Description

[Detailed description of the invention] "Technical field of the invention" This invention relates to household appliances for cutting, slicing, mincing, squeezing and separating foods such as fruits and vegetables, and is particularly concerned with the processing of such foods. The present invention relates to a household electrical appliance that is equipped with a safety mechanism that prevents the processing tools used from being touched carelessly, in a corner, or unconsciously.

"Technical background of the invention and its problems" This type of household electrical appliance comprises a container, an open end located inside the container, and an inlet end for receiving food located outside the container. It is composed of a funnel-shaped passage member, a processing tool located within the container near the opening end of the passage member, and an electric motor for driving the processing tool.

One of the safety measures for this type of household electrical appliance is that the user must not inadvertently touch the processing tool while it is in operation, and the The reason lies in the ease with which food can be introduced.

Known household electrical appliances that meet these requirements have disadvantages in that they are complicated in structure, large in size, expensive, and difficult to handle. Due to this difficulty in handling, users often forget to use the safety mechanism even if the household appliance itself is equipped with a safety mechanism.
The work must be carried out under conditions that are unimaginable under normal circumstances.

"Purpose of the invention" The purpose of this invention is to provide a household electrical appliance that eliminates the drawbacks of the conventional appliance, has a simple structure, and is equipped with a safety mechanism that allows easy processing. There is a particular thing.

"Summary and Effects of the Invention" According to this invention, the above object is to provide a safety member that is movable between a first position that partially covers the inlet end of the passage member and a second position that completely opens the inlet end. This is achieved by providing a microswitch that forms part of the power supply circuit to the electric motor and is closed by a part of the safety member when the safety member is in the first position. be done.

According to a preferred embodiment of the invention, the safety member comprises a rod-like member, one end of which is rotatably attached to a pivot pin disposed on the lid, and the rod-like member is attached to the side of the passageway member. It consists of a parallel part extending parallel to the member, a closing part disposed in the same plane as the inlet end of the passage member, and a switch operating part for operating the microswitch.

``Effects of the invention'' The main advantages of this invention's household electrical appliances are:
If the safety member is in the first position, i.e. unless the inlet end of the passage member is partially blocked by the safety member, the electric motor, i.e. the processing tool, cannot rotate, thereby: It is possible to reliably prevent the user from touching the processing tool carelessly while the processing tool is being driven.

Further, when the safety member is in the first position, the inlet end of the passage member is only partially blocked by the safety member, as described above. , inserting an elongated food such as carrots or celery into the container through the open area of the inlet end that is not obstructed by the safety member;
This food can be processed.

Furthermore, since the safety member consists of a rod-shaped member whose one end is pivotally connected to the lid, the structure of the safety member is extremely simple and its operation is also very easy.

"Embodiment of the invention" An embodiment of the invention will be described below with reference to the drawings.

Referring to the drawings, the household electrical appliance 1 is equipped with processing tools suitable for processing work, so that
It can perform processing operations such as slicing, mincing, dicing, centrifuging, mixing, and pounding foods such as fruits and vegetables.

The household electric appliance 1 includes a body, and a chamber 3 in which an electric motor 4 is housed is formed within the body 2. A base plate 5 is arranged on the side of this chamber 3, and a container 6 is arranged on this base plate 5. This container 6 is removably fixed to the base plate 6 by conventional means (not shown). A drive shaft 6 extends inside the container 6, and the top of the container 6 is closed with a lid 7. The drive shaft 8 is
The drive shaft 8 is supported by the base plate 5, and the end portion of the drive shaft 8 within the base plate 5 is connected to the electric motor 4 via a transmission mechanism (not shown).

Food such as fruits and vegetables to be processed can be placed in the container 6 through a funnel-shaped channel member 9. Preferably, the passage member 9 is
It is formed integrally with the lid 7. When the lid 7 is positioned on the container 6, the passage member 9
It extends further upwards. The passage member 9 has an open end 10 located within the container 6 and an inlet end 11 located outside the container 6.

The drive shaft 8 is provided with a
A processing tool 12 that rotates together with this drive shaft 8 is detachably fixed. The processing tool 12 is
Extending in the radial direction of the drive shaft 8, the machining tool 12 rotates in close proximity to the open end 10 of the passage member 9.

The above-mentioned household electric appliance 1 includes a processing tool 1.
A safety mechanism is provided to prevent the user from accidentally touching the machining tool 12 through the passage member 9 while the machining tool 2 is being driven.

The safety mechanism mainly consists of a safety member 13 and a micro switch 14. This microswitch 14 constitutes a part of a power supply circuit (not shown) to the electric motor 4.

More specifically, in this embodiment, the safety member 13 is a U-shaped member,
This U-shaped member is made up of two rod-shaped arms 15, 16 that are different in length but extend parallel to each other, and a rod-shaped connecting portion 17 that connects one end of these arms 15, 16 to each other. Arm 15, 16
extend parallel to each other on both sides of the passage member 9 when the connecting portion 17 is located in the same plane as the inlet end 11 of the passage member 9. The other end of the arm 15 is
It is rotatably attached to a pivot pin 18 disposed on the lid 7. The pivot pin 18 is located laterally to the passage member 9 and extends parallel thereto. On the other hand, the other end 1 of the arm 16
6a extends into the chamber 3 through a slot 19 formed in the body 2. This slot 19 is
It is formed into an arc shape centered on the axis of the pivot pin 18. The lower end 16a of the arm 16 is connected to the connecting portion 17 of the safety member 13 at the inlet end 1 of the passage member 9.
1 is adapted to close the microswitch when in a first position extending across the center of the microswitch.

In the first position, the connecting portion 17 of the safety member 13
This can reliably prevent the user from accidentally inserting his or her hand into the passage member 9 and touching the processing tool 12 while the processing tool 12 is rotating. Also,
The connecting portion 17 moves from the first position to the passage member 9.
can be positioned in a second position in which the inlet end 11 of is fully open. When in the second position, the other end 1 of the arm 16 in the safety member 13
6a is separated from the micro switch 14, and by opening the micro switch 14, the driving of the electric motor 4, that is, the rotation of the processing tool 12 can be stopped. As described above, according to this invention, the machining tool 12 cannot be rotated unless the safety member 13 is positioned at the first position, the so-called safe position.

This invention is not limited to the above-mentioned embodiment, and may further include means such that the electric motor 4 is not driven unless the lid 17 is in an appropriate closing position with respect to the container 6. good. In this case, a microswitch is further arranged in the chamber 3, while the lid 17 has a microswitch which extends into the chamber 3 through the slot 19 and operates the microswitch when the lid 17 is in the appropriate closed position. Teeth may also be provided for closure.

It goes without saying that the dimensions of the U-shaped safety member 13, that is, the lengths of the arms 15 and 16, can be varied depending on the height dimension of the passage member 9 with respect to the lid 7. Connecting part 17
The length and width dimensions of the passage member 9 can also be varied depending on the opening area of the inlet end 11 of the passage member 9.
