Description

Technical Field

[0001] The utility model belongs to the technical field of commercial ovens and relates to an oven cooling filter device and a commercial oven. Background Art

[0002] Commercial ovens are widely used in bakeries and other places. Compared with household ovens, commercial ovens have larger volumes, higher power, and higher requirements for frequency of use, durability, and stability. Among them, due to the larger volume of commercial ovens, a large amount of high-temperature hot air will be generated after the ingredients are baked and heated, and a large amount of high-temperature steam will be generated in the steaming and baking mode. When these high-temperature hot air and steam are discharged from the exhaust pipe, the exhaust pipe temperature is very high, and there is a safety hazard of scalding people. In addition, high-temperature hot air and steam will carry oil stains, food residues, etc. when they are discharged. If they are directly discharged into the outdoor atmosphere, it will cause air pollution and do not meet environmental protection requirements. Therefore, it is necessary to further improve and improve the existing commercial ovens. Utility Model Content

[0036] Example:

[0037] like Figures 1 to 6 As shown, the oven cooling filter device of this embodiment includes an oven box 1, an air intake pipeline 21, a first exhaust pipeline 22, a cooling filter bin 3, a filter element 4, a heat exchange unit 5, a fan 6 and a second exhaust pipeline 23.

[0038] The air inlet end of the oven box 1 is connected to the air inlet pipeline 21, and the air outlet end of the oven box 1 is connected to one end of the first exhaust pipeline 22. Normal temperature air is transported into the oven box 1 through the air inlet pipeline 21, and the high temperature hot air and steam of the oven box 1 are discharged from the first exhaust pipeline 22 into the first chamber 31 of the cooling filter bin 3.

[0039] The cooling filter chamber 3 is provided with a first chamber 31 and a second chamber 32. The first chamber 31 is connected to the second chamber 32 via an air duct 33. A filter 4 is provided inside and / or at the end of the air duct 33. When the airflow flows from the first chamber 31 to the second chamber 32 via the air duct 33, oil stains, food residues, etc. carried in the airflow are filtered by the filter 4. The filter 4 is provided as a filter fiber cotton.

[0040] An assembly rack 311 is disposed in the first chamber 31 , and the heat exchange unit 5 is assembled on the assembly rack 311 .

[0041] The heat exchange unit 5 is specifically configured as a water-cooled heat exchanger, the water inlet end of the water-cooled heat exchanger is connected to a water inlet pipeline 51, and the water outlet end of the water-cooled heat exchanger is connected to a water outlet pipeline 52. A solenoid valve 511 is provided on the water inlet pipeline 51, and the solenoid valve 511 is used to open and close the water inlet pipeline 51. After the solenoid valve 511 opens the water inlet pipeline 51, the cooling water flows through the water-cooled heat exchanger through the water inlet pipeline 51, exchanges heat with the high-temperature hot air and steam in the first chamber 31, and the heated cooling water flows out through the water outlet pipeline 52. Among them, the heated cooling water can provide warm water for users.

[0042] The other end of the first exhaust pipe 22 is connected to the first chamber 31. The other end of the first exhaust pipe 22 faces the water-cooled heat exchanger so that the high-temperature hot gas and steam directly impact the water-cooled heat exchanger to improve the heat exchange efficiency.

[0043] The air inlet end of the fan 6 is connected to the second chamber 32, and the air outlet end of the fan 6 is connected to the second exhaust pipeline 23. After the fan 6 is started, air flow is generated from the air inlet pipeline 21, through the oven box 1, the first exhaust pipeline 22, the first chamber 31, the air duct 33, the second chamber 32 to the second exhaust pipeline 23, so as to take out the high-temperature hot air and steam generated in the oven box 1.

[0044] In this embodiment, the body of the fan 6 is located inside the second chamber 32, so that the fan 6 does not occupy additional assembly space, making the overall structure of the device compact. In addition, because the oil stains, food residues, etc. carried by the wind are blocked in the first chamber 31, they will not contaminate the body of the fan 6 in the second chamber 32.

[0045] The first exhaust pipeline 22 is provided with a damper 221, which is used to open and close the first exhaust pipeline 22. After the damper 221 opens the first exhaust pipeline 22, the oven box 1 is connected to the first chamber 31.

[0046] The cooling filter compartment 3 is located inside the cover body 7, so that the cooling filter compartment 3 is wrapped by the cover body 7 to achieve safety protection.

[0047] The cover body 7 is assembled on the top of the oven box body 1, so that the cover body 7 and the oven box body 1 are integrated into one body, and the overall outer contour is compact, which does not occupy too much space in the user's use place.

[0048] A commercial oven is provided with the oven cooling filter device of this embodiment.

[0049] So far, the present embodiment has been described in detail in conjunction with the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the oven cooling filter device and commercial oven of the utility model. The oven cooling filter device of the utility model is applied to a commercial oven. When the fan 6 is started, the high-temperature hot air and steam generated in the oven box 1 enter the first chamber 31 of the cooling filter bin 3 from the first exhaust pipe 22. The heat exchange unit 5 absorbs the heat of the high-temperature hot air and steam, so that the temperature of the gas discharged from the second exhaust pipe 23 is lower; at the same time, the oil stains, food residues, etc. carried by the high-temperature hot air and steam are blocked by the filter element 4 in the first chamber 31, and the oil stains, food residues, etc. will not contaminate the second chamber 32 and the fan 6. The user only needs to regularly maintain and clean the filter element 4 and the first chamber 31, and the maintenance and cleaning work intensity is low.

[0050] Of course, the above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the utility model and should be protected by the utility model.
