Description

  The present invention relates to a refrigerator, and more particularly, to a cold-cooled refrigerator that cools a plastic bottle disposed in the front part of a vegetable room.

  The refrigerator includes a plurality of storage rooms such as a vegetable room and a cooler that generates cool air for cooling each storage room, and conventionally, an intercooled refrigerator is often used. During the cooling of the vegetable compartment in the cold refrigerator during this time, the cool air generated by the cooler circulates behind, below and in front of the container placed inside the vegetable compartment. Specifically, the cool air is sent from the upper rear side of the container to the lower part, passes through the lower part of the bottom part of the container toward the front, and then is sent upward from the lower part of the front of the container. Thereby, the vegetable accommodated in the said container is cooled. And cold air returns to a cooler through the air passage arranged in the vegetable room upper part (for example, refer to patent documents 1).

  In addition, the container placed inside the vegetable room is provided with a lid, and the cold air generated by the cooler circulates around the outer periphery of the container including above the lid, so that the vegetables contained in the container are cooled. A refrigerator is also proposed (see, for example, Patent Document 2).

JP-A-8-233430 JP-A-11-304354

  In recent years, there has been a desire to cool storage products having a relatively high height, for example, beverage bottles (hereinafter referred to as PET bottles) made of polyethylene terephthalate. For this reason, the front part of the vegetable room is provided with a space for accommodating a relatively high plastic bottle because it can be easily taken out and a space can be secured.

  Here, when vegetables are cooled excessively, there is a risk that low temperature damage such as a decrease in freshness may occur. For this reason, the vegetable room is set to a relatively high temperature in the storage room. Moreover, it is desirable that the plastic bottle is cooled at a temperature lower than that of the vegetables.

  However, in the conventional refrigerator, cold air circulates outside the container disposed inside the vegetable room, thereby cooling the vegetable and the plastic bottle. For this reason, there exists a problem that vegetables and a PET bottle are cooled only to comparable temperature.

  Moreover, in the refrigerator currently disclosed by patent document 1, the cool air of a cooler may flow back into a vegetable room through the air path arrange | positioned at the vegetable room upper part. In this case, there is also a problem that a low temperature failure such as a decrease in the freshness of vegetables cooled by this cold air occurs.

  Therefore, the present invention has been made in view of such problems, and a refrigerator capable of cooling both a plastic bottle that is desired to be cooled and a vegetable that is desired to be overcooled in a vegetable room. The purpose is to provide.

  In order to solve the above-described conventional problems, the refrigerator of the present invention includes an outer box, an inner box, a heat insulating box formed of a heat insulating material provided between the outer box and the inner box, and the inner side of the heat insulating box. A refrigerator comprising: a cooler that cools air and generates cold air; and a lower storage chamber that is formed inside the heat insulation box and is disposed below the cooler. A storage space provided by partitioning the chamber, the front space disposed in the front and having the opening surface on the upper side and the rear space disposed in the rear, and the cool air generated by the cooler passes through the front space An opening disposed above the space, and an air passage forming body that forms an air passage connecting the opening and the cooler are provided.

  Accordingly, the opening is disposed above the front space in the front portion of the lower storage chamber. For this reason, since the cool air of the cooler flows backward through the air passage forming body, the cool air flows from the upper opening portion of the front space through the opening surface, so that the front space is cooled by the cool air. Therefore, if the PET bottle is accommodated in the front space, the PET bottle is cooled. Further, the cold air that flows backward through the air passage forming body flows toward the front space. For this reason, since the cold air | flow which flows backward does not flow easily into the back space behind the lower storage room, if the vegetable is accommodated in back space, the said vegetable will not be cooled excessively. Thereby, the plastic bottle which wants to cool and the vegetable which wants to suppress overcooling can be cooled in a compatible manner.

  Since the refrigerator of the present invention can provide a refrigerator capable of cooling both a plastic bottle to be cooled and a vegetable to be excessively cooled in the vegetable room, the practical value of the present invention can be provided. Is extremely expensive.

