Description

Technical Field

[0001] The subject matter of the present disclosure generally relates to systems and methods for pool pumps. Background Art

[0002] Various pools use pumps to circulate and / or filter liquid. In some cases, the pump converts electrical energy into mechanical energy as a rotating impeller pushes the liquid. As the liquid passes from one or more inlets located within the pool through the pump and then back to the pool via at least one outlet, the rotating impeller creates pressure in the liquid. The one or more inlets may include one or more skimmers or drains.

[0003] When the liquid passes through the pump, air may be released from the liquid. If the air becomes trapped in the piping or hoses, it can disrupt the flow of the liquid. If trapped near the impeller, the air can also disrupt the flow of the liquid and / or damage the impeller or pump.

[0004] Known pumps use a pressure relief valve to release air, where the pressure relief valve is manually operated by the user. The pressure relief valve can release air from the pump so that the liquid can flow through the pump. This can occur (for example) when air is expelled from the pump as the liquid is initially pumped out. In prior art systems, the manual operation of the pressure relief valve can be accomplished by turning a screw to expel air from the pump. This can occur (for example) during normal operation when air is introduced into the liquid and must be expelled. Due to the use of a screw, the screw can become stuck, cross-threaded, or degraded due to repeated use over time. The defect of the screw can cause the entire unit to need to be replaced to operate as intended. Accordingly, it is desirable to provide a simpler system for releasing air that is more convenient and has fewer problems over time. Additionally, it is desirable to reduce the number of components to increase the lifespan of the product by reducing the areas of problems. It is also desirable to allow for automatic air release without manual operation. It is further desirable to prevent debris from entering the pump. Summary of the Invention

[0034] It should be understood that the above general description and the following detailed description are only exemplary and explanatory, and are not restrictive of the scope of the present invention. Detailed Description of the Invention

[0035] Exemplary embodiments will now be described in detail, some of which are illustrated in the accompanying drawings.

[0036] To facilitate understanding of the principles and features of the present invention, each illustrative embodiment will be explained below. In particular, the subject matter of the present disclosure will be described in the context of systems and methods for operating a pool pump.

[0037] The disclosed exemplary embodiments include devices, systems, and methods for releasing air from a liquid pump. As used herein, the term air may refer to exhaust gas released from a liquid, including a gas or a gas mixture. The liquid pump may be a pool pump configured to operate near a pool. The liquid pump may be configured to receive liquid from the pool and provide the liquid back to the pool.

[0038] Reference will now be made to the accompanying drawings, in which like reference numerals refer to like parts throughout the figures, and the pool assembly will be described in detail. Figure 1 A pool pump according to some embodiments of the present disclosure is shown.

[0039] Specifically, Figure 1Illustrates an exemplary pool pump 100 in accordance with some embodiments of the present disclosure. The pool pump 100 may include a body 102. The body 102 may include an inlet 104 and an outlet 106. In some embodiments, the pool pump 100 may be configured to filter the liquid contained within the liner, e.g., to remove debris and / or particulate matter. In some embodiments, the pool pump 100 may be configured to mix chemicals into the liquid, e.g., by introducing a certain amount of chemical mixture to treat the liquid. In some embodiments, the pool pump 100 may be configured to release the chemical mixture into the liquid over time. The body 102 may be attached with one or more hoses to receive liquid from the inlet 104 along the liquid inlet direction 110 and to provide liquid from the outlet 106 along the liquid outlet direction 112.

[0040] The body 102 may be configured to stand beside the pool. In some embodiments, the body 102 may be attached to a base configured to be placed at the edge of the pool. In some embodiments, the body 102 may be attached to one or more of the frame or the liner of the pool.

[0041] The body 102 may include a release top cover 108. The release top cover 108 may automatically loosen to release the exhaust generated by the liquid flowing through the pool pump 100 (e.g., from the inlet 104 to the outlet 106).

[0042] Figure 2 Illustrates a cross-sectional view of a pool pump with a floating body in accordance with some embodiments of the present disclosure. Certain features of the pool pump 100 may be shown but not necessarily discussed herein, to the extent that they are the same as Figure 2 shown but not necessarily discussed herein, to the extent that they are the same as Figure 1 shown.

