In the case of the above-mentioned conventional one, the door is pivotally supported by the refrigerator main body, and the detector which is the electrical component on the door side and the control device which is the electrical component on the refrigerator main body side are connected by a lead wire passing through the pivotal support portion. Yes.
On the other hand, it is conceivable that the same structure is adopted in the doors for the freezer compartment and the vegetable compartment, that is, the drawer-type door, to have the same function.

  However, in the drawer-type door, this moves toward and away from the refrigerator body in parallel, and there is no portion pivoted on the refrigerator body. Therefore, it is impossible to connect the electrical component on the door side and the electrical component on the refrigerator body side with the lead wire passing through the pivotal support part. As a result, the same opening function or opening assistance as the door for the refrigerator compartment It was difficult to provide functions.

  The present invention has been made in view of the above-described circumstances, and therefore an object of the present invention is to provide a storage having an opening function or an opening assist function similar to that of a rotary door even in a drawer type door.

In order to achieve the above object, in the storage of the present invention, a storage body having a storage room, a door for opening and closing a storage product entrance and exit of the storage room, and a drawer operation associated with the movement of the door, A storage container to be taken in and out, an operation responsive mechanism that is provided on the upper side of the door , and that is a mechanical part that is pressed backward by a user operation, and an electromagnetic device that is provided in the storage body, A detector comprising an electrical component facing the lever and provided on a front partition plate of the storage body , and operating the detector when the lever is pressed backward to operate the detector. And the electromagnetic device is excited to separate the door from the storage body (invention of claim 1).

  According to the above means, even in a drawer-type door where there is no portion pivotally supported by the storage body, a desired connection by the electromagnetic device can be achieved without having to worry about the connection between the electrical parts on the door side and the electrical parts on the storage body side. An opening function or an opening assist function can be provided.

Hereinafter, the present invention is applied to a refrigerator, and a first example (first embodiment) will be described with reference to FIGS.
First, in FIG. 2, the whole refrigerator as a storage is viewed from the front, and the refrigerator main body 1 as the storage main body is displayed in order from the top in the refrigerator compartment door 2, the vegetable compartment door 3, the ice making compartment door 4, and the switching. A room door 5 and a freezer room door 6 are provided. Therefore, the refrigerator body 1 is not shown except for the vegetable room 7 shown in FIGS. 1 and 6 to be described later, but a refrigerator room, a vegetable room 7, an ice making room, a switching room, and a freezer room are stored in order from the top. The refrigerator compartment door 2, the vegetable compartment door 3, the ice making compartment door 4, the switching compartment door 5, and the freezer compartment door 6 are stored product entrances and exits (front side of the vegetable compartment 7 in FIG. 1). Only the stored product entrance / exit 7a is opened / closed.

  In this case, in detail, the refrigerator compartment door 2 is a rotary type in which one side of the right side or the left side (right side in the illustrated example) is pivotally supported by the refrigerator body 1, and the vegetable compartment door 3, the ice making compartment door 4 and the switching are made. The room door 5 and the freezer compartment door 6 are each provided integrally with a drawer-type storage container (not shown except for the vegetable room storage container 8 shown in FIGS. 3 and 4 below). It is a pull-out type that moves close to and away from 1 in parallel.

  Here, FIG.3 and FIG.4 has shown the vegetable compartment door 3 and the storage container 8 for vegetable compartments. As apparent from FIGS. 3 and 4, the vegetable compartment door 3 has solid container support members 9 made of, for example, metal on both the left and right sides of the back surface, and stores the storage container 8 for the vegetable compartment. Thus, the vegetable compartment door 3 and the vegetable compartment storage product container 8 are integrated via the container support member 9. A gasket 10 containing a permanent magnet (not shown) is attached to the peripheral edge of the back of the vegetable compartment door 3.

  And as shown also in FIG. 5, the permanent magnet 11 is attached to each rear end of the container support member 9 that faces the rear. On the other hand, 12 indicates an electromagnetic device corresponding to the permanent magnet 11, in this case, an electromagnet, which surrounds the vegetable compartment 7 of the inner box 13 in the refrigerator body 1, as shown in FIG. They are arranged on the left and right sides of the part to be formed (only the left side is shown), that is, on the left and right sides of the back part of the vegetable compartment 7.