  The invention according to claim 1, cools the air inside the heat insulating box by cooling the air inside the heat insulating box and the heat insulating box formed by the outer box, the inner box, the outer box and the inner box. A refrigerator comprising: a cooler to be generated; and a lower storage chamber which is a storage chamber formed inside the heat insulating box and disposed below the cooler, and is provided by partitioning the lower storage chamber A housing space, which is disposed in front and has a front space having an opening surface above and a rear space disposed in the rear, and cool air generated by the cooler passes and is disposed above the front space. By providing an opening and an air passage forming body that forms an air passage connecting the opening and the cooler, the opening is disposed above the front space of the front portion of the lower storage chamber. For this reason, since the cool air of the cooler flows backward through the air passage forming body, the cool air flows from the upper opening portion of the front space through the opening surface, so that the front space is cooled by the cool air. Therefore, if the PET bottle is accommodated in the front space, the PET bottle is cooled. Further, the cold air that flows backward through the air passage forming body flows toward the front space. For this reason, since the cold air | flow which flows backward does not flow easily into the back space behind the lower storage room, if the vegetable is accommodated in back space, the said vegetable will not be cooled excessively. Thereby, the plastic bottle which wants to cool and the vegetable which wants to suppress overcooling can be cooled in a compatible manner.

  The invention according to claim 2 is the invention according to claim 1, further comprising a container disposed inside the lower storage chamber, wherein the front space is disposed in a front part inside the container. The container is provided with a front wall having an insertion hole through which cold air can be inserted in the front portion, so that when the cold air returns to the cooler, it passes through the insertion hole provided in the front wall of the container and enters the front space. If a plastic bottle is accommodated in the front space, the plastic bottle can be cooled. Moreover, since cold air | flow flows toward the opening part arrange | positioned above the front space, this cold air does not flow easily into the rear space of the rear part of the lower storage chamber. Therefore, if the vegetables are accommodated in the rear space, the vegetables are not cooled too much. Thereby, the plastic bottle which wants to cool and the vegetable which wants to suppress overcooling can be cooled in a compatible manner.

  The invention according to claim 3 is the invention according to claim 1, further comprising a fruit / small article container disposed in an upper portion of the rear space, wherein the opening is formed from a front end surface of the fruit / small article container. Since the opening is arranged in front of the front end face of the fruit / small container, the opening is blocked by food contained in the fruit / small container, and the circulation of cold air is prevented. Inhibition can be prevented, and PET bottles that are desired to be cooled and vegetables that are desired to be overcooled can be cooled in a compatible manner. In particular, since fruits and small items are preserved in temperate regions such as bananas, eggplants, and cucumbers and are prone to low-temperature damage, they prevent the cold air from flowing back and prevent excessive cooling. is there.

  The invention according to claim 4 is the invention according to claim 1, further comprising a container disposed inside the lower storage chamber, wherein the air passage forming body is provided on a side surface of the lower storage chamber. Even when the opening is closed, the preliminary opening provided on the side surface of the air passage forming body is provided with the preliminary opening disposed outside the side surface of the container. A limited amount of cool air can flow in, and the cold air circulation can be prevented from being hindered. Moreover, since the preliminary opening is arranged outside the side surface of the container, food such as vegetables stored in the container is not overcooled even if the cold air flows backward. Therefore, it is possible to cool both the PET bottle that is desired to be cooled and the vegetable that is desired to be overcooled.

  According to a fifth aspect of the present invention, in the first aspect of the invention, the air passage forming body is provided with ribs in parallel with the flow direction of the cold air, so that the flow of the cold air is not significantly inhibited. A relatively hard storage item such as an apple that is a storage item of a fruit / small item container, which protrudes slightly in the height direction from the fruit / small item container (that is, a storage item whose height is higher than the height of the fruit / small item container) When the fruit / small container moves toward the rear of the vegetable room and a relatively hard container such as an apple comes into contact with the air passage formation body, the shape of the air passage formation body is deformed. Since it is difficult to prevent the air flow and the air passage through which the cold air flows can be ensured, the circulation of the cold air is not hindered.

  FIG. 4 is a front view showing the inside of the vegetable compartment of the refrigerator in Embodiment 1 of the present invention. For convenience of explanation, the fruit / small article container 420 is omitted in FIG.

