Description

  The present invention relates to a food preparation device for preparing foods such as fruits and vegetables.

  Conventionally, in a food preparation device (for example, a juicer) that prepares foods such as fruits and vegetables, a preparation device main body (for example, a juicer main body) provided with a drive means and the like is detachably engaged with the preparation device main body. A mounting body (such as a main body cover) and a fixture provided between the preparation device main body and the mounting body, and by pressing the fixing tool, It was set as the structure which can cancel | release engagement and can remove a mounting body. The fixture is configured to be freely changeable between a first posture and a second posture, and is configured to be biased to the first posture, and is placed in an engaged state that takes the first posture. Is engaged and fixed to the preparation device main body, and the engagement and fixation is released in the disengaged state in which the second posture is taken by the pushing operation, and the mounting body can be detached from the preparation device main body.

  In the following description, in order to facilitate understanding, an example of a juicer in which the main body cover serves as a mounting body in the present application will be described.

  In the above structure, simply by changing the posture from the first posture to the second posture by pushing the fixing tool and releasing the engagement between the preparation device main body and the main body cover, the pushing operation on the fixing tool is completed. Then, since the fixture is biased to the first posture, it returns to the engaged state in the first posture again, and unless the fixture is always pushed, the engaged state cannot be maintained, For example, it is necessary to perform an operation of removing the main body cover with one hand while pressing the fixing tool with one hand, which is not convenient. In particular, in the case where a pair of fixing tools are provided, it is necessary to perform an operation of detaching the main body cover with both hands while pressing the fixing tools with both hands, which further reduces usability.

Therefore, in order to solve the above problem, for example, in a juicer having a juicer body, a body cover, and a fixture provided between the juicer body and the body cover, the fixture is changed from the first posture to the second posture. An invention has been proposed in which a body cover is lifted by an inclined portion of a slider separately provided on a juicer body as the posture is changed (see Patent Document 1).
According to the invention, after the fixing tool is pushed in and the fixing tool is changed from the first posture to the second posture and the pushing operation of the fixing tool is finished, the body cover is lifted by the inclined portion of the slider. Even if it returns to a 1st attitude | position, it can prevent that a juicer main body and a main body cover will be in an engagement state again. As a result, even after the user has performed the pushing operation of the fixing tool for releasing the engagement, the user can lift it with sufficient time without worrying about the inconvenience of re-engaging the juicer body and the body cover. The main body cover can be removed.For example, after pressing the pair of fixing tools with both hands, the main body cover can be slowly removed with one hand, which is very convenient to use. It has become.

  According to the first characteristic configuration described above, in the food preparation device, the fixture is pushed inward (the inside of the food preparation device, the same applies hereinafter) to change the posture, thereby engaging the preparation device main body and the mounting body. The state can be changed between the state and the disengaged state. And with a state change to a disengagement state, a mounting body is lifted from a preparation device main body by the lifting operation part provided in the fixing tool, and a mounting body can be removed easily. That is, when the fixture is pushed inward, and the posture of the fixture is changed from the first posture to the second posture, the state of the preparation device main body and the mounting body is changed from the engaged state to the disengaged state. The engagement is released. As the state is changed to the disengaged state, the mounting body comes into contact with the lifting operation portion provided on the fixture, and is lifted along the lifting operation portion, and comes to the lifting position. Thereby, the user can easily perform the operation of removing the placed body in the lifted state when the fixing tool is pushed inward to release the engaged state. Furthermore, since the lifting operation unit is provided integrally with the fixture, it is not necessary to provide the lifting operation unit with a separate member in the preparation device body, and the number of parts and the assembly process are increased during manufacturing. Therefore, it can be efficiently manufactured.

  In addition to the first characteristic configuration, the second characteristic configuration of the food preparation device according to the present invention is a lifting position in which the mounting body is lifted from the preparation body by the action of the lifting operation unit. The holding tool for holding the body in position is provided in the fixture.

In other words, even if the inward pushing operation to the fixing tool is completed and the fixing tool returns or returns to the first position by urging to the first position, the mounting body is provided at the lifting position at the lifting position. Since the position is held by being locked to the holding portion and deviated from the position where it is engaged, it is possible to prevent the mounting body and the preparation body from being engaged again and to release the engagement. In the state, the lifted state can be stably maintained, and the mounting body can be easily removed. Thus, the user can perform the operation of removing the mounting body with a sufficient time, and is worried that the mounting body becomes unstable and the mounting body shifts and comes off. There is no need. Furthermore, since the holding part is provided integrally with the fixture, it is not necessary to provide the holding part with a separate member in the preparation device body, and the number of parts and the assembly process are increased during manufacturing. Therefore, it can be manufactured efficiently.

  In order to achieve the above object, a food preparation device according to the present invention comprises a preparation body provided with a driving means, and a mounting body used on the preparation body. Is configured to form at least a part of the food preparation means, and the posture can be freely changed between the first posture and the second posture between the preparation body and the mounting body, and biased to the first posture. The fixture is engaged with and fixed to the preparation device main body in an engaged state in which the fixture takes the first posture, and the fixture takes the second posture by a pushing operation. The food preparation device in which the placing body can be detached from the preparation device main body in a combined release state, and the third characteristic configuration thereof is a lifting position in which the placing body is lifted from the preparation device body, In the point which provided the holding | maintenance part which carries out position holding | maintenance of the said mounting body in the said fixture.

