[0002] The main function of a catering fume treatment station is to collect and purify the fumes generated during the catering process, prevent them from polluting the normal living environment of nearby residents, and ensure that the fume emissions meet environmental protection standards.

[0003] However, after a long period of operation, the internal temperature of a catering fume treatment station is high. The accumulated grease inside may spontaneously combust at high temperatures, especially when grease blocks the channels and causes the fumes to be discharged in a timely manner. The excessively high temperature of the chimney and fume duct makes it more likely to cause a fire. Summary of the Invention

[0006] In one possible implementation, the fan is positioned at the top of the catering fume treatment station, and the inlet of the heat dissipation duct is located near the top of the catering fume treatment station.

[0007] In one possible implementation, the inlet of the heat dissipation duct is located on the side above the direction of oil fume flow of the centrifugal fan of the catering fume treatment station.

[0011] The technical solutions provided in this application embodiment have at least the following technical effects:

[0012] The cooling device for a catering fume treatment station provided in this embodiment includes an electrical control box, a temperature sensor, heat dissipation ducts, and a fan.

[0020] Figure 1 and Figure 2The diagram shows the specific structure of the catering fume treatment station 10. The catering fume treatment station 10 includes a housing 11, a rectifier duct 12, a mechanical filter 13, an electrostatic fume purifier 14, a reducing unit 15, a flexible connecting pipe 16, a centrifugal fan 17, an exhaust duct section 18, and a rain cap 19. The rectifier duct 12, mechanical filter 13, electrostatic fume purifier 14, reducing unit 15, flexible connecting pipe 16, centrifugal fan 17, and outlet duct section 18 are connected in sequence, and a rain cap 19 is installed at the outlet of the outlet duct section 18; the mechanical filter 13, electrostatic fume purifier 14, reducing unit 15, flexible connecting pipe 16, and centrifugal fan 17 are located inside the housing 11; part of the rectifier duct 12 is located inside the housing 11, and the inlet of the rectifier duct 12 is located outside the housing 11; part of the outlet duct section 18 is located inside the housing 11, and the inlet of the outlet duct section 18 is located inside the housing 11, and the outside of the outlet duct section 18 is wrapped with a sound-absorbing layer 181.

[0021] This application provides a cooling device for a catering fume treatment center, such as... Figure 1 and Figure 2 As shown, the cooling device of the catering fume treatment station includes an electrical control box 20, a temperature sensor 30, a heat dissipation duct 40, and a fan 50. The temperature sensor 30 is located inside the catering fume treatment station 10 and is electrically connected to the electrical control box 20. It is used to monitor the temperature inside the catering fume treatment station 10 in real time and transmit the monitored temperature data to the electrical control box 20. The heat dissipation duct 40 is at least partially located inside the catering fume treatment station 10, and one end of the heat dissipation duct 40 is connected to the outside of the catering fume treatment station 10. The fan 50 is installed on the heat dissipation duct 40 and is electrically connected to the electrical control box 20. The electrical control box 20 can control the start and stop of the fan 50. When the fan 50 is started, it exhausts the hot air inside the catering fume treatment station 10 through the heat dissipation duct 40, allowing cold air from the outside to enter the catering fume treatment station 10, thus lowering the temperature inside the catering fume treatment station 10.

[0022] The electrical control box 20 is configured to control the start and stop of the fan 50 based on the temperature detected by the temperature sensor 30. When the internal temperature of the catering fume treatment station 10 exceeds a preset temperature threshold, the electrical control box 20 controls the fan 50 to start, and the fan 50 discharges the warmer air inside the catering fume treatment station 10 through the heat dissipation duct 40. When the internal temperature of the catering fume treatment station 10 is lower than the preset temperature threshold, the electrical control box 20 controls the fan 50 to stop working. This cooling device of the catering fume treatment station can cool down the catering fume treatment station 10, preventing the internal temperature from becoming too high, thereby avoiding the spontaneous combustion of accumulated oil.

[0023] like Figure 1 As shown, the fan 50 is installed on the top of the catering fume treatment station 10, and the inlet of the heat dissipation pipe 40 is close to the top of the catering fume treatment station 10.

[0024] Because hot air has a lower density, the hot air inside the catering fume treatment station 10 will rise to near the top of the catering fume treatment station 10, so that the inlet of the heat dissipation duct 40 is close to the top of the catering fume treatment station 10, making it easier for the fan 50 to quickly exhaust the hot air.

[0025] like Figure 1 and Figure 2 As shown, the inlet of the heat dissipation duct 40 is located above the direction of oil fume flow of the centrifugal fan 17. Specifically, in Figure 1 and Figure 2 In this configuration, the oil fume flows from left to right, and the heat dissipation duct 40 is located to the left of the centrifugal fan 17. When the electrical control box 20 starts the motor, the hot air in the catering oil fume treatment station 10 flows from the right side of the centrifugal fan 17 to the left and enters the heat dissipation duct 40. This allows the hot air to carry away some of the heat from the centrifugal fan 17 and the exhaust duct section 18 while flowing, thus achieving a better cooling effect.

[0026] Reference Figure 2 As shown, the heat dissipation pipe 40 in this embodiment includes a first branch pipe 41, a second branch pipe 42, and a main heat dissipation pipe 43. The first end 43a of the main heat dissipation pipe 43 is connected to the outside of the catering fume treatment station 10, and a fan 50 is installed on the main heat dissipation pipe 43. The first branch pipe 41 and the second branch pipe 42 are located inside the catering fume treatment station 10. One end of the first branch pipe 41 and one end of the second branch pipe 42 are both connected to the second end 43b of the main heat dissipation pipe 43, opposite to the first end 43a. The other ends of the first branch pipe 41 and the second branch pipe 42 extend in a direction perpendicular to the direction of fume flow.

[0027] When the electrical control box 20 starts the fan 50, the hot air in the catering fume treatment station 10 enters the heat dissipation main duct 43 from the first branch pipe 41 and the second branch pipe 42, and is discharged from the heat dissipation main duct 43. The arrangement of the first branch pipe 41 and the second branch pipe 42 allows the hot air to circulate around the electrostatic fume purifier 14, the centrifugal fan 17 and the air outlet duct section 18 before entering the first branch pipe 41 and the second branch pipe 42. This allows the hot air to carry away the heat from the surfaces of the electrostatic fume purifier 14, the centrifugal fan 17 and the air outlet duct section 18 while being discharged from the catering fume treatment station 10, achieving a better cooling effect.

[0028] Furthermore, the free ends of the first branch pipe 41 and the second branch pipe 42 both extend beyond the centrifugal fan 17 of the catering fume treatment station 10 in a direction perpendicular to the flow of oil fumes. The free ends of the first branch pipe 41 and the second branch pipe 42 refer to the ends of the first branch pipe 41 and the second branch pipe 42 that are far from the main heat dissipation pipe 43, respectively.

[0029] like Figure 1 and Figure 2 As shown in the embodiment of this application, the cooling device for the catering fume treatment station also includes a temperature sensing bracket 60; the temperature sensing bracket 60 is disposed on the top of the catering fume treatment station 10; wherein, the temperature sensing probe 30 is installed on the temperature sensing bracket 60. The temperature sensing bracket 60 provides a mounting base for the temperature sensing probe 30, and since hot air rises to monitor the top of the catering fume treatment station 10, the temperature sensing bracket 60 places the temperature sensing probe 30 on the top of the catering fume treatment station 10, enabling the temperature sensing probe 30 to monitor the temperature at the top of the catering fume treatment station 10.
