The assembly state of the mode movement mechanism is shown in fig. 8, and the specific working principle and process are as follows:
the mode track disk 3 rotates coaxially about a mode mounting post on the housing 11 (housing 11 is stationary). The dough blowing pull rod 4 is fixedly assembled with the dough blowing air door 5, and the dough blowing track column 43 of the dough blowing pull rod 4 is inserted into the dough blowing track groove 32 on the mode track disc 3. When the mode track disc 3 rotates, the face blowing track groove 32 drives the face blowing pull rod 4 to rotate around the face blowing air door shaft, so that the face blowing air door 5 is opened and closed.
The defroster damper 1 moves similarly to the blow face damper 5. The defrost track post of defrost lever 2 is inserted into defrost track slot 33 on modular track pad 3. When the mode track disc 3 rotates, the defrosting track groove 33 drives the defrosting pull rod to rotate around the defrosting air door shaft, so that the defrosting air door 1 is closed and opened.

the mode dial 3 is rotated to 75 ° to reach blow foot mode: after the face blowing air doors 5 are linked, the air doors 8 are all closed, the foot blowing air doors 9 are completely opened, and the defrosting mode is closed, as shown in fig. 11;
the mode dial 3 is rotated to 176 ° to reach the foot-blow defrost mode: after the face blowing air door 5 is linked, the air door 8 is still in a closed state, and the foot blowing air door 9 and the defrosting air door 1 are not completely opened, as shown in fig. 12;
the mode dial 3 is rotated to 220 ° to reach defrost mode: after the face blowing air door 5 is linked, the air door 8 is in a closed state and does not act, the foot blowing air door 9 is closed, and the defrosting air door 1 is completely opened, as shown in fig. 13;
as shown in fig. 14, 15, and 16, inflection points a1 to a5 in the blowing surface trajectory groove, inflection points B1 to B5 in the defrosting trajectory groove, and inflection points C1 to C7 in the blowing foot trajectory groove correspond to positions of the corresponding trajectory posts in the course of the damper from fully opened to closed. For the blowing surface track groove, A1 is the starting point, and the blowing surface air door is fully opened at the moment; at A2, the face blowing door begins to close; when A3, the face blowing air door is closed by half; at A4, the face blowing damper is completely closed; a5 is the end point, at which the blow side damper is closed. For the defrosting track groove, B1 is the starting point, and the defrosting air door is closed at the moment; b2, the defrosting air door is opened; b3, opening the defrosting air door by half; b4, the defrosting air door is completely opened; b5, the defrost damper is fully open. For the foot blowing track groove, C1 is the starting point, and the foot blowing air door is fully closed at the moment; c2, opening the foot blowing air door; c3, opening the air door by half; c4, fully opening the foot blowing air door; c5, closing the air door to the full; c6, fully closing the foot blowing air door; c7 is the end point, when the blow-down door is fully closed.
When the face blowing control device works, when the face blowing track column of the face blowing pull rod passes through the staggered position of the face blowing track groove and the defrosting track groove, the guide column is inserted into the face blowing track auxiliary groove of the face blowing pull rod, and at the moment, double-track control is performed, so that the smooth transition staggered position of the face blowing track column of the face blowing pull rod is ensured, and the fact that the face blowing track groove and the defrosting track groove are staggered without influencing normal rotation of an air door is realized. In addition, the face blowing track groove and the defrosting track groove are combined to have an overlapped common design, so that the overall compactness of the face blowing track groove and the defrosting track groove is improved, the design space is saved, and the overall occupied space of the mode motion mechanism can be effectively improved. The linkage of the face blowing air door and the rear air door is realized by the rear air door connecting rod, and the change of the proportion of the rear face blowing air quantity and the rear blowing air quantity is realized.
