[0043] According to the microwave shielding cover of the microwave cooking utensil of the embodiment of the present application (hereinafter referred to as microwave shielding cover), please see Figures 1 to 3 , including outer cover 100, shielding cover body 200, movable cover body 300 and steam valve 400. Among them, the outer cover 100 is suitable for covering to the cooking body of the microwave cooking utensil (not shown in the figure), the outer cover 100 is formed with steam outlet 110; The shielding cover body 200 is fixed to the side of the outer cover 100 facing the cooking body, is suitable for surrounding with the shielding cover on the cooking body to form a shielding cavity, the shielding cover body 200 is provided with a first through hole 210, a shielding plate 500 of food grade material is sealingly arranged corresponding to the first through hole 210, the shielding plate 500 is provided with an exhaust hole 510, the exhaust hole 510 is in fluid communication with the steam outlet 110; The movable cover body 300 is installed in at least one of the outer cover 100 and the shielding cover body 200, is suitable for surrounding with the inner container of the cooking body to form a cooking cavity, the movable cover body 300 and the inner container are located in the shielding cavity, that is, the movable cover body 300 is located on the side of the shielding cover body 200 facing the cooking body, the movable cover body 300 is provided with a second through hole 310; The steam valve 400 is installed between the shielding cover body 200 and the movable cover body 300, is suitable for conducting or disconnecting the second through hole 310 and the exhaust hole 510.
[0044] According to the microwave shielding cover of the embodiment of the present application, the shielding cover body 200 is not directly arranged corresponding to the steam outlet 110, but a first through hole 210 is arranged on the shielding cover body 200, a shielding plate 500 of food grade material is sealingly arranged corresponding to the first through hole 210, and an exhaust hole 510 is arranged on the shielding plate 500, so that the steam exhaust process no longer contacts the shielding cover body 200, but contacts the shielding plate 500 of food grade material. Therefore, even if part of the steam condenses into water and then flows back into the cooking cavity, it does not affect the safety of food use.
[0045] It is worth mentioning that the outer cover 100 refers to the remaining cover part of the microwave shielding cover after removing the shielding cover body 200 and the movable cover body 300, which can include the plastic cover body of the microwave shielding cover, including the structure for mounting the detector 600 mentioned later and the structure for forming the mounting cavity 130 mentioned later, etc. In addition, the "food-grade material" refers to a material that can be directly contacted with food, and in the embodiments of the present application, the temperature of the contact with the food is also considered to ensure that the food hygiene can still be ensured when the food contacts the corresponding component, and problems such as hot melting or generation of harmful substances are avoided.
[0046] During the operation of the microwave cooking appliance, the steam generated in the cooking cavity enters the steam valve 400 through the second through hole 310, flows from the gas outlet of the steam valve 400 to the shielding plate 500, passes through the exhaust hole 510 to the steam outlet 110, and is finally discharged from the microwave cooking appliance through the steam outlet 110. Among them, part of the steam enters the steam valve 400 and may be pre-cooled to become condensed water in the subsequent flow process.
[0047] According to an embodiment of the present application, the shielding plate 500 can be integrally installed on the shielding cover body 200. Here, the integral installation refers to all cases where the shielding plate 500 and the shielding cover body 200 are assembled or disassembled as a whole during the assembly or disassembly of the microwave shielding cover. That is, corresponding to the assembly process of the microwave shielding cover, the shielding plate 500 and the shielding cover body 200 are connected together first, and then the shielding plate 500 and the shielding cover body 200 are installed together as a whole to the outer cover 100; corresponding to the disassembly process of the microwave shielding cover, the shielding plate 500 and the shielding cover body 200 are disassembled together as a whole from the outer cover 100. From the connection relationship, the connection relationship between the integrally installed shielding plate 500 and the shielding cover body 200 can be welding, bonding, clamping, riveting or threaded connection, etc., and the specific connection relationship is not limited.
[0048] Alternatively, the shielding plate 500 can be integrally formed with the shielding cover body 200. In this case, the shielding plate 500 has a food-grade coating to ensure that the shielding plate 500 meets the requirements of the aforementioned "food-grade material".
