Description

Technical Field

[0001] The invention relates to the field of ovens, and in particular to a magnetic double-door structure. Background Art

[0002] Electric ovens are mainly used for baking food. Some foods need to be opened in the middle of the baking process to apply sauce to increase the flavor and keep the food moist. For example, when baking chicken wings / chicken legs, sauce (such as honey, barbecue sauce or special sauce) is usually applied every 10-15 minutes during the baking process to make the skin more flavorful and golden.

[0003] In order to facilitate users to open the electric oven, the existing electric ovens are provided with a handle on the door. The user pulls the handle and the door opens in a planar rotating manner. Generally, in order to ensure that the food can be evenly heated and achieve the best cooking effect, the food is placed in the middle position close to the baking cavity of the electric oven. Considering the opening method of the door of the above-mentioned electric oven, if you want to brush sauce on the food in the middle position of the baking cavity, you must rotate the door at a large angle so that the device for adding sauce can enter the baking cavity. This opening method will directly fully open the baking cavity of the electric oven and contact it with the outside world, which will cause the internal heat to be lost rapidly and the temperature to drop sharply. The loss of temperature will cause the oven to need to be reheated to the set temperature, thereby increasing energy consumption and cooking time. Summary of the invention

[0004] The purpose of the present application is to provide a magnetic double-door structure to solve the problem that the existing electric oven needs to rotate the door at a large angle when adding sauce, so that the device for adding sauce can enter the baking cavity. This opening method will directly open the baking cavity of the electric oven and contact it with the outside world, which will cause the internal heat to be lost quickly. The specific technical solution is as follows:

[0005] A magnetic double-door structure is applied to an oven, comprising an oven body, a baking cavity being arranged in the oven body, a double-door structure being arranged at the exit of the baking cavity, the double-door structure being rotatably coordinated with the baking cavity, the double-door structure comprising two symmetrically arranged door panels, the oven body being provided with a slide groove for installing the door panels, and being configured such that when the door panel slides along the slide groove and reaches a predetermined position, the slide groove releases the rotation restriction on the door panel.

[0006] The side of the door panel is connected to a pillar protruding outward, and the door panel is slidably connected to the outlet. The two door panels are installed with conductive coils on two end faces opposite to each other. A first contact is provided on the door panel, and the first contact is electrically connected to the conductive coil. A second contact is provided inside the outlet. The oven body has a built-in power supply, and the second contact is electrically connected to the power supply. The first contact is conductive to the second contact, and the two door panels are controlled to move closer to or farther away from each other by changing the current direction of the conductive coil.

[0007] As one of the improvements of the above technical solution, the top surface or the bottom surface of the baking cavity is provided with the slide groove, the slide groove is arranged close to the outlet, the slide groove is arranged along the length direction of the outlet, the pillar extends into the slide groove, and the pillar is slidably connected to the slide groove.

[0008] As one of the improvements of the above technical solution, a guide groove is provided along the bottom surface of the slide groove, the pillar is cylindrical and a disc is connected to the end of the pillar, and the disc is slidably connected in the guide groove.

[0009] As one of the improvements of the above technical solution, the side of the pillar is connected to a limiting block, the oven body is provided with an opening on the end face of the outlet, the opening is arranged close to the side of the outlet, and the opening is connected to the slide groove.

[0010] As one of the improvements of the above technical solution, the top surface or bottom surface of the baking chamber is vertically connected to a limiting plate, the door panel is arranged against the limiting plate, the first contact is arranged on the inner top end of the door panel, and the second contact is arranged on the limiting plate.

[0011] As one of the improvements of the above technical solution, the first contact and the second contact of the door panel abutting against the limiting plate are not disconnected.

[0012] As one of the improvements of the above technical solution, a handle is provided on the door panel.

[0013] As one of the improvements of the above technical solution, vertically arranged elastic buffer belts are bonded to both side surfaces of the baking cavity, and the elastic buffer belts are arranged close to the opening.

[0014] As one of the improvements of the above technical solution, it also includes a control panel, and the first contact, the second contact, and the power supply are electrically connected to the control panel respectively.

