Description

  The present invention relates to a configuration form of a storage container of a vegetable room in a household refrigerator.

  FIG. 5 is an external perspective view of a conventional refrigerator 1. FIG. 5 shows a configuration of the refrigerator compartment 3, the vegetable compartment 2, the upper freezer compartment 4, and the lower freezer compartment 5 from the top, and shows the appearance when the drawer-type vegetable compartment 2 is opened. It has a rotating door to hold. Cooked foods, semi-cooked foods, seasonings, eggs, bottles, cans, etc. are stored in the refrigerator compartment 3 at about 5-7 ° C, and fresh seafood, meat, fish and livestock paste are stored in the refrigerator compartment 3 Dairy products such as yogurt and cheese are stored in a chilled room at about 1 to 3 ° C. provided in the refrigerator room 3 in an ice greenhouse at about 0 to 1 ° C. provided. On the other hand, ice, ice cream, home-freezing foods, commercial frozen foods, fresh seafood and meats that require long-term storage, etc. are moved to the upper freezer room 4 or lower freezer room 5 at about −18 ° C. The varieties are stored in a vegetable room 2 which is about 2 to 4 ° C. and has been devised to suppress the transpiration of moisture, and management based on temperature is performed.

  FIG. 6 is a sectional view of the vegetable compartment 2 as seen from the side, and FIG. 7 is a sectional view of the vegetable compartment 2 as seen from the front. The vegetable compartment 2 is composed of an upper container 6 and a lower container 7, and a container lid 11 having a moisturizing sheet 9 that retains humidity inside the container and a packing 10 that enhances hermeticity is provided immediately above the upper and lower containers. Has been placed. In the lower container 7, a detachable partition 12 for separating fruits and vegetables such as leaves is provided on the front side, and a standing storage portion A is formed. In the vegetable compartment 2 of such a refrigerator, as shown in FIG. 8, the container structure in which the upper container 6 is fixed to the lower container 7, and the upper container 6 as shown in FIG. There is a container configuration in which the fruits and vegetables in the lower container 7 are taken in and out by sliding to the back side. In this description, the latter more complicated container structure shown in FIG. 6 in which the upper container 6 slides on the lower container 7 to the back and the fruits and vegetables in the lower container 7 are taken in and out will be described.

  The depth of the entire container constituting the vegetable compartment 2 is set based on the height of spinach and the like, which is a typical leafy vegetable stored in the standing storage section A, and a depth of about 260 mm is required. Become. Here, if the thickness of the container is ignored in order to simplify the calculation, the depth of the upper container 6 and the depth of the lower container 7 are values obtained by dividing the depth of the standing storage part A by about 260 mm. Become. Therefore, when the stand storage part A is excluded, two levels of storage depth or height are obtained, and the fruits and vegetables stored in the vegetable compartment 2 are stored in two levels according to size. . For example, if the depth of the upper container 6 is set to about 100 mm, which is generally adopted, the depth of the lower container 7 is necessarily about 160 mm, and a two-stage storage space can be secured. The fruits and vegetables stored in the chamber 2 are classified and stored in the upper container 6, the lower container 7, and the standing storage unit A in terms of both size and usability. The fruits and vegetables stored in the vegetable room 2 vary depending on the season and region, but are generally classified and stored in the upper and lower containers as follows.

  The upper container 6 mainly stores small items that are soft to use, easily damaged skin, fruits and the like, and as tomatoes, tomatoes, cherry tomatoes, okra, shimeji, shiitake mushrooms, sprout, green beans, green beans, nameko , Maitake, peppers, carrots, pumpkins (cuts) and the like are stored, and fruits such as peach, loquat, grapes, strawberries, cherries, apples, plums, lemons and oranges are stored.

  The lower container 7 mainly stores large and hard-skinned items that are hard to be damaged and long items. As vegetables, broccoli, cauliflower, cabbage, Chinese cabbage, lettuce, eggplant, radish, turnip, pumpkin, fruits Contains grapefruits and melons.

