Description

  The present invention relates to a refrigerator, and more particularly to a door opening / closing configuration such as a cold storage room.

  In general, a home refrigerator includes a refrigeration room, a vegetable room, a freezing room, and the like, and the chilled room is cooled to a temperature lower than that of the refrigerated room (a temperature range of about 1 ° C. lower than that of the refrigerated room). Room) or a partial room (a room having a slight freezing temperature range of about −3 ° C.) or a low temperature storage room such as a third temperature zone room which can be switched to these can be seen.

  And the said low-temperature storage chamber is provided with the container which can be taken in and out, and the door of the said low-temperature storage chamber is opened and closed by taking in and out of the said container (for example, refer patent document 1).

  FIG. 12 shows a refrigerator described in Patent Document 1. This refrigerator is provided with a low-temperature storage chamber 102 in the lower part of the refrigerator compartment 101, and the low-temperature storage compartment 102 can be used as a shelf plate positioned at the lowermost stage of the refrigerator compartment 101. The shelf board member 103 to be used is covered.

  The low-temperature storage chamber 102 is provided with a container 104 that can be pulled out, and an inclined portion 105 is provided at the front opening edge portion. When the container 104 is taken in and out, the inclined portion 105 comes into contact with a protrusion 107 provided on the back surface of the door 106 to open and close the door 106.

JP 2006-118825 A

  According to the door opening / closing configuration described in Patent Document 1, the door 106 can be opened / closed simply by inserting / removing the container 104, and there is no need to manually open / close the door 106 when inserting / removing the container 104. There is an advantage that it is good.

  However, the configuration described in Patent Document 1 has the following problems. That is, the force required to put in and out the container 104 is affected by the inclination angle of the inclined portion 105 provided in the container 104. If the inclination angle is close to the vertical, the component force in the direction of opening the door 106 is reduced and a large force is applied. The container 104 becomes heavy.

  On the other hand, when the container 104 is pushed in and stored close to the horizontal, the component force in the container storing direction obtained by the weight of the door 106 is reduced and a large container pushing force is required.

  Accordingly, the inclined portion 105 of the container 104 is set to an eclectic inclination angle in consideration of these points, but it is slightly heavier both when the container is pulled out and when it is pushed in and stored, so that it is easy to use. It was.

  In particular, when the container 104 is started to be pulled out, that is, at the initial stage of pulling out (operation), since a large force is instantaneously required in terms of mechanics, it is felt heavier with the addition of the large force required instantaneously. Tended to give the impression that it was not good.

  As a result, the weight of the door 106 tends to be reduced as much as possible. Therefore, the thickness of the transparent plate or the like used for the door 106 is reduced, resulting in a decrease in quality, and at the same time, the door load applied when the container is pushed in. As a result, the container pushing force due to the force was reduced, which further promoted the poor container push-in storage property.

  This invention is made | formed in view of such a point, and it aims at provision of the refrigerator which improved the convenience of taking in and out and improved the usability.

  In order to achieve the above object, the present invention is configured such that the inclined portion that opens and closes the door includes two or more inclined portions having different inclination angles along the container moving direction.

  As a result, the component force used for opening and closing the door or moving the container when the container is taken in and out can be set to a different size depending on the angle of the inclined portion, and can be set to a size suitable for the position when the container is taken in and out. it can. Accordingly, it is possible to reduce the pulling force of the container and at the same time to set the operation force when the container is pushed in and stored, thereby greatly improving usability.

  According to the above configuration, the present invention can provide an easy-to-use refrigerator with improved container insertion and removal.

When the door 11a is opened, the light is turned on and the inside of the refrigerator compartment 7 is irradiated.

  Further, the refrigerator compartment 7 is formed with a low temperature storage compartment 23 in the lower part thereof. The low-temperature storage chamber 23 is a low-temperature storage chamber that can be switched to a chilled chamber cooled to a temperature zone of about 1 ° C. or a partial chamber cooled to a slight freezing temperature zone of about −3 ° C., for example. The low temperature storage room 23 is not switchable to a chilled room or a partial room, but may be designed exclusively for a chilled room or a partial room.

  As shown in FIGS. 4 to 6, the low-temperature storage chamber 23 has a shelf member 24 that uses the upper surface as a shelf located at the bottom of the refrigerator compartment 7, and a water supply tank chamber 22 (see FIG. 2) on the side surface. The container 25 is partitioned by a partition plate 22a, and a container 25 that can be pulled out is provided inside, and the front of the container 25 is rotated around the front end of the shelf plate member 24 by the container 25 being pulled out. The door 26 is then closed.

