The tray pushing device 300 is installed inside the cabinet 100 and is used to push the trays 600 inside the cabinet 100. The escapement device 400 is installed inside the cabinet 100 and is used to stop and release the trays 600 inside the cabinet 100, so as to realize the tray dispenser dispensing the trays 600 one by one. The heating module 500 is installed inside the cabinet 100 and is used to heat the trays 600 by heating the air inside the tray dispenser.

[0057] The "one at a time" can be one at a time, or it can be any number of two, three, etc.

[0058] The following text will provide a detailed explanation of the above-mentioned components and their interrelationships with reference to the accompanying drawings.

[0059] like Figures 1 to 5 As shown, in some embodiments of the present invention, the cabinet 100 has opposing first sidewalls 110 and second sidewalls 120. A dishing opening 111 is provided at the bottom of the first sidewall 110 so that plates 600 inside the cabinet 100 can be dispensed through the dishing opening 111. At least one partition 130 for placing plates 600 is provided inside the cabinet 100, spaced vertically at intervals. The partition 130 divides the internal space of the cabinet 100 into at least one receiving space 101 for placing plates 600 and a heating space 102 located below the receiving space 101. The heating space 102 is used to house a heating module 500.

[0060] from Figures 1 to 4 As can be seen, in some embodiments of the present invention, the first side wall 110 is the left side wall of the cabinet 100, and the second side wall 120 is the right side wall of the cabinet 100. Furthermore, those skilled in the art can, as needed, set the first side wall 110 as the right side wall of the cabinet 100 and the second side wall 120 as the left side wall of the cabinet 100.

[0061] from Figures 1 to 4 It can also be seen that in some embodiments of the present invention, the number of partitions 130 is specifically three, which defines three accommodating spaces 101 and one heating space 102 in the cabinet 100. In addition, those skilled in the art can also set the number of partitions 130 to any other feasible number as needed, such as one, two, four, five, etc.

[0062] from Figures 1 to 4It can also be seen that, in some embodiments of the present application, gaps (not labeled in the figure) are provided between the partitions 130 and the first side wall 110, so that each tray 600 above each partition 130 can fall through its corresponding gap to the tray outlet 111.

[0063] As shown in Figures 1 to 4 some embodiments of the present application, an arc-shaped plate (not labeled in the figure) is further provided between the lowermost partition 130 and the first side wall 110, one end of the arc-shaped plate is connected to the end of the lowermost partition 130 close to the first side wall 110, and the other end of the arc-shaped plate is connected to the bottom end of the tray outlet 111 on the first side wall 110. Those skilled in the art can understand that the arc-shaped plate can receive the trays 600 falling from the partitions 130 and make the trays 600 smoothly slide to the tray outlet 111.

[0064] Further, in order to prevent or reduce the noise caused by the trays 600 hitting the arc-shaped plate, a shock-absorbing pad (such as a sponge pad, a silica gel pad, etc.) can be attached to the upper surface of the arc-shaped plate, and a smooth plastic film can be attached to the shock-absorbing pad to ensure that the trays 600 smoothly slide to the tray outlet 111.

[0065] As shown in Figure 3 , Figure 4 and Figure 6 , the cabinet door 210 is pivotally connected to the cabinet body 100 and is used to open and cover the cabinet body 100. The cabinet door 210 and the cabinet body 100 can be pivotally connected by a hinge or a hinge.

[0066] As shown in Figure 3 , Figure 6 and Figure 7 , the side door 220 is rotatably connected to the two vertical side walls of the tray outlet 111 through its bottom end. Specifically, the bottom end of the side door 220 is provided with a rotating shaft (not labeled in the figure), and the two vertical side walls of the tray outlet 111 are respectively provided with rotating shaft holes, and the rotating shaft is embedded in the rotating shaft holes, so as to realize the pivotal connection between the side door 220 and the cabinet body 100. Alternatively, those skilled in the art can also install the side door 220 on the cabinet body 100 in a rotatable manner by means of a pin shaft, a screw or a bolt according to the needs. For example, the rotating shaft on the side door 220 is replaced by a hole structure, and the corresponding rotating shaft hole on the cabinet body 100 is provided as a threaded hole, and the bolt is screwed together after penetrating the hole structure and the threaded hole.

