[0018] The technical solution of the present application will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0019] The components of the embodiments of the present application generally described and shown in the accompanying drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the application claimed, but merely represents the selected embodiments of the present application.

[0020] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0021] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0022] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0023] Refer to the following Figure 1-Figure 6 A direct cooling refrigerator freezer compartment controller structure is described according to some embodiments of the present application.

[0024] In refrigerators or freezers that use direct cooling technology, the controller needs to be installed on the inner wall of the refrigerator or freezer with screws. Since the space in the freezer is relatively small, the controller in the freezer has simple functions and is therefore small in size. During production and assembly, one way is for the installer to hold the controller housing with one hand and use the other hand to operate the tool to complete the screw connection between the controller and the inner wall of the refrigerator; another way is to turn the refrigerator body upside down, operate the tool to complete the screw connection between the controller and the inner wall of the refrigerator, and then restore it, which is very inconvenient.

[0025] A direct cooling refrigerator freezer compartment controller structure comprises a fixing base 1 and a bottom shell 2, wherein the fixing base 1 is arranged at the top wall corner of the freezer compartment, a controller assembly is arranged in an inner cavity formed by the connection between the bottom shell 2 and the fixing base 1, the fixing base 1 is provided with a pair of downwardly convex screw seats 3, the bottom shell 2 is provided with a screw column 4 corresponding to the screw seat 3, a sleeve 5 extends from the top of the screw column 4, and during installation, the sleeve 5 of the screw column 4 is aligned with the screw seat 3 and inserted therein, since the inner hole of the sleeve 5 and the outer edge of the screw seat 3 are interference fit, the bottom shell 2 is clamped by the fixing base 1 after being connected to the fixing base 1 and will not fall off by itself, and the installer does not need to use his hands to support the bottom shell, and can conveniently complete the screw connection between the bottom shell 2 and the fixing base 1, thereby realizing the stable installation of the controller on the inner wall of the refrigerator.

[0026] The horizontal side of the rear opening of the bottom shell 2 is provided with an outwardly protruding wire groove 6, and the wire groove 6 protrudes obliquely upward along the horizontal side of the rear opening of the bottom shell 2. During installation, the redundant wires of the controller assembly will be guided by the wire groove 6 and gathered in the inner cavity formed by the connection between the bottom shell 2 and the fixing seat 1, so as to avoid the wires being pressed in the connecting gap between the bottom shell 2 and the fixing seat 1 during installation, causing damage to the wires and affecting the sealing; at the same time, the wire groove 6 protrudes obliquely upward along the horizontal side of the rear opening of the bottom shell 2, which can also make it easier to complete the installation close to the inner wall of the freezer compartment when the bottom shell 2 and the fixing seat 1 are installed.

[0027] In order to ensure the temperature control effect, a thermostat box 7 is used to place the thermostat. The thermostat box 7 includes a box body 8 and a box cover 9. The box cover 9 covers the opening of the box body 8. An outer retaining ring 10 is extended from the outer edge of the inner side of the box cover 9, and inner retaining rings 11 are extended from the four corners of the inner side of the box cover 9. When the box cover 9 is covered with the box body 8, the inner retaining ring 11 is in contact with the inner wall of the box body 8, and the outer retaining ring 10 is in contact with the outer wall of the box body 8, thereby achieving good sealing of the thermostat box 7 and avoiding frost caused by excessive contact of the thermostat with cold air, which affects the temperature control effect. The inner retaining ring 11 is fin-shaped, so that the box cover 9 has a certain degree of guidance when the box body 8 is covered, and the installation efficiency is high.

[0028] A card slot 12 is provided on the inner side of the outer retaining ring 10, and a buckle 13 corresponding to the card slot 12 is provided on the outer side of the opening edge of the box body 8. When the box cover 9 is closed with the box body 8, the buckle 13 and the card slot 12 are buckled with each other, so that the box cover 9 and the box body 8 can be stably closed and maintain good sealing.

[0029] The box cover 9 is provided with a threading hole 14, and the wires of the thermostat enter and exit through the threading hole 14. It is only necessary to add necessary sealing protection to the threading hole 14 to avoid damaging the sealing of the thermostat box 7 due to an overly large wiring opening.

[0030] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