  In the vertical storage section A, mainly vegetables such as leaves and long things that fit within a depth of about 260 mm are stored, such as spinach, chingensai, silkworm, honeybee, asparagus, cucumber, and the like.

  Regarding the vegetable container, there is Japanese Patent Application No. 7-324197 as a prior application.

  When the vegetable room 2 shown in FIG. 6 and FIG. 7 is observed from the housewife's consciousness of storage and the actual condition of usability, the upper container 6 mainly stores small items that are easy to use, items that are soft and easily damaged, fruits and the like. While it wants to do it, it is a storage form in which fragile items and large items with relatively hard skin are mixed. In addition, the depth of the upper container 6 is about 100 mm, while the height of relatively large citrus fruits represented by grapefruit is around 110 mm, so the depth is slightly insufficient and the lower container 7 is moved to the lower container 7. Is forced to store.

  The same applies to the lower container 7, which mainly intends to store large items and epidermis that are relatively hard and hard to be damaged, and long items, but is sensitive to perishable items such as cauliflower, broccoli, lettuce, etc. The storage form is a mixture of hard and big items. As the storage container of the vegetable compartment 2, except for the standing storage part A, it has a two-stage storage part of an upper container 6 and a lower container 7, but when looking at the current storage situation, It is a storage form that is mixed with the lower container, such as when searching for vegetables to use, when taking out the back items, or when securing a place to store newly, the overlapping fruits and vegetables adjacent to each other collide, Not a few scratches and deterioration occur.

  In addition, due to the difficulty in finding stored items due to mixing, it has also occurred that the product is purchased again despite the fact that the fruits and vegetables are stored. The depth of the lower container 7 is set to about 160 mm as a height satisfying storage of 2L size or less of the agricultural cooperative shipping standard sold in general supermarkets etc., taking a large cabbage as an example. In addition, large items exceeding the 2L size of the agricultural cooperative shipping standard are often mixed and distributed, and off-market distribution tends to increase due to the expansion of courier services and direct delivery from production areas. There is a need for extra space, and it is desired to further increase the size of the lower container 7 for storing large items.

  The present invention intends to secure a storage portion with high storage performance. It is another object of the present invention to provide a refrigerator capable of improving the ease of sorting and organizing, suppressing scratches caused by collisions caused by mixing, and maintaining the freshness of stored fruits and vegetables.

The present invention is a refrigerator equipped with a drawer-type vegetable compartment,
The vegetable compartment is composed of an upper container and a lower container, and is opened and closed by pulling out the drawer-type vegetable compartment door, and the upper and lower containers together with the vegetable compartment door by pulling out the vegetable compartment door. And withdrawing together,
The upper container closes a part of the opening of the lower container, and a storage space at the back of the lower container is formed by a side surface and a back surface of the lower container, and a bottom surface of the upper container, and the lower container The lower container is configured to be slidable to the back side so as to be provided with a standing storage part whose upper surface is open on the front side, and the bottom part has left and right storage part depths.
The vegetable compartment includes: the stowage storage part; the storage part on the shallow side of the upper container; the storage part on the deep side of the upper container; and the upper container below the storage part on the shallow side of the upper container. There are five storage locations including a storage portion between the bottom surface and a storage portion between the storage portion on the deep side of the upper container and the bottom surface of the upper container on the lower side, and these five storage portions The storage depth is different from each other.

  Further, the opening of the lower container is partially closed by the upper container, and the upper container is divided into a storage part on the shallow side of the upper container and a storage part on the deep side of the upper container by the step part. It is characterized by that.

  Further, the storage depth of the storage portion between the storage portion on the deep side of the upper container and the bottom surface of the upper container on the deep side is deeper than the storage depth of the storage portion on the deep side of the upper container. It is what.

