Description

refrigerator

The present invention relates to a refrigerator that suppresses a malfunction of a damper device that opens and closes an air passage that supplies air to a storage room.

In recent years, worktop refrigerators have become the mainstream in refrigerators having a plurality of storage rooms and a rated internal volume of 300 L or more. In a worktop refrigerator, a refrigerator compartment is arranged at the top, and other storage compartments are arranged below the refrigerator compartment. The opening on the front side of the refrigerator compartment is openable and closable, for example, with a double door. The other storage rooms are openable and closable with, for example, a drawer-type door. The other storage rooms are, for example, an ice making room, a small freezing room, a freezing room, and a vegetable room. In addition, there is a trend to increase the capacity of refrigerators so that all foods can be stored even in bulk purchases on weekends according to the lifestyle of the user.

In many refrigerators, the following configuration is adopted in order to keep each storage room of the refrigerator at a predetermined temperature. Specifically, the storage room is provided with a temperature sensor for detecting the temperature in the storage room. Further, a damper device that opens and closes the air passage is provided in an air passage that supplies cool air, which is air cooled by the cooler, to the storage room. This damper device has a part of an air passage for supplying cool air to the storage room. Further, the damper device includes a baffle that opens and closes the air path, and a drive unit that operates the baffle by a driving force of a motor. When the damper device closes the air passage that supplies cool air to the storage room, the baffle contacts the peripheral edge of the air passage in the damper device from above, and closes the air passage.

In the refrigerator, the inside of the housing is divided into a plurality of storage rooms by partitioning the inside of the housing composed of the inner box and the outer box with partitioning parts. Here, there has been proposed a conventional refrigerator in which a damper device is embedded in a partition part to increase the capacity of a storage room (for example, see Patent Document 1). More specifically, a recess for accommodating a lower portion of the damper device is formed in a partition part in which a part of the upper surface forms the lower surface of the storage room, behind a portion forming the lower surface of the storage room. In addition, the partition part having the concave portion is provided with a dam that projects upward in front of the concave portion in order to prevent moisture from entering the concave portion. The damper device is installed with at least a lower portion embedded in the recess. When the damper device is installed as described above, in a state where the baffle closes the air passage in the damper device, a contact portion between the baffle and the peripheral edge of the air passage in the damper device is disposed below the dam. It will be.

風 As described above, the air path for supplying cool air to the storage room is closed by the contact between the baffle and the peripheral edge of the air path in the damper device. That is, in a state in which the air path is closed, the surface of the baffle on the side in contact with the peripheral edge of the air path is in a state of being cooled by the cool air generated by the cooler. At this time, the temperature of the cool air generated by the cooler is as low as about −20 ° C. Therefore, if water adheres to the surface of the baffle on the side in contact with the periphery of the air path, the water freezes and the baffle and the periphery of the air path in the damper device are fixed, and the baffle may malfunction. May be. When the baffle malfunctions as described above, it becomes impossible to supply cool air to the storage room.

Further, as described above, when the damper device is embedded in the partition component and installed, in a state where the baffle closes the air passage in the damper device, a contact portion between the baffle and the peripheral edge of the air passage in the damper device is It will be located below the dam. That is, when the damper device is embedded and installed in the partition part, the condition is such that water easily adheres to the surface of the baffle on the side in contact with the peripheral edge of the air path. Further, when the damper device is embedded in a partition part constituting the lower surface of the storage room where the set temperature is in the refrigeration temperature zone, when water spills in the storage room, the water does not freeze in the storage room. It is easy to get over the dam. Therefore, when the damper device is embedded in the partition part constituting the lower surface of the storage room where the set temperature is in the refrigeration temperature zone, even when water passes over the dam, the side of the baffle that comes into contact with the peripheral edge of the air path. It is desirable to prevent water from adhering to the surface. The refrigerated temperature zone is a temperature zone higher than 0 ° C. That is, the storage room where the set temperature is in the refrigeration temperature zone is a storage room where the set temperature is higher than 0 ° C.