  Hereinafter, the opening / closing configuration of the door 26 will be described with reference to FIGS.

  First, as shown in FIGS. 4 to 6 and particularly FIGS. 9 and 10, the container 25 is formed in a substantially box shape having an upper surface and an upper front opening, and a handle 25 a is integrally formed at the front end. A guide piece 27 for opening and closing the door 26 is provided in a strip shape on the outer surface of both side walls.

The guide piece 27 is formed with an inclined portion 28 for opening and closing the door 26. In this example, the inclined portion 28 is composed of two inclined portions 28a and 28b, and the intermediate portion is connected by a horizontal piece portion 28c, and the inclination angles are set to different angles.

  In the present embodiment, of the two inclined portions 28a and 28b, the inclined angle of the inclined portion 28a located on the front side of the container is set to a gentle angle that is slightly horizontal compared to the conventional case, and the inclined angle of the inclined portion 28b located rearward is set. The angle is a gentle angle closer to the horizontal than the inclination of the front inclined portion 28a.

  On the other hand, as shown in FIGS. 9 and 10, the door 26 that is opened and closed when the container 25 is put in and out is fitted with a transparent plate 30 made of acrylic resin or the like fitted into a door frame 29 made of substantially rectangular ABS or the like. A hook-shaped shaft support portion 31 provided on both upper sides of the door frame 29 is pivotally supported on the front end of the shelf plate member 24 so as to be rotatable.

  The door 26 is provided with protruding piece portions 32 on both side portions of the door frame 29 so as to abut against inclined portions 28 a and 28 b provided on the guide piece 27 of the container 25. Projections 33a-1, 33a-2 and 33b are formed on the projecting piece 32 corresponding to the two inclined portions 28a, 28b of the container 25, and the projections 33a-1, 33a-2 are formed. The other protrusion 33b comes into contact with the inclined portion 28b on the rear side of the container, and comes into contact with the inclined portion 28a on the front side of the container.

  In this embodiment, the protrusions 33a-1 and 33a-2 on the side contacting the inclined portion 28a are provided in two, but this may be one.

  Further, as shown in FIG. 10, the container 25 is provided with rails 34 on both side walls thereof, and a partition plate 22a between the first guide member 35 and the water supply tank installation chamber 22 in which the rails 34 are mounted on the walls of the low temperature storage chamber. It is supported by a second guide member 36 provided in the detachable manner.

  A roller 37a for supporting the container 25 is provided at the front end portions of the first and second guide members 35 and 36, and the rear end portion of the rail 34 of the container 25 is made of a resin having good sliding properties such as Duracon. The formed sliding body 37b is incorporated.

  Further, an inclined retracting portion 38 (see FIG. 6) is formed at the rear end portion of the first and second guide members 35 and 36, which becomes lower toward the rear.

  The cold storage chamber 23 has a cold air duct portion 40 formed in a heat insulating material 39 constituting the shelf board member 24, and cold air is supplied from the cold air passage 17 on the back of the refrigerator body 1 through the cold air duct portion 40. Cooling to a predetermined temperature.

  Further, the low temperature storage chamber 23 is provided with a lighting device made of LEDs or the like by forming a recess on the lower surface of the shelf plate member 24, and light from the lighting device in the refrigerator compartment 7 is received by the shelf plate member 24. Even if it does not reach, the inside of the container 25 is irradiated to enhance the visibility of the inside.

  About the refrigerator comprised as mentioned above, the effect is demonstrated next.

First, the cold storage room of the refrigerator is supplied with cold air supplied from the cold air passage 17 of the refrigerator main body 1 through the cold air duct portion 40 provided in the shelf plate member 24, and is stored in the container 25 in the low temperature storage room 23. Ingredients such as meat and fish are cooled and stored at a predetermined temperature. For example, when the low temperature storage chamber is a chilled chamber, it is cooled and stored at about 1 ° C., and when it is a partial chamber, it is stored at a slight freezing temperature of about −3 ° C. And when putting in and out foodstuffs, such as meat and fish, in the said low-temperature storage chamber 23, the container 25 is taken in and out with the handle 25a of the container 25. FIG.

  At this time, the door 26 closing the front opening of the low-temperature storage chamber 23 is opened and closed as the container 25 is put in and out.

  Hereinafter, the opening and closing of the door 26 will be described in detail with reference to FIG.

  First, when taking out the food stored in the cold storage chamber 23 in a cold state, the container 25 is pulled out with the handle 25a. As a result, as shown in FIGS. 11A and 11B, the front side inclined portion 28a provided on the guide piece 27 on the side surface of the container has the lower protrusion portion 33a-1 provided on the protruding piece portion 32 of the door 26. 33a-2 abuts against the protrusion 33a-1, and the inclined portion 28a rotates the door 26 upward from the protrusion 33a-1 via the protrusion 33a-2.

