Description

Technical Field

[0001] The present invention relates to the technical field of cold drink manufacturing equipment, in particular to a cold drink equipment. Background Art

[0002] Smoothie making equipment is a common cold drink processing equipment, which is widely used in cold drink shops, restaurants, home kitchens and other places. Existing smoothie making equipment is generally used to make smoothies, which are cold drinks with large ice crystals and a rough taste. Existing smoothie making equipment usually uses a cylinder to contain and store raw materials and smoothies. After the raw materials are poured into the cylinder, the evaporator of the refrigeration component freezes the raw materials so that the raw materials gradually form ice crystals. During this process, the stirring element of the stirring component stirs the raw materials being frozen to form a smoothie with distinct particles. During the stirring process, the smoothie continues to move in the cylinder. Since the inside of the cylinder is closed, the smoothie moving with the stirring element will gradually move to the front end of the cylinder. Driven by the extrusion force, the smoothie will reflux from the front end of the cylinder to the rear end. This reflux can ensure the normal stirring. However, existing smoothie making equipment is unable to produce ice cream products with smaller ice crystals and delicate taste. One reason is that the particles of ice cream products are smaller and easier to hide in tiny corners, while the front end of the cylinder of the smoothie making equipment is usually right-angled or flat, and there is no corresponding guide structure. Ice cream products with smaller ice crystals are easily retained at the front end of the cylinder, making it difficult to produce a normal reflux cycle, which in turn affects the subsequent mixing efficiency.

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0037] See also Figure 1 and Figure 2 The embodiment of the present invention discloses a cold drink device, including a shell component 5, a refrigeration component 3, a stirring component 4 and a material inlet and outlet component 10. The shell component 5 includes a chassis 51, and the chassis 51 serves as the basic support structure of the entire cold drink device. The refrigeration component 3 includes an evaporator 31. Raw materials such as milk and beverages can exchange heat in the evaporator 31. The evaporator 31 absorbs heat and can freeze the raw materials into ice crystals. The stirring component 4 includes a stirring drive 41 and a stirring member 42. The stirring member 42 surrounds the periphery of the evaporator 31 and can push and stir the solid-liquid mixture formed by the raw materials on the surface and periphery of the evaporator 31, so that the raw materials form a solid-liquid mixture with smaller particles. The stirring drive 41 is connected to the stirring member 42 in a transmission manner, and the stirring drive 41 is preferably a rotary motor, a variable speed DC motor, etc.

[0038] The material inlet and outlet assembly 10 includes a barrel 1 and a discharge mechanism 2 arranged at one end of the barrel 1. The barrel 1 can accommodate raw materials for making cold drinks and the formed solid-liquid mixture. The barrel 1 is provided with a feed port 111, and the raw materials can be poured in from the feed port 111. The barrel 1 is covered on the periphery of the evaporator 31. A storage space 12 is formed between the barrel 1 and the evaporator 31. The raw materials and the formed solid-liquid mixture will move in the storage space 12. The stirring drive member 41 can drive the stirring member 42 to rotate and stir in the storage space 12.

[0039] In order to facilitate the formed product to flow at the front end of the cylinder 1, the cylinder 1 also includes a guide portion 13, which is arranged at one end of the cylinder 1 close to the discharge assembly, that is, the front end of the cylinder 1. Under the guiding effect of the guide portion 13, the formed product can flow from the side of the discharge assembly to the upper part of the cylinder 1 without affecting the product flowing from the middle of the cylinder 1 to the discharge assembly, and under the continuous extrusion force, the product located at the guide portion 13 can continue to flow back from the upper part of the cylinder 1 to the middle part, thereby forming a cycle. Ice cream with smaller particles is easy to stay in smaller corners, but because the inner wall of the guide portion 13 forms an inner concave surface, the connection between the inner concave surface and the cylinder 1 is less likely to produce a hidden angle than the connection between the plane and the cylinder 1, so it is more conducive to the smooth flow of ice cream with smaller ice crystal particles. Therefore, the cold drink equipment of the present invention can be applied to products such as smoothies and ice cream at the same time. Preferably, the outer contour of the cross section of the cylinder 1 is at least partially circular, elliptical or quasi-elliptical. Quasi-ellipse refers to a closed curve figure with the concept of a major axis and a minor axis but different from a standard ellipse in terms of edge curvature, symmetry, etc.

