Description

Technical Field

[0001] The utility model relates to the technical field of snow melting machines, in particular to an evaporation device and a refrigeration system for a snow melting machine. Background Art

[0002] As a widely used beverage preparation device, the core function of a snow melting machine is to make ice sand from liquid substances such as fruit juice and dairy products. In this process, the evaporation cooling component and the stirring component play key roles. The evaporation cooling component reduces the temperature of the mixing chamber through the refrigerant cycle, and the stirring component stirs the ice crystal mixture that has cooled and frozen into ice sand. In traditional snow melting machines, the evaporation cooling component and the stirring component need to be connected together to facilitate the stirring of the ice crystal mixture. There is a driving motor in the stirring component. To prevent potential safety hazards, it is necessary to isolate the mixing chamber from the driving motor and set up a sealing mechanism for waterproofing. The sealing mechanism of the stirring component in existing snow melting machines is usually an ordinary gasket, which is arranged between the motor protection shell and the mixing chamber. However, since the ordinary gasket has a flat structure, the sealing effect is relatively average. Moreover, the driving motor is a moving component. During use, the vibration generated by the driving motor may cause the gasket to shift, etc., further reducing the waterproof performance and causing potential safety hazards.

[0023] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0024] See also Figure 1 and Figure 2 The present invention discloses an evaporation device for a snow melter, comprising an evaporation mechanism 2, an outer cover 1 disposed around the evaporation mechanism 2, and a rotary stirring mechanism 3 disposed at one end of the evaporation mechanism 2. The outer cover 1 is used to contain liquid, which is cooled and frozen by the evaporation mechanism 2 within the outer cover 1. The stirring mechanism then stirs the frozen ice crystal mixture to promote uniform freezing of the liquid and prevent the ice crystal mixture from forming ice cubes. The evaporation mechanism 2 includes a cooling cylinder 21 and an evaporator 22 disposed within the cooling cylinder 21. The refrigerant evaporates and absorbs heat within the evaporator 22, and the liquid exchanges heat through the cooling cylinder 21, causing the ice crystal mixture to freeze on the surface of the cooling cylinder 21. The rotary stirring mechanism 3 includes a protective shell 31, a drive member 32 disposed within the protective shell 31, and a scraper 33 drivingly connected to the drive member 32. The scraper 33 is disposed around the evaporator 22 and within the outer cover 1. During freezing, the drive member 32 drives the scraper 33 to rotate in a circular motion around the cooling cylinder 21 to drive the ice crystal mixture to flow on the surface of the cooling cylinder 21, thereby preventing ice crystals from gathering at the lower part of the outer cover 1, improving the uniformity of freezing, and preventing the ice crystal mixture from forming larger ice cubes.

[0025] Wherein the protective case 31 is used to protect the driving member 32. The protective case 31 is provided on the side of the outer cover 1. The cooling cylinder 21 is connected to the protective case 31. During use, it is necessary to prevent the liquid outside the cooling cylinder 21 from entering the protective case 31. To improve the sealing performance and waterproof performance, the evaporation device for the snow melting machine further includes a sealing ring 4. The sealing ring 4 has elasticity and can achieve a good sealing effect. One end of the cooling cylinder 21 is provided with a fixing ring 23. The fixing ring 23 is connected to the protective case 31. The sealing ring 4 is arranged between the fixing ring 23 and the protective case 31 and is used to form a barrier and waterproof function between the cooling cylinder 21 and the protective case 31. The sealing ring 4 includes a sealing inner ring 41 and an inner sealing portion 42. The sealing inner ring 41 is arranged on the inner ring of the sealing ring 4. The inner sealing portion 42 is arranged on the side of the sealing ring 4 close to the protective case 31. The sealing inner ring 41 abuts against the edge of the protective case 31, and the inner sealing portion 42 abuts against the fixing ring 23. Therefore, it can conduct sealing and waterproofing from two parts, which not only improves the waterproof and sealing performance but also increases the fixed position, forms fixation in two directions, and makes the connection firm.

