The present invention belongs to the field of food processing, and particularly to an oil barrel and an electric fryer having the same.
In existing fryers (or electric fryers), oil barrels are all single-layer structures, and the materials of the oil barrels include aluminum (including tensile aluminum and cast aluminum), stainless steel, and cold-rolled plates processed by oil injection. There are plastic shells, stainless steel shells, or shells in other materials outside the oil barrels, so that a thermal insulation protective layer is formed between an oil barrel and user while the product modeling purpose is achieved. However, when an electric fryer product is normally used, the oil temperature therein may be about 200° C., and the temperature of the outside surface of the oil barrel will also be about 200° C., that is, the outside surface of the oil barrel has a problem of a too high temperature. At this time, if user touches the electric fryer inadvertently, he/she may be burned seriously and a security incident is then caused.
A purpose of the present invention is to overcome the aforesaid problems in the prior art and provide an oil barrel, which aims at solving the problem that the temperature of the outside surface of the oil barrel is too high.
The present invention is implemented as follows:
An oil barrel which is suitable for an electric fryer, the oil barrel comprises an outer shell shaped as a barrel, an inner shell shaped as a barrel disposed in a barrel cavity of the outer shell and having a distance from the outer shell, and a shell connector configured to connect the outer shell with the inner shell and connected between a lip edge of the outer shell and a lip edge of the inner shell; the outer shell, the inner shell and the shell connector cooperatively define a thermal insulation chamber; the outer shell of the oil barrel is provided with a vacuuming interface structure, which is configured to cooperate with a vacuuming device to evacuate air from the thermal insulation chamber and make the thermal insulation chamber become a vacuum chamber.
Optionally, an outside surface of the outer shell facing away from the thermal insulation chamber is coated with an appearance pattern layer.
Optionally, the oil barrel comprises a pair of handles, and the two handles are respectively disposed on the two opposite outside surfaces of the outer shell.
Optionally, the vacuuming interface structure is disposed on a bottom of the outer shell.
Optionally, the oil barrel comprises a protective masking lid configured for covering the vacuuming interface structure.
Optionally, the outer shell, the inner shell, and the shell connector are provided integrally.
Optionally, the oil barrel comprises at least three support legs connected to a bottom of the outer shell, and bottoms of the support legs are all located in a same plane.
The present invention further provides an electric fryer, the electric fryer comprises an oil barrel, a heating component and an upper cover component covering the oil barrel, the oil barrel is an oil barrel described above, the heating component includes a heating tube disposed in the barrel of a cavity of the inner shell and a control box electrically connected with the heating tube and controlling heating of the heating tube.
Optionally, the control box is fixed on the outside surface of an outer shell.
Optionally, the electric fryer comprises a frying net component, the frying net component includes a frying net configured for containing food to be fried and disposed in the barrel cavity of the inner shell, a hand shank disposed outside the oil barrel, and a frying net connector configured for connecting the frying net with the hand shank; the heating tube is arranged between the frying net and a bottom of the barrel cavity of the inner shell.
Based on the structure of the present invention, after the outer shell, the inner shell, the shell connector and the vacuuming interface structure are assembled together, a vacuuming device is used to evacuate air from the thermal insulation chamber and thereby make the thermal insulation chamber become a vacuum chamber; wherein, vacuum means an ideal state in which no substance exists, and the vacuum chamber herein means a chamber in which very little material exists. On the basis of this, and according to thermal principles, it can be known that heat conduction needs to be performed via a substance having a certain thermal conductivity. The thermal insulation chamber becomes a vacuum chamber after being evacuated by the vacuuming device, that is, by the evacuation process for the thermal insulation chamber, the heat conduction from the inner shell to the outer shell can be greatly prevented, such that an excellent heat insulation effect is provided so as to avoid a too high temperature of the outside surface of the oil barrel. The outer shell could maintain a lower temperature even during a continuous use, the safety performance of oil barrel is greatly improved, so that users can avoid being burned when touching the oil barrel accidentally, the personal safety of consumers is greatly protected, and safe and enjoyable use experience is brought to consumers. While the thermal insulation chamber provides the heat insulation function, the thermal insulation chamber can also provide a heat preservation function for hot oil in the oil barrel, so that the automatic constant-temperature time interval of the fryer having the oil barrel is lengthened, the purposes of saving electricity and conserving energy are achieved, and the fryer is more power-saving and more environment-friendly than other fryers of the same capacity and the same power.
In addition, the outside surface of the outer shell of the oil barrel has a characteristic of a low temperature. Therefore, when the oil barrel is specifically used in the fryer, the outside surface of the outer shell can be used as a decorative shell, and other outer shells does not need to be added on the outside of the oil barrel, the material cost, the mould cost, and the corresponding assembly work of these decorative shells are saved, so that the total cost of the fryer is reduced.
In order to illustrate the technical solutions of the embodiments of the present invention more clearly, the drawings used in the embodiments are briefly described below. It will be readily apparent that the drawings described below are only some embodiments of the present invention. For one of ordinary skill in the art, other drawings may be obtained according to these drawings on the premise of paying no creative effort.
In order to make the objectives, technical solutions and advantages of the present disclosure be clearer, the present disclosure will be further described in detail hereinafter with reference to the accompanying drawings and embodiments. It should be understood that embodiments described here are only intended to interpret the present invention but not to limit the invention.
It should be noted that when an element is referred to as being “fixed” or “disposed” to another element, it could be directly located on the other element or indirectly located on the another element. When an element is referred to as being “connected” to another element, it may be directly connected to the other element or indirectly connected to another element.
It should also be noted that the position terms in the embodiments of the present invention, such as left, right, top, bottom, and so on, are only relative concepts or take the normal using state of a product as a reference, and should not be considered as any limitation.
An embodiment of the present invention provides an oil barrel which is suitable for an electric fryer. The oil barrel is used to contain oil and heat the oil for cooking food. As used herein, the term “barrel” refers to a container having a fully or at least partially open top and which has side wall(s) and a bottom for containing frying oil to be heated.
