Abstract
Description
Technical Field
[0001] This application belongs to the field of nursing machine technology, specifically relating to a water channel structure and a nursing machine. Background Technology
[0002] In traditional nursing care equipment, the water system often employs a simple design with a storage tank and inlet. Excess water flows down and into the storage tank through the inlet. Because the casing is installed at the bottom of the machine's interior, unavoidable gaps exist between the casing and the internal wall. This means that during operation, water sliding down the internal wall lacks an effective flow guidance mechanism, causing it to seep into these gaps. Over time, this can damage internal components. Furthermore, it easily accumulates dirt and impurities, affecting water quality and shortening the equipment's lifespan. Utility Model Content
[0003] To address the problem of water seeping into gaps after sliding along the inner wall of the machine in the prior art, this application provides a water channel structure and a nursing machine.
[0004] This application is achieved through the following technical solution:
[0005] A water channel structure includes a chassis cover plate located at the bottom of the inner side of the machine body, a water storage tank located below the chassis cover plate, a through hole corresponding to the water storage tank on the chassis cover plate, and a slide rail inclined towards the through hole. A flow channel assembly is provided on the inner side wall of the machine body along the edge of the chassis cover plate, and the flow channel assembly is used to guide the water flowing down the inner side wall of the machine body to the water storage tank.
[0006] As described above, the water channel structure includes a first channel located on the inner rear wall of the body, a second channel and a third channel located on the inner left and right sides of the body, and a fourth channel located on the inner front wall of the body and passing above the water storage tank.
[0007] In the waterway structure described above, the horizontal height of the first flow channel is greater than that of the second and third flow channels. The first flow channel has a first gap at both its left and right ends, which allows water from the first flow channel to flow into the second and third flow channels.
[0008] In one waterway structure as described above, the first flow channel is inclined downward toward the second flow channel; or the first flow channel is inclined downward toward the third flow channel; or the left and right sides of the first flow channel are respectively inclined downward toward the second flow channel and the third flow channel.
[0009] In the waterway structure described above, the second and third flow channels are inclined downwards toward the fourth flow channel.
[0010] In the waterway structure described above, a second notch is provided on one end of the second and third flow channels corresponding to the fourth flow channel, and the second notch connects the second and third flow channels to the fourth flow channel.
[0011] In the waterway structure described above, the fourth flow channel is provided with at least one water outlet, which is provided corresponding to the water storage tank.
[0012] In the waterway structure described above, the top of the water storage tank is provided with an opening, and the water storage tank is detachably connected to the body.
[0013] In the waterway structure described above, the fourth flow channel has a third notch at both its left and right ends, and the third notch allows the second flow channel and the third flow channel to overlap on the fourth flow channel.
[0014] A nursing machine comprising a water channel structure as described in any of the preceding claims.
[0015] Compared with the prior art, this application has the following advantages:
[0016] This application discloses a water channel structure and a care machine. A water storage tank located below the machine cover, along with through holes and inclined slides, guides water dripping normally from clothes inside the machine into the water storage tank. The structure of the flow channel assembly along the edge of the machine cover can precisely constrain and guide the water flow path, allowing water sliding down the inner side wall of the machine to slide through the gap between the machine and the body and finally slide into the flow channel assembly. This ensures that the water flows in a predetermined direction under the action of gravity and finally enters the water storage tank through the through holes. This not only blocks the contact path between the water flow and the internal components of the machine, preventing equipment corrosion and electrical failures caused by long-term water seepage, but also reduces the possibility of impurities adhering and dirt accumulation.

[0022] To make the technical problems solved by this application, the technical solutions, and the beneficial effects clearer, this application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit this application.
[0023] Please see Figures 1 to 4 A water channel structure includes a chassis cover plate 2 located at the bottom inner side of a body 1, a water storage tank 3 located below the chassis cover plate 2, a through hole 4 corresponding to the water storage tank 3 on the chassis cover plate 2, and a slide 5 inclined towards the through hole 4. A flow channel group 6 is provided on the inner side wall of the body 1 along the edge of the chassis cover plate 2. The flow channel group 6 is used to guide the water flowing down the inner side wall of the body 1 to the water storage tank 3.
[0024] This application discloses a water channel structure and a care machine. A water storage tank located below the machine cover, along with through holes and inclined slides, guides water dripping normally from clothes inside the machine into the water storage tank. The structure of the flow channel assembly along the edge of the machine cover can precisely constrain and guide the water flow path, allowing water sliding down the inner side wall of the machine to slide through the gap between the machine and the body and finally slide into the flow channel assembly. This ensures that the water flows in a predetermined direction under the action of gravity and finally enters the water storage tank through the through holes. This not only blocks the contact path between the water flow and the internal components of the machine, preventing equipment corrosion and electrical failures caused by long-term water seepage, but also reduces the possibility of impurities adhering and dirt accumulation.
