Description

Refrigerator with a refrigerator body

Technical Field

The present invention relates to a refrigerator, and more particularly, to a refrigerator that blows cool air to a container accommodated in a storage compartment.

Background

In a conventional refrigerator, a storage container is disposed in a refrigerator compartment, as described in patent document 1 (japanese patent application laid-open No. 2018-44687). Wherein, the lowest part of the refrigerating chamber is accommodated with a fresh ice (chilled) container. The cool air blown by the blower is supplied to the refrigerating chamber through an air supply path formed at the rear side of the refrigerating chamber. The cool air blown through the air supply path is partially blown directly to the fresh air container without passing through the refrigerator compartment. In this way, the temperature in the container of the fresh ice container is lower than the indoor temperature of the refrigerating chamber, for example, at about 0 ℃. In this way, the food such as meat stored in the frozen fresh container can be stored while maintaining the original freshness.

However, in the refrigerator described in patent document 1, there is room for improvement in maintaining the freshness of the food stored in the fresh ice container.

Specifically, in order to continuously maintain the freshness of the food stored in the fresh ice container for a long period of time, the indoor temperature of the fresh ice container is preferably kept constant at a low temperature of about-3 ℃ so that the food in the container is not completely frozen. However, when cool air of about-15 ℃ is introduced into the fresh ice container in order to reduce the indoor temperature of the fresh ice container, the introduced cool air may be directly blown onto the food, and thus, it is difficult to maintain the freshness, and the food may be finally frozen.

In order to cope with this problem, it is considered to cool the fresh ice container from the top surface side. However, in the case of manufacturing the top surface of the fresh ice container with a transparent member such as glass for securing visibility, there arises a problem that it is difficult to form an air passage on the top surface side.

Disclosure of Invention

The present invention has been made in view of the above-described problems, and an object thereof is to provide a refrigerator capable of continuously maintaining freshness of foods stored in a storage container for a long period of time.

The refrigerator of the present invention includes: a cooling chamber accommodating a cooler for cooling air; a wind-sending path for blowing cool air from the cooling chamber to the storage chamber; a storage container disposed inside the storage chamber; and an inlet port through which the cool air is introduced into the container; and an air duct cover plate disposed at a position facing the inlet inside the storage container.

According to the refrigerator of the present invention, the freshness of food stored in the storage container forming the fresh ice compartment or the like can be maintained continuously for a long period of time. Specifically, the duct cover is disposed in the container at a position facing the inlet, and thereby prevents cold air from being directly blown into the container of the container from the inlet. Thus, the food such as meat stored in the storage container is not directly blown with cool air, and the food can be prevented from being dehydrated and dried.

In addition, in the refrigerator of the present invention, it further includes a heat insulating member that is disposed between the air path cover plate and the introduction port and is made of a material having heat insulating property superior to that of the air path cover plate.

According to the refrigerator of the present invention, the heat insulating member is disposed between the air duct cover and the inlet, so that the direct collision of the cool air against the air duct cover is suppressed, and therefore, the front surface of the air duct cover can be suppressed from becoming hazy.

In the refrigerator according to the present invention, the heat insulating member has a side inclined surface which is a surface of the heat insulating member facing the inlet and is inclined in a direction to the side and away from the inlet.

According to the refrigerator of the present invention, the side end of the heat insulating member is inclined, so that the cool air introduced from the inlet can flow laterally. This makes it possible to uniformly cool the side end portions of the storage container and to prevent cold air from directly blowing onto the storage objects.

In the refrigerator according to the present invention, the heat insulating member may have a lower inclined surface, which is a surface of the heat insulating member facing the inlet, and may be inclined downward and in a direction away from the inlet.

According to the refrigerator of the present invention, the cool air introduced from the inlet can be flowed downward by making the lower end of the heat insulating member inclined. This makes it possible to uniformly cool the storage container from top to bottom, and to suppress direct blowing of cold air onto the storage article.

In the refrigerator according to the present invention, a bottom surface of the storage container is provided with a metal plate, and a part of the cool air introduced into the storage container is blown onto the metal plate.

