JP, 2013-177991, A

  In the case of connecting the wiring members with a connector in a refrigerator, it is necessary to prevent condensation on the connector portion, that is, the portion where the conductor may be exposed, from the viewpoint of safety. In that case, for example, a measure may be taken to cover the connector using a bag-like member.

  Now, in the case where the connector is covered with a bag-like member, it is necessary to provide a support structure or the like in which the opening is surely directed downward in order to prevent condensation water from being accumulated in the member. If it is structured, workability will deteriorate. Therefore, conventionally, a structure in which the connector is embedded in the wall portion of the storage chamber or a structure in which the recess is provided in the storage chamber and disposed therein, that is, a countermeasure for preventing exposure in the storage chamber is taken.

  However, in the structure in which the connector is embedded in the wall portion or the recess is provided, it is necessary to secure the structure and space for embedding the connector, and there is a problem that the storage amount is reduced. In addition to the need for a fixing operation such as embedding and fixing because the connector is connected and then embedded in the wall and fixed in the recess, it is properly connected after performing the fixing operation, In addition, it is necessary to check whether the connector is properly covered, which causes a problem that the workability is reduced.

  Therefore, a refrigerator is provided that can prevent condensation of the connector with a simple structure and a structure with excellent workability.

  The refrigerator according to the embodiment includes a storage chamber formed of a resin material, a connector for electrically connecting an electrical component stored in the storage chamber, and a protective member for covering the connector together with the wiring member. The protection member is provided in a state of being exposed from the upper wall portion of the chamber into the storage chamber, and the protection member is made of a resin material and is attached to the sheet member and the sheet member in which the first through hole through which the connector penetrates is formed. And the sheet member is pasted to the upper wall portion in a state where the connector penetrates with the plate member, and the sheet member is attached to the outer periphery of the plate member. The side part covers the connector together with a part of the wiring member connected to the connector.

Hereinafter, embodiments will be described with reference to the drawings.
As shown in FIG. 1, in the refrigerator 1 of the present embodiment, the refrigerator compartment 2 and the vegetable compartment 3, which are storage compartments of the refrigeration temperature zone, are arranged below the vegetable compartment 3 in order from the upper side An ice making chamber 4 and an upper freezing chamber 5 and a lower freezing chamber 6 located at the lowermost stage of the refrigerator 1 are provided. In addition, the number and the position of each storage room are an example, and are not limited to this.

  In the refrigerator 1, a machine room 7 is provided on the lower back side. A compressor or the like (not shown) is disposed in the machine room 7. Further, a storage room 8 for storing electrical components and the like is provided above the machine room 7 and on the back side of the upper freezing room 5 in the present embodiment. In addition, arrangement | positioning of the storage chamber 8 is an example, It is not limited to this.

  In the case of the present embodiment, the storage room 8, that is, the inner box of the refrigerator 1 is formed of a flammable resin material. The storage chamber 8 accommodates a cooler 9 which constitutes an evaporator of a refrigeration cycle. Although not shown, the cooler 9 is provided with a temperature sensor for detecting the temperature of the cooler 9, a defrost heater for defrosting the cooler 9 by electric heating, or an electric component such as a blower fan. It is done. Therefore, in the storage chamber 8, the connector 10 for connecting the wiring member 12 (see FIG. 2) of the electrical component is exposed in the storage chamber 8 from the upper wall 8a (see FIG. 2) of the storage chamber 8. Provided in

  FIG. 2 schematically shows the storage room 8 viewed from the front side of the refrigerator 1. As described above, the cooler 9 is provided in the storage chamber 8, and the wiring member 12 of the electrical component extends from the cooler 9 side. A connector 11 for connecting to the connector 10 is provided at the end of the wiring member 12. Thus, the connector 10 and the connector 11 are connected in the storage chamber 8.

  Now, as described above, when the wiring member 12 is connected by the connectors 10 and 11 in the refrigerator 1, it is necessary to prevent condensation on the connector portion from the viewpoint of safety. In that case, for example, although it is conceivable to cover the connectors 10 and 11 using a bag-like member, it is necessary to provide a support structure or the like in which the opening is surely directed downward to prevent condensation water from being accumulated in the member. There is.

  However, in the structure in which the connectors 10 and 11 are embedded in the wall portion of the storage chamber 8 and fixed in the recess, it is necessary to secure the structure and space for embedding the connectors 10 and 11 and the storage capacity is reduced. become. Also, in addition to the need for a fixing operation of embedding and fixing in the wall after connecting the connectors 10 and 11, whether they are properly connected at the stage after the fixing operation, or in the form of a bag There is also a problem that the workability is lowered because it is necessary to further confirm whether the connectors 10 and 11 are properly covered with the above components.

