Abstract

PROBLEM TO BE SOLVED: To provide an electric cooker capable of reliably obtaining predetermined performance by improving in reliability of fixing of a rotational direction of a mesh filter with a frame and preventing the mesh filter with a frame from being normally operated when it is vertically inverted, and convenient in use as well.SOLUTION: When a mesh filter 35 with a frame is vertically inverted, a flange 38 of a filter 29 is pushed up by a lower surface of a lower frame of the mesh filter 35 with a frame 44 by allowing a protrusion 49 to initially collide with a separation basket 28, a lid 31 is also floated by the floating of the filter 29, and thus a hole part 47 of the lid 31 and a claw part 46 are not allowed to fit to each other. At the same time, a protrusion part 39 and the protrusion 49 are engaged in a state that the mesh filter with a frame is normally vertically set, so that the rotation of the mesh filter 35 with a frame is stopped at an engaged position at rotation and can be fixed at a constant position, and thus maintaining a stable operating state.

Description

  The present invention relates to an electric cooker such as a juicer for producing juice by mainly pulverizing vegetables, fruits and the like to separate a liquid and a solid.

  Conventionally, this type of electric cooking device has a mesh filter 2 with a frame in a cylindrical filter 1 as shown in FIG. 9, and the mesh filter 2 with a frame and the filter 1 are fixed by press fitting. When the frame-equipped mesh filter 2 is attached to the filter 1, the user determines the vertical direction by display. The mesh filter 2 with a frame is an attachment used when it is desired to make a clear juice (a high degree of separation between a liquid and a solid). (For example, see Patent Document 1)

Japanese Patent Publication No. 61-39806

  However, in the conventional configuration, there is a risk that the framed mesh filter may be turned upside down, and when it is turned upside down, performance does not appear. (For example, the upper flange of the mesh filter with a frame has the purpose of collecting debris. However, if it is turned upside down, the debris (solid matter) cannot be accumulated, and the debris leaks into juice (liquid). A large amount of debris is mixed and the juice performance does not come out.) The rotation of the mesh filter with a frame is fixed by press-fitting, but the rotation direction is unstable when there is dimensional variation or deformation. Therefore, if the mesh filter with a frame rotates during operation, vibration or the like may be adversely affected.

  The present invention solves the above problems, improves the reliability of fixing the rotation direction of the mesh filter with frame, and prevents normal operation when the mesh filter with frame is turned upside down, An object of the present invention is to provide an electric cooker that can reliably obtain a predetermined performance and is easy to use.

  In order to solve the above-mentioned conventional problems, a protrusion is provided inside the upper flange of the filter, engages with the protrusion when rotated, and the filter is installed when the framed mesh filter is turned upside down. A protrusion to be lifted is provided on the upper side of the upper flange of the mesh filter with frame.

  As a result, when the framed mesh filter is turned upside down, the filter can be lifted, so the lid cannot be set and cannot operate normally, so the user can be aware of the abnormality so that it can be set correctly. . At the same time, the protrusion and the protrusion engage with each other when the upper and lower sides are set normally, so that the mesh filter with a frame at the time of rotation stops at the engagement position and can be fixed at a fixed position. Can be maintained.

  The electric cooking device of the present invention can surely obtain a predetermined performance and can improve usability.

You can notice the abnormality. At the same time, the protrusion and the protrusion engage with each other when the upper and lower sides are set normally, so that the mesh filter with a frame at the time of rotation stops at the engagement position and can be fixed at a fixed position. Can be maintained.

  In addition to the first invention, the second invention is provided with a power supply interlock on the main body and a container detector that releases the interlock when the main body is moved down to a predetermined position. A safety pin capable of depressing the container detection body is formed on the container, and the safety pin depresses the container detection body so that the container detection body can release the interlock and turn on the power. As a result, if the upper and lower sides of the mesh filter with the frame are not set correctly, the power cannot be turned on, so that the user can be surely recognized and safer.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that this embodiment does not limit the present invention.

(Embodiment 1)
1 and 7 show a cross-sectional view of the electric cooking device according to the first embodiment of the present invention. FIG. 2 is an enlarged cross-sectional view of a main part of the electric cooker, and FIGS. 3 to 6 are perspective views of the main part.

  1 to 7, the electric cooker according to the first embodiment includes a main body 24 provided with drive-side connectors 22 and 23 on the output side of the motor 21, and a follower that is detachably engaged with the drive-side connectors 22 and 23. A cutter 27 having side connectors 25 and 26 and a separation rod 28 are provided. A removable filter 29 for separating the liquid is provided in the separation rod 28, and a container 30 for receiving the liquid separated by the filter 29, and the container 30 It is set as the structure which has the lid | cover 31 which covers.

  The filter 29 has a comb portion 32, and juice is separated at this portion. Further, the convex portion 34 is engaged with the concave portion 33 of the separating rod 28, and the separating rod 28 is rotated in a direction in which the engaged convex portion 34 is not detached.

  35 is a mesh filter with a frame, and the outer periphery of the mesh filter 36 wound in an annular shape is covered with a resin frame 37 such as PP and is integrated into a cylindrical shape by insert molding, and is detachably engaged with the inside of the filter 29. Yes. Specifically, there are four protrusions 39 provided inside the flange 38 formed on the upper portion of the filter 29 and an annular rib 41 provided on the upper side of the second flange 40 formed on the upper portion of the mesh filter 35 with frame. By engaging, the upward movement of the mesh filter with frame 35 is regulated. The mesh size of the mesh filter 36 is set to several tens of meshes or hundreds of meshes.

