The air inlet 21 opens the on-off valve 20 and introduces air when the inside of the pressure-resistant container 5 is returned to the atmospheric pressure before the chamber lid 6 is opened after the vacuum packaging is completed. The switching valve 18 is constituted by, for example, a three-way valve, and a suction hose 22 is connected to one of the switching paths. The suction hose 22 has a suction nozzle 26 attached to a tip end thereof, and is a hose that can be connected to the exhaust port 31 of the vacuum storage container 30 as shown in FIG. With the suction nozzle 26 of the suction hose 22 pressed against the exhaust port 31 of the vacuum storage container 30, the switching valve 18 is connected to the suction hose 22.
By switching to the side and operating the vacuum pump 7,
The pressure inside the vacuum storage container 30 is reduced. This suction hose 2
2 and a suction nozzle 26 at the tip thereof are housed in a hose housing 25 installed on the side surface of the housing 2.

The vacuum storage container 30 illustrated in FIG. 5 has a stainless steel box-shaped container body 32 having an opening on the upper surface.

Thereafter, when the chamber lid 6 is closed, a switch (not shown) for detecting the open / closed state of the chamber lid 6 is turned on, whereby the vacuum pump 7 starts operating, and the pressure-resistant container 5
The pressure inside is reduced to near vacuum. When the pressure inside the pressure-resistant container 5 is reduced, the sealing material at the lower edge of the peripheral portion of the chamber lid 6 is more tightly adhered to the lower chamber 4, so that the airtightness is sufficiently ensured.

When the pressure inside the pressure-resistant container 5 is reduced to near the vacuum, the lower heater block 9a of the sealing device 9 rises, and the opening portion of the packaging bag 3 is sandwiched between the lower block 9a and the upper block 9b. The mouth is sealed by heat sealing. After a few seconds, turn off the hot wire and lower the lower heater block 9a,
After the operation of the vacuum pump 7 is stopped, the on-off valve 20 is opened. When the on-off valve 20 is opened, the atmosphere is introduced into the pressure-resistant container 5 from the air inlet 21, thereby returning the inside of the pressure-resistant container 5 to the atmospheric pressure. Therefore, the vacuum packaging is completed in this state, the chamber lid 6 is opened, and the vacuum-packaged packaging bag 3 can be taken out.

Next, the case where the composite vacuum cooking appliance 1 of the present embodiment is used as a heating cooker will be described. First,

It can be used without worry, as in the case of a conventional cooking device.

The preset temperature is controlled by a control device (not shown) so as to be maintained at a constant temperature. In the case of performing vacuum cooking, the temperature varies depending on the food material, but if the temperature is set to approximately 60 ° C. to 90 ° C., cooking can be performed quickly without impairing the flavor of the food material. The variation with respect to the set temperature is controlled to be within ± 1 ° C.

When used for general cooking, the temperature is set, for example, in the range of 150 ° C. to 250 ° C. in accordance with the cooking method of boiling or baking. In this case, even if the variation with respect to the set temperature is larger, it is permissible, but when cooking fried food such as tempura, the temperature of the oil can be controlled more accurately than with a gas stove, so that it is possible to cook deliciously.

Next, a case where the composite vacuum cooking appliance 1 of the present embodiment is used as a pressure reducing means for the vacuum storage container 31 will be described. First, the “vacuum vessel mode” on the operation panel 10
Select When the inside of the vacuum storage container 31 in which the object to be preserved is put and the lid is closed is depressurized or evacuated, the suction hose 22 is pulled out from the hose storage part 25 from the hose storage part 25, and the suction nozzle 26 at the tip is closed. The connection is made by pressing against the exhaust port 31 of the member 33. When the operation of the vacuum pump 7 is started in this state, the check valve 38 provided on the lid member 33 is sucked, the check valve 38 is opened, and the pressure in the vacuum storage container 31 is reduced to near vacuum. When the pressure is reduced to near the vacuum, the operation of the vacuum pump 7 is stopped, and the suction nozzle 26 is separated from the exhaust port 31. When the pressure in the vacuum storage container 31 is reduced in this manner, the check valve 38 is thereafter moved to the container 3.
Since the pressure difference between the inside of 1 and the atmosphere is strongly pressed against the tapered inner peripheral surface of the exhaust port 31 to maintain a sealed state, the inside of the vacuum storage container 31 can be kept in a reduced pressure state.

According to the composite vacuum cooking appliance 1 of the present embodiment having such a configuration, the lower chamber 4 for accommodating the packaging bag 3 for accommodating articles to be packaged, such as food, and the chamber lid 6 for covering the upper part thereof. The pressure vessel 5 is partitioned and formed, and the inside of the pressure vessel 5 is depressurized by the vacuum pump 7 through the exhaust port 8.
