[0024] In order to make the purpose and technical solution of the utility model clearly and completely described, and the advantages more clearly understood, the embodiments of the utility model are further described in detail below with reference to the accompanying drawings.

[0025] In the description of the present invention, it should be noted that the terms "center", "middle", "upper", "lower", "left", "right", "inside", "outside", "top", "bottom", "side", "vertical", "horizontal", "first", "second", etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0026] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] refer to Figure 1 , Figure 2 and Figure 3 A food processor includes a main unit 1 and a mixing cup 2, wherein the mixing cup 2 is detachably mounted on the main unit 1. The mixing cup 2 is used to hold food materials, and is provided with a mixing blade assembly 201 therein. The main unit 1 is provided with a driving motor 101, and the mixing blade assembly 201 is driven by the driving motor 101 to rotate at a high speed to crush and beat the food materials in the mixing cup 2. Usually, a heating assembly (not shown) is also provided in the food processor to heat the food materials in the mixing cup 2 to make edible food.

[0028] The blending cup 2 includes an inner cup body 21 and a cup sleeve 22. The cup sleeve 22 is sleeved on the inner cup body 21 from the bottom end of the inner cup body 21, so that the inner cup body 21 is at least partially contained in the cup sleeve 22. The upper end of the cup sleeve 22 is fixedly connected to the inner cup body 21. There is a first gap between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22. There is a second gap between the bottom wall of the inner cup body 21 and the bottom wall of the cup sleeve 22, so that a cavity 23 is defined between the inner cup body 21 and the cup sleeve 22. The cavity 23 is provided with a first opening 231 and a second opening 232. The host 1 is provided with a cooling air duct 103. When the blending cup 2 and the host 1 are assembled, one end of the cooling air duct 103 is connected to the first opening 231, and the other end is connected to the external environment. A fan 104 is installed in the cooling air duct 103. When the fan 104 is working, it drives air to enter the cavity 23 from the second opening 232. The air flow contacts the outer wall of the inner cup body 21 during the flow in the cavity 23 to exchange heat, and then flows out from the first opening 231 through the cooling air duct 103, thereby accelerating the cooling speed of the food in the blender cup 2 and reducing the waiting time of the user. It can be understood that the direction of the air inlet and outlet of the fan 104 can be reversed so that the air enters the cavity 23 from the cooling air duct 103 through the first opening 231 and then flows out from the second opening 232, which can also have a cooling effect on the inner cup body 21.

[0029] In a specific embodiment, the first opening 231 is opened at the bottom of the cavity 23, the second opening 232 is opened at the upper part of the cavity 23, and the upper surface of the main unit 1 is provided with a connecting port 102. When the blending cup 2 and the main unit 1 are assembled, the first opening 231 is connected to the heat dissipation duct 103 through the connecting port 102.

[0030] refer to Figure 2 , the depth of the inner cup body 21 inserted into the cup sleeve 2 is h, and the total depth of the inner cup body 21 is H, then the conditions are met: The function of the cup sleeve 22 is to form a cavity 23 with the inner cup body 21, so that the flowing air can exchange heat with the outer wall of the inner cup body 21. It can be understood that at the same flow rate, the longer the air acts on the outer wall of the inner cup body 21, the more heat it takes away.

[0031] Specifically, when When the inner cup body 21 is completely contained in the cup sleeve 22, the air flow can act from the top of the inner cup body 21 to the bottom of the inner cup body 21, and the acting distance is the longest and the time is the longest. At this time, the cooling effect is the best. If H remains unchanged, gradually reduce h, for example At this time, the inner cup body 21 is still mostly covered by the cup sleeve 22, and the air flow can still act on the inner cup body 21 for a long time when flowing through the cavity 23, and the cooling effect is better. When the inner cup body 21 is only partially covered by the cup sleeve 22, the air flow enters the cavity 23 from the second opening 232 and then flows out from the first opening 231. The contact time with the inner cup body 21 is too short, and the cooling effect is poor.

