Modes for Carrying Out the Invention

[0008] (Knowledge, etc. on which the present disclosure is based) When the inventors came up with the present disclosure, there was a refrigerator in which a thermopile for detecting the temperature of foodstuffs stored in an upper case was provided inside a duct cover of the refrigerator, the thermopile was housed with the periphery of the sensor covered with a heat insulating material between the front end of the duct cover and a ventilation fan so that the cold air did not touch it, and the wiring of the thermopile was connected to the wiring of a control board at a connector housing part. However, in the conventional technology, when attaching the duct cover, it is necessary to perform wiring connection of the thermopile, etc., and in order to suppress condensation, etc., it is necessary to form the duct cover into a complicated shape so that cold air does not enter the connector housing part. The inventors discovered such a problem and arrived at the constitution of the subject matter of the present disclosure in order to solve that problem. Therefore, the present disclosure provides a refrigerator that does not require complicated molding, can easily connect connectors, and can easily close a connector housing part.

[0009] Hereinafter, embodiments will be described in detail with reference to the drawings. However, there may be cases where a more detailed description than necessary is omitted. For example, there may be cases where a detailed description of already well-known matters or a redundant description of substantially the same constitution is omitted. Note that the attached drawings and the following description are provided for those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims thereby.

[0010] (Embodiment 1) Hereinafter, Embodiment 1 will be described using the drawings. [1-1. Configuration] [1-1-1. Overall Configuration of Refrigerator] FIG. 1 is a front view showing the internal structure of a refrigerator 1 according to Embodiment 1. In the figure, reference symbol X indicates the right side of the refrigerator 1, reference symbol Y indicates the front of the refrigerator 1, and reference symbol Z indicates the upper side. Note that the right side of the refrigerator 1 here is the right side for a person when the person views the refrigerator 1 from the front side.

[0011] The refrigerator 1 includes a box-shaped refrigerator body 2 that opens forward. The refrigerator body 2 is composed of a metal outer box 3, a rigid resin inner box 4, and a foamed heat insulating material 5 foamed and filled between the outer box 3 and the inner box 4. The inside of the refrigerator body 2 is partitioned into a plurality of compartments 11, 13, 15, 17, and 19 by respective heat insulating partition walls 6, 6A, 7, and 8.

[0012] At the uppermost part inside the refrigerator body 2, a refrigerating compartment 11 is formed. A plurality of shelf boards 12 are provided in the refrigerating compartment 11, and a partial compartment 11a is provided at the lower part. The refrigerating compartment 11 is a compartment for refrigerated storage and is set and cooled to a temperature low enough not to freeze, specifically, usually 1 to 5°C. The partial compartment 11a provided in the refrigerating compartment 11 is set and cooled to a temperature of about -3°C, which is lower than that of the refrigerating compartment 11.

[0013] Inside the refrigerator body 2, below the refrigerating compartment 11, an ice-making compartment 13 and a switching compartment 15 are formed side by side on the left and right. The ice-making compartment 13 located on the left side is a compartment for freezing water to generate ice and is set to a freezing temperature zone. The switching compartment 15 located on the right side of the ice-making compartment 13 can widely switch the cooling temperature from, for example, a freezing temperature zone set to -22 to -18°C and cooled to, for example, a refrigerating temperature zone set to 1 to 5°C and cooled. The ice-making compartment 13 and the switching compartment 15 constitute the second freezing compartment of the present disclosure.

[0014] Inside the refrigerator body 2, below the ice-making compartment 13 and the switching compartment 15, a vegetable compartment 17 is formed. The vegetable compartment 17 is a compartment set to a temperature equal to or slightly higher than that of the refrigerating compartment 11, specifically, 2 to 7°C and cooled. Since this vegetable compartment 17 becomes high humidity due to moisture emitted from stored foods such as vegetables, it may condense if it gets too cold locally. Therefore, by setting the temperature relatively high, the cooling capacity is reduced, and the occurrence of condensation due to local overcooling is suppressed.

[0015] Inside the refrigerator body 2, below the vegetable compartment 17, a freezer compartment 19 is formed. The freezer compartment 19 is a compartment set to the freezing temperature range. Specifically, it is usually set and cooled to -22 to -18°C. However, for improving the frozen storage state, it is set and cooled to a low temperature such as -30°C or -25°C.

