Definitions
- the present invention relates to a novel floor nozzle for hard floors.
- an attachable to a vacuum cleaner attachment which consists of a suction tube, a connectable with this mouthpiece and a suction tube arranged on the container for cleaning liquid, which accessory in Mund Nursinggeophuse a liquid-conducting connected to the container distribution strip and one of these , movably mounted applicator body is provided. Due to the arrangement of the container for cleaning liquid to the suction pipe of the vacuum cleaner working is cumbersome and a dosage of the correct amount of liquid is not possible.
- the present invention seeks to provide a comparison with the prior art improved arrangement with a dosage of the liquid in response to the operation of the floor nozzle.
- a floor nozzle for hard floors which has a liquid supply means for a wiper and a control means which is adapted to allow and prevent the delivery of liquid to the wiper.
- the control means is adapted to allow and prevent the delivery of liquid in response to the operation of the floor nozzle.
- the conveyed liquid quantity to the wiping means can be controlled via the control means.
- a delivery of liquid with maximum amount is permitted and, outside the operation of the floor nozzle, a delivery of liquid is completely prevented.
- control means which allows, for example, the promotion of only a small amount at a slow processing or, for example, allows the promotion of a larger amount of liquid when the floor nozzle is operated in the suction operation with high negative pressure.
- the control in its basic position, the promotion of liquid preventing control means for allowing the delivery of liquid during the operation of the suction may be formed.
- the control means for allowing and preventing the delivery of liquid in response to a voltage applied during the work of suction negative pressure is formed.
- the control means may be a valve for opening and closing a supply line of the liquid supply device.
- the valve may be a switching valve that can be switched between an open position and a closed position.
- the valve is preferably arranged in a supply line of the liquid supply device which connects a liquid tank and a pump. As a result, the delivery of liquid can take place in a line section which is still in front of the pump. As a result, the control means is closed in a line section which is not yet under a pressure generated by the pump. This ensures the effectiveness of closing the valve.
- the valve may have a slide which can be positioned from a position closing the supply line to a position opening the supply line as a function of the position of a control device diaphragm which can be adjusted by means of a vacuum. If a vacuum is applied to the floor nozzle, ie the floor nozzle is in operation, the valve is opened due to the negative pressure. The valve is opened by pulling the slide out of the supply line. If the floor nozzle is not in operation, no negative pressure is generated. If there is no negative pressure on the floor nozzle, then the valve closes and the slide goes into a position in which he closes the supply line. Then a promotion of liquid is prevented.
- the valve may have a housing box which is airtightly divided by the control diaphragm into a first control means chamber and a second control means chamber, wherein the first control means chamber connected via an opening to a negative pressure suction port and the second control means chamber to a slider having portion of the supply line is.
- the valve to prevent overstretching of the control diaphragm beyond its maximum strain position on support means by which the control diaphragm is retained in its maximum expansion position. If a very high negative pressure is applied to the floor nozzle, then the control diaphragm is deflected maximally. So that the control diaphragm does not stretch beyond its permissible maximum position, support means are provided which prevent overstretching of the control diaphragm. The support means forms a stop on which the control diaphragm is present in its maximum deflection.
- the support means may be a grid covering the opening of the first control means chamber. Through the openings of the grid it is ensured that furthermore the full vacuum can be present at the control diaphragm and thus the control function is ensured unhindered.
- the web portions of the grid a support structure which is able to support the control medium membrane almost the entire surface, so that the control medium membrane is tension-free supported in its maximum deflection.
- control means is integrated in the floor nozzle and connected to detect a negative pressure to a suction channel of the floor nozzle.
- the figures show exemplary details of a hard floor nozzle according to the invention, namely a safety valve arranged on the nozzle.
- a tank On the nozzle, a tank is attached, which can be removed for filling of the nozzle. From this tank a line leads to the safety valve and then on to the pump with the help of which the water is transported to the cloth.
