Description

  The present invention relates to a refrigerator-freezer provided with a freezer compartment.

  In recent years, under the influence of an increase in the number of dual-income households and the development of frozen foods, there are many opportunities for freezing and storing foods at home. For this reason, home refrigerator-freezers are mainly in the form of emphasizing freezer capacity and usability. In addition to increasing the capacity of the freezer compartment, the need for reducing the installation space of the refrigerator and the energy saving in the cooling operation has become important needs of society.

  As a refrigerator-freezer that places importance on the usability of a freezer compartment, for example, there is a refrigerator-freezer in which a plurality of containers having different heights are stacked in the freezer compartment (see, for example, Patent Documents 1 and 2). In patent documents 1, 2, it is comprised so that a container may also be pulled out with drawer | drawing-out of a freezer compartment door. And in patent document 2, the upper container is provided with a lid.

JP 2005-83681 A (summary, FIG. 2) JP 2007-271243 A (page 4, FIG. 3)

  In general, since there is a large temperature difference between the ambient temperature of the refrigerator-freezer and the temperature inside the refrigerator-freezer, condensation may occur on the surface of the refrigerator-freezer body. In order to prevent this dew condensation, a pipe heater is circulated in the main body of the refrigerator-freezer in the refrigerator-freezer for home use. The temperature of the pipe heater is about 30 ° C. to 40 ° C., and the pipe heater is usually installed close to the outer box sheet metal of the ceiling, back surface, side surface, and front flange of the refrigerator-freezer.

  With regard to the ceiling, back and side of the refrigerator, urethane foam insulation and vacuum insulation can be installed between the pipe heater and the inner plate of the refrigerator. be able to. However, a heat insulating material cannot be put into the front flange, and structurally, heat from the pipe heater is transferred to the sheet metal constituting the front flange and easily enters the interior. In particular, since the freezer compartment has a low temperature in the cabinet, there is more heat intrusion from the pipe heater than in other rooms, and there is a concern about the adverse effect on food storage quality and energy saving.

  In Patent Documents 1 and 2, although the improvement of usability of the freezer and the effect of suppressing the cold air leakage when the freezer door is closed, the heat intrusion from the pipe heater is not studied at all. There is a need for technology that suppresses heat intrusion.

  Further, in Patent Document 2, by covering the upper opening of the upper container, leakage of cold air when the door is opened is prevented, the temperature of the freezer room is hardly increased, and energy saving is realized. However, since the lid always comes out together with the upper container, the user has to open the lid each time, and there is a problem that usability deteriorates.

  This invention is made | formed in view of such a point, and it aims at providing the freezer refrigerator which can suppress the heat | fever penetration | invasion from a pipe heater to a freezer compartment. It is another object of the present invention to provide an easy-to-use refrigerator-freezer that does not require the lid of the upper container to be opened each time in a freezer compartment in which a plurality of containers are stacked.

The refrigerator-freezer according to the present invention, when a refrigerator-freezer body provided with a freezer compartment and a drawer-type door provided on the front surface of the freezer compartment are pulled out, is pulled out from the freezer compartment together with the drawer-type door, and is arranged vertically. A plurality of containers and a lid that covers the upper opening of the upper container of the plurality of containers, is movable in the front-rear direction with respect to the upper container, and is pulled out together with the drawer of the drawer-type door. The ceiling part of the freezer compartment has a pipe heater in the front, the ceiling part has a convex part on the freezer compartment side projecting toward the lid side and extending in the width direction behind the pipe heater, and the lid protrudes toward the ceiling side, and a lid side projecting portion extending in the width direction, the cover-side protrusion in a state where the pull-out type door closed is in contact with the front-rear direction to the freezing chamber side protrusion, The space between the lid and the ceiling of the freezer compartment is empty in front of the pipe heater. And is cut off in the rear space, the freezing chamber side protrusion to restrict the movement of the further forward of the lid where the drawer-type door is pulled out lid to a position visible presence of the lid is pulled out It also functions as a stopper .