According to the refrigerator of the present invention, cool air can be blown onto the metal plate disposed on the bottom surface of the storage container and the stored object can be cooled by the metal plate, so that the stored object can be cooled more effectively.

Detailed Description

A refrigerator 10 according to an embodiment of the present invention will be described in detail based on the drawings. In the description of the present embodiment, the same reference numerals are used for the same components in principle, and repetitive description thereof will be omitted. In the following description, the directions of up, down, front, rear, left and right are used, but the directions are the directions when the refrigerator 10 is viewed from the front.

Fig. 1 is a perspective view of the refrigerator 10 seen from the left front. The refrigerator 10 has a heat-insulating box 11 and a storage compartment formed inside the heat-insulating box 11. As the storage compartments, there are a refrigerating compartment 12 and a freezing compartment 13 from top to bottom. The front opening of the refrigerating compartment 12 is closed by a rotary heat-insulating door 18 and a heat-insulating door 19. The front surface opening of the freezing chamber 13 is closed by a heat insulating door 20 and a heat insulating door 21. The heat-insulating doors 18, 19, 20, and 21 are rotatable doors, and are rotatable about outer side ends in the lateral direction as rotation axes.

Fig. 2 is a front view of the refrigerator 10 showing the heat insulating doors 18, 19, 20, and 21 in an open state.

A storage container 25 and a storage container 26 are disposed at the lower portion of the refrigerating chamber 12. The storage containers 25 and 26 are substantially box-shaped containers made of synthetic resin, and are provided so as to be capable of being pulled out in the front-rear direction. The interior of the storage container 25 serves as a fresh ice container cooled to a temperature range of about-3 ℃. The interior of the storage container 26 serves as a container for storing vegetables and the like at a low temperature cooled to about 2 ℃. The indoor temperature of the refrigerating chamber 12 in the portion other than the storage container 25 and the storage container 26 is in the refrigerating temperature range of, for example, 3 ℃ to 5 ℃. A water supply tank 24 for storing water supplied to the ice maker is disposed on the left side of the storage container 26. The heat insulating doors 18 and 19 are provided with a storage basket 17 for storing beverages, seasonings, and the like on the inner side surfaces thereof.

The freezing chamber 13 accommodates a plurality of storage containers 32. Here, 6 containers 32 are arranged in a matrix. Each of the storage containers 32 can be pulled out in the front-rear direction. The indoor temperature of the freezing chamber 13 is in a freezing temperature region of, for example, -20 ℃ to-18 ℃. An automatic ice maker, not shown in the drawings, is disposed inside the freezing chamber 13. The automatic ice maker makes ice by freezing water supplied from the aforementioned water tank 24.

The sectional structure of the refrigerator 10 is explained with reference to a side sectional view of fig. 3. The flow of cold air with respect to the inside of the refrigerator 10 is shown with dotted arrows in fig. 3.

The heat insulating box 11 is constituted of: an outer case 111 made of a steel plate bent to a prescribed shape; an inner case 112 made of a synthetic resin plate, which is disposed inside a certain distance from the outer case 111; and a heat insulating material 113 filled between the outer case 111 and the inner case 112.

As described above, the storage compartment inside the heat-insulating box 11 is divided into the refrigerating compartment 12 and the freezing compartment 13 from top to bottom. The refrigerating chamber 12 and the freezing chamber 13 are divided by a heat insulating wall 27.

The inside of the refrigerating chamber 12 is partitioned by a plurality of storage shelves 15 in the up-down direction. A storage shelf 152 is disposed above the storage container 26 disposed at the lowermost portion of the refrigerating compartment 12. A storage container 25 is disposed above the storage shelf 152, and an upper opening of the storage container 25 is covered with a storage shelf 151. As described above, the inside of the storage container 26 serves as a vegetable room, and the inside of the storage container 25 serves as an ice fresh room.

The storage shelf 151 covering the upper surface of the inside of the storage container 25 is made of a transparent plate material such as a glass plate. Since the storage shelf 151 is made of a transparent plate material, the user can see the food stored in the storage container 25 through the storage shelf 151 even without pulling the storage container 25 forward.