[0043] The pool pump 100 may include an impeller 120. The impeller 120 may be configured to rotate to cause the liquid to flow continuously through the pool pump 100. The impeller 120 may be connected to an electric motor 122. The electric motor 122 may be powered, for example, by a battery or an electrical connection to a power outlet.

[0044] When the liquid flows through the impeller 120, air is released from the liquid and trapped in a chamber (or floating body chamber) 124. The release top cover 108 may be mechanically connected to the floating body 114, a first seal 116, and a second seal 118. For example, the release top cover 108 may be connected to the floating body 114, the first seal 116, and the second seal 118 by a handle 138. The handle 138 may pass through an orifice of the release top cover 108. The handle 138 may be a component of the floating body 114. In some embodiments, the handle 138 may seal the orifice when it moves. In some embodiments, there is a plug 134 within the handle 138. The plug 134 may be configured to enclose the floating body 114 and isolate it from the external environment. In some embodiments, the floating body 114 may be enclosed and isolated from the external environment by at least one of an adhesive, a sealant, a cap, a cover, or a combination thereof.

[0045] In some embodiments, the first seal 116 and the second seal 118 may be configured to each seal an orifice associated with the handle 138. For example, when the first seal 116 engages around the orifice, the first seal 116 prevents air from moving from the chamber (or float body chamber) 124 to the external environment. The first seal 116 may engage when the second seal 118 is not engaged, and the second seal 118 may engage when the first seal 116 is not engaged. In some embodiments, the first seal 116 and the second seal 118 may be larger than the orifice. In some embodiments, the first seal 116 and the second seal 118 may be at least partially inserted into the orifice. In some embodiments, the orifice may penetrate one or more components (e.g., a lid, a portion of the body 102).

[0046] Figure 3 A perspective view of a float body having a handle and a plug is shown in accordance with some embodiments of the present disclosure. Certain features of the pool pump 100 may be shown but not necessarily discussed herein, to the extent that they are the same as Figure 3 those shown but not necessarily discussed herein, to the extent that they are the same as Figure 1 those shown.

[0047] The pool pump 100 may include a float body 114. The float body 114 may be configured to provide an upward force and a downward force to seal the pool pump 100 against discharge of liquid. In some embodiments, the float body 114 may be made of plastic, rubber, plastic composite, metal, or a combination thereof. In some embodiments, the float body 114 may be installed in the pool pump 100 by inserting the float body into a central hole of the pool pump 100. Although the float body 114 is depicted as having a circular cross-section, other shapes such as triangular, quadrilateral, pentagonal, hexagonal, or octagonal shapes may also be contemplated.

[0048] In some embodiments, the float body 114 is formed by molding, where the molding includes at least one of blow molding or injection molding. Blow molding of the float body 114 may include inserting a parison containing a fusible material into a mold. The fusible material is selected from the group consisting of plastic, rubber, plastic composite, or a combination thereof. After placing the parison in the mold, the temperature and pressure inside the mold are controlled to increase. The temperature is increased by heating the parison. The pressure is increased by introducing fluid pressure through an inlet of the parison. Once the molding temperature and pressure are reached, the fusible material conforms to the shape of the mold, thereby forming the float body. In some embodiments, the inner surface of the mold corresponds to the outer surface of the float body.

[0049] Injection molding of the float body 114 may include melting a fusible material and then injecting the molten material into a mold. After injection, the injected molten material is compressed to form the float body. After forming the float body 114, the float body 114 is removed from the mold. In some embodiments, after injection molding, the handle is connected to the float body by at least one of ultrasonic welding or gluing.

[0050] The pool pump 100 may include a plug 134. The plug 134 may be configured to prevent water or small particles from entering the float 114. In some embodiments, the plug 134 may be porous or non-porous. In some embodiments, the plug 134 includes at least one of rubber or a waterproof material. In some embodiments, for assembling the pool pump 100, the plug 134 is inserted into the handle 138 of the float 114. In some embodiments, the plug 134 may be at least partially located within the handle 138. In some embodiments, for assembling the pool pump 100, the plug 134 is ultrasonically welded to the handle of the float 114 to enclose the float 114.

[0051] Figure 4 A perspective view of a float and a second seal of a pool pump according to some embodiments of the present disclosure is shown. Certain features of the pool pump 100 may be shown in Figure 4 but not necessarily discussed herein, to the extent that they are the same as Figure 1 the same.