  As shown in FIG. 4, an opening 450 a is provided in the front surface portion 451 of the air path forming body 450. The opening 450 a is an opening serving as an inlet of the air passage forming body 450 through which the cold air that has cooled the inside of the vegetable compartment 103 returns to the cooler 200. The lateral width of the opening 450a is desirably large enough to prevent a child's finger from entering, and is specifically 5 mm.

  Specifically, the opening 450 a is a vertically long elliptical opening, and a plurality of openings 450 a are provided in the lateral direction on the front surface 451 of the air passage forming body 450. The opening 450a may have any shape as long as it is an opening through which cold air passes, and any number may be provided.

  Here, the flow of cold air to the refrigerator compartment 102 and the vegetable compartment 103 will be described.

  The room is cooled to a predetermined temperature by forcibly blowing cool air generated by the cooler 200 to the refrigerating room 102 through a cooling duct cooling air duct (not shown). The room is cooled to a predetermined temperature by forcibly blowing a blower to the vegetable room 103 through a communication duct (not shown) that sends cold air from the refrigerator compartment 102 to the vegetable room 103. This communication duct is an air passage that connects an opening (not shown) provided in the lower part of the back of the refrigerator compartment 102 and an opening provided in the upper part of the back of the vegetable compartment 103 up and down. And it flows into the vegetable compartment 103 from the opening part 470 provided in the lower part of the back part of the vegetable compartment 103. FIG. In addition, the opening provided in the upper part of the back part of the vegetable compartment 103 and the opening part 470 provided in the lower part of the back part of the vegetable compartment 103 form the air path connected up and down by the vegetable compartment discharge duct 480. . In addition, this communication duct is arrange | positioned on the right side from the center of a refrigerator, and the opening part 470 provided in the lower part of the back part of the vegetable compartment 103 is also arrange | positioned on the right side from the center of the refrigerator.

  Moreover, as shown in FIG. 4, the air path formation body 450 is arrange | positioned at the left side of the left-right direction of a refrigerator, and the dimension of the width direction (left-right direction of FIG. 4) of the air path formation body 450 is the vegetable compartment 103. Is set to be approximately ½ in the horizontal direction. The opening 450a is formed over substantially the entire width direction of the air path forming body 450. Thereby, the opening part 470 provided in the right side of the lower part of the back part of the vegetable compartment 103, and the opening part 450a provided in the left side of the upper part of the front part of the vegetable compartment 103 are diagonally located in the vegetable compartment. As a result, the air is distributed almost uniformly in the left-right direction of the vegetable compartment 103, and the cooling capacity of the vegetable compartment 103 can be secured.

  In the present embodiment, the cold air passing through the refrigerator compartment 102 is blown into the vegetable compartment 103, so that cold air having a higher temperature is blown compared to the cold air blown directly from the cooler 200. However, because the cooling of the vegetable compartment 103 is performed by licking the container 410, the opening 470 provided on the right side of the lower portion of the back of the vegetable compartment 103 and the left side of the upper portion of the front portion of the vegetable compartment 103 are provided. The opening 450a is arranged in a diagonal position in the vegetable compartment, so that the cool air blown from the opening 470 provided on the right side of the lower part of the back of the vegetable compartment 103 licks the container 410 (contacts). The area becomes larger and the cooling capacity of the vegetable compartment 103 can be secured. Specifically, the cold air blows out from the opening 470 to the bottom surface of the container 410 and flows so as to lick the container 410 as shown by the dotted dotted arrows in FIG.

  As shown in FIG. 3, the opening 450 a is disposed above the front space 103 a and ahead of the front end surface of the fruit / small article container 420.

  In addition, as shown in FIG. 3, the side opening 452 of the air passage forming body 450 is provided with a preliminary opening 450b. The preliminary opening 450b is a preliminary opening when the opening 450a is closed. In addition, as shown in FIG. 4, the preliminary opening 450 b is disposed inside the vegetable compartment 103 and outside the side surface of the container 410. More specifically, the preliminary opening 450b is formed on the left side surface portion of the air passage formation body 450 when the refrigerator is viewed from the front.