[0067] As shown in Figure 3 and Figure 4 , the trays 600 sliding out of the tray outlet 111 will slide onto the opened side door 220 and be carried by the side door 220.

[0068] As shown in Figure 7As shown, the side door 220 is further provided with a baffle 221 at the end away from the rotation shaft and the other two sides, which is used to stop the tray 600 on it from sliding to the ground. Wherein, the baffle 221 on each side is further provided with a connecting hole 2211.

[0069] From Figures 1 to 3 it can be seen that the first side wall 110 of the cabinet 100 is further provided with a sink (not labeled in the figure) above the tray opening 111, the bottom end of the sink is connected with the tray opening 111, and the depth of the sink is greater than or equal to the thickness of the side door 220 (including the baffle 221), so as to accommodate the side door 220, so that the side door 220 will not protrude from the first side wall 110 when shielding the tray opening 111 (as shown in Figure 6 Further, the side door 220 can also abut against the bottom wall of the sink through the baffle 221.

[0070] As shown in Figure 1 and Figure 3 , the two vertical side walls of the tray opening 111 are further provided with a sliding groove 112 respectively, and the tray machine further comprises one or two connecting rods 230. The two ends of the connecting rod 230 are respectively provided with connecting shafts (not labeled in the figure), one of the two connecting shafts is inserted into the connecting hole 2211 on the side door 220, so as to realize the pivotal connection between the connecting rod 230 and the side door 220; one of the two connecting shafts is inserted into the sliding groove 112 on the first side wall 110, so as to realize the sliding connection between the connecting rod 230 and the first side wall 110.

[0071] Those skilled in the art can understand that when the side door 220 is opened to the use position as shown in Figure 3 and Figure 4 , the side door 220 will force the connecting rod 230 to slide downward away from one end of the connecting rod 230 to the bottom end of the sliding groove 112, and thus give the side door 220 a pulling force in the vertical direction, so that the side door 220 is kept in the position as shown in Figure 3 and Figure 4 When the side door 220 is rotated to the closed position as shown in Figure 6 , the side door 220 will force the connecting rod 230 to slide upward away from one end of the connecting rod 230 to the top end or top of the sliding groove 112, so as to ensure that the side door 220 can shield the tray opening 111.

[0072] Further, although not shown in the figure, in some embodiments of the present application, the tray machine further comprises a locking device for locking the side door 220 to the shielding position as shown in Figure 6 The locking device can be any feasible device. For example, the locking device comprises an iron block fixedly connected with or integrally formed with the side door 220 and a magnet fixed to the first side wall 110, when the side door 220 is rotated to the shielding position as shown in Figure 6The locking device is shown in the figure. The magnet and the iron block are attracted together, thereby fixing the side door 220 to the current position.

[0073] Further, although not shown in the figure, in some embodiments of the present application, the outer side of the side door 220 can also be provided with a handle to facilitate the user to open the side door 220.

[0074] As Figures 1 to 4 shown, in some embodiments of the present application, the push plate device 300 is fixedly connected with the cabinet 100, and the push plate device 300 is configured to push the dinner plate 600 on the partition plate 130 in the direction of the first side wall 110 along the second side wall 120 opposite to the first side wall 110, and each push plate device 300 corresponds to one partition plate 130.

[0075] Specifically, as Figure 8 shown, the push plate device 300 includes a first motor 310 fixedly connected with the cabinet 100, a lead screw 320 drivingly connected with the first motor 310, and a push plate assembly 330 engaged with the lead screw 320, the axial direction of the lead screw 320 is parallel to the left-right direction of the dinner plate machine, so that the push plate assembly 330 pushes the dinner plate 600 to move towards the first side wall 110 under the action of the first motor 310.

[0076] Among them, the first motor 310 can be fixedly connected with the second side wall 120 through its shell 531. For example, the first motor 310 and the second side wall 120 are screwed together through screws or bolts.

[0077] Further, the push plate device 300 further includes at least one guide rod 340 fixedly connected with the cabinet 100, the guide rod 340 is parallel to the lead screw 320 and is slidingly connected with the push plate assembly 330.