[0052] The pool pump 100 may include a second seal 118. The second seal 118 may be configured to prevent liquid from leaving the discharge hole. The second seal 118 may be formed of a material selected from the group consisting of rubber, silicone, or thermoplastic. In some embodiments, the pool pump 100 may be assembled by a method that includes the step of placing the second seal 118 around the handle 138 of the float 114. In some embodiments, the float 114 supports the second seal 118. In some embodiments, the second seal 118 is bonded to the float 114 using an adhesive. Although the second seal 118 is depicted as circular, other shapes such as triangular, quadrilateral, pentagonal, hexagonal, or octagonal shapes may also be contemplated.

[0053] Figure 5 A cross-sectional view of a float, a second seal, and a pump top cover of a pool pump according to some embodiments of the present disclosure is shown. Certain features of the pool pump 100 may be shown in Figure 5 but not necessarily discussed herein, to the extent that they are the same as Figure 1 the same.

[0054] The pool pump 100 may include a pump top cover 136. The main body 102 may include the pump top cover 136. The pump top cover 136 may be configured to cover the floating body 114 while providing an exhaust hole 132 and a sealing wall 130 to allow exhaust gas to pass through. The pump top cover 136 may be installed and fixed to the floating body housing 126 through a snap assembly or a threaded connection. The floating body housing 126 defines a chamber or floating body compartment 124 for accommodating the floating body 114. In some embodiments, the release top cover 108 and the first seal 116 are connected to the pump top cover 136. In some embodiments, the pump top cover 136 may be formed of a plastic selected from the group consisting of polypropylene, polyethylene terephthalate, polyvinyl chloride, polyethylene, polystyrene, polycarbonate, rubber, silicone, or acrylonitrile-butadiene-styrene. In some embodiments, the pump top cover 136 may be formed of a plastic composite material, plastic, metal, or a combination thereof. Although the pump top cover 136 is depicted as circular, other shapes such as triangular, quadrilateral, pentagonal, hexagonal, or octagonal shapes are also conceivable.

[0055] Figure 6 A perspective view of the first seal and the release top cover of a pool pump according to some embodiments of the present disclosure is shown. Certain features of the pool pump 100 may be shown but not necessarily discussed herein, to the extent that they are the same as Figure 6 shown but not necessarily discussed herein, to the extent that they are the same as Figure 1 those shown.

[0056] The pool pump 100 may include a release top cover 108. The release top cover 108 may be configured to cover the exhaust mechanism and prevent dust or unwanted small particles from entering the exhaust mechanism. The release top cover 108 may include a central handle for receiving the first seal 116 on its lower side. Although the release top cover 108 is depicted as circular, other shapes such as triangular, quadrilateral, pentagonal, hexagonal, or octagonal shapes are also conceivable. The release top cover 108 may be formed of a plastic selected from the group consisting of polypropylene, polyethylene terephthalate, polyvinyl chloride, polyethylene, polystyrene, polycarbonate, rubber, silicone, or acrylonitrile-butadiene-styrene. In some embodiments, the release top cover 108 may be formed of a plastic composite material, plastic, metal, or a combination thereof. The release top cover may be locked to the floating body through card columns, snap connections, or self-tapping threads. In some embodiments, the release top cover 108 may be replaced with a screw or a buckle to achieve a similar effect.

[0057] The pool pump 100 may include a first seal 116. The first seal 116 may be configured to prevent air and small dust particles in the environment from entering the pump through the exhaust holes. The first seal 116 may be formed of a material selected from the group consisting of rubber, silicone, or thermoplastic. In some embodiments, the pool pump 100 may be assembled by a method that includes the step of placing the first seal 116 around the handle of the release top cover 108. In some embodiments, the release top cover 108 and / or the pump top cover support the first seal 116. In some embodiments, the first seal 116 is bonded to the release top cover 108 using an adhesive. Although the first seal 116 is depicted as circular, other shapes may also be contemplated, such as triangular, quadrilateral, pentagonal, hexagonal, or octagonal shapes.

[0058] Figure 7 A perspective view of a float housing and a float valve of a pool pump according to some embodiments of the present disclosure is shown. Certain features of the pool pump 100 may be shown Figure 7 but not necessarily discussed herein, to the extent that they are the same as Figure 1 each other.