  Specifically, the preliminary opening 450b is a horizontally long rectangular opening, and a plurality of preliminary openings 450b are provided in the front-rear direction on the side surface 452 of the air passage forming body 450. Note that the preliminary opening 450b may have any shape as long as it is an opening through which cold air passes, and any number may be provided.

Moreover, as shown in FIG. 4, the container 410 is provided with the insertion hole part 410a which is an insertion hole which can penetrate cold air | gas in the front wall with which a front part is equipped. The insertion hole portion 410 a is a hole through which cold air is inserted to cool a plastic bottle or the like disposed in the front portion of the container 410.

  Specifically, the insertion hole portion 410 a is a vertically long elliptical hole, and a plurality of insertion holes 410 a are provided in the lateral direction on the front wall of the container 410. The insertion hole portion 410a may have any shape as long as cold air can be inserted therethrough, and any number may be provided.

  Next, the air path forming body 450 will be described in detail.

  FIG. 6 is a perspective view of the air passage forming body of the refrigerator in the first embodiment of the present invention.

  As shown in FIG. 6, the air passage formation body 450 includes a front surface portion 451, a flat surface portion 453, a side surface portion 452, and a rear surface portion 454. The front surface portion 451 is inclined forward. As a result, a relatively hard storage item such as an apple has slightly protruded in the height direction from the fruit / small item container 420 (that is, a state in which a stored item whose height is higher than the height of the fruit / small item container 420 is inserted). Thus, even when the fruit / small container 420 moves toward the rear of the vegetable compartment 103, the fruit / small container 420 can be moved backward more smoothly than when the front portion is not inclined, such as an apple. It is possible to reduce damage to the relatively hard storage items.

  Further, as shown in FIG. 6, the air passage forming body 450 is provided with a single rib 450 c that is integrally molded with the flat surface portion 453 in the vicinity of the central portion in the width direction of the flat surface portion 453. More specifically, the rib 450c is provided in parallel with the flow direction in which the cool air returns to the cooler 200, that is, in parallel with the front-rear direction of the refrigerator. Accordingly, a relatively hard storage item such as an apple that is a storage item of the fruit / small container 420 has slightly protruded from the fruit / small object container 420 in the height direction without significantly impeding the flow of cold air (that is, In a state in which a storage item having a height higher than the height of the fruit / small container 420 is inserted, the fruit / small container 420 moves toward the rear of the vegetable compartment 103, and a relatively hard storage item such as an apple is winded. Even when the air passage formation body 450 comes into contact with the air passage formation body 450, it is difficult to deform the shape of the air passage formation body 450, and the air passage through which the cold air flows can be ensured, so that the circulation of the cold air is not hindered. That is, the rib 450c can improve the strength of the air passage formation body 450.

  Thus, in this Embodiment, the air path formation body 450 is provided in the ceiling surface (namely, lower surface of the partition plate 460) of the vegetable compartment 103, and the user has the air path formation body 450 in the vegetable compartment 103. Since it is difficult to recognize that it is provided in a state of projecting downward from the ceiling surface, it is often the case that a storage item higher than the storage height of the fruit / small article container 420 is put. Therefore, the air channel formation body 450 is such that the front surface portion 451 is inclined forward and the rib 450 c is provided on the flat surface portion 453. This embodiment is very useful.

  In the present embodiment, the rib 450c provided on the air passage forming body 453 is formed integrally with the flat surface portion 453, but may be separated from the flat surface portion 453. In this embodiment, the number of ribs 450c provided on the air passage forming body 453 is one, but it may be two or three or more.

  FIG. 5 is a diagram illustrating the flow of cold air that cools the vegetable compartment of the refrigerator according to Embodiment 1 of the present invention.

As shown in FIG. 5, the cold air generated by the cooler 200 first passes through the vegetable compartment discharge duct 480 and flows from the opening 470, and the air passage W <b> 1 behind the container 410 inside the vegetable compartment 103. Through and below the container 410. And cold air is the container 410 inside the vegetable compartment 103.
Flows from the lower rear to the front. Further, the cold air flows from the lower front side to the upper side of the container 410 inside the vegetable compartment 103. The cold air flows in this manner, thereby cooling the vegetables and plastic bottles stored in the container 410.