[0049] According to another embodiment of the present application, the shielding plate 500 is not integrally installed on the shielding cover body 200, but is integrally installed on the steam valve 400. Among them, the steam valve 400 can include a valve body 430 and a valve cover 420, at this time the shielding plate 500 can be fixed on the valve cover 420. Further, during the assembly or disassembly of the microwave shielding cover, the shielding plate 500 and the steam valve 400 are assembled or disassembled as a whole. Among them, the connection between the shielding plate 500 and the steam valve 400 is also not limited, and can adopt welding, bonding, clamping, riveting or threaded connection, etc.
[0050] It is worth mentioning that since the steam valve 400 is generally integrally installed with the movable cover 300, and when the shielding plate 500 is integrally installed with the evaporator, it is equivalent to that the shielding plate 500 and the movable cover 300 are integrally installed. In the process of disassembling the movable cover 300, the steam valve 400 and the shielding plate 500 are also disassembled. In this case, when the movable cover 300 is installed on the outer cover 100 or the shielding cover 200 in a detachable manner, the cleaning of the movable cover 300, the steam valve 400 and the shielding plate 500 can be facilitated.
[0051] When the shielding plate 500 is integrally installed on the steam valve 400, in order to prevent the shielding plate 500 from not being installed in place during disassembly and ensure the shielding performance of the shielding plate 500 to microwaves, the detector 600 can be installed on the outer cover 100 according to the embodiments of the present application, and the detector 600 is used to detect the position of the shielding plate 500 relative to the first through hole 210. When the detector 600 detects that the shielding plate 500 is sealingly arranged in the first through hole 210, the microwave cooking appliance can work normally at this time; when the detector 600 detects that the shielding plate 500 is not installed in place, the microwave cooking appliance can issue a prompt information to prompt the user that the shielding plate 500 is not installed in place at present, and there is a risk of microwave leakage. Wherein, the ideal positional relationship between the shielding plate 500 and the first through hole 210 is that the shielding plate 500 and the first through hole 210 are completely sealed, so that microwaves cannot leak between the shielding plate 500 and the first through hole 210. Due to assembly or production errors, there may be a small gap between the shielding plate 500 and the shielding cover 200. In addition, it is also not excluded that when the shielding plate 500 is integrally installed on the shielding cover 200, the detector 600 is arranged to detect whether the shielding plate 500 is installed in place at the factory.
[0052] According to the embodiments of the present application, the detector 600 can adopt the type of position sensor, and the position sensor can be directly used to detect the position of the shielding plate 500, or the position sensor can also be used to detect the position of the movable cover 300 to indirectly determine the position of the shielding plate 500. In combination with Figure 1 , the detector 600 is installed on the side wall of the outer cover 100 and sealingly penetrates the shielding cover 200, and the detector 600 determines the position of the shielding plate 500 relative to the first through hole 210 by detecting the position of the movable cover 300. It is worth mentioning that since the space of the side wall of the outer cover 100 is large, the detector 600 can be arranged corresponding to the side wall of the outer cover 100, which can ensure the installation space of the detector 600. Alternatively, the detector 600 can be arranged corresponding to the first through hole 210, so that the detector 600 directly detects the position of the shielding plate 500, and at this time, the structure of the top of the outer cover 100 needs to be adaptively adjusted to ensure the installation of the detector 600.
[0053] The position sensor herein can adopt a contact sensor, such as a pressure sensor or a piezoelectric sensor, etc. Of course, the position sensor herein can also adopt a non-contact sensor, for example, the position sensor can be a Hall sensor, a proximity switch, an ultrasonic sensor or a laser sensor, etc. In addition to the form of the position sensor, the detector 600 can also adopt a microwave sensor. When the shielding plate 500 is not installed in place, microwaves will leak from the position of the first through hole 210, and by arranging a microwave sensor corresponding to the first through hole 210, it can be judged whether the shielding plate 500 is installed in place.
[0054] When the shielding plate 500 is integrally installed on the steam valve 400, that is, when the shielding plate 500, the steam valve 400 and the movable cover 300 are integrally installed, in order to ensure that the movable cover 300 is installed in place at the same time, the shielding plate 500 is also sealingly matched with the first through hole 210 of the shielding cover 200, the shielding plate 500 is arranged in the recess 220 of the shielding cover 200, and the edge of the shielding plate 500 is at least partially attached to the bottom of the recess 220. Of course, in order to ensure the sealing effect between the shielding plate 500 and the shielding cover 200, the attachment area between the shielding plate 500 and the shielding cover 200 can be increased as much as possible, for example, a sealing groove is arranged on one of the shielding plate 500 and the shielding cover 200, and a sealing protrusion that sealingly matches the sealing groove is arranged on the other one of the shielding plate 500 and the shielding cover 200, and the number of the sealing groove and the sealing protrusion is not limited.