[0016] Each of the compartments 11, 13, 15, 17, and 19 can be opened and closed by a rotary door or a drawer-type door 15a, 17a, 19a (see Fig. 2) that adopts the same heat insulation structure as the refrigerator body 2.

[0017] At approximately the center in the vertical direction inside the refrigerator body 2, a horizontal plate-shaped first heat insulation partition wall 6 is provided. The first heat insulation partition wall 6 vertically partitions the refrigerator compartment 11 from the ice-making compartment 13 and the switching compartment 15.

[0018] The switching compartment 15 and the ice-making compartment 13 are partitioned by a fourth heat insulation partition wall 6A extending downward from the first heat insulation partition wall 6. Further, the lower end of the fourth heat insulation partition wall 6A is connected to a horizontal plate-shaped second heat insulation partition wall 7. The second heat insulation partition wall 7 partitions the switching compartment 15 and the ice-making compartment 13 from the vegetable compartment 17.

[0019] Inside the refrigerator body 2, below the second heat insulation partition wall 7, a horizontal plate-shaped third heat insulation partition wall 8 is formed. The third heat insulation partition wall 8 partitions the vegetable compartment 17 from the freezer compartment 19.

[0020] Hereinafter, in the refrigerator 1, the space to be cooled that combines the refrigerator compartment 11, the ice-making compartment 13, the switching compartment 15, the vegetable compartment 17, and the freezer compartment 19 is referred to as the compartment to be cooled S.

[0021] Figure 2 is a cross-sectional view taken along the line II-II of Figure 1. As shown in Figure 2, a cooling chamber 20 is provided behind the vegetable chamber 17, that is, behind the cooled chamber S. The cooling chamber 20 is a space partitioned by a resin-made cooler cover 24. Inside the cooling chamber 20, a cooler 21 is arranged. The cooler 21 is a fin-tube type heat exchanger, which is a part of the refrigeration circuit provided in the refrigerator 1 and functions as an evaporator. Therefore, when the refrigeration circuit of the refrigerator 1 operates, the surrounding air is cooled.

[0022] In the cooling chamber 20, a cooling fan 23 is provided at a position above the cooler 21. The cooling fan 23 is arranged so as to be fitted into the opening 24a of the cooler cover 24. The opening 24a communicates the inside and outside of the cooling chamber 20 in the front-rear direction, and the cooling fan 23 blows the air inside the cooling chamber 20 forward through the opening 24a. Each chamber 11, 13, 15, 17, 19 of the refrigerator 1 is cooled by the air inside the cooling chamber 20 blown by the cooling fan 23.

[0023] Also, at the lower end of the cooling chamber 20, a tray-shaped water receiving tray 25 is provided. The water receiving tray 25 is located below the cooler 21 and receives the defrost water generated on the surface of the cooler 21 by the operation of the heater 27. The heater 27 is a heating device that defrosts the cooler 21 by operation. The heater 27 is arranged between the water receiving tray 25 and the cooler 21. In the present embodiment, the heater 27 is an electric glass heater.

[0024] Figure 3 is an explanatory diagram showing the configuration of the air passage in the refrigerator 1. As shown in FIG. 3, a refrigerator duct 31 is formed on the rear side of the refrigerator compartment 11. The refrigerator duct 31 communicates with the blowing side of the cooling fan 23 via a refrigerator compartment damper 31a that can be opened and closed. A refrigerator compartment air outlet 31b that opens toward the inside of the refrigerator compartment 11 is formed in the refrigerator duct 31. Therefore, the air blown out by the cooling fan 23 is blown out into the refrigerator compartment 11 via the refrigerator compartment damper 31a, the refrigerator duct 31, and the refrigerator compartment air outlet 31b. Further, an open refrigerator compartment return port 32a is formed in the refrigerator compartment 11. The refrigerator compartment return port 32a communicates with the cooling chamber 20 via a refrigerator compartment return air duct 32. Therefore, the air in the refrigerator compartment 11 returns to the cooling chamber 20 via the refrigerator compartment return port 32a and the refrigerator compartment return air duct 32. Further, the partial compartment 11a communicates with the blowing side of the cooling fan 23 via a possible partial compartment damper 31c.