[0059] The pool pump 100 may include a float housing 126. The float housing 126 may be configured to protect the float 114 and prevent larger debris from entering the exhaust mechanism. The float housing 126, in combination with the float 114, the pump top cover 136, and the first seal 116 (or the second seal 118), is configured to define a chamber or float chamber 124. The float housing 126 may be formed of a plastic selected from the group consisting of polypropylene, polyethylene terephthalate, polyvinyl chloride, polyethylene, polystyrene, polycarbonate, rubber, silicone, acrylonitrile-butadiene-styrene, or combinations thereof. In some embodiments, the float housing 126 may be formed of a plastic composite, plastic, metal, or combinations thereof. The float housing 126 may be connected to the pump top cover 136 by a snap mechanism or a self-tapping screw locking mechanism to install the float housing 126 in the pool pump 100.

[0060] The pool pump 100 may include a float chamber valve 128. The float chamber valve 128 may be configured to restrict the flow of gas into the float chamber 124. Additionally, the float chamber valve 128 may be configured to prevent the float 11 from rapidly rising due to air thrust and prematurely clogging the vent hole. The float chamber valve 128 may be composed of a valve, a plate, and at least one outlet. In some embodiments, the valve and the plate are configured to rise and fall when fluid is introduced into the float chamber 124. In some embodiments, when gas enters the float chamber 124 through the valve, the at least one outlet is sealed by the plate of the float chamber valve 128. In some embodiments, when the liquid level in the float chamber 124 is below a predetermined first height, the at least one outlet is in fluid communication with the float chamber 124 and the outlet 106 of the pump. In some embodiments, the at least one outlet surrounds at least a portion of the float chamber valve 128.

[0061] The float chamber valve 128 may be formed of a plastic selected from the group consisting of polypropylene, polyethylene terephthalate, polyvinyl chloride, polyethylene, polystyrene, polycarbonate, rubber, silicone, acrylonitrile-butadiene-styrene, or combinations thereof. In some embodiments, the float chamber valve 128 may be formed of a plastic composite, plastic, metal, or combinations thereof. The float chamber valve 128 may be installed in the float chamber housing 126 by connecting the float chamber valve 128 to the float chamber housing 126 through a snap mechanism or a self-tapping screw locking mechanism.

[0062] Figures 8A - 8F A cross-sectional view of a pool pump in different modes of discharging gas from the pool pump according to some embodiments of the present disclosure is shown. Figures 8A - 8F Certain features of some parts of the illustrated pool pump 100 may be shown in Figures 8A - 8F but may not necessarily be discussed herein, to the extent that they are the same as Figure 1 or not.

[0063] Figure 8A The first mode 810 is depicted. The first mode 810 may be associated with a position where one or more vent holes 132 of the float chamber are sealed. The first mode 810 may be associated with a mode in which there is substantially no force driving the first seal 116 upward. In the first mode 810, the first seal 116 may sealingly contact the sealing wall 130 of the pump top cover 136. In the first mode 810, the float chamber valve 128 may be in a position where the valve and at least one outlet of the float chamber valve 128 are in fluid connection with the float chamber 124 and the outlet 106 of the pump. The float 114 is located at a position that allows gas to flow around the float 114 and through the gap between the second seal 118 and the pump top cover 136. In the first mode 810, the first seal 116 may be engaged to seal one or more vent holes 132. For example, the first seal 116 may be engaged with a portion of the main body 102 (e.g., the surface of the sealing wall 130). In the first mode 810, the second seal 118 may not be engaged.

[0064] Figure 8B Depicts a second mode 820. The second mode 820 may be associated with a position where the release top cover 108 and the first seal 116 are driven upward by an upward force of gas from the inlet float chamber 124. For example, in the second mode 820, the release top cover 108 may not protrude from the fixed part of the main body 102 (such as the pump top cover 136). When the pond pump 100 starts to fill with fluid, the float chamber valve 128 rises to seal the at least one outlet while allowing fluid to pass through the valve. When gas rushes into the float chamber 124 from the float chamber valve 128, the first seal 116 is opened by an upward force of gas from the inlet float chamber 124. Then, the gas is discharged from the vent hole 132 connecting the float chamber 124 to the surrounding environment.

