- water can be pressurized by means of a pump and heated by means of a heatable heat exchanger.
- the heated and pressurized water can be directed at an object to be cleaned.
- the heat exchanger is usually operated with the aid of a liquid fuel, for example heating oil or diesel fuel, and can have a coiled tube which is heated by a burner and through which the water is passed.
- the liquid fuel for operating the heat exchanger is stored in a fuel tank.
- heatable high-pressure cleaning devices are known, for example, from WO 2012/119641 A2.

- the support frame completely surrounds the fuel tank in the circumferential direction. It is particularly favorable if the supporting frame forms the chassis of the heatable high-pressure cleaning device. At least two wheels are preferably mounted on the chassis so as to be rotatable about a common axis of rotation.
- At least one swivel castor is also advantageously rotatably mounted on the chassis.
- the support frame projects beyond a front and a rear of the fuel tank in relation to a main direction of movement of the high-pressure cleaning device.

- the motor can cover the through shaft, the through shaft allowing air to circulate which surrounds the motor and dissipates heat from the motor.
- the high-pressure cleaning device can, for example, be connected to a public water supply network.
- a public water supply network With such a connection to a public water supply network, the network operator often makes the requirement to take suitable measures to ensure that water taken from the water supply network cannot be inadvertently returned to the water supply network. This is to ensure that the water supply network does not come into contact with potentially contaminated water.
- the high-pressure cleaning device according to the invention in a preferred embodiment has a decoupling tank with an inlet that can be connected to a water supply network and with an outlet that is in flow connection with the pump.

- the recess can be configured, for example, in the form of a pocket.
- a level-dependent valve for example a float valve, is preferably arranged at the inlet of the decoupling tank. Using the level-dependent valve, it can be ensured in a structurally simple manner that the decoupling tank does not overflow. Rather, the level-dependent valve closes and breaks the connection from the water supply network to the decoupling tank when the level of the decoupling tank reaches a maximum level.
- a liquid cleaning agent is added to the water, which is stored in a cleaning agent tank.
- the fuel tank of the heatable high-pressure cleaning device advantageously forms a multifunctional part which, on the one hand, serves to store liquid fuel and, on the other hand, gives the high-pressure cleaning device considerable mechanical stability, and which also forms the lower housing part, which holds the motor and the pump and preferably also receives a fan driven by the motor, air being able to be supplied to the heat exchanger by means of the fan.

- the fuel tank is conveniently made by rotational molding. This manufacturing process enables a particularly robust design of the fuel tank.
- the fuel tank produced by rotational molding can be manufactured in a single step. Impact-resistant plastics can be used here, so that a mechanically particularly resilient fuel tank can be produced.
- the heatable high-pressure cleaning device in addition to a lower housing part which is formed by the fuel tank, the heatable high-pressure cleaning device according to the invention, in an advantageous embodiment, has an upper housing part which is arranged on the lower housing part.
- the upper housing part can be designed, for example, in the form of a hood, which covers the lower housing part.
- the upper housing part is advantageously designed as a one-piece, in particular closed, hollow plastic body. This gives the upper housing part a high mechanical strength.

It is advantageous if the upper housing part has a through channel which extends from an upper side of the upper housing part to an underside of the upper housing part, the hanging frame part of the support frame being accessible to the user via the through channel. With such an embodiment of the invention, the user has the possibility, for example, of passing a crane hook or a lifting belt through the through-channel of the upper housing part in order to fix the crane hook or the lifting belt on the hanging frame part of the supporting frame. This simplifies the handling of the high-pressure cleaning device when it is transported by means of a lifting device.
- the upper housing part forms at least one hook for winding up a hose and / or an electrical cable.
- a pressure hose and / or an electrical supply cable can be wound on a hook formed by the upper part of the housing.

- the support frame 110 also has a rigid hook-in frame part 156, via which the first side frame part 116 is rigidly connected to the second side frame part 120 on its upper side facing away from the base frame part 136.
- the hanging frame part 156 overlaps the fuel tank 32, extending transversely to the main direction of movement 26. It has one first support frame suspension section 158 and a second support frame suspension section 160, which are aligned at an obtuse angle to one another and are integrally connected to one another.
- a crane hook which is not shown in the drawing for a better overview, can grip around the mounting frame part 156 in order to lift the complete high-pressure cleaning device 10.
- a first rigid rear frame part 162 which is designed in the form of a bow, extends from a rear side of the first side frame part 116 facing away from the front frame part 132 to the first support frame hanging section 158 and forms a first handle 164 of the high-pressure cleaning device 10.
- a second rigid rear frame part 166 which is also designed in a bow-shaped manner, extends from a rear side of the second side frame part 120 facing away from the front frame part 132 to the second support frame hanging section 160 and forms a second handle 168 of the high-pressure cleaning device 10.
- the two rear frame parts 162, 166 protrude from the rear 114 of the fuel tank 32 and also from the rear of the heat exchanger 28, counter to the main direction of movement 26.
- the support frame 110 forms a shock protection, which ensures that the fuel tank 32 is not damaged in the event of an unintentional impact with an obstacle.
- the lower housing part 12 formed by the fuel tank 32 is the
- the upper housing part 14 is designed as a one-piece, closed hollow plastic body and is produced by rotational molding. It has a through-channel 170, which extends from an upper side 172 of the upper housing part 14 to a lower side 174 of the upper housing part 14 and in one of the front side 36 of the fuel tank 32 is passed through by an exhaust pipe 176 facing away from the rear region, via which the exhaust gases of the heat exchanger 28 can be released.
- the through-channel 170 forms an access to the hanging frame part 156.
- the upper housing part 14 In the main direction of movement 26 at a distance from the through-channel 170, the upper housing part 14 has an essentially rectangular opening 178, on which an operating panel 180 is arranged, which has a main switch 182 on its upper side for switching the electric motor 76 on and off.
- the upper housing part 14 On its rear side 184, the upper housing part 14 forms a winding hook 186 onto which, for example, a pressure hose and / or an electrical cable can be wound.
- the winding hook 186 is arranged between the first handle 164 and the second handle 168.
- the high-pressure cleaning device 10 is distinguished by low manufacturing costs and high mechanical stability. Both the lower housing part 12 and the upper housing part 14 are produced by rotational molding and form one-piece, seamless plastic hollow bodies.
- the lower housing part 12 is formed by the fuel tank 32, which is carried by the support frame 110 and which not only forms the chassis 24 of the high-pressure cleaning device 10 but also a shock protection device which, when the high-pressure cleaning device 10 strikes an obstacle, damages the fuel tank 32 prevented.
