[0028] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0029] See also Figure 1 , Figure 4 , Figure 5 and Figure 6 The ice cream machine 100 of the present invention comprises a housing 10, a pot 20, a refrigeration device 30, a heat sink 40, a fan 50 and an air duct control frame 70. The pot 20, the refrigeration device 30, the heat sink 40 and the fan 50 are installed in the housing 10 so that they are built into the housing 10 and protected by the housing 10. Figure 1 and the housing 10 is provided with a cold air inlet 11 and a hot air outlet 12 which are separated from each other.

[0030] At the same time, the refrigeration device 30 is arranged to surround the pot body 20 to meet the needs of the refrigeration device 30 for cooling and heat preservation of the pot body 20; the pot body 20 is also exposed to the outside from the top of the shell 10. The heat sink 40 and the refrigeration device 30 are stacked, and the fan 50 and the heat sink 40 are stacked, so that the heat sink 40 is located between the refrigeration device 30 and the fan 50. Figure 6 as shown; optionally, Figure 6 As an example, the fan 50, the heat sink 40 and the refrigeration device 30 are sequentially stacked along the direction from front to back of the housing 10. Obviously, according to actual needs, the fan 50, the heat sink 40 and the refrigeration device 30 can also be sequentially stacked along the direction from back to front of the housing 10. Figure 6 Limits shown.

[0031] Furthermore, a gap 60 is defined between the heat sink 40 and the housing 10. Figure 5 as shown; optionally, Figure 6 In the embodiment, the heat sink 40 defines a gap 60 with the left side, right side, upper side and lower side of the housing 10. The air duct control frame 70 is arranged to surround the heat sink 40. The air duct control frame 70 is located between the heat sink 40 and the housing 10 and closes the gap 60. Figure 4 As shown; the air duct control frame 70 has a control channel 71 for the gas blown by the fan 50 to the heat sink 40 to be discharged from the hot air outlet 12 of the housing 10; optionally, in combination with Figure 4 , Figure 6 and Figure 7As an example, the control channel 71 is respectively arranged at the left and right sides of the air duct control frame 70, and correspondingly, the hot air outlet 12 is respectively located at the left and right sides of the shell 10, so as to meet the need of the hot air outlet 12 on the same side being connected to the control channel 71, so as to effectively increase the hot air outlet volume of the hot air outlet 12; obviously, according to actual needs, the hot air outlet 12 can also be located on the left or right side of the shell 10; when the hot air outlet 12 is located on the left or right side of the shell 10, at this time, the control channel 71 is correspondingly arranged at the left or right side of the air duct control frame 70, so it is not necessary to Figure 4 , Figure 5 and Figure 6 More specifically, as follows:

[0032] like Figure 7 and Figure 8 As shown, as an example, an embedding cavity 72 for embedding and assembling the heat sink 40 is provided on the air duct control frame 70, so as to meet the need that the heat sink 40 assembled in the embedding cavity 72 is surrounded by the air duct control frame 70. The cavity opening 721 of the embedding cavity 72 faces the refrigeration device 30, so as to meet the need that the heat sink 40 assembled in the embedding cavity 72 can also maintain surface contact with the refrigeration device 30. The left cavity wall 722 and the right cavity wall 723 of the embedding cavity 72 each have a connecting port 7221 (7231) communicating with the embedding cavity 72, that is, the left cavity wall 722 has a connecting port 7221 communicating with the embedding cavity 72, and the right cavity wall 723 has a connecting port 7231 communicating with the embedding cavity 72, so that the control channel 71 is connected with the embedding cavity 72 via the connecting port 7221 (7231). The rear cavity wall 724 of the embedding cavity 72 facing the fan 50 is provided with an alignment opening 7241 communicating with the embedding cavity 72. The alignment opening 7241 is aligned with the fan 50 to meet the requirement that the cold air sucked by the fan 50 first passes through the alignment opening 7241 and then blows toward the heat sink 40. Specifically, Figure 7 , Figure 8 and Fig. 9 As an example, the left side cavity wall 722 of the embedded cavity 72 extends to the left and is separated from the first left baffle 7222 and the second left baffle 7223 in the front-to-back direction of the air duct control frame 70. The first left baffle 7222, the second left baffle 7223 and the left cavity wall 722 jointly define a control channel 71, that is, the control channel 71 is located on the left side of the air duct control frame 70. The right side cavity wall 723 of the embedded cavity 72 extends to the right and is separated from the first right baffle 7232 and the second right baffle 7233 in the front-to-back direction of the air duct control frame 70. The first right baffle 7232, the second right baffle 7233 and the right cavity wall 723 jointly define another control channel 71, that is, the control channel 71 is located on the right side of the air duct control frame 70. See the state. Figure 8 and Fig. 9To meet the need of connecting the hot air outlet 12 on the same side to the control channel 71. In addition, for a more detailed structural description of the air duct control frame 70, see the following description:

[0033] like Fig. 9 As shown, as an example, the first left baffle plate 7222 and the second left baffle plate 7223 are arranged obliquely in a direction away from the left cavity wall 722 in a manner of expanding the distance between the first left baffle plate 7222 and the second left baffle plate 7223; such a design can expand the control channel 71 at the left side of the air duct control frame 70, so that the hot air outlet 12 on the left side of the shell 10 occupies more space, and the hot air outlet volume on the left side of the shell 10 can be further increased. In addition, the first right baffle plate 7232 and the second right baffle plate 7233 are arranged obliquely in a direction away from the right cavity wall 723 in a manner of expanding the distance between the first right baffle plate 7232 and the second right baffle plate 7233; such a design can expand the control channel 71 at the right side of the air duct control frame 70, so that the hot air outlet 12 on the right side of the shell 10 occupies more space, and the hot air outlet volume on the right side of the shell 10 can be further increased. Specifically, combined with Figure 6 and Figure 7 As an example, the first left baffle plate 7222 and the first right baffle plate 7232 are respectively arranged adjacent to the refrigeration device 30, the second left baffle plate 7223 and the second right baffle plate 7233 are respectively arranged adjacent to the fan 50, the inclination angle of the first left baffle plate 7222 is smaller than the inclination angle of the second left baffle plate 7223, and the inclination angle of the first right baffle plate 7232 is smaller than the inclination angle of the second right baffle plate 7233; such a design is more conducive to the cold air entering from the cold air inlet 11 to converge to the center of the fan 50. In addition, an upper baffle 7251 is extended upward from the upper cavity wall 725 of the embedded cavity 72, and a lower baffle 7261 is extended downward from the lower cavity wall 726 of the embedded cavity 72; with the help of the left baffle (i.e., the first and second left baffles), the right baffle (i.e., the first and second right baffles), the upper baffle 7251 and the lower baffle 7261, the gap 60 between the heat sink 40 and the shell 10 is closed on the left, right, top and bottom sides, thereby simplifying the specific structure of the air duct control frame 70 to close the gap 60 between the heat sink 40 and the shell 10 from the left, right, top and bottom sides.

[0034] like Figure 4 , Figure 5 and Fig.10As shown, as an example, the heat sink 40 includes a heat sink base 41 and a plurality of heat sink guide fins 42 extending along the left and right directions of the heat sink base 41, all the heat sink guide fins 42 are arranged in a spaced relationship in the upper and lower directions of the heat sink base 41, the heat sink base 41 and all the heat sink guide fins 42 jointly define a heat sink channel 43, the outlet 431 of the heat sink channel 43 is connected to the connecting port 7221 (7231), and the inlet 432 of the heat sink channel 43 is aligned with the alignment opening 7241; to meet the need of "the fan 50 allows cold air to pass through the alignment opening 7241 and enter the heat sink channel 43 from the inlet 432 of the heat sink channel 43, and then be discharged from the outlet 431 of the heat sink channel 43, so that the exhausted hot air passes through the connecting port 7221 (7231) and enters the control channel 71, and is finally discharged from the hot air outlet 12 to the outside of the shell 10".

[0035] like Figure 1 , Figure 2 , Figure 6 and Figure 7 As shown, as an example, the cold air inlet 11 is located at the front side of the shell 10. Obviously, according to actual needs, the cold air inlet 11 can also be located at the rear side of the shell 10. When the cold air inlet 11 is located at the rear side of the shell 10, the refrigeration device 30 and the pot body 20 need to be arranged closer to the front side of the shell 10; similarly, when the cold air inlet 11 is located at the front side of the shell 10, the refrigeration device 30 and the pot body 20 need to be arranged closer to the rear side of the shell 10. In addition, the cold air inlet 11 and the hot air outlet 12 are each composed of a plurality of holes arranged in a matrix. Figure 1 , Figure 2 , Figure 6 and Figure 7 In addition, Figure 2 As an example, an operating space 131 is provided on the bottom 13 of the shell 10, and the operating space 131 forms a hand-held structure 132 corresponding to the bottom 131 of the shell 10; such a design facilitates the operator to clean the ice cream machine 100 of the utility model, that is, when cleaning, the operator can grasp the shell 10 from the bottom 13 of the shell 10 by holding the hand-held structure 132, thereby facilitating the operator to clean the ice cream machine 100 of the utility model.

[0036] Compared with the prior art, the ice cream machine 100 of the utility model further includes an air duct control frame 70 arranged to surround the heat sink 40 and located between the heat sink 40 and the shell 10, the air duct control frame 70 closes the gap 60, and the air duct control frame 70 has a control channel 71 for the gas blown onto the heat sink 40 by the fan 50 to be discharged from the shell 10 through the hot air outlet 12; such a design allows the cold air outside the shell 10 to be sucked in from the cold air inlet 11 under the action of the fan 50 and then blown toward the heat sink 40, so as to take away the heat on the heat sink 40 to form hot air, and the hot air can only be discharged from the hot air outlet 12 outside the shell 10 through the control channel 71; therefore, interference between cold air and hot air and the influence of hot air flowing from the gap 60 to the refrigeration device 30 on the refrigeration device 30 can be avoided.

[0037] It is worth noting that, since the specific structures of the refrigeration device 30, the pot body 20, the fan 50 and the housing 10 are well known in the art, they will not be described in detail here.

[0038] The above disclosure is only a preferred example of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
