An example of the embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing a schematic configuration example of the cooking utensil 1 according to the first embodiment, and shows a side view in which the cooking utensil 1 is partially broken. FIG. 2 is a diagram showing a schematic configuration example of a check valve of the cooking utensil 1 according to the first embodiment, and shows a side sectional view of the check valve. In the present embodiment, a mixer will be described as an example of a cooking utensil that crushes and stirs and processes foodstuffs by a rotating cutter (hereinafter, referred to as “crushing and the like”).

The cooking utensil 1 includes a main body 10, a pedestal 20, a container 30, a cutter 40, and a stopper 50. In the cooking utensil 1, the pedestal 20 and the container 30 are connected and connected to the main body 10, the stopper portion 50 is used to cover the cooking utensil 1, and the cutter 40 is used to crush the foodstuff. The pedestal 20 is integrally or detachably connected to the main body 10, and the container 30 is integrally or detachably connected to the pedestal 20.

The main body 10 is provided with an operation unit including a switch button 11 or the like instructing a process such as crushing, an electric motor (not shown) for driving a cutter 40 described later, and the like. A connecting mechanism (not shown) is connected to the electric motor, and when the pedestal 20 is attached to the main body 10, the connecting mechanism 23 of the pedestal 20 and the connecting mechanism of the main body 10 are connected, and the electric motor of the main body 10 generates the connection mechanism. The power is transmitted to the shaft body 22 of the pedestal 20, which will be described later, and further to the cutter 40.

The pedestal 20 includes a recessed portion 21, a shaft body 22, and a connecting mechanism 23. The pedestal 20 is detachably mounted on the main body 10. The recessed portion 21 is formed on the upper portion of the pedestal 20, and the bottom surface of the recessed portion 21 functions as the bottom surface of the container 30. A screw groove and a rubber seal (not shown) are formed on the inner wall of the pedestal 20 forming the recessed portion 21. The shaft body 22 is rotatably supported inside the pedestal 20. The connecting mechanism 23 is connected to the lower end of the shaft body 22.

The container 30 includes a handle 31 and a screw thread 32. The container 30 is formed in a substantially cylindrical shape, and a handle 31 is provided on the outside thereof. A screw thread 32 is provided on the lower outer surface of the container 30. The screw thread 32 fits into the thread groove of the pedestal 20, whereby the container 30 and the pedestal 20 are connected, the lower end of the screw thread 32 is pressed against the rubber seal, and the connecting portion is sealed by the rubber seal.

The container 30 is formed so that the food material is put into the container and the crushed food material, the processed liquid material, and the like are stored. The cross-sectional shape inside the container 30 is formed so as to have a substantially constant width in the vertical movable range of the plug portion 50, which will be described later. Since the cutter 40 described later is arranged in the lower part of the container 30, the lower limit line of the movable range may be defined above the cutter 40 so that the stopper 50 does not interfere with the cutter 40. For example, the lower limit line can be defined by making the cross-sectional shape inside the container 30 narrower than the outer diameter of the stopper 50, or by providing a wall protruding toward the inside of the container 30. In order to prevent a decrease in the crushing ability due to the food being pushed by the blade of the cutter 40 and moving together, a portion that functions as a resistor may be provided below the lower limit line, such as providing unevenness on the inner wall of the container 30. A part of the upper end of the container 30 projects laterally so that the liquid material in the container 30 can be discharged to the outside. The raw material of the container 30 is not limited, and is formed by using, for example, glass, a transparent resin, or the like.

Of course, the shape of the container 30 is not limited to a cylinder. That is, the cross-sectional shape inside the container 30 is not limited to a circular shape as long as it matches the outer peripheral shape of the stopper 50 and the container 30 can be closed and moved in the vertical direction.

The cutter 40 includes a plurality of blades. The cutter 40 is a rotary type, and the food material is crushed or the like by a rotating blade. The cutter 40 is arranged on the bottom surface of the recessed portion 21 (the bottom portion of the container 30), and is screwed to the upper end of the shaft body 22 that penetrates the bottom surface of the recessed portion 21 of the pedestal 20 and projects upward.

