Description

Technical Field

[0001] This invention relates to the field of energy conversion device technology, specifically a generator set. Background Technology

[0002] A generator, as a complete set of mechanical equipment capable of converting other forms of energy into electrical energy, typically includes a casing and internal working devices, a cooling system, an exhaust system, and a muffler. During operation, the working devices convert other forms of energy into mechanical energy, and then that mechanical energy into electrical energy. During operation, the cooling system provides air to the working devices and, in conjunction with the exhaust system, dissipates heat from the generator set.

[0003] As a power supply device, generator sets have multiple operating buttons or power sockets with different functions on their casings. Therefore, to ensure electrical safety, extra care must be taken to prevent water damage during use, especially in extreme weather conditions such as rain. However, modern generator sets cannot be completely sealed; gaps may exist in the generator set's casing, allowing water to enter. Once water gets inside the generator set, the internal circuitry is prone to short circuits, malfunctions, or even burnout, posing a significant safety hazard and greatly impacting the electrical safety of the generator set during use. Summary of the Invention

[0004] The present invention aims to provide a generator set to solve the electrical safety problems existing in the prior art generator sets.

[0005] The basic solution provided by the present invention is: a generator set, including a housing and a working device located inside the housing, the housing being provided with an air inlet and an air outlet; the working device including an engine with a cooling fan and an air guide shroud surrounding the engine; wherein: the housing includes an inner chamber composed of internal flow channels of the working device and an outer chamber composed of the inner wall of the housing and the outer surface of the working device; the flow channels of the inner chamber are connected to the air inlet and the air outlet; the inner chamber is connected to the outer chamber.

[0006] The beneficial effects of the basic scheme are as follows: In this scheme, the interior of the outer shell is divided into an inner chamber and an outer chamber. After the inner chamber is composed of the internal flow channels of the working device, the air flowing in the internal flow channels of the working device can realize the normal heat dissipation function of the working device, ensuring the normal operation of the working device. After the outer chamber is set, the connection between the inner and outer chambers allows the air flowing in the inner chamber to enter the outer chamber. Since the outer chamber has no other outlet, as the air in the inner chamber gradually enters the outer chamber, the air pressure in the outer chamber gradually increases, presenting a positive pressure state. Under this state, not only can the substances outside the outer shell not enter the interior of the outer shell, but also the air in the outer chamber will continuously blow out the substances in the gaps of the outer shell, which can prevent water from entering the generator set, thus avoiding electrical safety problems caused by water ingress, reducing the safety hazards of the generator set, and also preventing external dust from entering the interior of the outer shell, playing a dustproof role.

[0007] Furthermore, the air guide hood is equipped with an exhaust port that communicates with the outer chamber. Beneficial effect: In this design, the connection between the inner and outer chambers can be achieved simply by utilizing the exhaust port on the air guide hood, resulting in a simple structure.

[0008] Furthermore, the air guide shroud is equipped with an inlet, which is sealed to the air inlet. Beneficial effect: In this design, the sealed connection ensures that all air entering from the air inlet is drawn into the air guide shroud, thereby guaranteeing the heat dissipation effect inside the generator set.

[0009] Furthermore, the inlet and air intake are sealed together using a flexible connector. Beneficial effect: In this design, the flexible connector isolates the inlet from the interior of the casing, thereby ensuring the outer chamber remains in normal working order during generator set operation, thus guaranteeing the generator set's waterproof and dustproof performance.

[0010] Furthermore, an installation cavity for mounting the inverter is provided between the inlet and the air inlet. Beneficial effect: In this design, placing the inverter between the inlet and the air inlet facilitates heat dissipation for the inverter.

[0011] Furthermore, the engine is equipped with a cooling channel, and the air shroud has air intake vents. The outlet of the cooling channel connects to the air outlet. Beneficial effect: In this design, the cooling channel allows air to be introduced into the engine for cooling, ensuring normal engine operation. Furthermore, the outer casing includes a mounting frame and multiple panels. The mounting frame has multiple support beams, and the contact points of adjacent panels abut against the support beams. Beneficial effect: In this design, the mounting frame strengthens the outer casing. Furthermore, since there will inevitably be gaps at the contact points of the panels, the support beams cover these gaps, reducing the probability of external substances entering the casing through these gaps. This further ensures waterproof and dustproof performance. The cover-up of gaps by the support beams also improves the aesthetics of the casing, enhances its sealing, and prevents noise generated by the internal working devices from escaping, thus achieving noise reduction.

[0012] Furthermore, the panel includes a main control panel, on which multiple operating components for controlling the working devices are installed. Beneficial effect: In this solution, by placing the operating components for multiple working devices on the same panel, the operator only needs to be in front of the same panel to complete multiple operations on the working devices, facilitating the operator's control of the generator set.

[0013] Furthermore, a push handle is provided on the mounting frame, positioned on the same side as the main control panel. Beneficial effect: In this design, placing the push handle on the same side as the main control panel further facilitates the operator's control of the engine unit.

[0014] Furthermore, the working device also includes an air filter, a resonant cavity, an oil-gas mixing device, and a muffler. The air inlet is equipped with an air filter inlet. The air filter inlet, air filter, resonant cavity, oil-gas mixing device, engine, and muffler are connected sequentially, and the muffler is connected to the air outlet. Beneficial effects: In this design, the internal chamber of the working device consists of the air filter inlet, air filter, resonant cavity, oil-gas mixing device, engine, muffler, and air outlet. Air enters the air filter through the air filter inlet for filtration, then passes through the resonant cavity, and then sequentially through the oil-gas mixing device and engine to participate in engine combustion. It is then converted into exhaust gas, which is silenced by the muffler and discharged from the air outlet. This ensures normal engine operation and, through the cooperation of the resonant cavity and muffler, achieves noise reduction. Finally, the air required for engine operation is introduced through the air filter, not from the outer chamber, thus ensuring that the outer chamber remains under positive pressure during generator set operation, thereby guaranteeing the generator set's waterproof and dustproof performance.

