Description

Technical Field

[0001] The invention relates to the technical field of ovens, and in particular to a split oven. Background Art

[0002] An oven is a sealed appliance used to bake food or dry products, and is divided into household appliances and industrial ovens. Household ovens can be used to process some pasta, and have a relatively small adjustable temperature range, and are only suitable for thawing food or heating and cooking appropriately. Ovens in the prior art are usually one-piece, mainly made of an insulating aluminum or steel wall to form an outer shell, enclosing an internal space forming a heat generation area and a cooking area, and the outer shell usually includes at least partially transparent walls and at least one door for opening the oven to facilitate taking food out of the cooking area. However, this one-piece oven has the following disadvantages:

[0003] 1. Although the overall shape of the oven is made into a rectangular shape for easy storage, for different volumes, especially for large-volume ovens, it occupies a large volume. When not in use, a lot of storage area for home appliances is wasted. The reason is that the internal space of the oven is too large and is not suitable for long-term storage of items. If there is really no storage space, people usually wait for the oven to cool down after use, and then use the internal space of the oven to store items. Then, when using the oven, it has to be taken out, which can easily cause the internal items to be frequently moved and damaged, or the items or the oven may fall over due to the hassle of taking them out;

[0004] Second, the oven cannot be disassembled. After heating food, the splashed grease or evaporated water will always form stains inside the oven. Therefore, when cleaning, you can only open the oven door on one side and reach into the space with a cleaning cloth to wipe. However, this method cannot achieve a good cleaning effect for corners or bumpy places, and the remaining stains are easy to mold and deteriorate, and even drip into the next heated food, causing pollution;

[0005] 3. The oven can only be used as a sealed device to process and cook food. After a long period of use, problems such as heat dissipation are likely to cause greater safety hazards. In addition, for some special foods and special cooking methods, the closed oven cannot observe the heating changes of the food well, especially the cooking method that requires adding different seasonings at the appropriate time during the heating process. The integrated oven cannot open the oven door to bake, but can only constantly turn off and on the oven heating switch. This is not only inconvenient to use, but also difficult to maintain the original temperature for continued heating, affecting the deliciousness of the food. Summary of the invention

[0006] In order to solve the problems existing in the above-mentioned prior art, the present invention aims to provide a split type oven. The present invention is a split structure design, which is divided into two detachable upper and lower parts. Through different combinations, the oven can be used normally when the cover is closed, and the upper shell can be turned over and inserted into the lower shell, which is convenient for storage, saves storage space, and is also convenient for cleaning.

[0007] A split type oven according to the present invention comprises:

[0008] A lower shell, wherein a grilling net is arranged inside the lower shell, a plurality of first heat dissipation holes are arranged on the rear side of the lower shell, and a retractable door is arranged on the front side of the lower shell;

[0009] An upper shell, both sides of which extend outward in a step-like shape, and the step-like shape enables the upper shell to cover the upper part of the lower shell or to be inserted into the lower shell for storage;

[0010] A heating mechanism, located in the lower shell or in the upper shell;

[0011] A lock buckle is located on both sides of the lower shell and the upper shell, and the lock buckle is used to fix the relative position between the lower shell and the upper shell.

[0012] In one of the embodiments, the lock includes grooves arranged on both sides of the upper shell, and raised portions are provided on both upper and lower sides of the groove. Hook bodies are hinged on both sides of the upper end of the lower shell, and the hook bodies are adapted to the raised portions.

[0013] In one of the embodiments, corresponding magnets are respectively disposed on the edges of the overlapping sides of the lower shell and the upper shell.

[0014] In one embodiment, a space for accommodating the door body is provided at the bottom of the lower shell, and guide rails are provided on both sides of the space. The bottom side of the door body is rotatably connected to a rotating shaft, and both ends of the rotating shaft can reciprocate back and forth along the guide rails.

