State of the art
[0001] Sanitary appliances fitted with grinding devices and water-pumping systems are increasingly
widespread, which devices, however, are generally installed behind the sanitary appliances
inside a generally rectangular-shaped case.
[0002] The simpler models feature operating mechanisms that are integral with the waste
pipe and, as rule, it is necessary to remove the sanitary appliance before cleaning,
unclogging or performing any other maintenance operation on it, by disconnecting the
waste pipes and connections with the other appliances; this operation may be carried
out only by a plumber and is expensive and time-consuming.
[0003] In the more recent and expensive models, the device is made up of two units:
a fixed unit housing the container collecting the waste water from the sanitary appliances,
and
a removable unit containing the pumping, grinding and control systems.
Description of the invention
[0004] The above mentioned version unquestionably speeds up maintenance operations and reduces
the cost of the grinding device/pump, but it does not solve the problem of its poor
design and unappealing appearance and hardly fits in with the sanitary appliances.
[0005] This invention relates to a grinding device and pump, and related systems, which
are housed inside a unit installed beneath the toilet bowl; the unit is designed and
shaped so as to fit in harmoniously with the sanitary appliance, it is well-designed
and pleasant to look at.
[0006] The invention also provides for a quick-fit system for connecting the device to both
the appliance and the waste pipes.
[0007] The contact surface between the unit and the upper edge of the appliance is fitted
with a guiding device, or similar means, for properly installing the unit and fastening
it to the appliance.
[0008] Other means for fastening the unit to the appliance are provided at the back of the
unit and may consist, for example, of threaded screws for securing the unit to the
appliance or brackets or supports integral therewith.
Description of the Drawings
[0009] A specific embodiment of the invention will now be described by way of example with
reference to the accompanying drawings, in which:
Figure 1 shows an axonometric view, from below, of the appliance fitted with the invention.
Figure 2 shows a cross-section from the side of the appliance fitted with the invention.
Figure 3 shows a cross-section from the front of the appliance fitted with the invention.
Detailed description of the preferred embodiment
[0010] Referring to the above mentioned drawings the sanitary appliance (1) is fitted at
the bottom with a unit (2) housing the set of mechanical / hydraulic / electrical
systems (3), which include,
inter alia, the pump, grinding device, pressure switch and the other devices for operating the
assembly.
[0011] The waste inlet and outlet pipes - which may be of any diameter - can be quickly
and easily connected and disconnected for speedy maintenance of the grinding device.
[0012] The unit (2) is shaped so as to fit in harmoniously underneath the sanitary appliance
(1) and to cover and contain the entire device assembly (3).
[0013] For rapidly installing the unit (2) in its position underneath the sanitary appliance
(1), holes are provided (3) and (4) for the fastening devices of the unit (2) to the
sanitary appliance (1); such fastening devices may be either screws or bayonet catches,
or other known means, such as an expansion lock.
[0014] Along the contact surface between the unit (2) and the sanitary appliance (1), preferably
at the front, another fastening means (5) has been provided for securing the front
of the unit (2) and also for properly positioning the unit (2) to the sanitary appliance
(1).
[0015] As previously mentioned, the shape and size of the unit (2) varies according to the
shape of the sanitary appliance, so as to constitute a harmonious whole that does
not reveal the presence of a grinding device/pump underneath the appliance.
[0016] The material and colour scheme too are such as to render the unit/appliance assembly
as uniform as possible.
1. Improvements to a grinding device and pump for sanitary appliances wherein the electrical,
hydraulic and mechanical systems and assemblies (3) operating the grinding device
and pump are housed inside a unit (2) installed underneath the appliance (1), which
unit (2) is shaped in such a manner as to fit in harmoniously with the appliance (1)
and is provided with suitable means for fastening thereto.
2. Improvements to a grinding device and pump for sanitary appliances as claimed in Claim
1 wherein the unit (2) features fastening means (4), at the back, which may be screws,
etc., for securing the unit (2) to the appliance (1).
3. Improvements to a grinding device and pump for sanitary appliances as claimed in the
preceding Claims wherein the waste water inlet pipe to the grinding device and outlet
pipe from the device to the drain pipe are of the quick-fit type, for a speedy connection
or disconnection.
4. Improvements to a grinding device and pump for sanitary appliances as claimed in the
preceding Claims wherein fastening devices (5) are provided along the contact surface
between the unit (2) and the appliance (1), for properly fitting the unit (2) and
securing it to the appliance (1).
