Description

  The present invention relates to a refrigerator provided with a condensation prevention heater.

  Generally, a refrigerator has a storage room for storing stored items inside an inner box of a refrigerator main body consisting of an outer box and an inner box, and a door is attached to an opening for taking in and out the stored items. In this way, cool air is sent into the storage room for cooling. The door of the opening is provided with a gasket all around its inner surface to ensure hermeticity when the door is closed.

In this refrigerator, with the opening and closing of the door, condensation may occur on the gasket due to the difference between the inside temperature and the outside air temperature around the installation location. For this reason, a conventional anti-condensation heater is attached to the periphery of the opening of the refrigerator body where the gasket abuts, and the anti-condensation heater is energized to generate heat, and the heat is used to heat the gasket to prevent condensation. (Patent Document 1).
Japanese Patent Laid-Open No. 5-240565

  In the above refrigerator, when attaching a dew condensation prevention heater to the periphery of the opening of the refrigerator body with which the gasket of the heat insulating door comes into contact, for example, as shown in FIG. 9, the outer box of the refrigerator body comprising an outer box 40 and an inner box 41 An anti-condensation heater 43 is attached by using an adhesive tape 44 at a position where the gasket 48 of the heat insulating door 47 that opens and closes via the hinge 49 is inside the front side wall member 42 of 40. After that, the outer box 40 was fitted into the inner box 41 in which the resin cover 46 was previously inserted, and the heat insulating material was filled between the boxes 40 and 41.

  However, if the attachment position of the heater 43 for condensation prevention is closer to the outside of the warehouse than the contact position of the gasket 48 of the heat insulating door 47 (close to the side wall of the outer box 40), the heater for preventing condensation is attached to the gasket 48. The heat of 43 becomes difficult to be transmitted, and there is a possibility that condensation occurs on the gasket 48. On the other hand, if the mounting position is closer to the inside of the cabinet (near the side wall of the inner box 41), condensation of the gasket 48 can be prevented, but the heat of the condensation prevention heater 43 is easily transmitted to the interior of the cabinet. The internal temperature rises, and the power consumption for cooling the interior increases.

  As described above, the heater 43 for preventing condensation has to be attached at a predetermined position with respect to the contact position of the gasket 48 of the heat insulating door 47. For this reason, the attachment work using the adhesive tape 44 is not only difficult to position, but also difficult to attach the dew condensation prevention heater 43 in parallel with the gasket 48, which requires a lot of time.

  The lead wire 45 for supplying electricity to the dew condensation prevention heater 43 is attached to the inner side of the side wall of the outer box 40 by an adhesive tape 44 (see FIG. 9). Since it is not attached, it is attached at an arbitrary position for each product. Since the mounting position of the lead wire is not specified, there is a risk that the lead wire 45 may be accidentally damaged or cut when a mounting hole for a part such as a handle is provided on the side wall of the outer box 40.

  Accordingly, an object of the present invention is to improve the workability of attaching the dew condensation prevention heater to the peripheral edge of the opening of the refrigerator main body, and to reliably attach the dew condensation prevention heater to a position where the dew condensation is efficiently prevented by the heat generation. .

  In order to solve the above-mentioned problems, in the present invention, a contact portion with the door at the periphery of the opening of the refrigerator main body is formed by a cover fitted in the refrigerator main body, and a condensation prevention heater is attached to the cover in advance. I did it.

  A dew condensation prevention heater can be attached to the cover before being fitted to the opening peripheral edge of the refrigerator main body in a wide space. For this reason, the dew condensation prevention heater can be easily mounted at an appropriate position of the cover, and when the cover with the dew condensation prevention heater mounted at an appropriate position is fitted to the opening peripheral edge of the refrigerator body, The heater is attached to a predetermined position (appropriate position) with respect to the contact portion of the cover with the door.

  In the present invention, as described above, since the cover is fitted, the dew condensation prevention heater is attached to a predetermined position of the contact portion with the door of the opening peripheral portion of the refrigerator main body. The installation workability of the heater for preventing condensation on the surface is improved.

  An embodiment of the present invention is a refrigerator in which a dew condensation prevention heater is provided at the periphery of the opening of the refrigerator body to which the door is attached so as to be freely opened and closed, and the contact portion of the opening periphery of the refrigerator body with the door is The cover may be formed by a cover fitted to the refrigerator body, and the cover may be preinstalled with the dew condensation prevention heater.

