Description

Technical Field

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

[0002] In the current ice cream machine technology, most ice cream machines belong to the category of factory processing equipment. However, with consumers paying more attention to food hygiene and safety, home-use ice cream machines are gradually emerging. These machines allow consumers to make their own ice cream at home, ensuring food hygiene and controllable additives, and have become increasingly popular among consumers.

[0003] Existing ice cream machines include a casing, ice cream modules housed within the casing, and a set of refrigeration pipes surrounding the ice cream modules. The ice cream modules comprise multiple ice cream molds arranged side-by-side. The ice cream modules, through the refrigeration pipes, cool and solidify the liquid within the ice cream molds, thus producing ice cream.

[0004] Regarding the aforementioned technologies, the inventors believe that the refrigeration pipes in the ice cream machine are wrapped around the outside of the ice cream molds, that is, wrapped around the outside of multiple ice cream molds, which makes the refrigeration effect in the area between adjacent ice cream molds unsatisfactory, and thus the refrigeration efficiency of the entire ice cream machine needs to be improved. Utility Model Content

[0005] In order to improve the refrigeration efficiency of ice cream machines, this application provides an ice cream machine.

[0006] An ice cream machine includes a housing, an ice cream mold disposed within the inner cavity of the housing, and an evaporator for cooling the ice cream mold. The ice cream mold includes an ice cream forming seat with an upper opening, an ice cream cover for closing the upper opening of the ice cream forming seat, and an ice cream handle installed on the ice cream cover and for extending into the inner cavity of the ice cream forming seat. The evaporator includes evaporators corresponding one-to-one with the ice cream molds and sleeved on the outside of the ice cream forming seat, and a refrigeration unit for providing coolant to the evaporator. A cooling chamber is formed between the evaporator and the ice cream mold. The evaporator has a liquid inlet connector and a liquid outlet connector, both of which are connected to the cooling chamber.

[0007] By adopting the above technical solution, the evaporator is set as an evaporator outside the ice cream mold, and a refrigeration chamber is formed between the evaporator and the ice cream mold. Then, the refrigeration machine provides coolant to the refrigeration chamber, which can refrigerate a single ice cream mold and help improve the refrigeration efficiency of the ice cream machine.

[0008] Optionally, the refrigeration chamber includes multiple refrigeration annular cavities arranged vertically at intervals and a connecting channel connecting two adjacent refrigeration annular cavities; the liquid inlet connector is connected to the uppermost refrigeration annular cavity, and the liquid outlet connector is connected to the lowermost refrigeration annular cavity.

[0009] By adopting the above technical solution, the specific structure of the refrigeration chamber is disclosed. This structure, through multiple vertically spaced refrigeration annular cavities and connecting channels linking adjacent refrigeration annular cavities, allows coolant to enter the refrigeration annular cavity from the inlet connector of the uppermost refrigeration annular cavity, flow within each refrigeration annular cavity, and sequentially flow to the lower refrigeration annular cavities through the connecting channels, finally exiting from the outlet connector of the lowermost refrigeration annular cavity, thereby improving the refrigeration effect on the ice cream mold.

[0010] Optionally, the refrigeration chamber is a spiral chamber, the liquid inlet connector is connected to the upper part of the refrigeration chamber, and the liquid outlet connector is connected to the lower part of the refrigeration chamber.

[0011] By adopting the above technical solution, the specific structure of the refrigeration chamber is disclosed. This structure, by designing the refrigeration chamber as a spiral chamber, allows the coolant to enter the refrigeration ring chamber from the inlet connector of the uppermost refrigeration ring chamber, flow within the spiral refrigeration ring chamber, and exit through the outlet connector of the lowermost refrigeration ring chamber, thereby improving the refrigeration effect on the ice cream mold.

