WALL-INSTALLABLE MACERATOR PUMP

Abstract

A wall-installable macerator pump includes a tank, which is configured to house a macerating assembly. The width of the tank is configured to be positionable inside a cavity defined inside a wall. The macerating assembly comprises a motor, a pump cavity, and a chopper pump positioned inside the pump cavity. The motor receives sewage material through a sewage inlet, and sullage material through a sullage inlet, where the sewage inlet and the sullage inlet are positioned on the tank. The pump cavity receives the sewage material and sullage material, and a combination of the sewage material and sullage material defines a combined waste. The chopper pump positioned inside the pump cavity macerates and pumps the combined waste through a discharge outlet positioned on the tank.

DETAILED DESCRIPTION OF THE INVENTION

[0018] Referring to FIGS. 1A-1C, FIG. 1A exemplarily illustrates a top perspective schematic view of the wall-installable macerator pump 100, FIG. 1B exemplarily illustrates a front perspective schematic view of the wall-installable macerator pump 100, and FIG. 1C exemplarily illustrates a side perspective schematic view of the wall-installable macerator pump 100. The wall-installable macerator pump 100 generally has a tank 101, which is configured to house the corresponding pumping components. The pumping components housed within the tank 101 comprise the motor 103, the pump cavity 106, and the chopper pump (not shown). The wall-installable macerator pump 100 is designed to be positioned inside a wall 200, for example, drywall 200, which would be further described in the following sections. Other plumbing components comprise a sewage inlet 104, a sullage inlet 105, a discharge outlet 107, and a vent outlet 108 which convey inflow and outflow of waste matter. These components are designed so that they access the wall-installable macerator pump 100 through the drywall 200 in which the wall-installable macerator pump 100 is secured or positioned. This is achieved with the help of multiple openings in the drywall 200, which are aligned with the respective sewage inlet 104, sullage inlet 105, discharge outlet 107, and vent outlet 108.

[0019] Referring to FIGS. 2A-2C, FIG. 2A exemplarily illustrates a top perspective schematic view of the wall-installable macerator pump 100 positioned inside the wall 200, FIG. 2B exemplarily illustrates a front perspective schematic view of the wall-installable macerator pump 100 positioned inside the wall 200, and FIG. 2C exemplarily illustrates a side perspective schematic view of the wall-installable macerator pump 100 positioned inside the wall 200. The wall-installable macerator pump 100 comprises a tank 101, which is configured to house a macerating assembly 102. The width of the tank 101 is configured to be positionable inside a cavity defined on a wall 200, so that the positioning of the wall-installable macerator pump 100 retains available space inside the wall. In conventional systems, the macerating units are generally positioned close to the toilet bowl 201 or attached behind the toilet bowl 201. Therefore, since the wall-installable macerator pump 100 is inserted and installed inside the wall 200 by creating a space inside the wall 200, the effective utility space or the available space for a user to move around the toilet is unaffected. Therefore, this arrangement makes it comfortable for the users who desire more space inside the toilet room.

[0020] The wall-installable macerator pump 100 comprises the motor 103, the pump cavity 106, and the chopper pump positioned inside the pump cavity 106, as mentioned in FIGS. 1A-1C. The motor 103 receives sewage material through the sewage inlet 104, and sullage material through a sullage inlet 105, where the sewage inlet 104 and the sullage inlet 105 are positioned on the tank 101. As disclosed herein, the term sewage refers to a suspension of water and solid waste, which are collected from the toilet bowl 201 to be disposed of, or processed. The term sullage refers to the liquid discharges from kitchens, washbasins, toilets, etc. The sewage inlet 104 and the sullage inlet 105 are connected to the wall-installable macerator pump 100 through pipe that passes through openings drilled through the wall 200. The sewage material is received at the sewage inlet 104 via a sewage pipe 109, and the sullage material is received at the sullage inlet 105 via a sullage pipe 110, which are coupled to the respective inlets.

[0021] The pump cavity 106 receives the sewage material and the sullage material, and a combination of the sewage material and sullage material defines a combined waste. The pump cavity 106 has a volume to collect the combined waste, which is then allowed to be reduced or grinded to smaller particles in the chopper pump. The grinding of the waste material is to make it pump-able either upwards from a basement location or horizontally to an existing septic or sewage system. The chopper pump positioned inside the pump cavity 106 macerates and pumps the combined waste through the discharge outlet 107 positioned on the tank 101. The chopper pump is generally a centrifugal pump, which includes sharp blades that slice and reduce the solid particles in the sewage material to a smaller size.

[0022] Further, the chopper pump pumps the reduced combined waste through the discharge outlet 107, and the reduced combined waste is collected in a community waste treatment system or a waste collection tank. Therefore, the wall-installable macerator pump 100 is not an essential part of any conventional treatment system, but a suitable method to transfer the waste material to the treatment system. The discharge outlet 107 extends from the tank 101, through the wall 200, and into an existing sewer or septic system. The discharge outlet 107 is connected to a discharge pipe 112 to transfer the combined waste to the septic system. In an embodiment, the wall-installable macerator pump 100 further comprises vent outlet 108 positioned on an upper surface of the tank 101. The vent outlet 108 extends upwardly via a vent pipe 111 through the wall 200 to terminate into the structures pluming a vent system or directly to the outside, and is configured to exhaust odor from the combined waste as shown in FIG. 2B-2C.

[0023] FIG. 3 exemplarily illustrates a front perspective view of the wall-installable macerator pump 100 positioned inside a wall 200 with the access door 113 to perform maintenance on the motor 103. In an embodiment, the wall-installable macerator pump 100 further comprises an access door 113 positioned on the wall 200 proximal to the tank 101. The access door 113 is configured to perform maintenance activities on the wall-installable macerator pump 100. The access door 113 can be constructed on either side of the wall 200 depending on the user's choice. The access door 113 on the wall 200 provides easy access for maintenance workers so that the maintenance workers can open the access door 113 and remove the cap 114 of the motor 103, so that they can fix any problem related to the motor 103.

[0024] The wall-installable macerator pump 100 can be installed behind the wall of the toilet in either direction. The wall-installable macerator pump 100 would be positioned inside the drywall 200 proximal to the toilet; therefore, the bottom of the tank is contoured so that the drywall 200 screws will not penetrate the tank when the drywall 200 is installed. Unused toilet and other inlets can be capped without interfering with the drywall 200. The supplementary inlets and outlets are centered so that they can be plumbed from sufficient distance from the wall 200.
