Description

Technical Field

[0001] The present invention relates to the technical field of cooking equipment, and in particular to an inner pot structure of a steam-bake all-in-one machine. Background Art

[0002] The hot air blower baffle of an existing ordinary oven is generally fixed to the front side of the rear cover of the inner pot by screws, such as the "Air Guide Structure of an Electric Oven" disclosed in the Chinese Utility Model Patent No. 201721288964.6 (Authorization Announcement No. CN 208228850 U). The air guide structure includes a hot air blower baffle, blades, a driving mechanism and a controller. The hot air blower baffle is tightly attached to the inner wall of the oven inner pot shell on all sides. An air outlet is opened on the hot air blower baffle. The blades are rotatably connected to the hot air blower baffle and are located on one side of the air outlet. The driving mechanism is electrically connected to the controller. The driving mechanism can drive the blades to rotate under the control of the controller to open and close the air outlet. Another example is the "A Steamer and Oven All-in-One" disclosed in the Chinese utility model patent with patent number 201721875797.5 (authorization announcement number CN208582202 U), in which the hot air blower baffle and the hot air blower are arranged inside the lower inner tank and close to the back plate of the inner tank, and a hot air chamber is formed between the hot air blower baffle and the lower inner tank back plate, and the inner tank is connected to the hot air chamber through the air inlet and air outlet on the hot air blower baffle. For a steamer and oven all-in-one, if the hot air blower baffle is arranged inside the inner tank, then the connection between the hot air blower baffle and the back cover of the inner tank will be in the microwave energy field. At this time, if the hot air blower baffle and the back cover of the inner tank produce a small gap, sparks will be generated between the hot air blower baffle and the back cover of the inner tank. In addition, in order to avoid steam leakage, the hot air blower baffle and the back cover of the inner tank need to be connected through a sealing ring, but because the sealing ring is in a high-temperature baking environment for a long time, it will age and crack. In summary, the inner pot structure of the existing all-in-one steam-and-bake machine needs to be further improved. Summary of the invention

[0003] The first technical problem to be solved by the present invention is to provide an inner pot structure of a steam-bake micro-integrated machine which can avoid microwave ignition and microwave leakage in view of the current status of the prior art.

[0004] The second technical problem to be solved by the present invention is to provide an inner pot structure of a steam-bake micro-in-one machine capable of water-cooling a sealing ring in view of the current status of the prior art.

[0005] The technical solution adopted by the present invention to solve the first technical problem mentioned above is: the inner pot structure of the steam-bake micro-in-one machine includes an inner pot barrel body and a back plate installed at the rear of the inner pot barrel body, and is characterized in that: a hot air blower baffle is installed on the rear side of the back plate, a hot air chamber is formed between the hot air blower baffle and the back plate, a through hole that can prevent microwaves from passing through is opened in the area of ​​the back plate corresponding to the hot air chamber, and the periphery of the hot air blower baffle and the back plate are sealed by a sealing ring.

[0006] The technical solution adopted by the present invention to solve the above-mentioned second technical problem is: an annular installation cavity is formed between the periphery of the hot air blower baffle and the back plate, the sealing ring is installed in the annular installation cavity, and an annular water flow channel arranged along the circumference of the sealing ring is formed in the annular installation cavity.

[0007] Preferably, the area other than the periphery of the hot air blower baffle is recessed backwards to form the hot air chamber between the baffle and the back plate, the outer edge of the periphery of the hot air blower baffle is bent toward the back plate to form a baffle, and the baffle is abutted against the back plate to form the annular mounting cavity between the periphery of the hot air blower baffle and the back plate.

[0008] In order to improve the water cooling effect of the sealing ring, the inner and outer edges of the front and rear sides of the sealing ring are provided with a front sealing rib extending forward and a rear sealing rib extending backward. The front sealing rib abuts against the back plate to form a front annular water flow channel between the back plate and the sealing ring, and the rear sealing rib abuts against the periphery to form a rear annular water flow channel between the hot air blower baffle and the sealing ring. The sealing ring is provided with a water hole, and the front annular water flow channel and the rear annular water flow channel are interconnected through the water hole.

[0009] In order to allow the water flowing out of the water pump to flow into the inner tank through the annular water flow channel, a water inlet and a water outlet are opened on the periphery of the hot air blower baffle, the water inlet is connected with the water outlet through the annular water flow channel, and the water inlet is connected with the water outlet of the water pump outside the inner tank through a water inlet pipe, and the water outlet is connected with the inside of the inner tank through a water outlet pipe.

[0010] In order to allow the cooling water to fill the entire sealing ring area, the water inlet is arranged on the lower periphery of the hot air blower baffle, and the water outlet is arranged on the upper periphery of the hot air blower baffle.

[0011] In order to facilitate the maintenance and replacement of the hot air blower and the back heating pipe, the hot air blower baffle is detachably connected to the back plate of the inner tank.

[0012] The hot air blower baffle can have a variety of detachable connection structures. Preferably, a first mounting hole is opened on the periphery of the hot air blower baffle, and a second mounting hole is opened at the corresponding position of the sealing ring. Correspondingly, a stud extending backward is provided on the back plate of the inner tank, and the stud passes through the second mounting hole and the first mounting hole in turn and is fixed by a nut.

[0013] Preferably, a microwave generating device is installed above the inner pot.

[0014] As a preferred embodiment of any of the above solutions, a hot air blower and a heating pipe are installed in the hot air chamber, so that the hot air blower can transfer the heat generated by the heating pipe to the inside of the inner tank through the through holes on the back plate of the inner tank.

