Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and in particular to a water pump overflow structure and a coffee machine. Background Technology

[0002] In traditional coffee machines, due to the highly compact internal structure, the water pump is often placed directly above or adjacent to the electrical components. However, traditional coffee machines lack waterproofing for these components, making it easy for leaking water from the pump to drip onto the electrical parts and cause malfunctions. Therefore, this shortcoming in coffee machines needs to be addressed. Utility Model Content

[0003] Therefore, it is necessary to provide a water pump overflow structure and a coffee machine to address the problem that traditional coffee machines do not have waterproof protection for electrical components, which can lead to water leakage from the water pump dripping onto the electrical components and causing them to malfunction.

[0004] A water pump overflow structure includes: a support assembly; an electrical assembly disposed on the support assembly; a water pump assembly disposed on the support assembly, the water pump assembly being located above the electrical assembly or adjacent to the electrical assembly; and a baffle assembly disposed on the electrical assembly and / or the water pump assembly, the baffle assembly being located between the electrical assembly and the water pump assembly, the baffle assembly having a liquid-receiving chamber and an overflow port, the liquid-receiving chamber communicating with the overflow port, the liquid-receiving chamber being located on the side of the baffle assembly facing the water pump assembly, the liquid-receiving chamber being used to collect liquid leaked from the water pump assembly.

[0005] The first aspect of this application discloses a water pump overflow structure. A baffle assembly positioned between the electrical components and the water pump assembly effectively solves the problem of waterproofing the electrical components within a compact space. Specifically, the liquid-receiving chamber on the baffle assembly directly and actively collects liquid leaking from above or to the side of the water pump assembly, thus physically isolating the path for liquid to drip onto the electrical components below. This fundamentally avoids electrical malfunctions such as short circuits and corrosion caused by liquid leakage. The overflow port connects to the liquid-receiving chamber, providing a controllable discharge path for the liquid in the chamber. This allows the liquid to be guided to a safe area in a timely manner. In the design, the liquid can be directly discharged or transported from the side of the electrical components to the bottom of the support assembly, and then discharged from the bottom of the support assembly. This effectively prevents liquid accumulation in the liquid-receiving chamber, which could lead to liquid overflow onto the electrical components, further ensuring the long-term effectiveness of protection for the electrical components. Electrical components include, for example, motors. The water pump overflow structure disclosed in this application significantly improves the reliability and safety of the product without altering the original compact layout.

[0006] In one embodiment, a water outlet connector is formed on the pump assembly, and the water outlet connector is located above the liquid receiving chamber. By positioning the water outlet connector above the liquid receiving chamber, it is ensured that liquid dripping from this critical structure, which is most likely to leak, can be directly and completely captured by the liquid receiving chamber directly below. This creates a highly efficient and reliable physical barrier between the leak source and the electrical components, preventing the electrical components from malfunctioning due to contact with liquid.

[0007] In one embodiment, the baffle assembly covers the electrical component. By covering the electrical component with the baffle assembly, a reliable protective barrier is provided to prevent liquid leaking from the upper water pump assembly from dripping onto the electrical component, greatly expanding the coverage of waterproof protection and improving the safety and reliability of the product.

[0008] In one embodiment, the support assembly has a receiving cavity and a water outlet at its bottom. The receiving cavity is configured to receive the liquid output from the overflow port, and the water outlet is connected to the receiving cavity. By providing a receiving cavity and a water outlet at the bottom of the support assembly, the liquid discharged from the overflow port of the baffle assembly is guided in an orderly manner to the receiving cavity at the bottom and finally actively discharged from the water outlet, further enhancing the overall safety protection capability.

[0009] In one embodiment, the baffle assembly includes a protective plate and a mating structure. The protective plate is disposed on the electrical assembly and has the liquid-receiving cavity and the overflow port. The mating structure is disposed on the protective plate and connected to the support assembly. The protective plate allows for the collection and diversion of leaked liquid from the pump assembly. The mating structure ensures the stable installation of the protective plate on the support assembly, thereby guaranteeing the long-term effectiveness and reliability of the liquid-receiving cavity and the overflow port, and enhancing the overall structural stability.

