Summary of the Invention

Problems to be Solved by the Invention

[0004] However, simply providing minute ribs has little effect of preventing the blockage of the suction port, and it is difficult to avoid blockage when a food packaging material or the like is attracted to the suction port. In particular, when the suction port is provided deep inside the inner wall on the bottom surface side of a storage compartment such as a vegetable compartment, a bag or the like that has fallen behind a vegetable case covers the suction port for return cold air, blocking the suction port and preventing cold air circulation, which may cause poor cooling of the refrigerator compartment.

[0005] An object of the present disclosure is to provide a refrigerator capable of preventing blockage of the suction port for cold air in a storage compartment.

Mode for Carrying Out the Invention

[0009] Hereinafter, each embodiment of the present disclosure will be described while referring to the drawings. In the following description, the same parts are denoted by the same reference numerals. Their names and functions are basically the same.

[0010] <Overall Configuration of Refrigerator> First, referring to FIGS. 1 to 4, the overall configuration of the refrigerator 1 according to the embodiment will be described.

[0011] The outer shape of the refrigerator 1 is mainly composed of a heat-insulating box body 10. A storage space of the refrigerator 1 is formed by this heat-insulating box body 10. The storage space formed by the heat-insulating box body 10 may be divided into a plurality of storage chambers by partition walls. For example, it is divided into a refrigerating chamber 11, a first freezing chamber 12, a vegetable chamber 13, an ice-making chamber 14, and a second freezing chamber 15. The refrigerating chamber 11 is arranged at the uppermost stage. The first freezing chamber 12 is arranged at the lowermost stage. The vegetable chamber 13, the ice-making chamber 14, and the second freezing chamber 15 are arranged between the refrigerating chamber 11 and the first freezing chamber 12. The vegetable chamber 13 is arranged above the ice-making chamber 14 and the second freezing chamber 15. The ice-making chamber 14 and the second freezing chamber 15 are arranged side by side. Although not shown, each storage chamber is provided with a door respectively. However, the arrangement of each storage chamber is not limited to this.

[0012] In this embodiment, the surface where the door is provided is referred to as the "front" or "front face" of the refrigerator 1, and the surface on the opposite side of the front is referred to as the "back". Also, in the normal arrangement of the refrigerator 1 installed on the installation surface, the upper side is referred to as the "upper side" of the refrigerator 1, and the lower side is referred to as the "lower side" of the refrigerator 1. The upper surface of the refrigerator 1 is referred to as the "upper surface", and the lower surface is referred to as the "bottom surface". The two surfaces other than the front, back, upper surface, and bottom surface are referred to as "side surfaces". In the normal arrangement, the left side as viewed from the front side of the refrigerator 1 is referred to as the "left side" of the refrigerator 1, and the right side is referred to as the "right side" of the refrigerator 1. The side surface located on the left side is referred to as the "left side surface", and the side surface located on the right side is referred to as the "right side surface". The direction of the front of the refrigerator 1 is the "front direction", the direction of the back is the "back direction", the direction of the upper surface is the "upward direction", the direction of the bottom surface is the "downward direction", the direction of the left side surface is the "left direction", the direction of the right side surface is the "right direction", the directions of the front and back are the "front-back direction", the directions of the upper surface and the lower surface are the "up-down direction" (H), and the directions of the two side surfaces are the "left-right direction" (W). In addition, not only for the refrigerator 1 but also in the description of each storage space and each member constituting the refrigerator 1, these expressions regarding directions may be used.

[0013] Among the above storage rooms, the refrigerating chamber 11 and the vegetable chamber 13 are classified as refrigerated storage rooms, and the first freezing chamber 12, the ice making chamber 14, and the second freezing chamber 15 are classified as frozen storage rooms. In the refrigerator 1 according to this embodiment, the refrigerated storage rooms are arranged on the upper stage side, and the frozen storage rooms are arranged on the lower stage side. However, in another embodiment, the frozen storage rooms may be arranged on the upper stage side and the refrigerated storage rooms may be arranged on the lower stage side.

