Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to an electric cooking machine that is mainly used in general households to mince carrots, onions, etc., and to quickly make mayonnaise and dressing. .

Conventional structure and its problems Conventionally, when making mayonnaise with this type of electric cooking machine, the container 1 is attached to the main body case containing a built-in electric motor as shown in Fig. 1, and the power of the electric motor is inside the container 1. Set up the cutter mount 3 with two knife cutters 2 attached to the top and bottom of the transmission, and cut the raw egg,
After putting cooking ingredients such as vinegar and seasonings other than salad oil into the container 1, turn on the switch leading to the electric motor and measure the ingredients into the recess 5 provided in the container lid 4 while stirring the ingredients in the container 1 with two knife cutters. Pour pre-measured salad oil into the recess 5 using a cup, etc.
It was common to make mayonnaise by stirring and mixing raw eggs, vinegar, etc. and salad oil by gradually dropping small amounts into the container 1 through a hole 6 provided at the bottom of the recess 5.

In a conventional electric cooking machine configured in this way,
Since the hole 6 provided at the bottom of the concave part 5 of the container lid 4 is always open, it is impossible to measure the salad oil in the concave part 5, and there are problems such as the need for a separate measuring cup and the problem of cooking conditions. If the operation is stopped midway to confirm that the oil is being removed, the salad oil poured into the recess 5 will drip into the container 1, making it difficult to confirm until the entire amount of salad oil in the recess 5 has dripped. In addition, if you want to stop the dripping of the salad oil poured into the recess 5 midway depending on the quality of the mayonnaise, it is necessary to remove the container lid 4 in a hurry. I had a problem with it falling. Further, there was a problem that the material in the container 1 would scatter from the hole 6 while stirring the material with the knife cutter 2.

Purpose of the Invention The present invention takes these conventional problems into consideration, and provides an electric cooking machine that prevents ingredients from dripping or scattering from the hole provided in the container lid, and improves the quality of cooking. The purpose is to

Structure of the Invention In order to achieve the above-mentioned object, the present invention forms a recess in the top surface of the container lid that covers the container opening, provides a hole at the bottom of the recess, and inserts a valve shaft into the hole to open and close the hole. The structure includes a valve and an inner valve.

When this container lid is attached to a container placed on the main body, the container lid is attached so as to be slightly raised from the container. Then, when an external force is applied and the container lid is pushed down slightly, a part of the container lid turns on the switch leading to the electric motor, and the electric motor and knife cutter rotate, and the lower end of the valve shaft is pushed up by the top surface of the cutter mount, causing the outer valve to open. is starting to open. When the container lid is pushed down further, the inner valve closes the hole.

DESCRIPTION OF EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. In FIGS. 2 to 7, 11 is a main body case, and inside the main body case, an electric motor 12 is attached to a chassis 13 with screws 14. The chassis 13 is attached to the main body case 11 with a cushion rubber 15 and screws 16. A pinion 18 is attached to the shaft 17 of the electric motor 12. An output gear 19 is driven by the pinion 18, and the output gear 19 is attached to the main shaft 20. The main shaft 20 is attached to the chassis 13 via an oilless bearing 21. A connector 22 is attached to the tip of the main shaft 20, and a cutter mount 23 is attached to the connector 22.
is detachable, and the upper part of the connector 22 fits into the groove provided in the cutter mounting base 23, and the electric motor 12
power is now being transmitted. Two knife cutters 24 are attached to the cutter mount 23 at the top and bottom. The main case 11 has a container 2
5 is placed thereon and is removable. The opening of this container 25 is covered with a removable container lid 26. A recess 27 is formed in the container lid 26, and a hole 28 is provided at the lowest part of the recess 27. 29 is the valve stem and hole 28
An outer valve 30 and an inner valve 31 are attached to open and close the valve. A protrusion 32 is provided on the outside of the container lid 26. The upper surface of the main body case 11 is covered with an upper main body 33, and the upper main body 33 has a thin slit-shaped groove 34 formed therein into which a protrusion 32 provided with a container lid 26 is fitted so as to be able to freely swing up and down. A small hole 36 is provided in the bottom surface 35 of the groove portion 34, and this small hole 36
A sliding plate 38 is installed with a rubber gasket 37 as a seal.
is inserted. The sliding plate 38 is a coil spring 39
is supported by The electric motor 12 is operated by a microswitch 40 whose contacts are operated by a sliding plate 38. Further, the lower part of the main body case 11 is covered with a back plate 41, and legs 42 are attached to the back plate 41.

