Abstract

PURPOSE:To enable to homogenize the taste of a pickle in simple operations by combining an electrically operated vacuum pump, an electrically operated switch valve and a control means in a specific action state. CONSTITUTION:Atmospheric air is fed into a container from an opening 35 through a communication pipe 26 to increase the pressure in the container to the atmosphere, whereby a soup is impregnated into air-removed tissues and into cellular membrane-decomposed cells. When the output of electric current from a single stabilizing multi-vibrator 45 is stopped, the operation of a relay 44 is stopped and a relay switch S is closed. The closure of the relay switch S causes the operation of a solenoid 35, the transfer of a valve 34 from the chain line position to the continuous line position and the closure of the opening 33 of a bottomed cylinder 32, whereby air in the container is again removed to evacuate the container. The operations are repeated only for a prescribed time to prepare pickles.

It is equipped with a vacuum pump 6 that evacuates the air inside the container 1 in the direction of the arrow by moving the vacuum pump 6, and an on-off valve 8 that sets the inside of the container 1 to atmospheric pressure by operating a knob 7.

When making pickles, first of all, the lever 5 is moved up and down. Then, the vacuum pump 6 creates a negative pressure inside the IFl #1, which causes the air trapped between the tissues of the material placed in the container 1 to escape and the cell membrane of the material to be destroyed. Operate and enjoy! ! ! Bring the inside of 1 to atmospheric pressure. Then, the juice placed in the container 1 seeps into the spaces between tissues where air has escaped and into cells whose cell membranes have been destroyed.

By repeating these operations, pickles can be made in a short time.

(Problems to be Solved by the Invention) However, in the conventional device, the lever 5 and the knob 7 had to be operated manually, which was extremely troublesome. Furthermore, since the degree of vacuum inside the container 1 is determined by the number of times the lever 5 is operated and the force with which the lever 5 is pressed, it is difficult to always make pickles with a constant degree of vacuum. There was also the problem that the taste was different and it was difficult to make the taste uniform.

The vacuum cooking device is equipped with an airtight lid and an electric vacuum pump that removes air from the container that is placed in the receiving portion of the main body, and the IF device is heated to atmospheric pressure when opened. and a control means for intermittently operating the electric vacuum pump and the electric on-off valve so as to close the electric on-off valve when the electric vacuum pump is operating. It is characterized by

Further, the vacuum cooking device includes a main body having a receiving part for placing a container thereon, and a sealing lid configured to seal an opening of a container placed on the receiving part, an electric vacuum pump that removes air from a container placed in the container; an electric on-off valve that brings the inside of the container to atmospheric pressure when opened; The apparatus is characterized in that the main body is provided with a control means for alternately opening and closing the on-off valve to alternately set the inside of the container to negative pressure and atmospheric pressure.

(Operation) Since the present invention has the above-mentioned configuration, the control means operates the electric vacuum pump and the electric on-off valve intermittently, and the inside of the container is alternately moved under negative pressure by the intermittent operation of the electric vacuum pump and the electric on-off valve. pressure and atmospheric pressure.

Further, while the electric vacuum pump is operating, the control means controls the electric on-off valve to alternately open and close the electric on-off valve, whereby the inside of the container is alternately brought into negative pressure and atmospheric pressure.

(Example) Hereinafter, an example of the vacuum cooking device according to the present invention will be described based on the drawings.

In FIGS. 1 and 2, 11 is a vacuum cooking device main body, and an electric vacuum pump 12 is provided inside this main body 1, and vibration is generated between this electric vacuum pump 12 and a bottom plate 13 of the main body 11. A buffer member 14 is interposed to absorb the . Further, the main body 11 is provided with a timer (control means) 10 for driving the electric vacuum motor 12 for a set time. D is a dial (setting means) for setting the driving time.

A receiving part 16 on which a container 15 is placed is formed on the upper surface of the main body 11, and a columnar holding part 17 extending upward is provided from the vertical upper surface adjacent to the receiving part 16.

One end of the sealing lid 18 is pivotally supported by mJ on the upper part of this holding part 17, and the sealing lid 18 can be rotated around the axis J, and the other end of the sealing lid 18 can be moved downward. By pressing, the opening 19 of the container 15 placed on the receiving part 16 can be sealed.

The seal 1118 consists of a top plate part 21 and a bottom plate part 22,
An annular seal holding portion 23 is formed on the lower surface of the bottom plate portion 22, and a sealing member 24 that contacts the upper end 15a of the container 15 is held in the seal holding portion 23. The container 15 is sealed by this seal member.

A communication hole 25 is provided in the bottom plate portion 22, and one end of a communication pipe 26 is connected to the communication hole 25. Communication pipe 2
6 passes through the sealing lid 18 and the holding part 17 to the main body ll.
The other end is connected to an electric vacuum pump 12 provided inside the main body 11.

An electric on-off valve 31 is provided in the middle of the communication pipe 26, and as shown in FIG. 33
It consists of a valve body 34 that closes the valve body, a solenoid 35 that moves the valve body 34 up and down, and the like.

The valve body 34 is urged upward by a spring 38,
The bottomed cylinder 3 is always located at the chain line position.
2 is kept in communication with the atmosphere.

Furthermore, when the solenoid 35 is actuated, the valve body 34 moves downward against the spring 38 and closes the opening 33.

Communication holes 36 and 37 are formed in the lower part of the bottomed cylindrical body 32, respectively, and these communication holes 36 and 37 communicate with the electric vacuum pump 12 and the inside of the container 15 via the communication pipe 26.