  And the cold air | gas which flowed above the front of this container 410 flows in into the front space 103a through the insertion hole part 410a of the container 410 front wall like the air path W1. Thereby, the inflowing cold air further cools the plastic bottle P accommodated in the front space 103a of the front portion of the container 410.

  And this cold air flows toward the opening part 450a of the air path formation body 450 arrange | positioned above the front space 103a like the air path W2. For this reason, it is difficult for this cold air to flow to the vegetables accommodated in the rear space 103b at the rear of the container 410. That is, the stored vegetables are not cooled too much.

  And cold air passes the opening part 450a like the air path W2, passes through the air path formation body 450, and returns to the cooler 200.

  Here, the refrigerator 100 may temporarily stop the flow of cold air in order to adjust the temperature in the vegetable compartment 103. That is, when the inside of the vegetable compartment 103 is cooled too much, it is possible to suppress the temperature from being excessively lowered by temporarily stopping the flow of the cold air. When the flow of cold air is temporarily stopped, the cold air may flow backward through the air passage formation body 450 as in the air passage W3.

  As described above, when the cold air flows back through the air passage formation body 450, as in the air passage W3, the opening 450a above the front space 103a passes through the opening surface 410b toward the front space 103a. Cold air flows in. For this reason, since the front space 103a is cooled by cold air, the plastic bottle P accommodated in the front space 103a in the front part of the container 410 is further cooled.

  That is, in the present embodiment, there is no cover that covers the upper part of the front space used in Patent Document 2 above the front space 103a of the container 410, and the front space 103a of the container 410 and the opening 450a. And communicate.

  In addition, the cold air flowing back from the air path forming body 450 flows toward the front space 103a in the front part of the container 410, so that the vegetables accommodated in the rear space 103b in the rear part of the container 410 are not cooled too much. .

  The fruit / small container 420 stores food such as fruit / small vegetables. Here, the opening 450 a of the air passage formation body 450 is disposed in front of the front end face of the fruit / small article container 420. For this reason, it can prevent that the opening part 450a is obstruct | occluded with the accessory vegetables etc. which are accommodated in the fruit and accessory container 420, and the circulation of cold air is inhibited.

  In addition, the side surface portion of the air passage formation body 450 is provided with a preliminary opening portion 450 b disposed inside the vegetable compartment 103 and outside the side surface of the container 410. For this reason, even when the opening part 450a of the air path formation body 450 is obstruct | occluded, it can prevent that the preliminary | backup opening part 450b is obstruct | occluded. Therefore, since the cold air with the minimum air volume can flow from the preliminary opening 450b, the circulation of the cold air is not hindered. In addition, since the preliminary opening 450b is disposed outward from the side surface of the container 410, the vegetables stored in the rear space 103b at the rear of the container 410 are not cooled excessively even when the cold air flows backward. .

  Moreover, this air path formation body 450 has the following characteristics.

  Since the air path formation body 450 is disposed immediately below the partition plate 460 that partitions the vegetable compartment 103 and the freezer compartment 104, the cold air that flows backward through the air passage formation body 450 flows into the freezer compartment 104. Under the influence, it is maintained at a low temperature, and the ability to cool the plastic bottle P accommodated in the front space 103a of the container 410 can be ensured.

  On the other hand, since the air passage formation body 450 is made of a material having thermal conductivity, such as polypropylene, which is a resin, cold air or the air blower 100a that passes through the air passage formation body 450 and returns to the cooler 200 when the blower 100a is operated. The cold air that flows back from the cooler 200 when it is stopped is radiated through the air passage formation body 450 by the radiation, the vegetables contained in the rear space 103b of the container 410, the fruits contained in the fruit / small container 420, With respect to small vegetables, predetermined cooling can be performed to such an extent that it does not cool too much without putting cold air.

  That is, the air channel formation body 450 can secure the ability to actively cool the front space 103a of the container 410 in which the plastic bottle P is accommodated by the passing cold air, while the vegetable is accommodated. The rear space 103b of the container 410 and the fruit / small container 420 in which the fruit / small vegetables are accommodated are not cooled too much without using the radiation by using the cold air that passes therethrough. In addition, predetermined cooling can be performed.

