Description

Technical Field

[0001] The utility model relates to the technical field of drying equipment, in particular to an oven liner. Background Art

[0002] An oven is a commonly used baking equipment, which is usually needed to dry products during the production and processing process. There are two types of ovens: forced air drying and vacuum drying. Forced air drying uses a circulating fan to blow out hot air to ensure the temperature balance in the oven. Vacuum drying uses a vacuum pump to extract the air in the oven, making the atmospheric pressure in the oven lower than normal pressure, so that the product can be tested in a very clean state. It is a commonly used instrument and equipment, mainly used to dry samples, and can also provide the temperature environment required for the experiment.

[0003] Because forced-air drying ovens require hot air to circulate within the oven, dust generated during the production process can adhere to the fan blades, the oven liner, or the air outlet as the circulating fan drives the oven. While the fan blades and air outlet are typically detachable for easy cleaning, the oven liner is typically fixed in place, making cleaning more difficult. Therefore, the existing technology needs improvement. Utility Model Content

Therefore, the directional words do not constitute an absolute limitation on the characteristics of the features and the relationship between the features in space, but only play a relative limitation role.

[0028] like Figures 1 to 9As shown, the utility model provides an oven liner, including an inner liner body 1, the inner liner body 1 includes a connected air chamber 10 and an air inlet 15, a multi-component guide plate 3 is provided on the side of the inner liner body 1 away from the air inlet 15, and an air outlet 14 is left between the multi-component guide plates 3; a locking assembly 2 is also provided in the inner liner body 1, the locking assembly 2 includes a slide rod 20, a locking block 21, a locking ring 24 and a reset elastic member 22, the slide rod 20 is mounted on the air chamber 10 through a sliding bearing In the chamber 10, the locking block 21 is installed on the slide rod 20 and the locking block 21 can slide on the slide rod 20. A stopper 23 for limiting the sliding of the locking block 21 is also provided on the slide rod 20. The reset elastic member 22 is sleeved on the slide rod 20, and the reset elastic member 22 can press the locking block 21 against the stopper 23; the locking ring 24 is fixedly connected to the guide plate 3, and a lock buckle 210 is provided on the locking block 21, and a lock hole 240 corresponding to the lock buckle 210 is provided on the locking ring 24.

[0029] In this embodiment, side baffles 12 and heat insulation plates 13 are provided on both sides of the inner tank body 1. The heat insulation plates 13 separate the air chamber 10 into a hot air portion and a heat insulation portion 11. The heat insulation portion 11 is located between the side baffles 12 and the heat insulation plates 13. A set of locking components 2 are installed in the heat insulation portions 11 on both sides.

[0030] In this embodiment, an installation component 4 is provided on the side baffle 12, and the installation component 4 includes a socket 41 and a mounting seat 40. The socket 41 is fixedly installed on the side baffle 12, and the mounting seat 40 is fixedly installed in the oven, and the socket 41 and the mounting seat 40 are detachably connected.

[0031] In this embodiment, a slot 410 and a pin hole 411 are provided on the socket 41, and a positioning groove 400 and a locking hole 401 corresponding to the slot 410 and the pin hole 411 respectively are provided on the mounting base 40; corresponding threaded holes are also provided on the socket 41 and the mounting base 40 respectively.

[0032] With the above design, when installing the inner container body 1, the user only needs to first securely install the mounting base 40 in the oven, then align the slot 410 with the positioning groove 400, and insert the latch after the locking hole 401 is aligned with the latch hole 411 to secure the socket 41. Furthermore, a nut can be used in conjunction with the threaded hole for further securement. To disassemble the inner container body 1, simply remove the nut and then remove the latch.

[0033] In this embodiment, an auxiliary block 25 is provided in the heat insulation portion 11 , and the auxiliary block 25 is fitted with the locking ring 24 .

[0034] In this embodiment, a support frame 26 is provided in the insulation part 11, an upper limit groove 29 and a lower limit groove 28 are provided on the support frame 26, a handle 27 is provided on the slide rod 20, the handle 27 can be stuck in the upper limit groove 29 or the lower limit groove 28, and the side baffle 12 is provided with an opening 120 at the corresponding upper limit groove 29 and the lower limit groove 28.

[0035] The circulating hot air is often mixed with dust and other impurities. After years of operation, a large amount of dust will accumulate inside the inner tank body 1. Since the size of the air outlet 14 is limited and the range that can be cleaned at the position of the air inlet 15 is also limited, it is difficult to thoroughly clean the inside of the inner tank body 1.

[0036] With the above-mentioned design, when it is necessary to clean the inside of the liner body 1, the user can lift the handle 27 through the opening 120, and the handle 27 can drive the slide bar 20 to slide upward until the upper limit groove 29, and then rotate the slide bar 20 to make the handle 27 stuck in the upper limit groove 29; the locking block 21 can move upward together with the slide bar 20 under the drive of the stop block 23, so that the lock buckle 210 leaves the lock hole 240. After losing the restriction of the lock buckle 210, the locking ring 24 can directly remove the sub-guide plate 3, which is convenient for the user to directly clean the sub-guide plate 3. At the same time, after the sub-guide plate 3 is removed, the effective area of the opening 120 at the air outlet 14 is increased, which is convenient for cleaning the liner body 1 and other components.