[0040] The beneficial effects of the embodiments of the present invention are as follows:

[0041] The cold drink equipment of the embodiment of the present invention is provided with a refrigeration component 3, a stirring component 4 and an inlet and outlet component 10, wherein the refrigeration component 3 includes an evaporator 31, the stirring component 4 includes a stirring member 42, and the inlet and outlet component 10 includes a barrel 1, wherein the barrel 1 is covered on the periphery of the evaporator 31, and raw materials such as milk and beverages can be poured into the barrel 1, wherein the evaporator 31 freezes and exchanges heat with the raw materials, and the stirring member 42 stirs the raw materials or the formed solid-liquid mixture during the freezing process, and during the stirring process, the solid-liquid mixture moves to the front end of the barrel 1, and in order to enable the solid-liquid mixture at the front end of the barrel 1 to reflux smoothly, the barrel 1 also includes a guide portion 13, wherein the guide portion 13 can guide the solid-liquid mixture of small particles to move upward to the upper part of the barrel 1, and move obliquely to the middle part of the barrel 1, thereby completing the reflux, thereby improving the stirring efficiency.

[0042] Specifically, the guide portion 13 is gradually inclined from the upper part of the cylinder 1 toward the direction of the discharging assembly, and the inner wall of the guide portion 13 forms an inner concave surface. The joint between the inner concave surface and the cylinder 1 is less likely to produce a hidden angle than the joint between a plane and the cylinder 1, and is therefore more conducive to the smooth flow of ice cream with smaller ice crystals.

[0043] A transition connection portion 16 is provided between the outer wall of the cylinder 1 and the feed port 111. The transition connection portion 16 is used to form a transition connection between the feed port 111 and the cylinder 1. The transition connection portion 16 gradually extends from the outer wall of the cylinder 1 toward the feed port 111. After the raw material is frozen to form a solid-liquid mixture, the solid-liquid mixture can be accommodated in the transition connection portion 16 and gradually stirred and pushed from the transition connection portion 16. The solid-liquid mixture can be pushed to the discharge port 121. The provision of the transition connection portion 16 can increase the accommodating volume on the one hand, and can facilitate the reflux of the solid-liquid mixture from the upper part of the cylinder 1 on the other hand.

[0044] The inner wall of the guide portion 13 is a concave continuous curved surface. The concave continuous curved surface allows the smoothie and ice cream to smoothly flow back toward the upper part of the cylinder 1 at the position of the discharge assembly, which is beneficial to the reflux of the solid-liquid mixture and forms a circulation of the solid-liquid mixture in the cylinder 1.

[0045] In some embodiments, the transition connection portion 16 is an arc transition or an inclined transition. The shape of the arc transition or the inclined transition can enable the solid-liquid mixture to smoothly move from the position of the feed port 111 to the middle of the cylinder 1, and gradually move to the vicinity of the discharge port 121. Furthermore, the surface of the transition connection portion 16 can be a smooth curved surface, which can reduce the friction of the solid-liquid mixture in the transition connection portion 16, thereby facilitating the movement of the solid-liquid mixture in the transition connection portion 16 and facilitating stirring and pushing of the material, and on the other hand, reducing the occurrence of heaping and retention of the solid-liquid mixture in the transition connection portion 16.

[0046] In some embodiments, the width of the transition connection portion 16 gradually increases from the outer wall of the cylinder 1 toward the feed port 111, and the transition connection portion 16 forms a gradually concentrated channel in the direction away from the feed port 111 to facilitate the solid-liquid mixture to move to the middle of the cylinder 1.

[0047] In an embodiment of the present invention, the outer contour of the cross section of the cylinder 1 is a closed contour composed of regular or irregular smooth curves. The closed contour composed of smooth curves can reduce the friction of the solid-liquid mixture on the inner wall of the cylinder 1, thereby reducing the occurrence of pile-up, retention, etc., which is conducive to uniform stirring and improves the stirring effect.

[0048] See also Figure 2 and Figure 3A side end surface 14 is provided at one end of the cylinder 1 close to the discharge component, the discharge component is arranged on the side end surface 14, and the discharge port 121 is arranged on the side end surface 14. The squeezed solid-liquid mixture will be concentrated on the side end surface 14, and the upper part of the side end surface 14 is connected to the lower part of the guide portion 13. In this embodiment, the upper part of the side end surface 14 is tangentially connected to the lower part of the guide portion 13, and along the connection between the side end surface 14 and the guide portion 13, the solid-liquid mixture can be smoothly transferred from the side end surface 14 to the upper part of the cylinder 1, wherein the phase connection line between the side end surface 14 and the guide portion 13 is a first phase connection line 141, and the solid-liquid mixture produces a first turn in the first phase connection line 141, so that the solid-liquid mixture can be transferred from the side end surface 14 to the upper part of the cylinder 1.

