Description

Technical Field

[0001] This utility model relates to a refrigeration device, and more particularly to a multifunctional refrigeration device. Background Technology

[0002] Most existing ice-making equipment is designed for a single function. It either only makes ice cubes, relying on an evaporator to continuously freeze the ice layer at low temperatures and lacks a specialized stirring structure, or it only makes slushies, relying on high-speed stirring and low temperatures, but making it difficult to stably control the ice layer thickness. This fails to meet the flexible needs of users in homes, beverage shops, and other settings who require the same equipment to switch between slushie making, ice cube making, preservation, and sterilization. Consequently, users need to purchase multiple units, increasing operating costs and space requirements. Utility Model Content

[0029] Please see Figure 1-3 This utility model protects a multifunctional refrigeration device used for making shaved ice or ice cubes, comprising:

[0030] The system comprises a refrigeration system, a stirring system, a control system, and auxiliary systems. The refrigeration system includes a compressor 5, a condenser, an ice-making evaporator 3 for condensing ice, and an ice-making cylinder 1, all connected via refrigeration piping. The ice-making cylinder 1 and the ice-making evaporator 3 together form an ice-making chamber 11. The ice-making evaporator 3 includes at least two ice-making surfaces on different planes. The stirring system 2 includes a stirring blade and a drive assembly 4, which are connected by a drive mechanism. The stirring blade is detachably mounted on the ice-making evaporator 3, and the drive assembly 4 drives the stirring blade to rotate around the central axis of the ice-making evaporator 3 to scrape and stir the ice layer on the ice-making surface. The control system includes a user input module for receiving user operation commands and an execution control module. The user input module and the execution control module are electrically connected to the user input module, the refrigeration system, and the stirring system 2, respectively. The control system controls the start and stop of the refrigeration system according to the setting commands from the user input module and the operating status of the stirring system 2. An auxiliary system includes an accessory disposed within the ice-making cavity 11. The accessory is at least one of an ice-making box 13, a food storage box 14, and a dispersing liquid dispensing mechanism for uniformly dispersing ice-making ingredients onto the ice-making surface. The dispersing liquid dispensing mechanism is disposed above at least one ice-making surface.

[0031] This design allows a single refrigeration unit to perform multiple functions, including ice making, shaved ice making, and food preservation. When making ice cubes, the stirring blades can be detached, and the ice-making container can be placed directly against at least one ice-making surface for rapid cooling. Preferred ice-making containers include, but are not limited to, curved shapes to fit the circular ice-making cavity shape of most ice-making devices. The ice-making container has multiple ice compartments. Food preservation containers can be used to hold small cakes, small fruits, etc. These containers are preferably positioned above the ice-making cavity to avoid direct contact with the stirring system and to prevent obstruction of its operation.

[0032] Furthermore, the execution control module includes a precooling control module, which includes a precooling start / stop module, a precooling time module, and a target operating status module after precooling is completed.

[0033] Furthermore, the dispersing liquid addition mechanism is a permeation plate 12, which is detachably disposed in the ice-making chamber 11; the permeation plate 12 is provided with a plurality of permeation holes 121.

[0034] Furthermore, the spacing between adjacent permeation holes 121 is 1mm-40mm, and the diameter of each permeation hole 121 is 0.1mm-10mm. If only a dispersion function is desired, the diameter of the permeation hole can be set slightly larger to allow the liquid ice-making raw material to disperse quickly; if both dispersion and permeation are desired, the diameter of the permeation hole can be set slightly smaller to allow the liquid ice-making raw material to disperse and drip slowly and continuously onto the ice-making surface for a period of time, achieving continuous, uniform, and rapid condensation of the ice layer and improving ice-making speed and efficiency.

[0035] Furthermore, the multi-functional refrigeration equipment includes a discharging mechanism 17, which is snap-fitted to the ice-making cylinder 1. The discharging mechanism communicates with the ice-making chamber to control the discharging. The discharging mechanism includes, but is not limited to, a handle and a discharging port. Preferably, the discharging mechanism 17 is snap-fitted to the outer wall of the inner cylinder of the ice-making cylinder and communicates with the ice-making chamber to control the discharging. The outer cylinder has a discharging slot corresponding to the discharging mechanism. Preferably, a water collection seat 6 for collecting dripping waste such as ice slush can also be provided below the discharging port. The user input module includes a pre-cooling control switch that issues corresponding user operation commands. A separate control switch can be used to control the pre-cooling function, or it can be integrated into other function switches.

[0036] Furthermore, the ice-making cylinder 1 includes a transparent inner cylinder and an outer cylinder, with a gap forming between them; this gap provides insulation, and the visible ice-making cylinder allows for real-time observation of the ice-making process; a germicidal lamp strip 16 is installed within the gap to direct light into the ice-making cavity 11. Preferably, a mounting portion is provided on the bottom outer wall of the inner cylinder, and the germicidal lamp strip is fixed to the mounting portion. The germicidal lamp strip emits ultraviolet or other germicidal light to sterilize the food inside the ice-making cavity.

