Description

  The present invention relates to a freezer compartment configuration of a refrigerator.

  Generally, a household refrigerator includes a refrigerator room, a freezer room, a vegetable room, and the like, and each room stores food and stores it in a cold state.

  Among them, the freezer compartment is provided with a support member on the inner surface of the door that is opened by drawer, and the support member is provided with a container so that the container is pulled out of the refrigerator body by pulling out the door and frozen food is taken in and out. It is easy to do.

  Further, the container is arranged in two upper and lower stages so that a large amount of frozen food can be stored and stored, so that it can cope with an increase in the amount of frozen food used due to changes in eating habits. (For example, refer to Patent Document 1).

  FIG. 10 shows a refrigerator described in Patent Document 1, and the freezer compartment of the refrigerator described in Patent Document 1 is provided with a support member 103 on the inner surface of a door 102 that can be pulled out from the refrigerator body 101. 103, the container 104 is arranged, and the container 104 is configured such that the upper container 104b is slidably installed in the opening of the lower container 104a. The upper container 104b has a shorter front-rear width than the lower container 104a, and an opening 105 is formed between the upper container 104b and the inner surface of the door when the door is pulled out.

JP 2008-196750 A

  The freezer compartment of the refrigerator described in Patent Document 1 makes it easy to put frozen food into and out of the upper and lower containers 104a and 104b, and can store the freezer compartment 106 above and below the freezer compartment 106. Can store and store many frozen foods. In addition, by storing frozen food stored in the lower container 104a for a relatively long time and storing frozen food to be used in a relatively short time in the upper container 104b, usability is improved, and frozen food is frequently used. It is useful for the user to do.

  However, in the above conventional refrigerator, the upper and lower containers 104a are used in spite of the fact that frozen foods stored in the upper and lower containers 104a and 104b are used for short-time storage and long-time storage as described above. 104b are cooled to substantially the same degree.

  Therefore, since the inside of the upper container 104b for storing frozen food used for short-time storage comes into contact with a large amount of outside air every time the frozen food is taken in and out, the cooling temperature tends to be higher than that in the lower container 104a.

  In addition, since the outside air also enters the lower container 104a from the opening 105 between the inner surface of the door 102 and the upper container 104b, the temperature in the lower container 104a varies greatly each time frozen food is taken in and out, which may affect the stored food. there were.

  Further, the cooling temperature in the upper container 104b tends to increase every time food is taken in and out, and in addition, outside air enters the lower container 104a from the opening 105 between the inner surface of the door 102 and the upper container 104b. Because the temperature rises, etc., it is necessary to set the cooling capacity of the freezer room higher in anticipation of these, and accordingly the cooling frequency that is driven by the compressor increases and the energy saving performance decreases. It was one of the causes. In particular, since the lower container 104a has a considerably larger volume than the upper container 104b, the influence of the lower container 104a is large because of the large amount of outside air entering.

  The present invention has been made in view of these points, and an object of the present invention is to provide a refrigerator having a freezing room capable of cooling suitable for short-term storage and long-term storage without reducing energy saving performance. is there.

  In order to solve the above-mentioned conventional problems, the present invention provides a freezer compartment provided in a refrigerator main body, a drawer-type door that opens and closes the freezer compartment, and a freezer compartment container that is taken in and out as the door is opened and closed. The freezer compartment container is composed of at least two upper and lower containers, and the upper container is slidably disposed above the lower container, the upper opening of the lower container is closed by the upper container, and the freezing A cold air outlet is opened on the back side of the upper and lower containers of the chamber, and the amount of cold air supplied from the cold air outlet into the upper container is set to be larger than the amount of cold air supplied into the lower container. .

  As a result, more cold air is supplied into the upper container of the freezer compartment than in the lower container, and the inside of the upper container that comes in contact with the outside air every time the door drawer is opened and closed can be rapidly cooled, and it takes a short time It can be used efficiently as a storage space. In addition, food can be stored in a frozen state. In addition, it is difficult for outside air from entering the inside of the lower container to maintain a stable cooling state with little temperature fluctuation, and the cold air supplied into the lower container is less likely to flow out of the lower container. The food in the container can be effectively cooled. Therefore, the inside of the lower container can be effectively used as a space for long-term storage. In addition, since the lower container has its upper opening closed by the upper container, the amount of outside air entering the lower container when the door is pulled out can be greatly reduced. Therefore, the cooling capacity of the freezer compartment can be reduced to a level that takes into account the amount of outside air entering the upper container, and energy saving is also improved.