  In this configuration, the cover can be made of a material that forms the inner and outer walls of the refrigerator body, such as stainless steel, but synthetic resin can also be used because of its good moldability. In this case, a gasket is provided on the entire periphery of the contact portion of the door with the periphery of the opening of the refrigerator body, and the magnet is provided on one of the gasket and the contact portion of the periphery of the opening of the refrigerator body with the door. In a refrigerator in which a magnetic body is provided and the gasket is adhered to the periphery of the opening of the refrigerator main body by adsorption of the magnetic body of the magnet, since the resin is not adsorbable to the magnet, the opening of the refrigerator main body When the magnet is provided in the gasket, the magnet is provided in the resin cover portion that is in contact with the peripheral door, and the magnet is provided in the case where the magnetic material is provided in the gasket.

  In this case, as the magnet and the magnetic body, not only the plate piece but also those obtained by mixing those powders in the resin cover or the gasket can be adopted.

  Further, if the cover is made of a synthetic resin, it can be easily molded, and a mounting portion for a dew condensation prevention heater, a groove for fitting a lead wire, and the like can be easily molded.

  The refrigerator body is provided with an inner box in an outer box, and the cover is in contact with the door and the sheet metal of the outer box that forms the periphery of the opening of the refrigerator body. A configuration having a heater pressing piece that reliably contacts the dew condensation prevention heater can be employed. If it does in this way, the heater for dew condensation is hold | maintained in the state which contacted the sheet metal of the outer box which forms the contact part with the door of a cover, and the opening part periphery of the said refrigerator main body.

  Further, the opening of the refrigerator body is partitioned by a partition bar, and includes a door that opens and closes each of the partitioned openings, and the contact part of the partition bar with the door is fitted to the partition bar. The structure formed by the cover can be employed. According to this configuration, the dew condensation prevention heater can be easily attached to the contact portion with the door of the partition bar that defines the opening of the refrigerator main body.

  In the case of this refrigerator, if the side part of the cover against which the partition bar abuts is made of a soft material that exhibits a sealing effect, the partition bar is attached to the opening of the refrigerator main body, thereby forming the soft side part of the cover. The material is deformed, and the gap between the partition bar and the side surface of the cover fitted around the periphery of the opening of the refrigerator body is reliably filled. If this gap is filled, the sealing work conventionally performed to fill this gap can be omitted.

  This sealing structure with a soft material can also be employed in the abutting surface portion between the cover and the opening-side end surface portion of the door side wall material of the refrigerator main body. That is, the abutting surface portion of the cover can be a soft material that exhibits a sealing effect. In this way, the cover is fitted to the periphery of the opening of the refrigerator body, and the cover is abutted against the refrigerator body, so that the soft material forming the abutment surface is deformed and the contact portion with the cover door And the gap between the opening and the peripheral edge of the refrigerator body are securely filled. If this gap is filled, the sealing work conventionally performed to fill this gap can be omitted.

  If the power supply line to the dew condensation prevention heater is attached to the cover in advance, the power supply line is positioned by fitting the cover, so that the power supply line is accidentally damaged or cut. Can be prevented.

  One embodiment of the present invention is shown in FIGS. In the refrigerator of this embodiment, as shown in FIGS. 1A and 1B, the refrigerator main body 1 is partitioned into a plurality of storage rooms 3 by partition bars 2, and has a handle 4 on the front surface of each storage room 3. The heat insulating door 5 is attached in a double-spread type. A dew condensation prevention heater 6 for preventing dew condensation is provided on the periphery of the opening of each warehouse 3, and a gasket 7 for sealing a gap with the refrigerator main body 1 is provided around the back surface of each heat insulating door 5.

  The refrigerator body 1 includes an outer box 8 and an inner box 9, and a heat insulating material 10 such as urethane is filled between the boxes 8 and 9. The outer box 8 and the inner box 9 may be made of a stainless steel plate. An opening for taking in and out stored items is formed on the front surface of the refrigerator body 1, and a storage room 3 for keeping the stored items is formed in the inner box 9.

  A unit base (not shown) provided with a refrigeration cycle is disposed at the top of the refrigerator body 1, and cold air from the refrigeration cycle is sent into the respective compartments 3. A plurality of support legs 12 are attached to the lower surface of the refrigerator main body 1, and the refrigerator main body 1 is supported on the floor surface.

