Description
Technical Field
The invention relates to the field of cookers, in particular to an exhaust cover plate structure for an integrated cooker and the integrated cooker with the exhaust cover plate structure.
Background
The integrated kitchen is a device integrating kitchen ranges and devices such as a steam box or an oven or a dish washer or a disinfection cabinet, the integrated kitchen ranges are generally arranged above cooking devices such as the steam box or the oven when being arranged, in order to solve the exhaust problem of the cooking devices such as the steam box or the oven, the exhaust ports of the cooking devices are generally arranged behind the panel of the kitchen ranges, and therefore when the integrated kitchen ranges work, the exhaust gas outside the cooking devices and the kitchen ranges is intensively absorbed through the range hood above the integrated kitchen ranges. For example, the integrated cooker structure disclosed in chinese utility model patent No. ZL201921126717.5 (publication No. CN 211372508U).
Above-mentioned exhaust mode has solved the exhaust problem of cooking equipment among the integrated kitchen, can guarantee exhaust efficiency through range hood's suction effect simultaneously, because the gas vent is seted up in the rear side of cooking utensils panel, consequently also can not bring the influence to user's cooking utensils. However, the following problems still exist with this type of venting: (1) in the using process of the integrated cooker, food residues and other dirt can easily enter the cooker liner through the exhaust port, and cleaning dead corners are easily formed; (2) greasy dirt is attached to the panel surface easily in the use of integrated kitchen to be difficult to the clearance, especially cooking equipment such as steam ager, oven are higher in the grease content in the exhaust gas when cooking food such as meat, are difficult to the clearance more.
Disclosure of Invention
The first technical problem to be solved by the present invention is to provide an exhaust cover plate structure for an integrated stove, which can prevent dirt from entering an exhaust port.
The second technical problem to be solved by the present invention is to provide an exhaust cover plate structure for an integrated stove, which has smooth exhaust and self-adaptive variation of the actual size of the exhaust port with the exhaust volume, in view of the prior art.
The third technical problem to be solved by the present invention is to provide an exhaust cover plate structure for an integrated stove, which is beneficial to cleaning the surface of the stove panel, aiming at the prior art.
The fourth technical problem to be solved by the present invention is to provide an integrated oven with the exhaust cover plate structure in view of the prior art.
The technical scheme adopted by the invention for solving at least one technical problem is as follows: the utility model provides an exhaust cover plate structure for integrated kitchen, its characterized in that, including being arranged in installing the exhaust base on the gas vent of cooking utensils panel and installing the exhaust cover plate in the installing port of exhaust base, the exhaust hole has been seted up on this exhaust cover plate, movable mounting has the sealing strip of the heat sensitivity that can deform by heating in this exhaust hole, above-mentioned exhaust cover plate has first face and the second face relative with this first face, correspondingly, above-mentioned sealing strip has first surface and the second surface relative with this first surface, and above-mentioned exhaust cover plate has two kinds of states at least:
in the first state, the first surface of the exhaust cover plate faces upwards and is installed in the installation opening of the exhaust base, the first surface of the sealing strip faces upwards, the second surface of the sealing strip is not subjected to the action of hot air pressure, and the sealing strip seals the exhaust hole;
in the second state, the first plate surface of the exhaust cover plate faces upwards and is installed in the installation opening of the exhaust base, the first surface of the sealing strip faces upwards, the second surface of the sealing strip is acted by hot air pressure, the sealing strip is deformed and partially separated from the hole edge of the exhaust hole, an exhaust gap for air to escape is formed between the edge of the sealing strip and the corresponding hole edge of the exhaust hole, and the size of the exhaust gap is changed along with the change of the hot air pressure received by the second surface of the sealing strip.
Further, the second face of exhaust cover plate is the plane, and this exhaust cover plate still has the third state, and under this third state, the second face of above-mentioned exhaust cover plate is installed in above-mentioned exhaust base's installing port up, and the second surface of above-mentioned sealing strip is up, and the first surface of sealing strip is heated the atmospheric pressure effect and is made this sealing strip spacing in the exhaust hole, and the second surface of this sealing strip flushes with exhaust cover plate's second face, and forms the clearance of giving vent to anger of gas effusion between the front side of exhaust cover plate and the front side mouth edge of installing port. Therefore, when the cooking equipment below the cooker is a steam box or the cooking equipment with the steaming function under the steaming function, the hot steam discharged outside the cooking equipment is blown to the upper surface of the cooker panel through the air outlet gap, and the wet and hot steam is easy to soften and clean oil stains on the surface of the panel, so that a user can clean the cooker panel conveniently.
Furthermore, the shape of the exhaust hole of the exhaust cover plate is in a long strip shape, the shape of the sealing strip is matched with the exhaust hole and embedded in the exhaust hole, the hole walls at the two ends of the exhaust hole are respectively provided with an insertion hole, the two ends of the sealing strip are respectively provided with an insertion strip which can be inserted into the corresponding insertion hole, and in the deformation process of the sealing strip, each insertion strip can be always inserted into the corresponding insertion hole. On the one hand, the sealing strip and the exhaust hole are convenient to movably install, on the other hand, the sealing strip can be prevented from being separated from the exhaust hole in the heating deformation process, and meanwhile, the exhaust hole is sealed again when the sealing strip is cooled and reduced.
Further, the lateral margins of the two sides of the first surface of the sealing strip extend outwards horizontally along the length direction of the sealing strip to form limiting convex edges, each limiting convex edge of the sealing strip is respectively abutted against the corresponding hole edge of the exhaust hole on the first plate surface of the exhaust cover plate from top to bottom in the first state, and each limiting convex edge of the sealing strip is abutted against the corresponding hole edge of the exhaust hole on the first plate surface of the exhaust cover plate from bottom to top in the third state. Therefore, the exhaust holes can be better sealed by the sealing strips when only the cooker is used, and when the surface of the panel is cleaned by steam generated by cooking equipment, the sealing strips can be limited by the upward steam pressure and the matching action of the limiting convex edges and the hole edges of the exhaust holes, so that the sealing strips are prevented from being deformed by heating.
Further, the exhaust hole vertically extends in the direction of the hole edges on the two sides of the first plate surface of the exhaust cover plate along the length direction to form exhaust blocking ribs. Therefore, even if the sealing strip deforms to form the exhaust gap, dirt can be prevented from entering the interior of the cooker through the exhaust hole by the exhaust blocking rib.
Furthermore, the shape of the mounting opening is square, correspondingly, the exhaust cover plate is also square, hasp edges are formed on the front opening edge and the rear opening edge of the mounting opening respectively along the length direction, the front end and the rear end of the exhaust cover plate can be respectively buckled on the corresponding hasp edges, and therefore the exhaust cover plate and the exhaust base can be stably mounted.
