Description

Technical Field

[0001] This utility model relates to the field of beverage rapid cooling technology, specifically to a variable frequency beverage rapid cooling device. Background Technology

[0002] Currently, there are various types of beverage coolers and slush machines on the market, used for cooling beverages at home to lower their temperature or to solidify them. The compressors used in the refrigeration circulation systems of these beverage coolers and slush machines are mainly fixed-frequency compressors. The main problems are: small-displacement fixed-frequency compressors have low cooling output and slow cooling speed, resulting in long waiting times and a poor user experience; while large-displacement fixed-frequency compressors meet the cooling output requirements, their larger size leads to a larger overall machine size and limited installation space; moreover, once the beverage has reached its solidified state or temperature, if the user does not enjoy it in time, the fixed-frequency compressor will either frequently start and stop according to the set program, wasting energy, or it will stop according to the set program, causing changes in the food's form or temperature, affecting its taste. Utility Model Content

[0003] The purpose of this invention is to provide a beverage rapid cooling device. The refrigeration system uses a variable frequency compressor, whose speed is adjusted by a variable frequency control circuit. It outputs a large cooling capacity at high speed and a small cooling capacity at low speed, achieving rapid cooling at high speed and maintaining the shape and temperature of the food after it has been formed at low speed, thus ensuring the food's taste. Comparative tests show that, with comparable refrigeration system configurations, the variable frequency compressor can increase the cooling speed by more than 20% compared to a fixed frequency compressor of similar size, significantly reducing user waiting time.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A variable frequency beverage rapid cooling device includes a housing, a filling cylinder, a chassis, and a refrigeration system. The housing is mounted on the chassis, and the filling cylinder is mounted on the housing. The refrigeration system includes a coolant and an evaporator, a condenser, and a variable frequency compressor connected to each other. The evaporator is located inside the filling cylinder, and the condenser and the variable frequency compressor are located inside the housing. The device is characterized by further including a variable frequency control circuit. The variable frequency control circuit includes a variable frequency control board assembly, an operation panel assembly, and a temperature sensor. The temperature sensor is located inside the evaporator and is signal-connected to the operation panel assembly. The operation panel assembly is signal-connected to the variable frequency control board assembly, and the variable frequency control board assembly is signal-connected to the variable frequency compressor.

[0005] Preferably, the temperature sensor is located at the front end of the evaporator near the outlet of the charging cylinder.

[0006] Preferably, the operation panel assembly is connected to the frequency converter control board assembly via a data cable.

[0007] Preferably, a drying filter is provided between the evaporator and the condenser.

[0008] Preferably, capillary tubes are provided between the evaporator and the dryer filter, and between the evaporator and the variable frequency compressor.

[0009] The variable frequency beverage rapid cooling device of this utility model has the following advantages compared with the prior art: This variable frequency beverage rapid cooling device achieves precise and intelligent control of the refrigeration system by introducing a variable frequency control circuit. The circuit adjusts the speed of the variable frequency compressor, outputting a large cooling capacity at high speed and a small cooling capacity at low speed. This allows for rapid cooling at high speeds and maintains the shape and temperature of the food after it has been formed, thus ensuring its taste. A temperature sensor monitors temperature changes within the evaporator in real time and transmits the signal to the control panel assembly. Users can easily set and adjust cooling parameters. The control panel assembly further interacts with the variable frequency control board assembly, which ultimately dynamically adjusts the operating status of the variable frequency compressor. This closed-loop control system significantly improves the response speed and accuracy of temperature regulation, effectively enhancing the automation level of the equipment and the convenience of user operation.

[0010] Placing a temperature sensor at a critical location near the outlet of the charging cylinder at the front end of the evaporator allows for accurate real-time temperature sensing during beverage dispensing, ensuring direct control over the final cooling effect. A dryer filter installed between the evaporator and condenser effectively adsorbs moisture and impurities from the system, ensuring refrigerant purity. Simultaneously, capillary tubes are installed between the evaporator and the dryer filter, and between the evaporator and the variable frequency compressor, to stabilize throttling and pressure reduction, optimizing refrigerant circulation efficiency within the system and collectively improving the reliability and lifespan of the refrigeration system.