  As shown in FIG. 3, the front side wall member 14 forming a part of the outer box 8 of the refrigerator main body 1 is bent at the opening end of the side wall 13 of the outer box 8 and is orthogonal to the side wall of the inner box 9. It extends in the direction and reaches the middle part up to the inner box 9. An opening side wall member 15 that is bent toward the back side in parallel with the side wall 13 of the outer box 8 is formed at the front end portion of the front side wall member 14. Further, an opening-side bent portion 16 is formed which is bent at the rear side end portion of the opening side wall member 15 and extends in a direction orthogonal to the side wall of the inner box 9.

  As shown in FIGS. 2 and 3, a resin cover 20 is fitted to the periphery of the opening of the refrigerator body 1 at the contact portion with the heat insulating door 5. The resin cover 20 is made of synthetic resin, and has a front plate part 21 connected to the front side wall member 14 of the outer box 8 and a side plate part orthogonal to the front member 21 and connected to the side wall of the inner box 9. 22 and an L-shaped cross section. Since the resin cover 20 is made of a synthetic resin, it is easy to mold, and a latching portion 24 that latches to a heater holding portion 23 to which a dew condensation prevention heater 6 to be described later is attached or an opening-side bent portion 16 of the outer box 8 is secured. In addition, the groove 25 and the like for fitting the lead wire 17 can be easily formed.

  As shown in FIG. 3, the front plate portion 21 of the resin cover 20 has a heater holding portion 23 extending toward the back side of the refrigerator main body 1, and continues to the holding portion 23 toward the side wall 13 of the outer box 8. It has the latching | locking part 24 extended, and the groove | channel 25 which fits the lead wire 17 which supplies electricity to the heater 6 for anti-condensation. The front plate portion 21 has the magnet 18 embedded therein, and the front plate portion 21 in which the magnet 18 is embedded comes into contact with the gasket 7 of the heat insulating door 5 provided with a magnetic body and adsorbs to each other by an adsorption action by magnetic force.

  When the gasket 7 is provided with a magnet, a magnetic body is embedded in the front plate portion 21 of the resin cover 20. The magnet and the magnetic body can adopt not only a mode consisting of plate pieces, but also a mode in which iron powder (magnet powder) is mixed into the gasket 7 or the resin cover 20. In short, the front plate portion 21 of the resin cover 20 and the gasket are used. Any mode may be used as long as 7 and 7 are mutually adsorbed by an adsorption action by magnetic force.

  Further, the abutting surface portion 32 of the front plate portion 21 of the resin cover 20 and the opening sidewall material 15 of the outer box 8 of the refrigerator body 1 is formed of a soft synthetic resin material that exhibits a sealing effect. Since the abutting surface portion 32 is formed of a soft synthetic resin material, when the resin cover 20 is fitted, the synthetic resin material is compressed and deformed, and the opening side wall material 15 of the outer box 8 and the resin cover 20 are compressed. The gap generated between the front plate portion 21 and the front plate portion 21 is securely filled. If this gap is filled, a sealing operation for filling this gap to be performed in a later process can be omitted.

  The heater holding portion 23 of the front plate portion 21 is formed with a heater pressing piece 26 and a heater support piece 27 extending toward the side wall 13 of the outer box 8. The heater pressing piece 26 is formed by being bent toward the front side of the refrigerator main body 1 while extending toward the side wall 13 of the outer box 8 from a portion near the locking portion 24. The heater support piece 27 is formed to extend from a portion near the front plate portion 21 toward a bent portion of the heater pressing piece 26.

  The heater holding portion 23 presses the dew condensation prevention heater 6 against the back surface of the front plate portion 21 with the heater holding piece 26, and the dew condensation prevention heater 6 is in contact with the front plate portion 21 with the heater support piece 27. To support. In this way, the heater holder 6 can be used to attach the dew condensation prevention heater 6 in contact with the magnetic body (magnet) 18 of the front plate 21. As a result, the dew condensation prevention heater 6 is energized to generate heat, the magnetic material (magnet) 18 of the front plate 21 is heated by the heat generated, and the gasket 7 of the door 5 that contacts the front plate 21. To prevent condensation.

  In addition, since the resin cover 20 is made of a synthetic resin, its thermal conductivity is smaller than that of the stainless steel plate outer box 8 and inner box 9. The movement of heat between the inner side and the outer side of the front plate part 21 is suppressed, and the front plate part 21 on the outer side of the box is hardly cooled by the cool air inside the box. If the front plate portion 21 is less likely to be cooled, the amount of heat generated by heating the dew condensation prevention heater 6 can be suppressed, and an increase in the internal temperature due to heat from the dew condensation prevention heater 6 can be minimized. .

