Description

[Detailed Description of the Invention] [Industrial field of application] The present invention provides a dry storage container for storing dried foods such as paste and powdered seasonings by utilizing the heat absorption and heat generation effects that occur when the thermoelectric element is energized. Regarding the kitchen storage provided.

[Conventional technology]

Foods such as seaweed, rice crackers, and powdered seasonings that are stored in a dry state are stored in cans or closed containers containing silica gel.

[Problems to be solved by the device]

However, if the storage with silica gel is left as it is, the hygroscopic capacity of the silica gel decreases, so it is necessary to renew the silica gel or to dry and regenerate the silica gel. If you fail to do so, the food inside may become moist and useless for a long time.

On the other hand, a conventional dehumidifier that condenses and dehumidifies the moisture in the air with a thermoelectric element is placed in the container to maintain a low humidity inside the container, which is used as a dry storage container for storing food. In this case, there is a problem in that a hot air exhausted from the heat radiation side of the dehumidifier creates a spoilage atmosphere of food.

The same problem arises even in the case where the dry storage container in which the above dehumidifying device is installed is provided in the kitchen storage for storing food and the like.

The present invention has been made in view of the above circumstances, and it is possible to maintain a dry storage container in a low humidity condition well by a dehumidification device using a thermoelectric element, and a dehumidification device in a dry storage container and a kitchen storage container storing it. It is possible to maintain predetermined environmental conditions without creating a spoiling environment due to the heat radiation effect of. It is an object to provide a kitchen storage provided with a dry storage container.

[Means for Solving the Problems]

According to the configuration of the present invention, an opening is provided in a wall of a dry storage container having an opening / closing door, and a water passage through which water flows inside the dry storage with a thermoelectric element sandwiched through the opening. And a cooling body is arranged in the dry storage, and this dry storage container is arranged in the kitchen storage, and means for discharging water condensed on the surface of the cooling body to the outside of the kitchen storage. A water supply pipe connected to a water source arranged outside the kitchen storage is connected to the entrance of the water passage of the radiator, and a drain outlet is arranged outside the kitchen storage at the outlet of the water passage of the radiator. It is characterized in that a discharge pipe is connected.

And, it is preferable to interpose a heat insulator between the radiator and the outer wall surface of the dry storage container.

[Action]

When the thermoelectric element is energized, the surface temperature of the cooling body fixed to the heat absorbing surface of the thermoelectric element eventually reaches the dew point temperature, and the moisture in the air in the dry storage container is condensed on the surface of the cooling body. This condensed water is discharged outside the kitchen storage. The air in the dry storage container is gradually cooled and dehumidified while it goes around the cooling body by natural convection of air, and eventually reaches the target low humidity, and the food in the dry storage container should be stored in a low humidity state. You can On the other hand, the heat generated in the thermoelectric element passes through the radiator fixed to the heat generating surface of the thermoelectric element and is cooled by the flowing water in the water passage provided inside the radiator. In this way, the high heat on the radiator side is transferred to running water and discharged to the outside of the kitchen storage through the drain pipe, so that the dry storage container and the kitchen storage are maintained under predetermined environmental conditions, and the dry storage container and It is possible to prevent spoilage environment for food in the kitchen storage.
Then, by cooling the radiator with water, the cooling efficiency is increased, the dehumidification capacity is excellent, and the inside of the dry storage container can be favorably maintained in a low humidity state.