  The refrigerator of this invention can be made into the refrigerator which improves energy-saving property by the said structure, and can preserve | save frozen food in the form suitable for each of short-time storage and long-time storage.

In addition, food can be stored in a frozen state. In addition, it is difficult for outside air from entering the inside of the lower container to maintain a stable cooling state with little temperature fluctuation, and the cold air supplied into the lower container is less likely to flow out of the lower container. The food in the container can be effectively cooled. Therefore, the inside of the lower container can be effectively used as a space for long-term storage. In addition, since the lower container has its upper opening closed by the upper container, the amount of outside air entering the lower container when the door is pulled out can be greatly reduced. Therefore, the cooling capacity of the freezer compartment can be reduced to a level that takes into account the amount of outside air entering the upper container, and energy saving is also improved.

FIG. 8 is an explanatory diagram showing the flow of cold air in the freezer compartment of the refrigerator, and FIG. 9 is an explanatory diagram showing the cold air flow in the freezer compartment portion of the refrigerator.

  First, the whole structure of a refrigerator is demonstrated.

  1 and 2, the refrigerator according to the present embodiment includes a refrigerator main body 1 having an opening at the front. The refrigerator main body 1 includes a metal outer box 2, a hard resin inner box 3, and the outside. A foam heat insulating material 4 filled with foam between the box 2 and the inner box 3 is formed, and a plurality of storage chambers are formed by the main body partition plate 5.

  Each storage chamber of the refrigerator main body 1 can be opened and closed by a pivotal or drawer type door 6, 7 to 9 adopting the same heat insulation structure as the refrigerator main body 1.

  The storage room formed in the refrigerator main body 1 includes an uppermost refrigerating room 10, a switching room 11 provided under the refrigerating room 10 and capable of switching a temperature zone, and an ice making room provided beside the switching room 11. 12, a switching room 11, an ice making room 12, and a freezing room 14 provided between the lowermost vegetable room 13.

  There is a cooling chamber 15 on the back of the freezing chamber 14, which includes a cooler 16 that generates cool air and a cooling fan 17 that supplies the cool air to each chamber, and further a defrosting means 18 is installed below the cooler 16. Has been.

  The cooler 16 constitutes a refrigeration cycle in which a compressor 19, a condenser (not shown), a heat radiating pipe (not shown), and a capillary tube (not shown) are connected in an annular shape. The cooling is performed by circulating the refrigerant compressed by the compressor 19.

  The cold air generated by the cooling chamber 15 is supplied and circulated to each room such as the refrigeration room 10 and the freezing room 14 through the cold air passage 20 to cool each room to a predetermined temperature.

  Next, a freezer compartment structure is demonstrated using FIGS.

  As shown in FIG. 3, the freezer compartment 14 attaches and fixes the support member 22 attached to the inner surface of the freezer compartment door 8 to the container-side rail 23a of the telescopic slide rail body 23 provided at the bottoms on both sides of the freezer compartment. The freezing chamber container 24 is held by the support member 22. The freezer compartment 24 can be taken in and out of the refrigerator main body 1 by pulling out and pushing in the door 8.

  As shown in FIGS. 4 and 5, the freezer compartment 24 has a two-stage configuration of a lower container 25 and an upper container 26. The upper container 26 slides the upper opening edge of the lower container 25 in the front-rear direction. It is arranged so that it can move freely. Then, a lower container cold air supply port 27 is formed to form a gap between the bottom rear surface of the upper container 26 and the rear upper end opening of the lower container 25 and supply cold air from a cold air outlet to be described later into the lower container 25. Is formed.

  In addition, the lower container 25 is provided with a partition plate 28 in the interior, and two left and right storage chambers 25a and 25b having different volumes are defined and formed on the front surface of the lower container 25, which is an upper part of the front surface thereof. A cold air outlet hole 29 is formed so as to be positioned above the cold air supply port 27.

  Of the storage chambers 25a and 25b formed in the lower container 25, a large-capacity storage chamber (hereinafter referred to as a large storage chamber) 25a covers the upper opening by disposing the upper container 26, Side surfaces, that is, the front surface of the lower container 25 shown in FIG. 4 and the like, the left side wall surface in the drawing, and the upper opening of the partition plate 28 in the lower container 25 are closed by the upper container 26.