[0010] In one embodiment, the protective plate includes a first plate, a second plate, and a first rib. The first plate is disposed on the electrical assembly and located between the water pump assembly and the electrical assembly. The second plate is disposed on the first plate. The first rib is disposed on the first plate and extends circumferentially along the first plate. The first plate, the second plate, and the first rib enclose the liquid-receiving cavity, and the first rib has the overflow port. By forming the liquid-receiving cavity with the first plate, the second plate, and the first rib, liquid leaking from the water pump assembly can be collected while maintaining a compact structure, preventing liquid from dripping onto the electrical assembly. It is understood that even without the second plate, it is also possible to form the liquid-receiving cavity simply by using the first rib and the first plate.

[0011] In one embodiment, the protective plate further includes a second rib, which is located on opposite sides of the first plate, forming a waterproof space. The electrical component is at least partially located within this waterproof space. By positioning the electrical component at least partially within the waterproof space formed by the second rib and the first plate, a protective structure that provides lateral coverage is provided. This design not only effectively catches and blocks dripping liquid from above but also prevents liquid from splashing or overflowing from the side of the device onto the electrical component within the waterproof space. This achieves multi-directional, three-dimensional waterproof protection for the electrical component, significantly enhancing its safety and reliability in complex operating environments.

[0012] In one embodiment, the support assembly includes a base plate assembly and a support housing. The electrical components are mounted on the base plate assembly, the support housing is mounted on the base plate assembly, and the water pump assembly is mounted on the support housing. By mounting the electrical components on the base plate assembly and the water pump assembly on the support housing, a clear installation and protection space is provided between the electrical components and the water pump assembly, laying the foundation for the effective deployment of the baffle assembly. This ensures structural compactness while enhancing the stability and reliability of the entire machine.

[0013] In one embodiment, the mating structure includes a first mating part that is connected to the base plate assembly. Through the connection of the first mating part to the base plate assembly, the baffle assembly can be stably installed on the base plate assembly, enabling the baffle assembly to reliably perform its water-collecting and guiding function. It should be understood that the first mating part in this application is a latch structure, but structures with other shapes that can achieve the same function should also be within the scope of protection.

[0014] In one embodiment, the mating structure includes a second mating portion connected to the support housing. By connecting the second mating portion to the support housing, the baffle assembly can be connected to the support housing. Both the support housing and the base plate assembly can fix the baffle assembly, thereby further improving the stability and reliability of the baffle assembly and enabling it to effectively prevent leaked liquid from the pump assembly from affecting the electrical components. It should be understood that the second mating portion in this application is a mounting post, but structures of other shapes that achieve the same function should also be within the scope of protection.

[0015] In one embodiment, a first mating block and a second mating block are formed on the support housing, and the first and second mating blocks are arranged opposite to each other. The water pump assembly mates with the first and second mating blocks respectively. The oppositely arranged first and second mating blocks provide a stable installation position for the water pump assembly. Specifically, this design reliably fixes the water pump assembly, ensuring its stability during operation, effectively preventing displacement or vibration, and ensuring that important components such as the water outlet connector of the water pump assembly are always accurately positioned above the liquid-receiving cavity of the baffle assembly, thereby ensuring the reliable functioning of the entire waterproof protection system.

[0016] A coffee machine includes: a housing assembly; a heating assembly disposed on the housing assembly; and the aforementioned water pump overflow structure disposed on the housing assembly, wherein the water pump assembly of the water pump overflow structure is connected to the heating assembly via a pipe.

[0017] The second aspect of this application discloses a coffee machine in which a water pump assembly is connected to a heating assembly via a pipe, ensuring a stable supply of liquid from the water pump assembly to the heating assembly for heating. A baffle assembly prevents liquid from dripping from the connection point between the water pump assembly and the heating assembly onto the electrical components below, thus preventing malfunctions. This design maintains a compact internal layout while significantly improving the safety and reliability of the entire machine, providing long-lasting waterproof protection.

[0039] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0040] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0041] Example 1

[0042] like Figure 1-12As shown, this embodiment discloses a water pump overflow structure, including: a support assembly 1; an electrical assembly 2, the electrical assembly 2 being disposed on the support assembly 1; a water pump assembly 3, the water pump assembly 3 being disposed on the support assembly 1, the water pump assembly 3 being located above the electrical assembly 2 or adjacent to the electrical assembly 2; and a baffle assembly 4, the baffle assembly 4 being disposed on the electrical assembly 2 and / or the water pump assembly 3, the baffle assembly 4 being located between the electrical assembly 2 and the water pump assembly 3, the baffle assembly 4 having a liquid-receiving chamber 401 and an overflow port 402, the liquid-receiving chamber 401 communicating with the overflow port 402, the liquid-receiving chamber 401 being located on the side of the baffle assembly 4 facing the water pump assembly 3, and the liquid-receiving chamber 401 being used to collect liquid leaked from the water pump assembly 3.