[0078] Specifically, as Figure 8 shown, the push plate assembly 330 is arranged in a rectangular shape, and the push plate device 300 includes three guide rods 340. One corner of the push plate assembly 330 above is provided with a threaded hole 3301 matched with the lead screw 320, and the other three corners of the push plate assembly 330 are respectively provided with open holes 3302, so that the push plate assembly 330 is engaged with the lead screw 320 through the threaded hole 3301, and is slidingly connected with the guide rod 340 through the open hole 3302.

[0079] As Figures 1 to 5 shown, the top wall and the bottom wall of the accommodating space 101 are respectively provided with two fixed rails 140 with U-shaped grooves, so that the lead screw 320 and the guide rod 340 are respectively embedded in the corresponding U-shaped grooves, thereby fixing the lead screw 320 and the guide rod 340 in the radial direction through the fixed rail 140.

[0080] Optionally, the guide rod 340 is also fixedly connected with the second side wall 120 in the axial direction, and the fixed connection can be welding, bolt connection, etc. For example, the guide rod 340 is provided with a threaded hole at one end close to the second side wall 120, the second side wall 120 is provided with a through hole corresponding to the threaded hole, and a bolt is screwed together through the through hole and the threaded hole.

[0081] Further, as can be seen from Figure 3 and Figure 4 , the tray 600 is placed on the two guide rods 340 below to reduce the resistance when the tray 600 slides. Preferably, the surface of the guide rod 340 is a smooth surface. Further, the tray 600 abuts the guide rod 340 through its arc-shaped transition corner, so that a small part of the tray 600 is located below the top end of the guide rod 340, thereby fixing the tray 600 in the front and rear direction of the tray machine.

[0082] As can be seen from Figures 1 to 5 , the cabinet 100 is divided into at least one containing space 101 for placing the tray 600 by the partition 130, and at least one of the top wall and the bottom wall of the containing space 101 is the partition 130. Specifically, the top wall of the uppermost containing space 101 is the top wall of the cabinet 100, and the bottom wall is the partition 130; the top wall of the lowermost containing space 101 is the partition 130, and the bottom wall is the bottom wall of the cabinet 100.

[0083] Continuing to refer to Figure 8 , the push plate assembly 330 includes a driving plate 331, a spring 332 and an abutting plate 333 fixedly connected in sequence. One corner above the driving plate 331 is provided with a threaded hole 3301, and the other three corners of the driving plate 331 and the four corners of the abutting plate 333 are all provided with open holes 3302, so that the driving plate 331 is engaged with the lead screw 320 through the threaded hole 3301 and is slidingly connected with the guide rod 340 through the open hole 3302; and the abutting plate 333 is slidingly connected with the guide rod 340 through the open hole 3302.

[0084] Among them, the driving plate 331 and the abutting plate 333 can be respectively welded, clamped or bolted together with one end of the spring 332, etc.

[0085] Those skilled in the art can understand that, in some embodiments of the present application, by arranging the spring 332 between the driving plate 331 and the abutting plate 333, the push plate device 300 can press the tray 600 through the spring 332. If there is no spring 332, only the first motor 310 drives the lead screw 320 to press the tray 600, which may not be able to press the tray 600 tightly, or the pressure may be too large to damage the tray 600.

[0086] It should be noted that, under the premise of realizing the above functions, the number of springs 332 is not limited toFigure 8 The four shown can also be any other feasible number, such as one, two, three, five, etc.

[0087] Furthermore, the cross-sections of the threaded hole 3301 and the open hole 3302 are both any value between 1 / 3 and 1 / 2 of a circle, and the cross-sections of the U-shaped groove of the fixed rail 140 are both any value between 1 / 3 and 1 / 2 of a circle. For example, the cross-sections of the threaded hole 3301 and the open hole 3302 are both 1 / 2 of a circle, and the cross-sections of the U-shaped groove of the fixed rail 140 are both 1 / 4 of a circle.

[0088] Those skilled in the art will understand that the aforementioned dimensions of the threaded hole 3301, the open hole 3302, and the U-shaped groove are used to fix the lead screw 320 and the guide rod 340 radially with the threaded hole 3301 and the open hole 3302 respectively and the opposite U-shaped groove, and the drive plate 331 and the abutment plate 333 will not interfere with the fixed rail 140.

