In the case of cooling the freezing chamber 10, the cooler 21 is cooled by driving the compressor 29, and the cooler fan 22 is driven in a state where the freezing damper 27 is opened and the refrigerating damper 25 is closed. Accordingly, the air cooled by the cooler 21 is blown out from the air outlet 34 to the upper side of the containers 100, 101, 102 through the freezing-side flow path 26, and is supplied to the freezing chamber 10.
Part of the cool air blown out from the air outlet 34 toward the upper side of the containers 100, 101, 102 enters the containers 100, 101, 102 and contacts the stored articles, thereby directly cooling the stored articles. The remaining cool air flows forward of each container 100, 101, 102 and contacts the rear surface (storage room side) of the heat insulation door 110, flows downward in front of each container 100, 101, 102, and flows backward in the lower container 100. Thereafter, the air enters the return duct 19 from the suction port 19b provided on the rear surface of the freezing chamber 10, returns to the cooler chamber 23, exchanges heat with the cooler 21 again, and is cooled.
In the refrigerator 1, when the door 6a of the refrigerator compartment 6 is opened, the control board 70 supplies power of the driving power to the lighting device 80 to illuminate the inside of the refrigerator compartment 6.

An inclined surface 142 inclined so as to be lower toward the rear, in other words, the inclined surface 142 is inclined so that the tip of the protrusion 140 becomes thin is formed on the upper side of the protrusion 140.
(5) Lower container 100, middle container 101 and upper container 102
Next, a lower container 100, a middle container 101, and an upper container 102 provided in the freezing chamber 10 will be described.
The lower container 100 is: a container disposed at the lowest side of the 3 containers disposed in the freezing chamber 10. The lower container 100 is formed in a box shape with a bottom, which is surrounded by a front wall 100a, left and right side walls, and a rear wall and is opened upward. The lower container 100 is provided with: the storage depth is larger than the other containers 101 and 102 arranged in the freezing chamber 10, and is largest in the vertical direction.
The storage depth is: even when stored articles are stored in the container, the stored articles can be inserted into and removed from the freezing chamber 10 without coming into contact with other containers or members disposed in the freezing chamber 10. In the case of the present embodiment, as shown in fig. 4, the length H1 in the up-down direction from the inner bottom surface of the lower container 100 to the outer bottom surface of the middle container 101 is the length H2 in the up-down direction from the inner bottom surface of the middle container 101 to the outer bottom surface of the upper container 102 in the middle container 101, and the length H3 in the up-down direction from the inner bottom surface of the upper container 102 to the upper end of the front wall of the upper container 102 in the lower container 100. For example, the storage depth H1 of the lower container 100 may be 210 to 230mm, the storage depth H2 of the middle container 101 may be 60 to 80mm, and the storage depth H3 of the upper container 102 may be 105 to 125mm.
As described above, the lower container 100 is configured to: the pair of left and right container supports 120 held in fixed engagement on the freezing chamber 10 side of the heat-insulating door 110 can be pulled out of the refrigerator simultaneously with the opening operation of the heat-insulating door 110. The upper ends of the left and right side walls of the lower container 100 are formed: a sliding surface 100b that can be placed on a lower leg portion 101b provided in the middle container 101 and can slide in the front-rear direction is provided with a convex portion 100c protruding upward at the front of the sliding surface 100 b.
The middle container 101 provided above the lower container 100 is formed in a box shape with a bottom surrounded by a front wall 101a, right and left side walls, and a rear wall and opened upward, and is disposed below the bottom surface of the upper container 102 with a space therebetween. The middle container 101 is a container having a smaller storage depth than the other containers 100 and 102 disposed in the freezing chamber 10 and being the lowest in the vertical direction.
The middle layer container 101 is configured as: the amount of projection from the bottom surface to the upper end of the front wall 101a is smaller than the amount of projection from the bottom surface to the upper ends of the left and right side walls and the rear wall. The front ends of the left and right side walls are inclined so that the amount of projection from the bottom surface gradually decreases as the front direction moves. Accordingly, the gap between the middle container 101 and the upper container 102 is widened at the front end portion of the middle container 101.
A flange portion 101c that is inclined downward as going forward is provided at the upper end of the front wall 101a in a protruding manner. The flange 101c is provided at the front end portions of the left and right side walls so as to extend forward and parallel to the inclined portions.