  When the container 25 is pulled out as it is, as shown in FIG. 11 (c), the inclined portion 28b on the rear side of the container is moved to the door 26 almost simultaneously with the contact between the inclined portion 28a and the projection 33a-2. As shown in FIG. 11 (d), the inclined portion 28b rotates the door 26 upward through the protrusion 33b as it is in contact with the upper protrusion 33b provided on the protrusion 32. .

  When the container 25 is further pulled out, the door 26 finally gets over the rear inclined portion 28b provided on the guide piece 27 of the container 25 as shown in FIGS. 11 (e) and 11 (f). It slides to the one part 28d, becomes a fully open state, and is supported in that state.

  Accordingly, in this state, the user can take out the food material inside the container 25 from the front opening portion of the container 25.

  Next, the case where a foodstuff is newly accommodated in the low temperature storage chamber 23 is demonstrated.

  After the container is pulled out as described above, food such as meat and fish is put into the container 25 from the front opening of the container 25, and the container 25 is lightly pushed in by holding the handle 25a. As a result, the protrusion 33b of the door 26 moves from the rear horizontal piece 28d of the container 25 to the inclined portion 28b on the rear side, as shown in FIG. The container 25 is applied to the inclined portion 28b through 33b, and the container 25 is pushed into the cold storage chamber 23 by the component force.

  The container 25 is pushed into the low temperature storage chamber 23 as it is, and the projection 33b of the door 26 is separated from the inclined portion 28b on the rear side of the container 25 as shown in FIG. Almost at the same time, the protruding portion 33a-2 of the protruding portions 33a-1 and 33a-2 on the lower side of the door 26 comes into contact with the inclined portion 28a in front of the container. As a result, the load of the door 26 is applied to the inclined portion 28a in front of the container, and the container 25 is further pushed into the low-temperature storage chamber 23 by the load of the door 26 by the component force. When fully pushed into the cold storage chamber 23, the door 26 closes the front opening of the cold storage chamber 23.

  Here, in the present embodiment, the inclined portion 28 related to the operation force when the container 25 is taken in and out is composed of two inclined portions 28a and 28b having different inclination angles. The power can be light.

That is, if the inclined portion 28a acting at the initial stage of the container withdrawal is made slightly gentler than that of the conventional case, the opening force by rotating the door 26 upward is reduced, and the inclined portion 28a can be pulled out with a light force. Therefore, even if a large force is required momentarily at the start of container withdrawal, the container can be pulled out lighter than before.

  In addition, by making the inclination angle of the inclined portion 28a slightly gentle, it is possible to prevent the container 25 from returning to the low temperature storage chamber 23 by virtue of releasing the hand from the drawn container 25, Usability is improved. That is, when the inclination angle of the inclined portion 28a is steep, the component force in the direction in which the container 25 is pushed in is large, and when the door 26 has a high-class feeling such as a glass door, the weight increases. The force becomes too large, and the container 25 will voluntarily return to the low temperature storage chamber 23, making it difficult for food to be taken in and out. However, according to this embodiment, even if the door 26 has a high-class feeling such as a glass door and its weight increases, such a situation can be prevented.

  Even if the transparent plate 30 of the door 26 that closes the low-temperature storage chamber 23 is made of glass or the like and the weight is increased, the inclination angle of the inclined portion 28a is gentler than before, so that the container 25 is lightened. It can be pulled out. Therefore, the transparent plate 30 of the door 26 can be made of glass or acrylic resin having a thick plate thickness that is easy to increase in weight, and can have a heavy feeling, and can improve the door quality by giving a high-class feeling. .

  Furthermore, if the tilt angle of the tilted portion 28a is made somewhat gentle while having a certain tilt angle, the opening degree of the door 26 is prevented from slowing while reducing the pulling force of the container 25, and the usability is also improved. It can be good. That is, if the inclination angle of the inclined portion 28a is made too gentle, when the container is pulled out, the inclination is loose, so that the opening of the door 26 is delayed and the front opening of the container is not fully opened, and the container 25 is not fully drawn out. It becomes impossible to put in and out ingredients. However, if the inclination angle of the inclined portion 28a is made somewhat gentle while having a certain inclination angle, the door 26 opens reasonably quickly so that food can be taken in and out without having to pull out the container 25 fully. This improves usability.

