Further, a third dent portion 124 is formed in a corner portion at the rear of the bottom surface of the heat insulating box 101, and a defrost water evaporator 125 is installed.

  The dent part 121, the second dent part 122, the third dent part 124, and the evaporator 120 are arranged in a substantially straight line in the vertical direction on the back surface of the refrigerator body. Among these, since the control board 123 accommodated in the 2nd dent part 122 needs only a comparatively thin space, since it is also possible to obtain | require suitable installation space in another site | part, at least the dent part 121, the 3rd If the recessed portion 124 and the evaporator 120 are arranged on the back surface of the refrigerator main body in a substantially straight line in the vertical direction, the space including the structures and parts that do not contribute to the space in the cabinet is arranged in a fixed manner. Can be organized. At this time, the third dent portion 124 is located behind the front surface of the heat insulating material that insulates the front portion of the evaporator 120 when viewed from above, and does not bite into the indoor side of the freezer compartment 106. It is formed as a long space in a wide width direction.

  Only one evaporator 120 is disposed across the rear of the vegetable compartment 105 and the freezer compartment 106, and heat exchange is promoted by a cooling fan (not shown) provided in the vicinity of the upper portion to force forced convection into each room. Cooling.

  The condenser (not shown) includes a natural air-cooling type that is thermally conductively attached to the inside of the outer box 126 with aluminum foil or the like, and an outer box (a partition wall portion between the chambers) around the front opening of each chamber. The main condenser is high-pressure piping that is provided on the back side to prevent condensation.

  In other words, by utilizing the necessary space formed in advance for the configuration of other equipment, parts, etc., the space inside the refrigerator main body is not substantially reduced (the space inside the warehouse is substantially reduced). Condensers installed in a form that does not have a significant influence on the above may be provided in an auxiliary manner. For example, a condenser that is installed in the recess 121 and promotes heat dissipation of the high-temperature refrigerant discharged from the compressor 119 or a third recess 124 to promote evaporation of defrosted water from the evaporator 120. For example, a condensation pipe serving as a heating source for the evaporation promoting device 125.

  A first partition wall 127 is provided between the refrigerator compartment 102 and the ice making chamber 103 and the specific cooling chamber 104, and a second partition wall 128 is provided between the ice making chamber 103 and the specific cooling chamber 104 and the vegetable compartment 105. A rigid partition foam 129 is provided between the freezer compartment 106 and the third partition wall 129, and the first, second and third partition walls 127, 128 and 129 are filled and foamed in the heat insulating box 101. The foam heat insulating material 130 such as is integrally foamed at the same time. In addition, it is not always necessary to spread and fill the foam insulating material 130 throughout the first, second, and third partition walls 127, 128, and 129, and another heat insulating material is partially used as necessary. (Such as polystyrene foam or vacuum heat insulating material) and other structures may be included. In addition, it is not always essential to foam together with the heat insulating box 101, and the first, second, and third partition walls 127, 128, and 129 are related to the manufacturing process, assembling workability, and the like. And may be configured to be assembled as a separate body after heat insulation foaming.

  In addition, a vacuum heat insulating material is combined with the foam heat insulating material 130 in the heat insulating walls on both sides and the back of the ice making chamber 103, the specific cooling chamber 104, the vegetable chamber 105, and the freezing chamber 106 below the first partition wall 127. 131 is disposed.

  The vacuum heat insulating material 131 is adhered and adhered to the outer box 126 side using an adhesive member (not shown). Further, the vacuum heat insulating material 131 is required to be thin and flat in order to be disposed within the thickness of the heat insulating box 101. Further, an adhesive member such as hot melt is applied on the entire surface of the vacuum heat insulating material 131 so that air does not enter the bonded portion. The vacuum heat insulating material 131 is foamed integrally with the foam heat insulating material 130 to form the heat insulating box 101, and has a heat insulating performance 5 to 20 times that of the foam heat insulating material 130.

  In addition, you may insert in the vacuum heat insulating material 131 and the 1st, 2nd, 3rd partition wall 127,128,129 as needed.

The vacuum heat insulating material 131 is made of a material having a large specific gravity such as glass fiber, pearlite, or silica as an inorganic material. The density of the foam heat insulating material 130 (rigid foamed urethane) is 20 to 50 kg / m ³ , while the density of the vacuum heat insulating material 131 is 200 to 250 kg / m ³ , which can be at least four times higher.

  About the refrigerator comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

  First, the operation of the refrigeration cycle will be described.