  In detail, as shown in FIG. 1, the electromagnet 12 includes, for example, a U-shaped core 14 and coils 17 and 18 wound around bobbin 15 and 16 on the upper side and the lower side, respectively, of the case. 19, the front end of the upper side portion and the front end of the lower side portion of the core 14 function as N and S magnetic poles, respectively. Further, the electromagnet 12 can adjust the magnetic force by changing the voltage applied to the coils 17 and 18, and the adjustment operation is performed on the front portion of the refrigerator compartment door 2 in the refrigerator main body 1. As shown in FIG. 2, it has an operation panel 20 that is an operation unit for performing the operation.

  Thus, rails 21 are formed on the left and right sides of the inner box 13 that surrounds the vegetable compartment 7 (only the left side is shown in FIGS. 1 and 6). A leg wheel 22 provided on the lower side of the rear end of the member 9 is mounted so as to be able to roll, while a receiving wheel (not shown) is provided at the front part of the rail 21, and the container support member 9 is attached thereto. The container support member 9, and thus the storage container 8 for the vegetable compartment, is stored in the vegetable compartment 7 so as to be able to be put in and out of the vegetable compartment 7 in the form of being guided back and forth. It is a drawer type. As a result, the vegetable compartment door 3 is also of the aforementioned drawer type.

Here, the rear end portion 21a of the rail 21 is inclined rearwardly downward, and the container support member 9 is lowered and locked together with the casters 22 so that the storage container 8 for the vegetable compartment is placed in the uppermost position. It is intended to be kept in the storage position on the back side, and this is called a “drop” structure.
Further, when the storage container 8 for the vegetable room is in the above-mentioned storage position, the magnetic pole part of the permanent magnet 11 is opposed to the upper end front end and the lower side front end of the core 14 of the electromagnet 12, that is, the magnetic pole part. I try to touch.

  In contrast to this, FIG. 7 shows the pull-out handle 23, the recess 24, and the support base 25 provided at the center of the vegetable room door 3 on the front side of the upper side. Among them, a support base 25 is incorporated in the vegetable compartment door 3 as shown in FIG. 1, and a handle 23 having an inverted L-shaped cross section is supported by a support shaft 26 of the support base 25 so as to be pivotable back and forth.

  The support base 25 also constitutes an operation responsive mechanism 27. The operation responsive mechanism 27 is pivotally supported on the support base 25 so that a plane L-shaped lever 29 can be rotated back and forth by a shaft 28 shown in FIG. The lever 29 has a receiving portion 29a at a position corresponding to the upper rear end 23a of the handle 23, and a permanent magnet 30 is attached to the rear end portion so that it protrudes to the rear of the vegetable compartment door 3. ing.

FIG. 7 and FIG. 1 also show a front partition plate 31 that partitions between the stored product entrance 7a of the vegetable compartment 7 in the refrigerator body 1 and the stored product entrance of the refrigerated room above it. A detector 32 is incorporated. In this case, the detector 32 is composed of a reed switch, and the permanent magnet 30 attached to the lever 29 is made to correspond to this via a magnetic permeable film 33.
Although not shown, the refrigerator main body 1 is provided with a control device such as a microcomputer that functions to energize the electromagnet 12 based on a detection signal output from the detector 32.

Next, the operation of the above configuration will be described.
First, when the vegetable compartment door 3 is in a closed state, the casters 22 of the container support member 9 are held in the innermost storage position by the “drop” structure described above. At this time, the control device (not shown) also energizes the electromagnet 12 by energizing the magnetic poles of the upper side front end and the lower side front end of the core 14 so that poles different from the magnetic poles of the corresponding permanent magnets 11 appear. Yes. Accordingly, an attractive force is generated between the electromagnets 12 and the permanent magnets 11, whereby the permanent magnets 11 and the container support member 9 are attracted rearward. The storage container 8 for the vegetable compartment is held in the innermost storage position.

  Further, at this time, the gasket 10 of the vegetable compartment door 3 is in close contact with the peripheral portion (including the front partition plate 31) of the stored product inlet / outlet 7a of the vegetable compartment 7 in the refrigerator main body 1 and is brought into close contact with the built-in magnet. Adsorption is held.

  Now, from this state, when the user puts his hand on the handle 23 of the vegetable compartment door 3 and pulls the handle 23, the handle 23 pivots forward as shown by the arrow A in FIG. The receiving portion 29a of the lever 29 in the operation responsive mechanism 27 is pushed backward by the upper rear end 23a. As a result, as shown by the arrow B in FIGS. 1 and 7, the lever 29 rotates rearward about the shaft 28, and the permanent magnet 30 attached to the rear end is brought close to the detector 32. Based on this, a control device (not shown) energizes the electromagnet 12 in the opposite direction to the above to excite it.

