Description

  The present invention relates to a refrigerator including an indirect cooling chamber in which a cover part and a case part are combined.

  Conventionally, refrigerators are provided with various storage rooms depending on the items to be refrigerated. For example, in addition to a refrigerated room with a door having the largest internal capacity, a vegetable room suitable for storing vegetables, a freezer room for storing frozen products, and the like are provided. In order to maintain freshness, a low-pressure chamber that places the chamber in a low oxygen state may be provided in the storage chamber (refrigerated chamber). The air in the low pressure chamber is exhausted by a vacuum pump or the like, and the pressure in the low pressure chamber is lowered.

  An example of a refrigerator provided with such a low-pressure chamber is described in Patent Document 1. Specifically, Patent Document 1 includes a refrigerating chamber provided with a door, a low-pressure chamber in the refrigerating chamber, and a decompression means for depressurizing the low-pressure chamber, and the low-pressure chamber has an opening for taking in and out stored items. A chamber body, a low-pressure chamber door that opens and closes the food in / out opening, and pressure detection means for determining whether the low-pressure chamber is higher or lower than a predetermined pressure. There is described a refrigerator that stops the decompression means when a second predetermined time has elapsed after the means detects that the pressure is lower than the predetermined pressure. With this configuration, the pressure detection means uses, for example, a pressure detection switch, so that it is not necessary to use a pressure sensor, so that it is not necessary to use an expensive pressure sensor.

Japanese Patent No. 4940046

  Conventionally, for example, in a main refrigeration room (storage room) provided above a refrigerator and having the largest internal capacity, a storage room (section) for cooling food at a temperature lower than the temperature in the refrigeration room may be provided. is there. Such a storage room (section) is referred to as a “chilled room”, for example. For example, a storage room that is kept at a lower temperature (for example, around 0 ° C.) than the refrigeration room, while the temperature of the refrigeration room is (about 3 to 5 ° C.) conventionally, is provided in the refrigeration room. There is. Such a storage room (section) is referred to as a “chilled room”, for example. A temperature range of about 0 ° C. is suitable for storing meat, fish, dairy products, kneaded products, pickles and the like.

  It is necessary to actively cool the chilled room in order to lower the temperature than the other parts of the refrigerator room. Therefore, conventionally, in order to lower the temperature of the chilled chamber, cold air is blown out toward the chilled chamber, or a gap is provided in the chilled chamber to increase the amount of cold air flowing into the chilled chamber.

  However, since the dry cold air flows into the chilled chamber, there is a problem that the moisture in the food in the chilled chamber is easily lost (the food is easily dried). If the amount of water evaporation is large, the flavor and appearance of the food may be impaired.

  Here, in the low-pressure chamber as described in Patent Document 1, since the pressure is reduced while being sealed, there is an advantage that moisture hardly escapes from the low-pressure chamber and drying is easily prevented. However, in exchange for reducing the pressure, there is a problem that the structure of the low-pressure chamber itself and the structure in the vicinity of the low-pressure chamber must be strong enough to withstand the pressure reduction (solid structure) as compared with the case where pressure is not reduced. . Further, since the structure of the low-pressure chamber is strengthened, there is a problem that the internal volume of the low-pressure chamber is reduced as compared with a structure where pressure is not reduced.

  In view of the above-described problems, the present invention realizes providing an indirect cooling chamber that easily maintains a high hermeticity and hardly causes drying of food without giving a complicated structure to the storage chamber.

  In order to achieve the above object, the refrigerator according to claim 1 is movable in the front-rear direction, and includes a cooling unit that generates cold air and sends out the cold air, and a storage room that includes a blowout port that blows out the cold air generated by the cooling unit. A case portion that accommodates a stored item, and a cover portion that is provided above the case portion and covers the case portion when the case portion is in a retracted state, and is provided in the storage chamber. A refrigerator comprising: an indirect cooling chamber in which a room is indirectly cooled by cold air around the cover portion; and a holding portion that holds the case portion in a retracted state.

  According to this configuration, the indirect cooling chamber is configured by the case portion and the cover portion that is provided below the partition shelf and above the case portion and covers the case portion when the case portion is stored. And a holding portion that holds the case portion pushed in and in a retracted state.

  Thereby, since the case part can be held by the holding part, it is possible to prevent the case part in the retracted state from moving and the gap between the case part and the cover part from becoming large. Therefore, the indirect cooling chamber can be kept in a highly airtight state, and the food can be prevented from drying. Moreover, the indirect cooling chamber which has high sealing performance and hardly causes drying of food can be provided simply by placing the case portion in the retracted state and covering the case portion with the cover portion. And compared with the case where decompression is accompanied like a low-pressure chamber, without using a strong member and a reinforcement member, the sealing property of an indirect cooling chamber can be improved easily and entry of cold air can be reduced.

  In the refrigerator having the above-described configuration, a protrusion is provided on the lower surface of the case portion, and the holding portion is pressed by the protrusion when the case portion is in a retracted state to be deformed, and a spring that presses the protrusion. May be included.

  With this configuration, it is possible to securely hold the case portion that is in a stored state with a simple configuration. Further, since the holding is performed on the lower surface of the case portion that is difficult for the user to visually recognize, it is also preferable from the viewpoint of aesthetics.

  In the refrigerator having the above-described configuration, the spring portion includes a first inclined portion that comes into contact with the protruding portion, and the first inclined portion has a force that the spring portion presses the protruding portion as the case portion is pressed. You may incline so that it may become weak.