[0025] An open ice-making compartment air outlet 33b is formed in the ice-making compartment 13. The ice-making compartment air outlet 33b serves as an entrance when the air blown out by the cooling fan 23 flows into the ice-making compartment 13. That is, the ice-making compartment air outlet 33b communicates with the blowing side of the cooling fan 23. Further, an open ice-making compartment return port 34a is formed in the ice-making compartment 13. The ice-making compartment return port 34a communicates with the cooling chamber 20 via an ice-making compartment return air duct 34. Therefore, the air blown out by the cooling fan 23 flows into the ice-making compartment 13 via the ice-making compartment air outlet 33b, and then returns to the cooling chamber 20 via the ice-making compartment return port 34a and the ice-making compartment return air duct 34.

[0026] As shown in FIG. 3, the switching chamber 15 communicates with the blowing side of the cooling fan 23 via a switching chamber damper 35a that can be opened and closed. The air blown out by the cooling fan 23 flows into the switching chamber 15 via the switching chamber damper 35a. Further, an open switching chamber return port 36a is formed in the switching chamber 15. The switching chamber return port 36a communicates with the cooling chamber 20 via a switching chamber return air duct 36. Therefore, the air blown out by the cooling fan 23 flows into the switching chamber 15 via the switching chamber damper 35a and the switching chamber air outlet 35b, and then returns to the cooling chamber 20 via the switching chamber return port 36a and the switching chamber return air duct 36.

[0027] In the vegetable compartment 17, an open vegetable compartment air outlet 37b is formed. The vegetable compartment air outlet 37b communicates with the blowing side of the cooling fan 23 via the vegetable compartment air blowing passage 37 and the openable and closable vegetable compartment damper 37a. The vegetable compartment air outlet 37b serves as an entrance when the air blown out by the cooling fan 23 flows into the vegetable compartment 17. Further, in the vegetable compartment 17, an open vegetable compartment return air port 38a is formed. The vegetable compartment return air port 38a communicates with the cooling chamber 20 via the vegetable compartment return air duct 38. For this reason, the air blown out by the cooling fan 23 flows into the vegetable compartment 17 via the vegetable compartment damper 37a, the vegetable compartment air blowing duct 37, and the vegetable compartment air outlet 37b, and then returns to the cooling chamber 20 via the vegetable compartment return air port 38a and the vegetable compartment return air duct 38.

[0028] In the freezer compartment 19, an open freezer compartment air outlet 39b is formed. The freezer compartment air outlet 39b communicates with the blowing side of the cooling fan 23 via the freezer compartment air blowing duct 39. The freezer compartment air outlet 39b serves as an entrance when the air blown out by the cooling fan 23 flows into the freezer compartment 19.

[0029] [1-1-2. Configuration of Wiring Connection] FIG. 4 is a rear view showing the refrigerator compartment duct 31 in the refrigerator 1. FIG. 5 is a perspective view showing the refrigerator compartment duct 31. As shown in FIG. 3, a refrigerator compartment duct 31 is provided on the rear side of the refrigerator compartment 11. As shown in FIGS. 4 and 5, the refrigerator compartment duct 31 includes a duct support member 40. The duct support member 40 includes a base portion 41 whose lower end portion extends in the left-right direction, and a duct support portion 42 that extends above the base portion 41 along the rear surface of the refrigerator compartment 11. The upper part of the duct support portion 42 has a shape that is bent forward and then rises upward in accordance with the inner surface shape of the refrigerator compartment.

[0030] A duct main body 43 is provided on the rear surface side of the duct support portion 42. The duct main body 43 has a substantially U-shaped cross-sectional shape, and by being attached to the duct support member 40, a duct air passage 44 is formed between the duct support member 40 and the duct main body 43. The duct support member 40 is formed with a plurality of air outlets 31b according to the space partitioned by the shelf board in the refrigerating chamber.

[0031] FIG. 6 is a perspective view showing a boundary portion between the refrigerating chamber 11 and the partial chamber 11a. FIG. 7 is a perspective view showing a state in which the lower tray of the refrigerating chamber is closed at the boundary portion between the refrigerating chamber 11 and the partial chamber 11a. As shown in FIG. 6, tray support rails 50 extending in the front-rear direction are provided on both side surfaces of the boundary portion between the refrigerating chamber 11 and the partial chamber 11a. Above the tray support rail 50, a tray peripheral covering portion 51 is provided with a predetermined gap from the tray support rail 50. Above the tray support rail 50, a lower tray 52 of the refrigerating chamber is provided so as to be slidable in the front-rear direction.

