[0042] In addition, an electric heating device 34 is further provided at the bottom of the inner container 2, which heats the bottom of the cavity of the inner container 2 to further achieve all-round heating.

[0043] The present invention adopts a double hot air structure to ensure uniform temperature distribution in the inner container, and further ensures that the food materials in the inner container can be evenly heated, realizing all-round three-dimensional heating in the true sense. And when the rotation directions of the two circulation fans are opposite, it further ensures uniform temperature distribution in the inner container.

[0046] The fixing cover 36 of the circulating motor shaft seal ring is used for fixing the circulating motor shaft seal ring 35. The fixing cover 36 of the circulating motor shaft seal ring is arranged in the circulating air chamber 22 and installed on the chamber wall of the inner tank 2 cavity. A shaft hole 361 of the fixing cover of the circulating motor shaft seal ring is provided on the fixing cover 36 of the circulating motor shaft seal ring for the circulating motor shaft 32 to pass through. The shaft hole 361 of the fixing cover of the circulating motor shaft seal ring extends towards the circulating motor shaft seal ring 35 to form a stop portion 362 of the shaft hole of the fixing cover of the circulating motor shaft seal ring. After the fixing cover 36 of the circulating motor shaft seal ring is installed on the inner tank 2, the stop portion 362 of the shaft hole of the fixing cover of the circulating motor shaft seal ring abuts against the flanging 351 of the circulating motor shaft seal ring to fix the circulating motor shaft seal ring 35.

[0047] An annular protrusion 353 of the circulating motor shaft seal ring is provided on the inner wall of the circulating motor shaft seal ring 35, and its thickness is less than 1.0 mm. The protrusion 353 of the circulating motor shaft seal ring is in interference fit with the circulating motor shaft 32, and the interference amount between the two is less than 0.3 mm. During installation, first sleeve the circulating motor shaft seal ring 35 on the circulating motor shaft 32, then install the circulating motor shaft seal ring 35 on the inner tank 2, and finally install the fixing cover 36 of the circulating motor shaft seal ring on the inner tank 2. Installing in the above step sequence can ensure that the circulating motor shaft seal ring 35 and the circulating motor shaft 32 are concentrically installed and can better seal.

[0048] The circulating motor shaft seal ring of the present invention fully ensures the sealing effect under the fixation of the fixing cover of the circulating motor shaft seal ring.

The turning fork 4 is rotatably arranged on the turning fork bracket 41, and the turning fork bracket 41 can be movably placed on the bracket 14.

[0050] The turning fork 4 is driven to rotate by a turning fork motor 42. Specifically, the turning fork motor 42 is arranged at the geometric center of the rear part of the inner liner 2 and is located between two groups of circulation blowers. A turning fork connecting shaft 421 is provided on the motor shaft of the turning fork motor 42. A turning fork connecting shaft hole is provided on the rear part of the inner liner 2, and the turning fork connecting shaft 421 extends into the cavity of the inner liner 2 through the turning fork connecting shaft hole. A cover plate through hole 213 corresponding to the turning fork 4 is provided on the inner liner cover plate 21. One end of the turning fork 4 can pass through the cover plate through hole 213 and be connected to the turning fork connecting shaft 421. The turning fork motor 42 drives the turning fork connecting shaft 421 to rotate, and the rotation of the turning fork connecting shaft 421 drives the turning fork 4 to rotate.

[0051] As Figure 6 shown, the present invention further provides a rotating device sealing structure, which is used for sealing between the turning fork connecting shaft 421 and the inner liner 2. The rotating device sealing structure includes a turning fork connecting shaft sealing ring 43 and a turning fork connecting shaft sealing ring fixing cover 44.

[0052] The turning fork connecting shaft sealing ring 43 is installed on the turning fork connecting shaft hole and sleeved on the turning fork connecting shaft 421. Specifically, the opening of the turning fork connecting shaft sealing ring 43 facing the turning fork motor 42 extends in the direction of the turning fork motor 42 and then bends to form a turning fork connecting shaft sealing ring flange 431, and a turning fork connecting shaft sealing ring fixing groove 432 is formed between the turning fork connecting shaft sealing ring flange 431 and the end face of the corresponding turning fork connecting shaft sealing ring 43. A turning fork connecting shaft hole flange 251 is provided on the opening of the turning fork connecting shaft hole, and the turning fork connecting shaft sealing ring fixing groove 432 is sleeved on the turning fork connecting shaft hole flange 251.

