Abstract
ABSTRACT OF THE DISCLOSURE
A hot water and vacuum cleaning apparatus comprises a hot water generating unit and a vacuum generating unit each having a tank and means for apply-ing steam and vacuum from these units to a hand tool. The hot water and vacuum generating units are mounted on a single trolley with their tanks located within the confines of a rigid frame of which the lower part confines the pumps and pump driving means of the units. The vacuum generating unit tank is mounted in the frame above the level of the pumps and pump driving means, whereas the hot-water generating unit tank is located beside the vacuum generating unit tank and extends downwardly beyond it within the lower part of the frame. This relative position-ing of the components of the apparatus enables the latter to be light and compact with all components readily accessible for purposes of operation and maintenance.

Description
This invention relates to hot water and vacuum cleaning apparatus of the general kind disclosed in U.S.A. Patent Specification 3,262,146 and our British Patent Specification 1,286,985 and which comprises a hot water generating unit and a vacuum generating unit, each having a tank, and means for applying hot water and vacuum from these units to a hand tool.
The main object of the invention is to provide hot water and vacuum cleaning apparatus of this kind which is more compact and lighter and easier to use than its predecessors.
In accordance with the invention therefore, a hot water and vacuum cleaning apparatus of the kind referred to is characterised in that the hot water and vacuum generating units are mounted on a single trolley with their tanks within the confines of a rigid frame of which the lower part confines the pumps and pump driving means of the units, the vacuum generating unit tank being mounted in the frame at a level above the said pumps and pump driving means, whereas the hot water generating unit tank is located beside the vacuum generating unit tank and extends downwardly beyond it within the lower part of the frame.
A preferred embodiment of the present invention hereinafter to be described is illustrated by way of example in the accompanying drawings, in which:
Figure 1 is a front elevation of hot water and vacuum cleaning apparatus with front panels mainly removed;
Figure 2 is a side elevation of the apparatus . .
' ' ' . ' ' . ~
with side panels mainly removed; and Figure 3 is a plan view.
Referring now to the drawing there is shown a trolley comprising a rectangular light alloy frame 1 within which the vacuum and hot water generating units are mounted and which is supported on a pair of large diameter fixed aspeci wheels 29 and a pair of swivel castors 30. The frame 1 is covered with section-al panels 8 made of synthetic plastics material which are detachable to permit access to the apparatus components for maintenance purposes and also has a top cover 20.
Within the confines of the frame 1 there is the hot water generating unit which comprises a rectangular water tank

Referring now to the drawing there is shown a trolley comprising a rectangular light alloy frame 1 within which the vacuum and hot water generating units are mounted and which is supported on a pair of large diameter fixed aspeci wheels 29 and a pair of swivel castors 30. The frame 1 is covered with section-al panels 8 made of synthetic plastics material which are detachable to permit access to the apparatus components for maintenance purposes and also has a top cover 20.
Within the confines of the frame 1 there is the hot water generating unit which comprises a rectangular water tank
2 extending downwards to the bottom of the frame 1. This tank is of welded lightweight construction - since only a very low vapour pressure is generated - and fitted with an electric immersion heater 6 protected by a fuse 19 and controlled by an independent switch 15 having an integral indicator lamp and a thermostat 7 in the circuit which prevents the water temperature exceeding 80C. The latter can be set to a lower temperature if required. The heater 6 also incorporates a cut-out for additional protection. The tank 2 also incorporates a level control module 33 which is designed to cut off the power supply to a pressure pump motor - hereinafter referred - ~ - . .

to - at a predetermined minimum wate~ level.
The ta~k 2 is connected by a feed pipe 31 to the inlet of a centrifuge pressure pump 22 which is combined with a single high speed driving motor controlled by an independent switch 1G with an integral indicator lamp and protected by another fuse 19. ~la pressure p~Tp is also connected to a separate direct inlet pipe 35 which is independent of the water tan~ 2 and intended to permit special cleaning fluids to be introduced when required without their having to be placed in the water tank 2.
The pump has an outlet pipe 27 which is adapted to accept one end of a detachable flexible hose of which the other end would be connected to a control valve on one of various di~ferent hand tools which are used remote from the cleaning apparatus. Parallel with the outlet pipe 27, and below the centre line of the pump 22, there is a small drain cock 28 to enable the pump to be completely drained of water in sub-zero temperatures and thereby avoid damage otherwise caused by water freezing. Also the outlet pipe 27 has an air lock chamber 26 to enable a constant pressure to be maintained in the outlet pipe 27. A temperature gauge 10 and a pressure gauge 11 are i B incorporated in the ~o~m generation system ~ld are situated on a control panel 9 attached within the top part of the frame 1, this co~trol panel also serving to mount the switches 15, 16 and the fuses 19 which have already been mentioned.

part of the light alloy ~rame 1 there is mounted a cylindrical vacullm tank 3 ~hich is specially designed and manufactured to with.stand vacuum pu1sations or consequent creep fatigue. It has a greater capacity than the water ta~ 2 -to permit complete usage o~ a ~ull water tan~
without the risk of overfi].ling the vacuum tank wi.th collected dirt and liquid. The vacuum tank 3 has a detachable transparent moulded acrylic material dome 4 which is secured to the tank and sealed therewith by a neoprene gasket. The tank 3 incorporates a vacuum relief : valve 5, a liquid level control module 33 which breaks an.electric circuit to a vacuvm pump motor at a predeter-mined level and so prevents soiled liquid and foam being drawin into the vacuum pump, and a wide aperture drain cock 34 for rapid drainage when desired.
me vacuum tank is connected to a combined motor and ,pump 21 located within the lower part of the frame 1 by a suction pipe 24. The motor and pump 21 is controlled by a .i circuit breaker 17 and is secured to the base of the trolley by means o~ three vibration damped mounting pillars (not shown). The motor and pump control circuit incorporates an indicator lamp 18 on the control panel 9.
: Also mounted on the control panel 9 is a digital timer : 13, which enables an accurate record of cleaning time to be kept, a vacuum gauge 12 and a mains connection plug 14.
Also shown in,the drawings and not hitherto mentioned are an inlet pipe 23 to the vacuum tank 3, a cooling air inlet 25 to the vacuum tank, the vacuum pump exhaust pipe .

It is also a feature of the apparatus described that when empty it is of sufficiently light weight for lifting by one person.