  The refrigeration cycle is operated by a signal from the control board 123 according to the set temperature in the refrigerator, and the cooling operation is performed. The high-temperature and high-pressure refrigerant discharged by the operation of the compressor 119 dissipates heat in the condenser to be condensed and liquefied, and is depressurized in the capillary tube to become a low-temperature and low-pressure liquid refrigerant and reaches the evaporator 120.

  By the operation of a cooling fan (not shown), heat is exchanged with the air in the warehouse, and the refrigerant in the evaporator 120 is evaporated. Each room is cooled by distributing low-temperature cold air with a damper (not shown) or the like. The refrigerant that has left the evaporator 120 is sucked into the compressor 119. Thus, the inside of the cabinet is cooled by repeating the cycle operation.

  Next, the configuration and arrangement of the storage room will be described from the viewpoint of usability.

  In the refrigerator compartment 102, the compressor 119 etc. accommodated in the machine room 119 are used and installed in the recess 121 at the rear of the top surface of the heat-insulating box 101 which is not convenient. Accordingly, the movement of the machine room 119, which is conventionally behind the lower part of the heat insulation box, that is, behind the freezer compartment 106, lowers the indoor height of the freezer compartment 106 by the volume of the machine room 119 while maintaining the capacity. be able to. Along with this, the ice making room 103, the specific cooling room 104, and the vegetable room 105 arranged in the upper part slide to lower the height from the refrigerator installation surface. Accordingly, the height from the refrigerator installation surface on the bottom surface of the refrigerator compartment 102 is also lowered.

  Further, if all of the first partition wall 127, the second partition wall 128, and the third partition wall 129 are filled with foamed heat insulating material such as hard foamed urethane, the heat insulating properties of all the partition walls are improved. As a result, the first partition wall 127, the second partition wall 128, and the third partition wall 129 can be thinned, and the volume created thereby is smoothed to create the ice making chamber 103 and the specific cooling chamber 104. , The height from the refrigerator installation surface of the vegetable room 105 and the freezing room 106 is lowered downward, and accordingly, the height from the refrigerator installation surface on the bottom surface of the refrigerator compartment 102 is also lowered, The room height increases and the capacity increases.

  Further, by providing a vacuum heat insulating material 131 in at least the ice making chamber 103 and the specific cooling chamber 104, the vegetable chamber 105, and the heat insulating walls on the side and back of the freezing chamber 106, the ice making chamber 103, the specific cooling chamber 104, and the vegetable chamber. 105, since the heat insulating properties of the heat insulating walls on the side surface and the back surface of the freezer compartment 106 are further enhanced, the composite foam heat insulating material 130 can be thinned to realize a thin wall, and the volume created thereby can be reduced. Then, the height of the ice making room 103, the specific cooling room 104, the vegetable room 105, and the freezing room 106 from the refrigerator installation surface is lowered, and accordingly, from the refrigerator installation surface on the bottom surface of the refrigerator room 102, Is also lowered, the indoor height of the refrigerator compartment 102 is expanded, and the capacity is increased.

Furthermore, by using a material having a large specific gravity (200 to 250 kg / m ³ for urethane foam 20 to 50 kg / m ³ ) such as glass fiber, pearlite, or silica as an inorganic material for the core material of the vacuum heat insulating material 131, Compared with the upper part of the refrigerator, the weight of the lower part can be increased to lower the center of gravity of the refrigerator, improving the stability against falling and improving the safety against earthquakes. In addition, in the case of a refrigerator in which the compressor 119 is disposed at the top, such contribution to stability draws out a function that has a potential effect other than the main function and effect of the vacuum heat insulating material 131, and a new It can produce an effect and can be a reasonable form of high utility value.

  Also, the condenser of the refrigeration cycle conducts heat to the outer box of the refrigerator body, except for the condenser that is housed in the installation site that does not reduce the space inside the cabinet just for its own installation. Conventionally, in order to install a condenser, the effective space is not reduced by biting into the inside of the cabinet.

  For example, even if a certain space is formed outside the freezer compartment 106 at the bottom or rear side of the refrigerator, and the storage space for the condenser is not secured in a form that affects the effective space inside the refrigerator, By utilizing the box 126 as a heat radiating plate in heat conduction, the condensing capacity can be secured. As a result, the space required for accommodating the condenser is transferred to the volume inside the warehouse, and the volume created thereby. The ice making room 103, the specific cooling room 104, the vegetable room 105, and the freezer room 106 are lowered downward from the refrigerator installation surface, and the refrigerator on the bottom surface of the refrigerator room 102 is accordingly lowered. The height from the installation surface is also lowered, and the indoor height of the refrigerator compartment 102 is expanded, increasing the capacity.