[0043] The first aspect of this application discloses a water pump overflow structure. A baffle assembly 4, located between the electrical component 2 and the water pump assembly 3, effectively solves the problem of waterproofing the electrical component 2 within a compact space. Specifically, the liquid-receiving chamber 401 on the baffle assembly 4 can directly and actively collect liquid leaking from above or to the side of the water pump assembly 3, thereby physically isolating the path of liquid dripping onto the electrical component 2 below, fundamentally avoiding electrical malfunctions such as short circuits and corrosion caused by liquid leakage. The overflow port 402, connected to the liquid-receiving chamber 401, provides a controllable discharge path for the liquid in the liquid-receiving chamber 401, thus guiding the liquid to a safe area in a timely manner. In the design, the liquid can be directly discharged, or it can be transported from the side of the electrical component 2 to the bottom of the support assembly 1, and then discharged from the bottom of the support assembly 1. This effectively prevents liquid accumulation in the liquid-receiving chamber 401, which would cause liquid to overflow onto the electrical component 2, further ensuring the long-term effectiveness of protection for the electrical component 2. The electrical component 2 is, for example, a motor. The water pump overflow structure disclosed in this application greatly improves the reliability and safety of the product without changing the original compact layout.

[0044] like Figure 2 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a water outlet connector 31 is formed on the water pump assembly 3, and the water outlet connector 31 is located above the liquid receiving chamber 401. By placing the water outlet connector 31 above the liquid receiving chamber 401, it is ensured that the liquid dripping from the water outlet connector 31, the most likely critical structure to leak, can be directly and completely captured by the liquid receiving chamber 401 directly below, thereby constructing an extremely efficient and reliable physical barrier between the leakage source and the electrical component 2, preventing the electrical component 2 from contacting the liquid and malfunctioning.

[0045] like Figure 2-4As shown, in addition to the features of the above embodiments, this embodiment further specifies that the baffle assembly 4 covers the electrical component 2. By covering the electrical component 2 with the baffle assembly 4, a reliable protective barrier can be provided for the electrical component 2, preventing liquid leaking from the water pump assembly 3 above from dripping onto the electrical component 2, greatly expanding the coverage of waterproof protection, and improving the safety and reliability of the product.

[0046] like Figure 1 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the bottom of the support assembly 1 is provided with a receiving cavity 101 and a water outlet, the receiving cavity 101 is configured to receive the liquid output from the overflow port 402, and the water outlet is connected to the receiving cavity 101. By providing a receiving cavity 101 and a water outlet at the bottom of the support assembly 1, the liquid discharged from the overflow port 402 of the baffle assembly 4 is orderly guided to the receiving cavity 101 at the bottom, and finally actively discharged from the water outlet, further enhancing the overall safety protection capability.

[0047] like Figure 1 and Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the baffle assembly 4 includes a protective plate 41 and a mating structure 42. The protective plate 41 is disposed on the electrical assembly 2, and the protective plate 41 has the liquid-receiving cavity 401 and the overflow port 402. The mating structure 42 is disposed on the protective plate 41 and is connected to the support assembly 1. The protective plate 41 can collect the liquid leaking from the water pump assembly 3 and guide the liquid. The mating structure 42 can stably install the protective plate 41 on the support assembly 1, thereby ensuring the long-term effectiveness and reliability of the liquid-receiving cavity 401 in collecting liquid and the overflow port 402 in guiding liquid, and enhancing the stability of the overall structure.

[0048] like Figure 4 and Figure 8As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the protective plate 41 includes a first plate 411, a second plate 412, and a first rib 413. The first plate 411 is disposed on the electrical assembly 2 and is located between the water pump assembly 3 and the electrical assembly 2. The second plate 412 is disposed on the first plate 411. The first rib 413 is disposed on the first plate 411 and extends circumferentially along the first plate 411. The first plate 411, the second plate 412, and the first rib 413 enclose and form the liquid-receiving cavity 401, and the first rib 413 is provided with the overflow port 402. By forming the liquid-receiving cavity 401 by the first plate 411, the second plate 412, and the first rib 413, the liquid leaking from the water pump assembly 3 can be collected while ensuring a compact structure, preventing liquid from dripping onto the electrical assembly 2. It is understandable that even without the second plate 412, it is possible to simply use the first rib 413 and the first plate 411 to enclose and form the liquid-receiving cavity 401.

