[0030] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0031] In the first embodiment, referring to Figures 1-3 as shown, a manual-automatic integrated rotary pizza oven includes a rotary disk assembly 1, a one-way rotation mechanism 2, an electric drive device 3, and a manual drive device 4 provided in a furnace body.

[0032] The rotary disk assembly 1 includes a rotating shaft 11, a tray 12, a fixed seat 10, and a first bearing 13. The first bearing 13 is provided in the fixed seat 10, the rotating shaft 11 is vertically rotatably provided in the first bearing 13, the top of the rotating shaft 11 is connected and fixed to the tray 12, that is, the rotating shaft 11 drives the tray 12 to rotate. A shaft sleeve 14 for fixing the rotating shaft 11 is provided in the fixed seat 10.

[0033] The bottom surface of the fixed seat 10 is connected to a first bracket 30 through a connecting rod 7. The electric drive device 3 is provided on the first bracket 30. The one-way rotation mechanism 2 is provided between the first bracket 30 and the fixed seat 10. The bottom surface of the fixed seat 10 is provided with a second bracket 40, and the manual drive device 4 is provided on the second bracket 40.

[0034] The electric drive device 3 is a motor. The one-way rotation mechanism 2 is a ratchet device 5. The ratchet device 5 includes a male ratchet 51, a female ratchet 52, and an elastic member. The output shaft of the motor is in transmission connection with the female ratchet 52. The male ratchet 51 is in transmission connection with the bottom of the rotating shaft 11 and the male ratchet 51 moves relative to the female ratchet 52 between moving away and abutting. The elastic member has a tendency to move the male ratchet 51 to abut against the female ratchet 52. The opposite surfaces of the male ratchet 51 and the female ratchet 52 are both provided with ratchet teeth, and the ratchet teeth enable the male ratchet 51 to rotate positively relative to the female ratchet 52.

[0035] The manual driving device 4 includes a driven gear 41, a second bearing 42, a manual rotating rod 44 and a driving gear 43. The driven gear 41 is sleeved on the rotating shaft 11. The second bearing 42 is installed on the second bracket 40. The manual rotating rod 44 is horizontally and rotatably connected to the second bearing 42. The inner end of the manual rotating rod 44 is in transmission connection with the driving gear 43. The driving gear 43 and the driven gear 41 are in meshing transmission. The outer end of the manual rotating rod 44 extends out of the furnace body. Preferably, the driven gear 41 is a driven bevel gear, the driving gear 43 is a driving bevel gear, and the manual rotating rod 44 is arranged perpendicular to the rotating shaft 11.

[0036] The elastic member is a first spring 53. The first spring 53 is sleeved on the rotating shaft 11. The top of the first spring 53 abuts against the driven gear 41, and the bottom of the first spring 53 abuts against the male ratchet 51.

[0037] In this embodiment, the pizza oven includes three working modes.

[0038] Working mode 1: Only the electric driving device 3 works. The output shaft of the electric driving device 3 drives the female ratchet 52 to rotate forward. The male ratchet 51 and the female ratchet 52 are meshed. The female ratchet 52 drives the male ratchet 51 to rotate forward. The forward rotation of the male ratchet 51 drives the rotating shaft 11 to rotate forward. Further, the rotating shaft 11 drives the tray 12 to rotate forward. At the same time, since the forward rotation of the rotating shaft 11 also drives the driven gear 41 to rotate forward, the manual rotating rod 44 and the driving gear 43 also rotate forward accordingly. In this mode, the electric driving device 3 provides the rotating power for the tray 12, and the electric driving device 3 controls the rotating speed of the tray 12.

[0039] Working mode 2: Only the manual driving device 4 works. The manual rotating rod 44 drives the driving gear 43 to rotate forward. The driving gear 43 drives the driven gear 41 to rotate forward. The forward rotation of the driven gear 41 drives the rotating shaft 11 to rotate forward. Further, the rotating shaft 11 drives the tray 12 to rotate forward. Since the electric driving device 3 stops working, that is, the female ratchet 52 stops rotating, the rotating shaft 11 drives the male ratchet 51 to rotate forward. The male ratchet 51 can rotate forward relative to the female ratchet 52 against the force of the first spring 53. In this mode, the manual driving device 4 provides the rotating power for the tray 12, and the manual driving device 4 controls the rotating speed of the tray 12.

[0040] Working mode 3: The electric driving device 3 and the manual driving device 4 work. The output shaft of the electric driving device 3 drives the female ratchet 52 to rotate forward. The male ratchet 51 and the female ratchet 52 are meshed. The female ratchet 52 drives the male ratchet 51 to rotate forward. The forward rotation of the male ratchet 51 drives the rotating shaft 11 to rotate forward. Further, the rotating shaft 11 drives the tray 12 to rotate forward. At the same time, since the forward rotation of the rotating shaft 11 also drives the driven gear 41 to rotate forward, the manual rotating rod 44 and the driving gear 43 also rotate forward accordingly.

[0041] When the forward rotation speed of the moving rotating rod driving the rotating shaft 11 is greater than the forward rotation speed of the female ratchet wheel 52 driving the male ratchet wheel 51, the male ratchet wheel 51 rotates forward relative to the female ratchet wheel 52, that is, the manual driving device 4 provides the rotation power for the tray 12, and the manual driving device 4 controls the rotation speed of the tray 12.

[0042] When the forward rotation speed of the manual rotating rod 44 driving the rotating shaft 11 is less than the forward rotation speed of the female ratchet wheel 52 driving the male ratchet wheel 51, the electric driving device 3 provides the rotation power for the tray 12, and the electric driving device 3 controls the rotation speed of the tray 12.

[0043] See Figures 4-6 As shown in the figure, in the second embodiment, the difference from the first embodiment is that the one-way rotation mechanism 2 is an overrunning clutch 6. The overrunning clutch 6 includes a lower seat 61, an upper seat 62, a second spring 63 and a limit block 64. The upper seat 62 rotates relative to the outer periphery of the lower seat 61. An installation position is provided on the outer periphery of the lower seat 61. The second spring 63 and the limit block 64 are placed in the installation position 65. One end of the second spring 63 abuts against the lower seat 61, and the other end of the second spring 63 abuts against the limit block 64. The second spring 63 makes both sides of the limit block 64 abut against the lower seat 61 and the upper seat 62 respectively. The electric driving device 3 is rotationally connected to the lower seat 61, and the rotating shaft 11 is rotationally connected to the upper seat 62.

[0044] When the electric driving device 3 drives the lower seat 61 to rotate forward, the lower seat 61 and the upper seat 62 cooperate with the second spring 63 to clamp the limit block 64, that is, the frictional force of the limit block 64 makes the lower seat 61 drive the upper seat 62 to rotate forward.

[0045] When the manual driving device 4 drives the rotating shaft 11 to drive the upper seat 62 to rotate forward, the upper seat 62 compresses the second spring 63 by the limit block 64, that is, the limit block 64 retracts into the installation position 65, and the upper seat 62 can rotate forward relative to the lower seat 61.

[0046] In the present utility model, the forward rotation refers to a fixed rotation direction. For example, in the first embodiment and the second embodiment, the forward rotation is the counterclockwise rotation direction.