  With this configuration, it is possible to generate a force in a direction in which the case portion is pushed toward the retracted state (a force that guides the case portion to the back side). In other words, it is possible to firmly hold the case portion in the retracted state by giving the spring portion a force for moving the case portion to the back side, which is the direction in which the spring portion is stabilized. Thereby, the case part can be maintained in a stable state (stored state) so that no gap is generated between the case part and the cover part.

  In the refrigerator configured as described above, the spring portion may have a second inclined portion that first contacts the protrusion when the case portion is pushed.

  With this configuration, even if the case portion is moved in the direction in which the case portion is retracted vigorously, the force of the projection portion colliding with the spring portion can be released by the inclination. Therefore, the impact on the protrusion and the spring can be reduced, and the damage on the protrusion and the spring can be eliminated.

  Further, in the refrigerator having the above-described configuration, the protruding portion is a central portion in the left-right direction of the case portion, and is provided near the back surface of the case portion, and the holding portion is in the retracted state of the case portion. Depending on the position of the protrusion, the protrusion may be provided at a position where the protrusion is pressed.

  With this configuration, since the protruding portion and the holding portion are provided at the central portion in the left-right direction, the case portion can be appropriately held at a position close to the center of the case portion. Further, since the protrusion and the holding part are provided at the position on the back side of the case part, it is difficult for the user to visually recognize and is preferable from the viewpoint of aesthetics.

  Further, in the refrigerator having the above-described configuration, the protruding portion is a central portion in the left-right direction of the case portion, and is provided near the front of the case portion, and the holding portion is in the retracted state of the case portion. Depending on the position of the protrusion, the protrusion may be provided at a position where the protrusion is pressed.

  With this configuration, since the protruding portion and the holding portion are provided at the central portion in the left-right direction, the case portion can be appropriately held at a position close to the center of the case portion. In addition, since the protrusion and the holding part are provided near the front of the case part, it is easy to grasp whether or not the user has held it, and there is a large gap between the case part and the cover part (the case part is properly It is not maintained in the state of not storing.

  In the refrigerator having the above-described configuration, a seal member for closing a gap between the case portion and the cover portion may be provided on one of the case portion and the cover portion.

  With this configuration, the hermeticity of the indirect cooling chamber (the hermeticity when the cover part and the case part are overlapped) can be enhanced. Accordingly, it is possible to make it difficult to dry the food.

  According to the refrigerator of the present invention, it is possible to provide a refrigerator provided with an indirect cooling chamber that is inexpensive, easily sealed, and difficult to dry ingredients without giving a complicated structure to the storage chamber. In addition, since the case portion can be held by the holding portion, the case portion in the retracted state can be prevented from moving, and the gap between the case portion and the cover portion can be prevented from becoming large.

In addition, a second ventilation path 74 connected to the first ventilation path 73 is provided behind the refrigerator compartment 2. The generated cool air is supplied to each chamber through the first ventilation path 73 and the second ventilation path 74.

  A first blower 75 is disposed in the first ventilation path 73. The cold air generated by the cooler 71 is sent out by the first blower 75. For example, the cold air sent out by the first blower 75 is supplied to the ice making room 3, the upper freezer room 4, and the lower freezer room 5 through the first ventilation path 73.

  The first ventilation path 73 is connected to an ice making chamber outlet 81 provided on the back surface of the ice making chamber 3 and an upper freezer compartment outlet 82 (see FIG. 3). The cold air generated by the cooler 71 is sent up to the ice making chamber 3 by raising the first ventilation path 73 as shown by an arrow A (see FIG. 3) by driving the first blower 75. Further, the cold air generated by the cooler 71 rises through the first ventilation path 73 as shown by an arrow B (see FIG. 3) by driving the first blower 75 and is sent out to the upper freezer compartment 4. Thereby, the ice making room 3 and the upper freezer room 4 are cooled.

  Then, a lower freezing room 5 is connected to the ice making room 3 and the upper freezing room 4. The cold air that has passed through the ice making chamber 3 and the upper freezing chamber 4 also flows into the lower freezing chamber 5. Thereby, in addition to the ice making chamber 3 and the upper freezer compartment 4, the lower freezer compartment 5 is also cooled. A return ventilation path 76 (see FIG. 2) is provided in the lower rear part of the lower freezer compartment 5 to guide the air and return the cool air to the cooler 71 of the first ventilation path 73. Then, the cool air returns to the cooler 71 through the return ventilation path 76.

  A second blower 77 is disposed in the second ventilation path 74. The cold air generated by the cooler 71 is also sent out by the second blower 77. For example, the cold air sent out by the second blower 77 is supplied to the refrigerator compartment 2, the chilled compartment 1, and the vegetable compartment 6 through the second ventilation path 74.

  The upper part of the first ventilation path 73 is connected to the second ventilation path 74. A cold room damper 78 is provided between the first ventilation path 73 and the second ventilation path 74. The cold air branched in the direction of the second ventilation path 74 in the upper part of the first ventilation path 73 passes through the second ventilation path 74 as shown by an arrow C (see FIG. 3) through the refrigerator compartment damper 78 by driving the second blower 77. Flowing. The second ventilation path 74 is connected to a plurality of refrigerating room outlets 83 on the back side of the refrigerating room 2. Thereby, the cold air flowing through the second ventilation path 74 is blown into the refrigerator compartment 2.

  Further, the second ventilation path 74 is connected to an outlet 80 provided on the back side of the chilled chamber 1. Thereby, the cold air flowing through the second ventilation path 74 is also blown out from the rear of the chilled chamber 1 as indicated by an arrow D (see FIG. 3).