  In other words, the air path forming body 450 can simultaneously cool the cooling area (front space 103a) and mainly the freshening area (103b or 420) in the vegetable room by the cold air passing therethrough.

  In the present embodiment, the description has been given with reference to the specific form of the air passage formation body 450 as described above. However, if a conceptual configuration that exhibits the above-described effect and exhibits the effect is referred to, It becomes like this.

  That is, the front space 103a in which a plastic bottle or the like is stored in the front and the upper part is opened, the fruit / small container 420 in which the fruit and small vegetables are stored in the upper upper part, and the rear in which the vegetables and the like are stored in the lower lower part. In the vegetable room layout in which the space 103b is arranged, a radiant cooling plate that acts as a cooling source from the cooler 200 in the vicinity of the small container 420 or the opening located above the rear space 103b (in this embodiment, an air passage) By providing the forming body 450), the cool air passing through the back surface of the radiation surface of the radiation cooling plate in the path returning to the cooler 200 during the operation of the blower 100a, and the reverse flow from the cooler 200 to the vegetable compartment 103 when the blower 100a is stopped. The rear space 1 of the container 410 in which the radiant cooling plate is cooled by the cold air passing through the back surface of the radiant cooling plate in the path to be stored and the vegetables are accommodated. 3b and it can exhibit the cooling effect on fruit small container 420 fruit small vegetables is accommodated.

  In addition, the front end face of the radiant cooling plate is arranged in such a positional relationship that the back-flow cold air passes through the back surface of the radiant cooling plate and flows into the front space 103a of the container 410, and thereby the PET bottle P and the like of the front space 103a The stored item can have the effect of promoting cooling.

  As described above, by utilizing the passage of the cold air through the back surface of the radiation cooling plate while taking in the reverse flow phenomenon when the blower 100a is stopped, it is possible to provide a vegetable room cooling configuration with extremely high cooling efficiency.

In order to make good use of the reverse flow phenomenon from the cooler 200 when the blower 100a is stopped, the cooler 20 is placed above the vegetable compartment 103 as in the present embodiment.
It is easy to realize when 0 is arranged. More specifically, in the arrangement relationship in the height direction, at least a part of the cooler 200 is positioned at a height position higher than the arrangement height of the radiation surface of the radiation cooling plate (the air passage forming body 450 in the present embodiment). If the cooler 200 is arranged in this manner, the specific gravity of the cooled air, that is, the cold air becomes relatively large. Therefore, even when the blower 100a is stopped, natural air convection causes convection of the cold air, which becomes a reverse flow phenomenon and causes the radiation cooling plate to It flows into the vegetable compartment 103 through.

  And the radiation cooling plate which has a radiation surface facing the vegetable compartment 103 is arrange | positioned in the lower part of the partition plate 460 which divides the freezer compartment 104 and the vegetable compartment 103, and the radiation surface of a radiation cooling plate and the partition plate 460 are provided. The effect can be exerted if a space is formed so that cold air flows between them.

  In the present embodiment, such a configuration is presented as a specific form as the air passage formation body 450 as a so-called duct form. For this reason, in accordance with the gist of the present invention, the concept of a radiation cooling plate having a radiation surface with a changed form is an effective configuration regardless of the embodiment such as the air passage forming body 450 of the present embodiment. Is.

  As described above, according to the present invention, it is possible to cool both PET bottles that are desired to be cooled and vegetables that are desired to be excessively cooled.

  As mentioned above, although the refrigerator concerning this invention was demonstrated using the said embodiment, this invention is not limited to this.

  That is, the embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  For example, in the present embodiment, the preliminary opening portion 450 b is arranged inside the vegetable compartment 103 and outside the side surface of the container 410. However, the preliminary opening 450b may be further disposed outside the side of the fruit / small article container 420 inside the vegetable compartment 103. Thereby, obstruction | occlusion by the foodstuff of the preliminary opening part 450b can further be prevented.

