[0008] In one optional embodiment, the engineering machinery equipment further includes: an interior trim piece disposed on the side of the front bulkhead facing the cab body and obscuring the air conditioner, the interior trim piece having at least two air vents, each of the air vents being connected to at least one other air vent.

[0009] Beneficial effects: Interior trim can cover the air conditioner and front panel, improving the cleanliness of the driver's cabin, reducing the probability of dust and liquid entering the air conditioner and front panel, and will not affect the air conditioner's airflow into the driver's cabin.

[0010] In one alternative embodiment, the housing has a clearance groove on the side facing the interior space of the driver's cab, and the interior space of the driver's cab has an operating table that extends into the clearance groove.

[0011] Beneficial effects: It can avoid interference between the air conditioner and the control panel without changing the original cab layout, and ensure that the air conditioner can be installed in the front bulkhead.

[0012] In one alternative embodiment, the two air vents are located on the side of the housing facing the interior trim and on opposite sides of the clearance groove.

[0013] Beneficial effects: It can make full use of the surface of the shell, and the distance between the air outlet and the air outlet inside the cabin is relatively close, which helps to shorten the air outlet distance and improve the air outlet efficiency.

[0014] In one optional embodiment, the interior trim piece has two recessed portions on the side facing the air conditioner, and the groove wall of the recessed portion is provided with the cabin air outlet, with each air outlet area inserted into the recessed portion.

[0015] Beneficial effects: Interior trim is more compatible with the air conditioner, avoiding interference between the two and ensuring the air conditioner's working efficiency.

[0016] In one alternative embodiment, the cab further includes a cover plate detachably connected to the front bulkhead on the side facing away from the cab body, the cover plate shielding the air conditioner.

[0017] Beneficial effects: The cover can be removed to inspect or replace the air conditioner, making air conditioner maintenance more convenient and maximizing the use of the interior space of the driver's cab.

[0018] In one alternative embodiment, the external circulation port is located on the cover plate.

[0019] Beneficial effects: The closer distance between the external circulation port and the air inlet of the air conditioner can improve airflow efficiency and reduce energy consumption.

[0020] In one optional embodiment, the heat exchanger includes a heating core and a cooling core, which are arranged in a vertical direction.

[0021] Beneficial effects: The air conditioner can heat up and cool down the cab, which helps to improve the applicable scenarios of construction machinery and equipment, and makes it more comfortable.

[0037] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0038] According to an embodiment of the present invention, an engineering machinery equipment 1 is provided, which includes a cab 100 and an air conditioner 200.

[0039] The cab 100 is equipped with an external air circulation port. The air conditioner 200 is installed in the cab 100 and includes a housing 210, a heat exchanger 220, a filter 230, and two fans 240. The housing 210 has an air inlet 211 and two air outlets 212 in its circumferential direction. The air inlet 211 is connected to the internal space of the cab 100 and the external air circulation port, and the air outlets 212 are connected to the internal space of the cab 100. The filter 230 is connected to the housing 210 and is located at the air inlet 211. The heat exchanger 220 and the two fans 240 are located inside the housing 210. The two fans 240 are located on opposite sides of the length of the heat exchanger 220 and correspond one-to-one with the two air outlets 212. Specifically, on a plane perpendicular to the axis of the air inlet 211, the projection of the heat exchanger 220 and the projection of the air inlet 211 at least partially coincide; on a plane perpendicular to the axis of the air outlet 212, the projection of the air outlet 212 and the corresponding projection of the fan 240 at least partially coincide.

[0040] For example, the construction machinery equipment 1 can be an excavator, crane, bulldozer, loader, road roller, paver, grader, forklift, piling machinery, stacker, tractor, shuttle bus, etc. The filter element 230 can be a filter screen, filter paper, electrostatic precipitator filter element, or other filter devices with dust filtration functions. The fan 240 can be a centrifugal fan 240.

[0041] Furthermore, the air outside the cab 100 can flow through the external circulation port to the air inlet 211 of the air conditioner 200, then through the filter 230 and heat exchanger 220, and finally through the air outlet 212 into the interior space of the cab 100, which is external circulation; the air inside the cab 100 can flow through the air inlet 211 of the air conditioner 200, then through the filter 230 and heat exchanger 220, and finally through the air outlet 212 back into the interior space of the cab 100, which is internal circulation.

[0042] In some embodiments, the cab 100 may be equipped with a switch structure for opening and closing the external air circulation port. In this case, the external air circulation mode can be selectively opened or closed to prevent external air from continuously entering the interior space of the cab 100, allowing the temperature inside the cab 100 to be adjusted to the driver's set temperature more quickly. In other embodiments, the cab 100 may not have a switch structure for opening and closing the external air circulation port, meaning the external air circulation mode can be in a normally open state, reducing the number of parts. The switch structure can be optionally installed on the engineering machinery equipment 1 of this utility model to make the engineering machinery equipment 1 suitable for different working scenarios.

[0043] In this utility model of engineering machinery equipment 1, the gas inside the cab 100 and the gas outside the cab 100 are guided by two fans 240, and then converge in front of the air inlet 211 before flowing to the heat exchanger 220. The gas exchanges heat with the heat exchanger 220. Under the guidance of the two fans 240, the heat-exchanged gas is divided into two airflows, which turn and flow into the cab 100 from the two air outlets 212.

[0044] Furthermore, the filter element 230 is installed at the air inlet 211, which can filter the gas flowing to the heat exchanger 220, remove dust and other impurities from the gas, and ensure the cleanliness of the gas flowing into the air conditioner 200 and the cab 100.