[0014] The partition wall 59b that partitions between the refrigerated storage rooms on the upper stage side and the frozen storage rooms on the lower stage side is formed of a highly heat-insulating wall having a heat insulating material inside. Specifically, the refrigerated storage rooms on the upper stage side are the refrigerating chamber 11 and the vegetable chamber 13. Specifically, the frozen storage rooms on the lower stage side are the first freezing chamber 12, the ice making chamber 14, and the second freezing chamber 15. Furthermore, the partition wall 59a between the refrigerator compartment 11 and the vegetable compartment 13 is made of a heat-insulating resin material. In addition, the partition wall 59c separating the first freezer compartment 12, the ice-making compartment 14, and the second freezer compartment 15 is provided only at the opening (see Figure 4). In other words, inside the insulated box body 10, the freezer storage compartment is formed as a single space. This freezer storage compartment can also be collectively called the freezer compartment.

[0015] A chilled compartment 16 is provided within the refrigerator compartment 11. The chilled compartment 16 is located on the lower partition wall 59a within the refrigerator compartment 11. Next to the chilled compartment 16, a tank 18 is provided for supplying water to the ice-making compartment 14. The water in the tank 18 is supplied to the ice-making compartment 14 through a water supply pipe 19 located within the vegetable compartment 13. A vegetable case 17 is provided within the vegetable compartment 13 (see Figure 2).

[0016] Refrigerator 1 is equipped with a cooling device 32 that generates cold air. The cooling device 32 includes a refrigeration cycle, a control unit, etc. The refrigeration cycle consists of a compressor, condenser, expander, evaporator, etc., connected via refrigerant pipes through which the refrigerant flows. The cooling device 32 is located, for example, in a machine room 31 provided on the rear side of the refrigerator 1. Since the temperature inside the machine room 31 rises when the cooling device 32 is operating, the machine room 31 is located outside the insulated box 10. In addition to the cooling device 32, the machine room 31 is also equipped with a fan 33, etc. The fan 33 is used to circulate air between the machine room 31 and the storage space.

[0017] (Cold air path) Next, we will explain the cold air path in refrigerator 1. The cold air path is a path through which cold air supplied to at least one storage compartment circulates. This section describes the circulation path of the cold air generated in the machine room 31, which is supplied to the refrigerator compartment 11 and the vegetable compartment 13, and then returned to the machine room 31 after passing through each compartment.

[0018] Figure 2 shows the cold air path within the refrigerator compartment with arrows. Figure 3 also shows the cold air path within the refrigerator compartment when viewed from the front of refrigerator 1 with arrows.

[0019] Cold air is generated in the machine room 31 by the cooling device 32. In this embodiment, the machine room 31 is located behind the freezer compartments, such as the first freezer compartment 12, and the vegetable compartment 13 (see Figure 2). The cold air cooled by the cooling device 32 in the machine room 31 is sent to each storage compartment of the storage space by the fan 33.

[0020] The cold air supplied to the refrigerated storage compartments, such as the refrigerator compartment 11 and the vegetable compartment 13, is first sent to the refrigerator compartment 11 through the cold air duct 41. The cold air duct 41 is located at the rear of the refrigerator compartment 11 (see Figure 2, etc.). In this embodiment, the lower portion of the cold air duct 41 is located at the rear of the vegetable compartment 13. The cold air duct 41 is located above the machine room 31 and is in communication with the machine room 31.

[0021] In addition, the refrigerator 1 may have its machine compartment 31 located lower down. In this configuration, the cold air duct 41 is also provided behind the vegetable compartment 13.

[0022] A damper 34 is provided between the machine room 31 and the cold air duct 41. By opening and closing the damper 34, the flow of cold air supplied to the refrigerator compartment 11 can be turned ON / OFF.

[0023] As shown in Figure 1 and other figures, the cold air duct 41 is located approximately in the center of the insulated box 10 in the left-right direction and extends in the vertical direction. A cold air outlet 42 is provided at the boundary between the cold air duct 41 and the refrigerator compartment 11 (see Figure 1). In the example shown in Figure 1, the outlet 42 is positioned to extend vertically from the front of the cold air duct 41. Cold air that has passed from the machine room 31 through the cold air duct 41 is supplied into the refrigerated room 11 from the outlet 42. An outlet is also provided in the chilled compartment 16, and cold air from the cold air duct 41 is supplied to the chilled compartment 16 as well.

[0024] The cold air that has passed through the refrigerator compartment 11 and the chilled compartment 16 is sent to the vegetable compartment 13 through an inlet 43 located between the refrigerator compartment 11 and the vegetable compartment 13. The inlet 43 is realized by an opening 43a formed in the partition wall 59a that separates the refrigerator compartment 11 and the vegetable compartment 13 (see Figure 4). The opening 43a is located at the rear corner of the left end of either the refrigerator compartment 11 or the vegetable compartment 13 when viewed from the front.