  In addition, a container lid is disposed immediately above the main body side of the upper and lower containers.

  Further, of the five storage units, the storage unit on the shallow side of the upper container, the storage unit on the deep side of the upper container, the bottom surface of the upper container on the lower side of the storage unit on the deep side of the upper container, The four storage parts of the storage part between the storage part between and the storage part between the lower part of the storage part on the shallow side of the upper container and the bottom surface of the upper container in this order, the storage part depth increases in order at substantially equal pitches It is set as follows.

  According to the present invention, it is possible to provide a refrigerator having a vegetable room with high storage capacity. Further, since the back portion of the lower container is almost closed by the upper container, the high humidity state in the lower container is maintained. It is possible to maintain the freshness of the stored fruits and vegetables.

  When examining the container form of the vegetable room 2, as a grasp of the actual situation, we conducted a storage situation survey of the types of fruits and vegetables stored in the vegetable room 2 of a general household refrigerator. As shown in the table, many types of storage are stored, and the storage of fruits and vegetables ranked higher was considered as the basis for consideration.

  Based on the results of this investigation, when the shipping standards of agricultural cooperatives ranked higher were examined, it was found that the values were as shown in FIG. In addition, in order to grasp the actual size of fruits and vegetables obtained by consumers in general households, a purchase survey of various fruits and vegetables sold in major supermarkets was conducted, and survey data as shown in FIG. 11 was obtained as an example.

  When assuming the size of the main fruits and vegetables stored in the vegetable room 2 by general consumers, the survey data of FIGS. I decided to take this into account. As for the ease of taking in and out of fruits and vegetables, from the survey results of the housewife's usability and storage consciousness in the vegetable room 2, leaves such as spinach and slender items such as cucumber and asparagus are placed in the standing storage section A on the front side. Strawberries, grapes, peaches, loquats, etc. that are soft and easily damaged by scratches, fruits in plastic packs, hard-fruited grapefruits, oranges, lemons, etc. are placed in the upper container 6 and cabbage, Chinese cabbage, lettuce, etc. Has been confirmed to be stored in the lower container 7.

  Therefore, when examining the storage container form of the vegetable compartment 2, it is naturally important to consider the dimensions and usability of the fruits and vegetables. The depth of the whole container which comprises the vegetable compartment 2 is set on the basis of the height of the spinach which is a typical leafy vegetable stored in the standing storage part A, and the depth of the upper container 6 and the lower container 7 Is a value obtained by internally dividing the depth of the standing storage portion A of about 260 mm by the depth of the upper container 6. That is, the bottom part of the upper container 6 is configured so that the storage part depth has two levels on the left and right sides, so that the storage part height of the lower container 7 disposed on the lower side is handled in two stages. is there.

  Specifically, by storing the upper container 6 having a bottom shape as shown in the sectional view of the vegetable compartment seen from the side of FIG. 2 and the sectional view of the vegetable container seen from the front of FIG. Without changing the dimension of about 260 mm which is the height of the entire portion, it is intended to secure four stages of storage portions having different depths or heights of the B to E portions as storage portions with high storage performance. In addition, the upper and lower containers, which were previously set as two stages, are changed to a four-stage storage section, which improves the ease of sorting and organizing fruits and vegetables, and damage caused by collisions caused by mixing. It is also possible to suppress sticking.

  In addition, an upper container 6 is provided so as to close a part of the opening of the lower container 7, and the upper container 6 is structured to be slidable to the back side with the lower container 7 as a base. When the lower container 7 and the lower container 7 are combined, the back part of the lower container 7 is almost closed by the upper container 6 so that the high humidity state in the lower container 7 is maintained.

  As an effect, by making the storage structure in which a part of the opening of the lower container 7 is closed by the upper container 6, the standing storage part A can be set on the front side, and the upper container 6 is slid to the back side. Therefore, the fruits and vegetables in the lower container 7 are easy to see and put out. Further, by adopting a structure in which the back portion of the lower container 7 is substantially closed by the upper container 6, the high humidity state in the lower container 7 is maintained, and the freshness of the stored fruits and vegetables can be maintained.