[0065] Figure 8C Depicts a third mode 830. The third mode 830 may be associated with a position where the release top cover 108 and the first seal 116 are driven upward by an upward force acting on the float 114. For example, in the third mode 830, the release top cover 108 may protrude from the fixed part of the main body 102 (such as the pump top cover 136). The upward force acting on the float 114 may be the buoyancy force generated by the liquid filling the float chamber 124. In some embodiments, the float 114 may be filled with air, resulting in an upward force acting on the float 114 when surrounded by water. In some embodiments, during the third mode 830, after the pond pump 100 starts to fill with fluid, the float chamber valve 128 maintains the seal on the at least one outlet while allowing fluid to pass through the valve into the float chamber 124.

[0066] Figure 8D Depicts a fourth mode 840. The fourth mode 840 may be associated with a position where the float 114 reaches its highest point, at which the second seal 118 seals the gap between the second seal 118 and the pump top cover. In the fourth mode 840, the second seal 118 may be configured to prevent water from flowing out of the vent hole 132. In addition, the fourth mode 840 may be associated with the completion of the exhaust operation. The exhaust is generated by the liquid flowing through the pond pump and can be released by operating the pond pump as described herein. The exhaust operation represents a cycle of releasing gas formed by operating the pond pump, where the gas is released from inside the pond pump to the external environment.

[0067] Figure 8E Depicts a fifth mode 850. The fifth mode 850 may be associated with a position where the release top cover 108 is driven downward by a downward force on the release top cover 108 and / or the float 114. For example, the release top cover 108 may be driven downward by the suction pressure. The suction pressure is generated when the liquid entering the pond pump is less than the liquid leaving the pond pump. For example, when the pond pump inlet (such as Figures 1 - 2This can occur when there is a blockage upstream of the inlet 104 depicted. For example, the blockage may stem from a dirty filter or debris. In some embodiments, when the liquid level in the float chamber 124 drops, the release top cover 108 and / or the float 114 will descend. In some embodiments, the float chamber valve 128 can be driven downward by a suction pressure or by gravity. When the float chamber valve 128 is driven downward, at least one outlet of the float chamber valve 128 becomes fluidly connected to an inlet or an outlet of the pump body (e.g., Figures 1 - 2 the inlet 104 or the outlet 106 depicted). In some embodiments of the fifth mode 850, the first seal 116 and the second seal 118 can both be in an open configuration, where the vent hole 132 is not blocked or engaged.

[0068] Figure 8F The sixth mode 860 is depicted.

[0091] Figures 15A - 15DA cross-sectional view of a pool pump in different modes of releasing exhaust from the pool pump according to some embodiments of the present disclosure is shown. Figure 1 Certain features of some parts of the illustrated pool pump 1500 may be shown in Figures 8A - 8F but are not necessarily discussed herein, to the extent that they are the same as Figure 1 or not.

[0092] Figure 15A The first mode 1510 is depicted. The first mode 1510 may be associated with a position where the exhaust mechanism is substantially sealed. The first mode 1510 may be associated with the release top cover 908 being in a raised or unpressed state. In the first mode 1510, the second seal 918 may be in a substantially engaged state, where the second seal 918 seals the gap between the second seal 918 and the surface of the pump top cover 936. In some embodiments, the lowest surface of the plug 924 is located below the lowest surface of the pump top cover 936. In the first mode 1510, the first seal 916 may be in a disengaged state.

[0093] Figure 15B The second mode 1520 is depicted. The second mode 1520 may be associated with the state of the pool pump 900 immediately after the operator presses the release button 908. The second mode 1520 may be associated with both the first seal 916 and the second seal 918 being disengaged, allowing gas to flow out through the exhaust mechanism through at least one exhaust hole 932 to the external environment. In the second mode 1520, the release top cover 908, the plug 924, the first seal 916, and the second seal 918 may be lowered relative to their respective positions in the first mode 1510. Additionally, in the second mode 1520, the spring 914 may be substantially compressed relative to its configuration in the first mode 1510. In some embodiments, the position of the pump top cover 936 is relatively unchanged between the first mode 1510 and the second mode 1520.