  As shown in FIG. 4, the condensation prevention heater 6 is attached in advance to the heater holding portion 23 of the resin cover 20, so that the condensation prevention is achieved by fitting the resin cover 20 to the opening peripheral edge of the refrigerator body 1. The heater 6 is attached to a predetermined position of a contact portion (front plate portion 21) of the resin cover 20 with the door 5 (see FIG. 3). If it does in this way, before assembling the refrigerator main body 1, it becomes unnecessary to fix the heater for dew condensation inside the opening peripheral part of the refrigerator main body 1 with a tape. Thus, by inserting the resin cover 20 attached with the outer box 8 into the inner box 9 placed with the opening facing upward in advance, the refrigerator body 1 is manufactured, so that the dew condensation prevention heater 6 is brought into a predetermined position. Since it is attached, the attachment work of the dew condensation prevention heater 6 can be easily performed.

  Further, the locking portion 24 of the resin cover 20 includes a protrusion 28 protruding toward the front plate portion 21 and a claw 29 formed at the tip. When the resin cover 20 is fitted to the front side wall member 14 of the outer box 8, the opening side bent portion 16 of the outer box 8 is formed by the protrusion 28 of the locking portion 24 and the bent portion of the heater pressing piece 26. The nail | claw 29 is caught by the opening side wall material 15 of the said outer box 8 by being pinched. In this way, the front side wall member 14 of the outer box 8 and the front plate portion 21 of the resin cover 20 are abutted without any step.

  At this time, the dew condensation prevention heater 6 held by the heater holding portion 23 of the resin cover 20 reliably contacts the sheet metal (opening side wall material 15) of the outer box 8 by the action of the heater pressing piece 26 and the heater support piece 27. To do. As a result, the heat of the dew condensation prevention heater 6 is transmitted not only to the magnetic body (magnet) 18 of the front plate portion 21 of the resin cover 20 but also to the front side wall member 14 of the outer box 8, thereby efficiently preventing dew condensation. can do.

  In addition, a recessed portion 30 that is thin may be formed in a connecting portion between the heater holding portion 23 and the locking portion 24 of the resin cover 20. With this recess 30, the heater holding portion 23 and the locking portion 24 can be elastically deformed in the front-rear direction with respect to the refrigerator body 1. Thereby, when fitting the resin cover 20, as shown in FIG. 4, the latching | locking part 24 can be opened and elastically deformed, and it can be easily fitted in the opening side bending part 16 of the outer box 8. FIG.

  Furthermore, the lead wire 17 is held in the resin cover 20 by fitting the lead wire 17 into the groove 25 of the resin cover 20 (see FIG. 4). When the resin cover 20 holding the lead wires 17 is fitted to the opening peripheral edge portion of the refrigerator main body 1, the lead wires 17 are attached to the contact portion (front plate portion 21) of the resin cover 20 with the door 5. Thereby, it becomes unnecessary to fix the lead wire 17 with the tape inside the opening peripheral part of the refrigerator main body 1, and the attachment operation | work of the lead wire 17 can be performed easily. Furthermore, since the lead wire 17 is positioned, when the mounting hole for parts such as a handle is provided in the side wall 13 of the outer box 8 as in the prior art, the lead wire 17 may be accidentally damaged or cut. Can be prevented.

  The side plate portion 22 of the resin cover 20 is provided with a pressing piece 31 having elasticity inside the end portion. When the side wall of the inner box 9 is inserted between the side plate portion 22 of the resin cover 20 and the pressing piece 31, the pressing piece 31 presses the side wall of the inner box 9 against the side plate portion 22 of the resin cover 20, The side wall of the inner box 9 and the resin cover 20 are connected.

  As shown in FIG. 3, the side plate portion 22 of the resin cover 20 fitted to the left and right peripheral edges of the opening of the refrigerator main body 1 exhibits a sealing effect at the abutting portion with the horizontal rail 2 b of the partition rail 2 described later. Formed of a soft synthetic resin. As shown in FIG. 2, when the horizontal rail 2 b is attached to the periphery of the opening of the refrigerator main body 1, the abutting portion 33 is deformed by the soft synthetic resin material and the side plate portion 22 and the horizontal rail of the resin cover 20. The gap generated between 2b is filled. If this gap is filled, the sealing work for filling the gap in the subsequent process can be omitted. As shown in FIG. 5, the abutting portion 33 may be one in which a soft synthetic resin material is fixed in advance to the side plate portion 22 of the resin cover 20. Even in this case, when the horizontal rail 2b is attached to the periphery of the opening of the refrigerator body 1, the abutting portion 33 is deformed, so that the gap between the side plate portion 22 of the resin cover 20 and the horizontal rail 2b is reliably filled. (See FIG. 6).

