Oven

Abstract

The present invention relates to an oven which comprises an oven body which is provided with a baking cavity body inside, a front frame arranged at the face of the over body, an oven door which can open and close the cavity body and a faceplate which is arranged over the oven door. The oven body is provided with a vent. A gap is arranged between the oven door and the faceplate. The oven door is provided with a cooling passage which is provided with an upper intake and a lower intake. The upside of the cavity body is provided with a cover plate. The cover plate and the external wall of the cavity body form an air course with an inlet and an outlet. The inside of the oven body is provided with a fan which ensures the airflow inside the air course flows from the inlet to the outlet. The oven of the present invention is characterized in that the front frame is provided with a through hole which is corresponding to the gap and the upper intake; the inlet of the air course is corresponding to the through hole, which ensures that the lower intake of the cooling passage and the gap become a first air inlet and a second air inlet respectively; the vent on the oven body becomes an air outlet. The present invention uses the double functions of the natural rising of hot air and the compulsory driving of a motor, so the refrigeration effect of the oven door is better, meanwhile, the gap is used as the second air inlet, which also ensures the using safeness.

Description

technical field [0001] The invention relates to an oven, in particular to an oven with a cooling system. Background technique [0002] During the use of the oven, due to its high internal temperature, long-term use will cause damage to the internal electrical components and affect the service life of the oven. Moreover, the user is easily burned when standing in front of the oven or opening the oven door. [0003] In order to prevent the occurrence of this class of accidents, a cooling structure must be provided in the oven. European Patent No.EP330727 discloses a food oven. In this invention, the door is designed to be composed of inner, middle and outer layers of flat glass. Air is introduced from the lower end of the gap between the flat glasses and discharged from the upper end of the gap, thereby passing through Natural convection realizes natural cooling of the oven door. However, the natural convection adopted by this cooling structure cannot provide sufficient cool...

AI Technical Summary

Problems solved by technology

Its disadvantages are: (1), in this invention, the hot air is discharged from the bottom of the door through the gap of the door, if the user stands in front of the oven, his lower body is easy to be scalded; (2), on the oven control panel The air inlet is set in the center, and the structure that the upper air duct and the door air duct are closely connected is difficult to realize in actual processing; (3), in natural convection, hot air is generally convected from bottom to top, and this The invention is to force the wind to flow in from the air inlet provided on the top of the control panel and the box, pass through the air duct and the gap between the inner and outer glass of the door, and then discharge from the bottom of the door, which requires a large force on the fan. The power to ensure forced convection increases the energy consumption of the whole oven; (4), the cooling system of the oven will form a high-temperature zone on the rear and both sides, when the oven is installed in the kitchen cabinet, it will cause the contact parts of the cabinet High temperature, there is a safety hazard

[0006] In addition, the most important thing is that in the three inventions disclosed above, only the cooling of the oven door is considered, and the cooling of other parts of the oven, such as the rear and side walls of the oven, are not considered.