[0037] Furthermore, the ice-making surface includes a first ice-making surface 31 and a second ice-making surface 32 that are perpendicular to each other; the stirring blade includes a first scraper 21 and a second scraper 22, with the first scraper 21 fitted to the first ice-making surface 31 and the second scraper 22 fitted to the second ice-making surface 32. This increases the ice-making surface area, speeds up ice-making, and improves ice-making efficiency. It also enables multi-plane and multi-angle ice making and stirring, preventing ice layers from accumulating in the ice-making cylinder and on the evaporator for too long, resulting in a dense and uniform ice slush.

[0038] Furthermore, the ice-making evaporator 3 has a drive channel inside, and the drive assembly 4 extends out of the drive channel and is connected to the stirring blade drive.

[0039] Furthermore, the stirring blades, from top to bottom, include a top scraping zone, a middle scraping zone, and a bottom scraping zone, with the bottom scraping zone ending in a hook shape; the stirring blades also include inclined reinforcing ribs. Multiple zones scrape away the ice layer from the stirring evaporator and ice-making cylinder, further improving the uniformity of stirring.

[0040] The precooling control method for a multi-functional ice-making device may include the following steps:

[0041] Pre-cooling instruction reception: The pre-cooling control module receives user operation instructions sent by the user input module, including the pre-cooling time T and the target state S after pre-cooling is completed;

[0042] Status detection: Detects whether the real-time motion status of the stirring system 2 is stationary or in motion;

[0043] Pre-cooling execution: If the real-time motion state of the stirring system 2 is stationary, the pre-cooling control module starts the refrigeration system to lower the surface temperature of the ice making to -5℃~-35℃; if the real-time motion state of the stirring system 2 is in motion, the drive component 4 is stopped first, and the refrigeration system is started after the stirring system 2 comes to a standstill.

[0044] State switching: When the precooling time reaches the set value T, the refrigeration system stops operating, and the precooling control module performs operations according to the set target state S:

[0045] If S is in standby mode: the cooling system is turned off and low-power operation is maintained;

[0046] If S is set to power off: Disconnect the main power supply to the equipment;

[0047] If S is for heat preservation: continue executing the previous instruction and display the heat preservation duration;

[0048] If S is ice slush: directly start the corresponding ice-making mode setting and run the stirring system 2 according to the ice-making parameters set by the user input module.

[0049] If S is an ice block: directly start the corresponding ice-making mode and set the stirring system 2 not to run, and run according to the ice-making parameters set by the user input module.

[0050] This allows for pre-cooling, enabling immediate slush making or food preservation when needed. After the pre-cooling function completes, the system can directly proceed to the target state for the aforementioned functions.

[0051] Furthermore, during or after the pre-cooling process, liquid ice-making raw materials are injected from the feed inlet of the refrigeration equipment. The liquid ice-making raw materials are evenly dispersed onto the ice-making surface by the dispersing and dispensing mechanism, and immediately condense into an ice layer.

[0052] The method for controlling the ice-making process of a multi-functional ice-making device may include the following steps:

[0053] Ice Smoothie Command Reception: The execution control module receives user operation commands sent by the user input module to set the operating parameters of the ice smoothie mode, including the stirring blade speed R and ice-making time N;

[0054] Ice making process: The refrigeration system and drive component 4 are started simultaneously, and the stirring blades start to rotate at speed R, so that the surface temperature of the ice-making process drops to -1℃ to -25℃.

[0055] Ice slush stop: When the running time reaches N or the torque sensor of the stirring system 2 detects that the stirring resistance has reached the preset value, the refrigeration system and drive component 4 are stopped, and the stirring blades stop rotating.

[0056] This method can make smoothies and automatically stop making them when the smoothie is ready.

[0057] The advantages of this utility model are:

[0058] Multifunctional: It can make smoothies / ice cubes, preserve freshness, and sterilize. The ice evaporator has multiple flat ice-making surfaces and corresponding stirring scrapers to adapt to different ice-making needs. It is equipped with a sterilization light strip to sterilize food in the ice-making chamber, eliminating the need for multiple devices.

[0059] Flexible operation: The user input module supports setting pre-cooling and ice-making parameters and selecting the status after completion. It features physical keys and a display unit, making it intuitive and convenient.

[0060] Highly efficient ice making: The permeation disc feeds the material evenly, and the stirring blades are detachable and can scrape ice in multiple areas, ensuring a uniform ice layer and fine ice slush.

[0061] Intelligent energy saving: The execution control module links the refrigeration and stirring system. During pre-cooling, stirring is stopped first and then restarted. After completion, the state is switched as needed to reduce energy consumption.

[0062] The above embodiments are preferred embodiments of the present utility model, but the embodiments of the present utility model are not limited thereto. Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model are equivalent substitutions and are included within the protection scope of the present utility model.
