Description

A compact housing and snow melting machine Technical Field

[0001] This invention relates to the field of snow melting machine technology, and more particularly to a compact housing and a snow melting machine. Background Technology

[0002] Slush machines, also known as ice cream machines, are a common type of equipment widely used in commercial establishments such as restaurants and beverage shops. Traditional slush machines, typically used in commercial settings, usually include a refrigeration system, a mixing system, and a housing. The refrigeration system typically includes a condenser. The refrigerant transports the heat released when the liquid freezes to the condenser for heat dissipation. Commercial slush machines are often designed with a horizontally positioned condenser, where the copper pipe bends at both ends of the condenser are placed at the left and right ends. This ensures the refrigerant moves horizontally within the single copper pipe path. While this design minimizes the impact of gravity on the refrigerant and facilitates heat dissipation, the condenser itself is quite large. The copper pipe bends at both ends also require additional space, and additional panels are needed to cover the left and right ends of the condenser to create heat dissipation channels. To ensure sufficient heat dissipation channels, the entire slush machine needs to be designed to be quite bulky, which not only occupies a significant amount of space but also makes it difficult to transport and store.

[0003] With the improvement of living standards, more and more consumers hope to enjoy the fun of making smoothies at home. The market for home snow melters is gradually emerging, but existing commercial snow melters are too large for home use.

[0033] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It is hereby declared that the directional terms such as up, down, left, right, front, back, inside, and outside used in this text are based solely on the accompanying drawings and are not intended to specifically limit the invention.

[0034] Referring to Figure 1, this embodiment of the invention discloses a compact housing, including a chassis 1, a front panel 2, side panels 3, a rear panel 4, a support frame 5, a motor frame 6, and an outer cover 7. The front panel 2 and the rear panel 4 are detachably fixed to the front and rear sides of the chassis 1, and the side panels 3 are detachably fixed to the left and right sides of the chassis 1. The front panel 2, the rear panel 4, and the side panels 3 surround the four sides of the chassis 1, forming a split structure. Compared with the traditional integral structure, this has the advantages of dispersed connection points, smaller span of individual components, and higher overall strength. The support frame 5 is located above the chassis 1, the motor frame 6 is mounted on the support frame 5, and the outer cover 7 is connected to the motor frame 6. The motor frame 6 is used to fix the motor, and the support frame 5 is used to support the scraper and a liquid-containing cavity. The outer cover 7 covers the cavity.

[0035] The compact housing also includes a support frame 8, which supports the support frame 5 to ensure the stability of the motor and the housing cavity. In traditional snow melting machines, the support frame 5 is a single, integral structure. However, in this embodiment, the support frame 8 is a split structure. Specifically, the support frame 8 includes a front upright 81 and a rear upright 82. The front upright 81 is located at one end of the chassis 1 near the front plate 2, with its bottom connected to the chassis 1 and its top connected to the end of the support frame 5 near the front plate 2. The rear upright 82 is located at one end of the chassis 1 near the rear plate 4. The front upright 81 and the rear upright 82 are respectively positioned at the front and rear ends of the support frame 5, providing support to both ends. This saves material compared to a single, integral structure, reduces the span of the components, and achieves the corresponding support function. Furthermore, the fixed method at both ends ensures connection strength and stability.