[0011] By employing a variable frequency compressor and combining it with an intelligent control strategy, this device can steplessly adjust the compressor's power according to actual cooling needs, avoiding the energy consumption problems caused by frequent start-stop cycles of traditional fixed frequency compressors, and significantly reducing operating noise and energy consumption. The entire system has a reasonable structural design, with all components working in concert, ultimately achieving high efficiency and low power consumption for rapid beverage cooling, offering the dual benefits of energy saving, environmental protection, and a superior user experience.

Detailed Implementation

[0013] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: outer casing 1, charging cylinder 2, chassis 3, evaporator 4, condenser 5, variable frequency compressor 6, variable frequency control board assembly 7, operation panel assembly 8, temperature sensor 9, dryer filter 10, and capillary tube 11.

[0014] As attached Figure 1-3 As shown in the figure, this embodiment illustrates a specific implementation of a variable frequency beverage rapid cooling device. The device consists of a housing 1, a filling cylinder 2, a chassis 3, and a refrigeration system. The housing 1 is fixedly mounted above the chassis 3, serving to support and enclose the internal components. The filling cylinder 2, located on the upper part of the housing 1, is used to hold the beverage to be cooled. The refrigeration system is the core component, containing coolant and an evaporator 4, a condenser 5, and a variable frequency compressor 6 connected by pipes. The evaporator 4 is located inside the filling cylinder 2, directly exchanging heat with the beverage; while the condenser 5 and the variable frequency compressor 6 are installed in a reserved space inside the housing 1, resulting in a compact structure that facilitates overall heat dissipation and maintenance.

[0015] Based on this, the device also integrates a frequency conversion control circuit. This circuit system mainly consists of three parts: a frequency conversion control board assembly 7, an operation panel assembly 8, and a temperature sensor 9. The temperature sensor 9 is installed inside the evaporator 4, with its sensing end preferably located at the front of the evaporator 4 and near the outlet of the filling cylinder 2, thus accurately sensing the real-time temperature of the beverage about to flow out. This sensor establishes a signal connection with the operation panel assembly 8, uploading temperature data in real time.

[0016] Meanwhile, the control panel assembly 8 is connected to the inverter control board assembly 7 via an internal data cable. The user can set the desired temperature or cooling mode on the control panel assembly 8, and the command is transmitted to the inverter control board assembly 7. The inverter control board assembly 7 receives signals from the control panel and the temperature sensor 9, processes them, and sends control commands to the inverter compressor 6, thereby dynamically adjusting its operating frequency and cooling power.

[0017] Furthermore, in the refrigeration cycle piping design, a dryer filter 10 is connected in series between the evaporator 4 and the condenser 5 to adsorb residual moisture and impurities in the system, ensuring the purity and smooth circulation of the refrigerant. Moreover, capillary tubes 11 are installed as throttling elements on the piping between the evaporator 4 and the dryer filter 10, and between the evaporator 4 and the variable frequency compressor 6, playing a crucial role in reducing pressure and regulating refrigerant flow, further ensuring the stability and energy efficiency of the system operation.

[0018] When powered on, the user can select the corresponding function button on the control panel component 8 according to the type of beverage. After pressing the button, the circuit is connected, and the electrical signal is transmitted to the chip inside the control panel component 8. After receiving the signal, the chip issues a corresponding instruction, transmitting the preset control program to the frequency converter control board component 7 via the data line. The frequency converter control board component 7 then drives the frequency converter compressor 6 to start running at the preset speed.

[0019] During operation, the control panel assembly 8 continuously receives temperature change rate signals from the temperature sensor 9 and sends commands to the frequency converter control board assembly 7 accordingly to dynamically adjust the speed of the frequency converter compressor 6 or maintain the current speed for stable operation.

[0020] Once the beverage has cooled and solidified or reached the set temperature, the control panel assembly 8 sends a command to the frequency converter control board assembly 7 based on the signal transmitted from the temperature sensor 9, reducing the speed of the frequency converter compressor 6. The compressor will then enter a low-speed continuous operation mode according to a preset program to maintain the beverage's cooling state and temperature stability, preventing temperature fluctuations from affecting the food's taste. The frequency converter compressor 6 will only completely stop operating once the control panel assembly 8 determines from the temperature information that the food in the filling cylinder 2 has been completely consumed.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the structure of this utility model, and these should also be considered within the scope of protection of this utility model.

The scope of protection claimed in this application shall be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