[0025] The cold air 4(4b) that flows into the vegetable compartment 13 from the inlet 43 passes along the back side of the vegetable case 17 inside the vegetable compartment 13 and flows into the cold air return duct 45 from the intake port 44 located at the bottom of the vegetable compartment 13. In this embodiment, the intake port 44 is provided on the inner wall 13a on the bottom side of the vegetable compartment 13. The intake port 44 is located at the rear corner of the rightmost part of the vegetable compartment 13 when viewed from the front (see Figure 3). The cold air return duct 45 is located at the rear of the insulated box 10 and leads to the machine room 31. As a result, the cold air that flows from the intake port 44 into the cold air return duct 45 is returned to the machine room 31.

[0026] As described above, the cold air supplied from the cold air duct 41 to the refrigerator compartment 11 flows into the vegetable compartment 13 from the inlet 43, passes through the vegetable compartment 13, and is returned to the machine room 31 through the suction port 44 provided on the inner wall 13a on the bottom side of the vegetable compartment 13 and the cold air return duct 45. In short, the cold air that flows into the vegetable compartment 13 from the inlet 43 passes through the vegetable compartment 13 and is returned to the machine room 31 through the suction port 44 provided in the vegetable compartment 13.

[0027] Thus, the refrigerator 1 includes a plurality of storage compartments, including a vegetable compartment 13, and a cold air path through which cold air supplied to at least one of the plurality of storage compartments other than the storage compartments circulates. The following explanation will primarily focus on the case where the storage compartment is the vegetable compartment 13, but the storage compartment is not limited to this.

[0028] <Refrigerator Features> (Ventilated cover) Referring to Figures 5 to 11, the refrigerator 1 of this embodiment is, The vegetable compartment 13 is a storage room, The machine room 31 where the cooling device 32 is located, A cold air inlet 43 for supplying cold air to the storage room, A cold air intake 44 is provided in the storage compartment, It includes a ventilation cover 2 attached to the storage compartment side of the intake port 44.

[0029] The ventilation cover 2 is A connection opening 20 (see Figure 10(a)) that communicates with the suction port 44, A ventilation opening 21 is provided on a surface different from the opening surface of the connection opening 20 or the suction port 44, and communicates with the connection opening 20. The ventilation opening 21 has a spacer 22 that protrudes outward from the opening surface in a portion of the periphery of the ventilation opening 21. The spacer 22 is an example of a protruding portion. The spacer 22 protrudes outward from the opening surface of the ventilation opening 21X provided on the rear side.

[0030] The connection opening 20 is an opening provided on the lower surface of the ventilation cover 2, and is formed, for example, by an opening on the lower side of the internal space of the ventilation cover 2. When the ventilation cover 2 is attached to the intake port 44, it is preferable that the connection opening 20 has a size that includes the intake port 44 when viewed from above. The connection opening 20 communicates, for example, with a ventilation opening 21 provided on a surface other than the lower side of the ventilation cover, via the internal space of the ventilation cover 2.

[0031] According to this embodiment, even if food packaging material (bags) or the like falls to the rear of the vegetable case and is pushed to the back side and rests on the intake port 44 of the vegetable compartment 13, the ventilation cover 2, which has a ventilation opening 21 provided on a surface different from the opening surface of the intake port 44, ensures ventilation between the intake port 44 and the inside of the vegetable compartment 13, thereby preventing deterioration of cooling performance.

[0032] Although the ventilation opening 21 described above is located on a different surface from the opening surface of the connection opening 20, the ventilation cover 2 may further have an opening 25 located on the same surface as the opening surface of the connection opening 20. This reduces the ventilation resistance caused by the ventilation cover 2, especially in the normal case where the area around the ventilation cover 2 is not covered by anything in particular.

[0033] The total area of ​​the ventilation openings 21 is preferably equal to or greater than the opening area of ​​the connection opening 20, or equal to or greater than the opening area of ​​the suction port 44. The opening area of ​​the connection opening 20 is equal to or approximately the same as the opening area of ​​the suction port 44. This is to minimize pressure loss due to the ventilation cover 2. In particular, when a ventilation opening 21X is provided on the rear side, it is preferable that the opening area of ​​the ventilation opening 21X on the rear side alone is greater than or equal to the opening area of ​​the connection opening 20. This is to minimize pressure loss due to the ventilation cover 2. Furthermore, in order to minimize pressure loss due to the ventilation cover 2, it is preferable that the opening area of ​​the connection opening 20, which is the effective opening area communicating with the suction port 44, is as close as possible to the opening area of ​​the suction port 44.

