Description

Technical Field

[0001] The invention relates to an ice making mechanism of a single ice granule ice making machine. Background Art

[0002] Patent CN202323296610.4 discloses an evaporator mechanism of an ice-making device, which includes a frame, an evaporation plate, and a water guide assembly. An ice-making grid is installed on the front surface of the evaporation plate. The water guide assembly is arranged at the upper frame position of the frame. Water is discharged through the water guide assembly. The water flows downward from the upper end of the ice-making grid and condenses into ice cubes in the grid of the ice-making grid. After subsequent heating, automatic defrosting can be achieved. However, the ice-making method has obvious disadvantages. For example, water flowing from top to bottom is easy to condense on the surface of the ice-making grid to form a whole piece of ice surface, that is, the ice particles are stuck together by the ice surface. When defrosting, the whole plate of ice may fall off. When the user takes ice, he needs to use an ice shovel to break the ice cubes to separate the ice particles into individual particles.

[0022] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0023] Please see attached Figure 1 , 2 6. The present invention provides an ice-making mechanism of a single-grain ice maker, which includes an ice-making mechanism and an ice-melting mechanism. The ice-making mechanism includes a bottom shell 1, an ice-making grid 2 and an evaporator 3. The bottom shell is provided with an installation cavity. The ice-making grid 2 is vertically arranged in the installation cavity and the ice outlet is arranged outward. The evaporator 3 is arranged at the back of the ice-making grid. The outer top wall of the installation cavity is provided with a water diversion structure to facilitate water to enter the ice-making grid. The bottom shell 1 is provided with a water outlet pipe 4 above the water diversion structure. The ice-making grid 2 is provided with an ice-isolating frame 5 for separating a plurality of ice grids. The ice-melting mechanism includes a driving component 6 and an ice-melting plate 7. The driving component is used to drive the ice-melting plate to move toward the ice-making grid 2. The surface of the ice-melting plate 7 facing the ice-making grid is provided with an ice-melting frame 8, and the ice-melting frame corresponds to the ice-isolating frame 5. A heating component 9 is provided on the ice-melting plate. After the ice cubes are made in the ice making grid, since this ice making method will result in a problem that a whole ice surface is formed on the surface of each ice particle, causing all the ice particles to be stuck together by the ice surface, the driving component is used to drive the ice melting plate to contact the ice making grid, and the ice melting frame is heated by the heating component, so that the ice melting frame cuts the ice surface into ice melting grooves corresponding to the shape of the ice partition frame, so that the ice particles become independent of each other again and no longer stick to each other. Therefore, when the ice making grid is subsequently de-iced, the de-iced ice particles are all in a single particle state and are not stuck to each other, so that users can take ice for use.

[0024] See attached Figure 3-5The ice melting mechanism also includes a detection component, which includes a bottom plate 10 and a plurality of detection units. The bottom plate is arranged behind the ice melting plate 7, and the bottom plate can move forward and backward relative to the ice melting plate. An elastic reset member 11 is arranged between the bottom plate 10 and the ice melting plate 7. The driving component 6 is connected to the bottom plate 10. Each grid of the ice melting frame is provided with a detection unit, and the detection unit is used to detect whether there is ice cube in the grid of the ice isolation frame 5. After the ice making grid performs the deicing process, the driving component drives the ice melting plate to contact the ice making grid again. After the ice melting plate contacts the ice making grid, the driving component drives the bottom plate to move toward the ice melting plate, so that the detection unit detects whether there is ice cube in the ice making grid. When ice cube is detected, it means that the ice making grid is not completely deiced. At this time, the driving component drives the bottom plate and the ice melting plate to retreat, and the ice making grid performs a deicing process again. When the deicing process is completed, the detection process of the above steps can be performed again by the driving component.

[0025] Specifically, the detection unit includes a first conductive sheet 12, a probe 13, a conductive spring 14 and a second conductive sheet 15. The first conductive sheet and the second conductive sheet are arranged front and back. One end of the probe 13 extends to the frame of the ice melting frame 8, and the other end of the probe is connected to the front end of the conductive spring 14. The front and rear ends of the conductive spring are respectively abutted against the first conductive sheet 12 and the second conductive sheet 15. When there are ice cubes in the ice making grid, the ice cubes will push the probe back. Since the probe is connected to the conductive spring, the conductive spring is disconnected from the first conductive sheet, thereby judging that there are still ice cubes in the ice making grid that have not been successfully thawed.

[0026] Among the multiple detection units, every two detection units are divided into a detection group and share the first conductive sheet 12, and adjacent detection groups share the second conductive sheet 15. With this structure, all the detection units can be connected in series. As long as the probe of one of the detection units is pushed open by ice cubes, the entire circuit will be disconnected, thereby judging that there are still ice cubes in the ice tray that have not been successfully thawed.

[0027] The ice melting plate 7 has a guide sleeve 16 connected to the probe 13, in which a guide channel for the probe to pass through is opened, and a hole for the probe 13 to pass through is opened on the frame of the ice melting frame 8. The guide sleeve can play a guiding role when the probe is extended and retracted to prevent the probe from being dislocated or shifted.

[0028] The ice melting plate 7 is provided with a first guide column 17 extending backwards, the first guide column passes through the bottom plate 10, and an anti-dropping portion is provided on the end passing through the bottom plate to prevent the bottom plate from getting loose. The elastic reset member 11 is a reset spring, and the reset spring is sleeved on the first guide column 17. With this structure, the bottom plate can be moved forward relative to the ice melting plate, and a probe can be used to detect whether there is residual ice in the ice making grid.

[0029] The ice-melting frame 8 is a metal ice-melting frame, and the heating component 9 is a heating film. The heating film is attached to the back of the ice-melting frame 8. The heating film has an avoidance opening at the position corresponding to the probe. The heating film has the advantages of fast heating efficiency, low power and high safety. It can quickly heat the ice-melting frame. The ice-melting frame is preferably made of metal material with good thermal conductivity.

[0030] The bottom shell 1 has a second guide column 18 extending toward the ice melting plate, and the ice melting plate has a sliding sleeve 19 slidably connected to the second guide column. With the cooperation of the second guide column and the sliding sleeve, it can play a guiding role when the ice melting plate moves toward the bottom shell, ensuring that the ice melting frame on the ice melting plate can accurately dock with the ice isolation frame on the ice making grid.

[0031] The driving assembly 6 in this embodiment can be a cylinder or an electric push rod.

[0032] The water diversion structure includes a plurality of water diversion concave surfaces 20, and the plurality of water diversion concave surfaces correspond one to one to the distribution of ice grids of the ice isolation frame 5. Water outlets are evenly distributed on the bottom of the water outlet pipe 4. Water in the water outlet pipe is evenly output to the water diversion structure, and the water is guided into the ice grid through the water diversion concave surfaces.

[0033] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in the field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