- the safety valve is preferably closed as long as the nipple is not switched on. This means that as long as there is no negative pressure at the nozzle, the valve does not open and releases no liquid.
- the valve is preferably arranged on the suction channel and consists of a silicone membrane and a T-tube. There is now negative pressure at the nozzle. the diaphragm moves towards the suction channel and releases the pipe via a plunger.
- the membrane is supported, for example via a protective grid, so that overstretching is prevented.
- the valve works in the following way: By switching on the vacuum cleaner, a negative pressure is generated. As a result, the membrane is pulled down, towards the support grid and thus opens the connection of the inlet and outlet channel. This allows the fluid to flow from the tank to the pump. When the device is switched off, the membrane closes the two channels, no liquid medium can flow.

- the valve housing 137 itself is designed dome-shaped. Inside the valve housing 137, the slider 138 is arranged.
- the slide 138 has a finger-like shape, which is adapted to the inner cavity of the valve housing 137 such that a liquid-tight but displaceable mounting of the slider 138 is ensured in the valve housing 137.
- the tip of the finger-shaped slider 138 rests in the arch 148 of the valve housing 137 and seals the two valve ports 147a and 147b so that no liquid from the first portion 104a of the conduit 104 into the second portion 104b the supply line 104 can get.
- the slider 138 is integrally formed on a control diaphragm 139.
- Slider 138 and control diaphragm 139 are made of an elastic plastic, in particular of an elastomer, silicone rubber or TPE.
- the control diaphragm 139 is substantially circular disk-shaped and in its relaxed position assumes the position shown in FIG. 7, in which the slider 138 is in a closed position of the valve 136 in which a liquid passage from the first portion 104a of the supply line 104 in the second portion 104 b of the supply line 104 is prevented.
- the control diaphragm 139 divides the housing box 140 into a first control central chamber 141 and a second control central chamber 142.
- the first control chamber 141 is shown in FIG.
- the second control central chamber 142 is shown in FIG. 7 above the control diaphragm 139.
- the second control central chamber 142 is liquid-tight isolated and empty.
- the first control means chamber 141 has an opening 143, via which a connection to the suction channel 21 is provided. If a negative pressure now prevails in the suction channel 21, this negative pressure will continue via the opening 143 into the first control-medium chamber 141.
- the first tax Determining chamber 141 has no other openings, so that the negative pressure can not be lost. Due to the negative pressure in the first control means chamber 141, the control diaphragm 139 is now deflected down to counteract the negative pressure.
- control diaphragm 139 With the deflection of the control diaphragm 139 down the integrally formed on the control diaphragm 139 slide 138 is also moved downward. In a lower position of the slide 138, the connection in the valve housing 137 is exposed and liquid can pass from the first portion 104a of the supply line 104 via the valve connection piece 147a into the second portion 104b of the supply line 104 via the valve connection piece 147b. A transport of liquid from the liquid tank 1 1 to the wiper 5 is now possible.
- control diaphragm 139 In the open position of the slider 138, the control diaphragm 139 is deflected maximum downward. In this deflection, the space of the second control central chamber 142 is extended, without a medium can flow. Consequently, a negative pressure is generated in the second control central chamber 142, which forces a return movement of the control diaphragm 139 as soon as there is no negative pressure in the suction channel 21 or in the first control central chamber 141.
- the control diaphragm 139 is moved due to the negative pressure in the second control means chamber 142 upwards to its normal position and the integrally formed on the control diaphragm 139 slide 138 resumes its the supply line 104 occluding position.
- a grid 144 is inserted in the opening 143.
- the grid 144 has sufficiently large passages, so that the negative pressure from the suction channel 21 can be carried away lossless in the first control means chamber 141.
- the grid 144 is rigidly held in the housing box 140.
- the control-agent diaphragm 139 is deflected maximally downwards until it rests against the upper side of the grille 144.
- the grid 144 prevents deflection of the control diaphragm 139 beyond its maximum allowable deflection position.