  In this way, by using the various means described above, a volume that can be used as an effective space in the warehouse is newly created by converting or reducing the main ineffective space factors that previously pressed the effective space inside the warehouse. On the other hand, the total of the created volumes is distributed to lower the height from the refrigerator installation surface while appropriately maintaining the internal volumes of the ice making room 103, the specific cooling room 104, the vegetable room 105, and the freezing room 106. Thus, the bottom surface of the refrigerator compartment 102 is also lowered, and the height of the lowermost storage space 113e from the refrigerator installation surface is also lowered.

  That is, as a result, the storage space 113e at the lowest level in the refrigeration room, the ice making chamber 103, and the specific cooling for storing articles (eg eggs, small items, ice, daily foods, water tanks for ice making) that are frequently used daily. The height of the storage space in the chamber 104 from the refrigerator installation surface is considerably lowered while maintaining the volume.

  On the other hand, an ergonomic aspect that makes it difficult for the arm muscles to be burdened when a user with a standard height (157 cm) of a Japanese adult female is standing and performing the operation of loading and unloading these frequently used items. Is the height range from the refrigerator installation surface with the user standing 20cm away from the refrigerator (Figure Ernomics P105 Figure 2.7.12, edited by the Japanese Standards Association, published in 1990) The dimension is within the range of 75 cm or more and 115 cm or less, and by putting a storage space frequently used in this range on a daily basis, the user can stand and put in and out these frequently used items. When doing this, you can put in and out the article in a natural posture as much as possible without putting a burden on the muscles of the arm. By consolidating the storage space of the high use frequency goods, it can greatly improve the ease of use.

  Moreover, the height dimension from the refrigerator installation surface of the bottom of the lower indoor opening of the ice making chamber 103 or the specific cooling chamber 104 is H1, and the shelf 102a that divides the refrigerator compartment 102 into a plurality of storage spaces in the vertical direction Among them, when the height dimension from the refrigerator installation surface on the bottom surface of the bottom shelf is H2, H1 ≧ 75 cm and H2 ≦ 115 cm are set, and the opening height dimension of each of the storage spaces frequently used is regulated within this range. Therefore, when taking out and putting in frequently used items stored in these storage spaces, the user can stand in a standing posture and take out and put in the items with a natural posture as much as possible. The storage space for frequently used items is concentrated in a height zone that is ergonomically less burdensome for the user. The ease of use can be greatly improved.

  In addition to this, when the height dimension of the bottom surface of the refrigerator compartment 102 from the refrigerator installation surface is 97 cm or less, when articles are taken in and out of the ice making chamber 103 and the specific cooling chamber 104 below the refrigerator compartment 102. Since the height of the elbow of a Japanese adult female (157 cm) is 97 centimeters (illustration ergonomics, published by the Japanese Standards Association, published in 1990), the arm height can be increased without raising the elbow. The burden is lighter, and you can easily take out ice and put in and out the stored items while standing.

  In addition, after satisfying this easy-to-use height range, a part of the created volume can be added to the vegetable room volume or freezer room volume and distributed. It can be set as the combination which satisfies uses, such as standing storage of large-sized drink containers.

  In the present embodiment, the layout of each room described above, that is, the layout of the refrigerator room, ice making room and specific cooling room, vegetable room, and freezer room from the top, is ergonomically placed in a height zone with a low burden on the user. In order to smoothly fit the storage space that is frequently used, that is, the lowermost storage space 113e in the refrigeration chamber, the ice making chamber 103, and the specific cooling chamber 104, a means by reducing some invalid volume or changing the arrangement is used. Although it was used, it is invalid in the idea of the present invention when it is not necessary to tie it up with an increase in volume, or when it is acceptable in terms of balance and usability even if the volume of a specific room is intentionally reduced Adjust the volume and height of each room without using the means of reducing the volume or changing the layout, and refrigerate the storage height zone with less burden on the user. Lowermost storage space 113e of the inner, ice making room 103, it is also effective to keep the specific cooling chamber 104.