Here, as described above, the driving unit of the damper device operates the baffle by the driving force of the motor. Therefore, it is necessary to connect a lead wire to the drive unit of the damper device in order to supply power to the motor, transmit a control signal to the motor, and the like. The lead wire is routed while being housed in a groove formed in a heat insulating component around the damper device. At this time, conventionally, the way of leading the lead wire is determined after securing the cross-sectional area of the flow path of the air passage and determining the shape of the concave portion in which the damper device is embedded. For this reason, there is little design freedom in the arrangement of the grooves for accommodating the lead wires. Therefore, in the related art, the lead wire portion located in the concave portion in plan view may be routed to a position lower than the bank. For this reason, in a conventional refrigerator in which a damper device is embedded in a partition part constituting a lower surface of a storage room in which a set temperature is in a refrigeration temperature zone, in a conventional refrigerator, water passing over a dam flows along a groove for accommodating a lead wire and baffles. There is a possibility that the baffle adheres to the side of the air passage in contact with the peripheral edge of the air path, and the baffle adheres to the peripheral edge of the air path in the damper device, resulting in malfunction of the baffle. That is, in a conventional refrigerator in which a damper device is embedded in a partition part constituting a lower surface of a storage room in which a set temperature is a refrigeration temperature zone, it is still better to improve the operation of suppressing the malfunction of the baffle due to freezing. There was a problem that it was good.

The present invention has been made in order to solve the above-mentioned problem, and in a refrigerator in which a damper device is embedded in a partition part constituting a lower surface of a storage room where a set temperature is a refrigeration temperature zone, a baffle by freezing is provided. It is an object of the present invention to obtain a refrigerator that can suppress malfunctions more than before.

A refrigerator according to the present invention includes a storage room in which a set temperature is in a refrigeration temperature zone, a partition part in which a part of an upper surface forms a lower surface of the storage room, and a damper that opens and closes an air path for supplying air to the storage room. And a device, wherein the partitioning part is formed at the rear of a portion constituting the lower surface of the storage room, a recess is formed at the top thereof, and a lower portion of the damper device is accommodated therein, and a recess is formed in front of the recess. And a dam that protrudes upward. The damper device includes a baffle that forms a first air passage that is a part of an air passage that supplies air to the storage chamber, and that opens and closes the first air passage, and a motor. A driving unit for operating the baffle by the driving force of the motor, and a lead wire connected to the driving unit, wherein the baffle contacts the peripheral edge of the first air passage from above, The first air passage is closed. In a state in which the first air passage is closed, the contact portion between the baffle and the peripheral edge is disposed below the dam, and the lead wire is located in the recess in a plan view. The located portion is disposed above the bank.

In the refrigerator according to the present invention, a portion of the lead wire connected to the drive unit of the damper device, which is located in the recess for housing the lower portion of the damper device in plan view, is disposed above the dam. . For this reason, in the refrigerator according to the present invention, the water that has climbed over the weir adheres to the surface of the baffle on the side that comes into contact with the peripheral edge of the first air passage along the groove that houses the lead wire, as compared with the conventional case. Can be suppressed. Therefore, the refrigerator according to the present invention can suppress the malfunction of the baffle due to freezing as compared with the conventional case.

Embodiment.
Hereinafter, an example of a refrigerator according to the present invention will be described with reference to the drawings.

FIG. 1 is a front view of the refrigerator according to the embodiment of the present invention. FIG. 2 is a sectional view taken along line AA of FIG.
Refrigerator 100 includes a box-shaped housing 90 having an open front portion. The housing 90 includes an outer box 53 forming an outer peripheral surface of the housing 90 and an inner box 52 forming an inner peripheral surface of the housing 90. A heat insulating material 34 such as urethane foam is provided between the outer box 53 and the inner box 52. Note that a vacuum heat insulating material may be provided as the heat insulating material 34 between the outer box 53 and the inner box 52.

