AI Technical Summary
Ice makers must be installed near the sewer for drainage, which limits the installation location. The removable water collection box needs to be cleaned manually, is prone to deterioration and odor, and may overflow or cause short circuits due to water conductivity if drainage is not timely.
An auxiliary drainage system consisting of a water collection container, a DC pump, a level switch, and a controller is used. The DC pump is activated to drain the wastewater by detecting the level of the wastewater through the level switch. Automatic drainage is achieved by using the upper and lower drain pipes and the ventilation pipe to prevent water quality deterioration and overflow.
This allows the ice maker to be placed anywhere, with automatic drainage, preventing water quality deterioration and overflow, thus improving hygiene, safety, and equipment stability.

Abstract
Description
Technical Field
[0001] This utility model relates to the field of ice maker technology, specifically an auxiliary drainage device for ice makers. Background Technology
[0002] An ice maker is a device specifically designed to produce ice cubes, widely used in homes, commercial establishments such as bars, restaurants, and cafes, as well as in industrial settings. Depending on the application and specific needs, ice makers come in various types and specifications.
[0003] Chinese invention patent CN115388588A, published on November 25, 2022, discloses an ice maker, which includes a housing, a water receiving box, a first sensor, an ice-making system, a drain valve, and a controller. The housing has an assembly position for detachably connecting the water receiving box. The water receiving box is detachably connected to the assembly position. The first sensor senses whether the water receiving box is connected to the assembly position. The controller is electrically connected to the first sensor, the ice-making system, and the drain valve. The controller is configured to: determine whether the water receiving box is connected to the assembly position based on the detection result of the first sensor; if not, allow the ice-making system to perform ice-making operation and close the drain valve to prevent wastewater discharge through the drain valve. This ice maker can perform ice-making operation normally even when the water receiving box is removed, while also preventing wastewater overflow, providing a better user experience.
[0004] However, the aforementioned publicly available solutions have the following shortcomings: First, the machine must be placed near a sewer to ensure proper drainage during operation, which significantly restricts its installation location. Second, while the removable water collection box inside the casing allows for flexible installation, it requires regular manual cleaning and drainage. Furthermore, it lacks an automatic cleaning function, leading to water quality deterioration and unpleasant odors over time, raising concerns about the hygiene of the ice and posing a health risk if accidentally ingested. Additionally, if drainage is not timely, water may overflow into the casing, potentially causing a short circuit. Utility Model Content
[0005] The purpose of this invention is to address the problem that ice makers must be placed near sewers for proper drainage, which severely restricts their installation location. Secondly, while a removable water collection box inside the machine allows for more flexible installation, it requires regular manual cleaning and drainage and lacks an automatic cleaning function. Over time, the water quality deteriorates, producing an unpleasant odor, raising concerns about the hygiene of the ice and posing a health risk if accidentally ingested. Furthermore, if drainage is not timely, water may overflow into the machine, potentially causing a short circuit. This invention provides an auxiliary drainage device for ice makers.
[0006] To achieve the above objectives, the present invention adopts the following technical solution;
[0007] The present invention relates to an auxiliary drainage device for an ice maker, comprising a water collection container; a sealing plate is detachably and sealingly fixed to the upper opening of the water collection container; a sealing cover is detachably and fixedly fixed to the sealing plate; a controller is provided inside the sealing cover; a DC pump is electrically connected to the controller; the DC pump is fixedly fixed inside the water collection container; an intermediate pipe is connected and fixedly fixed to the DC pump; an upper drain pipe is connected and inserted into the intermediate pipe; a ventilation pipe is connected and fixedly fixed to the side of the water collection container; a liquid level switch is fixedly fixed to the sealing plate; and the liquid level switch is electrically connected to the controller.
[0008] Furthermore, a drain pipe is connected to the side of the water collection container.
[0009] Furthermore, a positioning base plate is fitted onto the lower end of the water collection container.
[0010] The auxiliary drainage device for an ice maker provided by this utility model has the following beneficial effects:
[0011] 1. This utility model features a ventilation pipe fixedly connected to the side of the water collection container, ensuring that the inflow and outflow of wastewater does not alter the atmospheric pressure inside the container, allowing the DC pump to operate normally. A level switch is fixedly connected to the sealed plate. The level switch is electrically connected to the controller, detecting the level of wastewater in the collection container. Once a certain amount of wastewater has accumulated, the level switch generates a signal to start the DC pump. The DC pump will then discharge all the wastewater. Therefore, after each discharge, the wastewater can be collected and poured into the sewer to complete the discharge process. This eliminates the need for external pipes to be inserted into the sewer, allowing the ice maker to be placed and used in any location.
[0012] 2. This utility model has a drain pipe connected to the side of the water collection container, which allows wastewater to enter the water collection container for storage. The lower end of the water collection container is fitted with a positioning base plate, which can limit the vibration displacement of the water collection container, making it less likely to cause displacement and resonance during use.
