Description

  The present invention relates to a vacuum storage pan that can store, for example, a cooked food under vacuum.

  The vacuum storage container has a closable chamber lid on the lower chamber, and has a pressure-resistant container that accommodates a packaging bag that accommodates an object to be packaged, and an interior through an exhaust port disposed in the pressure-resistant container. A vacuum pump for depressurization, a sealing device that is disposed in the pressure-resistant container and seals the opening of the packaging bag, and a heating unit that is disposed on the bottom surface of the lower chamber and heat-treats the vacuum package. A composite vacuum cooking apparatus is disclosed (Japanese Patent Laid-Open No. 2002-159397).

  In addition, in a vacuum storage container having a container main body for storing stored items and a lid member for sealing the container main body, a check valve that allows ventilation from the inside to the outside but prevents the reverse, and an internal negative A vacuum storage container provided with an indicator for displaying the ratio of pressure is disclosed (Japanese Patent Laid-Open No. 2001-158474).

Furthermore, a vacuum storage container with a check valve having a structure having a vacuum suction port with a check valve is used as the container, and the cooked food is stored in the vacuum storage container. A method of evacuating a chamber is disclosed (Japanese Patent Laid-Open No. 2003-215).
JP2002-159397, JP2001-158474, JP2003-215

  However, these vacuum storage containers are designed to maintain the internal vacuum state by providing a check valve or the like at the exhaust port, but the internal vacuum state can be maintained completely only by providing the check valve. I can't.

  In view of this, the present invention comprises a main body and a lid, and an air intake passage in the main body having an exhaust pump connection port at one end is formed in the lid, and an electromagnetic valve is interposed in the intake passage. A vacuum storage pan with a ball valve mounted on the exhaust port connected to the main body is proposed.

  That is, in the present invention, for example, cooked food is stored in the main body, the lid is closed, an exhaust pump such as a vacuum pump is connected to the connection port of the intake passage, the electromagnetic valve is opened, and the air in the main body is opened. When air is sucked in through the intake passage, the ball valve placed on the exhaust port is lifted by the suction force of the vacuum pump, and the air in the main body is exhausted from the exhaust port through the intake passage, and the inside of the main body is appropriately vacuumed. When the solenoid valve is closed, the ball valve sinks and closes the exhaust port.

  Therefore, in this invention, after the intake passage is closed by the electromagnetic valve, the exhaust port is closed by the ball valve, so that the vacuum state in the main body is maintained, and the cooked food stored in the main body is kept for a long time. Vacuum storage.

  The ball valve used for the check valve has been made of stainless steel (specific gravity 8). However, the titanium valve (specific gravity 4.5) can be used to handle the opening and closing of the solenoid valve. Is possible.

  The electromagnetic valve can be controlled manually while looking at the pressure gauge provided in the intake passage, but may be controlled directly by the pressure in the intake passage.

  It consists of a storage pan body and a lid, and in the lid is formed an air intake passage in the body with a connection port of a vacuum pump at one end, and an electromagnetic valve and a pressure gauge are interposed in the intake passage, A titanium ball valve is placed at the exhaust port connected to the main body, an air supply pipe inserted into the main body is provided on the lid, and an air supply valve is provided at the outer end of the air supply pipe.

  Hereinafter, the present invention will be described in detail with reference to the illustrated embodiments. Reference numeral 1 denotes a storage pan body, 2 denotes a lid, a fixed grip 3 is provided between the body 1 and the lid 2, and A heat-resistant (160 ° C.) hermetic packing 4 is fitted to the inner periphery of the lid 2 in contact with the upper edge.

  On the other hand, an air intake passage 7 in the main body 1 having a connection port 6 for the vacuum pump 5 at one end is formed in the lid 2.

  An electromagnetic valve 8 and a pressure gauge 9 are interposed in the intake passage 7, and a titanium ball valve 11 is placed in the exhaust port 10 connected to the main body 1.

  The lid 2 is provided with an air supply pipe 12 inserted into the main body 1, and an air supply valve 13 is provided at the outer end of the air supply pipe 12.

  In this embodiment, among the members provided on the lid 2, the heavy solenoid valve 8, pressure gauge 9, etc. are housed in a stainless steel box 14, and the upper part of the air supply passage 7 is the main body of the lid 2. Separable from 2a.

  Further, adapters 15 and 15 are provided between the separated ends of the air supply passage 7, and a cradle 16 for the box 14 is provided on the main body 2 a of the lid body 2. The main body 2a is connected to the main body 2a by the adapters 15 and 15 and the air supply passage 7 on the box 14 side. A power supply connector 17 for the electromagnetic valve 8 is provided in the box 14.

  In the above configuration, in use, for example, the cooked Chinese food is closed in the storage pan body 1 with the lid 2 closed, and the connection port 6 is connected with a moisture collection trap 18 and a moisture absorption box 19 filled with a dryer or the like. Then connect the vacuum pump 5.

  Next, when the electromagnetic valve 8 is opened and the vacuum pump 5 is operated to suck the air in the main body 1 through the intake passage 7 and the inside of the main body 1 is in an appropriate vacuum state while looking at the pressure gauge 9, the electromagnetic valve When 8 is closed, the ball valve 11 sinks and closes the exhaust port 10.

  For this reason, in this invention, the vacuum state of the main body 1 is maintained, and the cooked food stored in the main body 1 can be vacuum-stored for a long period of time.

  When the lid 1 is opened while the main body 1 is in a vacuum state, air may be sent into the main body 1 through the air supply pipe 12 to release the vacuum state in the main body 1.

  In short, according to the present invention, a vacuum storage pan can be provided that maintains the vacuum state in the main body with a simple structure and enables long-term storage of cooked food.