[0089] Furthermore, the pusher assembly 330 may also include a proximity switch (not shown) disposed between the drive plate 331 and the abutment plate 333, and the pusher device 300 is configured to control the first motor 310 to stop rotating when the proximity switch is triggered.

[0090] The proximity switch can be any feasible device, such as a reed switch, Hall sensor, photoelectric sensor, etc.

[0091] For example, a reed switch is provided on the side of the drive plate 331 facing the abutment plate 333, and a magnet is provided on the abutment plate 333. When the spring 332 is compressed to the point that the reed switch is triggered by the magnet, the first motor 310 is controlled to stop rotating. The wire connected to the reed switch is arranged on the upper side of the drive plate 331.

[0092] Those skilled in the art will understand that by setting a proximity switch, the maximum elastic force of the spring 332 can be limited to prevent damage to the plate 600, while the spring 332 can continue to provide pressure to the remaining plates 600 after one plate 600 is released.

[0093] like Figures 1 to 5 As shown, in some embodiments of the present invention, the escapement 400 is fixedly connected to the cabinet 100. The escapement 400 is configured to stop the plates 600 on the partition 130 and is capable of releasing the plates 600 on the partition 130 so that the plates 600 on the partition 130 fall one by one toward the dish opening 111 through the gap. In the present invention, each partition 130 corresponds to at least one escapement 400.

[0094] like Figure 4As shown, in some embodiments of the present invention, the top of each plate 600 in each receiving space 101 has a certain space for arranging the escapement device 400.

[0095] like Figure 5 As shown, in some embodiments of the present invention, an escapement device 400 may be provided on the upper and lower sides of each receiving space 101.

[0096] Furthermore, the upper and lower sidewalls of each receiving space 101 respectively have fixing structures for fixing the escapement device 400 (such as... Figure 5 (The unmarked structure shown) is used to securely mount the escapement 400 to the cabinet 100 via this fixing structure.

[0097] The escapement device 400 on the lower side of the receiving space 101 is located below the lower side wall of the receiving space 101 to prevent unnecessary interference between the lower escapement device 400 and the plate 600 inside the receiving space 101.

[0098] Furthermore, a clearance hole 132 is provided on the lower side wall of the receiving space 101 at the position corresponding to the escapement device 400, so as to ensure that the escapement device 400 (specifically the escape lever 420) on the lower side of the receiving space 101 can stop and release the plate 600.

[0099] like Figures 9 to 11 As shown, in some embodiments of the present invention, the escapement device 400 includes a housing 410 fixedly connected to the cabinet 100. The housing 410 can be connected or welded to the fixing structures on the upper and lower sides of the aforementioned receiving space 101 using screws / bolts. When using screws / bolts, an outwardly extending fixing seat can be provided on the housing 410, and a hole structure allowing bolts and screws to pass through can be provided on the fixing seat.

[0100] Continue reading Figure 9 and Figure 11 In some embodiments of the present invention, the escapement device 400 further includes a second motor 430 disposed outside the housing 410. The second motor 430 can be fixedly connected to the housing 410 by bolts or screws. For this purpose, the housing 410 has corresponding screw holes on its side wall for fixing the second motor 430.

[0101] Continue reading Figure 9 and Figure 11In some embodiments of the present application, the escapement device 400 further comprises two escapement levers 420 arranged in the housing 410 and each in sliding connection with the housing 410. Specifically, the housing 410 is provided with two sliding holes (not labeled in the figure) on the opposite side walls, and each of the two escapement levers 420 is in sliding connection with the two sliding holes respectively. Further, each of the two escapement levers 420 is further provided with a rack.

[0102] As shown in Figure 11 In some embodiments of the present application, the escapement device 400 further comprises a gear set 401 arranged in the housing 410, and each gear in the gear set 401 is in rotational connection with the housing 410. The gear set 401 is used to transmit the power of the second motor 430 to the two escapement levers 420, so that one of the two escapement levers 420 extends while the other retracts.

[0103] As shown in Figure 11 In some embodiments of the present application, the housing 410 comprises a first side shell 411 and a second side shell 412 fixedly connected. Those skilled in the art can understand that by arranging the housing 410 in the form of the first side shell 411 and the second side shell 412, it is convenient to install the gear set 401 and the two escapement levers 420 on the housing 410.

