Abstract
Description
Technical Field
[0001] This utility model relates to the field of slush technology, and in particular to a rotating scraper structure for a slush machine. Background Technology
[0002] A slush machine, also known as a slush machine, snow slush machine, snow slush juice machine, or slush juice machine, is what we commonly call a freezing machine. It is used to process cold desserts, slushies, snow slushies, and other cold drinks. These drinks are suitable for all ages and are an excellent choice for cooling down in the hot summer.
[0003] In existing slush machines, the raw liquid condenses on the surface of the evaporator and is then scraped off by a scraper. However, due to the limitations of the scraper's structure, the slush on the evaporator surface cannot be completely scraped off, and it tends to accumulate on the scraper after being scraped off, causing solidified ice blocks to form on the scraper surface. This affects the subsequent scraping of ice layers and leaves residue on the evaporator surface, resulting in low ice dispensing efficiency. Utility Model Content
[0004] In order to solve the above-mentioned problems in the prior art, the present invention provides a rotating scraper structure for a slush machine.
[0005] The above-mentioned problems of this utility model are solved by the following technical solution:
[0006] A rotating scraper structure for a slush machine includes a blade holder fitted onto the outside of the evaporator of the slush machine. At least three straight blades are formed on the blade holder along the axial direction of the evaporator, and a spiral blade is connected between adjacent straight blades.
[0007] The spiral cutter and the straight cutter are joined at the head to form an outlet blade;
[0008] The straight blade is equipped with an ice-scraping blade.
[0009] A further feature of the above technical solution is that the ice-scraping blade is located on the straight blade near the evaporator, and the blade thickness increases outward along the evaporator axis.
[0010] A further feature of the above technical solution is that the side of the ice scraper blade furthest from the evaporator is the blade surface, and the blade surface is inclined outward along the radial direction of the evaporator.
[0011] A further setting of the above technical solution is that the thickness growth direction of the blade surface is consistent with the rotation direction of the evaporator.
[0012] By adopting the above technical solution, the blade surface of the ice scraper is inclined outward along the radial direction of the evaporator, and the direction of thickness increase is consistent with the rotation direction of the evaporator. At the moment the ice is scraped, due to the speed difference between the ice layer and the blade edge, the ice will move away from the evaporator along the blade surface, avoiding accumulation and condensation in the same position, thus improving the smoothness of the discharge.
[0013] A further setting of the above technical solution is that the inclination angle of the ice scraper blade is in the range of 20° < a < 35°.
[0014] By adopting the above technical solution and rationally selecting the blade angle of the ice scraper, it is possible to avoid both excessively large angles that lead to insufficient radial movement speed of ice and difficulty in accumulating and discharging, and excessively small angles that lead to thin ice scrapers that are prone to breakage, thus balancing ice scraping efficiency and structural strength.
[0015] A further provision of the above technical solution is that the head of the outlet blade is provided with an outlet surface parallel to the cross-section of the evaporator.
[0016] By adopting the above technical solution, the head of the outgoing blade is set with an outgoing surface parallel to the cross-section of the evaporator. The ice shavings fall vertically along the outgoing surface and can accurately enter the discharge port. The outgoing blades and the spiral blades are in the same spiral direction, forming a continuous guide surface, making the transition of ice shavings from the spiral blades to the outgoing blades smoother. The straight blades hold the guide surface of the outgoing blades, which enhances the structural stability of the outgoing blades and avoids shaking caused by the weight of the ice shavings.
[0017] A further feature of the above technical solution is that the outgoing blade is also spirally arranged, and the rotation direction follows the spiral blade.
[0018] A further setting of the above technical solution is: the straight blade is held against the guide surface of the outgoing blade.
[0019] A further provision of the above technical solution is that three straight blades, three spiral blades, and three guide vanes are provided.
[0020] A further setting of the above technical solution is that the rear end of the outgoing blade (400) is close to the front end face of the evaporator.