[0037] When the guide plate 3 needs to be installed, the user only needs to align the locking ring 24 on the guide plate 3 with the auxiliary block 25 and insert it. The auxiliary block 25 can assist the locking ring 24 in positioning and provide support for the locking ring 24. As the locking ring 24 is slowly inserted, the locking block 21 can be lifted up by the locking ring 24. When the lock buckle 210 is aligned with the lock hole 240, the locking block 21 that has lost its restriction automatically pops out under the action of the reset elastic member 22, so that the lock buckle 210 hooks the lock hole 240. Under the restriction of the lock buckle 210, the guide plate 3 can be firmly locked on the inner tank body 1.

[0038] In this embodiment, the reset elastic member 22 is preferably a high-temperature resistant spring to ensure that the locking block can still be pressed against the stopper 23 in a high-temperature environment. Since the heated hot air is at a high temperature, the heat insulation plate 13 can effectively isolate the high temperature of the air chamber 10 and protect the locking assembly 2.

[0039] In this embodiment, multiple groups of fixed air guide plates 7 and movable air guide plates 6 are provided in the air chamber 10. The fixed air guide plates 7 are installed in the air chamber 10, and the movable air guide plates 6 are fixedly installed on the branch guide plates 3. The fixed air guide plates 7 and the movable air guide plates 6 are both arc-shaped, and the chord length of the movable air guide plates 6 increases with the increase of the distance between the branch guide plates 3 and the air inlet 15.

[0040] Through the above design, both the fixed air guide plate 7 and the movable air guide plate 6 can guide the hot air in the air chamber 10, so that the airflow output from each set of air outlets 14 is consistent, ensuring that the interior of the oven can be evenly heated. The hot air entering from the air inlet 15 is smoothly guided into the air chamber 10 under the guidance of the first fixed air guide plate 7. Under the guidance of the movable air guide plate 6, part of the hot air will be directed to the air outlet 14 corresponding to the movable guide plate. The remaining hot air continues to move forward and is then blown out from the next set of air outlets 14 under the guidance of the next set of movable air guide plates 6, until the last gust of hot air is blown out from the last air outlet 14 under the guidance of the terminal fixed air guide plate 7. The curved fixed air guide plate 7 and movable air guide plate 6 can make the hot air turn more smoothly and increase the wind speed at the air outlet 14.

[0041] In this embodiment, a plurality of exhaust pipes 30 are provided on the guide plate 3 , and the exhaust pipes 30 pass through the air chamber 10 and the inner tank body 1 ; an air nozzle 5 is installed at the air outlet 14 .

[0042] Through the above design scheme, when hot air circulation is carried out, the air flow in the oven will be sucked into the exhaust pipe 30, and under the guidance of the fan, the air flow will be heated by the heating device and flow to the air inlet 15, and then be blown out from the air outlet 14 after being guided by the air chamber 10; the air nozzle 5 can effectively increase the flow rate of the hot air blown out of the air outlet 14, so that the temperature inside the oven can be quickly raised.

[0043] In this embodiment, the slide bar 20 is composed of multiple sections of single rods 200 of varying lengths. The arrangement of the single rods 200 facilitates installation as needed. In this embodiment, a threaded hole is provided at the front end of the single rod 200, and a threaded section is provided at the end of the single rod 200. This threaded section mates with the threaded hole, ensuring that the single rods 200 of the previous set can be securely mounted on the single rods 200 of the next set. A stopper 23 is located near one end of the threaded hole. A reset spring 22 on the single rods 200 of the previous set can force the locking block to abut against the stopper 23 of the single rods 200 of the next set. In this embodiment, through holes are provided in both the threaded hole and the threaded section. After tightening to a certain degree, the threaded hole and the through hole of the threaded section are aligned. In actual use, simply inserting a steel bar or the like into the through hole effectively prevents loosening during use.

[0044] Compared with the prior art, the utility model provides an oven liner. Under the drive of the fan, external air is drawn in from the exhaust pipe 30, and after being heated, it enters the air chamber 10 through the air inlet 15. The hot air in the air chamber 10 is blown out from the multiple air outlets 14 under the guidance of the fixed air guide plate 7 and the movable air guide plate 6. When cleaning is required, the user can lift the slide bar 20 through the handle 27. The slide bar 20 can drive the locking block 21 to rise and disengage the locking ring 24 from the locked state, making it convenient for the user to remove the sub-guide plate 3 for cleaning.

[0045] In the absence of conflict, the above embodiments and features therein may be combined with each other.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the scope of protection of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