[0036] Furthermore, in order to reduce the overall volume of the housing, the rear support frame 82 includes side support portions 821 vertically arranged on the left and right sides of the chassis 1 and a rear upper support portion 822 arranged above the two side support portions 821. The side support portions 821 and the rear upper support portion 822 form a gate-shaped structure, and the condenser 91 of the refrigeration system 9 is arranged between the two side support portions 821. The rear support frame 82 is used to fix the condenser 91. The condenser 91 includes copper pipe elbows 911. In traditional snow melting machines, the condenser 91 is typically placed horizontally, with the copper pipe elbows 911 positioned on the left and right sides. Each copper pipe is horizontally connected between these elbows. The refrigerant moves horizontally within the condenser 91. The end plates 912 of the condenser 91 are also located on the left and right sides, and are fixed to the condenser 91 by these plates. Because a heat dissipation channel 83 needs to be formed and the condenser needs to connect to the end plates 912, space must be reserved on both sides of the condenser 91 for the copper pipe elbows 911 and for the connection and fixing of the end plates 912. Therefore, traditional snow melting machines have relatively wide left and right sides. In this embodiment of the invention, the copper pipe elbows 911 are located on the top of the condenser 91. The condenser 91 is placed vertically on both sides. The end plates 912 of the condenser 91 are located on the upper and lower sides. The condenser 91 can be fixed by the support frame 5 and the bottom of the rear upright frame 82. There is no need to reserve storage space and installation space for copper pipe elbows 911 on the left and right sides of the condenser 91. Since the height of the structure itself is sufficient to accommodate the height of the condenser 91 after it is placed vertically, the overall volume can be reduced by reducing the width of the left and right sides. Moreover, the two side support parts 821 form a heat dissipation channel 83. The bottom of the side support part 821 is connected to the chassis 1, and the rear upper support part 822 abuts against the bottom of the support frame 5. The side support part 821 not only supports the support frame 5, but also forms a heat dissipation channel 83, realizing multiple uses, saving plates, and achieving the effect of reducing volume and making the structure compact.

[0037] The beneficial effects of the embodiments of the present invention are as follows:

[0038] The compact housing of this invention includes a chassis 1, a front panel 2, side panels 3, a rear panel 4, a support frame 5, a motor frame 6, an outer cover 7, and a support frame 8. The support frame 8 includes a front upright 81 and a rear upright 82, which support the support frame 5. The support frame 5 supports the motor frame 6, and the motor frame 6 securely supports the motor. Further, the rear upright 82 includes side support portions 821 vertically arranged on the left and right sides of the chassis 1, and a rear upper support portion 822 located above the two side support portions 821. The condenser 91 of the refrigeration system 9 is fixed... The copper tube elbows 911 of the condenser 91 are located between the two side support parts 821 and are located on the upper and lower sides of the condenser 91, i.e., in a vertical manner. The condenser 91 is fixed by the upper and lower sides, and the two side support parts 821 limit the two sides of the condenser 91. They also combine to form a heat dissipation channel 83 and can support the upper rear support part 822 and the support frame 5, achieving the effect of multiple uses in one piece. This can save plates and save the space on the left and right sides of the condenser 91 used to fix and cover the copper tube elbows 911, thus achieving the effect of reducing volume and making the structure compact.

[0039] Specifically, referring to Figure 2, the chassis 1 has a front mounting portion 11 and a rear mounting portion 12 at its front and rear ends, respectively. The front mounting portion 11 has a first upright limiting groove 111 with its opening facing upwards. The bottom of the front upright 81 has an "L"-shaped front mounting angle iron 811. The opening of the first upright limiting groove 111 corresponds to the shape of the bottom of the front mounting angle iron 811. During installation, the bottom of the front mounting angle iron 811 can be inserted into the first upright limiting groove 111, forming a limiting effect. The first upright limiting groove 111 has a first upright fixing hole 112. After limiting, the front mounting angle iron 811 can be fixed in the first upright fixing hole 112 using screws or other fasteners. The limiting effect facilitates the installation and fixing of the front upright 81.

[0040] Additionally, referring to Figure 3, the rear mounting part 12 is provided with a second upright limiting groove 121, the opening of the second upright limiting groove 121 is set upward, and a second upright fixing hole 122 is provided on the outer side of the second upright limiting groove 121. The bottom of the rear upright 82 is provided with a vertically set rear insert plate 823, the rear insert plate 823 extends downward, and a rear mounting fixing plate 824 is provided on the side of the rear insert plate 823. The rear mounting fixing plate 824 protrudes outward from the surface of the rear insert plate 823 towards the outer side of the rear upright 82. The rear insert plate 823 and the rear mounting fixing plate 824 form an "L" shape. During installation, the rear insert plate 823 can be inserted into the second upright limiting groove 121 to form a limiting effect. Then, using screws or other fasteners, the rear mounting fixing plate 824 is fixed in the second upright fixing hole 122, thereby facilitating the fixing of the rear upright 82.