[0032] Then, in a state where the lower tray 52 of the refrigerating chamber is installed at the innermost part along the tray support rail 50, the upper sides of both side edges and the upper side of the rear edge of the lower tray 52 of the refrigerating chamber are covered by the tray peripheral covering portion 51, and the refrigerating chamber 11 and the partial chamber 11a are configured to be partitioned without a gap. As shown in FIGS. 4 and 5, a duct-side connector housing portion 60 is provided at one end of the base portion 41 of the duct support member 40. The duct-side connector housing portion 60 is formed in a substantially box shape, and a duct-side opening 61 as an opening is formed on the upper surface of the duct-side connector housing portion 60.

[0033] FIG. 8 is a perspective view showing a part of the refrigerating chamber. FIG. 9 is a cross-sectional view of the connector housing portion. FIG. 10 is a perspective view of the state where the lower tray 52 of the refrigerating chamber is closed. FIG. 11 is a perspective view of the lower tray 52 portion of the refrigerating chamber. As shown in FIGS. 8, 9, and 11, inside the duct-side connector housing portion 60, for example, predetermined electrical and electronic components and connection terminals for wiring from a temperature sensor that detects the internal temperature of the refrigerating chamber are housed. Specifically, the connection connector 65 of the refrigerating chamber temperature sensor 62, the connection connector 65 of the partial chamber temperature sensor 63, the connection connector 65 of the partial chamber lighting 64, etc. are housed.

[0034] As shown in FIG. 8, a refrigerator-side connector housing portion 70 is provided at a position corresponding to the duct-side connector housing portion 60 of the refrigerator compartment. The refrigerator-side connector housing portion 70 is arranged so as to be close to the tray support rail 50, and the upper end surface of the refrigerator-side connector housing portion 70 is located slightly below the upper end surface of the tray support rail 50. The refrigerator-side connector housing portion 70 is formed in a substantially rectangular frame shape, and a refrigerator-side opening 71 as an opening is formed on the front side of the refrigerator-side connector housing portion 70. As shown in FIG. 6, the refrigerator-side connector housing portion 70 is arranged inside the duct-side connector housing portion 60, and is configured such that other surfaces except the upper surface side are covered by the duct-side connector housing portion 60. Inside the refrigerator-side connector housing portion 70, a connection connector 72 connected to a control circuit board (not shown) of the refrigerator and the like is housed.

[0035] With the duct-side connector housing portion 60 arranged outside the refrigerator-side connector housing portion 70, the duct-side opening 61 of the duct-side connector housing portion 60 and the refrigerator-side opening 71 of the refrigerator-side connector housing portion 70 are arranged to overlap. In this way, it is possible to connect the connection connector 72 of the refrigerator-side connector housing portion 70 and the connection connector 65 of the duct-side connector housing portion 60 through the refrigerator-side opening 71 of the refrigerator-side connector housing portion 70 and the duct-side opening 61 of the duct-side connector housing portion 60. Then, as shown in FIGS. 7 and 10, with the lower refrigerator tray 52 placed on the tray support rail 50 and slid to the rearmost position, the upper surfaces of the refrigerator-side connector housing portion 70 and the duct-side connector housing portion 60 are configured to be covered by the lower refrigerator tray 52. In FIG. 10, the refrigerator-side connector housing portion 70 and the duct-side connector housing portion 60 are shown by broken lines.

[0036] [1-2. Operations, etc.] Next, the operation of the refrigerator in the first embodiment will be described. In the present embodiment, as shown in FIGS. 9 and 10, the connection connector 72 of the refrigerator compartment side connector housing portion 70 and the connection connector 65 of the duct side connector housing portion 60 are connected through the refrigerator compartment side opening 71 of the refrigerator compartment side connector housing portion 70 and the duct side opening 61 of the duct side connector housing portion 60. The refrigerator compartment side opening 71 and the duct side opening 61 facilitate the connection work of the respective connection connectors 65 and 72.