[0021] Compared with the prior art, the beneficial effects of this utility model are as follows: an ice-scraping blade is set on the straight blade, and through the special structure of the ice-scraping blade, the thin ice layer on the surface of the evaporator can be scraped efficiently, which effectively solves the problems of low ice scraping efficiency and ice residue in traditional slush machines; at the same time, the transition between the ice-scraping blade and the straight blade body is natural, ensuring the connection strength of the ice-scraping blade and making it less prone to breakage.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0033] like Figure 1-5 As shown in the figure, this embodiment discloses a rotating scraper structure for a slush machine.
[0034] A rotating scraper structure for a slush machine includes a blade holder 100 sleeved to the outside of the evaporator of the slush machine. At least three straight blades 200 are formed on the blade holder 100 along the axial direction of the evaporator, and a spiral blade 300 is connected between adjacent straight blades 200.
[0035] The spiral cutter 300 and the straight cutter 200 are joined at the head to form an outlet blade 400;
[0036] The straight blade 200 is equipped with an ice-scraping blade 210.
[0037] The above is the basic scheme of this embodiment.
[0038] Specific reference Figure 1 As shown, the tool holder 100 is an annular sheet body. A straight blade 200 is formed on one end face of the tool holder 100. A spiral blade 300 is formed between two adjacent straight blades 200. The front end of the spiral blade 300 extends into an outlet blade 400. The heads of multiple outlet blades 400 are connected to each other and simultaneously connected to the heads of the straight blades 200 to form a complete outlet head.
[0039] When the scraper is installed on the slush machine, it is fitted onto the outside of the evaporator. The blade holder 100 is located at the tail of the evaporator, so that the straight blade 200 is arranged axially on the outer surface of the evaporator and is infinitely close to the outer surface of the evaporator. At the same time, the spiral blade 300 is spirally wrapped around the surface of the evaporator and is also infinitely close to the evaporator. When the evaporator rotates, the spiral blade 300 and the straight blade 200 remain stationary and rotate relative to the outer surface of the evaporator, thereby scraping off the ice layer that has condensed on the outer surface of the evaporator. After the ice layer is scraped off to form loose slush, it moves along the surface of the spiral blade 300, enters the position of the outlet blade 400, and falls into the ice outlet of the beverage container for slush output.
[0040] Reference Figure 2 As shown, in this embodiment, the straight blade 200 is provided with an ice-scraping blade 210. The ice-scraping blade 210 is located near the evaporator and contacts the ice layer on the surface of the evaporator to scrape off the ice layer. Compared with the straight blade 200 in the prior art, the ice-scraping blade 210 increases the friction between the end face of the straight blade 200 and the ice layer, thereby enabling more effective scraping of the ice layer.
[0041] Preferably, in this embodiment, three straight blades 200, three spiral blades 300, and three guide blades 400 are provided.
[0042] Preferably, in this embodiment, the ice scraping blade 210 is disposed on the straight blade 200 near the evaporator side, and the blade thickness increases sequentially outward along the evaporator axis.
[0043] In other words, the blade thickness is smallest on the side closer to the evaporator, resulting in a very small contact area with the ice layer on the evaporator surface. This leads to a large frictional force between the blade and the ice layer during relative rotation, effectively scraping off the ice. On the side farther from the evaporator, the blade thickness is larger. In this embodiment, it is preferably the same as the thickness of the straight blade 200 body, thus transitioning to the straight blade 200 body and ensuring the consistency of the straight blade 200's shape and the connection strength of the ice-scraping blade 210 on the straight blade 200, making it less prone to breakage.
[0044] In this embodiment, the ice scraping blade 210 is specifically configured as follows: one end face of the ice scraping blade 210 is close to the evaporator and is set in an arc shape along the surface of the evaporator, and the other end face is set as the blade surface 211. The blade surface 211 is set to be radially outward along the evaporator. That is to say, the blade thickness is consistent on any straight line parallel to the axis of the evaporator on the blade surface 211, so that the ice scraping blade 210 scrapes the surface of the evaporator in a circumferential direction.