  Further, in constructing the bottom surface of the upper container 6 so that the housing part depth is two steps on the left and right, the dividing line is made substantially at the center of the container width, and the step part 15 serving as the dividing line is formed. By providing the extension 16 with the rising prevention 16, the fruits and vegetables of the storage unit B and the storage unit C can be classified, and even spherical or cylindrical ones can be dropped from the storage unit B to the storage unit C. It makes it possible to organize and store.

  Moreover, as shown in the external perspective view of FIG. 1, in the refrigerator 1 in which the refrigerator compartment 3 and the like excluding the drawer-type vegetable compartment door 8 are configured as a revolving door by the hinge mechanism 13, the storage portion depth is two stages. The upper container 6 configured to be shallower is positioned on the side of the hinge mechanism 13 of the door of the refrigerator compartment 3 and the like, and the upper container 6 side has a height dimension higher than that of the lower container 7. By storing a small storage item, it is possible to minimize the impact associated with the opening and closing of the refrigerator compartment 3 and the like, and to suppress mechanical stress due to the impact on the stored fruits and vegetables.

  Further, the depth of the lower container 7 is set to 260 ± 10 mm in accordance with the height of leaves such as spinach that needs to be stowed, and the upper stage is closed so that a part of the opening of the lower container 7 is closed. By providing the container 6 in the lower container 7 and forming the depth dimension of the upper container 6 to be smaller than 1/2 of 260 ± 10 mm, it becomes possible to classify and accommodate the housewife's convenience and storage needs. It is a thing.

  Further, by providing the upper container 6 in the lower container 7 so as to close the rear of the opening of the lower container 7, and providing the cold air outlet 16 to the vegetable compartment 3 in the vicinity of the upper container 6, The inside of the upper container 6 can be set to a temperature lower than that of the lower container 7, and the freshness of fruits and the like can be further maintained.

In the vegetable room 3 having a storage structure composed of two upper and lower containers, a step of 30 ± 10 mm is provided on the left and right of the bottom surface of the upper container 6, and the depth on the shallow side of the upper container 6 is 85 ± 10 mm. The depth of the deep side of 6 is 115 ± 10 mm, the height of the shallow side of the lower container 7 is 145 ± 10 mm, and the height of the deep side of the lower container 7 is 175 ± 10 mm. 260 ±
By setting it to 10 mm, it is possible to secure a storage space in four stages according to the size of the stored fruits and vegetables without increasing the height of the upper and lower two-stage container combination.

  Furthermore, if the storage portion A is provided on the front side of the lower container 7, a storage space of five levels can be secured.

  FIG. 1 is an external perspective view of a refrigerator 1 according to an embodiment of the present invention, and shows an external appearance when a drawer-type vegetable room 2 is opened. 2 is a cross-sectional view of the vegetable compartment 2 portion viewed from the side, and FIG. 3 is a cross-sectional view of the vegetable compartment 2 portion viewed from the front.

  As shown in FIGS. 1, 2, and 3, the refrigerator compartment 3 is formed in the upper part, and the storage compartments of the refrigerator 1 are constituted by the upper freezer room 4 and the lower freezer room 5 in the lower part. The vegetable compartment 2 is composed of an upper container 6 and a lower container 7, and the upper and lower containers are pulled out together by the drawer-type vegetable compartment door 8 of the vegetable compartment 2. Further, as shown in FIG. 2, a container lid 11 having a moisture retaining sheet 9 that retains the humidity inside the container and a packing 10 that enhances hermeticity is disposed immediately above the main body side of the upper and lower containers.

