Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a refrigerator in which a refrigerated item can be arbitrarily taken in and out, and energy loss caused when the refrigerated item is taken in and out can be minimized.

[0002]

[Prior art]

 Conventionally, refrigerators have become large in size and have come to store many types of refrigerated items. It is difficult to know the intended storage location for refrigerated items, and it is often the case that multiple doors are opened for viewing. 2. Due to the large depth of the storage area, it is difficult to see what is behind and it takes time to find and retrieve it. 3. The door of the refrigerator is a rotating type with one side as its axis, and its large area causes a large amount of sucked air and a large loss of thermal energy due to opening and closing. 4. You have to use your hands to open and close the door, which is a problem when you have an item. There were structural defects.

[0003]

[Problems to be solved by the device]

 The idea of this invention is in a refrigerator: It is not necessary to decide the place to store refrigerated items by type and search for it. 2. The depth of the refrigerated article storage section is small and the inside can be easily seen. 3. When opening and closing the refrigerator, the loss of heat energy is extremely small. 4. With the remote control panel, you can easily select the shelves for putting refrigerated items in and out. 5. The remote control panel automatically opens and closes the door, eliminating the need for manpower. 6. The automatic sensing equipment closes the door so that no human labor is required and you will never forget to close it. The purpose is to provide a convenient and useful refrigerator as described above.

[0004]

[Means for Solving the Problems]

 The refrigerator of the present invention has a cylindrical shape in which one corner of the rear part is a right angle. The part forming the right angle shall be the passage for the refrigerant gas and the place for housing the refrigerating machine. If there is not enough room for the refrigeration machine, use the bottom of the refrigerator for this.

Most of the inside of the refrigerator having a cylindrical shape is occupied by multistage shelves which are electrically rotated about the vertical center line of the cylinder. All the shelves are divided into three equal parts and separated by partition walls. The vertical distance between shelves should be approximately 13 to 40 cm, depending on the size of the refrigerated items envisioned.

A window corresponding to the frontage of the shelf is provided at the front of each step, and an electric sliding door matching the size of the window is attached to the outside of the window. There is one door for each step, and it slides horizontally in a gutter provided along the outer circumference of the refrigerator. The windows and doors are kept airtight by the seal material, but this seal material sinks by electromagnetic action immediately before the door slides, and prevents friction when sliding. If the door returns to the window, the submerged sealing material will automatically return to its original purpose of maintaining airtightness.

The operation panel has a built-in dry battery and has a large number of push buttons. By pushing these buttons, the rotation of the shelf and the opening of the door can be simultaneously performed electrically. Enter the name of the refrigerated item stored in each of the divided shelves on the push button. Those who use the refrigerator can arbitrarily rewrite these entries. It is desirable that the operation panel be provided with a time display.

[0008]

[Embodiment of the invention]

 Hereinafter, details of the embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an external appearance of a refrigerator according to the present invention, in which a rear right corner 2 of a refrigerator main body 1 accommodates a passage for a refrigerant gas and a part of a refrigerating machine. The other parts of the refrigeration machine are stored in the lower part 3 of the refrigerator. A height adjuster 4 is attached to the outermost bottom of the refrigerator to keep the refrigerator horizontal and vertical. In FIG. 1, one of the doors 6 is removed for the sake of explanation, and the shelf 5, the window 7, the partition wall 8 and the sealing material 10 are shown. In this embodiment, the shelves 5 and the doors 6 corresponding thereto have seven steps, but the number of these steps can be arbitrarily changed.

FIG. 2 is a perspective view showing an example of the structure of the shelf 5. The shelf 5 divided into three equal parts by the partition wall 8 is electrically rotated about the cylindrical vertical center line of the refrigerator body 1 as the axis 9. The height of the shelf 5 is approximately 13 to 40 cm depending on the size of the refrigerated article, and a support suitable for the shape of the refrigerated article can be provided inside the shelf 5.

The door 6 can be electrically slid sideways to open a window 7 having a width of the front of the shelf 5 so that refrigerated articles can be taken in and out. The door 6 has a structure that is highly heat-retaining in order to suppress the loss of refrigeration energy. A sealing material 10 is attached along the outer edge of the window 7 to maintain airtightness with the door 6. Immediately before the door 6 starts sliding, the sealing material 10 automatically sinks by electromagnetic action so that frictional force does not work between the inner surface of the door 6 and the outer surface of the window 7. When the door 6 returns to the position of the window 7, the submerged sealing material 10 automatically floats, and the purpose of maintaining airtightness is achieved. In order to support the door 6 when it slides, a gutter 11 is provided above and below the door 6 along the outer circumference of the refrigerator body 1.

The refrigerator of the present invention is opened and closed using a remote control panel, an example of which is shown in FIG. The operation panel has a built-in dry battery and a small electronic calculator, and has three times as many push buttons as there are shelves. A sticker with the name of the refrigerated item selected by the user is attached to this push button. The refrigerated article names shown in FIG. 3 are examples thereof. When the user presses the button for the name of the desired refrigerated item, the shelf 5 is rotated, the portion for accommodating the desired refrigerated item is stopped forward, and the corresponding door 6 is opened, so that it can be taken in and out.

The refrigerator is provided with a human approach sensing function, and the door 6 is automatically and electrically closed by sliding immediately after the human leaves.

[Effect of the invention]

 According to the present invention, since it is configured as described above, it is possible to provide a refrigerator that is convenient and saves the user's labor and consumes less electric energy as described below.

There is no need to search because it is possible to determine a place to store refrigerated items for each type.

The depth of the refrigerated article storage shelf is small and the inside can be easily seen.

The loss of thermal energy when opening and closing the refrigerator door is extremely small.

It is possible to easily select a shelf for storing refrigerated articles by using the remote control panel.

The door can be automatically opened and closed by the remote control panel, and no human labor is required.

The human proximity detection facility closes the door so that no human labor is needed and it is not forgotten.
