Description

Technical Field

[0001] The present invention relates to a working machine having a machine room and a housing, wherein the housing at least partially surrounds the machine room or may at least partially surround the machine room. Background Technology

[0002] It is known from the prior art that working machinery has a machine room from which substances or gases are drawn out via pipes.

[0003] Pipelines are drawn out of the machine room, and substances or gases are drawn out into the environment from the open ends of the pipes or from the openings.

[0004] The integration of piping guides and ports into working machinery is often accessed from the outside, making the piping or ports susceptible to damage or impairment in their function. Summary of the Invention

[0005] In this context, the objective of the present invention is to provide an improved integration of piping in working machinery.

[0006] The objective is achieved by a working machine having a machine room and a housing, wherein the housing at least partially surrounds or is capable of at least partially surrounding the machine room, wherein an exhaust chamber is provided in the housing, and a pipe outlet terminates in the exhaust chamber, wherein the exhaust chamber faces the machine room boundary, preferably an airtight boundary, and wherein the exhaust chamber is formed by a sub-region of the housing and a bottom member disposed in the machine room. Advantageous improvements of the invention are the subject of the following description.

[0007] Therefore, according to the present invention, an exhaust chamber is provided at the housing, and the pipe outlet of the pipeline terminates in the exhaust chamber, wherein the exhaust chamber faces the machine room boundary, preferably an airtight boundary, and wherein the exhaust chamber is formed by a sub-region of the housing and a bottom component provided in the machine room.

[0008] Therefore, the term "machine room" should preferably be understood to refer to the classic engine room, fuel system mounting location and / or housing mounting location, or any other component mounting location, such as the mounting location of a fan drive unit. The machine room may contain an ignition source.

[0009] It is conceivable that the bottom component is installed in a way that is fixed to the machine.

[0010] Preferably, the exhaust chamber is located on the side of the machine room.

[0011] A pipe opening can also be called a pipe fitting. A pipe opening can also include a part of a pipe. A pipe opening can also be connected to a pipe, preferably screwed onto the pipe.

[0012] The substances and / or gases in the exhaust chamber should preferably not enter the machine room, but should be led out to the environment of the working machinery.

[0013] Preferably, the sub-region includes a component housed within the housing, preferably a box. Thereby, the component is preferably included within the housing and is an integral part of the housing.

[0014] Preferably, the sub-region or exhaust chamber does not protrude outward from the shell. The sub-region is preferably a recess in the shell, similar to a loggia.

[0015] In an advantageous embodiment, the housing includes an opening connected to or connectable to an exhaust chamber, said opening being covered by a grid or perforated plate disposed at or within the housing. Substances or gases can preferably escape from the exhaust chamber into the environment through the opening. Alternatively, the exhaust chamber may have an opening through which gas can flow outwards. The opening of the exhaust chamber may also be an opening in the housing.

[0016] It is conceivable that the pipeline is a venting pipeline, a hydrogen overpressure pipeline, or an exhaust pipeline, and / or the pipeline opening has a protective cover.

[0017] It is conceivable that the pipe openings are installed or secured to the bottom component.

[0018] Pipelines or pipe openings are preferably elegantly positioned within the silhouette of the working machinery and are preferably implemented in accordance with guidelines.

[0019] Covering the opening preferably ensures that the protective cover to be forcibly installed on the pipe opening will not be lost due to damage.

[0020] Preferably, a seal is provided at the bottom component and / or housing, the seal being capable of creating a clearance, preferably an airtight clearance, between the exhaust chamber and the machine room.

[0021] The housing or sub-regions of the housing and the bottom component can preferably work together with the seals to create an airtight exhaust chamber toward the machine room.

[0022] The seal between the bottom component and the housing is achieved, for example, via a rubber seal, which can also compensate for varying gap dimensions between the component fixed to the machine compartment and the housing.

[0023] It is also conceivable that the housing can be lifted or flipped open, and / or that the housing is a cover or shield.

[0024] Therefore, it is preferable to propose that, in the case of a closed housing, the box or bracket that moves with the housing, cover or shield, together with the bottom component, seals towards the machine room, so that substances or gases discharged from the pipeline, such as hydrogen, are discharged through the grid or perforated plate added to the housing and do not enter the machine room, thereby preventing the ignition of substances or gases in the machine room.

[0025] Preferably, the exhaust chamber allows the protective cover to be ejected or detached from the pipe opening.

[0026] The implementation of the sub-area, box, or exhaust chamber preferably allows the protective cover to be popped open in the event of increased pressure in the pipeline.

[0027] It is also conceivable that water present in or entering the exhaust chamber can flow out through the bottom component.

[0028] It may be proposed that the housing has sheet metal and / or plastic and / or plastic composite materials and / or a combination of materials.

[0029] Preferably, the working machinery includes a fuel cell drive unit and / or a hydrogen reciprocating engine and / or a fuel system, especially a hydrogen fuel system, for fuel that is at least partially in the gaseous state, and / or the working machinery is a mobile working machinery.

[0030] Preferably, the working machinery has a hydrogen fuel system, and a fuel cell drive or a hydrogen reciprocating engine is fed by means of the hydrogen fuel system.

[0031] Furthermore, the fuel in the fuel system can involve any conceivable gaseous fuel, such as hydrogen, natural gas, or methane gas.

[0032] In the fuel system, it is desirable that vent lines and overpressure lines be routed from the machine room at appropriate locations.

[0033] Preferably, the working machinery relates to wheel loaders, telescopic loaders, excavators with wheeled and / or tracked travel mechanisms, articulated dump trucks, bulldozers and / or tracked loaders, or machines in the field of material handling technology.

[0034] Preferably, it is feasible to discharge the pipeline, hydrogen overpressure pipeline, or exhaust pipeline to the environment in accordance with the guidelines.

[0035] The present invention preferably addresses the requirements of automotive hydrogen standards in a manner that is both highly effective and elegant.

[0036] It should be noted that the terms "a" and "an" do not necessarily refer to exactly one of the elements, although this indicates a feasible embodiment, but can also refer to multiple elements. Similarly, the use of the plural includes the presence of the elements in the singular, and vice versa, the singular also includes multiple elements in the plural. Furthermore, all features of the invention described herein can be claimed in any combination or in isolation. Attached Figure Description