  Since the framed mesh filter 35 and the filter 29 float upward during the rotating operation, a gap 42 is usually generated between the lower part of the framed mesh filter 35 and the separating rod 28 during the rotating operation. The dimensions are set so that the air gap 42 is formed during the rotation operation even in the worst condition including the component variation in the height direction of the filter 29 and the mesh filter 35 with the frame. Further, a protrusion 43 having a height corresponding to the dimensioned gap 42 is provided on the lower frame 44 of the framed mesh filter 35, so that the gap 42 is reliably formed.

  For example, when the juice is made with kiwi, which is most likely to cause abnormal vibrations, if an experiment is performed with a gap of 0 mm during rotation, abnormal vibrations occur once every several times, and under the condition of a gap of 0.1 mm. Since no abnormal vibration occurred when the experiment was performed, a gap of at least 0.1 mm or more is necessary. If the gap is increased, the safety is further improved, but the amount of residue leaked from the gap is increased, and the clear juice performance is lowered. Therefore, an appropriate setting is required.

  When the juice is being squeezed with the frame-equipped mesh filter 35 attached, if the gap between the lower frame 44 and the separation basket 28 is small, the mesh filter 36 is accumulated in the mesh filter 35 with the frame when covered with the squeezed residue. It has been found that there is no place for moisture to escape and abnormal vibration may occur due to the effect of unbalanced accumulated water. However, since the air gap 42 is provided, a gap for moisture to escape is secured and abnormal vibration is prevented. Can be done. In addition, since the frame-equipped mesh filter 35 is disposed inside the filter 29, it is convenient for storage, and the talent is reduced.

  The main body 24 has a built-in clamp mechanism 45 that clamps the lid 31, and a claw 46 of the clamp mechanism 45 and a hole 47 formed in the lid 31 are engaged with each other. A spring 48 is attached to the clamp mechanism 45, and the claw 46 is biased to the outside of the main body 24.

  Four protrusions 49 are provided on the upper part of the annular rib 41 provided on the upper side of the second flange 40 formed on the upper part of the mesh filter 35 with a frame, and the protrusions 49 engage with the protrusions 39 when rotated. When the upper and lower sides of the filter 29 are turned upside down, the flanges 38 of the filter 29 are pushed up by the lower surface of the lower frame 44 of the framed mesh filter 35 to lift the filter 29 so that the lid 31 is also lifted. The height is set so that 46 cannot be engaged.

  The main body 24 incorporates a power supply interlock (not shown) and is interlocked with a container detection body 50 that releases the interlock when it is moved down to a predetermined position. Further, a safety pin 51 that can push down the container detection body 50 when the lid 31 is properly engaged with the claw 46 is formed on the container 30, and the safety pin 51 pushes down the container detection body 50, thereby the container detection body 50. Is configured so that the interlock can be released and the power can be turned on.

  About the electric cooker comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  The cutter 27 is rotated via the drive-side connector 22 to which the power of the motor 21 is transmitted and the driven-side connector 25 to cut the cooked food, and the spinner is also rotated via the drive-side connector 23 and the driven-side connector 26. The filter 29 separates the liquid and the solid matter. The liquid separated by the filter 29 passes through the container 30 and is discharged to the outside. When making clear juice, a removable mesh filter 35 with a frame may be attached to the inside of the filter 29.

  Here, when the framed mesh filter 35 is turned upside down as shown in FIG. 8, the protrusions 49 come into contact with the separation rod 28, so that the flange 38 of the filter 29 is attached to the lower frame of the framed mesh filter 35. The filter 29 is lifted by pushing up on the lower surface of 44. If it does so, the lid | cover 31 will also float and the hole 47 and the nail | claw 46 of the lid | cover 31 cannot be engaged. Therefore, since the lid 31 cannot be set and cannot operate normally, the user can be made aware of the abnormality so as to set it correctly. At the same time, since the protrusion 39 and the protrusion 49 are engaged with each other when the upper and lower sides are normally set, the mesh filter 35 with the frame at the time of rotation stops rotating at the engagement position and can be fixed at a fixed position. Can be maintained.

  Moreover, since the safety pin 51 which can push down the container detection body 50 when the lid | cover 31 correctly engage | combines with the nail | claw 46 is formed in the container, if the upper and lower sides of the mesh filter 35 with a frame are not set correctly, power is turned on. This also makes it possible for the user to be surely recognized and safer.

  As described above, in the present embodiment, the reliability of fixing the rotation direction of the framed mesh filter 35 is improved, and the framed mesh filter 35 cannot be operated normally when the framed mesh filter 35 is turned upside down. Thus, the predetermined performance can be surely obtained and the usability can be improved.

  As described above, the electric cooking device according to the present invention improves the reliability of fixing the rotation direction of the mesh filter with a frame and prevents the frame mesh filter from operating normally when the frame mesh filter is turned upside down. In addition to being able to reliably obtain the specified performance, it is also easy to use, so it can be used for other applications to obtain clear juices and clear liquids using a mesh filter with a frame and a separation basket. Is also applicable.