  Further, since the inclined portion 28b at the rear portion of the container 25 has a certain angle although the inclination angle is somewhat gentler than that of the conventional case, when the container 25 is stored, the component force in the container storing direction due to the door load is reduced. Works. Therefore, the container 25 can be pushed and stored lightly.

  In the present embodiment, since the component force in the container pushing direction caused by the door load is set to be larger than the sliding resistance accompanying the movement of the container 25, the container 25 is automatically pushed only by lightly pushing in and storing. Therefore, it can be pushed into and stored in the low temperature storage chamber 23, and the usability can be improved.

  Further, since the door 26 is heavy using the glass or the thick transparent plate 30 as described above, the component force in the container storage direction caused by the door load becomes larger, and the container 25 is more reliably cooled. It can be automatically pushed into the storage chamber 23 and stored, which is effective in improving the door quality and reducing the operating force.

  In the present embodiment, since the container 25 is supported by the roller 37a and the sliding body 37b, there is little resistance accompanying the movement, coupled with the increased component force due to the door load in the container pushing direction. The automatic push-in and storage of the container 25 can be further ensured.

  The support by the roller 37a and the sliding body 37b can be obtained even if only one of them is supported, and it is only necessary to appropriately select whether or not both are provided.

  Further, as the container 25 is pushed into the low temperature storage chamber 23, the sliding body 37 b provided at the rear end of the rail 34 is drawn into the final position by the inclination of the inclined drawing portion 38. Therefore, the container 25 is reliably moved to the back of the low temperature storage chamber 23 and stored. Further, the container 25 is stopped and held in that position by fitting the sliding body 37b into the inclined retracting portion 38, so that it does not inadvertently move forward, and the reliability becomes high.

  Further, since the projections 33a-1, 33a-2, 33b provided on the door 26 are provided corresponding to the inclined portions 28a, 28b of the container 25, respectively, the optimum for each inclined portion 28a, 28b. An angle can be provided. Accordingly, it is possible to minimize the sliding resistance by suppressing the delicate twisting or the like that tends to occur when one protrusion is brought into contact with the plurality of inclined portions 28a and 28b having different inclination angles. Therefore, the container 25 does not become heavy during loading and unloading, the container 25 can be moved lightly and smoothly over the entire container drawing section, and the usability can be further improved.

  In particular, in this embodiment, since the projections 33a-1 and 33a-2 that are brought into contact with each other at the initial movement of the container are divided into two, the sliding resistance at the initial movement that requires the greatest force is finely adjusted. Therefore, the container 25 can be pulled out with a lighter force.

  As mentioned above, although the refrigerator which concerns on this invention has been demonstrated using the said embodiment, this invention is not limited to this, A various change is possible within the range which achieves the objective of this invention. Needless to say.

  For example, in the above-described embodiment, the storage room provided with the door 26 is described as a low-temperature storage room such as a chilled room or a partial room for supplying cooling air exclusively for the storage room. It may be a storage room that does not have a cold air supply mechanism, for example, a storage room that is provided in the refrigerating room and is maintained at substantially the same temperature as the refrigerating room.

  Moreover, although the inclined part 28 for opening and closing the door 26 is exemplified as having two inclined parts 28a and 28b, it is sufficient that there are at least two or more.

  Further, the angles of the inclined portions 28a and 28b may be arbitrarily set according to the optimum setting of the opening degree speed of the door 26 and the storage capacity of the container 25.

  Moreover, although the case where three protrusion parts 33 were provided in total was illustrated, this may be one although the effect of reducing the sliding resistance between the protrusion part and the inclined part is reduced.

  Further, in this embodiment, the container 25 is provided with the inclined portion 28 and the door 26 is provided with the protruding portion 33. However, the protruding portion 33 may be provided on the container 25 side and the inclined portion 28 may be provided on the door 26. It ’s good.

  Further, the support of the container 25 by the rail 34 and the guides 35 and 36 may be either of the side wall portions of the container 25 or only one of the side wall portions, but is configured to be supported by the both side wall portions. In this case, as illustrated in the present embodiment, even when the low temperature storage chamber 23 is wide enough to have the full width of the refrigerator compartment 7 excluding the water supply tank installation chamber 22, the container 25 can be pulled out and the door 26 can be opened and closed. It is effective because it can be made smooth without twisting from side to side.

Thus, it should be thought that embodiment disclosed this time is an illustration and restrictive at no points. That is, the scope of the present invention is shown not by the above description but by the scope of claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of claims.

  INDUSTRIAL APPLICABILITY The present invention can provide an easy-to-use refrigerator with improved container insertion and removal. Therefore, it can be widely applied to many uses such as commercial refrigerators and showcases as well as home use.
