Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, and in particular to an ice cream machine. Background Technology

[0002] In existing ice cream making equipment, the motor, as the core drive component, is responsible for the main power output, and it generates a lot of heat during prolonged operation. If the heat cannot be dissipated in time, the motor temperature will rise, affecting the equipment performance and even shortening the motor's lifespan.

[0003] However, current ice cream making equipment typically mounts the motor directly inside the equipment housing, failing to create a proper heat dissipation or heat conduction structure. This causes the heat generated by the motor to accumulate in the enclosed space, making it difficult to dissipate effectively. Especially during continuous operation or in high-temperature environments, the motor is prone to overheating and triggering protective shutdown, affecting operational efficiency.

[0023] In current technology, ice cream making equipment typically mounts the motor directly inside the equipment housing, failing to create a proper heat dissipation or heat conduction structure. This causes the heat generated by the motor to accumulate in the enclosed space, making it difficult to dissipate effectively. Especially during continuous operation or in high-temperature environments, the motor is prone to overheating and triggering protective shutdown, affecting operational efficiency.

[0024] This utility model proposes an ice cream machine.

[0025] Please see Figures 1 to 5In one embodiment of this utility model, the ice cream machine includes: a housing 100, a first drive motor 200, a cup holder 400, and a cooling fan 500; wherein, the housing 100 is provided with an installation space and a heat dissipation hole 110 communicating with the installation space; the first drive motor 200 is located in the installation space, drives a blade 300 connected to it, and drives the blade 300 to rotate; the cup holder 400 is located in the installation space and is used to install a cup body 410, the cup holder 400 moves relative to the blade 300, and the rotation of the blade 300 grinds the ice cubes in the cup body 410 assembly; the cooling fan 500 is located in the installation space, the rotation of the cooling fan 500 forms a cooling airflow flowing through the first drive motor 200 to dissipate heat from the first drive motor 200, and the cooling airflow is discharged through the heat dissipation hole 110.

[0026] It should be noted that the reference Figure 5 As shown, in the ice cream machine proposed in this embodiment, the cup body 410 is pre-filled with frozen ice cubes. After being installed on the cup holder 400, the first drive motor 200 drives the blade 300 to rotate. The rotation of the blade 300 grinds the ice cubes in the cup body 410 to make ice cream. Furthermore, during the grinding process of the blade 300, the cup holder 400 also moves towards the blade 300, thereby gradually moving the cup body 410 towards the blade 300 to ensure that the blade 300 thoroughly grinds the ice cubes in the cup body 410. It is understood that the cup holder 400 is connected to a drive mechanism, which provides the movement of the cup holder 400.

[0027] In the specific implementation process, the casing forms an installation space. The casing can be a modular assembly structure or a one-piece structure, and the outline shape of the formed installation space can be any shape to meet actual needs. The casing also has an opening for easy access to the cup 410. After the cup 410 is installed on the cup holder 400, the opening is sealed with a cover, protecting the cleanliness of the installation space and reducing noise leakage. Furthermore, in this embodiment, the cup 410 also has a handle, making it easier to pick up and put down the cup 410.

[0028] In this embodiment, the first drive motor 200 is the main heat-generating component and requires effective heat dissipation. The cooling fan 500 can be driven by the first drive motor 200 or connected to a separate drive mechanism to rotate. The rotation of the cooling fan 500 causes airflow within the installation space, forming a cooling airflow that flows past the first drive motor 200. This cooling airflow carries away the heat from the first drive motor 200 and is discharged to the outside of the housing 100 through the heat dissipation holes 110, thus achieving heat dissipation. To reduce the residence time of the cooling airflow within the installation space, in practice, the heat dissipation holes 110 are positioned opposite the cooling fan 500, allowing the cooling airflow to be discharged promptly through them. Furthermore, the cooling airflow also flows through the installation space. Under atmospheric pressure, the cooling airflow carries away heat from the installation space as it is discharged. For example, if a circuit board is located within the installation space, the electronic components on the circuit board will generate heat, as will the heat generated by other components within the installation space. It is also understandable that, under the action of air pressure, on the one hand, the cold air from outside also enters the installation space to achieve airflow, and the airflow in other spaces within the installation space will also flow through the gaps between the structures to achieve heat dissipation.