  In addition, in order to prevent the spread of fire to other parts if connectors 10 and 11 are abnormally overheated by any chance, it is necessary to use a flame retardant material, but in that case the cost will increase. . That is, it is one of the big problems of the refrigerator 1 of this embodiment to suppress the spread of fire to other parts even if the connectors 10 and 11 overheat abnormally by any chance.

  Therefore, in the present embodiment, as shown in FIG. 3, a protective member 13 is provided which is attached to the upper wall 8 a of the storage chamber 8 and covers the connectors 10 and 11 together with the wiring member 12. As shown in FIG. 4, the protection member 13 is provided on the sheet member 20, the plate member 21, the back side of the sheet member 20 in the plane of the drawing, and affixes the sheet member 20 to the upper wall 8 a. The double-sided adhesive tape 23 is provided on the front side of the sheet surface of FIG. Each member is disposed so that the plate member 21 is located within the range of the double-sided tape 22 and the double-sided tape 23 is located within the range of the plate member 21.

  The sheet member 20 is formed of a resin material, which is polyethylene in the present embodiment, in the form of an octagonal sheet as shown in FIG. Further, a through hole 20 a is formed in the central portion of the sheet member 20. The diameter (R) of the through hole 20a is formed so that the connector 10 can pass therethrough. The through hole 20a corresponds to a first through hole. In addition, the shape of the sheet | seat member 20 is an example, and is not limited to this.

  The sheet member 20 is formed to be larger in outer shape than the plate member 21. More specifically, the sheet member 20 is formed in a size capable of covering the connectors 10 and 11 and a part of the wiring member 12 as described later.

  The plate member 21 is formed of a metal material, in this embodiment, stainless steel. As shown in FIG. 6, the plate member 21 is formed in a square having a side L1 and chamfered corner portions, and a through hole 21a through which the connector 10 can penetrate is formed at the central portion thereof. It is formed. The through hole 21 a corresponds to a second through hole. Further, the through holes 21 a are formed in such a shape and size that the connector 10 can penetrate while sliding.

  Therefore, the plate member 21 is fixed to the connector 10 when the connector 10 penetrates the through hole 21 a. The through holes 21 a are formed by punching out in a direction indicated by the arrow X with a press or the like. Therefore, although it is slight, a burr may occur on the lower surface 21b on the lower side in the drawing.

  As shown in FIG. 7, the double-sided adhesive tape 22 is formed in a square having a side L2 and chamfered corners. At this time, the length (L3) of one side of the double-sided tape 22 is formed longer than the length (L1) of one side of the plate member 21. The double-sided tape 22 may be formed into a shape other than a square, as long as it is larger than the plate member 21.

  Further, in the central portion of the double-sided adhesive tape 22, a through hole 22a formed to a size capable of penetrating the connector 10 is formed. The through hole 22a is formed in a rectangular shape with one side L4 and L5. In addition, it may have a square which is L4 = L5. The length (L4, L5) of one side of the through hole 22a is longer than the width (L2, L3) of one of the outer edge portions of the through hole 21a of the plate member 21. Therefore, the double-sided tape 22 does not contact the connector 10 directly.

  The double-sided tape 23 is formed in a square having a side L6 and chamfered corners. At this time, the length (L6) of one side of the double-sided tape 22 is formed shorter than the length (L1) of one side of the plate member 21. However, the double-sided tape 23 can be formed into a shape other than a square, as long as it is smaller than the plate member 21.

  Further, in the central portion of the double-sided adhesive tape 22, a through hole 23a formed to a size capable of penetrating the connector 10 is formed. The through hole 23a is formed in a rectangular shape with one side L4 and L5. In addition, it may have a square which is L4 = L5. The length (L4, L5) of one side of the through hole 23a is longer than the width (L2, L3) of one of the outer edge portions of the through hole 21a of the plate member 21. Therefore, the double-sided tape 22 does not contact the connector 10 directly.

  The protection member 13 having such a configuration is provided in a state in which the plate member 21 is substantially fixed to the connector 10 and in a state in which the protection member 13 is attached to the upper wall portion 8a by the double-sided tape 22 as shown in FIG. . Then, in a state in which a part of the sheet member 20 formed larger than the plate member 21 outside the plate member 21 covers the connectors 10 and 11 and a part of the wiring member 12 connected thereto, the binding band It is tied in the state of being squeezed like a tea ceremony by 30.

  At this time, as shown in FIG. 9, since the double-sided tape 22 for attaching the sheet member 20 has a larger external shape than the plate member 21, the end portion where the sheet member 20 is free from the upper wall 8a and metal There is a gap (W1) between the end of the plate member 21 and the end of the plate member 21 so that the sheet member 20 and the plate member 21 do not come in direct contact with each other. Further, the plate member 21 is disposed so that the lower surface 21b where burrs may occur is directed to the lower side in the drawing, that is, the opposite side to the double-sided tape 23. Therefore, the risk of the sheet member 20 and the double-sided tape 23 being damaged by the burrs is reduced. The distance (S1) can be set to about several millimeters, for example, about 5 millimeters.