[0015] In one of the embodiments, a hook-shaped handle is provided on the outer side of the upper end of the door body, and when the door body is stored in the space, the handle is buckled on the outer edge of the bottom of the lower shell body.

[0016] In one of the embodiments, four corners of the bottom of the lower shell are each provided with a truncated cone-shaped first support leg, and the height of the first support leg is greater than the height of the handle protruding from the bottom surface of the lower shell when the door body is stored.

[0017] In one of the embodiments, at least two layers of first protrusions are provided on both sides of the interior of the lower shell, and the grilling net is clamped between the multiple layers of the first protrusions.

[0018] In one of the embodiments, a plurality of second heat dissipation holes are provided on the rear side of the upper shell, and second protrusions are provided on the left and right sides of the upper shell, and the second protrusions are used to place the grill.

[0019] In one embodiment, second legs are disposed at four corners of the upper surface of the upper shell.

[0020] In one of the embodiments, a control button and a display are provided on the front side of the upper shell, and the control button and the display are respectively connected to the heating mechanism signal.

[0022] 1. The present invention is a split structure design, which is divided into two detachable upper and lower parts. Through different combinations, it can be used normally as an oven when covered. The upper shell can be turned over and inserted into the lower shell, which is convenient for storage, saves storage space, and is also convenient for cleaning.

[0023] 2. The locks on both sides of the device have the same structure. Therefore, no matter which assembly method is used, the hook body can cooperate with the protrusion in the groove to fix the lower shell and the upper shell, thereby realizing two different combination methods for normal use and storage. At the same time, the magnets are used for positioning to further prevent the upper and lower shells from shifting relative to each other.

[0024] 3. The door body can be turned outward by rotating along the bottom shaft, and then the shaft can be moved along the guide rail to store the door body in the bottom space of the lower shell to hide the door body, making it convenient for users to take and put food and grill, better saving the space occupied by the door body and facilitating cleaning inside the oven.

[0025] 4. The present invention can be used as a grill plate by turning the upper shell over. Since the heating mechanism is located in the upper shell, the device can be used as an oven and a grill plate to directly fry and grill food. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] The drawings are only used for illustrative purposes and should not be construed as limitations on this patent. In order to better illustrate this embodiment, some parts of the drawings may be omitted, enlarged, or reduced, and do not represent the size of the actual product. For those skilled in the art, it is understandable that some well-known structures and their descriptions in the drawings may be omitted.

[0034] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. It can be said that the internal connection of two components is connected. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. The technical solution of the present invention is further explained below in conjunction with the accompanying drawings and embodiments.

[0035] like Figure 1-Figure 6 As shown, a split type oven of the present invention comprises:

[0036] A lower shell 1, a grill 3 is arranged inside the lower shell 1, a plurality of first heat dissipation holes are arranged on the rear side of the lower shell 1, and a retractable door 4 is arranged on the front side of the lower shell 1;

[0037] An upper shell 2, both sides of which extend outwardly in a step shape, and the step shape enables the upper shell 2 to cover the upper part of the lower shell 1 or to be inserted into the lower shell 1 for storage;

[0038] A heating mechanism is located in the lower shell 1 or in the upper shell 2;

[0039] The lock buckle 5 is located on both sides of the lower shell 1 and the upper shell 2 , and is used to fix the relative position between the lower shell 1 and the upper shell 2 .