[0025] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the flow channel group 6 includes a first flow channel 61 disposed on the inner rear sidewall of the body 1, a second flow channel 62 and a third flow channel 63 disposed on the inner left and right sidewalls of the body 1, and a fourth flow channel 64 disposed on the inner front sidewall of the body 1 and passing above the water storage tank 3.
[0026] In this embodiment, the height difference is designed using gravity and the natural flow of water. Because the first flow channel 61 is at a higher horizontal level, when water slides down from the rear inner wall of the body 1 into the first flow channel 61, it will naturally flow under gravity towards the second flow channel 62 and the third flow channel 63, which are at lower horizontal levels. This allows the water to smoothly flow from the first flow channel 61 into the second flow channel 62 and the third flow channel 63, thereby achieving effective water distribution and guidance. The main benefits of this design are that it can efficiently guide water flow, prevent water from accumulating at the first flow channel 61, reduce disordered water flow on the inner wall of the machine body, thereby reducing the potential risk of water flow damage to internal components. It also helps to reduce the accumulation of dirt and impurities, maintain water quality, and effectively prevent water from seeping into the gap between the machine body 1 and the chassis cover 2, avoiding damage to internal components and the accumulation of dirt and impurities. Each flow channel forms a natural gravity flow system through height difference and tilt angle, which can achieve automatic flow guidance without additional power. The gap design between the flow channels ensures the continuity of water flow.
[0027] Furthermore, as a preferred embodiment of this solution and not a limitation, the horizontal height of the first flow channel 61 is greater than the horizontal height of the second flow channel 62 and the third flow channel 63. The first flow channel 61 is provided with a first notch 611 at both the left and right ends, and the first notch 611 allows water on the first flow channel 61 to flow to the second flow channel 62 and the third flow channel 63.
[0028] In this embodiment, the height difference design ensures that water flow naturally flows from the higher first flow channel 61 through the first gap 611 to the lower second flow channel 62 and third flow channel 63, achieving automatic diversion without the need for an additional power unit, thus saving energy and improving system reliability. Secondly, the symmetrical arrangement of the first gap 611 allows water flow from the rear of the machine to be evenly distributed to the left and right flow channels, avoiding the risk of overflow caused by overload of water flow on one side. At the same time, this diversion method also optimizes the water flow path, shortens the residence time of water flow in the machine, and effectively reduces the possibility of scale deposition. Furthermore, this stepped flow channel layout makes the entire flow guiding system structure more compact, maximizing the flow guiding efficiency within a limited space. From the working principle, the system cleverly utilizes gravity and water flow inertia. When the water flows down the rear wall of the machine to the first flow channel 61, it will naturally converge to the lowest point on both sides (i.e., the first gap 611), and then smoothly enter the next flow channel through the gap. In other possible embodiments, guide fins or buffer structures can be provided at the first notch 611 to optimize the smoothness of water flow when turning, reduce water splashing and noise; or the first flow channel 61 can be designed as an adjustable height structure to adapt to the flow guidance requirements under different flow conditions, which can not only further improve the flow guidance efficiency, but also reduce water flow noise and enhance the system's adaptability to different working conditions. At the same time, the adjustable height design also provides greater convenience for the maintenance and cleaning of the equipment.
[0029] Furthermore, as a preferred embodiment of this solution and not a limitation, the first flow channel 61 is inclined downward toward the second flow channel 62; or the first flow channel 61 is inclined downward toward the third flow channel 63; or the left and right sides of the first flow channel 61 are respectively inclined downward toward the second flow channel 62 and the third flow channel 63.
[0030] In this embodiment, the inclined design utilizes gravity to ensure that water flows naturally and smoothly from the first channel 61 to the second channel 62 and the third channel 63, without the need for additional power or complex guiding structures, thus simplifying the design and maintenance of the overall waterway system. When the first channel 61 is inclined towards the second channel 62, the water flows smoothly along this inclined surface to the second channel 62 and enters through the first notch 611, continuing to flow towards the water storage tank 3. Similarly, if the first channel 61 is inclined towards the third channel 63, the water will be guided to the third channel 63. When the left and right sides of the first channel 61 are inclined respectively, it can simultaneously provide a uniform water flow distribution to the second channel 62 and the third channel 63, ensuring that both channels receive an appropriate amount of water flow, thereby optimizing the overall water flow guidance efficiency. This not only accelerates the water flow and reduces the residence time of the water in the channels, but also effectively prevents backflow or overflow at the channel junctions, improving the stability and reliability of the waterway system.
[0031] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the second flow channel 62 and the third flow channel 63 are inclined downward toward the fourth flow channel 64.
