Definitions

• the present invention relates to a refrigerator in a household appliance, and more particularly to a horizontal refrigerator with a drawer.
• ZL92236971. 2 discloses this type of refrigerator, which sets the horizontal refrigerator into upper and lower freezer compartments. Each floor can have one or more freezer compartments.
• the upper freezer compartment has a top opening and an openable lid. Closed; the lower freezer has a built-in drawer that can be pulled out for easy access.
• the compressor of the refrigerator is located near the side wall of the refrigerator to occupy as little space as possible. Because the prior art does not further disclose the structure of the freezer, especially the structure of the cabinet, the arrangement of the evaporator, and the setting of the drawer sliding device, there is no specific teaching, so there is no way to talk about the optimization of its structure, so it is separated from commercial development and utilization. There is still some distance.
• a carriage assembly is generally used.
• the assembly includes an inner carriage and an outer carriage.
• the outer carriages are guide rails directly installed on both sides of the cabinet, which are easily deformed and cause difficult positioning.
• the sliding resistance is large, and it is not easy to mass-produce at the same time.
• the invention aims at overcoming the shortcomings of the prior art, and provides a novel freezer structure, which is simple in process, can reasonably allocate the space between the freezer compartments, and advances so that the drawer in the lower freezer compartment has a relatively stable slide Structure for easy installation and Support, thereby improving production efficiency.
• the present invention provides a horizontal cold heading with a drawer, comprising: a frame body, which defines an upper freezing chamber and at least one lower freezing chamber, and the upper freezing chamber and the lower freezing chamber are separated by a partition. Open, with the upper freezer opening upwards and the lower freezer opening horizontally; a top cover connected to the top of the cabinet for sealingly covering the opening of the upper freezer compartment; A drawer in a freezer compartment; at least a part of an evaporator buried in the cabinet, the cabinet including a pre-formed upper front plate, a rear plate, and two side plates, the upper front plate being connected with the two side plates of the cabinet, and a sliding frame
• the assembly includes an outer carriage and an inner carriage.
• the outer carriage has longitudinal rails located on both sides of the cabinet and a front crossbar and a rear crossbar between the two rails, wherein the front crossbar is fixed to the partition. on.
• the rear cross bar is fixed on the rear wall of the inner shell of the lower freezer compartment of the cabinet.
• the integrally formed enclosure board in the prior art is divided into two side boards and a front board, and the front board and the two side boards are separated during pre-forming, which can be processed through conventional processes and is easy to assemble Reduced manufacturing costs.
• the fixing structure of the carriage assembly used for the extension has also been improved.
• the outer carriage in the carriage assembly has a frame structure.
• the outer carriage is fixed to the partition wall and the inner wall of the carcass through the front and rear crossbars between the guide rails, instead of directly fixing the two guide rails to the left and right of the cabinet. Both sides ensure accurate cooperation with the inner carriage.
• the evaporator arranged in the refractory body is divided into a coil part and a plate tube part, wherein the coil part is buried in the wall of the cabinet, and the plate tube part is exposed on the upper part of the lower freezing compartment .
• the coil part and the tube part are connected together by a connector in the lower freezer.
• the evaporator Since the evaporator is composed of a coil part in the upper freezing compartment and a tube part in the lower freezing compartment, and the two parts are connected by a connector, the coil part and the tube part can be processed separately.
• the connection of the evaporator parts of the upper and lower freezer compartments is by welding, and it needs to be welded together in advance, which will cause the evaporator to be oversized, inconvenient to handle, and difficult to guarantee the welding quality.
• Figure 1 is a front view of a horizontal freezer of the Emperor drawer according to the present invention
• 2 is a longitudinal sectional view of the refrigerator shown in FIG. 1, in which a top cover, a condenser and a compressor are not cut;
• FIG. 3 is a sectional view taken along line A-A in FIG. 1;
• FIG. 4 is a partially enlarged view of a region B in FIG. 3; FIG.
• FIG. 5 is a perspective view of the carriage assembly shown in FIG. 2;
• FIG. 6 is a schematic structural diagram of an evaporator used in the present invention.
• the cold rejection is generally represented by reference numeral 1 and includes a rejection body 8 which defines an upper freezing compartment 22 and a lower freezing compartment 21, and the upper freezing compartment 22 and the lower freezing compartment 21 are separated by a partition 10 minutes.
• the opening of the upper freezing compartment 22 faces upward, and the opening of the lower freezing compartment 21 faces sideways.
• a top cover 2 is connected to the top of the cabinet 8 (for example, by a hinge) to cover the opening of the upper freezing chamber in a sealed manner.
• the top cover 2 may be made of, for example, a foam material, or may be made of a transparent or translucent material.
• a drawer 19 is installed in the lower freezer compartment 21.
• Drawer 19 is through a carriage assembly
• the carriage 18 is mounted to the lower freezer compartment, and the carriage assembly 18 is composed of an inner carriage 18a and an outer carriage 18b, see FIG. 5. As can be seen from the figure, the inner carriage 18b is mounted on the drawer 19, and the outer carriage is fixed on the cabinet 8. The inner carriage 18a can slide in a pair of rails 18b-1, 18b-2 of the outer carriage 18b. .
• the outer carriage 18b is a frame structure, which includes a pair of longitudinally extending guide rails 18b-1 and 18b-2.
• a forward crossbar 18b-4 and a rear crossbar 18b-3 are connected between the pair of guide rails, wherein the front crossbar 18b-4 is fixed on the partition plate 10, and the rear cross bar 18b-3 is fixed on the rear wall of the inner liner 5 of the lower freezing chamber 21.
• the cabinet 8 is generally composed of an outer plate and an inner plate and a filling material between the outer plate and the inner plate.
• the outer plate includes an upper front plate 4, two side plates 15 and a rear plate 13, and the upper front plate 4 is connected by welding or plugging, for example. It is connected to the two side plates 15 in the manner described above. Please refer to part B of FIG. 3 and its enlarged view, FIG. 4. In this embodiment, a welding method is adopted, and FIG. 4 shows one of the welding seams.
• the upper front panel 4 connected to the two side panels 15 is flush with the panel 6 of the drawer 19.
• the panel 6 may also be made of a transparent, translucent or opaque material.
• An evaporator 12 is also shown in FIG. 2 and includes 22 weeks of placement in the upper freezer compartment.
• the surrounding upper evaporator portion 12 is located between the outer plate and the inner liner 3 and the lower evaporator portion 16 is located in the lower freezer compartment 21.
• the upper evaporator is placed between the outer plate 2 and the inner tank 3 before the foaming agent is injected, and the lower evaporator portion is directly exposed to the lower freezing chamber 21.
• the upper evaporator 12 is a coiled evaporator
• the lower evaporator 16 is a plate and tube evaporator