[0012] Optionally, two adjacent connecting channels in the height direction are staggered; the uppermost connecting channel is staggered with the liquid inlet connector; the lowermost connecting channel is staggered with the liquid outlet connector; the two adjacent connecting channels in the height direction are circumferentially spaced 180° apart in the horizontal plane; the uppermost connecting channel and the liquid inlet connector are circumferentially spaced 180° apart in the horizontal plane, and the lowermost connecting channel and the liquid outlet connector are circumferentially spaced 180° apart in the horizontal plane.

[0013] By adopting the above technical solution, the flow path of the coolant in the refrigeration chamber is made longer, thereby extending the residence time of the coolant in the refrigeration chamber, improving refrigeration efficiency, and enhancing the refrigeration effect on the ice cream mold.

[0014] Optionally, the ice cream mold is divided into at least one group of ice cream modules, and the refrigeration chambers in the same group of ice cream modules are arranged in series, and the ice cream modules are connected to the refrigeration unit.

[0015] By adopting the above technical solution, the ice cream mold is divided into at least one group of ice cream molds. The refrigeration chambers in the same group are arranged in series and connected to the refrigeration machine, so that the coolant can flow through each refrigeration chamber in the same group in sequence, thereby improving the refrigeration efficiency and uniformity.

[0016] Optionally, the number of ice cream modules is not less than two sets, and the ice cream modules are arranged side by side.

[0017] By adopting the above technical solution, arranging multiple ice cream modules in parallel can improve ice cream production efficiency and meet more production needs.

[0018] Optionally, a cleaning pipe is connected to the bottom of the ice cream forming base, and a control valve structure is provided at the cleaning pipe to control whether the cleaning pipe is connected or not.

[0019] By adopting the above technical solution, the cleaning pipe can be used to drain the cleaning water after cleaning the ice cream forming station, preventing residual liquid from affecting subsequent ice cream production. The control valve structure can control whether the cleaning pipe is connected or not, facilitating cleaning operations when needed and preventing liquid leakage when not needed, ensuring the normal operation of the ice cream machine.

[0020] Optionally, the cleaning tube includes a first fitting connected to the ice cream forming seat and a second fitting connected to the side wall of the first fitting. The second fitting divides the first fitting into a connecting section connected to the ice cream forming seat and a control section connected to the connecting section. The control valve structure includes a control valve core that is sealed and slidably mounted on the first fitting, an electromagnet structure mounted on the control section, and a control spring that drives the control valve core to always have a tendency to seal the bottom opening of the ice cream forming seat. A magnet block for cooperating with the electromagnet is provided at the bottom of the control valve core.

[0021] The specific structure of the cleaning pipe is disclosed by adopting the above technical solution. In this structure, the bottom of the ice cream forming seat is connected to a first pipe, and the side wall of the first pipe is connected to a second pipe. The second pipe divides the first pipe into a connecting section and a control section. This connection method makes the cleaning path more reasonable. When the ice cream forming seat needs cleaning, the electromagnet structure is energized. The electromagnet interacts with the magnet at the bottom of the control valve core, overcoming the elastic force of the control spring, causing the control valve core to slide within the first pipe, opening the bottom opening of the ice cream forming seat, facilitating water flow to rinse the inside of the ice cream forming seat. After cleaning is completed, the power supply to the electromagnet structure is disconnected, and the control spring drives the control valve core to reset, sealing the bottom opening of the ice cream forming seat, allowing the cleaning water to drain through the second pipe, thus conveniently and quickly completing the cleaning process of the ice cream forming seat.

[0022] Optionally, the housing includes a housing shell and a housing cover that cooperates with the housing shell; the top of the housing cover is provided with an overflow prevention groove, and the bottom surface of the housing cover has a pick-up and put-out opening that corresponds to the ice cream mold; the top surface of the housing cover has an arrangement groove along the edge of the pick-up and put-out opening for arranging the ice cream cover plate; the bottom surface of the housing cover has a limiting plate arranged on the outer side of the top of the ice cream forming base along the edge of the pick-up and put-out opening.