A cooling chamber 115 is formed on the inner side of the freezing chamber 13, and the freezing chamber 13 and the cooling chamber 115 are partitioned by a partition wall 28. An evaporator 116 as a cooler is disposed in the cooling chamber 115. The refrigerator 10 is divided into a machine room 14 at the rear side of the lower end, and a compressor 22 is disposed in the machine room 14. The evaporator 116 and the compressor 22, as well as a condenser and an expansion device, not shown herein, together form a vapor compression refrigeration cycle. By operating the vapor compression refrigeration cycle, the cool air inside the cooling chamber 115 is cooled by the evaporator 116, and the cool air is blown to each storage chamber, whereby the indoor temperature of each storage chamber becomes a specified cooling temperature region.

A blower 29 is disposed inside the cooling chamber 115 above the evaporator 116. The blower 29 is an axial flow fan or a centrifugal fan, and blows cool air cooled by the evaporator 116 toward the refrigerating compartment 12 and the freezing compartment 13.

Inside the cooling chamber 115, a defrosting heater 117 is disposed below the evaporator 116. With the operation of the vapor compression refrigeration cycle, thick frost is formed on the surface of the evaporator 116. When this occurs, a control device, not shown, stops the compressor 22, and energizes the defrost heater 117 to heat it, thereby performing a defrosting operation of melting and defrosting.

An air blowing path 118 is formed upward from the cooling chamber 115. The air-sending passage 118 is formed with an air outlet 23 as an opening for blowing cool air to the refrigerating chamber 12. Cool air is blown forward from the air outlet 23. The air passage damper 31 is installed in the middle of the air passage 118, and the structure related thereto is described later with reference to fig. 4A.

As will be described later, the cool air is directly sent to the storage container 25 from an air passage formed separately from the air blowing passage 118. Thereby cooling the interior of the storage container 25 to the freezing temperature range. The structure related thereto is described later with reference to fig. 8A and the like.

Part of the cool air blown out from the air outlet 33 is not introduced into the storage container 25 through the inlet 34, but flows downward after traveling forward between the storage container 25 and the storage shelf 152. Further, the cool air blown out into the inside of the storage container 25 from the inlet 34 is blown out forward from the opening formed at the front end of the storage container 25 after cooling the inside of the storage container 25, and then flows downward.

The container 26 is a semi-closed container. That is, the storage container 26 is not formed with an opening for actively introducing or discharging cool air. As described above, a part of the cool air blown out from the air outlet 33 flows downward inside the refrigerator compartment 12, and surrounds the storage container 26 from the outside. In this way, the container internal temperature of the storage container 26 is maintained in a refrigerating temperature zone lower than the representative indoor temperature of the refrigerating chamber 12.

A part of the cool air blown by the blower 29 is blown to the freezing chamber 13 via the air blowing port 41 as an opening formed in the partition wall 28. Cool air that cools the inside of each container disposed in the freezing compartment 13 is returned to the cooling compartment 115 from the return air inlet 42. Thereby cooling the freezing chamber 13 to a designated freezing temperature interval.

Fig. 4A is a front view showing the structure of the air blowing path 118 and the like, and fig. 4B is a front view showing the refrigerating chamber 12, the air blowing path 118 and the like of the refrigerator 10.

Referring to fig. 4A and 4B, the air outlet 16 is formed by opening at the side and upper end portions of the air blowing path 118. Cool air passing through the heat insulating door 18 is blown out from the air outlet 16 into the interior of the refrigerator compartment 12.

A duct damper 31 is installed at a lower portion of the air duct 118. The temperature of the refrigerating chamber 12 is detected by a temperature sensor of the refrigerating chamber 12, not shown in the drawings, and the temperature of the refrigerating chamber 12 is cooled to a specified refrigerating temperature zone by opening and closing the air path damper 31.

The air duct 119 is an air duct branching from the middle portion of the air duct 118 to the right and upward. A duct damper 30 is installed at the lower portion of the air duct 119. A temperature sensor that detects the temperature in the container of the storage container 25 is installed in the air-sending passage 119. The air duct damper 30 is opened and closed based on the detected temperature detected by the associated temperature sensor, so that the container internal temperature of the storage container 25 becomes a predetermined fresh ice temperature zone.