  Moreover, in this Embodiment, the air path formation body 450 is arrange | positioned at the left side of the left-right direction of a refrigerator, and the dimension of the width direction of the air path formation body 450 is about 1/2 of the left-right direction of the vegetable compartment 103. However, the size in the width direction of the air channel formation body 450 is substantially the same as the width direction of the fruit / small article container 420, and the side surface of the air path formation body 450 has a downward direction. A flange may be provided to close the opening on the top surface of the fruit / small article container 420. As a result, the wind is less likely to flow into the area of the fruit / small container 420, and the food in the fruit / small container 420 can be further prevented from drying. In this case, it is desirable not to provide the opening 450a in the right half in the width direction of the air passage formation body 450 from the viewpoint of uniformly cooling the vegetable compartment.

  Further, the upper end of the fruit / small container 420 may be extended to the vicinity of the air path forming body 450 to close the opening on the upper surface of the fruit / small container 420. As a result, the wind is less likely to flow into the area of the fruit / small container 420, and the food in the fruit / small container 420 can be further prevented from drying.

(Embodiment 2)
As described above, the first embodiment has been described with respect to the air passage forming body that is arranged so as to be in contact with the partition plate and protrudes below the partition plate to form the air passage. Specifically, it is only necessary that the opening portion of the air passage formation body is provided so as to face the space in which the storage items above the front space can be stored, and the air passage formation body necessarily protrudes below the partition plate. There is no need. Therefore, the air path formation body which does not protrude below the partition plate will be described next.

  FIG. 7 is a diagram for explaining the flow of cold air for cooling the vegetable compartment of the refrigerator in the second embodiment of the present invention.

  Here, the points different from the first embodiment will be mainly described.

  As shown in FIG. 7, the air passage formation body 450 does not protrude below the partition plate 460, and is provided with a step in a part of the partition plate 460 so as to be in contact with the lower surface plate of the partition plate. An air passage forming body for forming a passage is provided. Here, the opening 450a of the air passage forming body 450 is provided facing the space 500 in which the storage items above the front space 103a can be stored.

  Specifically, the thickness of the partition plate 460 is thinner in the rear portion of the partition plate 460 (right side of the partition plate 460 in FIG. 7) than in the front portion (left side of the partition plate 460 in FIG. 7).

  More specifically, the partition plate 460 includes a heat insulating material 501 such as polystyrene foam, an upper surface plate 460a of the partition plate 460, and a lower surface plate 460b of the partition plate 460.

  Further, the upper surface plate 460a of the partition plate 460 and the lower surface plate 460b of the partition plate 460 are made of a material having thermal conductivity such as polypropylene which is a resin.

  As shown in FIG. 7, the cold air generated by the cooler 200 first passes through the vegetable compartment discharge duct 480 and flows from the opening 470, and the air passage W <b> 1 behind the container 410 inside the vegetable compartment 103. Through and below the container 410. And cold air flows in the vegetable compartment 103 inside from the lower back of the container 410 to the front. Further, the cold air flows from the lower front side to the upper side of the container 410 inside the vegetable compartment 103. The cold air flows in this manner, thereby cooling the vegetables and plastic bottles stored in the container 410.

  And the cold air | gas which flowed above the front of this container 410 flows in into the space 500 which can store the storage thing above the front space 103a like the air path W1. Thereby, the inflowing cold air further cools the plastic bottle P accommodated in the front space 103a of the front portion of the container 410.

  And this cold air flows toward the opening part 450a of the air path formation body 450 arrange | positioned above the front space 103a like the air path W2. For this reason, it is difficult for this cold air to flow to the vegetables accommodated in the rear space 103b at the rear of the container 410. That is, the stored vegetables are not cooled too much.

  And cold air passes the opening part 450a like the air path W2, passes through the air path formation body 450, and returns to the cooler 200.

Here, the refrigerator 100 may temporarily stop the flow of cold air in order to adjust the temperature in the vegetable compartment 103. That is, when the inside of the vegetable compartment 103 is cooled too much, it is possible to suppress the temperature from being excessively lowered by temporarily stopping the flow of the cold air. When the flow of cold air is temporarily stopped, the cold air may flow backward through the air passage formation body 450 as in the air passage W3.