[0032] In this embodiment, the inclined design utilizes gravity to naturally guide the water flow to converge in the fourth flow channel 64, avoiding the stagnation and accumulation of water in the lateral flow channel, effectively reducing the risk of bacterial growth and scale deposition caused by water accumulation; secondly, the acceleration effect generated by the inclined angle improves the water flow transmission efficiency, ensuring reliable flow guidance even under low flow conditions.
[0033] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the second flow channel 62 and the third flow channel 63 are each provided with a second notch 621 at one end corresponding to the fourth flow channel 64, and the second notch 621 connects the second flow channel 62 and the third flow channel 63 to the fourth flow channel 64.
[0034] In this embodiment, when water flows from the first channel 61 through the first notch 611 into the second channel 62 and the third channel 63 respectively, the presence of the second notch 621 allows the water to flow smoothly from the second channel 62 and the third channel 63 into the fourth channel 64 without any obstruction or backflow. This seamless design not only ensures continuous water flow but also prevents water accumulation and overflow at the channel junctions, effectively preventing water stains and potential leakage risks, ensuring that the water flow can complete the transition with minimal energy loss and in the smoothest manner. This natural guidance mechanism requires no additional power and makes full use of gravity, enabling efficient and continuous water flow in the channel group 6.
[0035] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the fourth flow channel 64 is provided with at least one water outlet 641, which corresponds to the water storage tank 3.
[0036] In this embodiment, it is ensured that all guided water flows can return to the water storage tank 3 accurately without overflowing or leaking. This fixed-point drainage design firstly eliminates the problem of water splashing that is easily caused by the traditional free-fall water method through precise alignment, keeping the inside of the equipment dry and clean; secondly, the centralized arrangement of the outlet 641 optimizes the trajectory of the final water discharge, so that the return water can enter the water storage tank 3 at the best angle.
[0037] Furthermore, as a preferred embodiment of this solution and not a limitation thereof, the top of the water storage tank 3 is provided with an opening 31, and the water storage tank 3 is detachably connected to the body 1.
[0038] In this embodiment, the top opening 31 provides the best receiving path for water to fall naturally from the outlet 641 of the fourth channel 64. The precise matching of the opening size with the channel system ensures a leak-proof recycling effect. At the same time, this top-opening structure is more effective in preventing accidental leakage during transportation compared to the side-opening design. The detachable connection method greatly improves the maintainability of the equipment. Users can easily remove the water tank 3 for thorough cleaning or replacement, avoiding the hygiene hazards of traditional fixed water tanks that are difficult to clean in hard-to-reach corners. From the perspective of user experience, this design, through a simple "push-pull" installation mechanism, not only ensures the structural stability during operation but also achieves convenient disassembly and assembly without tools.
[0039] Furthermore, as a preferred embodiment of this solution and not a limitation, the fourth flow channel 64 is provided with a third notch 642 at both its left and right ends, the third notch 642 allowing the second flow channel 62 and the third flow channel 63 to overlap on the fourth flow channel 64.
[0040] In this embodiment, the special structure of the third notch 642 first provides a precise overlapping platform for the second flow channel 62 and the third flow channel 63. Through physical limiting, it ensures a seamless transition between the flow channels, avoiding water leakage caused by connection gaps and eliminating the structural complexity and cleaning dead spots caused by the traditional use of additional connectors. This overlapping method creatively utilizes the flow channel body structure to achieve self-alignment, greatly simplifying the installation process and enabling the flow channel group 6 to be produced modularly and assembled quickly. From a fluid dynamics perspective, the chamfer or arc design at the notch can optimize the flow trajectory when the water turns, reduce turbulence and energy loss, and allow the lateral water flow to smoothly turn into the forward flow channel. When the water flow in the second flow channel 62 and the third flow channel 63 reaches the end, through the natural guidance of the third notch 642, the water flow smoothly changes 90 degrees under the action of gravity and enters the fourth flow channel 64. The structural design at the notch ensures both sufficient water passage cross section and maintains the necessary structural strength.
[0041] A nursing machine, comprising the aforementioned waterway structure.
[0042] The working principle of this embodiment is as follows:
[0043] This application discloses a water channel structure and a care machine. A water storage tank located below the machine cover, along with through holes and inclined slides, guides water dripping normally from clothes inside the machine into the water storage tank. The structure of the flow channel assembly along the edge of the machine cover can precisely constrain and guide the water flow path, allowing water sliding down the inner side wall of the machine to slide through the gap between the machine and the body and finally slide into the flow channel assembly. This ensures that the water flows in a predetermined direction under the action of gravity and finally enters the water storage tank through the through holes. This not only blocks the contact path between the water flow and the internal components of the machine, preventing equipment corrosion and electrical failures caused by long-term water seepage, but also reduces the possibility of impurities adhering and dirt accumulation.
