[0027] The embodiments of the present application provide a high-efficiency collection multi-stage purification smokeless catering vehicle, as shown in Figure 1 and Figure 2 The high-efficiency collection multi-stage purification smokeless catering vehicle includes a rack 10, a crossbeam 12, a first stand 14, and an oil fume treatment device 18.

[0028] The top of the rack 10 is used to make food for customers, and oil fume will be generated during the making process.

[0029] The cross beam 12 located above the rack 10 defines a first horizontal flue, and is provided with a top smoke inlet opening downwardly and in communication with the first horizontal flue. The oil fume treatment device 18 generates negative pressure in the first horizontal flue inside the cross beam 12 when in operation, and the oil fume rising from the top of the rack 10 enters the first horizontal flue from the top smoke inlet opening.

[0030] The first column 14 is arranged on the rack 10 and connected with the cross beam 12, and defines a first vertical flue in communication with the first horizontal flue. The part of the first column 14 between the cross beam 12 and the rack 10 is provided with a lateral smoke inlet opening in communication with the first vertical flue.

[0031] The oil fume treatment device 18 generates negative pressure in the first vertical flue inside the first column 14 when in operation, and the floating oil fume and part of the rising oil fume enter the first vertical flue from the lateral smoke inlet opening, thereby avoiding the problem that the floating oil fume is dispersed into the air due to the long distance between the oil fume generation position and the top smoke inlet opening. Moreover, the oil fume in the first horizontal flue enters the oil fume treatment device 18 after passing through the first vertical flue.

[0032] The oil fume treatment device 18 is installed in the rack 10, and the inlet of the oil fume treatment device 18 is in communication with the first vertical flue. The oil fume treatment device 18 is configured to suck the oil fume from the top smoke inlet opening and the lateral smoke inlet opening and purify the oil fume entering therein.

[0033] The high-efficiency collection multi-stage purification smokeless catering vehicle provided by the embodiment of the present application can suck the rising oil fume from the top smoke inlet opening into the first horizontal flue, and suck the floating oil fume in the rising process from the lateral smoke inlet opening into the first vertical flue. The form of simultaneous top suction and lateral suction of oil fume improves the collection rate of oil fume, thereby avoiding the floating of oil fume and creating a good dining environment.

[0034] Further, as shown in Figure 1 the high-efficiency collection multi-stage purification smokeless catering vehicle further comprises a first filter plate 20 and a second filter plate 22. The first filter plate 20 is installed at the top smoke inlet opening, and the second filter plate 22 is installed at the lateral smoke inlet opening. The first filter plate 20 and the second filter plate 22 can filter out large particles of oil, thereby reducing the working load of the oil fume treatment device 18. Specifically, the first filter plate 20 is detachably connected to the top smoke inlet opening by screw connection or clamping connection. Similarly, the second filter plate 22 is detachably connected to the lateral smoke inlet opening by screw connection or clamping connection. When the high-efficiency collection multi-stage purification smokeless catering vehicle is used for a period of time, more oil will be attached to the first filter plate 20 and the second filter plate 22. Therefore, the first filter plate 20 and the second filter plate 22 can be detached for cleaning.

[0035] Continuing to refer to Figure 1The high-efficiency collection multi-stage purification smokeless food and beverage vehicle further comprises a second vertical column 16 arranged on the rack 10, the second vertical column 16 defines a second vertical flue, and a first air outlet is arranged in the second vertical column 16 and communicates with the second vertical flue. The outlet of the oil fume treatment device 18 communicates with the second vertical flue, and the oil fume treatment device 18 discharges clean air after treating the oil fume, and the clean air is discharged from the first air outlet through the second vertical flue in the second vertical column 16.

[0036] Specifically, the first air outlet is located at a portion of the second vertical column 16 above the cross beam 12, so that the first air outlet is located at a high position, preventing the discharged air from affecting the purchase experience of customers. Of course, in other embodiments of the present application, the first air outlet can also be arranged at other positions of the second vertical column 16.

[0037] As shown in Figure 1 and Figure 2 , the high-efficiency collection multi-stage purification smokeless food and beverage vehicle further comprises a top beam 24 arranged on the top of the cross beam 12, the top beam 24 defines a second horizontal flue, and a second air outlet is arranged in the top beam 24 and communicates with the second horizontal flue; wherein the second air outlet faces the food preparation side, and the second horizontal flue communicates with the first air outlet. In the embodiments of the present application, the food preparation side refers to the position of the sales personnel when preparing food.

[0038] When the oil fume treatment device 18 is working, the air in the second vertical flue is discharged from the first air outlet and enters the second horizontal flue in the top beam 24, and finally discharged into the air from the second air outlet. The second air outlet facing the food preparation side can prevent the discharged air from blowing to the customers, reducing the influence of the discharged air on the customers.

[0039] Referring to Figure 1 , further, the high-efficiency collection multi-stage purification smokeless food and beverage vehicle further comprises a third filter plate 26, the third filter plate 26 is installed on the second air outlet. The third filter plate 26 can further filter out a small amount of residual grease, and can block leaves, rainwater and the like from entering the high-efficiency collection multi-stage purification smokeless food and beverage vehicle. Specifically, the third filter plate 26 is connected to the second air outlet in a detachable manner by screw connection or clamping connection, etc.; when the high-efficiency collection multi-stage purification smokeless food and beverage vehicle is used for a period of time, grease and sundries will accumulate on the third filter plate 26, and the third filter plate 26 can be detached for cleaning.