[0026] The beneficial effects of the embodiments of the present utility model are as follows:

[0027] The evaporation device for the snow melting machine in the embodiments of the present utility model is provided with an evaporation mechanism 2, an outer cover 1, a stirring mechanism, and a sealing ring 4. The evaporation mechanism includes a cooling cylinder 21 and an evaporator 22. The evaporator 22 evaporates the refrigerant to cool the liquid by the cooling cylinder 21. The rotary stirring mechanism 3 includes a protective case 31, a driving member 32, and a scraper �. When the liquid freezes to form an ice crystal mixture, the driving member 32 drives the scraper 33 to stir the ice crystal mixture to form ice sand. One end of the cooling cylinder 21 is provided with a fixing ring 23. To achieve good sealing and waterproofing, the sealing ring 4 has elasticity. The sealing ring 4 includes a sealing inner ring 41 and an inner sealing portion 42. The sealing inner ring 41 abuts against the edge of the protective case 31, and the inner sealing portion 42 abuts against the fixing ring 23. By providing the sealing inner ring 41 and the inner sealing portion 42, it is possible to conduct sealing and waterproofing from the inner ring part and the part close to the inner side of the protective case 31, thereby achieving a good sealing and waterproofing effect. Moreover, by fixing from the inner ring part and the part close to the inner side of the protective case 31 in two directions, it can play a good fixing role, make the connection firm, and avoid deviation from affecting the waterproofing effect.

[0028] Specifically, refer to Figure 3, the fixing ring 23 is arranged at the edge of the cooling cylinder 21 on the side close to the protective shell 31. The fixing ring 23 extends outward from the cooling cylinder 21 to form a flange shape. The fixing ring 23 is provided with fixing holes 231. The end of the protective shell 31 is provided with an inner ring part 34. An inner fixing plate 341 is arranged on the side of the inner ring part 34 away from the outer cover 1. The cooling cylinder 21 is fixed on the inner fixing plate 341 through the fixing holes 231. During installation, the cooling cylinder 21 passes through the inner ring part 34, the inner fixing plate 341 limits the fixing ring 23, and then fasteners such as screws are used to fix the fixing holes 231, so that the cooling cylinder 21 and the protective shell 31 can be connected.

[0029] Among them, the inner sealing part 42 is arranged at the edge of the sealing inner ring 41 on the side close to the protective shell 31. The inner sealing part 42 extends outward from the edge of the sealing inner ring 41 to the outside of the sealing inner ring 41. The inner sealing part 42 is arranged between the fixing ring 23 and the inner fixing plate 341. During installation, the sealing ring 4 is fixed in the inner ring part 34 so that the inner sealing part 42 abuts against the inner fixing plate 341. Then, the cooling cylinder 21 passes through the sealing inner ring 41 and the inner ring part 34 in sequence from the other side, and the fixing ring 23 can abut against the inner fixing plate 341.

[0030] See Figure 2 , in order to enable the cooling cylinder 21 to pass through the inner ring part 34, the inner ring part 34 is provided with an installation hole 342. The sealing inner ring 41 is arranged in the installation hole 342. The sealing inner ring 41 can be snapped into the installation hole 342. After installation, the outer wall of the sealing inner ring 41 abuts against the inner wall of the installation hole 342. Then, the cooling cylinder 21 passes through the sealing inner ring 41, and the outer wall of the cooling cylinder 21 abuts against the inner wall of the sealing inner ring 41. Therefore, the sealing ring 4 not only forms sealing and fixing in the vertical direction by relying on the inner sealing part 42 and the fixing ring 23, but also forms sealing and fixing in the horizontal direction by relying on the installation hole 342 and the sealing inner ring 41.

[0031] Further, the inner wall of the sealing inner ring 41 is provided with a rib 411. The outer edge of the rib 411 is arranged on the inner wall of the sealing inner ring 41. The inner edge of the rib 411 extends inwards obliquely towards the side away from the driving member 32. The inclined direction of the rib 411 is the same as the insertion direction of the cooling cylinder 21, so it will not hinder the installation of the cooling cylinder 21. In addition, there is a gap between the side wall of the rib 411 and the inner wall of the sealing inner ring 41. This gap can provide buffering during installation, and the rib 411 can abut against the outer wall of the cooling cylinder 21 to form a seal. In the embodiment of the present invention, the number of the ribs 411 is 2, and multiple ribs can also be provided to further enhance the seal.

