Description

Combined refrigerator

技术领域 Technical field

The present invention relates to the field of refrigeration equipment, and more particularly to a combined refrigerator.

背景技术 Background technique

In order to maintain the freshness of the food, refrigerated or frozen storage cabinets are used in shopping malls and homes. With the development of the market and the improvement of living standards, people are increasingly demanding large-volume refrigerators. Because the needs of different consumers are different, each family's eating habits and food storage habits vary widely, even in different seasons or different periods, which requires different products while increasing the volume of the refrigerator. Many functions, and different function modules can be independently controlled and used separately.

However, the super-large-volume refrigerator has high manufacturing cost, large mold investment, serious product deformation problem, strict manufacturing requirements, and long production cycle. One common method is to manufacture each module unit separately, and then assemble and splicing to form a combination. Refrigerator products. The Chinese Patent Office has published a number of related patents for box splicing combinations ( CN102980345A , CN200950957Y , CN1184924A , CN2397456Y ), by combining at least two cabinet units to form a combined refrigeration and / Or the freezing system, each box unit is relatively independent, and can be separately controlled and transported separately. However, some of these combinations require that the cabinet unit be assembled in the outer cabinet, and the bottom surface of the box body is provided with a guide strip matching the guide groove of the outer cabinet (other than that without other support structure), so that the single storage cabinet cannot be Independent of the use of the outer cabinet, it is also not conducive to separate sales, such as patent applications CN102980345A . Some need to install several cabinet units on a condenser mounting plate and a compressor mounting plate and connect their circuit systems in parallel, resulting in a single cabinet unit not being used alone or sold separately. Moreover, if a cabinet unit fails, it is necessary to replace the entire condenser mounting plate or the compressor mounting plate, which is inconvenient to operate, such as a patent application. CN200950957Y. CN2397456Y The patented combination is achieved by mating the bumps on the bottom of the freezer case with the recesses on the top of the freezer and then fastening them with bolts. Since the structure for the splicing assembly (bumps, pits) is provided on the box unit, it is disadvantageous for individual sales. CN1184924A Patent The published method of operation is to supply power to the combined cooling system through an external power supply. Each refrigeration unit cannot be used separately after being disassembled. Moreover, the cabinet structures of the left, middle and right refrigeration units involved in this combination are not completely identical (mainly embodied on the left and right side wall structures of the cabinet) and cannot be sold separately.

When multiple modular units are spliced into a large-volume refrigerator, it is usually required that the door opening angle does not exceed 90 ° in order not to affect the normal use of each module. The interior trim or item can still be easily accessed or replaced. The Chinese Patent Office has published several related technical solutions, among which CN202947411U patent Through the structural design and cooperation of the door attachment (bottle) and the cabinet attachment (drawer), 90 ° door opening is achieved, that is, the bottle holder on the door body and the drawer in the box body are completely dislocated in the height direction, when the door body is opened Angle is 90 ° When there is a gap between the inner surface of the door and the running track of the drawer, the drawer can be pulled out of the box without any trouble. CN201757560U Patent A support strip is arranged on the inner side wall of the tank, and a front support portion and a rear portion of the rear support avoiding the notch portion of the tank support strip are arranged on both sides of the shelf, and the 90 ° door opening is realized by the arrangement and cooperation of the shelf and the tank structure. CN1487255A Patent The shelf support shaft is arranged on the side of the tank to protrude into the storage compartment for loading the shelf. Since the support shaft can be received into the tank, when the door opening angle is less than 90 ° The shelf height can also be adjusted. However, the above method requires that the cabinet, the door body and related interior parts (such as the shelf / shelf / bottle holder / The structure of the drawer) makes the design flexibility of the product unsatisfactory; and the matching of the relevant components is required, and the requirements for design, assembly, and manufacturing are high, and the cost of the mold is expensive. When there is a requirement for the product volume, or it is necessary to introduce other accessories in the box, or when the cabinet and / When the door body has process manufacturing problems, it is difficult to change the component structure or product design input to ensure the 90 ° door opening, which is not conducive to product performance optimization or product expansion and modification.

具体实施方式 detailed description

The invention will be further described in detail below with reference to the drawings and specific embodiments.