The plug portion 50 includes a sealing material 51 and a check valve 52. The plug portion 50 is formed in a bottomed columnar shape, has a side wall and a bottom surface, and the side wall has a size suitable for the shape of the inner peripheral wall of the container 30. The plug portion 50 can be inserted and removed from the container 30 with the open end of the side wall as a gripping portion.

The sealing material 51 is formed in an annular shape on the outer peripheral surface of the plug portion 50 on the bottom surface side in one step or in a plurality of steps at appropriate intervals in the vertical direction. The sealing material 51 is made of rubber or the like and is elastically slightly deformed. When the stopper 50 is inserted into the container 30, the sealing material 51 comes into close contact with the inner peripheral surface of the container 30 and seals the opening side of the container 30. Since the stopper 50 is in close contact with the inner peripheral surface of the container 30 within the movable range in the vertical direction in the container 30, it can be fixed at an arbitrary height position. As a result, a closed space is formed in the container 30 by the side wall of the container 30 and the bottom surface side of the plug portion 50. This closed space is referred to as the inside of the container 30, the outer circumference of the container 30, and the side wall opening end side of the stopper 50 as the outside of the container 30.

The check valve 52 includes a substantially disk-shaped valve body 521, a substantially cylindrical valve seat 522, a flange portion 523 provided in a part of the valve seat 522, a spring 524, and a release mechanism 525. There is. The check valve 52 is arranged near the center of the bottom surface of the plug portion 50 and depressurizes the air in the container 30. The check valve 52 may be arranged at a place other than the center of the bottom surface of the plug portion 50 as long as the air in the container 30 can be evacuated.

The valve body 521 has a disk shape and has a release mechanism 525 near the end portion. The valve seat 522 has a substantially cylindrical shape. The collar portion 523 has a disk shape having a hole in the center and is connected to one end of the valve seat 522. When the valve body 521 is crimped to the open end of the valve seat 522 on the side opposite to the flange portion 523, the check valve 52 is closed.

One end of the spring 524 is fixed to the valve body 521, and the other end of the spring 524 is fixed to the flange portion 523. The spring 524 is a tension spring provided so that the valve body 521 is urged to the valve seat 522. Therefore, when the valve body 521 is urged to the valve seat 522, the check valve 52 is closed, the air flow from the outside of the check valve 52 to the inside of the plug 50 is suppressed, and the reverse is true. It works to allow the flow. In other words, the discharge of air to the outside of the container 30 is allowed, and the inflow of air to the inside of the container 30 is suppressed.

The release mechanism 525 forcibly opens the check valve 52 to release the suppression of air inflow. The release mechanism 525 is provided near the end of the valve body 521. The release mechanism 525 is composed of a columnar body protruding toward the open end side of the plug portion 50 and a plate-like body extending in parallel with the valve body 521. When the release mechanism 525 is pulled toward the open end side of the plug portion 50, the valve body 521 moves in the direction away from the valve seat 522 to form a gap, and the valve is opened in which air flows.

The specific operation of the check valve 52 will be described. In the absence of air flow, the valve body 521 is urged to the valve seat 522 and the check valve 52 is closed. When the stopper 50 is pushed into the container 30, the valve body 521 separates from the valve seat 522 due to the pressure of the air in the container 30 going outward, and the check valve 52 floats up to open the check valve 52. The air inside flows out. When the stopper 50 is stopped to be pushed into the container 30, the air flow from the inside of the container 30 is stopped, the valve body 521 is urged to the valve seat 522 by the elasticity of the spring 524, and the check valve 52 is closed. Become. The valve closed state suppresses the flow of air from the outside to the inside, and the pressure inside the container 30 is maintained. When the check valve 52 is opened by the release mechanism 525, the pressure inside and outside the container 30 becomes the same, and the plug portion 50 can be pulled out from the container 30.

The check valve 52 may have any structure as long as the valve closed state and the valve open state can be created. The structure of the check valve 52 is not limited to the structure of the present embodiment, and a known structure can be used.