  A return port 84 is provided at the lower back of the refrigerator compartment 2 to collect the cold air below the refrigerator compartment 2 and send it out toward the vegetable compartment 6. The return port 84 is connected to the vegetable compartment 6 by a vegetable compartment ventilation path 79 (see FIG. 3). Thus, the cold air led to the second ventilation path 74 flows into the vegetable compartment 6 after passing through the refrigerator compartment 2 and the chilled compartment 1. The cold air that has flowed into the vegetable compartment 6 flows through the vegetable compartment 6 and returns to the cooler 71 via the ventilation path 76. When the refrigerator compartment 2, the chilled compartment 1, and the vegetable compartment 6 are cooled and reach a set temperature, the refrigerator compartment damper 78 is closed.

  In the refrigerator 100 of the embodiment, the ice making room 3, the upper freezer room 4, and the refrigerating room 2 are arranged in parallel in a cold air circuit (see FIG. 4).

A handle portion 13 for hooking a finger is provided below the front portion of the case portion 11 for inserting and removing the case portion 11.

  And the case part 11 is made into a retracted state so that the clearance gap between the lower end part of the cover part 12 and the upper end part of the case part 11 may be lose | eliminated. Therefore, the size seen from the up-down direction of the lower end edge part of the cover part 12 and the upper end edge part of the case part 11 is made the same.

  Specifically, as shown in FIGS. 5 and 6, when the case unit 11 is in the retracted state, the cover unit 12 prevents the inflow and outflow of cold air between the case unit 11 and the cover unit 12. Cover. More specifically, the length of the side of the lower end edge portion 12F of the front portion (front portion) of the cover portion 12 is equal to the length of the side of the upper end edge portion 11F of the front portion (front portion) of the case portion 11, or Is almost equal. Further, the length of the side of the lower end edge portion 12B of the back surface portion (rear portion) of the cover portion 12 and the length of the side of the upper end edge portion 11B of the back surface portion (rear portion) of the case portion 11 are equal or substantially equal. . Further, the lengths of the sides of the lower edge portions 12R and 12L of the left and right side portions (left and right portions) of the cover portion 12 and the lengths of the sides of the upper edge portions 11R and 11L of the left and right side portions (left and right portions) of the case portion 11 are also shown. The lengths are equal or nearly equal.

  In the case portion 11, the case portion side facing portion (upper edge portions 11 </ b> R and 11 </ b> L in the present embodiment) facing the cover portion 12 in the left-right direction of the case portion 11, and the cover portion 12 among the cover portion 12. The case portion 11 is stored such that there is no gap between the cover portion side facing portions (in this embodiment, the lower edge portions 12R and 12L) facing the case portion 11 in the left-right direction. Further, in the case portion 11, the case portion side facing portion (the upper end edge portion 11 </ b> F in the present embodiment) facing the cover portion 12 on the front side of the case portion 11, and the cover portion 12, the front side of the cover portion 12. Thus, the case part 11 is stored so that there is no gap between the cover part side facing part (in this embodiment, the lower end edge part 12F) facing the case part 11. Further, in the case portion 11, the case portion side facing portion (the upper end edge portion 11 </ b> B in this embodiment) facing the cover portion 12 on the back side of the case portion 11, and the cover portion 12, the back side of the cover portion 12. Thus, the case portion 11 is stored such that there is no gap between the cover portion side facing portion (in this embodiment, the lower end edge portion 12B) facing the case portion 11.

  In addition, when the case part 11 is set in the retracted state, a seal member 14 is provided so that there is no gap between the cover part 12 and the case part 11 (details will be described later).

  Further, the cover portion 12 is attached to the partition shelf 24. Therefore, in the refrigerator compartment 2, the cover part 12 will be in the state hung by the partition shelf 24. FIG. For example, a plurality of engaging claws (not shown) for fitting are provided on either the upper surface of the cover portion 12 or the lower side of the partition shelf 24. And the engaging part (not shown) in which an engaging claw is engage | inserted is provided in either other. Thereby, the cover part 12 is fixed and supported so that the cover part 12 is positioned at a fixed position with respect to the partition shelf 24, the refrigerator compartment 2, and the case part 11.

(Indirect cooling of chilled chamber 1)
Next, details of indirect cooling of the chilled chamber 1 will be described with reference to FIGS. 7 and 8. FIG. 7 is an explanatory view showing an example of a wall surface portion 2 b of the refrigerator compartment 2 on the back side of the chilled chamber 1. FIG. 8 is a schematic right side sectional view of the chilled chamber 1 portion.

  As shown in FIG. 7, an outlet 80 (which can be said to be a kind of the refrigerator compartment outlet 83) is provided in the wall surface portion 2 b on the inner side of the refrigerator compartment 2 on the inner side of the chilled chamber 1. The width of the blower outlet 80 in the left-right direction can be determined as appropriate (for example, about one-tenth to one-tenth of the lateral width of the chilled chamber 1). Further, the number of outlets 80 is not limited to one, and two or more outlets 80 may be provided while providing an interval.

  In addition, a return port 84 is provided on the right side of the air outlet 80 in the wall surface portion 2 b of the refrigerator compartment 2 on the back side of the chilled chamber 1. As shown in FIG. 7, the return port 84 can be provided with a fan 85 that sends out the cold air in the refrigerator compartment 2 toward the vegetable compartment 6, the cooler 71, and the like.