  The other storage chamber (hereinafter referred to as a small storage chamber) 25b is capable of storing vertically frozen foods, plastic bottles, and the like that are taller than the bottom of the upper container 26, with the upper portion remaining open. . The small storage chamber 25b has a sufficiently small volume with respect to the large storage chamber 25a.

  Further, as shown in FIG. 7, a cold air outlet 30 for supplying cold air into the freezer compartment container 24 is provided in the back wall portion of the freezer compartment that houses the freezer compartment container 24.

  The cold air outlet 30 is divided into three parts for the upper container 26, for the large storage room 25 a of the lower container 25, and for the small storage room 25 b having the same height, and supplies cold air to the upper container 26. The cold air outlet 30a for the container is larger than the cold air outlet 30b for the lower container that supplies the cold air to the large storage chamber 25a of the lower container 25, and the cold air supplied into the upper container 26 enters the large storage chamber 25a of the lower container 25. It is set to be more than the cool air to be supplied.

  Further, the cold air outlet 30c for the small storage room for the small storage room whose height of the lower container 25 is high is provided at a position lower than the cold air outlet 30a for the upper container that supplies cold air into the upper container 26.

  In FIG. 7, reference numeral 31 denotes a cold air return port for returning the cold air after cooling the food to the cooling chamber 15 and is provided at the lower part of the back of the freezer compartment.

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

  First, the cooling operation of the refrigerator will be briefly described.

  The low-temperature cold air generated in the cooling chamber 15 is supplied from the cold air passage 20 to the refrigerating chamber 10 and the freezing chamber 14 by the cooling fan 17 to cool each chamber to a set temperature. Then, the cold air after cooling each chamber returns to the cooling chamber 15 again, is cooled by the cooler 16, and is circulated to each chamber by the cooling fan 17.

  The cold air to the refrigerator compartment 10 and the vegetable compartment 13 is controlled to be opened and closed by a damper (not shown), and is maintained and controlled in each set temperature range.

  Next, the cooling action of the freezer compartment 14 will be described.

  In the freezer compartment 14, cold air is supplied to the large storage chamber 25 a and the small storage chamber 25 b of the upper container 26 and the lower container 25 from the three cold air outlets 30 provided on the back of the freezer compartment, and cools the frozen food stored therein. To do.

  That is, as shown by the arrows in FIG. 8, the cold air from the cold air outlet 30a for the upper container is supplied into the upper container 26 to cool the food, overflows from the upper edge of the opening in the front part of the container, and Between them and the side wall of the freezer compartment, passes through the bottom bottom of the lower container 25, and circulates from the cold air return port 31 to the cooling chamber 15.

  In addition, the cold air from the lower container cold air outlet 30b flows from the lower container cold air supply port 27 between the upper container 26 and the lower container 25 into the large storage chamber 25a of the lower container 25, and after cooling the food, It flows out from the front cool air outflow hole 29 to the inside of the door 8, merges with the cool air from the upper container 26 and circulates from the cool air return port 31 to the cooling chamber.

Further, the cold air from the cold air outlet 30c for the small storage room is supplied to the small storage room 25b of the lower container 25 as shown in FIG. It flows out into the space, merges with the cold air from the upper container 26 and the large storage chamber 25a, and circulates from the cold air return port 31 to the cooling chamber.

  Here, since the upper container cold air outlet 30a for supplying cold air into the upper container 26 is larger than the lower container cold air outlet 30b, more cold air is supplied into the upper container 26 than in the lower container 25. . Therefore, it is possible to rapidly and strongly cool the inside of the upper container 26, which is in contact with outside air every time the door drawer is opened and closed, and the outside air enters and the temperature tends to increase. As a result, frozen foods that are frequently used and frequently put in and out can be cooled well, and can be efficiently used as a space for short-term storage of frozen foods. It can also be used as a space for quick freezing.

  Further, since the front wall / side wall surface of the upper container 26 is a non-porous wall surface without a cold air outflow hole, the cold air supplied into the upper container 26 overflows from the opening edge of the upper container 26. The entire inside of the container 26 can be rapidly cooled reliably.

  On the other hand, the upper container 26 is disposed in the upper opening of the large storage chamber 25a, and the upper opening is closed by the upper container 26. Therefore, the large storage chamber 25a of the lower container 25 is pulled out when the door is pulled out. It becomes difficult for outside air to enter inside, and the amount of outside air entering the large storage room 25a can be greatly reduced. Therefore, the inside of the lower container 25 can be maintained in a stable cooling state with little temperature fluctuation, and at the same time, the cooling capacity for cooling the freezer compartment 14 is low to a level that takes into account the amount of outside air entering the upper container 26. It is possible to reduce the cooling frequency for driving the compressor 19 and improve the energy saving performance.