Referring to fig. 4B, an air outlet 33 and an inlet 34 are formed at an upper end of the air supply path 119. The cool air blown upward through the air-sending passage 119 is directly blown to the storage container 25 through the air outlet 33 and the inlet 34. The structures and the like of the air outlet 33 and the introduction port 34 are described later with reference to fig. 5 and the like.

An air outlet 40 is formed in the middle of the air supply duct 118. The air outlet 40 is an opening for blowing cool air rising in the air blowing path 118 to the refrigerating compartment 12 above the storage shelf 151. When the refrigerator compartment 12 is opened, condensation may adhere to the surface of the storage shelf 151. Since the cool air blown from the air outlet 40 flows on the upper surface of the storage shelf 151, dew condensation adhering to the surface of the storage shelf 151 can be eliminated even in such a case.

Fig. 5 is a side cross-sectional view showing a portion of the interior of the refrigerator compartment 12 where the air outlet 33 and the inlet 34 are disposed.

The air outlet 33 is an opening formed in the heat-insulating box 11 for blowing cool air flowing through the air blowing path 119 to the storage container 25. The air outlet 33 has a substantially rectangular shape when viewed from the front, and a rib 39 is disposed at the front end thereof. The ribs 39 are plate-like members extending substantially horizontally, and are arranged in plural at substantially equal intervals in the up-down direction.

The inlet 34 is formed by opening a substantially rectangular opening in the rear side surface of the storage container 25. The inlet 34 is formed larger than the outlet 33. Specifically, the inlet 34 is formed longer than the outlet 33 in the up-down direction and the left-right direction. That is, in a state in which the storage container 25 is stored in the refrigerator compartment 12, the upper end of the inlet 34 is disposed above the upper end of the air outlet 33, the lower end of the inlet 34 is disposed below the lower end of the air outlet 33, the left end of the inlet 34 is disposed on the left side of the left end of the air outlet 33, and the right end of the inlet 34 is disposed on the right side of the right end of the air outlet 33.

In this way, most of the cool air blown out from the air outlet 33 can be introduced into the container of the storage container 25 through the inlet 34, and the container of the storage container 25 can be cooled effectively.

At the inlet 34, an air duct cover 35 is mounted from the front side, and a rear member 38 is mounted from the rear side.

The duct cover 35 is disposed in the storage container 25 at a position facing the inlet 34. The duct cover 35 is made of a synthetic resin plate formed in a substantially cover-like manner. The specific structure and the like of the air path cover plate 35 are described later with reference to fig. 6 and 7.

The rear member 38 is a synthetic resin member attached from the rear side to the inlet 34 of the storage container 25, and has an opening for the circulation of cool air. The specific structure of the rear member 38 is described later with reference to fig. 6 and 7.

The heat insulating member 36 is disposed between the duct cover 35 and the inlet 34. The heat insulating member 36 is made of a material having heat insulating properties superior to those of the air duct cover 35, for example, a foamed resin such as foamed polystyrene. The specific structure of the heat insulating member 36 is described later with reference to fig. 6 and 7.

The bottom surface of the storage container 25 is provided with a metal plate 37 made of, for example, aluminum or stainless steel. The food stored in the storage container 25 is disposed on the upper surface of the metal plate 37.

The duct cover 35 and the rear member 38 are fitted together through the inlet 34. The duct cover 35 is fitted to the rear member 38 with the heat insulating member 36 incorporated therein.

Fig. 6 is an exploded perspective view of the case of the duct cover 35 and the like seen from the front. Fig. 7 is an exploded perspective view of the case of the duct cover 35 and the like seen from the rear. Although not shown here, a filter device is disposed between the heat insulating member 36 and the rear member 38. For example, a bag-like nonwoven fabric containing deodorizing beads, a honeycomb-shaped filter paper, or the like may be used as the filter device. By providing the filter device, the cool air can be deodorized, and intrusion of dust and the like into the storage container 25 can be suppressed.

Referring to fig. 6, the rear member 38 is a generally cap-like member having a forward opening. An outer sidewall portion 383 is formed around the front surface of the rear member 38. The outer wall 383 is a portion of the outer peripheral portion of the rear member 38 protruding forward in a wall shape. The outer wall 383 is a portion to be fitted to the duct cover 35.