内部 The interior of the housing 90 is partitioned by partitioning components. Thereby, a plurality of storage rooms each having an opening at the front surface are formed in the housing 90. In the case of the present embodiment, the inside of the housing 90 is vertically partitioned by a partition component 35, a partition component 36, and a partition component 37. The partition 35 and the partition 36 are also horizontally separated by a partition (not shown). Thereby, the refrigerator 100 includes a refrigerator room 1, an ice making room 2, a small freezing room 3, a freezing room 4, and a vegetable room 5 as storage rooms.

Specifically, the refrigerator compartment 1 is arranged at the top of the storage compartment. That is, refrigerator 100 according to the present embodiment is a worktop refrigerator. The ice making room 2 and the small freezing room 3 are arranged below the refrigeration room 1. That is, a part of the upper surface of the partition part 35 constitutes the lower surface of the refrigerator compartment 1. Here, the refrigeration room 1 is a storage room in which the set temperature is in the refrigeration temperature zone. The refrigerated temperature zone is a temperature zone higher than 0 ° C. That is, the storage room where the set temperature is in the refrigeration temperature zone is a storage room where the set temperature is higher than 0 ° C. Therefore, the partition member 35 constitutes the lower surface of the storage room where the set temperature is in the refrigeration temperature zone by a part of the upper surface. Further, a part of the lower surface of the partition component 35 constitutes the upper surfaces of the ice making room 2 and the small freezing room 3. In addition, a part of the upper surface of the partition member 36 constitutes the lower surface of the ice making room 2 and the small freezing room 3. The freezing room 4 is arranged below the ice making room 2 and the small freezing room 3. That is, a part of the lower surface of the partition component 36 constitutes the upper surface of the freezer compartment 4. Further, a part of the upper surface of the partition member 37 constitutes the lower surface of the freezer compartment 4. The vegetable room 5 is arranged below the freezing room 4. That is, a part of the lower surface of the partition part 37 constitutes the upper surface of the vegetable compartment 5. Note that the refrigerator compartment 1, the ice making compartment 2, the small freezing compartment 3, the freezing compartment 4, and the vegetable compartment 5 are examples of a storage compartment of the refrigerator 100. The type and arrangement of the storage room provided in refrigerator 100 are not limited to the above-described configuration.

開口 Each opening formed in the front of these storage rooms is covered with a door so that it can be opened and closed. Specifically, a left door 6 and a right door 7 are provided in an opening on the front surface of the refrigerator compartment 1. The left end of the left door 6 is rotatably connected to the housing 90. The right end of the right door 7 is rotatably connected to the housing 90. That is, the opening on the front surface of the refrigerator compartment 1 is openably and closably covered by the double door. The opening at the front of the ice making chamber 2 is openably and closably covered by a drawer-type door 33. The opening on the front surface of the small freezing room 3 is openably and closably covered by a drawer type door 30. The opening at the front of the freezer compartment 4 is openably and closably covered by a drawer-type door 31. The opening at the front of the vegetable compartment 5 is openably and closably covered by a drawer-type door 32.

(4) In the refrigerator compartment 1, a plurality of pockets 20 for storing items are provided at different positions in the height direction. In the present embodiment, three pockets 20 are attached to at least one of the left door 6 and the right door 7. Further, the inside of the refrigerator compartment 1 is partitioned by three shelves 19. The lower part of the lowermost shelf 19 is a chilled room 17. The chilled room 17 is set to a temperature lower than the temperature of the refrigerator room 1. For example, when the temperature of the refrigerator compartment 1 is about 3 ° C., the temperature of the chilled compartment 17 is set to about 0 ° C., for example. The chilled chamber 17 is provided with a case 18 for storing stored items. Further, the small freezing room 3 is provided with a case 25 for storing stored items. Further, the freezer compartment 4 is provided with an upper case 26 and a lower case 27 for storing stored items. The vegetable room 5 is provided with an upper case 28 and a lower case 29 for storing the stored items.