  And as shown in FIG. 8, the blower outlet 80 provided in the back side of the chilled chamber 1 blows cold air toward the back surface of the cover part 12 (chilled chamber 1). This cold air indirectly cools the chilled chamber 1. Since the cold air gathers at the return port 84, the cold air blown from the plurality of cold room outlets 83 to the cold room 2 above the chilled room 1 also descends around the chilled room 1, Cool indirectly.

  As shown in FIG. 8, it is provided between the partition shelf 24 and the cover portion 12, is in contact with the upper surface of the cover portion 12 (using the upper surface of the cover portion 12 as the wall surface of the passage), and cool air from the outlet 80. Is provided from the back side to the front side of the chilled chamber 1. In addition, in FIG. 8, the flow of the cold air which blows off from the blower outlet 80 and is transmitted through the 1st channel | path 15 is illustrated with a white arrow.

  Specifically, a space between the partition shelf 24 and the upper surface of the cover portion 12 is used as the first passage 15. As a result, the first passage 15 is formed over (substantially) the entire top surface of the cover portion 12. In other words, a flat portion of the upper surface of the cover portion 12 is used as the first passage 15. Thereby, the upper surface of the cover part 12 contacts the cold as a whole. Therefore, the chilled chamber 1 can be efficiently cooled.

  Here, as shown in FIG. 8, the cold air sent to the front side of the chilled chamber 1 while in contact with the upper surface of the cover portion 12 flows downward from the side surface of the chilled chamber 1. In other words, the first passage 15 causes the cold air flowing into the first passage 15 to flow to the side surface of the chilled chamber 1.

  Specifically, a guide wall 16 is provided at the edge portion of the upper surface of the cover portion 12 for flowing the cold air flowing into the first passage 15 to the side surface of the chilled chamber 1 (see FIG. 6). The guide wall 16 is provided on the left and right edge portions of the upper surface of the cover portion 12. The guide wall 16 extends from the upper surface of the cover portion 12 toward the partition shelf 24 and is in contact with the partition shelf 24 or a gap is provided between the guide wall 16 and the partition shelf 24.

  The guide wall 16 is erected between the left and right edge portions of the upper surface of the cover portion 12 from the back surface to the end point position 16a provided on the front side rather than the center position in the front-rear direction. Thereby, after a certain amount of cold air is sent to the front (front side) of the chilled chamber 1 (cover portion 12), the left and right side surfaces of the chilled chamber 1 (right side direction of the refrigerator compartment 2 and the egg case 26 and the chilled chamber 1). Between). As described above, since the area where the cold air is in contact with the chilled chamber 1 is obtained, the interior of the chilled chamber 1 can be sufficiently cooled even by indirect cooling.

  Further, as shown in FIG. 8, it is provided between the lower surface (bottom surface 2 a) of the refrigerator compartment 2 and the case portion 11 (provided below the case portion 11), and is in contact with the lower surface of the case portion 11 (case portion 11). ), And a second passage 17 through which cool air passes from the front side of the chilled chamber 1 toward the return port 84. In FIG. 8, the flow of cold air from the entire surface side of the chilled chamber 1 toward the return port 84 is indicated by a shaded arrow.

  Specifically, a space between the lower surface (bottom surface 2 a) of the refrigerator compartment 2 and the case portion 11 is used as the second passage 17. Thereby, the second passage 17 is formed on the lower surface of the case portion 11. In other words, a flat portion of the case portion 11 is used as the second passage 17. Thereby, the lower surface of the case part 11 can also be made to contact cold air. Therefore, the chilled chamber 1 can be efficiently cooled.

  In addition, in order to mount the case part 11 while providing the 2nd channel | path 17, a part of bottom face 2a of the refrigerator compartment 2 is good also as a raised shape. The case portion 11 is placed on the raised portion, and the case portion 11 can be stored in a stable state.

  Further, the air outlet 80 is provided on the back side of the chilled chamber 1 and above the return port 84. Further, the air outlet 80 is provided to the left of the center of the chilled chamber 1, and the return port 84 is provided on the right side of the center of the chilled chamber 1. Thereby, the cold air blown out from the outlet 80 can flow on the upper surface of the cover portion 12 in an oblique direction with respect to the direction in which the case portion 11 is put in and out (front-rear direction). In other words, it is possible to flow cool air while gaining a surface area in contact with the cover portion 12, and the chilled chamber 1 can be indirectly cooled efficiently.

  When the air outlet 80 is provided on the right side of the center, the return port 84 may be provided on the left side of the center of the chilled chamber 1.

(Seal member 14)
Next, the sealing member 14 that closes the gap between the cover portion 12 and the case portion 11 of the chilled chamber 1 according to the embodiment will be described with reference to FIGS. FIG. 9A is an explanatory diagram for explaining an example of the sealing member 14R that closes the gap between the cover portion 12 and the right side surface portion of the case portion 11 corresponding to the position of the portion A surrounded by the broken line in FIG. FIG. 8B is an enlarged view of the portion surrounded by the broken line A in FIG. 8 as viewed from the front, and is an explanatory diagram for explaining an example of the sealing member 14L that closes the gap between the cover portion 12 and the left side portion of the case portion 11. It is. FIG. 10 is an enlarged view of a portion B surrounded by a broken line in FIG. 8, and is an explanatory diagram for explaining an example of a seal member 14 </ b> F that closes a gap between the cover portion 12 and the front portion of the case portion 11. FIG. 11 is an enlarged view of a portion C surrounded by a broken line in FIG. 8, and is an explanatory diagram for explaining an example of a seal member 14B that closes a gap between the cover portion 12 and the rear portion of the case portion 11.