The upper opening 381 and the lower opening 382 are openings formed substantially in the center in the left-right direction of the rear member 38. The cool air is introduced into the storage container 25 through the upper opening 381 and the lower opening 382.

As shown in fig. 7, the upper opening 381 is formed as a plurality of slits. With this configuration, the user's hand can be prevented from coming into contact with the filter device while entering the back side of the upper opening 381. As shown in fig. 6, the upper opening 381 is surrounded by a wall portion. Specifically, the upper opening 381 is enclosed by an opening wall 384, an opening wall 385, and an opening wall 386. The opening wall portion 384, the opening wall portion 385, and the opening wall portion 386 are portions that are provided upright from the front surface of the rear member 38. With such a structure, a filter device, not shown here, can be disposed in an area surrounded by the opening wall 384, the opening wall 385, and the opening wall 386.

As shown in fig. 7, the lower opening 382 is formed as a substantially rectangular opening. The lower opening 382 is formed below the upper opening 381.

As shown in fig. 6, the heat insulating member 36 is built in a space formed by the rear member 38 and the duct cover 35. Referring to fig. 7, the heat insulating member 36 has a flat surface 364, a side inclined surface 361, a side inclined surface 362, and a lower inclined surface 363 on the rear surface thereof facing the inlet 34.

The flat surface 364 is a flat surface formed in an upper portion of the rear surface of the heat insulating member 36, which is centered in the left-right direction. The flat surface 364 is substantially perpendicular to the flow of the cold air introduced through the upper opening 381.

The side inclined surface 361 is a surface inclined rightward and forward. The side inclined surface 361 is formed between the right side edge of the heat insulating member 36 and the flat surface 364. The side inclined surface 361 is a portion where the cold air introduced from the upper opening 381 flows rightward.

The side inclined surface 362 is a surface inclined leftward and forward. The side inclined surface 362 is formed between the left side edge of the heat insulating member 36 and the flat surface 364. The side inclined surface 362 is a portion for allowing cool air introduced from the upper opening 381 to flow leftward.

The lower inclined surface 363 is a portion inclined downward and forward so that the heat insulating member 36 faces the inlet 34. The lower inclined surface 363 is formed between the lower side surface of the heat insulating member 36 and the flat surface 364. The lower inclined surface 363 is a portion for allowing the cold air introduced from the lower opening 382 to flow downward.

As shown in fig. 7, the duct cover 35 is a substantially cover-shaped member that opens rearward. The duct cover 35 has a side opening 351, a side opening 352, and a lower opening 353.

The side opening 351 is formed by opening on the right side surface of the duct cover 35. The cool air flowing along the side inclined surface 361 of the heat insulating member 36 is blown out from the side opening 351 into the storage container 25.

The side opening 352 is formed by opening on the left side surface of the duct cover 35. The cool air flowing along the side inclined surface 362 of the heat insulating member 36 is blown out from the side opening 352 into the storage container 25.

The lower opening 353 is formed by opening to the lower surface of the duct cover 35. The cool air flowing along the lower inclined surface 363 of the heat insulating member 36 is blown out from the lower opening 353 into the storage container 25.

Here, the upper surface of the duct cover 35 is not formed with an opening. That is, the cool air is not blown upward from the duct cover 35. Referring to fig. 3, in this way, the storage shelf 151, which is a glass plate covering the storage container 25 from above, is prevented from becoming hazy.

Fig. 8A is a side cross-sectional view showing the flow of cool air blown out from the inlet 34 to the storage container 25.

First, cool air cooled by the evaporator 116 in the cooling chamber 115 shown in fig. 3 is blown upward in the air blowing path 119 by the blowing force of the blower 29. The cool air flowing through the air blowing path 119 is blown out forward from the air outlet 33. At this time, the cool air is blown out substantially horizontally along the ribs 39.