[0023] By adopting the above technical solution, the specific structure of the housing is disclosed. The anti-overflow groove on the top of the housing cover reduces the probability of ice cream liquid overflowing onto the outside of the housing. The pick-up and drop-off ports on the housing cover, which correspond one-to-one with the ice cream molds, facilitate the picking and dropping of the ice cream molds; the arrangement groove along the edge of the pick-up and drop-off ports on the top surface can hold the ice cream cover plate; the limiting plate along the edge of the pick-up and drop-off ports on the bottom surface can limit the outer side of the top of the ice cream forming base, which facilitates the installation of the housing cover.

[0024] Optionally, the inner bottom surface of the housing is provided with a support protrusion for supporting the ice cream forming base. A snap-fit ​​ring groove is circumferentially formed on the top outer wall of the housing; the housing cover has a snap-fit ​​piece that mates with the snap-fit ​​ring groove; support ribs are circumferentially spaced along the inner side of the housing cover, and a positioning gap is formed between the support ribs and the snap-fit ​​piece for insertion into the top side of the housing.

[0025] By adopting the above technical solution, a support protrusion is provided on the bottom surface of the inner shell to support the ice cream forming base, ensuring stable placement of the ice cream forming base within the shell and reducing heat loss. The snap-fit ​​ring groove on the top of the shell engages with the snap-fit ​​piece of the shell cover, enabling a secure connection between the shell and the cover. The positioning gap formed by the inner support rib of the shell cover and the snap-fit ​​piece facilitates insertion of the top side of the shell, achieving accurate positioning and installation of both the shell and the cover.

[0026] In summary, this application includes at least one of the following beneficial technical effects: 1. An ice cream machine, comprising a housing, an ice cream mold disposed within the inner cavity of the housing, and an evaporator for cooling the ice cream mold; by configuring the evaporator as an evaporator fitted outside the ice cream mold, and forming a cooling chamber between the evaporator and the ice cream mold, and then supplying coolant to the cooling chamber by a refrigeration unit, it is possible to cool a single ice cream mold, thereby improving the cooling efficiency of the ice cream machine; 2. Divide the ice cream mold into at least one group of ice cream molds. The refrigeration chambers in the same group are arranged in series and connected to the refrigeration machine, so that the coolant can flow through each refrigeration chamber in the same group in sequence, thereby improving the refrigeration efficiency and uniformity. 3. A cleaning pipe with a control valve is installed at the bottom of the ice cream forming station. The cleaning pipe can be used to drain the cleaning water after cleaning the ice cream forming station, avoiding residual liquid from affecting the subsequent ice cream making. The control valve structure can control whether the cleaning pipe is connected or not, making it convenient to perform cleaning operations when needed and preventing liquid from flowing out when not needed, ensuring the normal operation of the ice cream machine.

[0036] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0037] Example 1 This application discloses an ice cream machine. (Refer to...) Figure 1 and Figure 2 An ice cream machine includes a housing 1, an ice cream mold 2 disposed inside the housing 1, and a cooling component for cooling the ice cream mold 2.

[0038] Reference Figure 2 and Figure 3The ice cream mold 2 includes an ice cream forming base 21 with an open top, an ice cream cover 22 for closing the upper opening of the ice cream forming base 21, and an ice cream stem 23 installed on the ice cream cover 22 and extending into the inner cavity of the ice cream forming base 21. The ice cream forming base 21 is made of a metal material with good thermal conductivity, such as aluminum alloy, which can better improve cooling efficiency. The ice cream cover 22 is made of plastic, which is lightweight and easy to process. The ice cream stem 23 is made of plastic, and the stem section extending into the inner cavity of the ice cream forming base 21 has several first circular through holes 231 evenly distributed axially. During the ice cream forming process, the liquid raw material solidifies through the through holes to form an icicle interlocking structure, which enhances the fixing strength between the ice cream and the stem through mutual interlocking, effectively preventing it from falling off. In this embodiment, the number of first circular through holes 231 is three. Multiple parallel anti-slip ridges 232 are axially arranged on the surface of the stem section exposed outside the ice cream cover 22, increasing the friction coefficient and improving handheld stability.