[0104] Wherein, the first side shell 411 and the second side shell 412 can be fixedly connected by any feasible means such as welding, bolt connection, etc.

[0105] As shown in Figure 12 and Figure 13 In some embodiments of the present application, the gear set 401 comprises a driving gear 440, a driven gear 450, a first transmission gear 461, a second transmission gear 462 and a third transmission gear 463.

[0106] As shown in Figures 11 to 13 The driving gear 440 comprises a forward driving half-tooth structure 441 and a reverse driving half-tooth structure 442 distributed along its axial direction. Wherein, the forward driving half-tooth structure 441 and the reverse driving half-tooth structure 442 can be understood as half of the gear, simply referred to as half gear. In other words, the driving gear 440 comprises two half gears fixed coaxially, and the two half gears are the same, but the area where the teeth of each half gear are located has an included angle. That is, one of the two half gears is rotated by an angle relative to the other, so that the two half gears are staggered in the circumferential direction.

[0107] As shown in Figure 12 and Figure 13As shown, the driven gear 450 includes coaxially fixed input gear 451 and output gear 452 engaged with two pallets 420, wherein the input gear 451 can be engaged with the first driving gear 461 and the third driving gear 463 respectively. For this purpose, the axial dimension of the input gear 451 can be greater than or equal to the sum of the axial dimensions of the first driving gear 461 and the third driving gear 463.

[0108] As shown in Figure 12 , Figure 14 and Figure 15 , the first driving gear 461, the input gear 451, the second driving gear 462 and the third driving gear 463 are engaged in turn. And the driving gear 440 can be rotated to a position where the forward driving half-tooth structure 441 is engaged with the first driving gear 461, and thus the second motor 430 drives each gear in the gear set 401 to rotate in the direction shown by the dashed arrow in Figure 14 , and the power is transmitted in turn in the direction shown by the single solid arrow in Figure 14 . The driving gear 440 can also be rotated to a position where the reverse driving half-tooth structure 442 is engaged with the second driving gear 462, and thus the second motor 430 drives each gear in the gear set 401 to rotate in the direction shown by the dashed arrow in Figure 15 , and the power is transmitted in turn in the direction shown by the single solid arrow in Figure 15 .

[0109] Wherein, Figure 14 and Figure 15 , the double solid arrow indicates the direction of movement of the left edge of the output gear 452. Based on this, those skilled in the art can understand that when the second motor 430 drives the gear set 401 to rotate in the working state shown in Figure 14 , Figure 16 the right pallet 420 in Figure 16 moves downward (extends), Figure 15 the left pallet 420 in Figure 16 moves upward (retracts), Figure 16 the left pallet 420 in moves downward (extends).

[0110] Further, the first driving gear 461, the second driving gear 462 and the third driving gear 463 are identical, so that the lifting speed of the two pallets 420 is the same

[0111] In addition, in other embodiments of the present application, the skilled in the art can also omit the setting of the second transmission gear 462 and the third transmission gear 463 as needed, and make the reverse drive half-tooth structure 442 directly mesh with the input gear 451.

[0112] As shown in Figures 9 to 11 , the two escapement rods 420 each extend out of one end of the housing 410 and are provided with a wedge structure 421, so that the escapement rod 420 stops and releases the tray 600 through the wedge structure 421. Further, the two wedge structures 421 are opposite to each other, and the projection parts on the plane perpendicular to the front-to-back direction of the tray machine overlap (as shown in Figure 10 ).

[0113] The working principle of the escapement device 400 stopping and releasing the tray 600 will be briefly described below with reference to Figures 17 to 19 .

[0114] As shown in Figure 17 , one of the two escapement rods 420 with the wedge structure 421 facing the tray 600 locks the tray 600.

[0115] As shown in Figure 18 , when the second motor 430 drives the gear set 401 to rotate to the position where the wedge structure 421 of the other escapement rod 420 is just embedded between the two trays 600, the locking of the rear tray 600 is started, and the front tray 600 is squeezed through the wedge structure 421 of the rear tray 600.

