Description

Technical Field

[0001] The utility model relates to the technical field of ice makers, in particular to an installation structure of an ice-making component. Background Art

[0002] At present, for the granular ice maker on the market, its core component is a sealed cavity with an ice-making tubular structure. The water in the sealed cavity is turned into ice by refrigerant, and then a spiral structure on a scraping ice rod scrapes the ice on the inner wall structure of the ice-making tube, and the ice is pushed out from the shaper to complete the ice-making process.

[0003] For example, an evaporator for an ice maker disclosed in Chinese Patent CN112484345A includes a cylinder body and a spiral push rod arranged in the cylinder body. The cylinder body includes an inner tube and an outer tube sleeved outside the inner tube and closing the upper and lower ends of the inner tube. The bottom end of the inner tube is connected with a water inlet pipe and a drain pipe. The top end of the inner tube forms an ice outlet hole. A cavity for accommodating refrigerant is formed between the outer tube and the inner tube. The upper and lower ends of the outer tube are respectively connected with a refrigerant outlet pipe and a refrigerant inlet pipe.

[0004] In the above prior art, the cylinder body is fixedly installed on the motor housing. The spiral push rod for scraping ice is connected to the output shaft of the motor through a reduction mechanism. During the process of squeezing the ice, the spiral push rod will generate a downward axial force, and the load formed by this force is directly applied to the connection part between the cylinder body and the motor housing. The connection part needs to be strengthened in design to ensure the structural and connection strength, resulting in a relatively high structural cost.

[0005] Therefore, the prior art still needs to be improved and developed. Content of the Utility Model

[0006] The purpose of the utility model is to provide an installation structure of an ice-making component with reasonable structure, low cost and convenient cleaning in view of the defects and deficiencies of the prior art.

[0007] In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows:

[0008] An installation structure of an ice-making component according to the present utility model includes a motor, an ice-making bucket, and a scraping screw. The scraping screw is rotatably arranged in the ice-making bucket. A bucket seat is fixedly provided at the lower end of the ice-making bucket. The lower end of the scraping screw passes through the bucket seat and is rotatably connected thereto. The bucket seat is placed on the housing of the motor. The housing is circumferentially cooperatively connected with the bucket seat. The output shaft of the motor is drivingly connected to the lower end of the scraping screw. The ice-making bucket, the bucket seat, and the scraping screw form an ice-making component. By placing the bucket seat on the housing of the motor, the housing of the motor only bears the weight of this component. The bucket seat and the housing cannot rotate relative to each other, so that the motor can drive the scraping screw to rotate in the ice-making bucket through the output shaft. The scraping screw extrudes the ice cubes in the ice-making bucket, generating a downward axial force. This axial force is applied to the bucket seat and transmitted to the ice-making bucket. At the same time, the upward pushing of the ice cubes will also generate an upward axial force on the ice-making bucket. The two forces cancel each other out and will not generate a working load on the motor and the housing, thereby simplifying the structural design of the ice maker and reducing the production cost.

[0009] According to the above solution, a central through hole is provided on the bucket seat. A first shaft sleeve is provided in the upper port of the central through hole. An input terminal is provided at the lower end of the scraping screw. The input terminal passes through the first shaft sleeve. The output shaft of the motor is inserted into the lower end of the central through hole and meshingly connected to the input terminal. The first shaft sleeve concentrically arranges the input terminal in the central through hole, enabling the input terminal to rotate relative to the bucket seat. It can be understood that the input terminal is provided with a spline hole. The output shaft of the motor is inserted into the spline hole to be meshingly connected with the input terminal, and there is no axial contact between the input terminal and the output shaft of the motor, avoiding the axial force generated by the scraping screw extruding the ice cubes from being transmitted to the output shaft of the motor and avoiding the loss of the output power of the motor.

[0010] According to the above solution, a limiting ring is provided in the central through hole. The lower end of the scraping screw abuts against the first shaft sleeve, and the lower end of the first shaft sleeve abuts against the limiting ring. The limiting ring protrudes on the inner wall of the central through hole, dividing the central through hole into upper and lower parts. Among them, the first shaft sleeve is arranged in the upper port of the central through hole, and the lower end of the first shaft sleeve is in contact connection with the limiting ring, so that the axial force generated when the scraping screw operates is applied to the bucket seat through the first shaft sleeve and then transmitted to the ice-making bucket through the bucket seat.