  Since the protective member 13 having such a configuration entirely covers the connectors 10 and 11, even if the insulating coating of the wiring member 12 is peeled off in the connectors 10 and 11, in other words, the metal of the wiring member 12 Even when the conductor is exposed, adhesion of water can be prevented. Moreover, since it is a structure attached to the upper wall part 8a and squeezing the lower side, even if dew condensation arises in the protection member 13, dew condensation water will be discharged from the lower end side.

According to the refrigerator 1 described above, the following effects can be obtained.
The refrigerator 1 includes a storage chamber 8 formed of a resin material, connectors 10 and 11 electrically connecting electrical components stored in the storage chamber, and a protection member 13 covering the connectors 10 and 11 together with the wiring member 12; Is equipped. Then, the protection member 13 is formed of a resin material, and is attached to the sheet member 20 in which the first through hole 20a through which the connector 10 penetrates is formed and the sheet member 20, and the second through which the connector 10 penetrates. The sheet member 20 is attached to the upper wall portion 8 a in a state where the connector 10 penetrates with the plate member 21, and the sheet member 20 is attached to the outer peripheral side of the plate member 21. The part that covers the connectors 10 and 11 together with a part of the wiring member 12.

  In this case, since the protective member 13 entirely covers the connectors 10 and 11, adhesion of water to the connectors 10 and 11 can be prevented. Further, since the protective member 13 is attached to the upper wall portion 8a and the lower side is bound, even if dew condensation occurs in the protective member 13, it is possible to discharge the dew condensation water from the lower end side.

  Therefore, since the connector 10 can be provided in a state exposed in the storage chamber 8, a space for housing the connector 10 and a structure for supporting the protective member 13 become unnecessary, so the storage capacity of the refrigerator 1 is reduced. Not cause

  Further, the protective member 13 can be attached only by being attached to the upper wall portion 8a, and does not get in the way during the operation of housing the cooler 9 and the electrical components. Furthermore, when the housing operation is completed, the wiring operation can be performed as it is, and after that, the connectors 10 and 11 and the wiring member 12 can be protected by simply bundling them with the binding band 30, thus greatly improving the working efficiency. Can.

  Therefore, dew condensation of the connector can be prevented with a simple structure and a structure excellent in workability. In other words, the connectors 10 and 11 can be used for the refrigerator 1.

  Further, the plate member 21 is formed in such a shape that the second through hole 21a can slide on the connector 10, and the sheet member 20 can be fixed to the connector 10, so that the risk of the protective member 13 falling off is reduced. can do.

  The plate member 21 is formed of a metal material. Thereby, even if connector 10 overheats abnormally, since it can control fire spread with plate member 21, safety at the time of using a connector in refrigerator 1 can be improved. Therefore, even if the sheet member 20 is not formed of a flame-retardant material, the possibility of spreading fire to other members when the connector abnormally generates heat can be reduced.

The embodiment described above can be appropriately modified without departing from the scope of the invention.
Although the sheet member 20 is formed of polyethylene in the embodiment, it is not excluded to form the sheet member 20 of a flame retardant material. That is, the sheet member 20 may be formed of a flame-retardant material instead of a resin material as long as the sheet member 20 has flexibility to wrap the connector 10 and the like. Thus, the possibility of spreading fire due to abnormal heat generation or the like of the connector portion can be further reduced.

  In the embodiment, an example in which the outer shape of the sheet member 20 is octagonal is shown, but it may be other shape. For example, if the outer shape is circular, it is considered that the above-mentioned extra portion is minimized. However, since the outer shape of the sheet member 20 also relates to the efficiency of the number of sheets taken out from one base material, taking into consideration the efficiency of the number of sheets taken, for example, a shape such as a plane filling hexagonal It can also be done.

The protective member 3 may be configured to be attached with an adhesive instead of the double-sided tapes 22 and 23. Moreover, it can also be set as the structure which uses a double-sided tape and an adhesive agent together.
The plate member 21 can also be formed of a metal material other than stainless steel. Even in that case, the spread of fire can be suppressed.
In the embodiment, a temperature sensor, a defrost heater, a blower fan and the like are shown as the electrical components, but the type and number of the electrical components are not limited to this.

  Although the storage room 8 which stores the cooler 9 is shown in the embodiment, the machine room 7 is also included in the storage room. That is, as long as the storage chamber 8 is a section in which electrical components are stored, such as the upper rear surface of the refrigerator 1, for example, those other than those described in the embodiment are included. In other words, the protective member 13 can be applied to any portion where a connector connection is required.

  Each embodiment is presented as an example and is not intended to limit the scope of the invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the scope of the invention. The present embodiment and the modifications thereof are included in the scope and spirit of the invention, and are included in the invention described in the claims and the equivalents thereof.