[0055] In order to prevent microwaves from leaking through the exhaust hole 510 of the shielding plate 500, the diameter of the exhaust hole 510 should not be too large, for example, when the diameter of the exhaust hole 510 is less than 12mm, microwaves cannot leak through the exhaust hole 510. Of course, in order to ensure that the steam is smoothly discharged through the exhaust hole 510, the diameter of the exhaust hole 510 should not be too small, for example, the diameter of the exhaust hole 510 can be greater than 3mm. In summary, the diameter of the exhaust hole 510 arranged on the shielding plate 500 according to the embodiment of the application can be between 3mm and 12mm. Of course, under the premise of discharging steam and shielding microwaves, it is not excluded that the exhaust hole 510 can have other sizes. And the above only exemplifies the case that the exhaust hole 510 is a circular hole, obviously, the cross-sectional shape of the exhaust hole 510 is not limited by the examples herein, it can also be triangular, square, hexagonal, etc. Moreover, the number of the exhaust hole 510 on the shielding plate 500 is not limited, which can be 1, 2, 3, etc.
[0056] According to the embodiment of the application, in combination with Figure 2The outer cover 100 is provided with a first sealing member 120 corresponding to the steam outlet 110, and the steam valve 400 is provided with a second sealing member 410 corresponding to the outlet. The first sealing member 120 and the second sealing member 410 are in sealing contact with the shielding plate 500, and a sealed passage is formed in the first sealing member 120 and the second sealing member 410, which is in communication with the steam valve 400, the exhaust hole 510, and the steam outlet 110. By providing the first sealing member 120 and the second sealing member 410, the leakage of steam and microwaves can be further prevented. The structure of the first sealing member 120 and the second sealing member 410 is not limited, as long as the first sealing member 120 is in sealing contact with the upper surface of the shielding plate 500, and the second sealing member 410 is in sealing contact with the lower surface of the shielding plate 500. Since the second sealing member 410 is in contact with the condensed water that may flow back to the food (contacting steam, and the condensed water is formed by pre-cooling the steam), the second sealing member 410 is preferably made of food-grade material. Since the second sealing member 410 needs to have a certain elasticity, the material of the second sealing member 410 can be edible silicone material, including but not limited to food mold silicone, baby product silicone, medical device silicone, and kitchen appliance silicone. Of course, the first sealing member 120 can also be made of the same material as the second sealing member 410.
[0057] According to an embodiment of the present application, the shielding plate 500 can be made of stainless steel material. Of course, the specific material of the shielding plate 500 is not limited, as long as it meets the food contact requirements. In addition, the steam valve 400 can also be made of food-grade material, for example, the steam valve 400 can be made of polypropylene (PP), which has the structural characteristics of heat resistance and not easy to deform, and can prevent hot melting or the generation of harmful substances at high temperatures.
[0058] According to an embodiment of the present application, the food hygiene level of the shielding cover 200 is lower than that of the shielding plate 500, that is, the shielding plate 500 has a higher food hygiene level requirement, and thus the cost of the material can be controlled on the basis of meeting the food hygiene and safety requirements. The higher the food hygiene level, the safer it is for contact with food materials.
[0059] According to an embodiment of the present application, in combination with Figure 1 The first through hole 210 on the movable cover 300 and the second through hole 310 on the shielding cover 200 are arranged in a staggered manner to prolong the path of the steam and squeeze the bubbles carried in the steam as much as possible.
[0060] In combination with Figure 1The outer cover 100 is further formed with a mounting cavity 130 for mounting a non-contact temperature sensor, which forms a detection field covering the surface of the food to detect the temperature of the food.
[0061] According to the embodiment of the present application, a microwave cooking appliance is also provided, which comprises a cooking body and the microwave shielding cover described above.
[0062] According to the microwave cooking appliance of the embodiment of the present application, since it comprises the microwave shielding cover described above, it has all the technical effects of the microwave shielding cover, which will not be described here again.
[0063] Finally, it should be noted that the above embodiments are only used to illustrate the present application, but not to limit the present application. Although the present application has been described in detail with reference to the embodiments, those skilled in the art should understand that various combinations, modifications or equivalent replacements of the technical solutions of the present application do not deviate from the spirit and scope of the present application, and should be covered in the scope of the claims of the present application.