[0040] The present invention is a split structure design, which is divided into two detachable upper and lower parts. Through different combinations, it can be used normally as an oven when the cover is closed, and the upper shell 2 can be turned over and inserted into the lower shell 1, which is convenient for storage and saves storage space. It is also convenient for cleaning. In the prior art, the applicant has noticed that ovens are usually designed as an integrated structure. Although it is convenient to make and can be moved at will, it actually occupies a large space. When not in use, the heating space inside the oven has no practical use at all, which also leads to the problem that it is difficult to thoroughly clean the inside of the oven. Therefore, the split oven designed by the present invention is divided into an upper shell 2 and a lower shell 1. The lock buckles 5 on both sides can make the lower shell 1 and the upper shell 2 cooperate with each other. When in use, Figure 1 As shown, the wider side of the upper shell 2 faces downward, the edge of the upper shell 2 is opposite to the edge of the lower shell 1, and then fastened by the lock 5, so that a cavity is formed inside the upper shell 2 and the lower shell 1 as a space for heating food, and then the heating mechanism is started to generate heat to heat the inside. The heating mechanism generally adopts a heating tube connected to a power source and other methods. According to the design of a specific model, it can be set in the upper shell 2 or in the lower shell 1. With the installation of the grill 3, the food is placed on the grill 3 to be close to the heat source, and the heat can be dissipated through the first heat dissipation hole on the rear side of the lower shell 1 to prevent the internal overheating for a long time and cause corrosion to the box body; and when stored, as shown in FIG. Figure 4 As shown, it can be placed upright or upside down, mainly by turning the upper shell 2 upside down and inserting it into the lower shell 1. The two sides of the lower shell 1 form a package for the upper shell 2, and due to the stepped design of the upper shell 2, its heating structure and other parts can be embedded in the interior of the lower shell 1, thereby reducing the occupied space and facilitating washing and cleaning separately. They can also be locked together by the lock 5. After drying, the interior of the inverted upper shell 2 can be used to directly carry some small items.

[0041] In one embodiment, the lock 5 includes grooves 51 disposed on both sides of the upper shell 2, and protrusions are disposed on both upper and lower sides of the groove 51. Hooks 52 are hinged on both sides of the upper end of the lower shell 1, and the hooks 52 are adapted to the protrusions. Figure 1 and Figure 4As shown, the locks 5 on both sides of the device are of the same structure, so no matter what assembly method is used, the hook body 52 can cooperate with the protrusion in the groove 51, thereby fixing the lower shell 1 and the upper shell 2, and realizing two different combinations, so as to facilitate normal use and storage. Furthermore, in order to make the cooperation between the upper and lower shells more stable when the oven is in normal use, the edges of the side where the lower shell 1 and the upper shell 2 overlap are respectively provided with corresponding magnets or signal transmission interfaces. The magnets can be adsorbed to provide the function of mutual positioning for the lower shell 1 and the upper shell 2 when the lock 5 is not fastened, so as to facilitate the buckling and cooperation between the hook body 52 and the protrusion, and further avoid the displacement of the upper and lower shells, thereby avoiding the situation of air leakage such as the door body 4 cannot be closed tightly, so as to prevent heating failure. In addition, this position can be set as a mutually compatible signal transmission interface, such as the cooperation of a plug and a socket, so as to realize electrical connection, so that the heating mechanism, power supply, controller and other electrical equipment that may be set on different shells can be connected and powered on in this way to distinguish whether the oven can be started normally. Similarly, a magnet can be used to form an inductive switch structure, and magnetic induction and internal sensors can be used to form an inductive connection device, so that the lower shell 1 and the upper shell 2 can form an inductive connection of the signal through the induction of the magnet, and different magnetic force sizes or magnetic force ranges can be set for lower shells 1 of different specifications. Then, the power supply or data can be connected through the inductive switch here, so that the electrical equipment in the upper and lower parts can work together. By identifying the lower shells 1 with different designs, the control part in the upper shell 2 can provide different working signals. For example, if the inner cavity space of the lower shell 1 is larger, a larger heating output power is required to achieve the corresponding heating temperature and heating effect.