[0029] This utility model's technical solution utilizes a housing 100 to enclose an installation space for housing a first drive motor 200, a cup holder 400, and a cooling fan 500. The first drive motor 200 connects to a cutting tool 300 and drives it to rotate. A cup body 410 is placed on the cup holder 400, and ice cubes are pre-placed inside the cup body 410. The cup holder 400 and the cutting tool 300 move relative to each other, and the cutting tool 300 rotates to grind the ice cubes. The first drive motor 200 generates a significant amount of heat during the rotation of the cutting tool 300. The cooling fan 500, installed within the installation space, generates a cooling airflow as it rotates. This airflow passes over the first drive motor 200, carrying away its heat and thus dissipating it. The heat-laden airflow is then discharged through the heat dissipation holes 110 to the outside of the housing 100. This ensures timely heat dissipation for the first drive motor 200, improving its cooling efficiency and adaptability to continuous or high-temperature working environments, thereby enhancing its applicability.

[0030] In one embodiment, the first drive motor 200 is connected to a heat sink 600. The heat sink 600 is provided with a heat sink cavity and an air outlet 610 communicating with the heat sink cavity. The heat sink fan 500 is disposed in the heat sink cavity. The heat sink airflow also flows through the heat sink cavity and is discharged through the air outlet 610. The air outlet 610 is disposed facing the heat sink hole 110.

[0031] For details, please refer to Figure 1As shown, the heat sink 600 is fitted onto the outer peripheral wall of one end of the first drive motor 200, forming a heat dissipation cavity within the space near one end of the first drive motor 200. Thus, when the heat dissipation fan 500 rotates, the cooling airflow flows from one end of the first drive motor 200 to the other end and enters the heat dissipation cavity, finally exiting through the air outlet 610. To prevent a large amount of heat-carrying airflow from the first drive motor 200 from entering the installation space, in the specific implementation, the air outlet 610 faces and is positioned opposite the heat dissipation hole 110, and the heat sink 600 is close to the portion of the outer casing 100 with the heat dissipation hole 110, allowing the cooling airflow to exit directly from the air outlet 610 through the heat dissipation hole 110 to the outside of the outer casing 100.

[0032] In one embodiment, the first drive motor 200 includes a housing, the housing having a cavity and an air inlet 210 communicating with the cavity, the cavity also communicating with a heat dissipation cavity to form a heat dissipation channel, and the heat dissipation airflow flowing through the air inlet 210, the heat dissipation channel and the air outlet 610.

[0033] The housing of the first drive motor 200 forms a cavity, and the rotor and stator of the first drive motor 200 are all located within the cavity. It is understood that the heat generated by the first drive motor 200 is mainly concentrated within the cavity. In this embodiment, an air inlet 210 communicating with the cavity is opened on one side wall of the outer casing 100, and the other end is connected to a heat sink 600. The rotation of the cooling fan 500 inside the heat sink 600 causes airflow, and the air in the heat sink cavity is discharged from the air outlet 610. A negative pressure state is created in the heat sink cavity, causing air from the housing to flow into it. To balance the air pressure within the cavity, air from outside the housing enters the cavity through the air inlet 210, thus forming an airflow to carry away the heat within the cavity, achieving heat dissipation for the first drive motor 200. In specific implementations, to improve the heat dissipation effect, multiple air inlets 210 are provided and spaced apart around the outer periphery of the housing.

[0034] refer to Figure 1 As shown, in one embodiment, the housing also has a flow hole 120 communicating with the cavity, and the flow hole 120 is disposed opposite to the air inlet 210. Air with a lower external temperature from outside the housing 100 enters the installation space through the flow hole 120, and further enters the cavity through the air inlet 210. The air inlet 210 is opposite to the flow hole 120 to facilitate the rapid entry of external air into the cavity, thereby improving the smoothness of gas flow.

[0035] refer to Figure 3As shown, in one embodiment, the heat sink 600 is configured as a centrifugal volute. The cross-sectional area of ​​the air outlet 610 of the heat sink 600 gradually increases in the direction away from the heat dissipation cavity. The centrifugal volute, by surrounding the impeller, prevents disorderly gas diffusion, effectively collects the gas discharged from the impeller, and guides the gas to flow in a predetermined direction through the gradually expanding air outlet 610.

[0036] In one embodiment, the first drive motor 200 further includes a drive shaft 220, which is disposed inside the housing. The drive shaft 220 drives and connects to the cutter 300, and one end of the drive shaft 220 extends into the heat dissipation cavity and drives and connects to the heat dissipation fan 500.

[0037] In the specific implementation process, one end of the drive shaft 220 drives the blade 300, and the other end is connected to the cooling fan 500. The cooling fan 500 is driven by the drive shaft 220, which can reduce the number of driving components, save costs, and reduce heat-generating components, which is conducive to heat dissipation and the rational distribution of components. The first drive motor 200 drives the cooling fan 500 to rotate while driving the blade 300 to rotate, so as to dissipate heat. It can be understood that one end of the drive shaft 220 is connected to the transmission component 230, which is connected to the drive shaft 220 to transmit driving force to the drive shaft 220, driving the drive shaft 220 to rotate and grind the ice cubes in the grinding cup 410.