[0039] Reference Figure 2 and Figure 4 The refrigeration assembly includes an evaporator 31 that corresponds one-to-one with the ice cream mold 2 and is sleeved on the outside of the ice cream forming base 21, and a refrigeration machine (not shown in the figure) that provides coolant to the evaporator 31. A refrigeration chamber 32 is formed between the evaporator 31 and the ice cream mold 2. The evaporator 31 has a liquid inlet connector 321 and a liquid outlet connector 322, both of which are connected to the refrigeration chamber 32.

[0040] Reference Figure 2 and Figure 4 The cooling chamber 32 can be composed of multiple vertically spaced cooling ring chambers 323, with adjacent cooling ring chambers 323 connected by a connecting channel 324. The liquid inlet connector 321 is connected to the uppermost cooling ring chamber 323, and the liquid outlet connector 322 is connected to the lowermost cooling ring chamber 323. In this way, the coolant enters from the uppermost side, flows sequentially through each cooling ring chamber 323, and finally flows out from the lowermost side, achieving overall cooling of the ice cream forming base 21. Adjacent connecting channels 324 in the vertical direction are staggered; the uppermost connecting channel 324 is staggered with the liquid inlet connector 321, and the lowermost connecting channel 324 is staggered with the liquid outlet connector 322. In this embodiment, the two adjacent connecting channels 324 in the height direction are circumferentially spaced 180° apart in the horizontal plane. The uppermost connecting channel 324 and the liquid inlet connector 321 are circumferentially spaced 180° apart in the horizontal plane. The lowermost connecting channel 324 and the liquid outlet connector 322 are circumferentially spaced 180° apart in the horizontal plane.

[0041] Reference Figure 4The cooling chamber 32 can also be composed of a spiral cavity that extends continuously from bottom to top. The liquid inlet connector 321 is connected to the upper part of the cooling chamber 32, and the liquid outlet connector 322 is connected to the lower part of the cooling chamber 32, which allows the coolant to flow a longer and more uniform path in the cooling chamber 32, thereby improving the cooling effect on the ice cream mold 2.

[0042] Reference Figure 2 and Figure 4 The ice cream mold 2 is divided into at least one group of ice cream molds. The number of ice cream molds 2 in each group can be one, two, three, or more. In this embodiment, the ice cream mold 2 is divided into two groups of ice cream molds, and the number of ice cream molds 2 in each group is two. The refrigeration chambers 32 in the same group of ice cream molds are connected in series, and both groups of ice cream molds are connected to the refrigeration unit and arranged in parallel.

[0043] Reference Figure 2 and Figure 4 Series connection refers to connecting the cooling chambers 32 of the same ice cream module so that the refrigerant generated by the refrigeration unit can sequentially pass through the cooling chambers 32 of the same ice cream module; parallel connection refers to the independent circulation of the refrigerant in the ice cream module so that the two ice cream modules can be activated independently. In this embodiment, two adjacent ice cream modules are connected to the refrigeration unit through a T-tube.

[0044] Reference Figure 1 and Figure 5 The housing 1 includes a housing shell 11 and a housing cover 12 that mates with the housing shell 11. The top of the housing cover 12 is provided with an overflow groove 121. The bottom surface of the housing cover 12 has a loading / unloading opening 126 corresponding to the ice cream mold 2, allowing operators to add ingredients or remove formed ice cream through the loading / unloading opening 126. The top surface of the housing cover 12 has an arrangement groove 122 along the edge of the loading / unloading opening for arranging the ice cream cover plate 22. The arrangement groove 122 positions the ice cream cover plate 22, ensuring it accurately fits onto the ice cream forming base 21. The bottom surface of the housing cover 12 has a limiting plate 123 along the edge of the loading / unloading opening 126, positioned on the outer side of the top of the ice cream forming base 21. The limiting plate 123 further ensures the accurate installation position of the ice cream forming base 21.

