Description

Technical Field

[0001] The invention relates to an intelligent cooking machine, and in particular to a seasoning injection component used for a frying pan of the intelligent cooking machine. Background Art

[0002] In the process of cooking dishes in the existing cooking machine, seasonings need to be added to season the dishes.

[0003] The applicant previously submitted a utility model patent application to the State Intellectual Property Office (application date: 2018.12.27, application number: 201822241430.9, title: "Pot cover assembly and pot cover device", authorization announcement date: 2020.01.17, announcement number: CN209951076U), which discloses an auxiliary material transfer tube used in a cooking machine, wherein the auxiliary material transfer tube is arranged on the pot cover, and the seasoning is injected into the pot through the auxiliary material transfer tube to season and color the dishes, effectively improving the taste and color of the dishes. However, the above structure has the following deficiencies:

[0004] Due to the space limitation of the wok station rotation, the auxiliary material transfer pipe fixed on the pot cover is short when the wok lid is closed, resulting in the seasoning falling directly on the inner wall of the upper part of the wok due to insufficient injection stroke, and then flowing down along the inner wall into the dish being cooked. In the case of high temperature, the seasoning evaporates before flowing into the dish and sticks to the inner wall of the wok. The residual seasoning in the high temperature environment easily causes the anti-stick coating of the wok to be corroded, which not only wastes the seasoning, but also makes it difficult to clean the pot wall.

[0030] The specific implementation of the present invention is further described in detail below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0031] Combination Figures 1 to 10 As shown, the seasoning injection assembly for the frying pan of the intelligent cooking machine of the present invention can accurately inject seasoning into the food and effectively reduce seasoning consumption, thereby improving the quality of dishes cooked by the cooking machine and effectively preventing the seasoning from sticking to the inner wall of the upper half of the frying pan.

[0032] The seasoning injection assembly 100 is mainly composed of a seasoning delivery pipe 1, a seasoning relay plate 2, a transmission mechanism for driving the seasoning relay plate 2 to move linearly, a limit switch 5 for limiting the moving stroke of the seasoning relay plate 2, and a driving motor 4 for providing power to the transmission mechanism.

[0033] 1. Seasoning delivery pipe

[0034] Combination Figure 1 and Figure 2 As shown, the seasoning delivery pipe 1 includes a main pipe 11 and a plurality of branch pipes 12. The main pipe 11 is cylindrical and has a main flow channel along the central axis. The branch pipes 12 are arranged obliquely on both sides of the main pipe 11 from front to back (the direction pointing to the wok 300 is the front, and the direction pointing to the opposite is the back, the same below). The seasoning outlet is arranged at the front end of the main pipe 11, and the branch pipes 12 are connected to the main flow channel of the main pipe 11. The number of branch pipes 12 can be set according to the number of seasonings, and each branch pipe 12 is corresponding to the delivery of one seasoning, so as to prevent the flavors of the seasonings from affecting each other, causing flavor cross-talk, and reducing the freshness and taste of the dishes.

[0035] The lower surface of the main pipe 11 is provided with a receiving track 13 for installing the seasoning relay plate 2, a pressure wheel installation position 14, and a mounting fixing position 16 for the frame plate assembly. The receiving track 13 is a long strip groove, so that the seasoning relay plate 2 can move smoothly in the receiving track 13.

[0036] like Figure 1 As shown, the seasoning delivery pipe 1 is fixedly installed on the rear surface of the pot cover 200. When the pot cover 200 is covered with the wok 300, the outlet of the main pipe 11 points into the pot.

[0037] 2. Seasoning relay board

[0038] Combination Figure 1 and Figure 2As shown, the seasoning relay plate 2 is in the shape of a long strip, and its upper surface (i.e., the side opposite to the main pipe 11) is a concave surface. After the seasoning relay plate 2 moves to the set position, the main pipe 11 of the seasoning delivery pipe 1 injects the seasoning into the concave surface of the seasoning relay plate 2, and enters the food in the wok 300 along the concave surface, effectively improving the utilization rate of the injected seasoning and improving the quality of the dishes cooked by the cooking machine. Preferably, in the embodiment of the present invention, in order to make the seasoning relay plate 2 move more smoothly and receive the seasoning, the concave surface is adapted to the lower surface of the main pipe 11.

[0039] 3. Transmission mechanism

[0040] The preferred transmission mechanisms of the present invention include the following two types:

[0041] (1) Rack and pinion transmission structure

[0042] like Figure 2 As shown, a rack 21 is provided at the rear of the lower surface of the seasoning relay plate 2 corresponding to the transmission structure, and the length of the rack 21 determines the maximum movable stroke of the seasoning relay plate 2.

[0043] Combination Figure 2 and Figure 3 As shown, a frame plate assembly is provided below the seasoning relay plate 2 for mounting the seasoning relay plate on the main pipe 11 , and the frame plate assembly is composed of a cover plate 6 and a pressing plate 51 .

[0044] The cover plate 6 is provided with a screw hole 61 for fixing the cover plate 6 on the main pipe 11, a mounting seat 62 for the drive motor 4, a gear through hole 63 and a through hole 64 for the limit switch 5. The drive motor 4 is fixedly mounted on the mounting seat 62, and the gear 3 in the transmission mechanism is meshed with the rack 21 on the seasoning relay plate 2 through the gear through hole 63. The cover plate 6 is mounted on the mounting and fixing position of the frame plate assembly of the seasoning conveying pipe 1 by screws or bolts, and a receiving cavity is formed therebetween, and the seasoning relay plate 2 is placed in the receiving cavity.