Next, an example of using the cooking utensil 1 will be described. The pedestal 20 and the container 30 are connected and attached to the main body 10. The foodstuff is put into the container 30, and the open end of the stopper 50 is picked by hand and fitted into the container 30. Pinch the end of the stopper 50 so that the gap between the food and the stopper 50 is narrowed, push it with the palm of your hand, or press the bottom of the stopper 50 with your finger to put the stopper 50 on the bottom of the container 30. Push towards. By narrowing the gap, the amount of air that comes into contact with the food is reduced. Depending on the amount of food, the stopper 50 does not necessarily have to be pushed to the lower limit line. After that, the switch button 11 of the main body 10 is turned on to drive the electric motor to rotate the cutter 40 to crush and cook the ingredients. After the cooking is completed, the valve is forcibly opened by the release mechanism 525 of the stopper 50, and the stopper 50 is removed from the container 30 by pinching the open end portion of the stopper 50 and pulling it up.

The present embodiment has been described above. According to this embodiment, it is possible to provide a cooking utensil 1 capable of reducing oxidation of food with a simple structure. Since the air in the container 30 can be easily evacuated by simply pushing the stopper 50 into the container 30 before cooking, it is possible to reduce the possibility that the foodstuffs come into contact with the air and oxidize during cooking such as crushing.

<Modification example>
FIG. 3 is a diagram showing a schematic configuration example of the cooking utensil 1a according to the modified example of the first embodiment. In this modification, the shape of the plug portion 50a is different from that of the plug portion 50 of the embodiment.

The bottom surface of the plug portion 50a is formed in a pot shape and has a slope from the lower edge portion to the upper central portion. The check valve 52 is arranged near the center of the pot-shaped bottom surface of the plug portion 50a.

With the above configuration, the air in the container 30 can be easily collected in the center of the bottom surface of the plug portion 50a, and the air can be efficiently removed.

4 and 5 are views showing another modification of the first embodiment. In these modified examples, the check valve 52 does not have to be provided with the release mechanism 525, and air holes 60 and 70 that can be opened and closed are provided in a portion different from the release mechanism 525 to create a valve open state. There is. FIG. 4 shows an example in which an air hole 60 is provided on the side surface of the container 30b, and FIG. 5 shows an example in which an air hole 70 is provided on the bottom surface of the plug portion 50b.

In the example of FIG. 4, the air hole 60 is sealed by a plug 61 to prevent air from leaking. Air in the container 30b is evacuated by the stopper 50 to perform cooking such as crushing, and after cooking is completed, the stopper 61 is removed to open the container 30b and air is introduced into the container 30b through the air hole 60. Pull out.

In the example of FIG. 5, the air hole 70 is provided with a lid portion 71 made of rubber or the like inside the stopper portion 50b, with the outside of the stopper portion 50b and the inside of the stopper portion 50b penetrating through the pipe portion 72 such as a rubber pipe. The pipe portion 72 can be sealed.

The check valve 52 of the stopper 50b removes the air from the container 30 to perform cooking such as crushing. After the cooking is completed, the lid 71 is opened to let air into the container 30 through the air hole 70, and the stopper 50b is placed in the container. Pull out from 30.

According to these modifications, air can be evacuated from the openable and closable air holes 60 and 70, so that the check valve 52 can have a simple structure.

FIG. 6 is a diagram showing a schematic configuration example of the plug portion 50c according to another modified example of the first embodiment. 6 (a) to 6 (d) show side sectional views of the plug portion 50c. This modification is different from the plug portion 50 of the first embodiment in that the plug portion 50c is provided with a grip portion 80 on which a finger can be hung.

The plug portion 50c is provided with a grip portion 80 on the open end side of the upper surface. The grip portion 80 may have any shape and material as long as the stopper portion 50c can be easily pulled out from the container 30. For example, a convex portion 81 is provided along the outer circumference of the plug portion 50c on the opening end side (FIG. 6A) to prevent the finger from slipping, or a hole 82 on which the finger can be hooked is provided on the opening end side (FIG. 6A). 6 (b)) may be used. Alternatively, one or two pulling portions 83 of a rod-shaped body or an annular body connected to the bottom surface of the plug portion 50c and extending to the upper surface (open end side) so that the plug portion 50c can be easily pulled out from the container 30 by hooking a finger. It may be provided (FIGS. 6 (c) and 6 (d)).

