[0024] Please see Figure 1 , Figure 5 and Figure 6 This utility model provides a technical solution: a refrigerator with an external compressor, including an outdoor condensing unit 1, a freezer cabinet 3, and a touch screen control cabinet 4, wherein the outdoor condensing unit 1, the touch screen control cabinet 4, and the freezer cabinet 3 are arranged sequentially from right to left. Inside the outdoor condensing unit 1, a compressor 101 and a condenser 102 are installed sequentially from bottom to top. The compressor 101 is used to compress a low-temperature, low-pressure gaseous refrigerant into a high-temperature, high-pressure gas, driving the refrigerant to circulate. The condenser 102 is used to condense and release the high-temperature, high-pressure gaseous refrigerant. The refrigerant is a room-temperature, high-pressure liquid. An evaporator 10 is installed at the bottom of the inner side of the freezer 3. The evaporator 10 is used to evaporate the low-temperature, low-pressure liquid refrigerant and absorb heat from the space being cooled. A box 9 is set above the evaporator 10 at the bottom of the inner side of the freezer 3. The box 9 is used to support the items. The output end of the compressor 101 is fixedly connected to the input end of the condenser 102. The output end of the condenser 102 is fixedly connected to the input end of the evaporator 10. The output end of the evaporator 10 is fixedly connected to the input end of the compressor 101.

[0025] Specifically, the compressor 101 is turned on, and the freezer 3 is cooled by the cooperation of the condenser 102 and the evaporator 10, so as to quickly freeze the finished or semi-finished cream puffs, thereby locking in the structure, moisture and flavor of the cream puffs.

[0026] The built-in unit was replaced with an external condensing unit, so that the entire heat dissipation process is completed outdoors, saving space and energy consumption. The original manual button and knob start-up was replaced with touch screen control cabinet 4 control start-up, realizing one control of multiple units. Combined cooling conditions can be set according to different items, making it more intelligent, visual and simpler for employees to operate.

[0027] exist Figure 1 and Figure 3 In the middle: The rear end of the outdoor condensing unit 1 is symmetrically provided with a rear cover 2. The rear cover 2 is used to close the maintenance port. The rear cover 2 and the outdoor condensing unit 1 are rotatably connected by a support shaft 5. A torsion spring 6 is provided between the rear cover 2 and the outdoor condensing unit 1 on the outside of the support shaft 5. The torsion spring 6 is used to make the rear cover 2 automatically spring open.

[0028] Specifically, since the rear cover 2 is rotatably connected to the outdoor condensing unit 1 through the support shaft 5 and is also connected through the torsion spring 6, the rear cover 2 will automatically pop open under the action of the torsion spring 6 and remain perpendicular to the outdoor condensing unit 1.

[0029] exist Figure 2 and Figure 4 In the middle: A locking mechanism 7 is provided at the top of the inner side of the outdoor condensing unit 1 to facilitate the inspection and maintenance of the outdoor condensing unit 1. The locking mechanism 7 includes a locking plate 701 located inside the rear cover 2 and a buckle plate 702 movably connected to the outdoor condensing unit 1. When the locking plate 701 and the buckle plate 702 are engaged, they are used to position the rear cover 2. The buckle plate 702 is rotatably connected to the outdoor condensing unit 1 through a rotating shaft 703. The side of the buckle plate 702 away from the locking plate 701 is connected to the movable plate 704.

[0030] Specifically, when the movable frame 706 slides horizontally outward, since the movable frame 706 and the movable plate 704 are slidably connected through the guide groove 705, and the buckle plate 702 is rotatably connected to the outdoor condensing unit 1 through the rotating shaft 703, the movable plate 704 and the buckle plate 702 deflect around the rotating shaft 703 and separate from the locking plate 701. Then the rear cover 2 can be opened to allow for inspection and maintenance of the interior of the outdoor condensing unit 1.

[0031] exist Figure 2 and Figure 4 In the middle: the ends of both the locking plate 701 and the buckle plate 702 are set as beveled structures.