(4) The refrigerator 100 includes a refrigerating cycle for cooling each storage room. This refrigeration cycle is a general one, and is configured by sequentially connecting a compressor 14, a condenser (not shown), a throttle mechanism such as a capillary (not shown), and a cooler 11 in sequence. That is, the refrigerant compressed to a high temperature and a high pressure by the compressor 14 is sent to the condenser, and radiates heat mainly outside the refrigerator 100 to be condensed. The condensed refrigerant is sent to the cooler 11 after being decompressed by the throttle mechanism. Then, the refrigerant sent to the cooler 11 cools the air around the cooler 11.

The cooler 11 is provided in a cooler room 91 formed behind the freezing room 4. The cooler room 91 is separated from the freezing room 4 by a fan grill 15. That is, the cooler 11 cools the air in the cooler chamber 91. Further, the cooler room 91 and each storage room communicate with each other through an air passage. In the cooler room 91, an in-compartment fan 10 is provided downstream of the cooler 11. That is, by driving the in-compartment fan 10, the air cooled by the cooler 11 circulates and cools each storage room.

For example, the air path component 21 is provided at the rear part of the housing 90. The air path component 21 forms the back surface of the refrigerator compartment 1. Note that, as described above, the chilled chamber 17 is also formed in the refrigerator compartment 1. The air path component 21 also forms the back surface of the chilled chamber 17. An air path 24 is formed in the air path component 21. Further, the air path component 21 is formed with, for example, a plurality of air outlets 22 that communicate the air path 24 with the refrigerator compartment 1. That is, the cool air supplied from the cooler room 91 to the air passage 24 is blown out from the outlet 22 into the refrigerator compartment 1. The air passage 24 communicates with the cooler room 91 via an air passage formed in the damper device 9 described later. That is, the air passage 24 and the air outlet 22 constitute an air passage for supplying air from the cooler room 91 to the refrigerator compartment 1 together with an air passage formed in the damper device 9 described later. The air path component 21 is also provided with an air path for supplying air from the cooler chamber 91 to the chilled chamber 17. In the present embodiment, the air path component 21 includes, as an air path that supplies air from the cooler chamber 91 to the chilled chamber 17, an air path 80 described later communicating with the cooler chamber 91, An air outlet 23 communicating with the chamber 17 is formed. That is, the cool air supplied from the cooler room 91 to the air passage 80 is blown out from the outlet 23 into the chilled room 17.

Here, the cool air generated by the cooler 11 is about −20 ° C., which is lower than the set temperature of the refrigerator compartment 1. For this reason, a damper device 9 is provided between the air passage 24 of the air passage component 21 and the cooler room 91. The amount of cold air supplied from the cooler room 91 to the refrigerator compartment 1 is adjusted by opening and closing the air passage for supplying air from the cooler room 91 to the refrigerator compartment 1 by the damper device 9. Is kept near the set temperature.

Specifically, the refrigerator 100 includes a temperature sensor 38 for detecting the temperature in the refrigerator compartment 1. The temperature sensor 38 is attached, for example, to the surface of the air path component 21. In addition, as long as the temperature in the refrigerator compartment 1 can be detected, the installation position of the temperature sensor 38 is arbitrary. Further, the damper device 9 includes a baffle 45 that opens and closes an air path formed in the damper device 9. Further, the refrigerator 100 includes a control board 16 that operates the baffle 45 based on the temperature detected by the temperature sensor 38. The control board 16 operates the baffle 45 so that the temperature detected by the temperature sensor 38 becomes the set temperature of the refrigerator compartment 1, and adjusts the amount of cool air supplied from the cooler compartment 91 to the refrigerator compartment 1. The cool air supplied to the refrigerator compartment 1 returns to the cooler room 91 through a return air passage (not shown), and is cooled again by the cooler 11.

In the present embodiment, the control board 16 controls other than the operation of the baffle 45. For example, in refrigerator 100 according to the present embodiment, at least a part of the storage rooms is provided with a heater for temperature compensation. Further, in refrigerator 100 according to the present embodiment, a dew-prevention heater is installed on partition plate 8 and the like arranged between left door 6 and right door 7. The control board 16 also controls energization of these heaters.

