Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a small vertical snow melting machine. Background Technology

[0002] Currently, most snow melting machines are horizontal in structure, meaning the stirring motor is placed horizontally. The resulting slush is propelled horizontally by the stirring blades driven by the motor, and then discharged through a discharge device. This type of horizontal snow melting machine typically has the disadvantage of being relatively large. To reduce the size of snow melting machines, a vertical structure with the motor placed vertically is generally adopted. However, the internal structure layout of ordinary vertical snow melting machines is not rational enough, and the internal space of the casing is not fully utilized, resulting in the problem of the overall machine being too large. This is not conducive to the miniaturization of electrical products, and for consumers, it leads to a poor experience in terms of product aesthetics and carrying and transporting the appliance.

[0003] In addition, the ice slush container of a regular vertical snow melting machine is not detachable. The ice slush is discharged through a discharge device located on one side of the bottom of the ice slush container. The direction of ice slush production and discharge is inconsistent, which can easily cause the accumulated ice slush to be squeezed. After being squeezed, it will quickly form ice blocks, eventually causing ice blockage at the discharge port. Utility Model Content

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] Reference Figure 1and Figure 2 This utility model discloses a small vertical snow melting machine, comprising: a housing 100 extending vertically, a horizontally extending flat cantilever 200 at the top of the housing 100, a downwardly extending refrigeration evaporator 300 and an ice scraping mechanism 400, the ice scraping mechanism 400 including a vertically rotatable shaft 410 mounted on the cantilever 200, the lower end of the shaft 410 being connected to a scraper 420 cooperating with the refrigeration evaporator 300, a motor 430 being provided in the upper part of the housing 100, and a transmission assembly 440 connecting the upper end of the shaft 410 to the motor 430 inside the cantilever 200.

[0030] The vertical snow melting machine with the above structure has a refrigeration evaporator 300 and an ice scraping mechanism 400 arranged below the cantilever section 200. The transmission component 440 is housed in the internal space of the cantilever section 200, and the motor 430 connected to the transmission component 440 is arranged in the upper part of the housing 100. This helps to limit the height of the cantilever section 200 to a smaller value and also helps to make full use of the internal space of the housing 100. The vertical snow melting machine has a compact structure and reasonable layout, which is conducive to miniaturization, easy to carry and transport, and home use.

[0031] See Figure 2 In some embodiments of this utility model, a compressor 500 is provided at the bottom of the interior of the housing 100. The compressor 500 is sequentially connected to a condenser 600 and a throttling device located above it. The throttling device is connected to the compressor 500 via the evaporator 300. The motor 430 is located directly above the compressor 500. It should be understood that the compressor 500, condenser 600, throttling device, and evaporator 300 are sequentially connected to form an air conditioning refrigeration system. Compared to a refrigeration chip system, this system can provide more and more stable cooling capacity to the evaporator 300. Under this premise, with the compressor 500 located at the bottom of the housing 100 and the condenser 600, throttling device, and motor 430 located above it, it is beneficial to fully utilize the internal space of the housing 100 and reduce wasted volume.

[0032] See Figure 1 and Figure 2In some embodiments of this utility model, the condenser 600 is installed on a side wall of the housing 100 away from the evaporator 300. The housing 100 has an air outlet 110 facing the condenser 600 and an air inlet 120 connecting the inner cavity of the housing 100 and the air outlet 110. A receiving space 130 is defined between the side wall of the condenser 600 and the inner wall of the housing 100, located above the compressor 500. A portion of the motor 430 extends downward into the receiving space 130. When the fan of the condenser 600 is working, external gas enters the interior of the housing 100 through the air inlet 120, and then the gas passes through the heat exchanger section of the condenser 600 and is discharged from the air outlet 110. It should be noted that the thickness of the condenser 600 along the horizontal direction is smaller than the diameter of the compressor 500. Therefore, the area above the compressor 500 has the aforementioned accommodating space 130 on one side of the condenser 600. This accommodating space 130 can just accommodate at least part of the motor 430, further improving the utilization rate of the internal space of the housing 100 and facilitating the miniaturization of the vertical snow melting machine.

[0033] See Figure 2 In some embodiments of this utility model, the interior of the overhang 200 is provided with a transmission box 210, the output shaft of the motor 430 is rotatably connected to one end of the transmission box 210 vertically upward, the rotating shaft 410 is rotatably connected to the other end of the transmission box 210, the transmission assembly 440 includes a gear pair disposed in the transmission box 210 and connected between the output shaft of the motor 430 and the rotating shaft 410, or the transmission assembly 440 includes a pulley assembly disposed in the transmission box 210 and connected between the output shaft of the motor 430 and the rotating shaft 410. It is understandable that the length direction of the transmission box 210 is set along the extension direction of the overhang 200. When a gear pair is set between the output shaft of the motor 430 and the rotating shaft 410, the gear pair includes a driving gear on the output shaft of the motor 430, a driven gear on the rotating shaft 410, and multiple linkage gears meshing between the driving gear and the driven gear. According to the needs of use, different transmission ratios can be designed to achieve the effect of accelerating or decelerating rotation. When a pulley assembly is set between the output shaft of the motor 430 and the rotating shaft 410, the pulley assembly includes a driving pulley on the output shaft of the motor 430, a driven pulley on the rotating shaft 410, and a belt connecting the driving pulley and the driven pulley. Both of the above transmission methods are conducive to designing a smaller height dimension of the overhang 200.