[0040] As shown in Figure 1 , the high-efficiency collection multi-stage purification smokeless food and beverage vehicle provided by the embodiments of the present application further comprises a side beam 72 arranged on the top surface of the rack 10, the side beam 72 defines a third horizontal flue, and a bottom smoke inlet is arranged in the side beam 72 and communicates with the third horizontal flue and faces the food preparation side. One end of the side beam 72 is connected to the first vertical column 14, and the third horizontal flue communicates with the first vertical flue.

[0041] The oil fume treatment device 18 generates negative pressure in the third transverse flue inside the side beam 72 when in operation, and part of the oil fume generated on the top surface of the platform 10 is sucked into the third transverse flue through the bottom smoke inlet. The oil fume in the third transverse flue enters the oil fume treatment device 18 through the first vertical flue.

[0042] Further, with continuous reference to Figure 1 The high-efficiency collection multi-stage purification smokeless food and beverage vehicle further comprises a fourth filter plate 74 installed on the bottom smoke inlet, which can filter out large particles of oil in the oil fume and reduce the working load of the oil fume treatment device 18. Specifically, the fourth filter plate 74 is detachably connected to the bottom smoke inlet by screw connection or clamping connection, etc. When the high-efficiency collection multi-stage purification smokeless food and beverage vehicle is used for a period of time, more oil will be attached to the fourth filter plate 74, and the fourth filter plate 74 can be removed for cleaning.

[0043] As shown in Figure 2 The high-efficiency collection multi-stage purification smokeless food and beverage vehicle further comprises a first shielding plate 28 located on the food taking side and a second shielding plate 30 located on the food taking side; the first shielding plate 28 is connected to the first column 14 and the second column 16 and extends downward to the top of the platform 10; the second shielding plate 30 is connected to the first column 14 and the second column 16 and extends upward to the cross beam 12; and the second shielding plate 30 is located above the first shielding plate 28, forming a channel for transferring goods between the first shielding plate 28 and the second shielding plate 30.

[0044] The first shielding plate 28 and the second shielding plate 30 can block the oil fume from drifting towards the customers and separate the customers from the area where the food is prepared, preventing the droplets generated by the customers from entering the food during the communication process. The food and beverage seller can wear a mask to prevent his own droplets from entering the food. The channel between the first shielding plate 28 and the second shielding plate 30 can transfer food, tableware, etc.

[0045] Exemplarily, the first shielding plate 28 and the second shielding plate 30 can be transparent acrylic plates, which can facilitate communication between the customers and the food and beverage seller.

[0046] Specifically, as shown in Figure 1 The oil fume treatment device 18 comprises a mechanical filter unit 32, an oil fume treatment device 34, a flow equalization and pressure equalization variable diameter unit 36, and a fan 38 connected in sequence; wherein the inlet of the mechanical filter unit 32 is in communication with the first vertical flue.

[0047] The mechanical filtering unit 32 can filter out larger grease and dust in the oil fume and can arrange the airflow so that the airflow can enter the oil fume processor 34 uniformly. The fan 38 is used to generate the power of the gas flow, and the uniform flow and pressure variable diameter unit 36 can connect the fan 38 with the oil fume processor 34 and arrange the airflow.

[0048] Exemplarily, the oil fume processor 34 is an electrostatic oil fume processor 34, which ionizes the gas by using a stainless steel ionizer, and makes the particulate matter charged by a strong electric field to become charged particles. The charged particles are immediately adsorbed by the collecting electrode after hitting the second-stage dust collector, and more than 90% of the pollutants are filtered out, which can effectively collect particles greater than 0.1 microns, so as to achieve a gas meeting the environmental emission requirements.

[0049] The first filter plate 20, the second filter plate 22, the mechanical filtering unit 32, the electrostatic oil fume processor 34, and the third filter plate 26 form a multi-stage filtering processing mode, which greatly improves the efficiency of oil fume purification.

[0050] The fan 38 will vibrate during work. In order to reduce the influence of the vibration of the fan 38 on the food preparation on the table stand 10 and ensure the connection of the fan 38 with the uniform flow and pressure variable diameter unit 36, as shown in Figure 1 The oil fume treatment device 18 further includes a base 40, a plurality of damping units 42, and a connecting hose 44. The base 40 is located in the table stand 10 and is arranged at the bottom of the table stand 10. The fan 38 is connected to the base 40 through the plurality of damping units 42. The two ends of the connecting hose 44 are respectively connected to the uniform flow and pressure variable diameter unit 36 and the fan 38.

[0051] The vibration generated by the fan 38 is buffered by the plurality of damping units 42, and the vibration transmitted to the base 40 is smaller. Moreover, the fan 38 is connected to the uniform flow and pressure variable diameter unit 36 through the connecting hose 44, which realizes a soft connection. When vibrating, the hose is deformed, which can prevent the connection from being disconnected and ensure that the uniform flow and pressure variable diameter unit 36 and the fan 38 are always in communication.

[0052] Exemplarily, the damping unit 42 can be a spring damper.