[0053] The turning fork connecting shaft sealing ring fixing cover 44 is used for fixing the turning fork connecting shaft sealing ring 43.

A turning fork connecting shaft sealing ring fixing cover shaft hole 441 is provided on the turning fork connecting shaft sealing ring fixing cover 44 for the turning fork connecting shaft 421 to pass through. The turning fork connecting shaft sealing ring fixing cover shaft hole 441 extends in the direction of the turning fork connecting shaft sealing ring 43 to form a turning fork connecting shaft sealing ring fixing cover shaft hole stop portion 442. After the turning fork connecting shaft sealing ring fixing cover 44 is installed on the inner liner 2, the turning fork connecting shaft sealing ring fixing cover shaft hole stop portion 442 is inserted into the opening of the turning fork connecting shaft sealing ring 43, and the inner cavity of the turning fork connecting shaft sealing ring fixing cover 44 presses the turning fork connecting shaft sealing ring 43 against the cavity wall of the cavity of the inner liner 2 to realize the fixation of the turning fork connecting shaft sealing ring 43.

[0054] An annular fork connection shaft seal ring protrusion 433 is provided on the inner wall of the fork connection shaft seal ring 43, and the fork connection shaft seal ring protrusion 433 is in interference fit with the fork connection shaft 421.

[0055] The fork connection shaft seal ring of the present invention fully ensures the sealing effect under the fixation of the fork connection shaft seal ring fixing cover. The setting of the fork connection shaft seal ring protrusion not only ensures sealing but also does not affect the rotation of the fork connection shaft.

[0056] See Figures 7-11 , the steam mechanism includes an evaporator 5 and evaporator pipelines. The evaporator 5 is communicated with the cavities of the water tank 12 and the inner container 2 through the evaporator pipelines. Among them, the evaporator 5 includes an evaporator base 51, an evaporator cover 52, a heating plate 53, and a water vapor separation member 6. The evaporator base 51 is made of a metal material, and the evaporator cover 52 is made of a high-temperature resistant plastic material.

[0057] An evaporator support 13 is provided at the top of the inner container 1, and the evaporator 5 is installed on the evaporator support 13. Specifically, the evaporator base 51 is installed on the heating plate 53, the evaporator cover 52 is installed on the evaporator base 51 by screws, and an evaporator seal ring 56 is provided at the connection between the evaporator cover 52 and the evaporator base 51. The heating plate 53 is installed on the evaporator support 13, and a thermal cut-off 54 and a thermostat 55 are provided at its bottom. Among them, reinforcing ribs are provided on the cavity wall of the cover cavity 521 of the evaporator cover 52 to increase the overall structural strength.

[0058] The cover cavity 521 of the evaporator cover 52 is communicated with the seat cavity 511 of the evaporator base 51 and together forms a steam generation cavity. An evaporator water inlet / outlet 512 communicated with the seat cavity 511 is provided at the bottom of the evaporator base 51, and evaporator steam outlets 522 communicated with the cover cavity 521 are respectively provided at the two high positions on both sides of the evaporator cover 52. The evaporator pipelines include a water inlet pipeline and a steam pipeline. The evaporator water inlet / outlet 512 is communicated with the water tank 12 through the water inlet pipeline, and the evaporator steam outlet 522 is communicated with the cavity of the inner container 2 through the steam pipeline.

[0059] Among them, inner container steam inlets are respectively provided on the left and right sides of the inner container 2, and the evaporator steam outlets 522 are in one-to-one correspondence and communication with the inner container steam inlets. During operation, the steam generated by the evaporator 5 enters the cavity of the inner container 2 from both sides. The present invention comprehensively considers the layout of the steam pipelines, ensures uniform steam distribution in the inner container during operation, and at the same time ensures uniform temperature distribution in the inner container, so that the food materials in the inner container are fully and evenly heated.