FIG. 7 is an enlarged perspective view of the lid 8 of FIG. FIG. 8 is a cross-sectional view of the freezer when the drawer-type door 4a of the freezer compartment 4 in the refrigerator-freezer according to Embodiment 1 of the present invention is opened. FIG. 9 is an enlarged end view of a portion surrounded by a dotted line in FIG.

  In the freezer compartment 4, an upper container 6 and a lower container 7 are stored in the vertical direction between the freezer ceiling 12 and the freezer floor 16. The lower container 7 is configured to be pulled out in conjunction with the pull-out of the pull-out door 4a. The upper container 6 is arranged on the upper part of the lower container 7 so as to be movable in the front-rear direction with respect to the lower container 7, and is pulled out together with the lower container 7 in conjunction with the pull-out of the pull-out door 4a.

  When the drawer-type door 4a is closed, the lower container 7 is covered with the upper container 6 when the door is closed, and the rear container 7 has a cold air outlet through which cool air from a cooler (not shown) is blown out. 7a is opened. Further, the lower container 7 has a hole 8b (not shown) on its side surface, and an air passage through which the cold air blown into the lower container 7 from the rear cold air outlet 7a flows out of the lower container 7 from the side hole 8b. (FIG. 2).

  The upper container 6 has an upper opening covered with a lid 8 when the door is closed, and is opened as a cold air outlet 11 only at the rear. The lid 8 is configured to slide and move on flanges (not shown) provided on the left and right side walls of the upper container 6, and the front edge of the lid 8 increases the degree of adhesion with the front edge of the upper container 6. Therefore, a gasket 15 is provided. The lid 8 is made of a transparent material so as not to disturb the food take-out and storage properties.

  By sealing the upper container 6 with the lid 8, the degree of sealing is increased and it is possible to prevent cold air leakage. On the other hand, when cold air is blown into the upper container 6 from the rear cold air outlet 11, the upper container 6 The internal pressure increases, and it becomes difficult for cold air to enter the upper container 6. Then, there is a possibility that cold air that has become unable to enter the upper container 6 may cause a cooling failure due to entering the return air passage 40 without cooling the inside of the freezer compartment 4. Therefore, in the first embodiment, the lid 8 is provided with a plurality of holes 8b for allowing cold air to pass therethrough in the left-right direction in front of one half of the depth dimension of the freezer compartment 4. Thus, a flow path is formed in which the cool air blown into the upper container 6 from the rear cold air outlet 7a and cooled in the upper container 6 flows into the return air path 40 through the plurality of front holes 8b. Therefore, an increase in the internal pressure in the upper container 6 is suppressed, and the inside of the upper container 6 can be sufficiently cooled.

  The freezer compartment 4 includes a stopper 14 for restricting the forward movement position of the lid 8 on the freezer compartment ceiling 12. Further, the lid 8 is provided with a protrusion 8c that comes into contact with the stopper 14, and as shown in FIG. 8, when the drawer type door 4a is pulled forward by the user, the lid 8 is also moved forward together with the upper container 6. It moves so that it stops when the projection 8c comes into contact with the stopper 14 and does not protrude further. Specifically, the lid 8 is positioned forward to a position where the user can visually recognize the presence of the lid 8, for example, a position where the user can visually recognize the distal end portion (the handle portion 8a) of the lid 8 from above. The positional relationship between the protrusion 8c and the stopper 14 is set so that further forward movement from the position is restricted.

  Moreover, in this Embodiment 1, the structure which suppresses the heat penetration | invasion into the freezer compartment 4 from the pipe heater 9 is employ | adopted. Specifically, as shown in FIG. 3, a lid-side convex portion 8d that protrudes toward the freezer compartment ceiling 12 side and extends in the full width direction is provided on the front side of the lid 8, and the drawer-type door 4a is closed. In the state, the stopper 14 projecting downward from the freezer compartment ceiling 12 is in contact with the front-rear direction (the depth direction of the refrigerator-freezer), and the space before and after the lid-side convex portion 8d is physically cut off (FIGS. 2 and 3). . As a result, even if the heat generated by the pipe heater 9 travels through the front flange 10 and enters the cabinet, the air in the space 13 on the front side of the lid-side convex portion 8d is only warmed to the rear of the lid-side convex portion 8d. Some air, that is, air in the return air passage 40 is not warmed. In the first embodiment, the stopper 14 functions as a freezer compartment convex portion that blocks the space 13 from the return air passage 40 together with the lid convex portion 8d. In the first embodiment, the lid-side convex portion 8 d also functions as the handle portion 8 a of the lid 8.