[0041] When installing the support frame 5, the support frame 5 is provided with a front support mounting part 51 and a rear support mounting part 52 on its front and rear sides, respectively. The front support mounting part 51 is provided with a vertically arranged front limiting post 511. The top of the front upright 81 is provided with a crossbar 812. The crossbar 812 is provided with an upright limiting hole 813 and a third upright fixing hole 814. The front limiting post 511 extends downward. When installing the support frame 5, the front limiting post 511 can be inserted into the upright limiting hole 813. The front connector limits the front limiting post 511. Then, fasteners are used to fix the front support mounting part 51 into the third upright fixing hole 814.

[0042] On the other hand, referring to Figure 4, the top of the rear support frame 82 is provided with a rear upper support part 822, and the side of the rear support mounting part 52 is provided with a vertically arranged first rear limiting post 521. The first rear limiting post 521 and the rear support mounting part 52 form a rear limiting groove 522. During installation, the rear upper support part 822 can be inserted into the rear limiting groove 522, thereby limiting the rear support mounting part 52. The rear upper support part 822 is provided with a horizontally arranged rear upper protruding fixing hole 825. Using fasteners, the rear support mounting part 52 is fixed in the rear upper protruding fixing hole 825.

[0043] The installation of the front support 81, the rear support 82, and the support frame 5 all use a method of limiting before fixing, which makes installation and disassembly convenient. Moreover, the limiting structure can improve the connection stability, thereby further improving the structural strength.

[0044] A vertically arranged rear limiting plate 826 is also provided on the side of the rear upper support portion 822 away from the first rear limiting post 521. A vertically arranged second rear limiting post 523 is also provided at the bottom of the rear support mounting portion 52. After the rear support mounting portion 52 is installed, the side of the second rear limiting post 523 can abut against the side of the rear limiting plate 826, and the bottom of the rear support mounting portion 52 abuts against the upper edge of the rear limiting plate 826. The rear limiting groove 522 and the second rear limiting post 523 form a horizontal limiting of the rear support mounting portion 52, and the rear limiting plate 826 forms a vertical limiting and support of the rear support mounting portion 52.

[0045] The rear support frame 82 also includes a lower rear protrusion 827, which is located between the two side support portions 821 and below the upper rear support portion 822. The side support portions 821, the upper rear support portion 822, and the lower rear protrusion 827 form a "U" shape. The condenser 91 is also provided with end plates 912 on its upper and lower sides. The end plates 912 are used to fix the copper pipe and the copper pipe elbow 911. In addition, the condenser 91 can be fixed by the end plates 912. The end plates 912 are fixed to the upper rear support portion 822 and the lower rear protrusion 827 respectively. Fixing the end plates 912 to the upper and lower sides of the rear support frame 82 can save space on the left and right sides of the rear support frame 82. Moreover, the height of the rear support frame 82 itself can accommodate the vertically placed condenser 91, thus reducing the overall volume.

[0046] Further, referring to Figure 5, the rear support frame 82 has a front groove 828 and a rear groove 829 on its front and rear sides, respectively. The front groove 828 and the rear groove 829 are interconnected through the heat dissipation channel 83. The refrigeration system 9 also includes a cooling fan 92, which is located in the front groove 828, and the condenser 91 is located in the rear groove 829. The cooling fan 92 can dissipate heat from the condenser 91 through the heat dissipation channel 83. The rear support frame 82 serves to support the support frame 5, form the heat dissipation channel 83 for convenient heat dissipation, and fix the cooling fan 92 and the condenser 91. Therefore, it has a multi-purpose function, further saving space for the installation and fixation of the cooling fan 92 and the condenser 91.

[0047] Referring to Figure 6, in order to connect and fix the side plate 3, the left and right sides of the chassis 1 are respectively provided with bottom limiting grooves 13, the openings of the bottom limiting grooves 13 are set downwards, and the bottom of the side plate 3 is provided with a bottom limiting cylinder 31. The bottom limiting cylinder 31 can be inserted into the bottom limiting groove 13. During installation, the chassis 1 is inserted into the bottom of the side plate 3 from top to bottom, so that the bottom limiting cylinder 31 is inserted into the bottom limiting groove 13 to form a limit. The bottom limiting groove 13 is provided with a bottom fixing hole 131. Using screws or other fasteners, the bottom limiting cylinder 31 can be fixed in the bottom fixing hole 131.