[0042] In one embodiment, the bottom of the lower shell 1 is provided with a space for accommodating the door body 4, and guide rails are provided on both sides of the space. The bottom side of the door body 4 is rotatably connected to a rotating shaft, and both ends of the rotating shaft can reciprocate forward and backward along the guide rails. Figure 3As shown, the door body 4 can be turned outward along the bottom shaft by rotating, and then the shaft is moved along the guide rail, so that the door body 4 can be stored in the bottom space of the lower shell 1 to hide the door body 4, which is convenient for users to take and put food and the grill 3, better saves the space occupied by the door body 4, and facilitates the cleaning of the inside of the oven. When the door body 4 is folded up, it can cover the front side of the lower shell 1 and the upper shell 2. The corresponding position of the upper shell 2 can be provided with a magnet or a card slot to cooperate with the door body 4, so that the upper side of the door body 4 is close to the upper shell 2. A micro switch can be set at the position where the door body 4 and the door frame contact, which is used to sense and control whether the oven is working normally. When it is not working normally, such as the door body 4 is not closed tightly, the power is automatically cut off to prevent dangerous accidents such as electric shock or scalding. The door body 4 can be made of transparent material, which is convenient for observing the food being heated inside. In addition, a hook-shaped handle 41 is provided on the outer side of the upper end of the door body 4. When the door body 4 is stored in the space, the handle 41 is buckled on the outer edge of the bottom of the lower shell 1. The handle 41 facilitates the movement of the door body 4. At the same time, after the door body 4 is stored in the bottom space of the lower shell 1, the handle 41 is clamped at the outer edge, so that the door body 4 is not easy to slide out at will. The door body 4 can also be lifted out by the handle 41 when closing the door.

[0043] Furthermore, the four corners of the bottom of the lower shell 1 are provided with a truncated cone-shaped first support leg 11, which is used to support the entire oven to prevent the shell from directly touching the tabletop, etc., and reduce the heat transfer to the tabletop. The height of the first support leg 11 is greater than the height of the handle 41 protruding from the bottom surface of the lower shell 1 when the door body 4 is stored, so that the handle 41 will not scratch the tabletop. At least two layers of first protrusions are provided on both sides of the interior of the lower shell 1, and the grill 3 is clamped between the multiple layers of first protrusions. The interior of the lower shell 1 can be designed in layers according to the actual height of the oven, and can be designed as follows: Figure 2 As shown in the height, there are only two layers of first protrusions to clamp the grill 3, and it can also be designed as Figure 6 The larger internal space shown is convenient for subsequent optimization and upgrading of the machine model to meet the needs of different users for the volume of the oven, and the functions are more complete. The larger oven cavity allows the first protrusion to be provided with more layers, and then the baking nets 3 can be inserted respectively. When baking food, they can be arranged at different layers for simultaneous baking, or the position of the baking net 3 can be changed as needed, and the food can be baked by being closer to or farther away from the heat source; in addition, relatively, the door body 4 needs to be increased in height accordingly to cover the front sides of the lower shell 1 and the upper shell 2.

[0044] In one embodiment, the rear side of the upper shell 2 is provided with a plurality of second heat dissipation holes, which cooperate with the first heat dissipation holes of the lower shell 1 to form a heat dissipation structure. Since the heat pipe heats the oven cavity formed in the upper shell 2, the heat dissipation holes are close to the rear side of the position, which can allow the interior to cool down quickly after heating. Cover plates can be set at both heat dissipation holes, and the cover plates can be opened or closed according to actual use. Second protrusions are also provided on the left and right sides of the upper shell 2, and the second protrusions are used to place the grill 3. Figure 5 As shown, the upper shell 2 can be turned over to be used as a baking plate. The upper surface corners of the upper shell 2 are also provided with second legs 21 for supporting the upper shell 2. Since the heating mechanism is located in the upper shell 2, the device can be used as an oven and a baking plate for directly frying and baking food. In addition, the front side of the upper shell 2 is provided with control buttons and a display, which are respectively connected to the heating mechanism signal. The upper shell 2 controls the heating mechanism on the control buttons on the front side, and displays the temperature or heating time, etc. on the display. The control buttons are distinguished by color, and the display can be set with gravity sensing, so that no matter how the upper shell 2 is turned over, its font is always facing the user, which is convenient for the user to use it as an oven or a baking plate.