Left and right side walls of the middle container 101 are provided with: lower leg 101b and upper leg 101d protruding outward in the width direction.
Lower leg portion 101b is located at the lower portions of the left and right side walls of middle container 101, and is provided at the front and rear portions of the left and right side walls, respectively. The lower leg 101b is placed on a sliding surface 100b, wherein the sliding surface 100b is provided at upper ends of left and right side walls of the lower container 100.
The upper leg 101d is provided at upper ends of left and right side walls of the middle tank 101 along the front-rear direction. The upper leg 101d is placed on a middle rail 127 (see fig. 5), wherein the middle rail 127 is provided on the left and right side walls of the inner box 4 that demarcates the freezing chamber 10 along the front-rear direction.
The middle container 101 is provided to the freezing chamber 10 in such a manner that: lower leg 101b and upper leg 101d slide along front-rear direction on sliding surface 100b of lower container 100 and intermediate guide 127, so that intermediate container 101 can be pulled out of the refrigerator independently of lower container 100.
In the closed state of the heat insulating door 110 shown in fig. 4, the lower leg 101b of the middle container 101 is supported on the sliding surface 100b so as to be positioned in front of the convex portion 100c of the lower container 100, and the upper leg 101d is supported on the middle guide rail 127.
When the heat insulating door 110 is opened from the closed state and the lower container 100 is pulled out of the refrigerator, the lower leg portion 101b is pressed forward by abutting against the front side of the convex portion 100c of the lower container 100, and the middle container 101 is pulled out of the refrigerator together with the lower container 100 (see fig. 5).
When the lower container 100 moves rearward along with the closing operation of the heat-insulating door 110, the front wall 100a of the lower container 100 is pressed rearward by abutting against the lower portion of the front wall 101a of the middle container 101, and the middle container 101 also moves rearward along with the lower container 100, and is stored in the refrigerator.
The upper container 102 is disposed above the middle container 101, is formed in a box shape with a bottom surrounded by a front wall 102a, right and left side walls, and a rear wall and opened upward, and is disposed at the uppermost layer among containers disposed in the freezing chamber 10.
Like the middle container 101, the upper container 102 is configured as: the amount of projection from the bottom surface to the upper end of the front wall 102a is smaller than the amount of projection from the bottom surface to the upper ends of the left and right side walls and the rear wall. The front ends of the left and right side walls are inclined so that the amount of projection from the bottom surface gradually decreases as the front direction moves. Accordingly, the distance between the upper container 102 and the heat-insulating partition wall 16 increases at the front end of the upper container 102.
A flange 102c that is inclined downward as going forward is provided at the upper end of the front wall 102 a. The flange 102c is provided at the front end portions of the left and right side walls so as to extend forward and parallel to the inclined portions.
The left and right side walls of the upper container 102 are provided with: the leg 102d protrudes outward in the width direction. The leg portions 102d are provided on the left and right side walls of the upper container 102 in the front-rear direction, and the leg portions 102d are placed on upper guide rails 128 (see fig. 5), wherein the upper guide rails 128 are provided on the left and right side walls of the inner box 4 that demarcates the freezing chamber 10 in the front-rear direction. That is, the upper container 102 is supported by the left and right side walls of the freezing chamber 10 via the upper guide 128.
The upper container 102 is provided to the freezing chamber 10 in such a manner that: the leg 102d slides along the upper rail 128 in the front-rear direction, so that the upper container 102 can be pulled out of the refrigerator independently of the lower container 100 and the middle container 101.
(6) Opening and closing operation of heat insulation door 110
Next, the opening and closing operation of the heat insulating door 110 will be described.
As shown in fig. 4, in a door-closed state in which the heat-insulating door 110 closes the front surface opening of the freezing chamber 10, the sealing member 117 is brought into close contact with the periphery of the opening of the refrigerator main body 2 by the magnetic force of the magnet disposed therein, thereby sealing (closing) the space between the heat-insulating door 110 and the front surface opening of the freezing chamber 10. At this time, a part of the weight of the stored articles stored in the lower container 100 and the middle container 101 acts on the heat insulation door 110 at a position where the container support 120 is fixed. That is, in the present embodiment, a part of the weight of the stored articles stored in the lower container 100 and the middle container 101 acts on the screw fixing portion 121a.