[0038] In one embodiment, a partition 130 is provided in the installation space, a first drive motor 200 is provided in the partition 130, and the other end of the drive shaft 220 passes through the partition 130 and is connected to a transmission assembly 230. The transmission assembly 230 is connected to the tool 300.

[0039] In this embodiment, the partition 130 is located near the top of the installation space, dividing the installation space into a transmission space, within which the transmission assembly 230 is located. The partition 130 also serves to mount and fix the first drive motor 200. Specifically, the first drive motor 200 is fixed to the bottom of the partition 130, with one end passing through the partition 130 and extending into the transmission space to connect to the transmission assembly 230. The cutter 300 is connected to a connecting shaft 310, which passes through the partition 130 and connects to the transmission assembly 230. In specific implementation, the transmission assembly includes a drive wheel, a belt, and a driven wheel. The drive wheel is connected to the drive shaft 220, the driven wheel is connected to the connecting shaft 310, and the belt connects the drive wheel and the driven wheel respectively, thereby realizing power transmission.

[0040] In one embodiment, the heat sink 600 includes a first cover 620, a second cover 630, and a connecting component 640. The first cover 620 and the second cover 630 are disposed opposite to each other and are clamped and surrounded by the connecting component 640 on the outer peripheral wall of the first drive motor 200.

[0041] For easier installation of the heatsink 600, please refer to... Figure 3 As shown, in this embodiment, the heat sink 600 is snapped together with the connecting component 640. The first cover 620 and the second cover 630 of the heat sink 600 are opposite to and clamped to the outer peripheral wall of one end of the first drive motor 200, and are fastened by the connecting component 640. The connecting component 640 can be a snap-fit ​​or bolt structure, etc., and is not limited in this embodiment.

[0042] In one embodiment, the connecting component 640 includes a snap-fit ​​protrusion 641 and a connecting portion 642. One of the first cover 620 and the second cover 630 is provided with the snap-fit ​​protrusion 641, and the other of the two is provided with the connecting portion 642. The connecting portion 642 has a card interface, and the snap-fit ​​protrusion 641 is connected to the card interface.

[0043] In the specific implementation process, in order to improve the stability and effectiveness of the heat sink 600 installation, connecting components 640 are provided on both sides of the first cover 620 and the second cover 630 that are adapted to each other. Specifically, a snap-fit ​​protrusion 641 is provided on the outer peripheral wall of the first cover 620 near the edge, and a corresponding connecting part 642 is provided on the second cover 630. In this embodiment, the connecting part 642 is a buckle adapted to the snap-fit ​​protrusion 641, and the buckle has a snap-fit ​​interface. When the first cover 620 and the second cover 630 are close to each other, the buckle snaps into the snap-fit ​​protrusion 641 through the snap-fit ​​interface, thereby realizing the connection and fixation of the first cover 620 and the second cover 630, and clamping them onto the first drive motor 200.

[0044] To further improve the installation efficiency and convenience of the heat sink 600, in one embodiment, one of the first cover 620 and the second cover 630 is provided with a positioning post 650, and the other is provided with a positioning hole 660, with the positioning post 650 adapted to be inserted into the positioning hole 660.

[0045] In the specific implementation process, the opposite edges of the first cover 620 and the second cover 630 are respectively provided with extension plates, which extend radially and axially. The extension plate of the first cover 620 is provided with positioning holes 660, and the extension plate of the second cover 630 is provided with positioning posts 650. When installing the first cover 620 and the second cover 630, the positioning posts 650 are inserted into the positioning holes 660 to achieve positioning, and then the buckles are engaged with the engaging protrusions 641 to complete the installation of the first cover 620 and the second cover 630.

[0046] refer to Figure 2 and Figure 4As shown, in one embodiment, the ice cream machine further includes a second drive motor 700, which is located within the installation space and driven by the cup holder 400 to move the cup holder 400 toward the blade 300. Specifically, the second drive motor 700 is connected to a worm gear transmission assembly 710, and the worm gear transmission assembly 710 is engaged with a slider 720. The slider 720 has teeth that connect to the worm gear transmission assembly 710. Furthermore, the cup holder 400 is connected to a screw 730, which extends vertically, and the slider 720 is also connected to the cup holder 400. Thus, the second drive motor 700 drives the slider 720 to rotate via the worm gear transmission assembly 710, causing the slider 720 to move along the screw 730, thereby raising and lowering the cup holder 400 to cooperate with the blade 300 in smoothly grinding the ice cubes inside the cup 410.