[0015] The beneficial effects of the present application are as follows: by adjusting the current direction and magnitude of the conductive coil, the magnetic polarity and the attractive or repulsive force of the conductive coil can be flexibly controlled, thereby realizing the opening and closing of the double door. By driving the two door panels to move slightly laterally to open, it is ensured that the temperature inside the oven body is not easily lost while also being able to feed in a device for replenishing sauce. The conductive coil is energized only when the door panel needs to move, and can be powered off at other times, without consuming energy.

DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In existing electric ovens, when adding sauce, the door needs to be rotated at a large angle so that the device for adding sauce can enter the baking cavity. This opening method will directly open the baking cavity of the electric oven and expose it to the outside world, which will cause the internal heat to lose quickly. Please refer to Figure 1-7 The present invention provides an embodiment to solve the above problem, specifically comprising an oven body 1, a baking chamber 11 is arranged in the oven body 1, a double-door structure 2 is arranged at the outlet of the baking chamber 11, the double-door structure 2 comprises two symmetrically arranged door panels 21, the side of the door panels 21 is connected with a pillar 211 protruding outward, the door panels 21 are slidably connected in the outlet, the two door panels 21 are both installed with conductive coils 22 on two end surfaces opposite to each other, a first contact 221 is arranged on the door panels 21, the first contact 221 is electrically connected to the conductive coil 22, a second contact 5 is arranged in the outlet, a power supply 6 is built in the oven body 1, the second contact 5 is electrically connected to the power supply 6, the first contact 221 is conductive with the second contact 5, and the two door panels 21 are controlled to be close to or away from each other by changing the current direction of the conductive coil 22. The specific principle is as follows:

[0029] The conductive coil 22 that is energized will form a magnetic field around it. At this time, the entire conductive coil 22 can be approximated as a bar magnet.

[0030] When the two door panels 21 need to be closed:

[0031] By controlling the current direction inside the two conductive coils 22, the two ends of one conductive coil 22 that is powered on and the other conductive coil 22 that is powered on form an N pole and an S pole respectively. Since there is an attraction between different magnetic poles (N pole and S pole), the two conductive coils 22 will attract each other and approach each other, thereby driving the two door panels 21 to approach each other and finally close.

[0032] When the two door panels 21 need to be opened:

[0033] By controlling the current direction inside the two conductive coils 22, the two ends of one conductive coil 22 and the other conductive coil 22 that are powered on form the same poles. Since the same magnetic poles repel each other, the two conductive coils 22 will repel each other and gradually move away from each other, thereby driving the two door panels 21 to gradually move away from each other and open the oven.

[0034] On the basis of the above technical solution, by setting a control panel 3, the first contact 221, the second contact 5, and the power supply 6 are electrically connected to the control panel 3 respectively, and the control panel 3 is set on the outer side of the oven body 1. Preferably, the control panel 3 has at least one switch for controlling whether to enable automatic opening of the two door panels 21. The control panel 3 is preset with an automatic door opening operation logic to cooperate with the switch, and its operation logic is as follows: the control panel 3 will preset a maximum power-on time T0 for energizing the conductive coil 22. When the oven body 1 runs for a predetermined heating time, the control panel 3 will control the power supply 6 to energize the two conductive coils 22 respectively. The power-on time of the two conductive coils 22 is T. As T increases, the control panel 3 will control the power supply 6 to output a larger current, that is, the power-on time T is positively correlated with the current, and T does not exceed T0;

[0035] Preferably, the last period of the power-on time T is defined as T1, and T1 is 1-3 seconds. Within T1, the control panel 3 will control the power supply 6 to gradually weaken the current output to the conductive coil 22. It can be understood that the door panel 21 will gradually approach the side of the opening 14 driven by the conductive coil 22. In order to reduce the force of the door panel 21 hitting the opening 14, it is necessary to gradually weaken the current when reaching time T1 to reduce the repulsive force.

[0036] In some embodiments, vertically arranged elastic buffer belts are bonded to both sides of the baking cavity 11, and the elastic buffer belts are arranged close to the opening 14. The above scheme can also reduce the wear caused by the impact between the door panel 21 and the oven body 1 to a certain extent.