Example 1

1. The splicing combination of two cabinet units is a combination door refrigerator

As shown in Figure 1, two cabinet units are placed side by side, with the left freezer unit 2 For the left door opening method (the door hinge is located on the left side of the box), the right side freezer unit 1 is the right door opening method (the door hinge is located on the right side of the box). The combination box unit is a freezer - freezer or a freezer - freezer or freezer - Freezer, the two are spliced together to form a large-volume, multi-function door-to-door combination refrigerator.

The two cabinet units of the splicing combination should have the same height (the longitudinal distance from the bottom to the top of the cabinet) and the depth (the distance from the front end of the refrigerator door to the rear end of the cabinet), and the color, door panel and other appearances are basically the same. The width of the cabinet (the spacing between the left and right side panels of the cabinet) may be the same or different according to the design requirements.

Each of the above-mentioned combined refrigerators has an independent compressor, a refrigeration system, a circuit system, and a matching accessory system, which are completely independent of each other and do not interfere with each other. The power cables are separated from each other. One power supply corresponds to one cabinet unit. When using, the corresponding power cables can be connected. Each box unit can be controlled separately, and one or two of them can be selected to be turned on or off according to need; if one fault requires power failure repair or replacement, it does not affect the use of another box unit, thus facilitating the housing unit. Reuse, upgrade, repair, and disassembly, recycling, and disposal after disposal.

As shown in Figure 2, the height and depth of the box unit must be adjusted flush before splicing: with adjustable feet 3 Move the cabinet back and forth to align it in the depth direction; then rotate the adjustable foot 3 to raise the box (clockwise) or lower (counterclockwise) so that the two are level.

The components used in the splicing combination box unit are shown in Figures 3 to 9, one of which is connected to the block 4 Installed on the corresponding screw hole on the back of the cabinet unit, that is, the upper left corner or upper right corner of the compressor compartment 11, and the other upper connecting block 4 is installed at the corresponding screw hole at the top, that is, the left or right side of the top cover 12; Connection block 6 Installed on the corresponding screw hole in the lower part of the front of the cabinet unit (the intersection of the left or right lower front beam and the side panel), the lower connecting block cover 7 is assembled on the lower connecting block 6;

screws

5, 8, 9 They are installed on the top, back and front lower part of the box unit respectively to fasten and combine the box unit. The assembly process is shown in Figure 10.

As shown in Fig. 11, in order to realize the seamless integral splicing effect, the connecting strip 10 is inserted into the splicing box unit side panel 13 In the gap between them, the top end is flush with the top cover 12, and the end is flush with the lower connection block cover 7.

The following describes the opening and closing of the combined refrigerator door and the 90 ° door opening:

When the box units are spliced and combined, in order not to affect the normal use of each box unit, it is generally required that the door body of each box unit can be smoothly opened or closed without interfering with the adjacent box unit, and in the door body 90 ° When you open it, you can still access or replace the box interior parts or items. To achieve this, the present invention achieves the above requirements by reasonably setting the upper and lower hinge mounting positions of the door body, as follows.

The center of the door hinge A is close to the side of the door casing, and the horizontal distance L1 between the center of the door hinge A and the lowest point of the arc of the door shell (door hinge side) B ( 16.6 mm) does not exceed the horizontal distance L2 (17.5 mm) between the center of the door hinge A and the side panel 13 of the cabinet unit. In addition, in order not to cause the door seal fitting problem, the door hinge center A Set inside the door seal face 14, as shown in Figure 12.

During the opening and closing process of the combined refrigerator cabinet unit door, point E (door hinge side door arc surface center D and door hinge center A The intersection of the extension line of the point line and the arc surface is the farthest point in the horizontal direction of the trajectory of the door hinge side door, which determines the minimum distance L4 (horizontal direction) between two adjacent door bodies. When AD When the connection and the center of the door unit hinge A A ' are coincident (the door opening angle is about 59 °), the horizontal distance L4 of the adjacent two doors (door hinge side) reaches the minimum value (7.8 mm). ), but still larger than the two-box splicing combination spacing L0 (5.0 mm), as shown in Figure 13. As shown in the figure, it can be ensured that when one box unit opens the door, it does not interfere with the adjacent box unit body and affects the opening and closing of the door body, which is beneficial to the realization of the subsequent multiple box splicing combination.

