[0056] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0057] Example 1

[0058] This embodiment provides a method for controlling gas circulation in a disinfection cabinet, wherein a fan and a heating device are arranged in the disinfection cabinet. Specifically, the fan corresponding to the target preset position mentioned in this embodiment refers to the fan whose wind acts on the target preset position. Figure 1 As shown, the gas circulation control method comprises the following steps:

[0059] S11, sampling the temperatures of several preset positions in the disinfection cabinet to obtain the sampling temperatures of the preset positions.

[0060] S12: Determine the position of the tableware to be sterilized in the disinfection cabinet according to the sampling temperature.

[0062] S14. Determine a target preset position from the plurality of preset positions according to the air outlet direction.

[0063] Step S14 specifically includes the following steps:

[0064] S141. Determine the air path in the disinfection cabinet according to the air outlet direction.

[0065] S142: Determine a preset position between two adjacent fans through which the wind path passes as a target preset position.

[0066] S15, calculating the air volume at the target preset position according to the preset target temperature and the sampled temperature at the target preset position. Determining the air path in the disinfection cabinet according to the air outlet direction;

[0067] A preset position between two adjacent fans through which the wind path passes is determined as a target preset position.

[0068] Step S15 specifically includes the following steps:

[0069] The following formula is used to calculate each target preset position:

[0070] Where k is a positive integer;

[0071] Specifically, the above formula only involves numerical operations and does not involve units, where L k It represents the air volume at the target preset position when the kth temperature sampling is performed on the target preset position, in cubic meters per minute, E j It represents the difference between the preset target temperature of the preset target position and the sampling temperature obtained when the j-th temperature sampling is performed on the preset target position, in degrees Celsius, a is the proportional coefficient, b is the integral coefficient, and c is the differential coefficient.

[0072] S16. Calculate the rotation speed of the fan corresponding to the target preset position according to the wind volume at the target preset position.

[0073] Step S16 specifically includes the following steps:

[0074] S161. Determine a functional relationship between the air volume at the target preset position and the rotation speed of the fan that discharges air at the target preset position.

[0075] The functional relationship is:

[0076]

[0077] Specifically, the above formula only involves numerical operations and does not involve units, where L Tx Preset position T for the target x The air volume at the location is in cubic meters per minute, v i The i-th air outlet acts on the target preset position T x The fan speed, p i is the preset position T between the i-th and the target x The corresponding airflow out of the fan passes through the target preset position T x The attenuation coefficient when N is the wind acting on the target preset position T x The number of fans.

[0078] S162. Calculate the rotation speed of the fan at the target preset position according to the function expression and the wind volume at the target preset position.

[0079] S17, controlling the fan to operate according to the air outlet direction and the rotation speed.

[0080] The following are three specific cases of applying the embodiment of the method. It should be noted that the determination of the wind direction of the fan and the selection of the target preset position in the following three cases are only used to conveniently and clearly assist in explaining the purpose of the embodiment of the present invention. In fact, the general placement of tableware in the box is different, and the determination of the wind direction of the fan and the selection of the target preset position will also be different, which should not be a limitation of the embodiment of the present invention.

[0081] Case 1:

[0082] Ti represents the sampled temperature obtained by sampling the temperature at the preset position Ti, and L represents the sampled temperature. Ti Indicates the air volume at the preset position Ti, in cubic meters per minute, expressed as v a Indicates the speed of fan A, with v b Indicates the speed of fan B, with v cDenote the rotational speed of the fan C. During the initial stage of heating, temperature sampling is performed at preset positions. When the sampling results are T1 < T2 < T3 and T4 < T5 < T6, it is determined that the positions of the tableware in the box are mainly concentrated on the left side. To obtain the best drying effect, the hot air near the heating device at the lower part of the box should be conveyed to the left side along the shortest path to heat the tableware on the left side, that is, determine the air outlet directions of the three fans as Figure 2 shown by the arrow directions in. Determine the target preset positions as T1, T3, and T5 from the several preset positions according to the air outlet directions, and calculate L according to T1, T3, and T5 T1 , L T3 , L T5 . Since the air outlet of fan B acts on the target preset position T1, the air outlet of fan A acts on the target preset position T3, and the air outlet of fan C acts on the target preset position T5, thus obtaining L T1 , L T3 , L T5 and the functional relationship between the rotational speeds of fans A, B, and C is:

[0083]

[0084]

[0085]

[0086] Calculate L T1 , L T3 , L T5 according to the temperature closed-loop control, and substitute them into the above formula to solve, obtaining:

[0087]

[0088]

[0089]

[0090] And remove the solutions that do not meet the conditions to obtain the rotational speeds of different fans.