<Sealing of gaps at the left and right sides of the chilled chamber 1>
First, the sealing of the gap between the cover portion 12 and the case portion 11 at the left and right side portions of the chilled chamber 1 of the present embodiment will be described with reference to FIGS.

  First, as shown in FIG. 9A and FIG. 9B, the chilled chamber 1 of the present embodiment has a lower end edge portion 12R, 12L (cover portion side facing portion) in the left-right direction of the cover portion 12. Attached as a part of the cover part 12, between the upper edge 11R, 11L (case part side facing part) in the left-right direction of the case part 11 and the lower edge 12R, 12L in the left-right direction of the cover part 12 Seal members 14R and 14L that close the gap are provided. The seal members 14 </ b> R and 14 </ b> L are packings that prevent inflow and outflow of air into the chilled chamber 1.

  The seal members 14R and 14L have a U-shape (concave shape), and the recessed portions are fitted into the lower end edges 12R and 12L (cover portion side facing portions) of the cover portion 12. Thus, the seal members 14R and 14L are attached to the cover part 12 as a part of the cover part 12.

  The seal members 14R and 14L may be attached to the upper edge portions 11R and 11L (case portion side facing portions) in the left-right direction of the case portion 11 as a part of the case portion 11 (the seal members 14R and 14L are You may attach to the case part 11 side). In addition, in FIG. 10 (a), (b), an example at the time of providing the sealing members 14R and 14L in the case part 11 side is illustrated with the broken line.

  When the case portion 11 is in the retracted state (when the cover portion 12 is in a state of covering the case portion 11) with these seal members 14R and 14L, the air into the chilled chamber 1 at the side surface portion of the chilled chamber 1 Inflow and outflow of air from the chilled chamber 1 are prevented. Therefore, the hermeticity of the chilled chamber 1 can be improved.

  Here, upper end edges 11R and 11L (case portion side facing portions) in the left-right direction of the case portion 11 are inclined (inclined shape) so as to be higher on the front side and lower on the back side. . Corresponding to the inclination of the upper edge portions 11R, 11L of the case portion 11, the lower edge portions 12R, 12L (cover portion side facing portions) in the left-right direction of the cover portion 12 are slanted so as to become lower toward the back side. It is slanted so as to be higher toward the side (inclined shape).

  The angle of inclination can be determined as appropriate. In the refrigerator 100 of the present embodiment, the inclination angle is not caught by the cover part 12 when the case part 11 is pulled out, and in order to secure a sufficient storage amount, an angle of about 5 to 15 degrees with respect to the horizontal plane. Is done. More preferably, the inclination is about 7 to 9 degrees with respect to the horizontal plane.

  Thereby, the state where the seal members 14R and 14L and the upper end edge portions 11R and 11L of the case portion 11 are rubbed does not continue, and the case portion 11 can be smoothly pulled out with a light force. Further, the state in which the seal members 14R, 14L and the upper end edges 11R, 11L of the case part 11 are rubbed does not continue, and the case part 11 can be smoothly returned to the retracted state with a light force. Further, it is difficult to deteriorate due to the friction of the seal members 14R and 14L. Further, the seal members 14R and 14L are not detached from the lower end edges 12R and 12L of the cover portion 12 due to friction.

<Seal for gaps in front of chilled chamber 1>
Next, the sealing of the gap between the cover portion 12 and the case portion 11 at the front portion of the chilled chamber 1 of the present embodiment will be described with reference to FIG.

  First, as shown in FIG. 10, the chilled chamber 1 of the present embodiment is attached as a part of the cover part 12 to the upper part on the front side of the cover part 12 (cover part side facing part), and the front of the case part 11. A seal member 14 </ b> F is provided to close a gap between the upper side portion (case portion side facing portion) and the front side upper portion of the cover portion 12. Specifically, the seal member 14 </ b> F is attached to the front side lower end edge portion 12 </ b> F of the cover portion 12 as a part of the cover portion 12. The seal member 14 </ b> F is also a packing that prevents air from flowing into and out of the chilled chamber 1.

  The seal member 14 </ b> F has a U-shape (concave shape), and the recessed portion is fitted into the upper portion on the front side of the cover portion 12 (front side lower end edge portion 12 </ b> F, cover portion side facing portion). Thereby, the seal member 14 </ b> F is attached to the cover part 12 as a part of the cover part 12.

  The seal member 14F may be attached as a part of the case portion 11 to the upper portion on the front side of the case portion 11 (the front side upper edge portion 11F of the case portion 11 and the case portion side facing portion) (the seal member 14F). May be attached to the case 11 side). In addition, in FIG. 11, an example at the time of providing the sealing member 14F in the case part 11 side is illustrated with the broken line.

  When the case portion 11 is in the retracted state by the seal member 14F (when the cover portion 12 covers the case portion 11), the air into the chilled chamber 1 at the front portion (front portion) of the chilled chamber 1 Inflow and air outflow from the chilled chamber 1 are prevented. Therefore, the hermeticity of the chilled chamber 1 can be improved.

  Here, the front side upper portion (upper edge portion 11F, case portion side facing portion) of the case portion 11 is in contact with the seal member 14F in the front-rear direction. The shape of the cover part 12 may also bend (a part of the cover part 12 swells downward) due to the influence of the deflection of the partition shelf 24 (the load related to the partition shelf). However, the front side upper part (upper end edge part 11F) of the case part 11 and the front side upper part (lower end edge part 12F) of the cover part 12 are in contact in the front-rear direction via the seal member 14F. The force required for taking in and out is almost the same regardless of the deformation of the shape of the cover portion 12.