[0011] According to the above solution, a first sealing ring is provided in the lower port of the central through hole. The input terminal passes through the first sealing ring. The above input terminal is rotatably connected to the bucket seat, and there are gaps between the input terminal, the first shaft sleeve, and the central through hole. The first sealing ring is used to seal the central through hole to prevent the water in the ice-making bucket from leaking through the central through hole.

[0012] According to the above solution, the bucket seat and the ice-making bucket are fixedly connected through a snap structure or a threaded structure, and a second sealing ring is provided between the bucket seat and the ice-making bucket. Specifically, the bucket seat is inserted into the ice-making bucket. The snap structure or the threaded structure is a conventional existing technology, and it is only necessary to fixedly connect the bucket seat and the ice-making bucket. The second sealing ring is used to seal the lower port of the ice-making bucket to prevent internal water from leaking. Further, the snap structure and the threaded structure enable a detachable connection between the bucket seat and the ice-making bucket, which can facilitate the user to clean the internal water scale of the ice-making bucket, etc.

[0013] According to the above solution, an adapter seat is fixedly provided on the housing. A limiting block is provided on the upper end surface of the adapter seat, and a positioning groove is provided on the lower end surface of the bucket seat. When the bucket seat is placed on the adapter seat, the limiting block is paired and connected with the positioning groove, so that the housing is circumferentially cooperatively connected with the bucket seat. The vertical load received by the housing includes the component weights of the bucket seat and the ice-making bucket. There is also a transverse torque between the bucket seat and the housing, and this transverse torque is borne by the adapter seat. The adapter seat can be a structural extension of the housing or can be fixed on the housing as a separate component.

[0014] According to the above solution, a waterproof gasket is provided on the adapter seat, and the output shaft of the motor passes through the waterproof gasket. The adapter seat can be an integrally formed structure on the housing. The adapter seat can increase the structural strength of the housing. Of course, a hole is provided on the adapter seat for the output shaft of the motor to pass through, and the waterproof gasket is used to prevent water from entering the motor through the hole on the adapter seat.

[0015] According to the above solution, the present utility model further includes an ice extruder and an ice scraping cover. The ice extruder is covered on the upper port of the ice-making bucket. The ice extruder is provided with a shaft seat and a plurality of ice outlet holes; a connecting rod is provided at the upper end of the ice scraping screw, the connecting rod passes through the shaft seat and a second shaft sleeve is provided between the connecting rod and the shaft seat, and the upper end of the connecting rod is fixedly connected with the ice scraping cover. When the above-mentioned ice scraping screw rotates, it squeezes the ice in the ice-making bucket upward. The ice extruder controls the shape of the ice through a plurality of ice outlet holes. When the ice extruded from the ice outlet holes touches the ice scraping cover, it is broken, so as to obtain ice cubes of a specified size. The ice extruder abuts against the upper port of the ice-making bucket, and there is no rigid connection between the two, so that the ice extruder can be disassembled from the ice-making bucket, which is convenient for the user to clean and reassemble. It can be understood that the ice extruder is fixed on the ice outlet pipe of the ice maker, so that the ice extruder can be paired and connected with the upper end of the ice-making bucket.

[0016] For an installation structure of an ice-making component of the present utility model, the ice scraping screw squeezes the ice in the ice-making bucket, generating a downward axial force. This axial force is applied to the bucket seat and transmitted to the ice-making bucket. At the same time, the upward pushing of the ice will also generate an upward axial force on the ice-making bucket. The two forces cancel each other out, so that the ice scraping screw will not generate a working load on the motor and the housing, thereby simplifying the structural design of the ice maker and reducing the production cost.

The ice-making bucket 2, the bucket seat 3 and the ice scraping screw 21 form an ice-making component. By placing the bucket seat 3 on the housing 11 of the motor 1, the housing 11 of the motor 1 only bears the weight of this component. The bucket seat 3 and the housing 11 cannot rotate relative to each other, so that the motor 1 can drive the ice scraping screw 21 to rotate in the ice-making bucket 2 through the output shaft 12. The ice scraping screw 21 extrudes the ice cubes in the ice-making bucket 2, generating a downward axial force. This axial force is applied to the bucket seat 3 and transmitted to the ice-making bucket 2. At the same time, the upward pushing of the ice cubes will also generate an upward axial force on the ice-making bucket 2. The two forces cancel each other out and will not generate a working load on the motor 1 and the housing 11, thereby simplifying the structural design of the ice maker and reducing the production cost.