[0045] The pressing plate 51 is used to fix the limit switch 5 . The limit switch 5 is fixed to the pressing plate 51 . The pressing plate 51 is fixed to the lower surface of the cover plate 6 , so that the limit switch 5 passes through the through hole 64 and is placed on one side of the accommodating track 13 .

[0046] The protective cover 8 of the driving motor 4 is fixedly connected to the mounting seat 62 on the frame plate assembly by screws or bolts, so that the driving motor 4 is fixed in the motor mounting seat 62 .

[0047] Combination Figure 4 and Figure 5As shown, the gear 3 is sleeved on the front end of the output shaft of the driving motor 4. The gear 3 is a cylindrical gear, and the gear 3 is meshed with the rack 21 on the seasoning relay plate 2. The driving motor 4 drives the gear 3 to rotate forward or reverse, and the gear 3 drives the seasoning relay plate 2 to move back and forth in a straight line.

[0048] In order to save the overall installation space, the driving motor 4 is a micro motor, and the limit switch 5 is an ultra-small micro switch. The two micro switches are arranged on the same side of the accommodating track 13 of the seasoning relay plate 2, and the two micro switches are installed on the pressure plate 51. The relative distance between the two micro switches determines the movable distance of the seasoning relay plate 2.

[0049] Correspondingly, two oblique openings cooperating with the micro switches are provided on the rack 21 of the seasoning relay plate 2, and the oblique openings increase the movable travel of the seasoning relay plate 2 within a limited space.

[0050] like Figure 2 As shown, a pressure wheel 7 is arranged between the lower surface of the seasoning relay plate 2 and the cover plate 6, and the wheel axle of the pressure wheel 7 is mounted on the pressure wheel mounting positions 14 extending downwardly on both sides of the lower surface of the main pipe 11. The wheel surface of the pressure wheel 7 is pressed against the lower surface of the seasoning relay plate 2. The pressure wheel 7 is used to prevent the front part of the seasoning relay plate 2 from tilting downward due to gravity, and ensure that the seasoning relay plate 2 moves linearly close to the main pipe 11, so that the seasoning can flow into the seasoning relay plate 2 smoothly.

[0051] The working process of the seasoning injection assembly 100 corresponding to the transmission mechanism is as follows:

[0052] Combination Figure 4 and Fig. 9 As shown, when the cooking machine control center does not issue a command to add seasoning, and the frying pan 300 is in any position not covered with the pot cover 200, the seasoning injection assembly 100 is in the original position. At this time, the micro motor is in a waiting state for instructions, the gear 3 is located at the front end of the rack 21, and the micro switch away from the outlet of the main pipe 11 is in a closed state.

[0053] Combination Figure 5 and Fig.10 As shown, when the cooking machine control center issues an instruction to add seasoning, the wok 300 rotates to close with the pot cover 200, and the lifting mechanism drives the wok 300 to move toward the pot cover 200. At this time, the drive motor 4 rotates forward, the drive gear 3 rotates, and the gear 3 drives the seasoning relay plate 2 to move forward. When the seasoning relay plate 2 moves and contacts the micro switch near the outlet of the main pipe 11, the micro switch is closed, the drive motor 4 stops rotating, and the seasoning relay plate 2 reaches the working position. When the wok 300 moves to close with the pot cover 200, the seasoning to be added flows from the branch pipe 12 into the main pipe 11, then flows into the seasoning relay plate 2, and finally falls on the food in the wok 300, completing the seasoning adding step of the cooking machine.

[0054] After the seasoning addition instruction is completed, the driving motor 4 reverses, and the driving gear 3 drives the seasoning relay plate 2 to move backward. When the seasoning relay plate 2 moves and touches the micro switch away from the outlet of the main pipe 11, when the micro switch is closed, the driving motor 4 stops rotating, and the seasoning relay plate 2 returns to its original position.

[0055] (2) Screw drive mechanism

[0056] like Figure 6 As shown, the seasoning relay plate 2 corresponding to the transmission mechanism is: a downwardly extending protrusion 22 is provided at the rear end of the lower surface of the seasoning relay plate 2, and an internal threaded hole that can penetrate the protrusion 22 and is arranged along the length direction of the seasoning relay plate 2 is provided in the protrusion 22.

[0057] Combination Figures 6 to 8 As shown, the drive motor 4 is fixedly connected to the motor mounting position 15 on the rear end surface of the main pipe 11, and the output shaft of the drive motor 4 is fixedly connected to the rear end of the screw rod 31 through a coupling 41, and the front end of the screw rod 31 is placed in the internal threaded hole in a spiral connection manner.

[0058] The driving motor 4 can directly drive the screw rod 31 to rotate, and the screw rod 31 drives the seasoning relay plate 2 to perform linear reciprocating movement.

[0059] Combination Figure 7 and Figure 8 As shown, two limit switches 5 are arranged at the front and rear ends of the same side of the accommodating track 13 of the seasoning relay plate 2, and the limit switches 5 are installed on a pressing plate 51, and the pressing plate 51 is fixedly connected to the main pipe 11. Preferably, in order to save installation space, the limit switches 5 are ultra-small micro switches.

[0060] A limit frame 17 is provided on the lower surface of the front end of the main pipe 11, and the front end of the seasoning relay plate 2 passes through the limit frame 17. The limit frame 17 is used to prevent the front part of the seasoning relay plate 2 from tilting downward due to gravity, and ensure that the seasoning relay plate 2 moves in a straight line close to the main pipe 11, so that the seasoning can flow smoothly into the seasoning relay plate 2.

[0061] In order to make the seasoning relay plate more stable when moving and to extend the service life of the transmission mechanism, preferably, the transmission mechanism uses a ball screw transmission mechanism.