[0060] The water vapor separation member 6 is arranged between the evaporator cover 52 and the evaporator base 51. Specifically, the water vapor separation member 6 is symmetrically arranged in the cover cavity 521 near the evaporator steam outlet 522, and respectively divides the two sides of the cover cavity 521 into a first condensation cavity 65 and a second condensation cavity 66.

[0061] As shown Figure 9 in the figure, the water vapor separation member 6 is integrally formed and includes a bottom surface portion 61, two side surface portions 62, an end plate portion 63, and a partition portion 64. The bottom surface portion 61 is disposed between the two side surface portions 62. The end plate portion 63 is disposed at one end of the bottom surface portion 61 and its two ends are respectively connected to the side surface portions 62. The partition portion 64 is disposed in the middle of the bottom surface portion 61 and its two ends are respectively connected to the side surface portions 62. Among them, the bottom surface portion 61 is an inclined surface and its higher end is away from the evaporator steam outlet 522. The end plate portion 63 is disposed on the higher end of the bottom surface portion 61 and there is a gap between it and the bottom of the cover cavity 521. The side surface portions 62 and the partition portion 64 can both abut against the bottom of the cover cavity 521. The side surface portions 62 are provided with clearances to avoid the reinforcing ribs.

[0062] The first condensation cavity 65 is jointly surrounded by the bottom surface portion 61, the side surface portions 62, the end plate portion 63, and the partition portion 64. The vacant position between the end plate portion 63 and the bottom of the cover cavity 521 forms a first communication port 631 to communicate the cover cavity 521 with the first condensation cavity 65. The second condensation cavity 66 is jointly surrounded by the bottom surface portion 61, the partition portion 64, and the cavity wall of the cover cavity 521, and the second condensation cavity 66 is communicated with the evaporator steam outlet 522. The bottom of the partition portion 64 is provided with a second communication port 641 to communicate the first condensation cavity 65 with the second condensation cavity 66. The lower end of the bottom surface portion 61 is provided with a drain hole 611 to communicate the second condensation cavity 66 with the cover cavity 521.

[0063] Refer to Figure 10 the figure, and the arrows in the figure indicate the flow direction of the steam. When the steam mechanism works, the water tank 12 adds water into the evaporator base 51, and the water in the evaporator base 51 is heated by the heating plate 53 to generate steam. The steam rises along the bottom surface portion 61. During this process, part of the moisture in the steam will condense on the surface of the bottom surface portion 61 and fall back into the seat cavity 511 along the inclined surface. Then, the steam enters the first condensation cavity 65 through the first communication port 631 and enters the second condensation cavity 66 through the second communication port 641, and then rises and is discharged through the evaporator steam outlet 522. During this process, most of the remaining moisture in the steam will condense on the cavity walls of the first condensation cavity 65 and the second condensation cavity 66. The moisture condensed on the cavity wall of the first condensation cavity 65 flows into the second condensation cavity 66 along the inclined surface and flows back into the seat cavity 511 together with the moisture condensed on the cavity wall of the second condensation cavity 66 through the drain hole 611. In this way, water vapor separation is achieved, and the moisture in the steam is effectively reduced.

[0064] In addition, a reinforcing rib plate 67 is further provided in the second condensation cavity 66, which can not only strengthen the overall structure of the water vapor separation member 6, but also condense the moisture in the steam, further reducing the moisture in the steam.

[0065] The side surfaces 62 of the water vapor separation member 6 are respectively provided with locking holes 68, and the cavity walls of the cover cavity 521 are respectively provided with locking blocks corresponding to the locking holes 68. The water vapor separation member 6 is installed in the cover cavity 521 by the engagement of the locking holes 68 and the locking blocks. Further, slots 681 are respectively provided on both sides of the side surface 62 close to the locking holes 68 to form two elastic arms provided with the locking holes 68, so that the water vapor separation member 6 can be easily installed. In addition, the water vapor separation member 6 is further provided with a reinforcement fastener 69, which is arranged at the lower end of the bottom surface 61, and a reinforcement locking hole 691 is arranged on the side wall of the evaporator cover 52. The water vapor separation member 6 can be firmly installed in the cover cavity 521 by the engagement of the reinforcement fastener 69 and the reinforcement locking hole 691.

