Description

Technical Field

[0001] The invention relates to the technical field of ice cream machines, and in particular to a refrigeration device of an intelligent ice cream machine. Background Art

[0002] An ice cream machine is a device specifically used to make ice cream. Its working principle and functions can vary depending on the type and model. The refrigeration unit of an intelligent ice cream machine usually consists of the following key parts to ensure efficient refrigeration and convenient operation:

[0003] 1. Refrigeration system

[0004] Compressor: This is the core component of the refrigeration cycle and is responsible for compressing the refrigerant, raising its temperature and pressure, and then sending it to the condenser.

[0005] Condenser: In the condenser, the compressed refrigerant releases heat and turns into liquid. Common condensation methods include air cooling and water cooling.

[0006] Expansion valve: When the liquid refrigerant passes through the expansion valve, its pressure is reduced and it is transformed into a low-temperature and low-pressure gas, ready to enter the evaporator.

[0007] 2. Evaporator

[0008] The evaporator is the cooling part inside the ice cream machine where the low pressure gas absorbs heat and evaporates into gas, taking the heat with it, thus cooling the ice cream mixture.

[0009] The refrigeration device of this smart ice cream machine not only improves the refrigeration efficiency, but also enhances the user experience through intelligent control, making ice cream making easier and faster.

[0010] When the evaporator in the existing ice cream machine is in use, when the temperature of the evaporator is lower than the dew point, the moisture in the air will condense and freeze on its surface to form frost. The evaporator in the existing ice cream machine is not convenient for removing the frost when frost appears on its surface. Frost will hinder heat exchange, causing the evaporator to be unable to effectively absorb heat, thereby reducing refrigeration efficiency and affecting the speed and quality of ice cream production. Frost will cause the ice cream machine to run longer, resulting in increased energy consumption and increased operating costs.

[0011] In summary, the prior art lacks a technology for automatically removing frost from an evaporator in an ice cream machine. Summary of the invention

[0012] The purpose of the present invention is to solve the shortcomings of the background technology and to propose a refrigeration device for an intelligent ice cream machine.

[0013] To achieve the above objectives, the technical solution adopted by the present invention is: a refrigeration device of an intelligent ice cream machine, comprising an ice cream machine body, a rotating seat rotatably connected inside the ice cream machine body, an evaporator is installed on the rotating seat, a movable frame is slidably provided inside the ice cream machine body, a hot air hood is rotatably connected on the movable frame, an exhaust transmission mechanism is fixedly connected to the hot air hood, and a filter ring is rotatably connected to the inner wall of one side of the ice cream machine body.

A guide rod is slidingly provided at one end of the movable frame, and the other end of the guide rod is fixedly connected to the body of the ice cream machine. A spring is fixedly connected to the movable frame, and the other end of the spring is fixedly connected to the body of the ice cream machine.

[0018] Preferably, the air extraction transmission mechanism comprises a motor, the motor is connected and fixedly arranged with the hot gas hood, a driving wheel is connected and fixedly arranged with an output end of the motor, and a driven wheel is meshingly transmission-arranged with one side of the driving wheel.

[0019] Preferably, a rotating shaft is fixedly connected to the driven wheel, the rotating shaft is rotatably connected to the hot gas hood, and a fan blade is fixedly connected to one end of the rotating shaft located in the hot gas hood.

[0020] Preferably, a transmission wheel is fixedly connected to the outer end of the rotating shaft, and the transmission wheel is meshed with the annular rack A. The motor drives the driving wheel to rotate, so that the driving wheel drives the rotating shaft connected to the driven wheel to rotate, so that the rotating shaft drives the fan blades to rotate, so that the external air is filtered through the filter ring, and then injected into the hot air hood through the sliding sleeve and the rotating tube, and then the air is heated by the electric heating wire. At the same time, the rotating shaft meshes with the annular rack A through the transmission wheel, thereby driving the hot air hood to rotate.

[0021] Preferably, one end of the filter ring is located in the cleaning tank, one end of the filter ring is connected and fixedly provided with a universal joint, the other end of the universal joint is rotatably connected to the inner wall of the ice cream machine body, one end of the universal joint is connected and fixedly provided with an adjusting wheel, the adjusting wheel is meshing and transmitting with an arc-shaped rack, one side of the filter ring is connected and fixedly provided with an annular rack B, one side of the annular rack B is meshing and transmitting with a driving wheel, a movable rod is connected and fixedly provided on the driving wheel near the outer circle, a push-pull frame is slidably provided on the movable rod, both ends of the push-pull frame are rotatably connected with connecting rods, the other end of the connecting rod is rotatably connected with a brush rod, and the brush rod is slidably fitted with the inner wall of the cleaning tank.

According to the temperature of the evaporator and the thickness of the frost, it automatically starts and stops to realize intelligent defrosting, thereby extending the service life of the evaporator, improving the overall efficiency of the ice cream machine, ensuring the stable operation of the equipment, and avoiding performance degradation caused by frost;

[0024] By setting a filter ring, the air blown to the evaporator can be filtered. At the same time, the filter ring and the brush rod can be rotated to clean the filter ring with water melted from frost, which can effectively remove dust and impurities in the air, ensuring that the air entering the evaporator is cleaner, thereby reducing the possibility of frost.

[0025] By setting up the movable frame, under the action of the rotating seat and the spring, the hot air hood can be automatically driven close to the evaporator to remove frost. When the rotating seat is reset, the spring will drive the hot air hood to automatically reset, thereby realizing the automation of the device. BRIEF DESCRIPTION OF THE DRAWINGS

After being filtered by the filter ring 7, the external air is injected into the hot air hood 5 through the sliding sleeve 501 and the rotating tube 502, and then the air is heated by the electric heating wire 504, and the hot air is evenly sprayed on the evaporator 3 through the hot air hood 5 to melt the frost.

[0041] like Figure 7As shown, the air extraction transmission mechanism 6 includes a motor 601, which is fixedly connected to the hot gas hood 5, and a driving wheel 602 is fixedly connected to the output end of the motor 601, and a driven wheel 603 is meshed and transmission-equipped on one side of the driving wheel 602.