[0045] At the same time, refer to Figure 3 and Figure 4As shown, in this application, the side away from the evaporator is set as the blade surface 211. The ice sand formed after the ice layer is scraped off moves along the ice scraping blade 210 in the direction away from the evaporator, guiding the ice sand to ensure that the ice sand is completely separated from the evaporator and to prevent the ice sand from adhering to the evaporator again.
[0046] In this embodiment, the thickness growth direction of the cutting edge 211 is consistent with the rotation direction of the evaporator.
[0047] As shown in the figure, the side of the blade 211 closest to the evaporator is set as a blade edge, which is connected to the other side of the blade 211 and the ice scraping blade 210. The ice scraping blade 210 forms a blade angle at the blade edge, and the expansion direction of the blade angle is consistent with the rotation direction of the evaporator cylinder.
[0048] When the evaporator rotates under the action of the driving component, the ice layer condensed on the evaporator also rotates synchronously, with the same rotational speed as the surface of the evaporator, while creating a speed difference with the cutting edge. When the cutting edge scrapes the ice layer into ice shavings, the ice shavings still have the same speed as the evaporator. Therefore, the formed ice shavings move along the inclined plane, moving towards the surface away from the evaporator.
[0049] Compared to other blade surfaces 211, the blade surface 211 in this embodiment can adapt to the speed direction at the moment of scraping ice sand, and decompose the speed of ice sand as it moves along the blade surface 211, so that the ice sand moves along the inclined surface, avoiding the accumulation of ice sand in the same position and forming a thick block of ice that would cause difficulties in discharging.
[0050] Preferably, in this embodiment, the inclination angle of the blade surface 211 of the ice scraping blade 210 is in the range of 20° < a < 35°.
[0051] Preferably, in this embodiment, the inclination angle of the cutting edge 211 is 25°.
[0052] If the inclination angle of the blade 211 is too large, it will reduce the radial movement speed of the ice and sand, causing the ice and sand to accumulate on the blade 211 and making it difficult to discharge. If the inclination angle of the blade 211 is too small, the ice scraping blade 210 will be too thin, with low strength, and will be easy to break.
[0053] In actual slush machines, the discharge port is usually located below the beverage container. Therefore, the slush needs to fall vertically from the discharge blade 400. In this embodiment, the head of the discharge blade 400 is provided with a discharge surface 410 that is parallel to the cross-section of the evaporator.
[0054] Reference Figure 5As shown, the outlet surface 410 is parallel to the radial section of the evaporator. That is, the outlet surface 410 near the discharge port is vertically downward. When the ice slush moves along the outlet blade 400 to the outlet surface 410, it falls vertically downward along the outlet surface 410, thus accurately falling into the discharge port.
[0055] The outlet surfaces 410 on the other outlet blades 400 are inclined, and the slush falls along the inclined outlet surfaces 410 onto the outlet blades 400 or outlet surfaces 410 below.
[0056] In this embodiment, the outgoing blade 400 is also spirally arranged, and the rotation direction follows the spiral blade 300.
[0057] The export blade 400 and the spiral blade 300 are integrated, and the spiral angles of the export blade 400 and the spiral blade 300 are consistent, so that a consistent guide surface is formed between the spiral blade 300 and the export blade 400, and the ice shavings scraped by the spiral blade 300 can move smoothly to the part of the export blade 400.
[0058] Furthermore, the spiral structure of the outgoing blade 400 gives it a guide surface facing the straight blade 200, which rests against the guide surface of the outgoing blade 400.
[0059] The blades of the export blade 400 are relatively large and thin. Therefore, when carrying a large amount of slush, the stability of the export blade 400 is not high and it is prone to shaking. The straight blade 200 supports the export blade 400, increasing its strength and thus ensuring the stability of the rotating scraper during the slush export process.
[0060] In addition, in this embodiment, the rear end of the outgoing blade 400 is close to the front end face of the evaporator.
[0061] The rear end of the 400-degree blade approaches the front end of the evaporator, scrapes off the ice layer condensed on the front end of the evaporator, and then outputs it along the guide surface.
[0062] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