[0037] Thereafter, as shown in FIG. 7, the lower refrigerator compartment tray 52 is placed on the tray support rail 50 and slid to the rearmost position. In this state, the upper surfaces of the refrigerator compartment side connector housing portion 70 and the duct side connector housing portion 60 are covered by the lower refrigerator compartment tray 52. Thereby, even if the upper surfaces of the refrigerator compartment side connector housing portion 70 and the duct side connector housing portion 60 are opened by the refrigerator compartment side opening 71 and the duct side opening 61, the refrigerator compartment side opening 71 and the duct side opening 61 can be covered by the lower refrigerator compartment tray 52. Therefore, after connecting the connection connectors 65 and 72, it is not necessary to close the refrigerator compartment side opening 71 of the refrigerator compartment side connector housing portion 70 and the duct side opening 61 of the duct side connector housing portion 60 with a separate member.

[0038] [1-3. Effects, etc.] As described above, in the present embodiment, a refrigerator compartment and a refrigerator compartment duct 31 that sends cold air to the refrigerator compartment are provided. The refrigerator compartment includes a refrigerator compartment side connector housing portion 70 and a duct side connector housing portion 60 (connector housing portions) that house the connection connector 65 of the refrigerator compartment duct 31 and the connection connector 72 of the refrigerator compartment. The refrigerator compartment side connector housing portion 70 and the duct side connector housing portion 60 have a refrigerator compartment side opening 71 and a duct side opening 61 (openings) on their upper surfaces, and the refrigerator compartment side opening 71 and the duct side opening 61 are closed by a lower refrigerator compartment tray 52 (shelf board) installed in the refrigerator compartment. As a result, even if the upper surfaces of the refrigerator-side connector housing portion 70 and the duct-side connector housing portion 60 are opened by the refrigerator-side opening 71 and the duct-side opening 61, the refrigerator lower tray 52 can cover the refrigerator-side opening 71 and the duct-side opening 61. Therefore, after connecting the connection connectors 65 and 72, it is not necessary to close the refrigerator-side opening 71 of the refrigerator-side connector housing portion 70 and the duct-side opening 61 of the duct-side connector housing portion 60 with separate members, and the number of components can be reduced.

[0039] Also, in the present embodiment, the connector housing portion is composed of a refrigerator-side connector housing portion 70 that houses the connection connector 72 of the refrigerator main body, and a duct-side connector housing portion 60 that houses the connection connector 65 of the refrigerator duct 31 and covers the refrigerator-side connector housing portion 70. The connection connector 72 of the refrigerator and the connection connector 65 of the refrigerator duct 31 can be connected via the refrigerator-side opening 71 and the duct-side opening 61 (openings). Thereby, the connection connector 72 of the refrigerator-side connector housing portion 70 and the connection connector 65 of the duct-side connector housing portion 60 can be connected via the refrigerator-side opening 71 of the refrigerator-side connector housing portion 70 and the duct-side opening 61 of the duct-side connector housing portion 60. Therefore, the connection work of each connection connector 65 and 72 can be easily performed by the refrigerator-side opening 71 and the duct-side opening 61.

[0040] Also, in the present embodiment, the shelf board is the refrigerator lower tray 52 that partitions the refrigerator compartment and the partial compartment, and the duct-side connector housing portion 60 houses the connection connector 65 from the refrigerator compartment and the partial compartment. As a result, in the refrigerator-side connector housing portion 70 and the duct-side connector housing portion 60, the duct-side connection connector 65 and the partial-compartment-side connection connector 65 and the refrigerator-side connection connector 72 can be easily connected.

[0041] In the present embodiment, the refrigerator compartment side connector housing portion 70 and the duct side connector housing portion 60 (connector housing portions) are arranged in the vicinity of the lower surface side of the refrigerator compartment lower tray 52 (shelf board). As a result, the vicinity of the refrigerator compartment side opening 71 of the refrigerator compartment side connector housing portion 70 and the duct side opening 61 of the duct side connector housing portion 60 can be blocked by the refrigerator compartment lower tray 52. Therefore, it is possible to suppress the intrusion of foreign matter into the refrigerator compartment side connector housing portion 70 and the duct side connector housing portion 60.