[0015] Furthermore, the resonant cavity and the air filter are connected via a first flexible component. Beneficial effect: Considering that the engine vibrates during operation, while the air filter, as an air filtration device, does not vibrate, directly connecting the engine and air filter could damage the connection point. Therefore, this solution utilizes a first flexible component to connect the resonant cavity and the air filter, ensuring a stable connection and thus guaranteeing normal engine intake, further ensuring the engine's normal operation.

[0016] Furthermore, the first flexible component is a corrugated pipe. Beneficial effects: In this solution, a corrugated pipe is used as the first flexible component. The flexibility of the corrugated pipe can reduce the transmission of vibration, and the corrugated structure of the pipe can also reduce noise.

[0017] Furthermore, an engine pull plate is installed inside the casing, and a protective cover is installed between the inverter and the engine pull plate. Beneficial effects: In this solution, the protective cover between the inverter and the engine pull plate isolates the inverter from the engine pull plate, thus preventing damage to the inverter wiring when the engine pull plate is pulled. It also prevents noise generated during engine operation from being transmitted, achieving a noise reduction effect.

[0018] Furthermore, a carbon monoxide detector is installed at the air inlet. Beneficial effect: In this solution, placing the carbon monoxide detector at the air inlet results in better detection performance. Attached Figure Description

[0026] The basic implementation examples are as follows: Figures 1-5 As shown: A generator set includes a housing and a working device located within the housing. The housing includes a mounting frame 1 and multiple panels. The mounting frame 1 is provided with multiple support beams 11, and the contact portions of adjacent panels abut against the support beams 11. Among the multiple panels, one panel is a main control panel 15, which is provided with multiple operating components for controlling the working device, including a power socket, a fuel switching switch 14, an engine pull handle 13, etc. A push handle 12 is provided on the side of the mounting frame 1 where the main control panel 15 is located.

[0027] Another panel has an air inlet, which includes an air filter inlet 32 ​​and an air guide hood inlet 31. On the opposite panel, there is an air outlet 33.

[0028] The outer casing includes an inner chamber formed by the internal flow channels of the working device and an outer chamber formed by the inner wall of the outer casing and the outer surface of the working device. Specifically, the working device includes an engine 2, an air filter 27, a resonant cavity 25, an oil-air mixing device 24, and a muffler 22. The air filter inlet 32, air filter 27, resonant cavity 25, oil-air mixing device 24, engine 2, and muffler 22 are connected sequentially. The muffler 22 is connected to the air outlet 33. The resonant cavity 25 and the air filter 27 are connected by a first flexible member 26. Air flows through the channels in the working device to form the inner chamber, and the part of the outer casing other than the working device is the outer chamber. In this embodiment, the first flexible member 26 is a bellows. In other embodiments, the first flexible member 26 can also be other elastic connecting members.

[0029] The inner chamber is connected to the outer chamber. Specifically, in this embodiment, the engine 2 is provided with a wind deflector 20, and the wind deflector 20 is provided with an inlet and an exhaust port 201, such as... Figure 2 As shown, the exhaust vent 201 is connected to the outer chamber. The engine 2 has a cooling channel inside, and the air guide shroud 20 has an air inlet. The inlet and the air inlet are sealed together by a flexible connector 21. The outlet of the cooling channel is connected to the air outlet 33. In this embodiment, the flexible connector 21 is a corrugated pipe. In other embodiments, the flexible connector 21 can also be other flexible connecting devices.

[0030] The housing also houses the engine 2 pull plate and the inverter 23. A protective cover is provided between the inverter 23 and the engine 2 pull plate. A mounting cavity is provided on the panel portion of the air inlet 31 facing inwards from the housing. The mounting cavity is located between the inlet and the air intake. The inverter 23 is located within the mounting cavity and directly opposite the air intake. A flexible connector 21 is provided between the mounting cavity and the air guide 20. In this embodiment, the flexible connector 21 is a bellows; in other embodiments, other elastic connectors may also be used. A carbon monoxide detector is also provided within the mounting cavity near the air intake.

[0031] The specific implementation process is as follows: During use, a portion of the external air enters the housing through the air inlet 31 of the air inlet shroud, then passes through the vents on the air inlet shroud 20 and enters the cooling channel inside the engine 2. The air in the cooling channel cools the interior of the engine 2 and then flows out of the housing through the air outlet 33, forming the first channel inside the engine 2. Figure 3 As shown; during this process, some of the air inside the engine 2 will enter the outer chamber through the exhaust port 201 on the air guide shroud 20, so that the outer chamber is kept under positive pressure, thereby achieving the dustproof and waterproof effect of the generator set.

[0032] A portion of the external air enters the air filter 27 through the air filter inlet 32. After being filtered by the air filter 27, it passes through the first flexible member 26 and enters the resonant cavity 25. After noise reduction within the resonant cavity 25, it enters the oil-air mixing device 24 and finally enters the engine 2, participating in combustion and becoming exhaust gas. It is then discharged from the exhaust port through the muffler 22, forming the second channel. Figure 4 As shown.
