Description

Technical Field

[0001] This utility model relates to a closed generator. Background Technology

[0002] A closed-type generator is a generator set that houses the generator unit, engine unit, and components such as the air filter connected to the engine unit in a relatively enclosed box-like shell.

[0003] Chinese patent document CN213870070U discloses a generator set, including a cabinet, an engine, a generator, a muffler, and an air filter. The cabinet has a partition that divides its interior into a first cavity and a second cavity. The engine, generator, and muffler are all located in the first cavity, and the air filter is located in the second cavity. The air filter is connected to the engine's intake pipe via a connecting pipe. The cabinet has an air inlet for supplying outside air into the second cavity. One end of the second cavity has an opening with a mounting plate inside. The air filter includes an air filter housing and a filter element located within the housing. The filter element is detachably connected to the connecting pipe. The air filter housing is fixed to the mounting plate. The air filter housing has an inspection port with a first cover plate detachably connected to it.

[0004] The beneficial effects of the above-mentioned prior art solution are as follows: During operation, cold air from the outside enters the second accommodating cavity through the air inlet, and then the air in the second accommodating cavity enters the engine through the air filter and connecting pipe in sequence, providing oxygen for the combustion of fuel in the engine; under the separation effect of the baffle, the hot air in the first accommodating cavity will not enter the second accommodating cavity, so that the air temperature in the second accommodating cavity is lower, and the air with a higher temperature in the first accommodating cavity is less likely to heat the air filter, thereby making the temperature of the air entering the engine through the air filter lower, which can reduce the engine temperature and improve the engine working efficiency.

[0005] In practical use, the aforementioned existing technical solution involves fresh air supplying the engine entering the air filter housing through the intake port at the bottom. After being filtered by the filter element, the air collects in the middle of the filter element. Then, the air moves downwards along the axial direction of the filter element and enters the connecting pipe. Finally, the air flows laterally under the influence of the connecting pipe and enters the engine. With the increasing number of electrical devices, higher demands are being placed on the output power of the hermetic generator. This increase in the output power of the hermetic generator also means that the engine power needs to be increased, which in turn means that the amount of fresh air required by the engine also needs to be increased.

[0006] However, using the existing technology described above requires increasing the size of the air filter element to meet the filtration requirements of more fresh air. As a result, the overall size of the air filter increases accordingly, necessitating a larger space for the generator set to install it. This leads to a significant increase in the overall size of the generator set, potentially making the original space insufficient for installation and causing inconvenience to users.

[0007] Therefore, how to increase the output power of a closed-loop generator without significantly increasing its size has become an urgent technical problem to be solved. Utility Model Content

[0008] The purpose of this invention is to provide a closed-loop generator to solve the problem that increasing the output power of a closed-loop generator in the prior art can easily lead to a significant increase in size.

[0009] To achieve the above objectives, the basic solution of this utility model provides a closed generator, including a housing, an engine and an air filter are arranged inside the housing, and an air intake pipe is connected between the air filter and the engine; the air filter includes a housing and a cylindrical filter element, the housing is provided with an air inlet and an air outlet, the air outlet is connected to the air intake pipe, the filter element is arranged horizontally, and the air outlet is coaxially arranged with the filter element.

[0010] The beneficial effects of this basic solution are as follows: By arranging the filter element laterally and coaxially with the air outlet, the filtered air moves directly axially to the air outlet and enters the intake pipe. This reduces large-angle turns of the air during flow, making the airflow in the intake pipe smoother and thus meeting the intake requirements of the engine after power increases. Compared with existing technologies, this solution eliminates the need to increase the volume of the air filter to meet the engine's intake requirements after power increases, thus avoiding a significant increase in the overall size of the enclosed generator due to the increased size of the air filter. This achieves the effect of increasing the output power of the enclosed generator without causing a significant increase in size, facilitating the installation and setup of the enclosed generator.

[0011] Preferably, the air outlet is located on the side of the housing facing the engine. This arrangement reduces the formation of large-angle bends in the intake pipe when connecting the air filter and the engine, thereby allowing for smoother airflow within the intake pipe, reducing air pressure loss, and further ensuring the engine's air intake requirements.

[0012] Preferably, the air inlet is located at the bottom of the housing and is in the form of a porous tube. This arrangement helps reduce intake noise and also reduces the diffusion of noise from inside the air filter outward through the air inlet, thus improving the quietness of the enclosed generator.

[0013] Preferably, the air inlets are located on both sides of the bottom of the housing. This arrangement helps the air filter to disperse the incoming air, avoiding excessive concentration of air and resulting in air pressure loss, which further helps to ensure the improved output power of the enclosed generator.

[0014] This utility model has the following beneficial effects: Compared with existing technologies, this solution eliminates the need to increase the volume of the air filter to meet the engine's intake requirements after increasing the engine's power. This avoids the situation where the volume of the entire enclosed generator increases significantly due to the increase in the volume of the air filter, thus achieving the effect of increasing the output power of the enclosed generator without causing a significant increase in volume, which facilitates the installation and setup of the enclosed generator.

Detailed Implementation

[0016] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: outer casing 1, air intake pipe 2, filter element 3, engine 4, housing 5, air outlet 6, and air inlet 7.

[0017] The basic implementation examples are as follows: Figures 1 to 4 As shown: A closed generator includes a housing 1. In this embodiment, the housing 1 is rectangular. An engine 4 and an air filter are disposed inside the housing 1. An intake pipe 2 connects the air filter and the engine 4. Fresh air is filtered by the air filter and then enters the engine 4 through the intake pipe 2 for combustion.

[0018] The air filter includes a housing 5 and a cylindrical filter element 3. The housing 5 has an air inlet 7 and an air outlet 6. The filter element 3 is disposed inside the housing 5, separating the air inlet 7 from the air outlet 6. This allows fresh air to enter the housing 5 through the air inlet 7, pass through the filter element 3, and then exit the housing 5 through the air outlet 6, thus achieving the air filtration function of the filter element 3. The filter element 3 is arranged laterally, and the air outlet 6 is coaxially arranged with the filter element 3, allowing the air filtered by the filter element 3 to move directly along the axial direction of the filter element 3 to the air outlet 6.

[0019] The air outlet 6 is connected to the air intake pipe 2. The air outlet 6 is located on the side of the housing 5 facing the engine 4, so that the air intake pipe 2 can reduce the formation of a large-angle turning area when connecting the air filter and the engine 4, thereby making the air flow in the air intake pipe 2 smoother and reducing the loss of air pressure.

[0020] The air inlet 7 is located at the bottom of the housing 5 and is in the form of a porous tube, which helps to reduce intake noise and also helps to reduce the diffusion of noise from inside the air filter outward through the air inlet 7. More preferably, the air inlets 7 are distributed on both sides of the bottom of the housing 5.

[0021] After increasing the power of engine 4, this solution eliminates the need to increase the volume of the air filter to meet the intake requirements of engine 4. This avoids the situation where the volume of the entire enclosed generator increases significantly due to the increase in the volume of the air filter. Thus, it achieves the effect of increasing the output power of the enclosed generator without causing a significant increase in volume, which facilitates the installation and setup of the enclosed generator.

[0022] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics of the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or the practicality of the patent.
