Abstract
Description
Technical Field
[0001] The utility model relates to the field of steam ovens, in particular to a door cooling and exhaust system for a steam oven. Background Art
[0002] A steam oven is a device that integrates the functions of a steamer and an oven. It is commonly used in home kitchens. It generally adopts a pull-down sliding door and is installed under the integrated stove. Steam is provided to the inner pot through an evaporation plate or an external evaporator to cook food.
[0003] In order to prevent scalding accidents caused by excessive door temperature, a multi-layer insulating glass is generally set on the front of the door. In the prior patent CN216984505U, a door cooling structure of the steam oven is further set. The fan is used to ventilate and cool from top to bottom through the heat dissipation interlayer of the door, and a return hole is set at the top to convert part of the overflowing steam into condensed water for recovery.
[0004] However, in the above structure, the high-temperature steam is eventually discharged from the sides and bottom of the door body. If there is a cabinet under the steam oven, the condensed water formed during the exhaust process can easily cause corrosion or mold. Therefore, the inventor conducted further research on this and developed a steam oven door cooling and exhaust system, which resulted in this case. Utility Model Content
[0005] The utility model aims to provide a steam oven door cooling and exhaust system, which can prevent the door from scalding the user and prevent condensed water from being directly discharged from the bottom of the door.
[0006] In order to achieve the above purpose, the technical solution of the utility model is as follows:
[0007] A steam oven door cooling and exhaust system comprises a cooling fan, a cooling air duct and a door body, wherein the cooling fan and the cooling air duct are located above an inner tank, an upper rib is provided on the top of the door body, a plurality of upper vents are formed on the upper rib, the upper vents are connected with the cooling air duct, a horizontal lower rib is provided on the bottom of the door body, a plurality of lower vents are formed on the lower rib, a sewage box is provided on the bottom of the lower rib, and a gap is left between the sewage box and the door body.
[0008] Through the above arrangement, the air flow of the cooling fan passes through the cooling air duct, the door body, and is finally discharged from the gap between the door body and the sewage box. Due to the obstruction of the sewage box, the steam discharged from the steam oven when in use will not be blown toward the cabinet or countertop under the steam oven door, but will be discharged into the gap between the sewage box and the door due to the obstruction of the sewage box, and the condensed water will directly drip into the sewage box.
[0009] Furthermore, a heat-insulating cavity is provided between the upper vent and the lower vent.
[0010] Furthermore, the upper vents and the lower vents are strip-shaped hole structures.
[0011] Furthermore, the upper rib is inclined, and the contact surface between the upper rib and the cooling air duct is also inclined.
[0012] Furthermore, the sewage box is in an elongated strip shape, and its length is consistent with the width of the door body.
[0013] After adopting the above scheme, the utility model has the following advantages compared with the prior art:
[0014] It can prevent high temperature steam and condensed water from corroding the countertop or cabinet under the steam oven, avoid mildew, and ensure a clean kitchen environment. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Description of symbols
[0018] Cooling fan 1, cooling air duct 2, door body 3, upper retaining edge 31, upper vent 311,
[0019] Lower rib 32, lower vent 321, heat insulation cavity 33,
[0020] Sewage box 4. DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] like Figure 1 As shown, a steam oven door cooling and exhaust system includes a cooling fan 1, a cooling air duct 2, a door body 3, and a sewage box 4, wherein the cooling fan 1 and the cooling air duct 2 are located above the inner pot, the door body 3 is arranged on the front of the inner pot, and the sewage box 4 is located below the door body 3. The sewage box 4 is an elongated structure as a whole, and its length is consistent with the width of the door body 3.
[0023] like Figure 2 As shown, an inclined upper rib 31 is provided on the top of the door body 3, and a plurality of upper vents 311 are opened on the upper rib 31, and the upper vents 311 are connected with the end of the cooling air duct 2, and a horizontal lower rib 32 is provided on the bottom of the door body 3, and a plurality of lower vents 321 are opened on the lower rib 32, and the lower vents 321 are relatively located above the sewage box 4, and the upper vents 311 and the lower vents 321 are both strip hole structures; and a gap is left between the sewage box 4 and the door body 3, and an insulating cavity 33 is provided between the upper vents 311 and the lower vents 321 for isolating the heat in the liner.
[0024] The airflow generated by the cooling fan 1 passes through the cooling air duct 2 and the door body 3, and is finally discharged from the gap between the door body 3 and the sewage box 4. Due to the obstruction of the sewage box 4, the steam discharged from the steam oven when in use will not be blown toward the cabinet or countertop under the steam oven door, but will be discharged into the gap between the sewage box 4 and the door due to the obstruction of the sewage box. The condensed water generated on the door body 3 will be guided into the sewage box 4.