<Seal of gap at the back of chilled chamber 1>
Next, with reference to FIGS. 9 and 11, the seal of the gap between the cover portion 12 and the case portion 11 at the back surface portion of the chilled chamber 1 of the present embodiment will be described.

  First, as shown in FIG. 11, the chilled chamber 1 according to the present embodiment is attached as a part of the cover portion 12 to the back side lower end edge portion 12 </ b> B (cover portion side facing portion) of the cover portion 12. A seal member 14B is provided to close a gap between the upper end edge portion 11B (case portion side facing portion) on the back side and the back side lower end edge portion 12B of the cover portion 12. Specifically, the seal member 14 </ b> B is attached to the back side lower edge 12 </ b> B of the cover part 12 as a part of the cover part 12. The seal member 14 </ b> B is also a packing that prevents the inflow and outflow of air into the chilled chamber 1.

  The seal member 14 </ b> B has a U-shape (concave shape), and a recessed portion is fitted into the back side lower end edge portion 12 </ b> B of the cover portion 12. Thereby, the seal member 14 </ b> B is attached to the cover part 12 as a part of the cover part 12.

  The seal member 14B may be attached as a part of the case portion 11 to the upper back edge 11B (case portion side facing portion) of the case portion 11 (the seal member 14B may be attached to the case portion 11 side). ). In addition, in FIG. 11, an example at the time of providing the sealing member 14B in the case part 11 side is illustrated with the broken line.

  When the case portion 11 is in the retracted state by the seal member 14B (when the case portion 11 is covered with the cover portion 12), the air into the chilled chamber 1 at the rear portion (rear portion) of the chilled chamber 1 Inflow and air outflow from the chilled chamber 1 are prevented. Therefore, the hermeticity of the chilled chamber 1 can be improved.

  Here, the upper end edge portion 11B of the case portion 11 is in contact with the seal member 14B in the front-rear direction. The shape of the cover part 12 may also bend (a part of the cover part 12 swells downward) due to the influence of the deflection of the partition shelf 24 (the load related to the partition shelf). However, since the upper end edge portion 11B of the case portion 11 and the lower end edge portion 12B of the cover portion 12 are in contact with each other in the front-rear direction via the seal member 14B, the force required for the case portion 11 to be taken in and out is the shape of the cover portion 12. There is almost no change regardless of deflection.

(Holding the case 11 in the stored state)
Next, an example of holding | maintenance (maintenance of sealing property) of the case part 11 of the storage state in the chilled chamber 1 which concerns on embodiment is demonstrated using FIGS. FIG. 12 is a perspective view of the chilled chamber 1 as viewed from the lower right side. FIG. 13 is a bottom view of the state in which the holding part 9 holds the case part 11 as viewed from below. FIG. 14 is an explanatory diagram illustrating an example of the holding unit 9. FIG. 15 is an explanatory view showing an example of a modified example in which the arrangement positions of the protruding portion 110 and the holding portion 9 are changed.

  As described above, the cover portion 12 covers the case portion 11 so that there is no gap between the cover portion 12 and the case portion 11 when the case portion 11 is in the retracted state. In other words, when the case unit 11 is in the retracted state, the chilled chamber 1 is in a state of high sealing performance.

  However, if the case portion 11 swings and the position of the case portion 11 is easily displaced when the case portion 11 is in the retracted state, a gap is formed between the cover portion 12 and the case portion 11. If it does so, the water | moisture content (water vapor | steam) in the chilled chamber 1 will escape from the clearance gap, and drying of the stored matter (foodstuff) in the chilled chamber 1 will advance.

  Therefore, the refrigerator 1 of the present embodiment is provided with a holding unit 9 that holds the case unit 11 in the stored state. The holding part 9 is pushed in to hold the case part 11 in the retracted state so that a large gap is not formed between the case part 11 and the cover part 12. Further, holding the case portion 11 by the holding portion 9 means that the case portion 11 is fixed at a fixed position when the case portion 11 is in the retracted state. Therefore, the cover portion 12 can be covered (covered) on the case portion 11 so as not to cause a gap.

  As shown in FIGS. 12 and 13, the holding portion 9 is provided on the lower surface than the case portion 11. And the holding | maintenance part 9 is attached to the bottom face 2a of the refrigerator compartment 2. FIG.

  In order to hold the case 11 in the retracted state at a fixed position (predetermined position), as shown in FIG. 13, two protrusions 110 are provided on the lower surface of the case 11. Two protrusions 110 are provided in the case portion 11 of the present embodiment. The two projecting portions 110 are provided side by side with a predetermined interval in a direction parallel to the left-right direction of the case portion 11. In this embodiment, an example in which two protrusions 110 are provided will be described, but three or more protrusions 110 may be provided.

  Each protrusion 110 has a cylindrical shape. Each protrusion 110 is formed integrally with the case 11 (may be attached). Therefore, two protrusions protrude from the lower surface of the case portion 11 of the present embodiment.

  A holding portion 9 provided below the case portion 11 and on the bottom surface 2a of the refrigerator compartment 2 includes a fixing portion 9a for fixing the holding portion 9 to the bottom surface 2a of the refrigerator compartment 2, and a case from the fixing portion 9a. A spring portion 90 extending in the direction in which the portion 11 is taken in and out (the front-back direction of the chilled chamber 1) is included. The holding portion 9 is provided with two spring portions 90. As shown in FIGS. 13 and 14, the spring portion 90 of each holding portion 9 is a leaf spring. Each spring part 90 may be made of resin or metal.