[0049] The side wall of the cylinder 1 is provided with a cylinder surface 15, and the cylinder surface 15 is the main side wall of the cylinder 1, wherein the cylinder surface 15 is connected to the upper part of the guide part 13. In the present embodiment, the cylinder surface 15 is tangentially connected to the upper part of the guide part 13, and the solid-liquid mixture flows along the guide part 13 and moves smoothly from the upper part of the guide part 13 to the junction of the cylinder surface 15, wherein the phase connection point between the cylinder surface 15 and the guide part 13 is the second phase connection point 151, and the solid-liquid mixture makes a second turn in the second phase connection point 151, so that the solid-liquid mixture can flow back to the middle part of the cylinder 1 to form a circulation.

[0050] See also Figure 3 In the embodiment of the present invention, the number of the second phase connecting wires 151 is two and they are symmetrically inclined and bent from the top of the cylinder 1 to the two sides of the guide portion 13. The two second phase connecting wires 151 are provided to guide the movement of the solid-liquid mixture from the symmetrical two sides of the guide portion 13. At the same time, the inclined and bent arrangement can reduce the space for the solid-liquid mixture with smaller ice crystal particles such as ice cream to be retained in the guide portion 13, thereby improving the smoothness of the reflux of the solid-liquid mixture.

[0051] Furthermore, one end of the two second phase connections 151 intersects with each other, and the other ends bend and extend toward both sides of the guide portion 13 and are respectively connected to the two ends of the first phase connection 141. Along the reflux direction of the solid-liquid mixture, the two second phase connections 151 converge and intersect from both ends of the first phase connection 141 toward the upper part of the cylinder 1, so that when the solid-liquid mixture moves in the guide portion 13, it can be concentrated to the center of the upper part of the cylinder 1 to form a more concentrated reflux route, so that the overall cross-section of the refluxed solid-liquid mixture is smaller, and under the condition of a constant flow rate, the reflux flow rate of the solid-liquid mixture is improved, the reflux speed can be accelerated, and the solid-liquid mixture in a stirred state can be smoothly moved to the side end surface 14, ensuring the reflux efficiency and stirring effect.

[0052] See also Figure 2 and Figure 3 The barrel 1 also includes a feeding portion 11, which is arranged at one end of the barrel 1 away from the discharging assembly and located at the upper part of the barrel 1, so that the raw materials can be fully frozen and stirred after entering, wherein the feeding port 111 is arranged on the feeding portion 11, and the cross-section of the feeding port 111 gradually decreases from top to bottom. The larger feeding port 111 is convenient for pouring raw materials, and the feeding port 111 after shrinking is also convenient for concentrating raw materials.

[0053] The stirring member 42 is spiral-shaped and can stir the solid-liquid mixture by rotating. It is a direct driving component for the movement of the solid-liquid mixture. The end of the stirring member 42 close to the discharge assembly is provided with an extrusion end 421. The extrusion end 421 is the part of the stirring member 42 closest to the discharge assembly. In the extrusion end 421, the stirring member 42 will separate from the solid-liquid mixture. At this time, the driving force driving the solid-liquid mixture is converted into the subsequent extrusion force of the solid-liquid mixture forward. Figure 5, the minimum distance H1 between the extrusion end 421 and the side end face 14 is between 3mm-10mm. Exemplarily, the minimum distance H1 between the extrusion end 421 and the side end face 14 includes 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm or 10mm, but is not limited thereto. When the minimum distance between the extrusion end 421 and the side end face 14 is less than 3mm, the solid-liquid mixture is difficult to obtain sufficient reflux space due to the insufficient distance between the extrusion end 421 and the side end face 14, which affects the reflux effect. When the minimum distance between the extrusion end 421 and the side end face 14 is greater than 10mm, the solid-liquid mixture refluxes slowly due to the excessive distance between the extrusion end 421 and the side end face 14, and the volume of the cylinder 1 is also increased.

