Description

an insulating body

technical field

The utility model relates to a door body structure for an oven, in particular to an insulating door body designed to meet new temperature safety standards.

technical background

At present, due to the need to observe the cooking conditions of the food in the oven, an observation window is usually provided on the door of the oven. The observation window is generally made of single-layer glass, and the glass surface is not covered with thermal insulation materials, so that a large amount of heat in the oven goes outward. Radiation and dissipation cause energy loss, and the surface temperature of the glass is very high, which can easily cause accidental burns. In addition, Chinese patent ZL200520065044.9 discloses a door applied to an insulating door structure or a microwave oven, which includes a door frame and a coated glass door mounted on the door frame. The inner side is provided with a coated surface that reflects heat rays back into the oven or microwave cavity. After adopting the above structure, the problem of heat radiation and loss at the observation window of the oven is solved, and energy is saved. However, the cost of coated glass is high, and the temperature in the inner cavity of the oven is high. When working for a long time, the temperature of the glass surface is still high. In particular, the new European safety standards require that the temperature of the oven door and the outer surface of the glass be below 120°C. Therefore, a low-cost insulating door that can meet the new safety requirements is required.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and specific implementation methods, but this embodiment is not intended to limit the utility model, and all similar structures and similar changes of the utility model should be included in the utility model scope of protection.

As shown in Figure 6, the insulating body of this embodiment includes a door frame 1, a first glass plate 2, a left bead 3a for fixing the first glass plate 2, a right bead 3b, a lower bead 3c, an upper bead 3d, a second glass The plate 4, the lower door clip 5 supporting the second glass plate 4, the two door handle seats 6, and the two door handle seats 6 are connected with a door handle 7. The inner periphery of the door frame 1 is provided with a folded frame 1a, the first glass plate 2 is placed in the folded frame 1a, and the symmetrically arranged left and right beading bars 3a, 3b, upper and lower beading bars 3d, 3c are fixed on the door frame by fasteners 1, part of the bead 3a, 3b, 3c, 3d is pressed against the surface of the first glass plate 2, thereby fixing the first glass plate 2 in the door frame 1.

As shown in accompanying drawings 1 to 6, a second glass plate 4 consistent with the size of the door frame 1 is provided on the front end of the door frame 1, and a lower door clamp 5 is provided at the bottom of the door frame 1, and the bottom 5b of the lower door clamp 5 is fixed. On the bottom surface of the door frame 1, the front end of the lower door clamp 5 is provided with an upwardly bent baffle plate 5a, which is basically parallel to the front end surface of the door frame 1, and the distance between them is equivalent to the thickness of the second glass plate 4. The plate 4 is inserted in the space between the front end face of the door frame 1 and this shutter 5a. Door handle seats 6 are arranged on both sides of the upper end of the second glass plate 4 respectively, and a door handle 7 is connected between the two door handle seats 6 .