Thereafter, the cool air is blown out from the air outlet 33 to the storage container 25. As described above, the inlet 34 of the storage container 25 is formed larger than the outlet 33. Thus, most of the cool air blown out from the air outlet 33 is introduced into the container of the storage container 25 through the inlet 34. This allows the temperature in the container 25 to be cooled to a temperature range of-3.+ -. 1 ℃.

The opening wall 385 is disposed at the inlet 34. The opening wall 385 is inclined forward and downward. So that a part of the cool air blown out from the air outlet 33 flows downward, and the metal plate 37 described later can be cooled effectively.

As described above, the heat insulating member 36 is attached to the rear of the duct cover 35. Thus, the cool air introduced into the storage container 25 from the inlet 34 collides with the rear surface of the heat insulating member 36, and does not blow onto the duct cover 35. Thereby, the air path cover plate 35 is prevented from being directly cooled by the cold air, and the front surface of the air path cover plate 35 can be prevented from becoming cloudy or dew formation occurring. If the front surface of the duct cover 35 becomes blurred or dew condensation occurs, there is a fear that the front surface is visually unclean. In this embodiment, the sense of cleanliness can be improved by avoiding such cloudiness or dew condensation.

A part of the cool air blown out from the air outlet 33 collides against the lower inclined surface 363 formed at a portion below the front surface of the heat insulating member 36, and is then guided downward. Thereafter, the cool air travels downward and forward through the lower opening 353 of the duct cover 35, and collides with the upper surface of the metal plate 37. Thereafter, the cool air advances forward along the upper surface of the metal plate 37. In this way, the internal space of the storage container 25 and the stored object are finally cooled by the metal plate 37.

Fig. 8B is a cross-section corresponding to the A-A cross-section line of fig. 8A, and is an upper cross-sectional view showing the flow of cold air along the heat insulating member 36. A part of the cool air introduced from the air outlet 33 to the inlet 34 collides with the flat surface 364, and then travels along the side inclined surface 361 and the side inclined surface 362 to the left and right, and is blown out into the container of the storage container 25 from the side surface of the storage container 25.

Fig. 9A is a perspective view showing the flow of cool air blown out from the duct cover 35. Fig. 9B is a perspective view showing the flow of cold air inside the storage container 25. The cold air flow is shown with dashed arrows in fig. 9A, and with white arrows in fig. 9B.

Referring to fig. 9A, the cold air guided to the right by the side inclined surface 361 shown in fig. 8B is blown out into the container of the storage container 25 through the side opening 351 of the duct cover 35. The cold air guided to the left by the side inclined surface 362 shown in fig. 8B is blown out into the container of the storage container 25 through the side opening 352 of the duct cover 35. Further, the downward cold air is guided by the downward inclined surface 363 shown in fig. 8A to blow into the container of the storage container 25 through the downward opening 353.

Referring to fig. 9B, cool air is blown out leftward and rightward from the duct cover 35, and the inside of the storage container 25 can be cooled uniformly from the surroundings. Further, the cool air is blown downward from the duct cover 35. This directly cools the metal plate 37, and can effectively cool the food placed on the metal plate 37. Further, the storage container 25 can be cooled uniformly until the lower end portion thereof.

On the other hand, the cool air is not blown forward from the duct cover 35. Thus, cool air at about-15 ℃ is not directly blown onto the food or the like stored in the storage container 25, and it is possible to prevent the surface of the food from being dehydrated, dried or frozen, and to prevent the freshness of the food or the like from being lowered. Further, the cool air is not blown upward from the duct cover 35. Thus, the cold air does not blow onto the storage shelf 151 shown in fig. 3, and thus, even if a device such as a heater is not exclusively mounted on the storage shelf 151, the cold air is prevented from becoming cloudy or dew condensation.

The present invention is not limited to the above-described embodiments, but various embodiments are possible within the scope not departing from the gist of the present invention.

Specifically, the temperature of the fresh ice container can be controlled to-3±1 ℃ by providing the amount of cool air blown out into the fresh ice chamber formed inside the storage container 25, and providing a dedicated air duct and an air duct damper separately provided from the refrigerating chamber 12. In this way, the temperature variation of the food stored in the storage container 25 can be reduced, and the evaporation amount of moisture can be reduced, thereby enabling better freshness to be maintained.