Next, the operation and operation of the electric cooking machine will be explained. Attach the container 25 to the main body case 11,
Cutter mounting base 2 with knife cutter 24 attached
3 while fitting it into the connector 22. Next, when making mayonnaise, raw eggs, vinegar, seasonings, and other ingredients other than salad oil are put into the container 25, the opening of the container 25 is covered with the container lid 26, and the protrusion 32 is placed on the top of the main case 11. It is set so as to fit into a thin slit-shaped groove 34 provided in the upper main body 33 covering the main body 33. At this time, the sliding plate 38 is biased by the coil spring 39 and pushes up the protrusion 32, so between the container 25 and the container lid 26 and between the lower end of the valve shaft 29 and the upper surface of the cutter mount 23. There are some gaps. In this state, when salad oil is poured into the recess 27 of the container lid 26, the salad oil will accumulate in the recess 27 because the hole 28 provided in the recess 27 is closed by the valve 29. From this state, when the container lid 26 is pushed downward by external force by hand, the protrusion 32 moves the sliding plate 38 downward. This sliding plate 38 also controls the micro switch 40.
The electric motor 12 is rotated by operating in the ON state. The rotation of the electric motor 12 is transmitted to the knife cutter 24 to stir the material in the container 25. on the other hand,
When the container lid 26 is pushed down lightly, the lower end of the valve shaft 29 is pushed up by the upper surface of the cutter mount 23, opening the outer valve 30, and the salad oil injected into the recess flows into the hole 28.
It is dropped into the container 25 and mixed with the ingredients in the container 25 by the rotating knife cutter 24 to make mayonnaise. Here, the salad oil dripping from the concave portion 27 of the container lid 26 is immediately removed from the inner valve 31.
It drips onto the surface and is blown to the outside where the circumferential speed is faster.
For this reason, the material in the container 25 is better agitated. Furthermore, although the material inside the container is scattered by the stirring of the knife cutter 24, the material hits the inner valve 31 and therefore does not scatter to the outside through the hole 28.

Next, when the container lid 26 is pushed further downward, the valve stem 29 is pushed up, and the inner valve 31 closes the hole 28 and stops dripping of the salad oil. Therefore, the ingredients in the container 25 can be stirred while checking the quality of the mayonnaise in the container 25 and adjusting the dripping amount of salad oil.

When you finish making mayonnaise and remove your hand pushing down the container lid 26, the sliding plate 38 is pushed up by the coil spring 39 and the micro switch 40 is pushed up.
is turned OFF, and the sliding plate 38 closes the protrusion 32.
In order to push up the container lid 26 through the valve stem 29
The lower end of the cutter is separated from the upper surface of the cutter mount 23, and the outer valve 30 closes the hole 28, stopping the dripping of salad oil.
Therefore, even if salad oil remains in the recess 27 of the container lid 26, it will not drip.

Effects of the Invention As is clear from the above description of the embodiments, the present invention provides a hole in the recess of the container lid with an outer valve and an inner valve for opening and closing the hole, thereby making it possible to stir the ingredients and salad oil in the container. Not only does it get better, but you can also stir the ingredients in the container while checking the doneness of the mayonnaise in the container and adjusting the dripping amount of salad oil.
In addition, it is possible to prevent ingredients from scattering outside during operation, and to prevent salad oil from dripping from the holes when the operation is stopped or when the container lid is removed and moved. Furthermore, it has great practical effects, such as being able to measure the amount of salad oil in the recessed part of the container lid.