By providing the grip portion 80, when the stopper portion 50c is pulled out from the container 30, the hands and fingers are less likely to slip from the stopper portion 50c, and the stopper portion 50c can be easily pulled out. The convex portion 81 may be provided along the inner circumference of the plug portion 50c on the opening end side. Further, when the pulling portion 83 is provided, the side wall above the sealing material 51 of the plug portion 50c may be omitted.

<Second Embodiment>
FIG. 7 is a diagram showing a schematic configuration example of the second embodiment. The stopper portion 50d of the present embodiment is different from the first embodiment in that it is a stopper for a cooking utensil used in the existing cooking utensil 2.

The cooking utensil 2 includes a main body 100, a pedestal 200, a container 300, a cutter 400, and a lid 900. The existing cooking utensil 2 may have any configuration as long as the stopper portion 50d of the present embodiment can be used.

The plug portion 50d is formed so that the length of the side wall is shorter than that of the plug portion 50 of the first embodiment. The side wall of the plug portion 50d may be short enough so that the plug portion 50d has a substantially disk shape as long as the plug portion 50d can seal the opening side of the container 300 and bleed air.

The stopper portion 50d is used for the existing cooking utensil 2. After the stopper 50d is pushed into the container 300 of the cooking utensil 2 to remove the air in the container 300, the lid 900 is put on the opening on the upper surface of the container 300 to perform cooking such as crushing. After the cooking is completed, the lid 900 is removed, air is introduced into the container 300 in a valve-opened state by the release mechanism of the check valve 52, and the stopper portion 50d is pulled out from the container 300.

According to the present embodiment, since the stopper portion 50d fits inside the container 300, it can be used for the existing cooking utensil 2. Since the plug portion 50d is formed so that the sealing material 51 seals between the container 300 and the inside of the container 300, the cross-sectional shape inside the container 300 is substantially the same within the movable range of the plug portion 50d. Can be used if.

<Third Embodiment>
FIG. 8 is a diagram showing a schematic configuration example of the third embodiment. The plug portion 50e of the present embodiment is different from each of the above-described embodiments and modifications in that a ventilation pipe 53 is provided instead of the check valve 52. The description will be focused on the points different from the modified example (FIG. 3) of the first embodiment, and the same components will be designated by the same reference numerals and the description thereof will be omitted as appropriate.

The bottom surface of the plug portion 50e is formed in a pot shape like the plug portion 50a. A ventilation pipe 53 is arranged in place of the check valve 52 of the plug portion 50a. The ventilation pipe 53 has a tubular shape and extends above the plug portion 50e to communicate the inside and the outside.

When the stopper 50e is pushed toward the bottom surface of the container 30, the air in the container 30 is released through the ventilation pipe 53. If the container 30 contains a liquid before cooking, the liquid enters the ventilation pipe 53, and the ventilation pipe 53 is blocked to prevent the inflow of air from the outside of the container 30. Since the air in the container 30 can be reduced even when no liquid is contained before cooking, the oxidation of food can be reduced.

A filter such as a mesh may be provided at the entrance / exit portion of the lower end of the ventilation pipe 53 located on the bottom surface of the plug portion 50e so that only air and moisture can pass therethrough. Further, a check valve 52 may be provided at the entrance / exit portion at the upper end of the ventilation pipe 53.

The ventilation pipe 53 of this embodiment can be applied not only to the modified example (FIG. 3) but also to the other embodiments and modified examples described above.

Although the embodiments and modifications of the present invention have been described above, the above-described embodiments and modifications do not limit the invention according to the claims. Based on the above description, those skilled in the art may be able to easily conceive of additional effects and various modifications of the present invention, but the embodiments of the present invention are limited to the above-described embodiments and modifications.