[0015] Compared with the prior art, the advantages of the present invention are: the inner pot structure of the steam-bake micro-in-one machine installs the hot air blower baffle on the rear side of the inner pot back plate, so that the matching point of the hot air blower baffle and the back plate is located outside the microwave energy field, thereby avoiding sparks; in addition, by forming an annular water flow channel arranged along the circumference of the sealing ring in the annular installation cavity between the periphery of the hot air blower baffle and the back plate, the sealing ring can be cooled by water cooling, thereby effectively avoiding aging and cracking of the sealing ring and ensuring that the sealing ring can be used for a long time.

[0024] The present invention is further described in detail below with reference to the accompanying drawings.

[0025] like Figures 1 to 5 As shown, the inner pot structure of the steam-bake micro-integrated machine of this embodiment includes an inner pot barrel body 1 and a back plate 2 installed at the rear of the inner pot barrel body 1, and a hot air blower baffle 3 is installed on the rear side of the back plate 2, and the hot air blower baffle 3 is recessed backward to form a hot air chamber 4 between the back plate 2. A through hole 21 is opened in the area corresponding to the hot air chamber on the back plate 2, and a hot air blower 14 and a heating pipe 15 are installed in the hot air chamber 4, wherein the middle through hole 21 is an air inlet hole, and the surrounding through holes 21 are air outlet holes. In the grilling mode, the air in the hot air chamber 4 is heated by the heating pipe 15, and then circulates between the inner pot cavity and the hot air chamber 4 through the air inlet hole and the air outlet hole under the action of the hot air blower 14, thereby heating the food in the inner pot.

[0026] The microwave generating device 13 of this embodiment is installed above the inner pot, and the microwaves generated by the microwave generating device 13 heat the food in the inner pot. The through hole of this embodiment is designed as a small round hole, and the aperture of the small round hole is designed to prevent the microwaves from passing through, thereby preventing the microwaves in the inner pot from entering the hot air chamber 4. In addition, the hot air blower baffle 3 is arranged on the rear side of the inner pot back plate 2, that is, the hot air blower baffle 3 is placed outside the microwave energy field, which solves the microwave ignition problem between the hot air blower baffle 3 and the inner pot back plate 2.

[0027] The integrated machine has a steam heating function, so steam sealing is required between the hot air blower baffle 3 and the back plate 2. Figure 6 and Figure 7 As shown, the periphery of the hot air blower baffle 3 is sealed with the back plate 2 via a sealing ring 5, and the periphery outer edge of the hot air blower baffle 3 is bent toward the back plate 2 to form a retaining edge, and the retaining edge 32 abuts against the back plate 2 to form the annular mounting cavity 6 between the periphery 31 of the hot air blower baffle 3 and the back plate 2, and the sealing ring 5 is installed in the annular mounting cavity 6.

[0028] The all-in-one machine also has a grilling function. The sealing ring is in a high temperature environment for a long time and is prone to aging and cracking. Therefore, a cooling water system is designed in this embodiment. Specifically, an annular water flow channel arranged along the circumference of the sealing ring 5 is formed in the annular installation cavity 6. By injecting cold water into the annular water flow channel, the sealing ring 5 can be cooled.

[0029] Combination Figure 8As shown, the inner and outer edges of the front and rear sides of the sealing ring 5 are provided with a front sealing rib 51 extending forward and a rear sealing rib 52 extending backward. The front sealing rib 51 abuts against the back plate 2 to form a front annular water flow channel 71 between the back plate 2 and the sealing ring 5. The rear sealing rib 52 abuts against the periphery 31 to form a rear annular water flow channel 72 between the hot air blower baffle 3 and the sealing ring 5. The sealing ring 5 is provided with a water hole 53. The front annular water flow channel 71 and the rear annular water flow channel 72 are connected to each other through the water hole 53. The periphery 31 of the hot air blower baffle 3 is provided with a water inlet 33 and a water outlet 34. The water inlet 33 is connected to the water outlet 34 through the annular water flow channel. The water inlet 33 is connected to the water outlet of the water pump 8 outside the inner tank through the water inlet pipe 9, and the water outlet 34 is connected to the inside of the inner tank through the water outlet pipe 10. Furthermore, in order to allow the cooling water to fill the entire sealing ring area, the water inlet 33 is arranged on the lower periphery of the hot air blower baffle 3, and the water outlet 34 is arranged on the upper periphery of the hot air blower baffle 3. During operation, the water in the integrated machine water tank (not shown) is injected into the annular water flow channel through the water inlet pipe 9 and the water inlet 33 in turn under the suction action of the water pump 8. The cooling water flows through the front annular water flow channel 71 and the rear annular water flow channel 72, and then flows out from the water outlet 34 to the water outlet pipe 10, and then flows into the inner tank. The front sealing rib 51 and the rear sealing rib 52 of the sealing ring can prevent water from leaking. In addition, after the annular water flow channel is formed along the sealing ring, in addition to cooling the sealing ring, it can also prevent the steam in the inner tank from leaking.

[0030] The hot air blower baffle 3 of this embodiment is detachably connected to the back plate 2, and the specific structure is as follows: a first mounting hole 35 is opened on the periphery 31 of the hot air blower baffle 3, and a second mounting hole 54 is opened at the position of the sealing ring 5. Correspondingly, a stud is welded on the back plate 2 of the inner tank, and the stud 11 passes through the second mounting hole 54 and the first mounting hole 35 in sequence and is connected and fixed by a nut 12. After adopting the above-mentioned detachable connection structure, it is convenient to repair and replace the hot air blower 14 and the heating pipe 15.