In addition, in FIG. 1.2, K is a rubber leg provided at the bottom of the main body 11.

FIG. 4 shows an electric circuit for driving the electric on-off valve 31 and the electric vacuum motor 12. In FIG. 4, 40 is a control circuit (control means) for controlling the electric on-off valve 31. is an oscillation circuit 41 that periodically outputs a pulse P shown in FIG. 0M is a main switch, and TS is a main switch, which is equipped with a monostable multivibrator 43 that operates to flow a current for a certain period of time T, and a relay circuit 44 that opens a relay switch S by the current output from the monostable multivibrator 43. This is a timer switch that is closed by a timer 10.

The oscillation circuit 41 generates a pulse P by an external variable resistor 45.
The period T2 of the monostable multivibrator 43 can be adjusted using an external variable resistor (adjustment means) 4.
6 allows the current output time T to be adjusted. Further, by changing the setting of the count number of the counter 42, the period T3 of the pulse R can be changed.

Next, the operation of the vacuum cooking device of the above embodiment will be explained.

First, @@15 containing material Z and juice Q is set in the receiving part 16 of the main body 11 as shown in FIGS. 1 and 2. F is a weight plate that prevents the material from floating up.

Next, the driving time is set using the dial D of the timer 10, and the main switch M is turned on. Then, the timer switch TS is closed by the timer 10, so
The solenoid 35 of the electric on-off valve 31 is actuated, the valve body 34 moves downward against the spring 38, and the valve body 33 closes the opening 33 of the bottomed cylinder 32. That is, the electric on-off valve 31 is closed.

On the other hand, when the main switch is turned on, electric vacuum pump 1
2 is activated and the opening 33 of the bottomed cylinder 32 is closed by the valve body 33, so the air inside the container 15 is removed.
As a result, the inside of the container 15 becomes a negative pressure, and air escapes from between the tissues of the material 2 and the cells of the material are destroyed.

On the other hand, the oscillation circuit 41 outputs a pulse P with a predetermined period as shown in FIG. 5, and the counter 42 counts the pulse P and divides the pulse P into a pulse R with a predetermined frequency and outputs the pulse P. Then, the monostable multivibrator 43 outputs a current for a certain period of time at the falling edge of the pulse R. The relay switch S is opened by the second current, and the solenoid 3 of the electric on-off valve 31 is opened.
5 stops, the valve body 33 is raised to the chain line position by the spring 3B, and the opening 33 of the bottomed cylinder 32 is unsealed (time t1), that is, the electric on-off valve 31 is opened. becomes.

Atmospheric air flows from this opening 33 to the container 15 via the communication pipe 26.
The inside of the container 15 becomes atmospheric pressure. This allows the juice to seep into the spaces between the tissues where air has escaped and into the cells where the cell walls have been destroyed.

When the output of current from the monostable multivibrator 43 is stopped (time t2), the operation of the relay 44 is stopped and the relay switch S is closed. Closing the relay switch S activates the solenoid 35, moves the valve body 34 from the chain line position to the solid line position, and the opening 33 of the bottomed cylinder 32 is closed. Due to this blockage, the air inside the container 15 is removed again, and the inside of the container 15 becomes negative pressure.

These operations are repeated for the time set by the timer to make pickles.

Once the pickles are made, turn off the main switch M. Then, the electric vacuum pump 12 stops operating, the solenoid 35 of the electric on-off valve 31 stops operating, and the electric on-off valve 31 is opened. This opening brings the inside of the IF vessel 15 to atmospheric pressure, making it easy to remove the seal M18 from the container 15.

In this way, the air in the container 15 is automatically removed by the electric vacuum pump 12, and the electric on-off valve 31 is opened and closed automatically, so there is no need to manually operate the vacuum pump or the on-off valve as in the past. This is not necessary and is very convenient.

Furthermore, since air is removed by the electric vacuum pump 12, the degree of vacuum inside the container 15 does not vary depending on the operator, and therefore the taste of the pickles can be made uniform. In addition, since the negative pressure time and the atmospheric pressure time that are alternately repeated can be adjusted using the variable resistors 45 and 46 and the counter 42, it is possible to make pickles that are suitable for the material 2.

In the above embodiment, the electric vacuum pump 12 is not operated intermittently in order to alternately bring the inside of the container 15 to negative pressure and atmospheric pressure, so there is no possibility of overloading the electric vacuum pump 12. .

In FIG. 6, the operation of the electric vacuum pump 12 is stopped when the electric on-off valve 31 is opened. That is, the operation of the electric vacuum pump 12 is stopped when the inside of the container 15 is brought to atmospheric pressure. This is done by simultaneously opening and closing the relay switches S and S- using the relay 44. In this embodiment, since the operation of the electric vacuum pump is stopped when the electric on-off valve 31 is opened, the inside of the container 15 quickly reaches atmospheric pressure. The rest is the same as the above embodiment, so the explanation thereof will be omitted.

(Effects) According to this invention, there is no need to manually operate a vacuum pump or an on-off valve, and pickles can be made with very simple operations, and the taste of the pickles can be made uniform. .

Furthermore, when the electric vacuum pump is in operation, the electric vacuum pump is equipped with a control means that alternately opens and closes the electric on-off valve to alternately create negative pressure and atmospheric pressure in the container. There is no need to operate the electric vacuum pump intermittently, so there is no need to overload the electric vacuum pump.