When the combination refrigerator unit door is opened at 90 °, the cabinet interior is like a drawer (15 or 15) ') Close to the door body and the corresponding position at the refrigerated door liner 16 or the freezer door liner 16 'the highest surface still has a certain gap (L5 = 5.9 mm, L5 ' = 12.8 mm), as shown As shown in Figure 14, it is possible to smoothly access or replace interior items such as drawers or items stored in the box.

In addition, due to the horizontal distance between the center of the door hinge A and the highest point of the arc of the door shell (middle of the door) C, L3 (27 mm) ) is larger than the horizontal distance L2 (17.5 mm) between it and the side panel 13 of the cabinet unit, with a difference of 9.5 mm between them. When the combined refrigerator is placed against the wall and the refrigerator unit 1 Or the horizontal distance L6 between the freezer unit 2 (side panel) and the wall 17 is very small (such as 10 mm), there is still a certain gap between the highest point C of the door shell end face and the wall 17, and the cabinet unit can still 90 ° open the door body and can freely pick up the box interior parts or items, does not affect the normal use of the combined refrigerator, as shown in Figure 15 As shown, it solves the problem that the large-volume refrigerator takes up a large space and the position of the cabinet is placed (that is, a wider cabinet-wall spacing is required).

Example 2

2, two cabinet units are combined side by side into a left-to-the-door combination refrigerator.

And embodiment 1 The combination of the door opening methods is similar. The two box units are placed side by side. When the left and right box units are left-opening, the two are combined to form a multi-functional left-to-door combination refrigerator. Figure 16 As shown, the two freezer compartment units 2 are joined side by side.

Example 3

3, two cabinet units are combined side by side into a right-to-same door combination refrigerator.

And embodiment 1 The combination of the door opening modes is similar. The two box units are placed side by side. When the left and right box units are right-opening, the two are combined to form a multi-function right-to-door refrigerator. 17 As shown, the two refrigerated cabinet units 1 are joined side by side.

Example 4

4, two cabinet units are combined side by side as a back-to-door combination refrigerator.

And embodiment 1 The combination of the door opening methods is similar, and the two box units are placed side by side. When the left box unit is the right door opening mode and the right box unit is the left door opening mode, the two are combined to form a multifunctional back direction. Same as the door refrigerator, as shown in Figure 18. As shown, the reefer unit 1 on the left side and the freezer unit 2 on the right side are joined together side by side.

Example 5

5. Three or more cabinet units are combined side by side to open the door to the left side - the door combination refrigerator.

Three cabinet units are combined side by side to open the door to the left side - the effect of the split door combination refrigerator is shown in Figure 19, with two freezer compartment units from the left and the middle 2 and one freezer unit on the right 1 Side by side. The number of cabinet units may also be three or more as needed. Correspondingly, the number of the box connection components is also increased, and the combination thereof may be any combination between the refrigerator and the freezer.

Similar to the splicing combination of two cabinet units, these cabinet units should have the same height and depth, the color, door panel and other appearance effects are basically the same, and the cabinet width can be the same or different according to design requirements.

In summary, the present invention can combine a plurality of cabinet units into a large-volume, multi-functional refrigerator according to different preferences or different functions of the customer, thereby realizing the user's personalized operation selection of the refrigerator function.

It should be noted that the combined refrigerator is not limited to the splicing between single door cabinet units, but also can be single door - multiple doors, or multiple doors - The splicing combination between the multi-door box units only requires the height and depth of the refrigerating box unit to be uniform, and the 90° door opening can be realized by the method described in the present invention.

In addition, since each cabinet unit has independent compressor, refrigeration system and circuit system, it can be designed separately and manufactured separately. It has complete appearance and complete independence. It can be packaged separately as a refrigerator or freezer, sold separately, and separately repaired. ,Use alone. The user can purchase the refrigerated box unit or the freezer unit separately according to the requirements, or perform any combination of splicing and combination to realize a large-volume, multi-functional combination refrigerator product to meet the individual needs and usage habits of different users.