[0045] In other words, the air conditioner 200, through a single air inlet 211, enables both internal and external air circulation in the vehicle, and the filter 230 simultaneously filters both the internal and external airflow. Compared to existing air conditioners that simultaneously have internal and external air inlets, the air conditioner 200 of the engineering machinery equipment 1 of this invention has a simpler structure and can reduce the number of filter elements 230.

[0046] In addition, the air conditioner 200 of this utility model can change the gas flow direction by means of the fan 240. In a limited space, two fans 240 are arranged on both sides of the heat exchanger 220 along its length, which shortens the distance between the air conditioner 200 and the air outlet 132 in the cabin. While ensuring effective regulation of the gas in the cab 100, the volume of the air conditioner 200 can be reduced, thereby improving the space utilization of the engineering machinery equipment 1.

[0047] like Figure 2 As shown, in some embodiments, the cab 100 includes a front bulkhead 120 and a cab body 110. The front bulkhead 120 is located in front of the cab body 110, and an air conditioner 200 is installed on the front bulkhead 120. Two air outlets 212 are spaced apart in the left-right direction.

[0048] Due to the limited size of the cab 100 of the construction machinery equipment 1, especially the cab 100 of some small and micro construction machinery equipment 1, the air conditioner in the related technology is arranged outside the cab. For example, the air conditioner is generally arranged at the rear or top of the cab. Therefore, an additional housing device is required to arrange the air conditioner 200, resulting in the inefficient use of the interior space of the cab. The wiring and piping design of the air conditioner are complicated, and since the working conditions of the construction machinery equipment 1 are often harsh, the air conditioner is also prone to damage.

[0049] This utility model, by installing the air conditioner 200 on the front bulkhead 120, is equivalent to placing at least a part of the air conditioner 200 inside the cab 100, making reasonable use of the interior space of the cab 100. Furthermore, the air conditioner 200 is closer to the air outlet 132 in the cabin, effectively reducing the complexity of the wiring and piping of the air conditioner 200, reducing air loss, and even if the engineering machinery equipment 1 is used in harsh working conditions, the air conditioner 200 is not easily damaged.

[0050] like Figure 1 and 2 As shown, in some embodiments, the engineering machinery equipment 1 also includes an interior trim 130, which is located on the side of the front bulkhead 120 facing the interior space of the cab 100. The interior trim 130 covers the air conditioner 200 and has at least two cabin air vents 132, each air vent 212 being connected to at least one cabin air vent 132.

[0051] In this way, the interior trim 130 can cover the air conditioner 200 and the front panel 120, improve the cleanliness of the cab 100, reduce the probability of dust and liquid entering the air conditioner 200 and the front panel 120, and will not affect the air conditioner 200's airflow into the cab 100.

[0052] For example, the interior trim 130 may also have more cabin air vents 132. For instance, the interior trim 130 may have two first cabin air vents 1321 and two second cabin air vents 1322. The two first cabin air vents 1321 are located on the upper surface of the interior trim 130, and the two second cabin air vents 132 are located on the rear surface of the interior trim 130. The first cabin air vents 1321 can blow air towards the glass of the cab 100 or the driver's face, and the second cabin air vents 1322 can blow air towards the driver's feet or the driver's body.

[0053] like Figure 3 and Figure 4 As shown, in some embodiments, the housing 210 has a clearance groove 213 on the side facing the cab, and the cab body 110 has an operating table 150 that extends into the clearance groove 213. By setting the clearance groove 213, the air conditioner 200 can be prevented from interfering with the operating table 150 without changing the original layout of the cab 100, ensuring that the air conditioner 200 can be arranged on the front bulkhead 120.

[0054] Furthermore, two air vents 212 are located on the side of the housing 210 facing the interior trim 130, and the two air vents 212 are located on opposite sides of the clearance groove 213. In this way, the surface of the housing 210 can be fully utilized, and the distance between the air vents 212 and the cabin air vent 132 is relatively close, which helps to shorten the air outlet distance, improve air outlet efficiency, and prevent the air from the air vents 212 from blowing directly onto the driver's face through the first cabin air vent 1321, thereby improving comfort.

[0055] The air inlet 211 is located on the side of the housing 210 facing away from the cockpit, or the air inlet 211 is located on the upper side of the housing 210.

[0056] like Figure 1 and Figure 2 As shown, the interior trim 130 has two recessed portions 131 on the side facing the air conditioner 200. The walls of the recessed portions 131 are provided with cabin air vents 132, and each air vent 212 is inserted into the recessed portion 131. For example, the bottom wall of the recessed portion 131 can be provided with a second cabin air vent 1322, and the top wall of the recessed portion 131 can be provided with a first cabin air vent 1321. This makes the interior trim 130 more compatible with the air conditioner 200, avoiding interference between them and ensuring the operating efficiency of the air conditioner 200.

[0057] like Figure 2 As shown, in some embodiments, the construction machinery equipment 1 further includes a cover plate 140, which is detachably connected to the side of the front bulkhead 120 facing away from the cab body 110. The cover plate 140 covers the air conditioner 200. The cover plate 140 is connected to the front bulkhead 120 by bolts. When the cover plate 140 is removed, the air conditioner 200 can be inspected or the filter 230 replaced, making maintenance of the air conditioner 200 more convenient and maximizing the use of the interior space of the cab 100.

[0058] Furthermore, the external circulation port is located on the cover plate 140. In this way, the external circulation port is closer to the air inlet 211 of the air conditioner 200, which can improve airflow efficiency and reduce energy consumption.

[0059] As shown in the figure, in some embodiments, the heat exchanger 220 includes a heating core and a cooling core, which are arranged vertically. In this way, the air conditioner 200 can heat and cool the interior of the cab 110, which is beneficial for improving the applicability of the construction machinery equipment 1 and providing greater comfort.

[0060] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the appended claims.