[0066] See Figure 7 、 11 , the evaporator pipeline further includes a drainage pipeline, and the evaporator water inlet and outlet 512 is communicated with the cavity of the inner tank 2 through the drainage pipeline.

[0067] Specifically, the evaporator water inlet and outlet 512 is communicated with the first end of the three-way pipe 7 through the inlet and outlet pipe of the evaporator 5. The second end of the three-way pipe 7 is communicated with the water tank 12 through the water tank outlet pipe 72, and the third end is communicated with the cavity of the inner tank 2 through the evaporator drain pipe 73.

[0068] A first solenoid valve 721 driven by the main controller is provided on the water tank outlet pipe 72 to control the on-off between the water tank 12 and the evaporator 5; a second solenoid valve 731 driven by the main controller is provided on the evaporator drain pipe 73 to control the on-off between the evaporator 5 and the cavity of the inner tank 2.

[0069] The water inlet process of the evaporator 5 is as follows: the main controller drives the first solenoid valve 721 to open so that the water tank 12 is communicated with the evaporator water inlet and outlet 512, and the water in the water tank 12 enters the evaporator 5 quantitatively, and then the main controller drives the first solenoid valve 721 to close.

[0070] The drainage process of the evaporator 5 is as follows: after the work is completed, the main controller drives the second solenoid valve 731 to open so that the evaporator water inlet and outlet 512 is communicated with the cavity of the inner tank 2, and the water in the evaporator 5 flows into the cavity of the inner tank 2, and then the main controller drives the second solenoid valve 731 to close; the water flowing into the cavity of the inner tank 2 will be evaporated by the heating mechanism.

[0071] The evaporator of the present invention has a drainage function, which avoids the accumulation of water in the evaporator, thereby preventing the generation of scale in the evaporator; in addition, the evaporator water inlet and the evaporator drain outlet are integrated into one evaporator water inlet and outlet, reducing the connection links and reducing the probability of steam leakage and water leakage.

[0072] See Figures 12-15, the exhaust mechanism includes an exhaust fan assembly 8, an exhaust passage 81, and a communication passage 813. The air outlet end of the exhaust fan assembly 8 communicates with the air inlet end of the exhaust passage 81. The air outlet end of the exhaust passage 81 is disposed on the front side of the cabinet 1. The communication passage 813 communicates the cavity of the inner container 2 with the exhaust passage 81.

[0073] At the top of the inner container 2, there is provided an exhaust passage bottom plate 811. On the exhaust passage bottom plate 811, there is provided a fan-shaped exhaust passage cover 812. The exhaust passage 81 is formed by the cavity between the exhaust passage cover 812 and the exhaust passage bottom plate. The exhaust fan assembly 8 is disposed on the top of the inner container 2, and its air outlet end is connected to the air inlet of the exhaust passage cover 812.

[0074] The steam in the inner container 2 can enter the exhaust passage 81 through the communication passage 813. When the exhaust fan assembly 8 operates, it generates an air flow. The flowing air flow drives the steam in the exhaust passage 81 to flow towards the air outlet end of the exhaust passage 81 and be discharged to the outside, thereby realizing exhaust. The air inlet end of the exhaust fan assembly 8 communicates with the cavity between the top of the inner container 2 and the cabinet 1. When the exhaust fan assembly 8 operates, it can also discharge the heat generated during the operation of the components disposed in the cavity between the top of the inner container 2 and the cabinet 1.

[0075] See Figure 11 , 15 -18, the lighting mechanism includes an LED lamp assembly 9, a lamp post fixing sleeve 91, a lamp post 92, and a lamp shade 93. The exhaust passage bottom plate is symmetrically provided with bottom plate through holes 8111. At the corresponding positions of the bottom plate through holes 8111 on the top of the inner container 2, there are provided inner container through holes 26. The bottom plate through holes 8111 communicate with the inner container through holes 26. Among them, the edge of the inner container through hole 26 extends towards the cabinet 1 to form a through hole blocking portion 261. The LED lamp assembly 9 is connected to the lamp post fixing sleeve 91 and is disposed on the bottom plate through hole 8111. The lamp post 92 is disposed on the lamp post fixing sleeve 91 and extends into the inner container 2 through the bottom plate through hole 8111 and the inner container through hole 26. The lamp shade 93 is disposed on the inner container through hole 26 and surrounds the lamp post 92.