  As described above, when the cold air flows back through the air passage formation body 450, as in the air passage W3, the opening 450a above the front space 103a passes through the opening surface 410b toward the front space 103a. Cold air flows in. For this reason, since the front space 103a is cooled by cold air, the plastic bottle P accommodated in the front space 103a in the front part of the container 410 is further cooled.

  That is, through the opening 450a, the space 500 in which the stored items can be stored and the cooler 200 are communicated with each other via the air passage forming body 450, and the cool air passes therethrough.

  In the present embodiment, the air path forming body includes an air path forming body that is arranged so as to be in contact with the lower surface plate of the partition plate and does not protrude downward from the partition plate.

  As a result, a relatively hard storage item such as an apple that is a storage item of the fruit / small container 420 is slightly protruded in the height direction from the fruit / small container 420 (that is, higher than the height of the fruit / small container 420). Even when the fruit / accessory container 420 is moved toward the rear of the vegetable compartment 103 in a state in which a large storage item is put in), since the air channel formation body 450 does not protrude below the partition plate, an apple or the like The relatively hard storage will not be damaged. Moreover, it leads to the increase in the effective internal volume of a vegetable room.

  Further, the upper surface plate 460a of the partition plate 460 and the lower surface plate 460b of the partition plate 460 are made of a material having thermal conductivity such as polypropylene as a resin, for example.

  Thereby, the cold air returning to the cooler 200 during the operation of the blower 100a through the air passage forming body 450 and the cold air flowing back from the cooler 200 when the blower 100a is stopped are passed through the lower surface plate 460b of the partition plate 460, Due to the radiation, the predetermined cooling is performed to the extent that the vegetables stored in the rear space 103b of the container 410 and the fruits / small vegetables stored in the fruit / small container 420 are not cooled too much without adding cool air. can do.

  That is, in the present embodiment, a heat insulating box made of an outer box, an inner box, a heat insulating material provided between the outer box and the inner box, and a storage chamber formed inside the heat insulating box. A refrigerating room disposed in an upper part, a freezing room disposed below the refrigerating room, a vegetable room disposed below the freezing room, a partition plate partitioning the freezing room and the vegetable room, A refrigerator that cools the air inside the heat insulating box to generate cold air, and a storage space that is provided by partitioning the vegetable compartment and has an opening surface on the upper side. The front space and the rear space disposed behind, the space formed above the opening surface of the front space, and the air flow path are formed so as to be in contact with the lower surface plate of the partition plate. An air passage forming body, and the opening of the air passage forming body is The space above the space is provided facing the space that can be stored, and through the opening, the space in which the space can be stored and the cooler are communicated via the air passage forming body. Cold air passes through it.

Thus, the opening of the air passage formation body is provided facing the space in which the stored item above the front space can be stored, and the space between the space in which the stored item can be stored and the cooler is passed through the opening. When the cool air passes through the path forming body and the cold air passes therethrough, the stored item is formed so that the cool air is formed above the opening surface of the front space when the fan is in operation. Since it returns to a cooler through the space which can be accommodated, a cooling capability can be ensured with respect to the plastic bottle accommodated in the front space.
In addition, for the rear space of the vegetable room, during operation of the blower, radiation is applied to the vegetables accommodated in the rear space through the lower surface plate of the partition plate 460 using radiation. , Can exert a cooling effect.
In addition, a relatively hard storage item such as an apple that is a storage item of the fruit / small container 420 protrudes slightly from the fruit / small container 420 in the height direction (that is, the height is higher than the height of the fruit / small container 420). Even when the fruit / accessory container 420 is moved toward the rear of the vegetable compartment 103 in a state where a high storage item is put in), the air passage forming body 450 does not protrude below the partition plate, so that the air passage is formed. It does not damage relatively hard items such as apples due to contact with the body. Moreover, it leads to the increase in the effective internal volume of a vegetable room.

  Since the present invention can cool both PET bottles to be cooled and vegetables to be prevented from being overcooled in the vegetable room, it can be cooled between various types and sizes for home use and business use. It can be used for a refrigerator of the type.