On the other hand, in the lower container 7, a detachable partition 12 for separating fruits and vegetables such as leaves is provided on the front side, and a standing storage portion A is formed. In the vegetable compartment 2 of such a refrigerator, as shown in FIG. 4, the upper container 6 is fixed to the lower container 7, and the upper container 6 as shown in FIG. Although there is a container configuration in which the fruits and vegetables in the lower container 7 are taken in and out by sliding to the back side, according to the present invention, it is possible to carry out either container configuration, but in this description, it is more complicated. The latter case shown in FIG. 2 will be described with the container configuration in which the upper container 6 slides back on the lower container 7 and the fruits and vegetables in the lower container 7 are taken in and out.

When setting the depth of the entire container constituting the vegetable room 2, the height of spinach, which is a typical leafy vegetable stored in the standing storage section A as in the conventional case, is set to about 260.
It is necessary to secure a depth of mm. Here, in order to simplify the calculation as in the conventional example, the thickness of each container is ignored and the description will be given with reference to FIG.

  The depth of the upper container 6 and the depth of the lower container 7 are values obtained by internally dividing about 260 mm, which is the depth of the standing storage portion A. When setting the depth of the upper container 6 to be divided, it is necessary to consider the housewife's storage consciousness and ease of use. 115 mm can be set, and the depth of the lower container 7 at the lower part is necessarily about 145 mm.

  In addition, about 175 mm can be set by adding about 15 mm of dispersion due to off-market distribution to about 160 mm which is the height converted from the 2L size cabbage which is a large item stored in the lower container 7. The depth of the upper container 6 is inevitably about 85 mm, and the four steps can be set at equal intervals of 30 mm.

  When confirming the fruits and vegetables that can be stored in the upper and lower containers, the shallow container B of the upper container 6 has a pack container such as grapes, cherries, strawberries, and small tomatoes, a tray container such as shiitake mushrooms, green beans, etc. Can store bags, peaches, oranges, lemons, tomatoes, etc.

  In the deep storage section C of the upper container 6, not only large citrus fruits such as grapefruit, but also plums and loquats contained in a large pack container are stored. Of course, it is possible to store fruits and vegetables that are put in the shallow storage section B of the upper container 6.

  On the other hand, the shallow storage portion D of the lower container 7 can store eggplant, carrot, lettuce, cauliflower, broccoli, and the like, and the deep storage portion E can store large vegetables such as Chinese cabbage, cabbage, and pumpkin. In addition, the lower container 7 is also provided with a standing storage portion A for a leaf or a long object that can be accommodated at a depth of about 260 mm.

Thus, by providing a step of about 30 mm on the left and right of the bottom surface of the upper container 6, the depth of the shallow storage part B of the upper container 6 is about 85 mm, and the depth of the deep storage part C of the upper container 6 is about 115 mm, The depth of the shallow storage part D of the lower container 7 is about 145 mm, and the depth of the deep storage part E of the lower container 7 is about 175.
By setting it to mm, according to the size of the fruits and vegetables to be stored in the upper and lower containers, four stages are stored in the upper and lower containers, and five stages are stored when the standing storage part A is included.

  Therefore, it is possible to sufficiently cope with larger vegetables without changing the overall depth of the vegetable compartment 2, and it is possible to provide a vegetable compartment 2 that is easy to put in and out with little overlap in each storage section.

  According to the above configuration, the bottom of the upper container 6 of the vegetable compartment 2 is configured to have two levels of storage depth on the left and right, so that the storage height of the lower container 7 disposed on the lower side is also two levels. As a result, it is possible to store larger items even at the same container height as before, and it is now possible to store classified items that meet the needs of housewives.

  Therefore, it was possible to find a small vegetable that was difficult to find because it was hidden behind a large object, and a form that was easy to put in and out was obtained. Furthermore, since high storage capacity is obtained, the stored fruits and vegetables in the upper and lower containers can be confirmed at a glance, double purchases can be prevented, and deterioration of freshness due to damage to fruits and vegetables at the time of loading and unloading can be suppressed.