[0034] In the ventilation cover 2, it is preferable that the ventilation opening 21X and the spacer 22 are provided at least on the rear side (see mainly Figure 9(b)). More specifically, the ventilation opening 21X and the protrusion 22 are provided on the rear side of the connection opening 20. In other words, the ventilation opening 21X and the protrusion 22 are provided on the rear side of the intake port 44.

[0035] The spacer 22 positions the ventilation opening 21(21X) of the ventilation cover 2 so that there is a gap between it and the rear inner wall 13b of the vegetable compartment 13. The rear side of the ventilation cover 2 is not in a direction where cold air is drawn in, and it is not easy for bags or the like to stick to it, so the spacer 22 creates a state in which cold air can enter the gap, but bags or the like cannot. As a result, even when the top, front, and side sides are blocked with bags or the like, cold air circulation can be maintained through the ventilation opening 21(21X) on the rear side of the ventilation cover 2.

[0036] In the ventilation opening 21X provided on the rear side, it is preferable that the spacer 22 is provided on the inside of the opening in the direction of the opening surface. It is preferable that multiple spacers 22 are provided at relatively narrow intervals. In this case, the spacer 22, which acts as a three-dimensional obstacle, is positioned in the center of the ventilation opening 21X where bags and the like are most likely to be sucked in, thereby making it easier to ensure ventilation in the ventilation opening 21X on the rear side. In the illustrated configuration, the spacer 22 is provided only near the top of the ventilation opening 21X on the rear side, but spacers may also be provided on the side. This can more reliably prevent bags or the like from reaching the ventilation opening 21X on the rear side. Furthermore, similar spacers 22 may be provided in the ventilation openings 21 and 25 located on at least one or the other side of both sides.

[0037] The ventilation cover 2 preferably has a plurality of ventilation openings 21. In this case, even if some of the ventilation openings 21 are covered with bags or the like, ventilation can still be ensured by the remaining ventilation openings 21 that are not covered by bags or the like.

[0038] If the ventilation cover 2 has a plurality of ventilation openings 21, it is preferable that the ventilation openings 21 are provided on multiple surfaces that are different from each other. More specifically, the ventilation openings 21 are provided on the back surface, as well as on at least one of the top surface, front surface, and side surface. Even if ventilation openings 21 on some sides are covered with a bag or the like, ventilation can still be ensured by ventilation openings 21 on other sides. For example, even if ventilation openings 21 on the top or front are covered with a bag or the like, ventilation can still be ensured by ventilation openings 21 on other sides.

[0039] The ventilation cover 2 preferably has a plurality of ventilation openings 21 provided at different positions in a direction perpendicular to the opening surface of the intake port 44. By providing multiple ventilation openings 21 in the vertical direction, even if some of the ventilation openings 21 are covered with a bag or the like, ventilation can be more easily ensured for the remaining ventilation openings 21 that are not covered by the bag or the like. For example, even if the ventilation openings 21 on the bottom side of the multiple ventilation openings 21 arranged in the vertical direction are covered with a bag or the like, ventilation can be more easily ensured for the remaining ventilation openings 21 on the top side. In this embodiment, the opening surface of the suction port 44 is substantially horizontal, but it may also be sloped. Furthermore, if the opening surface of the suction port 44 is horizontal, the multiple ventilation openings 21 are provided at heights different from the position of the opening surface of the suction port 44.

[0040] The ventilation cover 2 preferably has a plurality of ventilation openings 21 at different positions in a direction parallel to the opening surface of the intake port 44. By providing multiple ventilation openings 21 in the horizontal direction, even if some of the ventilation openings 21 are covered with a bag or the like, ventilation can be more easily ensured for the remaining ventilation openings 21 that are not covered by the bag or the like. For example, even if the ventilation openings 21 on the front side are covered with a bag or the like, ventilation can be more easily ensured for the remaining ventilation openings 21 on the back side.

[0041] In particular, it is preferable that multiple ventilation openings 21, whose opening surfaces are parallel to the sides or front, are provided within multiple parallel surfaces in a direction perpendicular to the opening surface. The direction perpendicular to the opening surface is, for example, the left-right direction or the front-back direction. By having the opening surfaces of the ventilation openings 21, to which bags or the like may stick, be on different layers, it is possible to avoid the simultaneous blocking of ventilation openings 21 facing the same direction, and even if some of the ventilation openings 21 are blocked, it becomes easier to ensure ventilation in the remaining ventilation openings 21.