Therefore, at this time, the electromagnet 12 represents the same pole as the magnetic pole of the corresponding permanent magnet 11 at each of the magnetic poles of the upper side front end and the lower side front end of the core 14, thereby generating a repulsive force. As a result, the permanent magnet 11 and, by extension, the container support member 9 attached to the rear end thereof are pushed forward together with the storage container 8 for the vegetable compartment and the vegetable compartment door 3. By this extrusion, the caster 22 is removed from the “drop” structure described above, and the gasket 10 is separated from the peripheral part of the stored product entrance of the vegetable compartment 7.
Therefore, after that, the stored product container 8 can be pulled out as desired integrally with the vegetable compartment door 3 by continuously pulling the vegetable compartment door 3 with the hand placed on the handle 23 by the user.

  And in order to make it function as mentioned above, in the thing of this composition, electric parts called electromagnet 12 and detector 32 are provided only in refrigerator main body 1, and handle 23 and operation responsive mechanism 27 are provided on the vegetable compartment door 3 side. Only mechanical parts are provided. Therefore, even in the drawer-type vegetable compartment door 3 where the portion pivotally supported by the refrigerator main body 1 does not exist, the above-mentioned connection is made without difficulty in connecting the electrical components on the vegetable compartment door 3 side and the electrical components on the refrigerator main body 1 side. The desired opening function or opening assist function by the electromagnet 12 can be provided.

  Moreover, in this case, since it is not necessary to connect the electrical component on the vegetable compartment door 3 side and the electrical component on the refrigerator body 1 side, the lead wire for the connection and the connection work can be abolished. It can contribute to reduction.

  In addition, in the case of this configuration, the electromagnet 12 always keeps the vegetable storage door 8 in the storage position by bringing the vegetable storage door 3 toward the refrigerator body 1 side except when the vegetable storage door 3 is pulled out. Thereby, the vegetable compartment door 3 can be more securely fastened in the closed state, and the stored product container 8 can be more securely fastened in the storage position.

Further, in the case of this configuration, the electromagnet 12 enables adjustment of the magnetic force that separates the vegetable compartment door 3 from the refrigerator main body 1, whereby the user tries to open the vegetable compartment door 3 (stored product container 8 The optimum opening force by the electromagnet 12 can be obtained in accordance with a light weight sensation (which depends on the total mass of the stored product stored in the storage product container 8).
In this case, the weight of the storage container 8 may be detected by a weight sensor or the like, and the magnetic force of the electromagnet 12 separating the vegetable compartment door 3 from the refrigerator body 1 may be automatically adjusted.

  As described above, in the configuration in which the electromagnet 12 always moves the vegetable compartment door 3 to the refrigerator body 1 side except when the vegetable compartment door 3 is pulled out, the storage container 8 is held in the storage position. By this, the vegetable compartment door 3 can be more securely fastened in the closed state, and the storage product container 8 can be more securely fastened in the storage position, and thus the rail 21 that guides the storage product container 8 so that it can be taken in and out. Moreover, since the user does not have to pull out the vegetable compartment door 3 (stored product container 8) against this, it is not necessary to pull out the stored product container 8 into the storage position. Can be further reduced.

[Third embodiment]
In the third embodiment shown in FIGS. 9 and 10, the permanent magnet unit 41 is provided on the left and right sides of the back of the vegetable compartment door 3 or one side thereof instead of the permanent magnet 11 described above, and the electromagnet 12 is provided. The refrigerator body 1 is provided at the front part of the left and right inner side surfaces of the part that forms the surroundings of the vegetable compartment 7 of the inner box 13 or at the front part on one side thereof.
The permanent magnet unit 41 is constructed by attaching permanent magnets 43 and 44 to upper and lower ends of a yoke 42 made of a magnetic material such as iron and housing them in a case 45.
Even if it does in this way, the effect similar to the above-mentioned can be acquired.

In addition, the electromagnetic device illustrated by the electromagnet 12 is not restricted to what pushes out the vegetable compartment door 3 by the repulsive magnetic force with the permanent magnet 11, For example, it has a movable core and pushes out the vegetable compartment door 3 by it. It may be a thing.