[0032] Continue to refer Figure 2 The first gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22 is d, which satisfies the condition: 3mm≤d≤20mm. By adjusting the size of d, the flow area of ​​the air flow can be adjusted to improve the cooling effect.

[0033] When the power of the fan 104 is constant, the flow rate of the air flow is inversely proportional to the gap distance d. The larger the gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22, the slower the flow rate of the air flow in the cavity 23. The smaller the gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22, the faster the flow rate of the air flow. Specifically, if d>20mm, although the flow rate of the air flow in the cavity 23 is slow, due to the excessive gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22, only a small part of the air flow can interact with the outer wall of the inner cup body 21, and the rest of the air flow directly flows out from the second opening without heat exchange with the inner cup body 21, and the cooling effect is poor. Gradually reduce the gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22, for example, d = 15mm. At this time, the flow rate of the air flow is faster, and because the gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22 is moderate, the air flow flowing into the cavity 23 can exchange heat with the inner cup body 21 very well, and the cooling effect is better. Continue to reduce the gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22, for example, d = 8mm. At this time, the cross-sectional area of ​​the air flow is small, which has affected the air volume of the fan 104, and the cooling efficiency is relatively low, and the cooling effect is also affected to a certain extent. Further reduce the gap distance between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22, for example, d = 3mm. At this time, the cross-sectional area of ​​the air flow is too small, which seriously reduces the air volume entering the cavity 23, so the cooling effect is poor. Optionally, the gap distance d between the outer wall of the inner cup body 21 and the inner wall of the cup sleeve 22 may also satisfy: 5mm≤d≤15mm, thereby further improving the cooling effect. More preferably, 8mm≤d≤15mm.

[0034] In order to speed up the cooling efficiency of high-temperature food, the inner cup body 21 can be made of a material with good thermal conductivity, such as a metal cup body. In practical applications, when processing food, the inner cup body 21 is usually not filled too full. Figure 2 In the present application, the inner cup body 21 includes an upper cup body 211 and a lower cup body 212. The upper cup body 211 is made of glass, and the lower cup body 212 is made of metal such as aluminum and stainless steel. The cup sleeve 22 is mounted on the lower cup body 212, which ensures the cooling effect while taking into account the production cost.

[0035] Furthermore, the outer wall of the lower cup body 212 is provided with heat dissipation ribs 213 , and the heat dissipation ribs 213 can increase the contact area between the air flow and the lower cup body 212 , thereby further improving the cooling efficiency.

[0036] refer to Figure 2 A semiconductor refrigeration sheet 214 is also provided on the outer wall of the lower cup body 212. The cooling end of the semiconductor refrigeration sheet 214 is attached to the outer wall of the lower cup body 212. When the semiconductor refrigeration sheet 214 is working, the low temperature generated by the cooling end can quickly exchange heat with the outer wall of the lower cup body 212. At the same time, the heat generated by the heating end of the semiconductor refrigeration sheet 214 is carried out of the cavity 23 by the air flow, further accelerating the cooling speed of the food.

[0037] In some embodiments, in order to maximize the amount of air entering the cavity 23, a plurality of second openings 232 are provided; the plurality of second openings 232 are evenly arranged at the top of the outer wall of the cup sleeve 22, so that the airflow entering the cavity 23 is evenly distributed, thereby being able to evenly cool down all parts of the lower cup body 212.

[0038] Since the second opening 232 is connected to the cooling air duct 103 in the main unit 1, a waterproof shutter is provided at the second opening 232 to prevent water from entering the main unit 1 from the second opening 232. In addition, a waterproof baffle 105 is provided at the connecting opening 102. When the blending cup 2 is not mounted on the main unit 1, the waterproof baffle 105 can prevent water from entering the cooling air duct 103 from the connecting opening 102.

[0039] In some embodiments, a temperature sensor (not shown) is provided at the bottom of the lower cup body 212, and the temperature sensor is connected to a controller on the host 1. When the food drops to a set temperature, the controller turns off the fan 104 to prevent the food temperature from dropping too low.

[0040] It should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