[0037] By adjusting the current direction and size of the conductive coil 22, the magnetic polarity and attractive or repulsive force of the conductive coil 22 can be flexibly controlled to realize the opening and closing of the double door. Compared with the traditional mechanical or hydraulic system, two conductive coils 22 are used as the driving device: the complex mechanical parts (such as hinges, gears or hydraulic cylinders) are reduced, and only the conductive coil 22 needs to be installed. The structure is more compact and suitable for applications in limited spaces. The conductive coil 22 is only energized when the door needs to move, and can be powered off at other times, without consuming energy. Compared with the continuously running motor or hydraulic device, the energy consumption is lower.

[0038] Although the above embodiment can control the opening and closing of the door panel 21, the lateral sliding of the double door requires sufficient lateral space to be reserved for the movement of the door panel 21, which is a limitation for areas with limited space such as kitchens. Therefore, it is necessary to make further improvements to the door panel 21 and use rotation as the main means of opening the door panel 21.

[0039] Specifically, a slide groove 12 is provided on the top surface or the bottom surface of the baking cavity 11, and the slide groove 12 is arranged close to the outlet, and the slide groove 12 is arranged along the length direction of the outlet, and the support 211 extends into the slide groove 12, and the support 211 is slidably connected to the slide groove 12, and a guide groove 13 is provided along the bottom surface of the slide groove 12, and the support 211 is cylindrical and the end of the support 211 is connected to a disc 212, and the disc 212 is slidably connected in the guide groove 13, and the side of the support 211 is connected to a limited block 213, and the oven body 1 is provided with an opening 14 on the end surface of the outlet, and the opening 14 is arranged close to the side of the outlet, and the opening 14 is connected to the slide groove 12. The top or bottom surface of the baking chamber 11 is vertically connected to the limiting plate 4, the door panel 21 is arranged close to the limiting plate 4, the first contact 221 is arranged on the inner top of the door panel 21, and the second contact 5 is arranged on the limiting plate 4. Specifically, the radius of the disc 212 is greater than the end face radius of the cylinder, and the side cross-sectional view of the slide groove 12 and the guide groove 13 is in a T shape. The disc 212 is used to limit the position to ensure that the pillar 211 or the door panel 21 will not deviate during the positioning process. When the pillar 211 and the disc 212 slide to the inside of the opening 14, the opening 14 will unlock the door panel 21 so that the door panel 21 can rotate;

[0040] It can be understood that when the pillar 211 and the disc 212 slide to the inside of the opening 14, the slide groove 12 will no longer limit the limit block 213, and the opening 14 can accommodate the pillar 211 and the limit block 213 at the same time. Specifically, the length of the opening 14 is greater than the length of the limit block 213 plus the diameter length of the pillar 211. At this time, by rotating the door panel 21 or rotating the pillar 211, the limit block 213 will enter the opening 14 from the slide groove 12, so that the door panel 21 can rotate; this technical solution not only optimizes space utilization, but also improves the user experience, and is suitable for scenes such as kitchens where space is limited and high frequency of use.

[0041] It should be noted that the first contact 221 and the second contact 5 of the door panel 21 abutting against the limit plate 4 are not disconnected. Specifically, when the door panel 21 abuts against the limit plate 4 and slides to any position, the first contact 221 and the second contact 5 will not be disconnected, ensuring that the control panel 3 can control the power supply 6 to energize the conductive coil 22.

[0042] In some embodiments, in order to facilitate opening of the door panel 21 , a handle 23 is provided on the door panel 21 . Preferably, the handle 23 is close to the middle position of the oven body 1 .

[0043] An additional control button can be configured to energize the conductive coil 22 so that the two door panels 21 move away from each other and form an entrance between the two door panels 21. At this time, the sauce can be delivered into the baking cavity 11 through the entrance. At this time, the oven body 1 is still heated, or the oven body 1 is still in operation, and the door panel 21 has not yet slid to a rotatable position, thereby ensuring safety during the process of adding sauce.

Therefore, the features defined as "first" or "second" may explicitly or implicitly include one or more of the features.