[0076] Specifically, the lamp shade 93 is in the shape of a semi-ellipsoid with one end open. On the side near the opening, there is provided a lamp shade mounting portion 931 surrounding it. The lamp shade 93 extends into the inner container 2 through the inner container through hole 26. The lamp shade mounting portion 931 abuts against the through hole blocking portion 261 and seals the inner container through hole 26.

[0077] The lamp post fixing sleeve 91 includes a fixing sleeve mounting portion 911 in the shape of a gasket and a fixing sleeve sleeving portion 912 in the shape of a cylinder. The fixing sleeve sleeving portion 912 is vertically disposed on the fixing sleeve mounting portion 911. The fixing sleeve mounting portion 911 is provided with a fixing sleeve through hole 913 communicating with the fixing sleeve sleeving portion 912, and the diameter of the fixing sleeve through hole 913 is smaller than the diameter of the fixing sleeve sleeving portion 912.

[0078] The lamp post 92 is cylindrical, and the fixing sleeve sleeving part 912 is sleeved on the top of the lamp post 92. After the LED lamp assembly 9 is connected to the fixing sleeve mounting part 911, it is installed at the corresponding bottom plate through hole 8111 of the exhaust passage bottom plate 811. The lamp beads of the LED lamp assembly 9 extend into the fixing sleeve through hole 913. The fixing sleeve sleeving part 912 passes through the bottom plate through hole 8111, and the lamp post 92 extends into the lamp cover 93 through the bottom plate through hole 8111 and the inner liner through hole 26.

[0079] Further, a chamfer 94 is provided at the bottom of the lamp post 92. The light emitted by the LED lamp assembly 9 is transmitted through the lamp post 92, and the chamfer 94 enables the light energy to be evenly transmitted in all directions.

[0080] The present invention abandons the traditional halogen lamp and adopts the LED lamp assembly, which has the advantages of high brightness, energy saving, low heat energy, etc. The light emitted by the LED lamp assembly is transmitted through the lamp post, and a chamfer is provided at the bottom of the lamp post to enable the light energy to be evenly transmitted. In addition, the lamp cover plays a role of isolation and temperature reduction. It not only seals the inner liner through hole to prevent steam and heat from being discharged to the top of the inner liner through the inner liner through hole, affecting the performance of electrical components, but also isolates the heat of the inner liner to prevent the lighting mechanism from being overheated and affecting the performance.

[0081] In addition, referring to Figure 11 、 12 , the air inlet end of the exhaust passage is narrower than the air outlet end of the exhaust fan assembly 8, that is, gaps are respectively left between the two ends of the air inlet of the exhaust passage cover 812 and the two ends of the air outlet end of the exhaust fan assembly 8 to form a heat dissipation air outlet 95, thereby constituting an LED lamp heat dissipation device. After a part of the air flow generated by the exhaust fan assembly 8 is discharged through the heat dissipation air outlet 95, it is discharged along the two outer sides of the exhaust passage cover 812.

[0082] The LED lamp assembly 9 of the lighting mechanism is arranged on the exhaust passage bottom plate 811, and it is located on the two outer sides of the exhaust passage cover 812; rib plates 814 for strengthening the overall structure are respectively arranged on the outer sides of the exhaust passage cover 812, and the rib plates 814 are inclined towards the LED lamp assembly 9, so that the air flow discharged through the heat dissipation air outlet 95 flows along the rib plates 814 towards the LED lamp assembly 9. When the exhaust fan assembly 8 operates, an air flow is generated, and the flowing air flow will take away the heat generated when the LED lamp assembly 9 works, thereby realizing the heat dissipation of the LED lamp assembly 9.

The scope of the present invention is defined by the claims and their equivalent substitutions. Improvements made without creative labor should be included within the protection scope of the present invention.