  In addition, since the freezer compartment 106 is arranged below the vegetable compartment 105, the vegetable compartment 105, which is frequently used for health in recent years and has many large items such as Chinese cabbage, cabbage, pumpkin, radish, watermelon, etc. The arrangement close to the above-described easy-to-use height zone allows the user to put in and out the article without bending his / her waist greatly, thus reducing the burden on the waist and the like, and is convenient.

  Even if the freezer compartment 106 is further below the vegetable compartment 105, the frequently used ice storage portion is separated and arranged in a height zone that is easy to use as the ice making room 103, so the burden is reduced.

  Further, the door of the refrigerator compartment 102 is provided with a rotary single door or a double door 108, and is housed in the ice making chamber 103, the specific cooling compartment 104, the vegetable compartment 105, and the freezer compartment 106 other than the refrigerator compartment 102. Because it is equipped with a drawer-type door that supports the container, even in the height range where it is difficult to put a burden on the arm, the refrigerator compartment zone at the top is a natural posture with the arms extended as the rotary doors 107 and 108 The ice making chamber 103 and the specific cooling chamber 104 at the bottom can be used as pull-out doors 109, 110, 111, 112 with the upper surface open, and the elbow is raised up while looking out the entire container. You can put your hand in and out of the storage container with a natural arm condition without feeling the burden on the arm.

  By providing the vegetable compartment 105 and the freezer compartment 106 also with a drawer-type door, a certain ease of use can be enjoyed in the same manner without taking an unnatural posture to fall down and look into.

  In particular, when the double door 108 is provided on the door of the refrigerator compartment 102, there are the following advantages. That is, the upper limit of the height dimension from the refrigerator installation surface on the upper surface in the lowermost storage space 113e of the refrigerator compartment is within 115 cm or less, or the height dimension from the refrigerator installation surface on the bottom surface in the refrigerator compartment 102 is 97 cm. By making the following, the size of the refrigerator compartment in the height direction can be made larger than before, but in association with this, the refrigerator compartment door is also enlarged, and usually has a storage space on the back side of the door. The burden on the user who opens and closes the door tends to increase. On the other hand, by using the double-folded double door 108 as the rotary door, the door opening / closing burden is reduced to almost half, and the front space required for opening the door is small and the capacity is increased. The space occupied by the refrigerator can be pushed compactly.

  In addition, by storing the storage pocket 108a at the bottom of the door of the refrigerator compartment in a height dimension of 115 cm or less from the refrigerator installation surface, articles (beverages and various seasonings that are very frequently used) stored in the back space of the door. In the same way, when a user performs a taking-out operation in a standing posture, the user can put in and out an article in a natural posture as much as possible, which does not place a burden on the arm muscles. Convenience can be greatly improved by consolidating storage spaces for articles that are frequently used on a daily basis in a height zone that is less burdensome for the user.

  In addition, the height of the vegetable compartment 105 is that a beverage container having a height of 32 cm, such as a 2-liter beverage that is frequently used in recent years, is placed in an upright position. These heavy containers can be stowed and stored in a vegetable room, and can be put in and out with an easy standing without bending over and without raising the elbows and placing a burden on the arms.

  Further, since the water storage tank 116 for ice making is provided in the lowermost storage space 113e of the refrigerator compartment, the water tank 116, which is relatively heavy by putting water into it, has a height that does not burden the arm. In addition, the ice making chamber 103 is directly adjacent to the ice making water, so that the water supply path for ice making can be shortened and simplified.

  Similarly, since the container 115 for storing eggs is provided in the lowermost storage space 113e, eggs that are frequently used and require careful handling such as cracking can be easily put in and out at a height that is easy to handle. be able to.

  In addition, if the specific cooling chamber 104 is a temperature switching chamber in which the temperature can be switched between a freezing temperature zone, a refrigeration temperature zone, and an intermediate temperature zone between freezing and refrigeration, there are various types of zones in a standing posture that does not burden the arm. A combination including a storage space in a temperature zone is possible. For example, the temperature switching chamber 104 is made to be a chilled (for example, −1 to 1 ° C.) or partial freezing (for example, −3 ° C. to −3 ° C.) 1 ° C), the storage space 113e at the bottom of the refrigerator compartment and the ice making chamber 103 can be combined with storage spaces in all temperature zones in this convenient zone. Foods that are frequently used on a daily basis can be used in an easy-to-use manner with a high storage quality that is appropriate for the belt.