By the way, in the conventional refrigerator, there is a refrigerator separately provided with a cooler for cooling the air supplied to the freezer compartment and a cooler for cooling the air supplied to the refrigerator compartment. In this type of refrigerator, the air can be cooled to a temperature near the set temperature of the refrigerator by the cooler, and the air can be supplied to the refrigerator. For this reason, this type of refrigerator often does not require a damper device for adjusting the amount of cold air supplied to the refrigerator. However, this type of refrigerator needs to be provided with an internal fan for each cooler. Further, in this type of refrigerator, the temperature of the air supplied to the storage chamber is determined by the flow rate of the refrigerant flowing to each cooler, so that the control of the flow rate of the refrigerant flowing to each cooler becomes very complicated.

On the other hand, the refrigerator 100 according to the present embodiment supplies the air cooled by the same cooler 11 to both the refrigerator compartment 1 and the freezer compartment 4. For this reason, as described above, the refrigerator 100 according to the present embodiment needs to adjust the amount of cool air supplied to the refrigerator compartment 1 by the damper device 9. However, in the refrigerator 100 according to the present embodiment, it is possible to easily control the flow rate of the refrigerant flowing to the cooler 11, and to easily control the temperature in the refrigerator compartment 1.

(4) When the operation of the refrigerator 100 is continued, frost adheres to the cooler 11. For this reason, the refrigerator 100 is provided with a defrost heater 12 for melting frost attached to the cooler 11. The energization of the defrost heater 12 is controlled by the control board 16. Refrigerator 100 also includes a drain pan 13 that receives water generated by defrosting of cooler 11. The drain pan 13 is installed in a machine room 92 formed below the housing 90. The compressor 14 is also installed in the machine room 92. Therefore, the temperature inside the machine room 92 is relatively high. Therefore, the water discharged to the drain pan 13 evaporates.

Next, details of the damper device 9 will be described.

FIG. 3 is an exploded perspective view of the refrigerator damper device according to the embodiment of the present invention as viewed from the front left side. That is, FIG. 3 is an exploded perspective view of the damper device 9 viewed from the front left side of the refrigerator 100. FIG. 4 is a vertical sectional view of the refrigerator damper device according to the embodiment of the present invention as viewed from the right side. That is, in FIG. 4, the left side of the drawing is the front side of the refrigerator 100 and the front side of the damper device 9, and the right side of the drawing is the rear side of the refrigerator 100 and the rear side of the damper device 9. FIG. 4A shows a state of the damper device 9 in which the first air passage 47 is open. FIG. 4B shows a state of the damper device 9 in which the first air passage 47 is closed. FIG. 5 is a perspective view of the damper device of the refrigerator according to the embodiment of the present invention as viewed from the rear right side. That is, FIG. 5 is a perspective view of the damper device 9 viewed from the rear right side of the refrigerator 100. In the following, when the front-rear direction and the left-right direction of the configuration of the refrigerator 100 are described, the direction in which the configuration is installed in the refrigerator 100 is assumed.

The damper device 9 includes a driving unit 39, a frame unit 40, and a baffle 45. The housing of the drive section 39 and the frame section 40 are fastened with screws 41. The drive unit 39 includes a motor 42 that is, for example, a stepping motor, and a plurality of gears 43 that reduce the rotation of the motor 42. Further, the driving section 39 includes a driving pin 44 connected to one of the plurality of gears 43 and outputting the rotation of the motor 42 after deceleration by the plurality of gears 43. The driving pin 44 is connected to one of the lateral ends of the baffle 45. That is, the driving section 39 operates the baffle 45 by the driving force of the motor 42.

A first air passage 47 which is a through hole is formed in the frame portion 40. The first air path 47 is an air path that connects the cooler room 91 and the air path 24 of the air path component 21. That is, the first air passage 47 forms a part of an air passage that supplies air from the cooler room 91 to the refrigerator compartment 1. Further, the frame portion 40 includes a rib 48 protruding upward at a peripheral portion of the first air passage 47.