  Each spring portion 90 extends in a direction parallel to the direction in which the case portion 11 is taken in and out. Then, when the case portion 11 is in the retracted state, each spring portion 90 is pressed by the protrusion 110 to be deformed, and is pressed so as to sandwich the protrusion 110. Since the two spring portions 90 sandwich the protruding portion 110, the interval between the spring portions 90 is wider than the interval between the two protruding portions 110.

  Each spring part 90 has a first inclined part 91 in contact with the protruding part 110. The first inclined portion 91 may be formed by bending the front side of each spring portion 90 inward (in the direction between the two spring portions 90) in the middle. Moreover, the 1st inclination part 91 may be provided in each spring part 90 by sticking members, such as resin, to a leaf | plate spring.

  As shown in FIGS. 13 and 14, the first inclined portion 91 is spaced from each of the first inclined portions 91 of the spring portions 90 facing each other toward the front side of the case portion 11 (chilled chamber 1) when viewed from the vertical direction. Is inclined to become narrower. In other words, the first inclined portion of each spring portion 90 when viewed from below the case portion 11 with the front side (front side) of the case portion 11 (chilled chamber 1) as the upper side and the front side (front side) as the lower side. 91 inclines in a letter C shape (downwardly obliquely).

  Since the first inclined portion 91 has such an inclination, the force by which the spring portion 90 presses the projection 110 as the case portion 11 is pushed in (as it is put into the retracted state) (based on the elasticity of the spring portion 90). The power to return) is weakened. In addition, the cylindrical protrusion 110 is in contact with the first inclined portion 91 so as to slide. Thereby, the force of the spring part 90 can be exerted in the direction in which the case part 11 is directed toward the back (the direction in which the case part 11 is pulled back).

  Specifically, as shown in FIG. 13, when the case portion 11 is in the retracted state, each spring portion 90 of the holding portion 9 is pushed and deformed by the protruding portion 110 and holds the protruding portion 110. However, the first inclined portion 91 is inclined so that the force with which the spring portion 90 presses the protruding portion 110 becomes weaker as the case portion 11 is pushed. Therefore, when moving the case part 11 in the retracted state (the case part 11 held by the holding part 9), it is necessary to pull out the case part 11 beyond the force that pulls the case part 11 back. Therefore, when the case part 11 is in the retracted state, the case part 11 is stable in the pushed-in state (stored state), the case part 11 does not wobble, and there is no gap between the case part 11 and the cover part 12 The case portion 11 is held so that

  Therefore, when the case portion 11 is in the retracted state, the holding portion 9 is attached at a position where the first inclined portion 91 of each spring portion 90 and the protruding portion 110 are in contact with each other.

  Each spring portion 90 has a second inclined portion 92 that first comes into contact with the protruding portion 110 when the case portion 11 is pushed into the front side (front side) of the case portion 11 with respect to the first inclined portion 91. In other words, the second inclined portion 92 is provided at the front end portion of each spring portion 90 on the front side of the case portion 11 (the first inclined portion 91 is located on the back side of the second inclined portion 92).

  As shown in FIG. 13 and FIG. 14, the second inclined portion 92 has a larger interval between the second inclined portions 92 of the spring portions 90 facing each other as viewed from the vertical direction as the front side of the case portion 11 (chilled chamber 1). It is inclined to become. In other words, the first inclined portion of each spring portion 90 when viewed from below the case portion 11 with the front side (front side) of the case portion 11 (chilled chamber 1) as the upper side and the front side (front side) as the lower side. 91 is inclined in an inverted C shape (upwardly obliquely).

  Due to the second inclined portion 92, the cylindrical protrusion 110 slides on the second inclined portion 92 when the protruding portion 110 hits the spring portion 90 (holding portion 9). Therefore, when the case part 11 is accommodated (when it is pushed back), the projecting part 110 does not collide with each spring part 90 and the projecting part 110 is not broken or cracked at the base. The case portion 11 can be smoothly put in and out by the first inclined portion 91 and the second inclined portion 92.

  And as shown in FIG. 13, each protrusion part 110 is a center part in the left-right direction of the case part 11, Comprising: It is provided in the back side of the case part 11 (center part back of the case part 11). On the other hand, the holding part 9 is provided at a position where the first inclined part 91 of each spring part 90 presses each projection part 110 according to the position of each projection part 110 when the case part 11 is stored. Thereby, the holding | maintenance part 9 will be provided in the back | inner side of the refrigerator compartment 2, and the holding | maintenance part 9 is distribute | arranged to the position where it is hard to see from a user.

  FIG. 15 shows a modification in which the arrangement positions of the protrusion 110 and the holding unit 9 are changed from the example of FIG. FIG. 15 is a bottom view of the state in which the holding unit 9 in the modified example holds the case unit 11 as viewed from below.

  Specifically, as shown in FIG. 15, each protrusion 110 is a central portion in the left-right direction of the case portion 11, and may be provided near the front of the case portion 11 (in front of the central portion of the case portion 11). . On the other hand, the holding portion 9 may be provided at a position where the first inclined portion 91 of each spring portion 90 presses each protrusion 110 according to the position of each protrusion 110 when the case portion 11 is in the retracted state. Accordingly, the holding portion 9 is provided on the near side of the refrigerator compartment 2, and the case portion 11 can be firmly held on the near side of the case portion 11.