[0116] As shown in Figure 19 , when the second motor 430 drives the gear set 401 to rotate to Figure 17 , the escapement rod 420 stopping the tray 600 is raised to be separated from the tray 600, and the other escapement rod 420 gradually squeezes the front tray 600, and thus releases the front tray 600.

[0117] Further, in the process of debugging the tray machine of the present application, the height of each escapement device 400 in the vertical direction can be adjusted to ensure that the escapement device 400 can realize the above-mentioned function, i.e. the one-by-one release of the tray 600 by the escapement device 400. Alternatively, the skilled in the art can also make the escapement device 400 release multiple (for example, two, three, four, etc.) trays 600 at the same time through this way as needed.

[0118] In order to realize the height adjustment of the escapement 400 in the vertical direction, a long slot extending in the vertical direction can be arranged on the fixing structure on the cabinet 100, a screw hole corresponding to the long slot can be arranged on the shell 410 of the escapement 400, and a screw is screwed to the screw hole after passing through the long slot. When the height of the escapement 400 needs to be adjusted, the screw is only needed to be loosened. After the height adjustment is completed, the screw is tightened again.

[0119] Further, in order to ensure that the dinner plates 600 can fall smoothly from the partition plate 130, the position of the escapement 400 can be arranged such that Figure 17 the left dinner plate 600 is located inside the end of the partition plate 130 close to the first side wall 110, so that Figure 19 the left dinner plate 600 is located outside the end of the partition plate 130 close to the first side wall 110. Alternatively, a protrusion can also be arranged on the bottom of the side of the abutting plate 333 away from the driving plate 331, so that the escapement 400 below the accommodation space 101 is located in front of the escapement 400 above the accommodation space 101, so as to make the dinner plates 600 on the partition plate 130 tilt, and then make the released dinner plates 600 slide under the action of their own gravity.

[0120] Further, the skilled person in the art can also set the inclination angle of the inclined surface of the wedge-shaped structure 421 to be large enough according to the need, so as to further ensure that the dinner plates 600 can fall smoothly from the partition plate 130.

[0121] As shown in Figure 20 and Figure 21 in some embodiments of the present application, the heating module 500 includes a sleeve 510, a heating device 520 and a fan 530. The sleeve 510 abuts the peripheral wall of the heating space 102 through its peripheral surface, the heating device 520 is installed on the sleeve 510, and the fan 530 is arranged in the sleeve 510 to drive the air heated by the heating device 520 to circulate between the accommodation space 101 and the heating space 102, so as to heat the dinner plates 600 in the accommodation space 101.

[0122] The heating device 520 can be an electric heating wire or a heating sheet with a plurality of air permeable holes.

[0123] In addition, the skilled person in the art can also arrange the heating device 520 and the fan 530 directly into the cabinet 100 according to the need, and the arrangement of the sleeve 510 can be omitted.

[0124] From Figure 20 and Figure 21It can be seen that the sleeve 510 has a rectangular cross section, and the fan 530 is an axial fan 530. The fan 530 is fixedly connected with the sleeve 510 through its casing 531, and the fixed connection can be a screw connection, a clamping connection, etc.

[0125] Further, the fan 530 is located at the rear side of the heating device 520, and the fan 530 is configured to drive the air in the sleeve 510 to flow from the fan 530 to the heating device 520. Alternatively, those skilled in the art can interchange the positions of the heating device 520 and the fan 530 according to needs.

[0126] Further, although not shown in the drawings, in some embodiments of the present application, the cabinet 100 can also be filled with thermal insulation materials inside at least one of the side walls thereof; and / or, a thermal insulation layer can be fixed to the inner or outer surface of at least one of the side walls of the cabinet 100 to prevent heat loss in the dish machine.

[0127] Referring back to Figure 5 A front gap (not labeled in the drawings) is formed between the front end of each partition plate 130 and the closed cabinet door 210, and a plurality of through holes 131 are arranged at the rear portion of each partition plate 130 to ensure that the air driven by the fan 530 can circulate between the accommodation space 101 and the heating space 102.

[0128] Alternatively, those skilled in the art can omit the through holes 131 arranged at the rear portion of the partition plate 130, and form a rear gap between the rear end of each partition plate 130 and the rear inner wall surface of the cabinet 100.

