Description

Technical Field

[0001] This utility model relates to the field of drinking water equipment technology, and in particular to a countertop water purifier that prevents ice from getting stuck. Background Technology

[0002] Countertop ice makers and water purifiers are household appliances that integrate filtration, purification, heating, cooling, and ice making, and are very popular among users. Their ice-making mechanism typically uses a compressor for refrigeration, and the produced ice is stored in an ice storage cylinder, then dispensed via a rotating ice-making mechanism.

[0003] However, variations in compressor power, refrigerant content, water temperature, and ambient temperature can lead to uneven ice block sizes. During the ice dispensing process, excessively large ice blocks or ice buildup can easily get stuck between the rotating spring and the ice storage cylinder, causing dispensing failure. Current technology typically attempts to address this issue by using timed control of the rotating motor's forward and reverse rotation. However, this method cannot accurately determine if ice jamming has actually occurred: reversing the rotation when there is no jamming will reduce dispensing efficiency; conversely, failing to reverse the rotation in time when ice jamming has occurred may cause the motor to stall and burn out or damage the mechanism. Furthermore, uneven ice dispensing and excessively long waiting times severely impact the user experience.

[0004] Therefore, a countertop water purifier that can automatically and accurately detect and handle ice-stuck issues urgently needs to be researched. Utility Model Content

[0005] The purpose of this invention is to provide a countertop water purifier that prevents ice jamming. When ice jamming is detected, the motor is automatically reversed to ensure smooth ice dispensing. It is simple and reliable in structure.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: This utility model provides a countertop water purifier that prevents ice from getting stuck, including a housing. The housing is provided with an ice-making mechanism, an ice storage compartment, and an ice-dispensing mechanism. The ice-dispensing mechanism includes an ice-dispensing spring for dispensing ice and an ice-dispensing motor for driving the ice-dispensing spring to rotate. It also includes a control unit and an ice-sticking detection device. The ice-sticking detection device is used to detect the rotation state of the ice-dispensing spring. The control unit connects the ice-sticking detection device and the ice-dispensing motor, and is used to control the ice-dispensing motor to rotate forward to perform the ice dispensing operation. When the ice-sticking detection device detects ice sticking, it controls the ice-dispensing motor to rotate in reverse. Furthermore, the ice-catching detection device includes a sensing element and a sensing element that rotates synchronously with the ice-rotating spring.

[0007] Furthermore, the sensing element is a magnet, which is fixedly mounted on the ice-rotating spring; the sensing element is a proximity switch, which is connected to the outside of the ice storage compartment and is set to correspond to the rotation trajectory of the magnet.

[0008] Furthermore, the control unit is signal-connected to the proximity switch and the ice spinning motor. When the sensing signal interruption time of the proximity switch exceeds a preset time threshold, the control unit controls the ice spinning motor to reverse.

[0009] Furthermore, the control unit drives the ice-spinning motor to rotate at a fixed cycle, and the preset time threshold is greater than the fixed cycle.

[0010] Furthermore, the ice-rotating motor is an AC motor capable of forward and reverse rotation.

[0011] Furthermore, the ice-making mechanism is a compressor-cooled ice maker.

[0012] Furthermore, the water purifier also includes a water filtration module and a heating module disposed within the housing.

[0013] In summary, this utility model has the following beneficial effects: This utility model of a countertop water purifier that prevents ice jamming uses a combination of sensing and sensing elements to monitor the operation of the ice-spinning mechanism in real time and accurately. When ice jamming is detected, the motor is automatically reversed, effectively preventing motor blockage and damage, ensuring smooth and reliable ice dispensing, improving the product's ease of use and user satisfaction, and featuring a simple, reliable, and low-cost structure.

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] This embodiment discloses a countertop water purifier that prevents ice buildup, referring to... Figures 1-4 It includes a housing 1, which integrates a water purification filter module 7, a heating module 8, a compressor-type ice maker 9, an ice storage bin 2, and an ice swirl and ice dispensing mechanism 3.

[0021] The ice-discharging mechanism 3 includes a rotatable ice-rotating spring 31 and an ice-rotating motor 32 for driving its rotation. In this embodiment, the ice-rotating motor 32 is a reversible AC motor. When it is working normally (rotating forward), it drives the ice-rotating spring 31 to rotate at a constant speed with a fixed cycle of about 4 seconds per revolution, thus pushing out the ice blocks in the ice storage chamber 2.

[0022] The ice-catching detection device includes a sensing element and a sensing element that rotates synchronously with the ice-rotating spring 31. The sensing element is a magnet 5, which is fixedly installed on the rotating shaft of the ice-rotating spring 31 and rotates together with the ice-rotating spring 31. The sensing element is a proximity switch 6, which is preferably a Hall sensor in this embodiment. The proximity switch 6 is connected to the outside of the ice storage chamber 2 and is set to correspond to the rotation trajectory of the magnet 5.

[0023] The control unit 4 is signal-connected to the proximity switch 6 and the ice-spinning motor 32. When the interruption time of the sensing signal of the proximity switch 6 exceeds a preset time threshold, the control unit 4 controls the ice-spinning motor 32 to reverse. The control unit 4, proximity switch 6, and ice-spinning motor 32 are electrically connected through wires and connectors. The control unit 4 drives the ice-spinning motor 32 to rotate at a fixed period, and the preset time threshold (4.5 seconds) is greater than the fixed period (4 seconds).

[0024] When ice is removed, the ice-rotating motor 32 drives the ice-rotating spring 31 to rotate at a constant speed with a fixed cycle (4 seconds). The proximity switch 6 should be triggered once by the magnet 5 in each rotation cycle, generating a sensing signal. The control unit receives the signal from the proximity switch 6. If the control unit 4 does not receive a sensing signal within the preset monitoring time (longer than 4 seconds), it can determine that the ice-rotating spring 31 has stopped rotating due to ice jamming. Then, the control unit 4 issues a command to reverse the ice-rotating motor 32 for a period of time. This achieves accurate and real-time judgment of the ice jamming state, avoiding invalid reversals or delayed response.

[0025] The working principle of this invention is as follows: Under normal ice-discharging conditions, for every rotation of the ice-rotating spring 31 (approximately 4 seconds), the magnet 5 passes the proximity switch 6 once, triggering the proximity switch 6 to generate a pulse signal, which is then sent to the control unit 4. The control unit 4 contains a timer and a preset time threshold slightly longer than the normal cycle (4.5 seconds). When ice jamming occurs, the ice-rotating motor 32 stops driving the ice-rotating spring 31 to rotate, and the magnet 5 can no longer pass the proximity switch 6. If the control unit 4 fails to receive the next pulse signal from the proximity switch 6 within the preset time window, it is considered that ice jamming has occurred. The control unit 4 then sends a reverse command to the ice-rotating motor 32, causing the ice-rotating motor 32 to drive the ice-rotating spring 31 to rotate in the opposite direction by a certain angle or for a period of time, loosening the jammed ice. Afterward, the control unit 4 controls the ice-rotating motor 32 to resume forward rotation, continuing the normal ice-discharging process.

[0026] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