[0042] Furthermore, it is preferable that multiple openings 25 whose opening surfaces are parallel to the opening surface of the suction port 44 are provided within multiple parallel, different planes in a direction perpendicular to the opening surface. The direction perpendicular to the opening surface is, for example, the up and down direction. By having the opening surfaces of the openings 25 to which bags or the like may stick are on different levels, it is possible to avoid the simultaneous blocking of openings 25 in the same direction, and even if some of the openings 25 are blocked, it becomes easier to ensure ventilation of the remaining openings 25.

[0043] The ventilation cover 2 may have ribs 23 that protrude outward from the opening surface of the ventilation opening 21. The ribs 23 are protrusions other than the spacers 22. That is, the ribs 23 are protrusions that protrude outward from the opening surfaces of the ventilation openings 21 on the side and front sides. The ventilation cover 2 may also have ribs 23a that protrude upward from the opening 25 on the top side. By providing protrusions such as ribs 23, 23a around the ventilation opening 21, it is possible to prevent the bag from sticking to the ventilation opening 21 even if it is attracted to it, thereby ensuring ventilation.

[0044] In the ventilation cover 2, the ventilation opening 21 may be formed by the outer opening of a cylindrical body 24 that protrudes to the outside of the ventilation cover 2. The cylindrical body 24 is a protrusion other than the spacer 22. That is, the cylindrical body 24 is a protrusion that protrudes outward from the opening surfaces of the ventilation openings 21 on the side and front sides, other than the ventilation opening 21X on the rear side. The ventilation cover 2 may also have a cylindrical body (not shown) that protrudes upward from the opening 25 on the top side. The cylindrical body 24 positions the opening surface of the ventilation opening 21 outward from the rest of the ventilation cover 2, and separates it three-dimensionally from other ventilation openings 21 or 25. This makes it easier to ensure ventilation even if other ventilation openings 21 or 25 are covered and blocked by a bag or the like. In particular, if the cylindrical body 24 is a cylindrical body whose axis is in a direction different from the direction perpendicular to the opening surface of the suction port 44, even if a bag or the like is attracted towards the suction port 44, the bag or the like will stick to the outer surface of the cylindrical body 24, and the ventilation opening 21, which is the outer opening of the cylindrical body 24, will not be easily covered by the bag or the like, thus ensuring ventilation through the ventilation opening 21.

[0045] (Matching part) In the illustrated configuration, the suction port 44 is slit-shaped (see Figure 8). The front guide portion 26 and side guide portion 27 of the ventilation cover 2 are inserted into the holes in this grid and fitted together, thereby fixing the ventilation cover 2 to the intake port 44.

[0046] By designing the shapes of the front guide portion 26 and the side guide portion 27 to fit only into predetermined positions in the holes of the grid, the ventilation cover can be easily positioned. In particular, if a ventilation opening 21X and a spacer 22 are provided on the rear side of the ventilation cover 2, the ventilation effect will not be achieved if the front and rear of the ventilation cover 2 are reversed. Therefore, it is preferable that the ventilation cover 2 is designed so that it cannot be reversed. As such a design, the distance L1 in the front-rear direction between the side guide portion 27 and the outer opening of the front cylindrical body 24 is made longer than the distance L2 in the front-rear direction between the side guide portion 27 and the outer opening of the front cylindrical body 24 (see Figure 10(b)). This prevents the side guide portion 27 from being inserted into the predetermined holes of the lattice of the intake port 44, as the cylindrical body 24 will interfere with the rear inner wall 13b of the vegetable compartment 13, even if the ventilation cover 2 is mistakenly installed in the reverse direction. Thus, it is preferable to provide a mechanism to ensure that the ventilation cover 2 is installed in the correct mounting direction and position. This ensures that the ventilation effect of this embodiment is more reliably achieved.

[0047] Furthermore, the side guide portion 27 is provided with claws 27a, and by simply inserting the side guide portion 27 so that the claws 27a catch in the holes of the grid of the intake port 44, the ventilation cover 2 can be prevented from coming off the intake port 44. In addition, the side guide portion 27 is flexible laterally, and the ventilation cover 2 can be easily removed by inserting a finger through the opening 25 and pressing the tip of the side guide portion 27 inward.