  In addition, since the cold air in the large storage chamber 25a of the lower container 25 is blocked by the upper container 26, it is difficult for the cold air to flow out of the lower container 25. Accordingly, the frozen food stored in the large storage chamber 25a of the lower container 25 can be appropriately cooled even with a small amount of cold air coupled with the above stable cooling action, and is effective as a space for long-term storage of frozen food. Can be used for

  When the cool air supplied to the upper container 26 overflows from the upper opening edge and flows to the cool air return port 31 together with the outside air that has entered the upper container 26 when the door is pulled out, Therefore, it is possible to prevent the cold air having a relatively high temperature including the outside air from entering the large storage chamber 25a of the lower container 25. Therefore, also from this point, the cooling temperature in the lower container 25 can be stabilized and maintained at a low temperature, and the large storage room 25a of the lower container 25 can be effectively used as a long-time storage space for frozen food. .

  In this embodiment, the cold air outlet hole 29 provided in the front surface of the lower container 25 is a lower container cold air outlet 30b for supplying cold air to the large storage chamber 25a in the lower container 25 or a lower container cold air supply port. 27, the frozen food in the large storage chamber 25a can be stored in a better cooling state even if the amount of cold air is small.

  That is, with the above configuration, the cold air supplied into the large storage chamber 25a of the lower container 25 stays up to the height position of the cold air outflow hole 29, and then flows out of the cold air outflow hole 29 to be cooled at the back of the freezer compartment. Since it flows to the return port 31, the cold air in the large storage chamber 25a is not short-circuited to the cool air return port 31. Therefore, all of the cold air supplied into the large storage room 25a is used for food cooling, and the frozen food in the large storage room 25a can be well cooled and stored even if the amount of cold air is small.

The cooling efficiency is higher when all of the cool air outlet holes 29 are provided above the upper opening of the rear surface of the lower container, which is the lower end of the lower container cool air outlet 30b or the lower container cool air supply port 27. But you can.

  In addition, in this embodiment, in particular, the lower container 25 is provided with a partition plate 28 so as to be partitioned into two large and small storage chambers, and the upper storage chamber 25a is covered with the upper container 26 and the other small storage chamber 25b. Since the upper portion is open, food such as tall plastic bottles and vertically frozen food can be efficiently stored and stored frozen without being obstructed by the upper container.

  Moreover, the cold air outlet 30c for the small storage chamber that supplies cold air to the small storage chamber 25b that can store the frozen food having a high height is positioned lower than the cold air outlet 30a for the upper container that supplies cold air into the upper container 26. Since it is provided, the cold air from the cold air outlet 30c for the small storage chamber surely flows into the small storage chamber 25b without being dispersed toward the upper container 26. Therefore, the food stored in the small storage chamber 25b is more reliably cooled, and good frozen storage is possible.

  Although the embodiment of the present invention has been described above, the configuration described in the above embodiment is shown as an example for carrying out the present invention, and various modifications can be made within the scope of achieving the object of the present invention. Needless to say.

  For example, in this embodiment, the lower container 25 of the freezer compartment 24 is partitioned by a partition plate 28 to provide a large storage room 25a and a small storage room 25b, and an upper container 26 is installed in the upper opening of the large storage room 25a. Although an example in which only the upper opening is closed is illustrated, the lower container 25 may be installed as a single storage chamber in the upper opening without being partitioned by the partition plate 28.

  In addition, in this embodiment, a lower container that supplies cold air into the lower container 25 separately from the upper container cold air outlet 30a that supplies cold air into the upper container 26 as the cold air outlet 30 that supplies cold air to the freezer compartment 14. Although an example in which the cold air outlet 30b is provided is illustrated, the cold air outlet for supplying cold air into the lower container 25 is also used as the upper container cold air outlet 30a and is blown out from the upper container cold air outlet 30a. A part of the cold air may be supplied by being divided into the lower container 25. In this case, the lower container cold air supply port 27 formed in the back surface portion between the upper container 26 and the lower container 25 becomes the lower container cold air outlet 30b for supplying cold air into the lower container 25. is there.

  The refrigerator according to the present invention can be a refrigerator that can store food frozen in a form suitable for short-time storage and long-time storage while improving energy saving, and can be widely applied to commercial refrigerators as well as household refrigerators. be able to.