When the user pulls the grip portion 118 forward to open the heat-insulating door 110 in such a closed state, the weight of the stored articles stored in the lower container 100 and the middle container 101 is received at the position (screw fixing portion 121 a) where the heat-insulating door 110 fixes the container support 120, and the forward movement is restricted. Accordingly, when the grip portion 118 is pulled forward, a deformation force that moves the lower side rearward acts on the heat-insulating door 110, but the protrusion 140 provided on the door inner panel 112 of the heat-insulating door 110 abuts against the front wall 100a of the lower container 100, and the deformation movement of the heat-insulating door 110 is restricted.
In the present embodiment, since the gap 141 is provided between the protrusion 140 and the front wall 100a of the lower container 100, when the grip portion 118 is pulled forward, the door upper portion of the heat-insulating door 110 moves forward with respect to the center portion in the up-down direction. That is, the heat insulation door 110 can be rotated so that the upper side faces forward and the lower side faces backward with the position where the container support 120 is fixed as the center, and the gap 141 is eliminated.
Accordingly, the sealing member 117 provided in the heat-insulating door 110 is separated from the refrigerator main body 2 from the upper end of the heat-insulating door 110 downward. When the lower side of the heat-insulating door 110 moves rearward by a predetermined amount, the protrusion 140 provided on the door inner panel 112 of the heat-insulating door 110 abuts against the front wall 100a of the lower container 100.
(7) Effects of
According to the refrigerator 1 of the present embodiment, since the protrusion 140 protruding toward the front wall 100a of the lower container 100 is provided in the heat-insulating door 110, even if a deformation force that moves the lower side rearward acts on the heat-insulating door 110 when the user pulls the grip portion 118 forward, the protrusion 140 comes into contact with the front wall 100a of the lower container 100, and excessive deformation of the heat-insulating door 110 can be prevented.
In the present embodiment, when the grip portion 118 is pulled forward from the closed state of the heat-insulating door 110 with the gap 141 provided between the protrusion 140 and the front wall 100a of the lower container 100, the upper portion of the heat-insulating door 110 moves forward, and the lower portion of the heat-insulating door 110 moves rearward so as to eliminate the gap 141. Accordingly, the closing member 117 provided at the upper end of the heat-insulating door 110 is separated from the refrigerator main body 2, and even when the heat-insulating door 110 is large, the force (door opening force) required to open the heat-insulating door 110 can be greatly reduced. When the lower side of the heat-insulating door 110 moves rearward by a predetermined amount, the protrusion 140 provided on the door inner panel 112 of the heat-insulating door 110 abuts against the front wall 100a of the lower container 100, and thereby excessive rotation of the heat-insulating door 110 can be restricted, and deformation and breakage of the heat-insulating door 110 and the container support 120 can be prevented.
In the present embodiment, when the container support 120 is fixed to the heat-insulating door 110 at a position lower than the central portion of the heat-insulating door 110 in the vertical direction, the distance from the position where the container support 120 is fixed to the grip portion 118 can be increased, and the upper portion of the heat-insulating door 110 can be moved forward with a smaller force to open the door.
Further, when the container support 120 is fixed to the heat-insulating door 110 at a position lower than the central portion of the heat-insulating door 110 in the vertical direction, even if a large load acts on the heat-insulating door 110 at the position where the container support 120 is fixed, deformation such as occurrence of a gap between the lower end portion of the heat-insulating door 110 and the refrigerator main body 2 can be suppressed from occurring in the heat-insulating door 110 and the container support 120.
That is, when the weight of the stored articles stored in the lower container 100 and the middle container 101 is large and a large load acts on the position of the heat insulation door 110 where the container support 120 is fixed, if the position of the fixed container support 120 is located above the vertical central portion of the heat insulation door 110, the upper portion of the heat insulation door 110 is moved rearward and the lower portion of the heat insulation door 110 is moved forward, so that the heat insulation door 110 and the container support 120 are deformed. As a result, the sealing member 117 may be separated from the refrigerator main body 2 at the lower end of the heat insulating door 110, and the freezing chamber 10 may be opened. As in the present embodiment, if the container support 120 is fixed to the heat-insulating door 110 at a position lower than the central portion of the heat-insulating door 110 in the vertical direction, even if the weight of stored articles is large, it is difficult to move the lower portion of the heat-insulating door 110 forward, and the opening of the freezing chamber 10 can be suppressed at the lower end portion of the heat-insulating door 110.