[0094] Figure 15C The third mode 1530 is depicted. The third mode 1530 may be associated with the state of the pool pump 900 immediately after the operator releases the release top cover 908. In some embodiments, the operator may release the release top cover 908 after observing water flowing out through at least one exhaust hole 932 to the external environment. Once the release top cover 908 is released, the second seal 918 rises to an engaged state to seal the gap between the second seal 918 and the pump top cover 936. In some embodiments, the third mode 1530 may be related to the spring 914 being in a stretched or uncompressed state. In the third mode 1530, the first seal 916 may be in a substantially disengaged state, where at least one exhaust hole 932 is not sealed.

[0095] Figure 15DDepicts a fourth mode 1540. The fourth mode 1540 may be associated with the state of the pool pump after establishing a suction pressure. The suction pressure may be established due to a blockage of the inlet (e.g., the inlet 906 in Figures 9 - 10 ), a bend in the hose supplying fluid to the inlet 906 (e.g., the inlet 906 in Figures 9 - 10 ), or any other suction pressure that causes the vent plug to be sucked downward. The fourth mode 1540 may be associated with the first seal 916 contacting the upper surface of the pump top cover 936 to seal at least one vent hole 932 to prevent air and dust from being sucked into the pool pump 900.

[0096] Figures 16A - 16C Shows a cross-sectional view of a pool pump in different modes of discharging exhaust from the pool pump according to some embodiments of the present disclosure.

[0097] The pool pump 1600 may include a manual reset scheme. The manual reset scheme allows an operator to rotate a knob a predetermined amount to discharge gas from the pool pump 1600. Figure 16A Depicts the pool pump 1600 in a closed configuration, where the seal 1630 seals one or more vent holes by pressing against the lower surface of the body 1650. The lower surface of the body 1650 may be configured to have dimples, protrusions, ribs, or a combination thereof to improve the seal. As Figure 16B shown, the operator can rotate the knob 1610 a predetermined amount to lower the plug 1640, thereby disengaging the seal 1630, which allows gas to flow through the one or more vent holes. Compared with the position of the knob 1610 in Figure 16A , the knob 1610 in Figure 16B may be substantially in the same vertical position. As Figure 16C shown, the knob 1610 can be rotated a predetermined amount in the opposite direction to seal the one or more vent holes. In some embodiments, the predetermined amount may be 90° or 180° in the clockwise or counterclockwise direction.

[0098] The screw mechanism 1620 may include a flange portion configured to limit the amount of rotation when the one or more vent holes are closed in the manual reset scheme. In addition, the screw mechanism 1620 may include a screw configured to limit the amount of rotation when the one or more vent holes are opened in the manual reset scheme. Specifically, when the head of the screw contacts a stepped portion on the inner surface of the handle of the knob 1610, the knob 1610 cannot be further rotated.

[0099] Figure 17 Shows a knob and a vent plug of a pool pump according to some embodiments of the present disclosure. Certain features of the pool pump 1600 may be shown in Figure 17 but are not necessarily discussed herein, to the extent that they are the same as those in FIG. 16.

[0100] As described above, Figure 17 the first mode shown on the left side may be associated with the configuration when the pool pump is in a closed configuration. Figure 17 The second mode shown on the right side shows that when the knob 1610 and the screw mechanism 1620 rotate, the exhaust plug 1640 moves vertically to the open configuration, thereby allowing the pool pump 1600 to discharge gas through one or more exhaust holes.

[0101] Figure 18 A perspective view of the knob and the exhaust plug of the pool pump according to some embodiments of the present disclosure is shown. Certain features of the pool pump 1600 may be shown in Figure 18 but not necessarily discussed herein, to the extent that they are the same as those in FIG. 16.

[0102] The knob 1610 may be connected to the screw mechanism 1620 by a snap mechanism or a threaded connection. The screw mechanism 1620 may be configured to have at least one rod, which is configured to convert the rotational movement of the knob 1610 into the vertical movement of the exhaust plug 1640. In certain embodiments, at least one rod of the screw mechanism 1620 may be configured to rotatably engage the threaded inner surface of the exhaust plug 1640.

[0103] In some embodiments, any component of the pool pump 100, the pool pump 900, or the pool pump 1600 may be replaced or supplemented with components of any other pool pump in the present disclosure.