[0129] Further, the partition plate 130 is inclined downward from front to rear, so that the water flowing down from the dish 600 on the partition plate 130 flows to the rear gap or the through hole 131, and then flows downward into the heating space 102.

[0130] Those skilled in the art can understand that by inclining the partition plate 130 downward from front to rear, the water flowing down from the dish 600 is prevented from flowing toward the cabinet door 210, which affects the user's experience, and bacteria are prevented from accumulating on the partition plate 130.

[0131] Further, although not shown in the drawings, in some embodiments of the present application, the dish machine can also include an alcohol jug, an electric alcohol pump and a nozzle arranged in the heating space 102 and sequentially fluidly connected, the alcohol jug is used to contain medical disinfectant alcohol, the electric alcohol pump is used to deliver the alcohol in the alcohol jug to the nozzle to form alcohol spray, and then the alcohol spray flows to the accommodation space 101 under the action of the fan 530 to disinfect the dish 600. Since the technology for realizing this spraying function is prior art, and is a conventional technical means or common knowledge in the art, it will not be described here.

[0132] The use method and working principle of the tray machine will be described in detail below.

[0133] Firstly, the first motor 310 of the pushing disc device 300 is controlled to move the pushing plate assembly 330 to a position close to the second side wall 120.

[0134] For this purpose, the tray machine of the present application is further provided with a reset button, a reset sensor and a controller, the reset sensor being used to detect whether the first motor 310 of the pushing disc device 300 moves the pushing plate assembly 330 to a position close to the second side wall 120. The reset button, the reset sensor, the proximity switch and the first motor 310 are electrically connected to the controller respectively. When the user presses the reset button, the controller controls the first motor 310 to reverse, until the reset sensor is triggered by the pushing plate assembly 330. The reset sensor can be the same as the proximity switch described above.

[0135] Then, the user respectively places a plurality of trays 600 into each accommodation space 101.

[0136] Further, the tray machine of the present application is further provided with a start button electrically connected to the controller. When the start button is pressed, the controller controls the first motor 310 to rotate forward, until the proximity switch is triggered.

[0137] Then, the controller controls the electric alcohol pump and the fan 530 to work for a period of time (for example, 1 min, 3 min, 5 min, etc.), so that the electric alcohol pump delivers alcohol in the alcohol flask to the nozzle to form alcohol spray, and then the alcohol spray flows to the accommodation space 101 under the action of the fan 530, so as to disinfect the trays 600.

[0138] Then, the controller controls the heating device 520 and the fan 530 to work for a period of time (for example, 10 min, 30 min, 45 min, etc.), so as to heat the trays 600 in the tray machine.

[0139] Further, the tray machine of the present application is further provided with a tray delivery button electrically connected to the controller. When the user opens the side door 220 and presses the tray delivery button, the controller first controls the uppermost first motor 310 to rotate forward (stops rotating when the proximity switch is triggered), and controls all the second motors 430 corresponding to the uppermost accommodation space 101 to rotate at the same time, so that the trays 600 in the uppermost accommodation space 101 fall one by one and slide onto the side door 220 through the tray delivery opening 111. Then, the user can take out the trays 600 from the side door 220.

[0140] It should be noted that the above-mentioned discarding action can be continuous or discontinuous. When it is continuous, the discarding button is pressed and the above-mentioned action is continuously performed. When it is discontinuous, the discarding button is pressed once and the second motor 430 is controlled to rotate one circle.

[0141] Further, when the uppermost disc 600 is sent out, the pusher device 300 is controlled to reset the pusher assembly 330, and then the pusher device 300 and the escapement device 400 in the lower space are operated.

[0142] For this purpose, each space 101 is also provided with a detection switch electrically connected to the controller. When the disc 600 is sent out, the pusher assembly 330 can move to the position of triggering the detection switch with the continuous rotation of the first motor 310, so that the air control pusher device 300 is reset. The detection switch is arranged on the cabinet 100 and can be the same as the proximity switch described above.

[0143] Based on the above description, those skilled in the art can understand that the disc machine of the present application not only can realize the automatic dispensing of the disc 600, but also can heat the disc 600 to prevent the cold disc 600 from affecting the taste of the food.

[0144] In addition, in other embodiments of the present application, those skilled in the art can also omit the heating module 500 according to the needs.