In the present embodiment, when the inclined surface 142 inclined downward as going rearward is provided on the upper side of the protrusion 140 protruding from the freezing chamber 10 side of the heat-insulating door 110, the lower container 100 can be guided rearward by the inclined surface 142 and mounted at a predetermined position even if the bottom surface of the lower container 100 touches the upper side of the protrusion 140 when the lower container 100 is supported by the upper flange 122a of the container support 120.
In the present embodiment, the upper container 102, the middle container 101, and the lower container 100 are provided in the freezing chamber 10 so as to be vertically aligned, and the lower container 100 disposed at the lowermost side is largest in the vertical direction and is supported by the container support 120 fixed to the heat insulation door 110, and the upper container 102 is larger in the vertical direction than the middle container 101, and in the case of being supported by the inner wall of the freezing chamber 10, the upper container 102, the middle container 101, and the lower container 100 can vertically partition the inside of the freezing chamber 10, and therefore, the convenience in use is not impaired, and the volume of the freezing chamber 10 can be increased. The largest lower container 100 is constituted by: the amount of push and pull to be pulled forward is easily set to be large by being supported by the container support 120 fixed to the heat insulation door 110, and the load acting on the position of the heat insulation door 110 where the container support 120 is fixed can be reduced by supporting the 2 nd largest upper container 102 to the freezing chamber 10.
In the present embodiment, when the flange portions 102c, 101c inclined downward toward the front are provided at the upper ends of the front walls 102a, 101a of the upper-stage container 102, the middle-stage container 101, the distance between the upper-stage container 102 and the heat-insulating partition wall 16 and the distance between the middle-stage container 101 and the upper-stage container 102 are increased in the upper-stage container 102 and the front end portion of the middle-stage container 101. Accordingly, the cool air blown out from the air outlet 34 to the freezing chamber 10 flows from the rear to the front between the upper container 102 and the heat insulating partition wall 16, and between the middle container 101 and the upper container 102, and then is less likely to remain in the front end portions of the upper container 102 and the middle container 101, whereby the freezing chamber 10 can be cooled uniformly.
In this case, the cool air blown out from the air outlet 34 is likely to contact the heat insulating door 110 in front of the flange portions 101c and 102c, and dew condensation is generated on the outside (front side) of the refrigerator in this portion, but as in the present embodiment, when the thickness t1 of the heat insulating material 116 of the heat insulating door 110 in front of the flange portions 101c and 102c is larger than the thickness t0 of the heat insulating material 116 in front of the lower container 100, dew condensation can be prevented from being generated in the heat insulating door 110.
In the present embodiment, as shown in fig. 6, the case where the protrusions 140 are provided at both right and left end portions of the lower portion of the heat insulation door 110 has been described, but the present invention is not limited thereto. The protrusion 140 may be provided at an arbitrary position in the lateral direction of the heat insulating door 110, for example, 1 protrusion 140 may be provided at a central portion in the lateral direction of the heat insulating door 110, 1 protrusion 140 may be provided at each of both end portions and the central portion in the lateral direction, or a rib-shaped protrusion 140 may be provided extending from one end portion to the other end portion in the lateral direction. When the user pulls one end portion of the grip portion 118 in the left-right direction forward, a force that deforms the heat insulation door 110 so that the other end lower portion in the left-right direction moves rearward acts on the heat insulation door 110, but in the case where the protrusion 140 is provided at least the both end portions in the left-right direction of the heat insulation door 110, the protrusion 140 abuts against the front wall 100a of the lower container 100 at an early stage of deformation of the heat insulation door 110, and thus deformation of the heat insulation door 110 can be suppressed.
In the present embodiment, the case where the gap 141 is provided between the projection 140 and the front wall 100a of the lower container 100 has been described, but the projection 140 may be provided so as to abut against the front wall 100a of the lower container 100 without the user applying force to the heat insulation door 110, or a member having cushioning property may be provided in the gap 141. When the buffer member is provided in the gap 141, the door opening force required to open the heat insulation door 110 can be greatly reduced, and the impact when the projection 140 comes into contact with the front wall 100a of the lower container 100 can be alleviated.