  According to the third feature configuration, in the food preparation device, the fixture is pushed inward to change the posture, so that the preparation device main body and the mounting body are engaged and disengaged. State changes can be made. And with the state change to the disengaged state, the mounting body is held in the lifted position where the mounting body is lifted from the preparing body, and the preparation body and the mounting body are disengaged. In the state, the lifted state can be stably maintained, and the mounting body can be easily removed. That is, when the fixture is pushed inward and the posture of the fixture is changed from the first posture to the second posture, the preparation device main body and the mounting body are changed from the engaged state to the disengaged state. The engagement is released. In the disengaged state, at the lifted position where the mounting body is lifted, it is locked and held at the holding portion provided on the fixture. Even if the fixture is returned to or returned to the first posture by urging to the first posture, the mounting body is held in position by being locked to the holding portion of the fixture. The state in which the mounting body is lifted in the disengaged state can be stably maintained, and the mounting body can be easily removed. Thereby, even after the user performs an inward pushing operation to the fixture for releasing the engaged state, the user is concerned about the inconvenience that the preparation device main body and the mounting body are again engaged. The operation of removing the mounting body that has been lifted and held in a stable state without any time can be performed. Furthermore, since the holding unit is provided integrally with the fixture, it is not necessary to provide a holding unit with a separate member in the preparation device body, and the number of parts and the assembly process are increased during manufacturing. Therefore, it can be manufactured efficiently.

The posture is freely changeable and is biased to the first posture by a spring 15. Here, the first posture is a posture in which the fixing tool 14 is pushed outward by the biasing force of the spring 15, and the second posture is that the fixing tool 14 is pushed inward against the biasing force of the spring 15. It is posture. When the fixture 14 is in the first posture, the main body cover 70 and the main body 10 are engaged with each other. However, even in the first posture, the main body cover 70 is in the lifted position. When the operation is performed, the main body cover 70 and the main body 10 are displaced in the vertical direction, so that the disengaged state is maintained without being engaged. When the fixture 14 is in the second posture, the main body cover 70 and the main body are in the disengaged state in which the engagement is released.

The fixture 14 includes the engaging portion 2, the lifting operation portion 3, the holding portion 4, and the pressing portion 14a as a unit. As shown in FIG. 7, the fixture 14 is configured to include a member whose upper part is divided into an inner part and an outer part when viewed in a cross section. As the engaging portion 2, the flat portion 2 a is provided on the lower surface of the upper end outer side of the inner member so as to engage with the flat portion 76 a of the receiving portion 75 in the main body cover 70. As the lifting operation unit 3, the fixing tool 14 is tilted so that the main body cover 70 can be lifted by coming into contact with the contact portion 78 a of the receiving portion 75 in the main body cover 70 as the posture is changed from the first posture to the second posture.

The main body cover 70 is provided with a flat surface portion 76 a that engages with the flat surface portion 2 a of the fixture 14 on the inner upper surface of the receiving portion 75 in the main body cover 70.

  Therefore, when the main body 10 and the main body cover 70 are brought into the disengaged state in which the engagement is released, the pressing portion 14a of the fixing tool 14 is pushed inward from the state of FIG. The fixture 14 can be changed in posture from the first posture to the second posture, and the flat surface portion 76a of the main body cover 70 and the flat surface portion 2a of the fixing device 14 can be disengaged. Accordingly, due to the posture change from the first posture to the second posture, the abutting portion 78a of the main body cover 70 abuts on the inclined portion 3a provided on the fixture 14, and the main body cover 70 is moved to the inclined portion 3a. (See FIG. 7B), the main body cover 70 is lifted to the lifted position. When the pushing operation of the fixing tool 14 toward the inside is completed, the main body cover remains in the disengaged state when the fixing tool 14 changes its posture between the first posture and the second posture by the urging force of the spring 15. At the position where 70 is lifted, the notch 77a provided in the receiving portion 75 of the main body cover 70 is held and fixed to the convex portion 4a of the fixture 14 (see FIG. 7C). At this time, since the engagement is released while the main body cover 70 is lifted, the main body cover 70 can be easily detached from the main body 10.

  On the other hand, when the main body 10 and the main body cover 70 are brought into an engaged state, the main body cover 70 is placed on the slope 5a at the time of re-engagement provided on the upper surface of the upper end of the inner member of the fixture 14. In the state (see FIG. 7 (a) one-dot chain line), by pushing the entire body cover 70 downward, the contact portion 81a provided at the lower inner tip of the body cover 70 descends along the slope 5a, The fixing tool 14 is pushed inward, and the flat surface portion 76a of the main body cover 70 and the flat surface portion 2a of the fixing device 14 are engaged (see a solid line in FIG. 7A). When the main body cover 70 is held by the convex portion 4a, the held main body cover 70 is once lifted and placed again on the inclined surface 5a, and then the entire main body cover 70 is removed in the same manner as described above. By pushing downward, the planar portion 76a of the main body cover 70 and the planar portion 2a of the fixture 14 can be brought into an engaged state.

  With these configurations, the user does not have to worry about the inconvenience that the main body 10 and the main body cover 70 are engaged again even after the pushing operation of the fixing tool 14 is performed to release the engaged state. Then, it is possible to perform an operation of removing the main body cover 70 in a state where the body cover 70 is lifted with sufficient time and held in position. Further, since the lifting operation unit 3 and the holding unit 4 are provided integrally with the fixture 14, it is not necessary to provide the lifting operation unit and the holding unit in a configuration in which the main body 10 is a separate member.
