore, when the drive prohibition / drive permission means determines that the switch is turned on based on the ON / OFF information of the switch, the drive prohibition / drive permission means recognizes that the lid mounting state is detected by the second detection unit 25. .
In this way, the drive prohibition / permission means detects the container mounting state at the first detection unit 24 based on the detection information of the first detection unit 24 and the second detection unit 25, and sends it to the second detection unit 25. Thus, the driving of the motor 5 is allowed only in the detection state in which the lid mounting state is detected, and the driving of the motor 5 is prohibited in other cases. Therefore, even when the container 3 is not mounted, as well as when the container 3 is mounted or the lid 4 is not mounted, the motor 5 is erroneously driven by prohibiting the driving of the motor 5. Can be prevented accurately.

  As described above, the first detection unit 24 and the second detection unit 25 detect the mounting state of the container mounting state and the lid mounting state as the main body side transmission members 27a and 27b move downward. When the amount of downward movement of the members 27a and 27b is equal to or greater than the set amount, detection of the mounting state of the container mounting state and the lid mounting state is started. That is, the first detection unit 24 and the second detection unit 25 detect the mounting state of the container mounting state and the lid mounting state when the downward movement amount of the main body side transmission members 27a and 27b is less than the set amount. Without starting, detection of the mounting state of the container mounting state or the lid mounting state is started only when the downward movement amount of the main body side transmission members 27a and 27b becomes equal to or larger than the set amount. Thereby, even if the user's finger or the like touches the main body side transmission member 27 by mistake, the main body side transmission members 27a and 27b move slightly downward, so that the first detection unit 24 and the second detection unit 25 are moved. However, it is possible to prevent erroneous detection of the mounting state of the container mounting state or the lid mounting state without detecting the mounting state of the container mounting state or the lid mounting state.

  In addition, in the electric cooking device according to the present invention, as shown in FIGS. 1 and 3, the main body side first transmission member 27a and the main body side second transmission member 27b are not pressed downward alone or simultaneously. A plurality of extending walls 33 extending upward from the bottom portion 9c of the concave upper end portion 9b in the second portion 9 are provided so as to surround the periphery of the main body side first transmission member 27a and the main body side second transmission member 27b. Yes. That is, as the extended wall 33, the first extended wall 33a surrounding the main body side first transmission member 27a and the main body side second transmission member 27b, the main body side first transmission member 27a, and the main body side second transmission member 27b. And a second extending wall 33b disposed between the two.

  As shown in FIG. 3, the first extending wall 33 a protrudes above the main body side first transmission member 27 a located at the first non-transmission position and is located at the main body side first position located at the second non-transmission position. It is comprised so that it may protrude above 2 transmission member 27b. In other words, the upper end of the first extending wall 33a is located above the upper end of the main body side first transmission member 27a located at the first non-transmission position, and the main body side is located at the second non-transmission position. It is located above the upper end of the second transmission member 27b.

  Further, the upper end of the second extending wall 33b in the up-down direction is the upper end of the main body side first transmission member 27a located at the first non-transmission position and the main body side first located at the second non-transmission position. 2 It is configured to be located at the same position as or at the upper side of at least one of the upper ends of the transmission member 27b. In this embodiment, the upper end portion of the main body side first transmission member 27a located at the first non-transmission position is lower in the vertical direction than the upper end portion of the main body side second transmission member 27b located at the second non-transmission position. Therefore, the upper end portion of the second extending wall 33b is equivalent to the upper end portion of the main body side first transmission member 27a located at the first non-transmission position in the vertical direction.

  The second extending wall 33b is configured as a protrusion that prevents both the detection of the container mounting state by the first detection unit 24 and the detection of the lid mounting state by the second detection unit 25 from being erroneously performed. ing. That is, the first detection unit 24 starts detection of the container mounting state when the main body side first transmission member 27a moves downward and the amount of movement exceeds the set amount. The position of the main body side first transmission member 27a when starting detection of the container mounting state is a position moved downward by a set amount from the main body side first transmission member 27a located at the first non-transmission position. The second detection unit 25 also starts detecting the lid mounting state when the main body side second transmission member 27b moves downward and the amount of movement exceeds the set amount. The position of the main body side second transmission member 27b when the detection of the lid mounting state is started is a position moved downward by a set amount from the main body side second transmission member 27b located at the second non-transmission position. Therefore, as described above, the upper end portion of the second extending wall 33b is positioned in the vertical direction on the main body side located at the upper end portion of the main body side first transmission member 27a located at the first non-transmission position and the second non-transmission position. The second transmission member 27b is positioned at a position equivalent to or at an upper side of at least one of the upper ends of the second transmission member 27b. Thereby, the position of the main body side first transmission member 27a when the detection of the container mounting state is started by the first detection unit 24, and the lid mounting state by the second detection unit 25, the second extending wall 33b. It can be configured to project upward from at least one of the positions of the main body side second transmission member 27b at the time of starting detection. Therefore, even if a user's finger or the like touches both the main body side first transmission member 27a and the main body side second transmission member 27b at the same time, the first detection unit 24 and the second detection unit are caused by the second extending wall 33b. 25, both the main body side first transmission member 27a and the main body side second transmission member 27b can be prevented from being pressed downward until the position where both of them start detection, and the first detection unit 24 detects the container mounting state. And it can prevent that both detection of the cover mounting state by the 2nd detection part 25 is performed accidentally.
