Description

A water tank for a household cleaning machine and a household cleaning machine

[0001] This application claims priority to Chinese patent application No. 202422697275.7, filed on November 5, 2024, the entire contents of which are incorporated herein by reference.

[0002] Technical Field

[0003] This application relates to the field of automatic cleaning equipment technology, specifically a water tank for a household cleaning machine and a household cleaning machine. Background Technology

[0004] When feeding babies, baby bottles are usually used. Because babies feed frequently, the bottles need to be cleaned after each use. Manual cleaning is not only time-consuming and laborious, but also has poor cleaning effect. When using an ultrasonic cleaner to clean baby bottles, it can only clean the bottle. The residue from the cleaning process may lead to bacterial growth, which poses certain safety hazards.

[0005] Existing cleaning machines can automatically clean baby bottles and are very convenient to operate. These machines typically include a water tank and a cleaning assembly, with the water tank supplying water to the cleaning assembly. However, the water tank structure in existing technology is flawed, making it very inconvenient to add water. Summary of the Invention

[0006] This application provides a water tank for a household cleaning machine and a household cleaning machine, aiming to solve the problems of unreasonable water tank structure and inconvenient operation when adding water to the water tank in the prior art.

[0007] To solve the above-mentioned technical problems, this application proposes a water tank for a household cleaning machine, including a tank body, a cavity provided inside the tank body, an opening communicating with the cavity on the tank body, and a tank cover covering the opening on the tank body.

[0008] The lid is rotatably connected to the box body. The lid has an open state and a closed state. When the lid is in the open state, it is located on one side of the box body. When the lid is in the closed state, it is located above the box body.

[0009] In one embodiment, a one-way valve for draining water from the tank is provided at the lower end of the tank.

[0010] The one-way valve design ensures that water flows out in only one direction. When drainage is needed, water flows smoothly through the one-way valve without backflow. Once drainage is initiated, the one-way valve responds quickly, allowing water to flow rapidly, thus improving drainage efficiency. The one-way valve's anti-backflow function effectively prevents external impurities or sewage from flowing back into the water tank, ensuring the cleanliness and hygiene of the water inside. Backflow during drainage could damage the water tank and related equipment. The one-way valve prevents this, thus extending the equipment's lifespan.

[0011] In one embodiment, the one-way valve is disposed in the middle of the bottom wall of the housing, and a support rib supporting the housing is provided on the lower end of the housing. The support rib is arranged around the one-way valve, and the lower end of the one-way valve is not lower than the lower end of the support rib.

[0012] Placing the check valve in the center of the bottom wall and surrounding it with support ribs ensures a more even distribution of force on the water tank on the table. This design helps prevent the tank from tipping over or wobbling due to a shift in the center of gravity. The support ribs provide additional support points for the tank, increasing the contact area between the tank and the table, thus improving overall stability. Positioning the check valve in the center of the bottom wall and surrounding it with support ribs also protects it from external impacts or pressure, extending its lifespan. Furthermore, its central location and surrounding support ribs make maintenance or replacement of the check valve easier.

[0013] In one embodiment, the distance between the outer side of the support ridge and the outer side of the housing is greater than 0.

[0014] The presence of a certain distance between the support ridges and the enclosure effectively distributes the pressure and weight borne by the enclosure. This dispersion makes the overall structure of the enclosure more stable and able to withstand greater external loads. When subjected to external forces, the deformation of the enclosure is suppressed to a certain extent due to the supporting effect of the support ridges. As an external support structure for the enclosure, the support ridges effectively reduce the direct contact between the enclosure and the external environment. This helps prevent damage to the enclosure from scratches, impacts, etc., thereby improving the durability of the enclosure. By enhancing structural stability and improving durability, the design with a distance greater than 0 between the support ridges and the enclosure can significantly extend the service life of the enclosure. This is especially important for enclosures that require long-term use and frequent handling.

[0015] In one embodiment, the box body is further provided with a handle for easy operation of the box body, the handle being a groove recessed into the box body.

[0016] The recessed handle design allows the user's hand to naturally conform to its contours when gripping, reducing the contact area between the hand and the case surface, thus improving grip stability and comfort. This ergonomic design makes operation more convenient. Because the handle is recessed, the user's hand receives better support and cushioning during prolonged gripping or handling, reducing hand fatigue. The recessed handle design increases friction between the hand and the case, making it less likely to slip during handling, thus improving operational safety. When the case is subjected to external impact or collision, the recessed handle design reduces direct injury to the hand, providing a certain degree of protection.

[0017] In one embodiment, the housing is further provided with a grip piece for easy holding, the grip piece spanning the groove and located at the upper end of the groove, and a grip space for accommodating fingers is formed between the grip piece and the groove.