[0049] like Figure 4 and Figure 9 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the protective plate 41 also includes a second rib 414, the second rib 414 and the first rib 413 are respectively located on opposite sides of the first plate 411, the second rib 414 and the first plate 411 enclose a waterproof space 403, and the electrical component 2 is at least partially located in the waterproof space 403. By having the electrical component 2 at least partially located in the waterproof space 403 formed by the second rib 414 and the first plate 411, a protective structure that covers the electrical component 2 from the side is provided. This design can not only effectively catch and block dripping liquid from above, but also prevent liquid from splashing or overflowing from the side of the equipment from splashing onto the electrical component 2 located in the waterproof space 403, thereby achieving multi-directional and three-dimensional waterproof protection for the electrical component 2, significantly enhancing its safety and reliability in complex operating environments.

[0050] like Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the support assembly 1 includes a base plate assembly 11 and a support housing 12; the electrical assembly 2 is disposed on the base plate assembly 11; the support housing 12 is disposed on the base plate assembly 11; and the water pump assembly 3 is disposed on the support housing 12. By disposing of the electrical assembly 2 on the base plate assembly and the water pump assembly 3 on the support housing 12, a clear installation and protection space is reserved between the electrical assembly 2 and the water pump assembly 3, laying the foundation for the effective deployment of the baffle assembly 4. This enhances the stability and reliability of the entire machine while ensuring structural compactness.

[0051] like Figure 1 and Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: the mating structure 42 includes a first mating part 421, which is connected to the base plate assembly 11. Through the connection of the first mating part 421 to the base plate assembly 11, the baffle assembly 4 can be stably installed on the base plate assembly 11, enabling the baffle assembly 4 to stably perform its water-collecting and guiding function. It should be understood that the first mating part 421 in this application is a latch structure, but structures with other shapes that can achieve the same function should also be within the scope of protection.

[0052] like Figure 1 and Figure 7-8 As shown, in addition to the features of the above embodiments, this embodiment further specifies that the mating structure 42 includes a second mating part 422, which is connected to the support housing 12. By connecting the second mating part 422 to the support housing 12, the baffle assembly 4 can be connected to the support housing 12. Both the support housing 12 and the base plate assembly 11 can fix the baffle assembly 4, thereby further improving the stability and reliability of the baffle assembly 4, enabling the baffle assembly 4 to effectively prevent leaked liquid from the water pump assembly 3 from affecting the electrical assembly 2. It should be understood that the second mating part 422 in this application is a mounting post, but structures of other shapes that can achieve the same function should also be within the scope of protection.

[0053] like Figure 10 As shown, in addition to the features of the above embodiments, this embodiment further specifies that: a first mating block 121 and a second mating block 122 are formed on the support housing 12, the first mating block 121 and the second mating block 122 are arranged opposite to each other, and the water pump assembly 3 mates with the first mating block 121 and the second mating block 122 respectively. The oppositely arranged first mating block 121 and the second mating block 122 provide a stable installation position for the water pump assembly 3. Specifically, this design reliably fixes the water pump assembly 3, ensuring the stability of the water pump assembly 3 during operation, effectively preventing its displacement or vibration, and ensuring that important components such as the water outlet connector 31 of the water pump assembly 3 are always accurately positioned above the liquid receiving cavity 401 of the baffle assembly 4, thereby ensuring the reliable realization of the entire waterproof protection system function.

[0055] like Figure 13As shown, this embodiment discloses a coffee machine, including: a housing assembly 100; a heating assembly 200 disposed on the housing assembly 100; and the aforementioned water pump overflow structure disposed on the housing assembly 100, wherein the water pump assembly 3 of the water pump overflow structure is connected to the heating assembly 200 via a pipe.

[0056] The second aspect of this application discloses a coffee machine in which a water pump assembly 3 is connected to a heating assembly 200 via a pipe, ensuring that liquid at the water pump assembly 3 can be stably delivered to the heating assembly 200 for heating. A baffle assembly 4 prevents liquid from dripping from the connection point between the water pump assembly 3 and the heating assembly 200 onto the electrical assembly 2 below, thus preventing malfunction of the electrical assembly 2. This design maintains the compact internal layout of the coffee machine while significantly improving the safety and reliability of the entire machine and achieving long-lasting waterproof protection.

[0057] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