  For example, when the temperature switching chamber 104 is set to a freezing temperature zone, three freezing chambers are formed together with the ice making chamber 103 and the lower freezing chamber 106, and ice is stored in the ice making chamber 103 and stocked in the lower freezing chamber 106. Frozen foods that are frequently used, such as frozen foods and ice cream for side dishes for lunch boxes, if you store frozen foods for long-term storage of molds and store flow-type frozen foods for short-term storage in the temperature switching chamber 104 Is extremely easy to use.

  Further, the evaporator 120 of the refrigeration cycle is configured such that only one evaporator is disposed across the rear of at least two chambers other than the refrigerator compartment 102, so that the entire storage chamber in the refrigerator main body is one evaporator. Since it is cooled by 120, a plurality of evaporators are not required and the installation space can be reduced, and the single evaporator 120 is not pushed into the back of one chamber other than the refrigerating chamber 102, but straddles the back of at least two chambers. In order to arrange, the height dimension of the evaporator 120 can be expanded and, conversely, the depth dimension can be decreased to provide the same cooling capacity.

  According to this, the influence of the installation space of the evaporator 120 on the inner side of the evaporator 120 affects only one room, and the room height has to be increased in order to secure the minimum necessary internal volume of the room. Cases, and conversely, the room where the evaporator 120 is not installed, for example, because of the restriction of storing articles with height restrictions such as PET bottles, although the room height can be lowered in terms of internal volume. Inconveniences that limit the degree of freedom in design, such as cases where the height cannot be lowered, can be avoided.

  Therefore, the height dimension from the refrigerator installation surface of the storage space in the lowermost storage space 113e and the ice making chamber 103 and the specific cooling chamber 104 in the refrigerator compartment is set to 75 cm or more and 115 cm by various means as described above. When the height dimension from the refrigerator installation surface on the bottom surface of the refrigeration room is within 97 cm or less, the room structure can be made flexible.

  For example, the resin caps at the upper ends of the drawer door 109 of the ice making chamber and the drawer door 110 of the specific cooling chamber are shaped so as to be cut obliquely downward from the rear toward the front. Handles 117 and 118 are formed to hold the hand when it is pulled out. The handle is open at the top and has a concave pocket at the bottom. The door can be opened and closed by placing your fingers with the palm facing down. Therefore, when the door of the ice making chamber 103 or the specific cooling chamber 104 is opened, the handle portions of the handles 117 and 118 are easy to see from above for the user standing in front of the refrigerator, and the drawer operation can be carried out with ease. It can be opened and closed quickly and easily.

  In the present embodiment, the volume created by the various means described above is allocated to the refrigerator compartment 102 to achieve a large capacity of the refrigerator compartment 102, and set to a height dimension range that is easy to use ergonomically. In the central zone, the storage space 113e at the bottom of the refrigerator compartment, the ice making compartment 103, and the specific cooling compartment 104 are integrated to pursue both ease of use and large capacity, but the created volume is reduced to the refrigerator compartment 102. If it is provided as a low-height type refrigerator that maintains the volume of the refrigerator compartment 102 before creation and lowers the overall height of the refrigerator, the difficult space in the upper part of the refrigerator compartment is lowered, making it easier to use. Although the capacity does not increase, the refrigerator can be an easy-to-use refrigerator that fits in the entire refrigerator.

  In this embodiment, the freezer compartment 106 is disposed below the vegetable compartment 105. Conversely, when the vegetable compartment 105 is disposed below the freezer compartment 106, the freezer compartment 106 and the ice making chamber 103 serving as a freezing zone are provided. It is adjacent to the top and bottom of an easy-to-use height zone, and a layout that is highly convenient for bulk-buying double-income households that make heavy use of frozen foods and households that need to make lunch boxes further reduces the burden. There is an advantage that it can be used easily.

  In addition, since the freezer compartment 106 and the ice making chamber 103 in the freezing zone are adjacent to each other, it is easy to rationally organize the configuration in terms of the cooling function, and communication is performed without providing a partition wall between the ice making chamber 103 and the freezer compartment 106. It is also possible to simplify the cooling air passage configuration.

  Furthermore, if the freezer compartment 106 is arranged on the side of the vegetable compartment 105, a section in which the dimensions in the height direction can be sufficiently obtained while partially enjoying the good layout arrangement of the vegetable compartment 105 and the freezer compartment 106 described above. Since it becomes a structure, a long vegetable and frozen food can be stored in the vertical direction, and the variation of stored goods can also be expanded.

