Description

Technical Field

[0001] This utility model relates to the field of water system accessories technology, and in particular to a misaligned filter valve structure for a water heater. Background Technology

[0002] Water heaters, as common household appliances, primarily heat cold water to a set temperature to meet daily needs. Currently, most water heaters connect directly to the tap water pipe, relying on an internal heating element to raise the water temperature before outputting it for use via a mixing valve. However, tap water often contains solid particles such as sediment, which can accumulate inside the water heater over time. This can not only clog valves and pipes, affecting normal operation, but also significantly shorten the equipment's lifespan.

[0003] To address this issue, existing technologies typically employ inlet valve bodies with built-in filters. For example, patent CN216344034U discloses an inlet connector and water heater that utilizes a typical "T"-shaped design. The inlet and outlet pipes are located on the same axis as the main valve body, while the filter section with the filter screen is arranged perpendicular to this axis. Although this structure achieves basic filtration, it still has significant limitations: firstly, the coaxial arrangement of the inlet and outlet restricts the operating space when connecting water circuit components to the water heater, hindering the movement of installation and maintenance tools; secondly, due to the constraints of the valve body structure, the longitudinal insertion depth of the filter section is limited, resulting in a small effective filter screen area and insufficient impurity holding space, making frequent cleaning or replacement more burdensome.

[0004] Therefore, further improvements are needed. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a misaligned filter valve structure for a water heater.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: a water heater misaligned filter valve structure, including: valve body, valve cap, filter core screen and filter cover; The valve body includes an inlet pipe section, an outlet pipe section, and an installation pipe section; the inlet pipe section and the outlet pipe section are staggered vertically within the installation pipe section; the installation pipe section has a filter installation cavity for embedding the filter core; the filter core is cylindrical and embedded in the filter installation cavity, separating the inlet pipe section from the filter installation cavity; the filter installation cavity extends from the inlet pipe section to one side of the outlet pipe section; the filter cover is detachably encapsulated on the top of the installation pipe section; the valve cap is detachably disposed at the inlet end of the inlet pipe section.

[0007] Optionally, the inlet pipe section and the outlet pipe section are arranged in parallel and staggered vertically along the same axial direction.

[0008] Optionally, the installation pipe section and the water inlet pipe section are inclined at an obtuse angle.

[0009] Optionally, the angle between the installation pipe section and the water inlet pipe section is between 95° and 120°.

[0010] Optionally, the angle between the installation pipe section and the water inlet pipe section is between 100° and 110°.

[0011] Optionally, the bottom of the filter mounting cavity is provided with an annular filter screen groove; the bottom end of the filter core mesh is engaged in the filter screen groove.

[0012] Optionally, the filter cover is threaded onto the top of the mounting pipe section and presses the filter core into the filter slot.

[0013] Optionally, a sealing gasket is provided between the filter cover and the installation pipe section.

[0014] Optionally, the valve cap is threaded to the inlet of the water inlet pipe section, and a sealing ring is provided between the valve cap and the water inlet pipe section.

[0015] Optionally, the valve cap is fitted with a nut for connecting to a water pipe.

[0016] The beneficial effects of this utility model are as follows: By arranging the inlet and outlet pipes in a staggered manner, the limitations of the traditional T-shaped coaxial structure are broken, providing more ample operating space for connecting water pipes and other water circuit components on both sides. This greatly facilitates the movement of installation and maintenance tools such as wrenches, improving assembly efficiency and operability. The use of a cylindrical filter core, embedded in the filter installation cavity extending from the inlet to the outlet pipe, allows for all-around filtration of the fluid flowing through the filter core. The effective filtration area is significantly larger than that of traditional sheet or shallow filter screens, not only improving filtration efficiency and flow rate but also greatly increasing the storage space for impurities, extending the cleaning or replacement cycle of the filter screen, and reducing maintenance frequency. The staggered inlet and outlet, combined with the central flow path of the cylindrical filter screen, forms a smoother flow channel, helping to reduce water flow resistance (pressure loss), thereby reducing the load on the water heater pump to a certain extent and achieving energy-saving operation.

[0024] Example Reference Figure 1The present invention proposes a misaligned filter valve structure for a water heater, comprising: a valve body 10, a valve cap 20, a filter core 30, and a filter cover 40. The valve body 10 includes an inlet pipe section 11, an outlet pipe section 12, and an installation pipe section 13. The inlet pipe section 11 and the outlet pipe are staggered in the installation pipe section 13. The installation pipe section 13 is provided with a filter installation cavity 14 for embedding a filter core screen 30. The filter core screen 30 is cylindrical and embedded in the filter installation cavity 14, separating the inlet pipe section 11 from the filter installation cavity 14. The filter installation cavity 14 extends from the inlet pipe section 11 to one side of the outlet pipe section 12. A filter cover 40 is detachably encapsulated on the top of the installation pipe section 13. The valve cap 20 is detachably disposed at the inlet end of the inlet pipe section 11.