  In this way, the refrigerator 1 according to the embodiment generates cool air and cools the cool air (the cooler 71, the compressor 72, the first ventilation path 73, the second ventilation path 74, the first blower 75, the second An air blower 77), a storage room (refrigeration room 2) including an outlet 80 for blowing out the cool air generated by the cooling part, a case part 11 that is movable in the front-rear direction and accommodates stored goods, and above the case part 11 And a cover portion 12 that covers the case portion 11 when the case portion 11 is in the retracted state. The indirect cooling is provided in the storage chamber and is indirectly cooled by the cool air around the case portion 11 and the cover portion 12. A chamber (chilled chamber 1) and a holding portion 9 that holds the case portion 11 pushed in and stored.

  Thereby, since the case part 11 can be hold | maintained with the holding | maintenance part 9, the case part 11 in a stored state can move, and it can prevent the clearance gap between the case part 11 and the cover part 12 becoming large. Therefore, the indirect cooling chamber (chilled chamber 1) can be kept in a highly airtight state, and the food can be prevented from drying. Moreover, the indirect cooling chamber which has high airtightness and hardly causes drying of food can be provided only by placing the case portion 11 in the retracted state and covering the case portion 11 with the cover portion 12. And compared with the case where decompression is accompanied like a low-pressure chamber, without using a strong member and a reinforcement member, the sealing property of an indirect cooling chamber can be improved easily and entry of cold air can be reduced.

  Further, in the refrigerator 1 according to the embodiment, the protruding portion 110 is provided on the lower surface of the case portion 11, and the holding portion 9 is pushed and deformed by the protruding portion 110 when the case portion 11 is in the retracted state. The spring part 90 which presses down is included. Thereby, the case part 11 made into the storage state by simple structure can be hold | maintained firmly. Further, since the holding is performed on the lower surface of the case portion 11 that is difficult for the user to visually recognize, it is also preferable from an aesthetic point of view.

  In addition, the spring portion 90 of the refrigerator 1 according to the embodiment has a first inclined portion 91 that contacts the protruding portion 110, and the first inclined portion 91 presses the protruding portion 110 as the case portion 11 is pushed. Inclined to weaken the force. Thereby, the force (force which guides case part 11 to the back side) to the direction which pushes case part 11 toward a stowed state can be generated. In other words, the spring part 90 can be given a force to move the case part 11 to the back side, which is the direction in which the spring part 90 is stabilized, so that the case part 11 in the retracted state can be firmly held. Thereby, the case part 11 can be kept in a stable state (stored state) so that no gap is generated between the case part 12 and the cover part 11.

  Moreover, the spring part 90 of the refrigerator 1 has the 2nd inclination part 92 which contacts the projection part 110 first, when the case part 11 is pushed in. Thereby, even if it moves to the direction which retracts case part 11 vigorously, the force which the projection part 110 collides with the spring part 90 can be escaped by inclination. Therefore, the impact on the protrusion 110 and the spring part 90 can be reduced, and the damage of the protrusion 110 and the spring part 90 can be eliminated.

  The protrusion 110 is a central portion of the case portion 11 in the left-right direction, and is provided near the back surface of the case portion 11. The holding portion 9 corresponds to the position of the protrusion 110 when the case portion 11 is stored. The protrusion 110 may be provided at a position where the protrusion 110 is pressed. Thereby, since the protrusion part 110 and the holding | maintenance part 9 are provided in the center part in the left-right direction, the case part 11 can be hold | maintained appropriately in the position near the center of the case part 11. FIG. Moreover, since the protrusion part 110 and the holding | maintenance part 9 are provided in the position of the back side of the case part 11, it is hard to visually recognize for a user and it is preferable also aesthetically.

  The protrusion 110 is a central portion of the case portion 11 in the left-right direction, and is provided near the front of the case portion 11. The holding portion 9 corresponds to the position of the protrusion 110 when the case portion 11 is stored. Thus, the protrusion 110 may be provided at a position where the protrusion 110 is pressed. Thereby, since the protrusion part 110 and the holding | maintenance part 9 are provided in the center part in the left-right direction, the case part 11 can be hold | maintained appropriately in the position near the center of the case part 11. FIG. In addition, since the protrusion 110 and the holding part 9 are provided near the front of the case part 11, it is easy to grasp whether or not the user has held the protrusion, and there is a large gap between the case part 11 and the cover part 12. It is not maintained in a state where the case part 11 is not properly stored.

  In addition, a seal member for closing a gap between the case portion 11 and the cover portion 12 is provided on either the case portion 11 or the cover portion 12. Thereby, the sealing property (sealing property when the cover part 12 and the case part 11 are overlap | superposed) of an indirect cooling chamber (chilled chamber 1) can be improved. Accordingly, it is possible to make it difficult to dry the food.

  Next, another embodiment will be described. In the above embodiment, the chilled chamber 1 has been described as an example of the indirect cooling chamber. However, it is not limited to the chilled room 1, but a storage room (for example, a storage room of about several degrees below freezing) provided in another refrigerator 100 may be used as an indirect cooling room.

  In the above-described embodiment, the example in which the seal member (14R, 14L, 14F, 14B) is provided to fill the gap between the cover portion and the case portion has been described. However, when the case portion is in the retracted state (when the cover portion and the case portion are overlapped), the cover portion and the case portion are formed so that the lower end edge portion of the cover portion and the upper end edge portion of the case portion are in contact with each other. The hermeticity may be improved. In other words, the cover portion and the case portion may be formed such that when they are overlapped, there is no gap between the cover portion and the case portion, or even if a gap is generated, the gap is within a predetermined allowable range.

  The embodiment of the present invention has been described above, but the scope of the present invention is not limited to this, and various modifications can be made without departing from the spirit of the invention.

  The present invention can be used for a refrigerator provided with an indirect cooling chamber.