[0034] See Figure 2In some embodiments of this utility model, the top of the housing 100 is provided with a horizontally extending first extension plate 220, and the transmission box 210 includes a bottom box 211 fixedly connected to the first extension plate 220 and a front box 212 detachably connected to the bottom box 211. A second extension plate 230 is detachably connected above the first extension plate 220, and a sandwich area for accommodating the transmission box 210 is defined between the first extension plate 220 and the second extension plate 230. When maintenance and adjustment of the transmission assembly 440 are required, the second extension plate 230 can be removed from the first extension plate 220, and then the front box 212 can be removed from the bottom box 211 for maintenance and adjustment of the transmission assembly 440.

[0035] See Figure 3 and Figure 4 In some embodiments of this utility model, the cantilever 200 is detachably connected to a slush container 700 that can be fitted onto the outside of the refrigeration evaporator 300 and the ice scraping mechanism 400. One of the slush container 700 and the cantilever 200 is provided with at least two rotating slots 810 that are circumferentially distributed around a certain vertical axis, and the other is provided with a buckle 820 that corresponds one-to-one with the rotating slots 810. When making slush, liquid is first poured into the slush container 700. The slush container 700 is then fitted onto the outside of the refrigeration evaporator 300 and the ice scraping mechanism 400 and moved upwards into place. Then, the slush container 700 is rotated so that the snap-fit ​​part 820 and the rotating slot 810 are engaged together. The liquid cools on the surface of the refrigeration evaporator 300 to form ice flakes. The ice scraping mechanism 400 scrapes off the ice flakes and breaks the ice to form slush. After the slush is made, the slush container 700 is rotated in the opposite direction so that the snap-fit ​​part 820 and the rotating slot 810 are disengaged, and the slush container 700 can be pulled downwards to transfer or pour the slush. This achieves a slush making method that is completely different from the existing technology. It avoids the need for valves at the slush outlet and the need to change the slush outlet channel from vertical to horizontal, thus avoiding the problem of clogging during slush dispensing. The slush container 700 is very easy to assemble and disassemble and is convenient to use.

[0036] See Figure 1 , Figure 3 and Figure 4In some embodiments of this utility model, the smoothie container 700 includes a cylindrical cup body 710, a handle 720 on the side of the cylindrical cup body 710, and a circular wall plate 240 at the lower end of the cantilever portion 200 that cooperates with the cylindrical cup body 710. A snap-fit ​​portion 820 is formed on the outer peripheral wall of the cylindrical cup body 710, and a rotating groove 810 is formed on the inner peripheral wall of the circular wall plate 240. It is understood that, compared to the case where the snap-fit ​​portion 820 or the rotating groove 810 is formed on the inner peripheral wall of the cylindrical cup body 710, forming the snap-fit ​​portion 820 on the outer peripheral wall of the cylindrical cup body 710 is beneficial for cleaning the smoothie container 700, preventing the melted liquid from accumulating near the snap-fit ​​portion 820, and also preventing the wall thickness of the cylindrical cup body 710 from being reduced.

[0037] See Figures 2 to 4 In some embodiments of this utility model, the overhang 200 is provided with an annular plate 250 on the outer periphery of the refrigeration evaporator 300 and the ice scraping mechanism 400. The annular plate 250 is connected to the upper edge of the circular wall plate 240. The inner peripheral wall of the circular wall plate 240 is provided with a stop strip 811 that extends approximately along the height direction of the circular wall plate 240. The lower end of the stop strip 811 is connected to a guide strip 812 that extends approximately along the circumference of the circular wall plate 240. The guide strip 812, the stop strip 811 and the annular plate 250 define the rotating slot 810. Understandably, when the latching part 820 is aligned with the entrance of the rotating slot 810, the smoothie container 700 is rotated so that the latching part 820 moves along the guide bar 812 to abut against the stop bar 811. At this time, the smoothie container 700 cannot disengage from the cantilever part 200 when subjected to vertical force. When the smoothie container 700 is rotated so that the latching part 820 moves away from the stop bar 811 and away from the entrance of the rotating slot 810, the smoothie container 700 can be pulled down to disengage from the cantilever part 200.

[0038] See Figure 4In some embodiments of this utility model, the guide strip 812 includes a first inclined segment 813 connected to the lower end of the stop strip 811 and a second inclined segment 814 connected to the first inclined segment 813. The first inclined segment 813 forms a first horizontal angle with the annular plate 250, and the second inclined segment 814 forms a second horizontal angle with the annular plate 250. The second horizontal angle is greater than the first horizontal angle. The latching part 820 is a strip-shaped protrusion inclined relative to the upper end face of the cylindrical cup body 710. The lower side of the strip-shaped protrusion is in contact with the upper side of the first inclined segment 813. It should be noted that the second horizontal angle is greater than the first horizontal angle, that is, the entrance of the rotating slot 810 forms a significantly flared trumpet shape. When one end of the strip-shaped protrusion contacts the stop strip 811, the lower side of the strip-shaped protrusion is in contact with the upper side of the first inclined segment 813, providing greater support force.

[0039] See Figure 1 In some embodiments of this invention, the housing 100 is movably provided with a water collection tray 900 located directly below the refrigeration evaporator 300 and the ice scraping mechanism 400. After the slush container 700 is removed, the ice flakes remaining on the refrigeration evaporator 300 or the liquid droplets formed by the melting of the slush fall into the water collection tray 900. In this embodiment, the water collection tray 900 is a flat box-shaped body with a detachable cover plate at the upper opening. The cover plate is covered with through holes, allowing the water in the water collection tray 900 to be poured out when it is full.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