[0025] In this invention, by arranging the inlet pipe section 11 and the outlet pipe end in a staggered manner, the limitations of the traditional T-shaped coaxial structure are broken. This provides more ample operating space for connecting water pipes and other water circuit components on both sides, greatly facilitating the movement of installation and maintenance tools such as wrenches, and improving assembly efficiency and operability. A cylindrical filter core 30 is used and embedded in the filter mounting cavity 14 extending from the inlet pipe section 11 to the outlet pipe section 12. This allows for all-around filtration of the fluid flowing through the filter core 30, resulting in a significantly larger effective filtration area than traditional sheet or shallow filter screens. This not only improves filtration efficiency and flow rate but also greatly increases the storage space for impurities, extending the cleaning or replacement cycle of the filter screen and reducing maintenance frequency. The staggered inlet and outlet, combined with the central flow path of the cylindrical filter screen, forms a smoother flow channel, helping to reduce water flow resistance (pressure loss), thereby reducing the load on the water heater pump to a certain extent and achieving energy-saving operation.

[0026] In this embodiment, the inlet pipe section 11 and the outlet pipe section 12 are arranged in parallel and staggered vertically along the same axis. From the perspective of the internal flow channel, this parallel staggered structure, combined with the central cavity of the cylindrical filter screen, can form a smoother streamlined path with fewer turns, which helps to further reduce the local resistance and pressure loss of the water flow, and makes a positive contribution to reducing the energy consumption of the water heater pump.

[0027] Furthermore, the installation pipe section 13 and the inlet pipe section 11 are inclined at an obtuse angle. The inclined installation pipe section 13 and the filter cover 40 above it naturally form a raised platform, providing more open operating space when unscrewing the filter cover 40 for maintenance, completely avoiding interference with the outlet pipe below, highlighting the user-friendly design. The inclined filter chamber naturally guides the water flow direction when entering and exiting the filter, helping to promote the sedimentation and collection of impurities towards the bottom of the filter and the area away from the inlet under the action of gravity. In addition, the obtusely angled filter core 30 also expands the contact area with the water passage of the inlet pipe section 11, increasing the effective filtration contact area.

[0028] In this embodiment, the angle θ between the installation pipe section 13 and the inlet pipe section 11 is between 95° and 120°. An angle less than 95° will approach verticality, weakening the operating space advantage and flow field optimization effect brought by the inclined arrangement; an angle greater than 120° will make the overall structure of the valve body too "flat", which may occupy unnecessary longitudinal space and is not conducive to the settling of impurities. This range ensures that while obtaining significant operational convenience and fluid guidance, the valve body structure remains compact and coordinated.

[0029] Preferably, the angle θ between the installation pipe section 13 and the inlet pipe section 11 is between 100° and 110°. At this angle, the overall shape of the valve body is most harmonious, the internal flow field is most efficient and smooth, and the water flow resistance and energy loss can be reduced to extremely low levels.

[0030] In this embodiment, the bottom of the filter mounting cavity 14 is provided with an annular filter screen groove 15; the bottom end of the filter core 30 is engaged in the filter screen groove 15. This ensures the concentricity of the filter screen within the cavity, preventing it from tilting or shaking, and guaranteeing the uniformity and stability of the filtration effect. By providing a sealing contact surface at the bottom of the groove, an effective seal is formed with the bottom end of the filter screen, strictly preventing unfiltered water from "short-circuiting" through the gap between the bottom of the filter screen and the cavity, thus thoroughly ensuring that all incoming water must be filtered by the filter screen.

[0031] Specifically, the filter cover 40 is threaded onto the upper part of the mounting pipe section 13, pressing the filter element 30 into the filter screen groove 15. By rotating and tightening the filter cover 40, a downward axial pressure is generated, firmly pressing the filter element 30 into the bottom filter screen groove 15.

[0032] Furthermore, a sealing gasket 41 is provided between the filter cover 40 and the installation pipe section 13. The addition of the sealing gasket 41 to the threaded connection provides redundancy and reliability assurance for the sealing system.

[0033] In this embodiment, the valve cap 20 is threadedly connected to the inlet of the water inlet pipe section 11, and a sealing ring 21 is provided between the valve cap 20 and the water inlet pipe section 11.

[0034] Furthermore, the valve cap 20 is fitted with a nut 50 for connecting to a water pipe. This nut 50 serves as a standardized interface, allowing for quick and direct connection to flexible hoses or external water pipes of various sizes.

[0035] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