  On the other hand, as shown in FIG. 7, the side plate portion 22 of the resin cover 20 fitted to the upper and lower peripheral edges of the opening of the refrigerator body 1 has a sealing effect at the abutting portion with the vertical beam 2 a of the partition beam 2 described later. It is formed of a soft synthetic resin material that exhibits As shown in FIG. 2, when the horizontal rail 2 b is attached to the periphery of the opening of the refrigerator main body 1, the abutting portion 33 is deformed by the soft synthetic resin material and the side plate portion 22 and the horizontal rail of the resin cover 20. The gap generated between 2b is surely filled. Note that this abutting portion 33 may also be one in which a soft synthetic resin material is fixed in advance to the side plate portion 22 of the resin cover 20 in the same manner as the abutting portion 33 described above.

  The resin cover 20 is also fitted to the partition bar 2 that partitions the opening of the refrigerator body 1. As shown in FIG. 2, the partition beam 2 is composed of a vertical beam 2a and two horizontal beams 2b. The vertical beam 2a divides the opening of the refrigerator main body 1 into left and right, and the two horizontal beams 2b.

As shown in FIG. 8, the front plate portion 21 of each resin cover 20a is connected to the front plate 19 of the vertical beam 2a, and the side plate portion 22a is fitted to the side wall of the rear cover 35 of the vertical beam 2a. Here, each resin cover 20a is different in the structure of the side plate 22a from the side plate 22 of the resin cover 20 fitted to the periphery of the opening of the refrigerator body 1, and the other structure is the same as the resin cover 20. It is. That is, the side plate portion 22a is formed with a claw 36 that engages with the side wall of the back cover 35 and a concave portion 37 that houses a fixing screw.

  The front plate 19 of the vertical beam 2a is formed with a bent portion 34 in which both ends thereof are bent toward the back and outward each other. The engaging portion 24 of the resin cover 20 is fitted into the bent portion 34, and the front plate portion 21 of the resin cover 20 and the front plate 19 of the vertical rail 2a are connected without any step. Further, the side wall of the vertical beam 2a is inserted between the side plate portion of the resin cover 20 and the pressing piece 31, and the resin cover 20 is fitted to the vertical beam 2a.

  At this time, the dew condensation prevention heater 6 held by the heater holding portion 23 of the resin cover 20 contacts the bent portion 34 of the front plate 19 of the vertical rail 2a. Thereby, the heat of the dew condensation prevention heater 6 is transmitted not only to the front plate portion 21 of the resin cover 20 but also to the front plate 19 of the vertical rail 2a, so that the occurrence of dew condensation can be efficiently prevented.

  Moreover, the mounting structure of the resin cover 20 of the horizontal beam 2b of the partition beam 2 is the same as the mounting structure of the vertical beam 2a described above. That is, the resin cover 20 is fitted to the contact portion of the horizontal rail 2b with the door 5.

  As shown in FIG. 8, the side plate portion 22 of the resin cover 20 fitted to the vertical beam 2a is formed by a soft synthetic resin whose abutting portion with the horizontal beam 2b exhibits a sealing effect. . As shown in FIG. 2, the abutting portion 33 is deformed to fill a gap generated between the side plate portion 22 of the resin cover 20 and the horizontal rail 2 b when the horizontal rail 2 b is attached. The abutting portion 33 is also fixed in advance with a soft synthetic resin material on the side plate portion 22 of the resin cover 20 in the same manner as the abutting portion 33 of the resin cover 20 fitted to the periphery of the opening of the refrigerator body 1 described above. It may be what you did.

  The vertical rail 2a and the horizontal rail 2b hold the condensation prevention heater 6 at the contact portion (the front plate portion 21 of the resin cover) with the door 5 in the same manner as the peripheral edge of the opening of the refrigerator body 1 described above. ing. For this reason, it is not necessary to fix the dew condensation prevention heater with the tape inside the vertical beam 2a and the horizontal beam 2b, and the attachment work of the dew condensation prevention heater 6 can be easily performed.