[0018] The grip plate is designed with the natural structure of the hand in mind, especially the bending and placement habits of the fingers. By spanning the groove and positioned at its top, the grip plate provides a natural support point for the fingers, making the grip more comfortable and stable. The grip space is designed to allow the fingers to bend naturally and place in a suitable position, thereby reducing the pressure on the hand during gripping. This design helps reduce hand fatigue and improves comfort during prolonged gripping. The grip space between the grip plate and the groove provides additional friction for the fingers, making the grip more secure. This helps prevent slippage when handling or moving the case, improving operational safety. The grip plate design also considers hand protection. During handling, if the case is subjected to external impact or collision, the grip plate can disperse some of the impact force, reducing direct injury to the hands.

[0019] In one embodiment, the lid is provided with a pivot, and the lid is rotatably connected to the box body via the pivot. The box body is provided with a shaft hole that mates with the pivot.

[0020] The design of the hinge and shaft hole allows the lid to rotate smoothly around the hinge, enabling quick opening and closing of the case. This design reduces resistance and inconvenience during opening and closing, improving operational efficiency. The tight fit between the hinge and shaft hole ensures a stable connection between the lid and the case, preventing accidents caused by the lid loosening during transportation or use. The hinge design reduces the direct contact area between the lid and the case, thus reducing wear and tear on the case caused by frequent opening and closing. This helps extend the service life of the case.

[0021] In addition, this application also proposes a household cleaning machine, including a base and a water tank disposed on the base, wherein the water tank is a household cleaning machine water tank as described above.

[0022] In one embodiment, the base is provided with a base plate for positioning the water tank. A rear side plate is provided on the base plate. A left side plate and a right side plate are also provided on the base plate. The left side plate and the right side plate are both located in front of the rear side plate. The rear side plate, the left side plate, and the right side plate form a positioning cavity for positioning the water tank. Guide protrusions are provided on the left side plate and the right side plate. A guide groove that cooperates with the guide protrusions is provided on the water tank.

[0023] Because the water tank is positioned on the base via the cooperation of guide grooves and guide ridges, this design makes disassembly and installation of the water tank simple and quick. When cleaning the water tank and base is required, they can be easily removed from the base for thorough cleaning before being reinstalled. This makes cleaning the water tank and base very convenient, especially the rear, left, right, and bottom panels. The design of the guide grooves and guide ridges not only simplifies the installation and disassembly process but also reduces the contact area between the water tank and the base, thus reducing cleaning dead zones. This helps ensure the cleanliness of the water tank and its surrounding area, improving overall hygiene. The cooperation of the guide grooves and guide ridges ensures precise positioning of the water tank on the base. This design eliminates positional deviations during installation, allowing the water tank to be accurately installed in the predetermined position, thereby improving the positioning accuracy of the water tank. During equipment operation, the tight cooperation of the guide grooves and guide ridges also reduces displacement of the water tank due to vibration. This helps maintain the stability and reliability of the water tank, ensuring the normal operation of the equipment. The positioning cavity formed by the base plate, rear side plate, left side plate, and right side plate provides solid support for the water tank. This design enhances the structural strength of the water tank, enabling it to withstand greater pressure and impact. The cooperation between the guide groove and the guide rib not only ensures the precise positioning of the water tank but also prevents it from shaking during equipment operation through physical constraints. This helps maintain the stability of the water tank and reduces noise and vibration caused by shaking.

[0024] In one embodiment, the base plate is further provided with a drain nozzle for positioning the water tank and for opening a one-way valve located on the water tank, the drain nozzle extending into the one-way valve.

[0025] The drain nozzle on the base plate extends directly into the check valve, allowing users to drain water without direct contact with the tank or the check valve itself. This design simplifies the drainage process, reducing steps and required tools. Users can easily complete the drainage process automatically, further enhancing ease of use.

[0026] The beneficial effects of this application are as follows:

[0027] This application utilizes a rotating lid attached to the tank body, so that when the lid is open, it is located on the side of the tank body rather than on top. This design allows users to easily add water to the tank without removing it from the device or moving it to a specific location. Users simply turn the lid to the side to expose the outlet, making it easy to fill the chamber with water. The side-opening design provides users with more operating space, making the water filling process smoother and more unobstructed.

[0028] The lid can be flexibly switched between open and closed states. When closed, the lid tightly covers the opening, preventing dust and impurities from entering the cavity and maintaining water quality; when open, it facilitates water filling. This design meets both daily use needs and ease of cleaning and maintenance. The lid rotates to the body, ensuring its stability and making opening and closing smoother, reducing noise and wear.

[0029] The side-opening tank cover design also makes it easy for users to clean and maintain the inside of the water tank. Users can easily perform cleaning without disassembling the entire water tank, reducing maintenance costs and difficulty. Attached Figure Description