The baffle 45 opens and closes the first air passage 47, and is disposed above the first air passage 47 of the frame unit 40. One of the lateral ends of the baffle 45 is connected to the driving pin 44 of the drive unit 39 as described above. The other of the lateral ends of the baffle 45 is rotatably connected to the frame unit 40. The other rotation center of the lateral end of the baffle 45 is arranged coaxially with the center axis of the driving pin 44. For this reason, the baffle 45 can swing about the center axis of the driving pin 44 by the driving force of the motor 42 of the driving unit 39.

The baffle 45 has a seal member 46 on one surface. The sealing material 46 is, for example, a polyethylene sealing material that hardly contains water. As shown in FIG. 4B, when the baffle 45 rotates so as to approach the first air passage 47, the sealing material 46 comes into contact with the rib 48 around the first air passage 47 from above. As a result, the first air passage 47 is closed, and the air passage for supplying air from the cooler room 91 to the refrigeration room 1 is also closed. Further, as shown in FIG. 4A, when the baffle 45 rotates so as to separate from the first air passage 47, the seal member 46 separates from the rib 48 on the peripheral edge of the first air passage 47. Thereby, the first air passage 47 is opened, and the air passage for supplying air from the cooler room 91 to the refrigerator compartment 1 is also opened.

Here, as described above, the driving unit 39 of the damper device 9 operates the baffle 45 by the driving force of the motor 42. For this reason, it is necessary to connect a lead wire to the drive unit 39 of the damper device 9 in order to supply power to the motor 42, transmit a control signal to the motor 42, and the like. Therefore, the damper device 9 includes a lead wire 68 described later. As shown in FIG. 5, the drive section 39 includes a connection section 49 at an upper portion on the right rear side. A later-described lead wire 68 is connected to the connection portion 49 using, for example, a connector.

The damper device 9 according to the present embodiment is a damper device in which only the first air passage 47 communicating with the refrigerator compartment 1 is formed as an air passage communicating with the storage room. That is, the damper device 9 according to the present embodiment is a so-called single type damper device. However, in the conventional damper device, two air passages communicating with different storage rooms are formed, and there is also a damper device that opens and closes each air passage with two independently operating baffles. That is, a so-called twin type damper device also exists in the conventional damper device. The damper device 9 according to the present embodiment may be such a twin-type damper device. When the damper device 9 is a twin type, the damper device 9 can adjust the amount of cold air supplied to the storage room other than the refrigerator room 1 in addition to the amount of cold air supplied to the refrigerator room 1. Become.

Subsequently, an installation configuration of the damper device 9 will be described.
The front part of the upper surface of the partition component 35 constitutes the lower surface of the refrigerator compartment 1. The damper device 9 is installed so that the lower part of the damper device 9 is buried behind a portion constituting the lower surface of the refrigerator compartment 1 in the partition part 35. In the present embodiment, the damper device 9 and the heat insulating part 59 installed on the upper portion of the damper device 9 are assembled in advance as a damper device unit ASSY64. And this damper device part ASSY64 is attached to the partition component 35. Therefore, hereinafter, the damper device section ASSY64 will be described first. After that, a method of attaching the damper device assembly ASSY64 to the partition component 35 will be described.

FIG. 6 is an exploded perspective view of the damper device assembly ASSY of the refrigerator according to the embodiment of the present invention as viewed from the rear right side. FIG. 7 is a perspective view of the damper device assembly ASSY of the refrigerator according to the embodiment of the present invention as viewed from the front left side.
The heat insulating component 59 is a component formed of a heat insulating material such as expanded styrene. The heat insulating component 59 is combined with the damper device 9 so as to cover the damper device 9 from above. A second air passage 55a is formed in the heat insulating component 59. The second air path 55a is located above the first air path 47 of the damper device 9 and below the air path 24 of the air path component 21. The second air path 55 a communicates with the first air path 47 of the damper device 9 and the air path 24 of the air path component 21, and a part of the air path that supplies air from the cooler chamber 91 to the refrigerator compartment 1.