[0054] See also Figure 6The spiral portion of the stirring member 42 is a portion for stirring the solid-liquid mixture, and is spiral in shape as a whole, and can stir and push the solid-liquid mixture by rotating. In some embodiments, the maximum distance H2 between the outer edge of the spiral portion of the stirring member 42 and the inner wall of the upper portion of the cylinder 1 ranges from 2 mm to 38 mm. Specifically, the maximum distance H2 between the outer edge of the spiral portion of the stirring member 3 and the inner wall of the upper portion of the cylinder 1 includes 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, 10.5mm, 11mm, 11.5mm, 12mm, 12.5mm, 13mm, 13.5mm, 14mm, 14.5mm, 15mm, 15.5mm, 16mm, 16.5mm, 17mm, 17.5mm, 18mm, 18.5mm, 19mm , 19.5mm, 20mm, 20.5mm, 21mm, 21.5mm, 22mm, 22.5mm, 23mm, 23.5mm, 24mm, 24.5mm, 25mm, 25.5mm, 26mm, 26.5mm, 27mm, 27.5mm, 28mm, 28.5mm, 29mm, 29.5mm, 30mm, 30.5mm, 31mm, 31.5mm, 32mm, 32.5mm, 33mm, 33.5mm, 34mm, 34.5mm, 35mm, 35.5mm, 36mm, 36.5mm, 37mm, or 37.5mm, but is not limited to these. When the maximum distance between the outer edge of the spiral portion of the stirring member 42 and the inner wall of the upper part of the cylinder 1 is less than 2 mm, the volume is small, and the outer edge of the spiral portion of the stirring member 42 and the inner wall of the upper part of the cylinder 1 need to maintain a certain distance to retain as much accommodation space as possible and leave space for the reflux of the solid-liquid mixture. When the maximum distance between the outer edge of the spiral portion of the stirring member 42 and the inner wall of the upper part of the cylinder 1 is greater than 38 mm, the volume is too large, the stirring member 42 cannot thoroughly stir the solid-liquid mixture, and it is easy to cause problems such as material accumulation and retention.

[0055] In some embodiments, the maximum distance H3 between the outer edge of the spiral portion of the stirring member 42 and the inner wall of the lower portion of the cylinder 1 ranges from 1.5 mm to 4 mm. Exemplarily, the maximum distance H3 between the outer edge of the spiral portion of the stirring member 3 and the inner wall of the lower portion of the cylinder 1 includes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm or 4 mm, but is not limited thereto. The outer edge of the spiral portion of the stirring member 42 is close to the inner wall of the lower portion of the cylinder 1. Due to the gravity effect, the lower portion of the cylinder 1 is prone to retaining a solid-liquid mixture. Therefore, it is necessary to minimize the distance between the inner wall of the cylinder 1 and the outer edge of the spiral portion of the stirring member 42, so that the stirring member 42 can scrape off the solid-liquid mixture on the inner wall of the lower portion of the cylinder 1 as much as possible to prevent material retention. When the maximum distance between the outer edge of the spiral portion of the stirring member 42 and the inner wall of the lower portion of the cylinder 1 is greater than 4 mm, the stirring member 42 cannot thoroughly stir the solid-liquid mixture in the lower portion of the cylinder 1; and when the maximum distance between the outer edge of the spiral portion of the stirring member 42 and the inner wall of the lower portion of the cylinder 1 is less than 1.5 mm, the distance between the stirring member 42 and the inner wall of the cylinder 1 is too small, which affects the movement of the solid-liquid mixture and hinders the rotation of the stirring member 42.

[0056] In some embodiments, the maximum distance H4 between the outer edge of the spiral portion of the stirring member 42 and the inner walls on the left and right sides of the cylinder 1 ranges from 1.5 mm to 6 mm. Exemplarily, the maximum distance H4 between the outer edge of the spiral portion of the stirring member 3 and the inner walls on the left and right sides of the cylinder 1 includes 1.5 mm, 2 mm, 2.5 mm, 3 mm, 3.5 mm, 4 mm, 5 mm, 5.5 mm or 6 mm, but is not limited thereto. Since the solid-liquid mixture on the left and right sides of the cylinder 1 will move downward under the action of gravity, the distance between the outer edge of the spiral portion of the stirring member 42 and the inner walls on the left and right sides of the cylinder 1 can be kept applicable to accommodate more solid-liquid mixture. When the maximum distance between the outer edge of the spiral portion of the stirring member 42 and the inner walls on the left and right sides of the cylinder 1 is less than 1.5 mm, the distance between the stirring member 42 and the inner wall of the cylinder 1 is too small, which will affect the movement of the solid-liquid mixture and hinder the rotation of the stirring member 42; when the maximum distance between the outer edge of the spiral portion of the stirring member 42 and the inner walls on the left and right sides of the cylinder 1 is greater than 6 mm, the volume is too large, the stirring member 42 cannot thoroughly stir the solid-liquid mixture, and is prone to problems such as material accumulation and retention.