  The refrigerator of the present invention is easy to use because the user places the storage space for frequently used items in a zone where the user is less burdensome on the muscles and can work easily in a standing position. Therefore, the present invention can be applied not only to household refrigerators but also to commercial refrigerators such as large refrigerators, freezers and showcases.

In order to solve the above-described conventional problems, the refrigerator of the present invention is set to a refrigerator body formed of heat insulating walls, a refrigerator room provided at the upper part of the refrigerator body, and a freezing temperature zone provided at the lower part of the refrigerator room. and ice making room to be, the specific cooling chamber is set to at least a refrigeration temperature zone juxtaposed to the ice making compartment, by arranging the freezer compartment and a vegetable compartment below the said ice-making chamber and the specific cooling chambers arranged in parallel The freezing room, the specific cooling room, and the ice making room are provided with three freezing storage rooms, and the lowermost storage space among a plurality of storage spaces partitioned in the vertical direction by shelves in the refrigerating chamber The storage space that is frequently used in the ice making room and the specific cooling room in the freezer storage room is less burdensome on the arm muscles of the user who is 75 cm or more and 115 cm or less in height from the refrigerator installation surface. Within the range Than is.

Invention of Claim 1 is the refrigerator main body formed with the heat insulation wall, the refrigerator compartment provided in the upper part of the refrigerator main body, the ice making chamber set to the freezing temperature zone provided in the lower part of the refrigerator compartment, A specific cooling room set in at least a freezing temperature zone arranged in parallel with the ice making room, and a freezing room and a vegetable room arranged below the ice making room and the specific cooling room arranged in parallel , the freezing room, the specific cooling A freezing storage room of three places, a storage room, an ice making room, and a storage space at a lowermost stage among a plurality of storage spaces partitioned in a vertical direction by shelves in the refrigerating room and a freezing storage room A storage space that is frequently used in the ice making room and the specific cooling room is stored in a range where the height from the refrigerator installation surface is 75 cm or more and 115 cm or less is less likely to burden the user's muscles. Yes, this range is the day Discovered from an ergonomic point of view that the arm muscles are less burdensome when a user with a standard height (157cm) of an adult female is standing and performing the operation of loading and unloading these frequently used items. The range of heights (illustration ergonomics, edited by the Japanese Standards Association, published in 1990), and articles that are frequently used in this range (eg eggs, small items, ice, daily foods, water tanks for ice making, etc.) When the user stands up and puts in and out these frequently used items by storing the lowermost storage space in the refrigeration chamber in which the product is stored and the storage space in the ice making chamber and the specific cooling chamber, Storing articles that are frequently used on a daily basis in a height zone that can be placed and removed with a natural posture as much as possible without imposing a strain on the muscles of the human body and ergonomically reducing the burden on the user By consolidating the pace, it can greatly improve the ease of use.

In order to solve the above-described conventional problems, the refrigerator of the present invention is set to a refrigerator body formed of heat insulating walls, a refrigerator room provided at the upper part of the refrigerator body, and a freezing temperature zone provided at the lower part of the refrigerator room. An ice making room, a specific cooling room set in at least a freezing temperature zone arranged in parallel with the ice making room, and a freezing room and a vegetable room arranged below the ice making room and the specific cooling room arranged in parallel. , A freezer compartment, a specific refrigerator compartment, and an ice making compartment, which are provided in three freezing storage compartments, and are used in the lowermost storage space that is partitioned by the bottom of the refrigerator compartment and the lowest shelf. And the storage space in the ice storage room and the specific cooling room, which are frequently used in the freezer storage room, are burdened on the arm muscles of the user having a height dimension of 75 cm or more and 115 cm or less from the refrigerator installation surface. contained within takes hard range, Furthermore, for the storage space in the ice making room and the specific cooling room, the height of the bottom surface of the refrigerator room from the refrigerator installation surface is 97 cm or less, so that the user can raise his elbow. Store the ice that is frequently used in the ice making chamber within the range that further reduces the burden on the ice, and store the frozen frozen food that is frequently used in the specific cooling chamber and that is stored in the freezing room. By storing frozen foods that have been stored for a long period of time, it is possible to sort and store frozen stocks that reduce the burden on the user according to the frequency of use .

As a result, this range was found from an ergonomic point of view that it was difficult for a Japanese standard height woman to stand up and put in and out of the arm muscles. This is a range, and when the user is in a standing posture, the user can put in and out the item in a natural posture without placing a burden on the arm muscles, greatly improving usability. it can.