[0032] Further, referring to Figures 3 - 5 , the sealing ring 4 further includes an outer sealing portion 43 and a front end face 44. The outer sealing portion 43, the front end face 44 and the inner sealing ring 4 enclose a sealing cavity 45. An outer convex ring 343 is provided in the inner ring portion 34. The outer convex ring 343 protrudes towards the side away from the inner fixing plate 341. The outer convex ring 343 is arranged in the sealing cavity 45. The outer sealing portion 43 and the front end face 44 form a waterproof seal for the protective shell 31 from the side opposite to the inner sealing portion 42. The outer convex ring 343 plays a limiting role on the sealing cavity 45.

[0033] The front end face 44 is arranged on the side of the sealing inner ring 41 away from the inner sealing portion 42. The inner edge of the front end face 44 is connected to the sealing inner ring 41. The outer edge of the front end face 44 is connected to the outer sealing portion 43. The outer sealing portion 43 extends outwards obliquely from the outer edge of the front end face 44 towards the side away from the cooling cylinder 21. The outer sealing portion 43 can block the liquid outside the sealing inner ring 41, thereby further improving the waterproof sealing performance.

[0034] Referring to Figure 5 , the inner ring portion 34 further includes an upper convex plate 344, which protrudes towards the side away from the inner fixing plate 341. There is a gap between the upper convex plate 344 and the outer convex ring 343. The upper convex plate 344 and the outer convex ring 343 enclose a fixing groove 345. The outer sealing portion 43 can be inserted into the fixing groove 345. The fixing groove 345 can form a limit on the outer sealing portion 43. Moreover, a plurality of connecting holes 346 are provided in the fixing groove 345. A plurality of connecting heads 431 are provided on the side of the outer sealing portion 43 close to the inner ring portion 34. When installing the sealing ring 4, the connecting heads 431 can be inserted into the connecting holes 346, so as to form a very firm connection and avoid offset affecting the waterproof effect.

[0035] Referring to Figure 6, wherein the connector 431 includes a first boss end 4311 and a second boss end 4312, the first boss end 4311 and the second boss end 4312 are integrally arranged, and the first boss end 4311 and the second boss end 4312 can be inserted into the connection hole 346. After being inserted into the connection hole 346, the second boss end 4312 and the first boss end 4311 extend out of the connection hole 346 in sequence. Wherein the first boss end 4311 abuts against the connection hole 346. Since the cross-sectional width of the connection hole 346 is smaller than the cross-sectional width of the first boss end 4311 and larger than the cross-sectional width of the second boss end 4312, the second boss end 4312 and the first boss end 4311 can be inserted into the connection hole 346 in sequence. After being inserted, the first boss end 4311 can abut against the inside of the connection hole 346 and will not come out of the connection hole 346, thus forming a tight connection effect. And setting the cross-sectional width of the connection hole 346 to be smaller than the cross-sectional width of the first boss end 4311 and larger than the cross-sectional width of the second boss end 4312 can enable the second boss end 4312 to be smoothly inserted into the connection hole 346, and then drive the first boss end 4311 to be inserted into the connection hole 346, so as to facilitate the connector 431 to pass through the connection hole 346 more smoothly.

[0036] The embodiment of the present invention also discloses a refrigeration system (not shown in the drawings), which includes the evaporation device for a snow melting machine as described above. The sealing ring 4 is made of rubber material or silica gel material. The sealing ring 4 made of rubber material has good elasticity and deformability, can adapt to sealing surfaces of different shapes and materials, effectively fill tiny leakage gaps, and achieve excellent sealing and waterproof effects. The evaporation device for the snow melting machine is between the protective shell 31 and the cooling cylinder 21. Wherein the sealing ring 4 includes a sealing inner ring 41 and an inner sealing portion 42. The sealing inner ring 41 abuts against the edge of the protective shell 31, and the inner sealing portion 42 abuts against the fixing ring 23. Therefore, it can seal from the vertical direction and the horizontal direction respectively to achieve a better waterproof effect. Moreover, being fixed from two directions of the inner ring portion 34 and the portion close to the inside of the protective shell 31 can play a better fixing role and can avoid offset and affect the waterproof effect. The refrigeration system is an ice cream maker or a snow melting machine or a smoothie maker, and can make ice cream, ice cream cones or smoothies, etc.

[0037] The above are the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches can still be made, and these improvements and retouches are also regarded as the protection scope of the present invention.