[0048] Furthermore, referring to Figure 7, bottom limiting ribs 32 arranged along the front-back direction are provided between the plurality of bottom limiting cylinders 31, and bottom limiting long grooves 14 arranged along the front-back direction are provided between the plurality of bottom limiting grooves 13. After the chassis 1 is inserted into the bottom of the side plate 3 from top to bottom, the bottom limiting ribs 32 can be inserted into the bottom limiting long grooves 14. The bottom limiting ribs 32 and the bottom limiting long grooves 14 play a further limiting role, so that after the side plate 3 and the chassis 1 are limited, the side plate 3 will not tilt, which is convenient for subsequent screw connection, and also strengthens the connection strength of large-format panels after connection.

[0049] Referring to Figure 7, the top of the side plate 3 is provided with an upper limit groove 33, which is arranged along the front-back direction and the opening of the upper limit groove 33 faces upward. The top edge of the support frame 5 is provided with an upper limit rib 53, which is arranged along the front-back direction and extends downward. During installation, the upper limit rib 53 can be inserted into the upper limit groove 33 to form a limit, and at the same time improves the connection strength.

[0050] The motor frame 6 has a vertically arranged frame limiting post 61 at its bottom. The support frame 5 has a frame fixing part 54 with a frame limiting hole 541. During installation, the frame limiting post 61 can be inserted into the frame limiting hole 541 to form a limit. The frame limiting hole 541 can also be used to fix the frame limiting post 61. The frame fixing part 54 also has a heat dissipation hole 542 for cooling the motor.

[0051] The front side of the side plate 3 is provided with a plurality of front fixing hooks 34. The front fixing hooks 34 are hook-shaped and extend upward at the end. The left and right sides of the front plate 2 are provided with front upright plates 21. The front upright plates 21 are provided with a plurality of side fixing holes 211. The horizontal span of the side fixing holes 211 gradually decreases from bottom to top. During installation, the front fixing hooks 34 can be inserted into the side fixing holes 211 to form a certain limiting effect. Then, the front upright plates 21 are pulled down, and the front fixing hooks 34 move towards the upper part of the side fixing holes 211. Since the horizontal span of the side fixing holes 211 gradually decreases from bottom to top, the upper part of the narrowed side fixing holes 211 can finally clamp the front fixing hooks 34 to form a fixed connection.

[0052] On the other hand, the rear edge of the side plate 3 is provided with a plurality of rear fixing hooks 35, the ends of the rear fixing hooks 35 extend toward the rear side, and the left and right sides of the rear plate 4 are provided with vertically arranged rear limiting grooves 41, and the ends of the rear fixing hooks 35 can be inserted into the rear limiting grooves 41 to form a fixed connection.

[0053] Referring to Figure 6, the front side of the chassis 1 is provided with a front fixing hole 15, and the rear side of the front plate 2 is provided with a front fixing buckle 22. The end of the front fixing buckle 22 extends upward, and during installation, the front fixing buckle 22 can be fastened into the front fixing hole 15. The rear side of the chassis 1 is provided with a rear boss 16, which protrudes towards the rear side of the chassis 1. The rear boss 16 is provided with a rear protrusion hole 161, and the rear plate 4 is fixed in the rear protrusion hole 161. When installing the rear plate 4, the rear plate 4 first abuts against the rear boss 16, and then fasteners are used to connect the rear plate 4 to the rear protrusion hole 161. The rear boss 16 serves to limit and support the load.

[0054] The outer cover 7 is inserted into the support frame 5 in a horizontal direction. To facilitate the installation of the outer cover 7, sliding plates 71 are provided on both the left and right sides of the outer cover 7, which are arranged in a front-back direction. The sliding plates 71 protrude from the side of the outer cover 7. The inner side wall of the support frame 5 is provided with a groove 55, the position of which corresponds to the position of the sliding plate 71. When inserted horizontally, the sliding plate 71 can be inserted into the groove 55. The groove 55 limits the sliding plate 71, allowing the outer cover 7 to be inserted horizontally and accurately. The end of the groove 55 is provided with a stop plate 551. After being inserted to the limit position, the sliding plate 71 can abut against the stop plate 551, thereby limiting the movement of the outer cover 7.

[0055] This invention also discloses a snow melting machine (not shown in the accompanying drawings), including the compact housing described above. This compact housing can also be applied to ice cream machines, etc. The compact housing is provided with a support frame 8, which includes a front support frame 81 and a rear support frame 82.