  With the configuration as described above, the upper container 6 is pulled out together with the lower container 7 by pulling the pull-out door 4a forward. The lid 8 is also drawn forward together with the upper container 6, but when the lid 8 moves to a place where the user can visually recognize the lid 8, the protrusion 8c of the lid 8 abuts against the stopper 14, and the lid 8 Do not go forward. Therefore, the lid 8 is in a position where it cannot be visually recognized except the handle portion 8a from the user's field of view. Therefore, the user's view is not obstructed by the lid 8, and the visibility of the food is not hindered. Moreover, it is not necessary to open the lid 8 when food in the upper container 6 is stored or taken out, and stress is not given to the user in the opening / closing operation of the lid 8.

  When the user puts the lid 8 on the upper container 6, the upper container 6 can be sealed by pulling the lid 8, and cold air leakage can be prevented. Moreover, what is necessary is just to slide the upper stage container 6 back, when taking out a foodstuff from the lower stage container 7. FIG. When the drawer-type door 4a is closed, the lower container 7 moves rearward toward a predetermined storage position in the freezer compartment 4, and the lower container 7 is in the state where the lower container 7 is positioned at the storage position (FIG. 2). 7 is covered with the upper container 6, and the upper opening of the upper container 6 is covered with the lid 8.

  As described above, according to the first embodiment, the space between the lid 8 and the freezer ceiling 12 is formed by the lid-side convex portion 8d provided on the lid 8 and the stopper 14 provided on the freezer compartment 4. When the door is closed, the air warmed by heat transfer from the pipe heater 9 can be retained in the space 13 in front of the lid-side convex portion 8d. Therefore, the air in the return air passage 40 is not warmed, and the load increase of the cooler (not shown) can be suppressed, leading to energy saving.

  The space 13 functions as a heat insulating layer of air and has an effect of preventing heat from the pipe heater 9 and the outside air from entering the inside of the cabinet. Therefore, it can be expected that the amount of heat entering the pipe heater 9 and the heat from the outside air into the warehouse is reduced. As a result, it is possible to avoid an increase in the temperature in the cabinet and reduce the amount of power consumption.

  Further, since the lid 8 covering the upper container 6 has a structure in which the lid 8 does not come out further when the lid 8 is pulled out until the user can visually recognize when the door is opened. The stress required to open and close the lid 8 each time it is opened can be eliminated. Moreover, since the lid | cover 8 exists in the position which cannot be visually recognized except the handle part 8a, since it does not block a user's visual field, the visibility of a foodstuff is not inhibited.

  Further, since the lid 8 has a plurality of holes 8b in front of half of the depth of the upper container 6, the cold air blown into the upper container 6 from the rear of the upper container 6 in the freezer compartment 4 is in the upper container 6. It has a structure that passes through the inside and comes out of the upper container 6 from a plurality of holes 8b provided forward. Therefore, the cooling failure of the upper container 6 due to the increase in the internal pressure of the upper container 6 can be prevented, and efficient cooling can be performed. Moreover, since the hole 8b is located behind the lid-side convex portion 8d, the warmed air in the space 13 and the cool air in the upper container 6 do not mix, so the temperature in the upper container 6 The rise can be suppressed, leading to energy saving.

  In the first embodiment, the example in which the two containers of the upper container 6 and the lower container 7 are stacked and stored in the freezer compartment 4 is shown, but a configuration in which three or more containers are stacked and stored may be used. Of the plurality of containers drawn out together with the drawer-type door, the upper opening of the uppermost container may be provided with a lid for performing the above-described operation.
