Detailed Implementation

[0018] See Figure 8 The present invention provides an ice quantity detection component, including an ice collection drawer 2; a guide sleeve 72 is provided above the ice collection drawer 2; a sliding rod 7 capable of reciprocating in the vertical direction is sleeved inside the guide sleeve 72; the lower end of the sliding rod 7 can extend into the ice collection drawer 2; Combination Figure 9 The sliding rod 7 is provided with a trigger block 73; it also includes a sensor 8, configured to detect a corresponding feedback signal when the trigger block 73 approaches; and a controller, configured to receive the feedback signal from the sensor 8 and issue a corresponding control signal; specifically: When the trigger block 73 passes over or under the sensor 8, the sensor 8 is turned on once and then immediately turned off, sending an instantaneous feedback signal to the controller, while the controller does not send a signal. When the trigger block 73 is in the position of the sensor 8, the sensor 8 is continuously turned on and sends a continuous feedback signal to the controller, and the controller sends a stop signal. In one embodiment, the sensor 8 is a magnetic switch and the trigger block 73 is a magnet.

[0019] Furthermore, the lower end of the sliding rod 7 is fixedly connected to the detection plate 71; Furthermore, a stop block 75 is provided on the outer wall of the sliding rod 7. The stop block 75 can abut against the top of the guide sleeve 72 to limit the lowest position of the sliding rod 7 when it falls.

[0020] See Figure 10 and Figure 11 The detection method of the present invention is as follows: Initially, the sliding rod 7 is at its highest position in the vertical direction; During testing, release the sliding rod 7 to allow it to fall freely until it reaches the lowest point or the testing plate 71 contacts the ice block and stops falling. If, during the descent of the sliding rod 7, the trigger block 73 passes through the sensor 8 from above, the sensor 8 is activated once and then immediately deactivated; this indicates that the amount of ice in the ice collection drawer 2 has not reached the limit value, the controller does not send a signal, and the ice collection drawer 2 can continue to accumulate ice.

[0021] If the sliding rod 7 stops at the position of the sensor 8 during the descent, and the sensor 8 remains on, it indicates that the ice content in the ice drawer 2 has reached the limit. The controller will then issue a stop signal to remind the user to remove the ice in time.

[0022] After the test is completed, the sliding rod 7 is pulled up to reset to the initial state; during the reset process, the trigger block 73 passes through the sensor 8 from below, the sensor 8 is turned on once and then turned off, and the controller does not send a signal.

[0023] Preferably, the two ends of the detection plate 71 form upturned portions 711 to prevent it from being stuck by ice.

[0024] The ice quantity detection component of this invention uses a sliding rod 7 and a trigger block 73 to cause a sensor 8 to generate a feedback signal, determining whether the amount of ice in the ice collection drawer 2 has reached a predetermined value. This achieves automatic ice quantity detection and provides a prerequisite technology for automatic ice making.

[0025] As one embodiment, the ice quantity detection component of the present invention further includes a lifting lever gear 34, which is provided with at least one set of lever teeth 341; the outer wall of the sliding rod 7 is provided with driving teeth 74 that can contact and cooperate with the lever teeth 341. In the initial state, the lifting gear 34 stops rotating, and its driving teeth 74 abut against the lever teeth 341 to stop the sliding rod 7 at the highest position; During the testing process, the lifting gear 34 rotates, the drive tooth 74 disengages from the lever tooth 341, and the sliding rod 7 falls freely. During the reset process, the lifting gear 34 continues to rotate, and the driving gear 74 contacts the lever gear 341 again from below, causing the sliding rod 7 to slide upward and finally stop at the highest position.

[0026] See Figure 1 The present invention also provides an ice maker having the ice quantity detection component, including a box body 1, wherein the bottom of the box body 1 is provided with the ice collection drawer 2; See Figure 5 and Figure 6The box body 1 has a rotating frame 5 inside; the rotating frame 5 has two metal ice boxes 4 arranged back to back facing each other; the ice boxes 4 have multiple ice trays 41 recessed on them. See Figure 2 The box body 1 has an air inlet 12 at one end and an air outlet 13 on each side of the box body 1; the rotating frame 5 has a clearance hole on the side facing the air inlet 12; and an air duct connecting the air inlet 12 and the air outlet 13 is formed between the two ice boxes 4. See Figure 7 The ice box 4 has a heating wire 42 on its back side; the heating wire 42 is attached to the outer side wall of each ice tray 41 in sequence. The ice-making principle of this invention: One of the two ice cube trays 4 has its opening facing upwards, and the other has its opening facing downwards. Water is added to the ice cube tray 4 with its opening facing upwards. Cold air enters from the air inlet 12, flows through the air duct between the two ice cube trays 4, and finally flows out from the air outlet 13. Utilizing the heat conduction of the metal ice cube tray 4, it condenses into ice cubes.

[0027] The rotating frame 5 rotates 180°, switching the orientation of the two ice cube trays 4. The heating wire 42 of the ice cube tray 4 with its opening facing downward is energized and heats up. Through the heat conduction of the metal ice cube tray 4, a film of melted water is formed between the ice cube and the inner wall of the ice tray 41. The ice cube falls into the ice collection drawer 2 below under the action of gravity.

[0028] The energizing time of the heating wire 42 in this invention can be determined based on the specifications of the heating wire 42 and through experiments, to establish a minimum heating time or range. To ensure that the ice cube can be completely removed, the minimum heating time can be appropriately extended.

[0029] As one embodiment, the distance between the back sides of the two ice boxes 4 is no greater than the diameter of the air inlet 12. After the cold air enters, it can fully contact and exchange heat with the outer wall of the ice tray 41, thereby improving the ice-making efficiency.

[0030] This invention uses two ice-making containers 4 facing away from each other, allowing the cooling airflow to pass through the back sides of the two containers 4. Simultaneously, a heating wire 42 detaches the ice cubes from the ice-making containers 4 and allows them to fall into the ice collection drawer 2 for storage. Both the ice-making and storage processes avoid direct contact between the airflow and the ice cubes, eliminating hygiene concerns. The metal ice-making containers 4 have good thermal conductivity, improving ice-making efficiency.

[0031] Optionally, a water tank is connected between two adjacent ice trays 41 on the ice box 4.

[0032] Combination Figure 2As one embodiment, the top of the box body 1 is provided with a lid 15; this can cover the ice-making box 4 with its opening facing upwards, preventing foreign objects from falling in and reducing airflow on the surface of the ice trays 41.

[0034] Furthermore, each set of guide rail beams 54 consists of two beams, and each guide rail beam 54 has a groove 55; both sides of the ice box 4 have a sprue structure, and the two sprue structures slide into the groove 55 on the corresponding side; thus realizing the detachable connection between the ice box 4 and the rotating frame 5.

During this process, the ice quantity detection component completes a detection and reset process. That is, every time ice is poured, the amount of ice in the ice collection drawer 2 is detected. If the amount of ice in the ice collection drawer 2 reaches a limit value, a stop signal is issued to stop ice making or stop the switching of the ice-making boxes 4.

[0037] See Figure 2As one embodiment, the ice collection drawer 2 has rail grooves on both sides of the top, and the lower part of the box body 1 has a slide rail 17 that slides in cooperation with the rail grooves; this facilitates the pulling out of the ice collection drawer 2.

[0038] See Figure 3 Furthermore, both the rear cover 11 and the ice collection drawer 2 are equipped with self-locking magnets 18; after the ice collection drawer 2 is closed, the magnetic attraction between the two self-locking magnets 18 is used to prevent the ice collection drawer 2 from opening on its own.