[0032] Specifically, after the maintenance is completed, the rear cover 2 is pushed towards the outdoor condensing unit 1, causing it to deflect around the support shaft 5. During this process, since the closer ends of the locking plate 701 and the buckle plate 702 are inclined, the inclined surface of one end of the locking plate 701 slides along the inclined surface of one end of the buckle plate 702 and pushes the buckle plate 702 to deflect around the axis of the rotating shaft 703 until the locking plate 701 and the buckle plate 702 are engaged.

[0033] exist Figure 2 and Figure 4 In the middle: A guide groove 705 is provided on the side of the movable plate 704 away from the buckle plate 702. A movable groove is provided at the top of the inner side of the outdoor condensing unit 1. A movable frame 706 is slidably connected inside the movable groove. When the movable frame 706 moves laterally, it is used to deflect the movable plate 704 and the buckle plate 702. The movable frame 706 includes a straight plate and L-shaped rods symmetrically arranged at the bottom of the straight plate. The L-shaped rods and the movable plate 704 form a sliding structure through the guide groove 705.

[0034] Specifically, when the movable frame 706 slides outward horizontally, the buckle plate 702 and the movable plate 704 can be deflected around the pivot 703 under the limiting action of the guide groove 705.

[0035] exist Figure 2 and Figure 4 In the middle: A return spring 707 is connected between the movable frame 706 and the movable slot. The return spring 707 is used to make the movable frame 706 automatically return to its original position. A lifting rod 708 is provided on one side of the movable frame 706, which passes through the return spring 707 and the outdoor condensing unit 1. The lifting rod 708 is used to make the movable frame 706 move laterally. The lifting rod 708 consists of a straight rod and a pull ring on one side of the straight rod.

[0036] Specifically, by pulling the lifting rod 708 outward, the movable frame 706 slides horizontally outward, and the return spring 707 contracts under force. When the lifting rod 708 is released, the lifting rod 708 and the movable frame 706 will automatically return to their original positions under the action of the return spring 707.

[0037] exist Figure 2 and Figure 4 In the middle: The top of the inner side of the outdoor condensing unit 1 is symmetrically provided with baffles 8 between the two buckle plates 702. The baffles 8 are used to prevent the buckle plates 702 from deflecting towards the locking plate 701.

[0038] Specifically, the buckle plate 702 is limited by the stop bar 8 to prevent the buckle plate 702 from deflecting towards the lock plate 701.

[0039] The compressor 101 is turned on, and the freezer 3 is cooled by the cooperation of the condenser 102 and the evaporator 10, so as to quickly freeze the finished or semi-finished cream puffs, thereby locking in the structure, moisture and flavor of the cream puffs.

[0040] When maintenance is required on the outdoor condensing unit 1, the movable frame 706 slides horizontally outward by pulling the lifting rod 708 outward, causing the return spring 707 to contract under force. Through the sliding action between the movable frame 706 and the movable plate 704, and the rotational action between the latch plate 702 and the outdoor condensing unit 1, the movable plate 704 and the latch plate 702 deflect about the pivot 703 and separate from the locking plate 701. Simultaneously, through the rotational action of the rear cover 2 and the outdoor condensing unit 1, and the elastic return mechanism... The function is such that the rear cover 2 will automatically pop open under the action of the torsion spring 6 and remain perpendicular to the outdoor condensing unit 1, which facilitates the inspection and maintenance of the interior of the outdoor condensing unit 1. After the inspection and maintenance is completed, the rear cover 2 is pushed towards the outdoor condensing unit 1, causing it to deflect around the support shaft 5. During this process, the inclined surface of one end of the locking plate 701 slides along the inclined surface of one end of the buckle plate 702 and pushes the buckle plate 702 to deflect around the axis of the rotating shaft 703 until the locking plate 701 and the buckle plate 702 are fastened together.

[0041] Electrical equipment (including but not limited to motors, electric actuators, etc.) is safely powered by an external power source and controlled by a control box. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0042] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