[0091] Case 2:

[0092] Use Ti to represent the sampling temperature obtained by temperature sampling at the preset position Ti, use L Ti to represent the air volume at the preset position Ti, with the unit of cubic meters per minute, use v a to represent the rotational speed of fan A, use v b to represent the rotational speed of fan B, use v cIndicates the speed of fan C. At the beginning of heating, the temperature of the preset position is sampled. When the sampling results are T1>T2>T3, T4>T5>T6, it is determined that the tableware in the box is mainly concentrated on the right side. In order to obtain the best drying effect, the hot air near the heating device at the bottom of the box should be transported to the right side via the shortest path to heat the tableware on the right side, that is, the air outlet directions of the three fans are determined as follows: Figure 3 According to the wind direction, the target preset positions are determined as T1, T3, and T5 from the preset positions, and L is calculated according to T1, T3, and T5. T1 , L T3 , L T5 Because the air from fan B acts on the target preset position T5, the air from fan A acts on the target preset position T1, and the air from fan C acts on the target preset position T3, we get L T1 , L T3 , L T5 The functional relationship between the speed of fans A, B, and C is:

[0093]

[0094]

[0095]

[0096] According to the temperature closed-loop control calculation, L T1 , L T3 , L T5 , respectively into the above formula to solve, we get:

[0097]

[0098]

[0099]

[0100] By removing the solutions that do not meet the conditions, the speeds of different fans can be obtained.

[0101] Case 3:

[0102] Ti represents the sampled temperature obtained by sampling the temperature at the preset position Ti, and L represents the sampled temperature. Ti Indicates the air volume at the preset position Ti, in cubic meters per minute, expressed as v a Indicates the speed of fan A, with v b Indicates the speed of fan B, with v cRepresents the rotational speed of fan C. Temperature sampling is performed at preset positions in the initial stage of heating. When the sampling results are T1>T2<T3 and T4>T5<T6, it is determined that the positions of the tableware in the cabinet are mainly concentrated in the middle. To obtain the best drying effect, the hot air near the heating device at the lower part of the cabinet should be conveyed to the middle along the shortest path to heat the tableware in the middle. That is, the air outlet directions of the three fans are determined as Figure 4 shown by the arrow directions in T2 . According to the air outlet direction, the target preset position is determined as T2 from the several preset positions, and L is calculated based on T2 T2 . Since the rotational directions of fans B and C are opposite, the airflows converge and rise in the middle to heat the middle side. Therefore, the air outlets of fans B and C act on the target preset position T2, and thus L

[0103] and the functional relationship between the rotational speed of fans B and C is: c and v b ;

[0104] L is calculated according to the temperature closed-loop control. T2 Substitute them into the above formula respectively to solve, and we get:

[0105]

[0106] And remove the solutions that do not meet the conditions, then the rotational speeds of different fans can be obtained.

[0107] The gas circulation control method of the disinfection cabinet in this embodiment obtains the sampling temperature by performing temperature sampling at several preset positions in the disinfection cabinet. The position of the tableware to be disinfected in the disinfection cabinet is determined according to the sampling temperature, and the air outlet direction of the fan is determined according to the position of the tableware to be disinfected in the disinfection cabinet. Then, the target preset position is determined from the several preset positions according to the air outlet direction, and the air volume at the target preset position is calculated according to the sampling temperature at the target preset position. Then, the rotational speed of the fan corresponding to the target preset position is calculated according to the air volume at the target preset position. Finally, the fan is controlled to operate according to the air outlet direction and the rotational speed to ensure that the tableware in the disinfection cabinet can be evenly heated, solving the problems of uneven heating of the disinfection cabinet body and too long drying time.