[0057] In addition, the barrel 1 also includes a transition connection portion 16, which protrudes upward from the surface of the barrel surface 15, and the feed portion 11 is arranged on the transition connection portion 16. Since the transition connection portion 16 protrudes upward, the position of the feed portion 11 is improved, which makes it easier to pour in raw materials, and also expands the space for accommodating raw materials. A feed cavity 161 is arranged in the transition connection portion 16, and the feed cavity 161 is connected to the storage space 12. When pouring raw materials, the raw materials first enter the feed cavity 161 and then enter the storage space 12, wherein the diameter of the longitudinal section of the feed cavity 161 is greater than the maximum diameter of the longitudinal section of the storage space 12, so that the volume of raw materials and solid-liquid mixture that can be accommodated by the barrel 1 is increased.

[0058] See also Figure 4 The stirring member 42 includes a connecting ring 422, a transmission block 423 and a stirring bar 424. The connecting ring 422 is arranged at one end of the stirring member 42 close to the stirring drive member 41, and is used to fix the stirring bar 424. The transmission block 423 is arranged at one end of the stirring member 42 close to the discharging mechanism 2. The stirring bar 424 extends from the connecting ring 422 to the transmission block 423 in a spiral shape in the circumferential direction. The number of the stirring bars 424 is at least 2, and the two stirring bars 424 surround each other to form a multi-circle spiral. The stirring bars 424 can stir the solid-liquid mixture in the storage space 12, and push the solid-liquid mixture during rotation, so that the solid-liquid mixture is concentrated at the end where the discharging mechanism 2 is located, which is convenient for discharging. The movable end of the stirring drive member 41 passes through the connecting ring 422 and is connected to the transmission block 423 in a transmission manner.

[0059] The conventional stirring bar 424 is a simple spiral structure. In order to smoothly slide and rotate on the outer wall of the evaporator 31, a certain gap is provided between the stirring bar 424 and the evaporator 31. However, the existence of such a gap will cause the solid-liquid mixture on the surface of the evaporator 31 to be unable to be stirred, and then freeze on the surface of the evaporator 31. This situation not only fails to stir the solid-liquid mixture thoroughly, but also reduces the heat exchange capacity of the surface of the evaporator 31. In order to solve the above problems, in the embodiment of the present invention, a plurality of evenly distributed protrusions 425 are provided on the inner side of the stirring bar 424. The protrusions 425 protrude from the inner side of the stirring bar 424 and can abut against the surface of the evaporator 31. During the rotation of the stirring bar 424, the protrusions 425 can slide over the surface of the evaporator 31 to destroy the ice structure formed on the surface of the evaporator 31, so that the ice on the surface falls and is stirred along with the solid-liquid mixture. In this way, the solid-liquid mixture is thoroughly stirred and the heat exchange capacity of the surface of the evaporator 31 is guaranteed. Furthermore, the surface of the protrusion 425 is an outwardly convex arc surface, which can reduce the contact area between the protrusion 425 and the surface of the evaporator 31. On the one hand, it reduces the friction between the stirring bar 424 and the surface of the evaporator 31, and on the other hand, it can increase the pressure of the protrusion 425 on the ice on the surface of the evaporator 31, causing the ice to break.

[0060] See also Figure 1 and Figure 7 In order to fix the inlet and outlet assembly 10 and the evaporator 31, the shell assembly 5 also includes an upper support frame 52 and a sealing plate 53. The upper support frame 52 is provided with a receiving groove 521, and the notch of the receiving groove 521 faces upward. The sealing plate 53 is fixed in the receiving groove 521. The sealing plate 53 is vertically arranged, and the evaporator 31 is horizontally fixed in the sealing plate 53. The sealing plate 53 can be fixed to one end of the barrel 1 to form a seal for the barrel 1. After the barrel 1 is inserted into the periphery of the evaporator 31, the sealing plate 53 can form a sealing structure for the barrel 1, and at least a portion of the barrel 1 can be fixed in the receiving groove 521 after insertion.

[0061] In addition, a fixing groove 522 is provided at the lower part of the upper support frame 52, and the fixing groove 522 protrudes downward from the bottom surface of the upper support frame 52, and the stirring driving member 41 is fixed in the fixing groove 522. By arranging the stirring driving member 41 at the lower part of the upper support frame 52, the space at the rear side of the upper support frame 52 is saved to reduce the overall volume of the cold drink device, and the redundant space in the housing assembly 5 is utilized to improve the space utilization rate.