[0045] Reference Figure 5 The outer top wall of the housing 11 has a circumferentially formed snap-fit ​​groove 111. The housing cover 12 has a snap-fit ​​piece 124 that mates with the snap-fit ​​groove 111. The snap-fit ​​piece 124 engages within the snap-fit ​​groove 111 to connect the housing cover 12 and the housing 11. Support ribs 125 are circumferentially spaced along the inner side of the housing cover 12. A positioning gap is formed between the support ribs 125 and the snap-fit ​​piece 124 for insertion of the top side of the housing 11, facilitating alignment during insertion and making installation more convenient.

[0046] Reference Figure 6 The inner bottom surface of the housing 1 is provided with a support protrusion 113 for supporting the ice cream forming base 21. A second circular through hole 114 is also provided at the center of the inner bottom surface of the housing 1 for the refrigeration pipe of the refrigeration machine to pass through.

[0047] The implementation principle of an ice cream machine according to an embodiment of this application is as follows: An ice cream machine includes a housing 1, an ice cream mold 2 arranged in the inner cavity of the housing 1, and a refrigeration component for cooling the ice cream mold 2; by setting the refrigeration component as an evaporator 31 sleeved on the outside of the ice cream mold 2, and forming a refrigeration chamber 32 between the evaporator 31 and the ice cream mold 2, and then providing coolant to the refrigeration chamber 32 by a refrigeration machine, a single ice cream mold 2 can be cooled, which helps to improve the refrigeration efficiency of the ice cream machine.

[0048] Example 2 Compared with Example 1, this embodiment is identical to the ice cream machine in Example 1 except that a cleaning pipe 28 with a control valve structure is provided at the bottom of the ice cream forming base 21.

[0049] Reference Figure 7 and Figure 8 In order to facilitate cleaning of the inner cavity of the ice cream forming base 21, a cleaning pipe 28 is provided at the bottom of the ice cream forming base 21, and a control valve structure is provided at the cleaning pipe 28 to control whether the cleaning pipe 28 is connected or not.

[0050] Reference Figure 7 and Figure 8 The cleaning pipe 28 includes a first pipe fitting 281 and a second pipe fitting 282 connected to the side wall of the first pipe fitting 281. Both the first pipe fitting 281 and the second pipe fitting 282 are made of aluminum alloy. The second pipe fitting 282 divides the first pipe fitting 281 into a connecting section 2811 connected to the ice cream forming base 21 and a control section 2812 connected to the connecting section 2811.

[0051] Reference Figure 7 and Figure 8 The control valve structure includes a control valve core 2831 that is slidably mounted on the first pipe 281, an electromagnet 2832 mounted on the control section 2812, and a control spring 2833 that drives the control valve core 2831 to always have a tendency to seal the bottom opening of the ice cream forming seat 21. A magnet block 2835 for cooperating with the electromagnet 2832 is provided at the bottom of the control valve core 2831, and a sealing gasket 2834 is provided between the control valve core 2831 and the bottom opening of the ice cream forming seat 21.

[0052] During normal ice cream making, the control spring 2833 seals the bottom opening of the ice cream forming seat 21 with the control valve core 2831 to prevent material leakage. When cleaning the ice cream forming seat 21 is required, the electromagnet 2832 is energized. The electromagnet 2832 interacts with the magnet 2835 at the bottom of the control valve core 2831, overcoming the elastic force of the control spring 2833, causing the control valve core 2831 to slide within the first pipe 281. This connects the first pipe 281 and the second pipe 282, allowing cleaning water to drain through the second pipe 282. In this embodiment, the second pipe 282 is connected to an external drain pipe so that cleaning water can be discharged from the ice cream machine.

[0053] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
