[0046] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0047] The existing temperature sensor 200 is inserted into the installation hole 110 of the microwave oven and fixed by a pressing sheet 300; see Figure 1 ,in, Figure 1 The arrow in the figure indicates the flow direction of microwave leakage; there is a gap between the temperature sensor 200 and the inner wall of the mounting hole 110, and because the oven wall of the microwave oven is a bent structure, there is a gap between the pressing sheet 300 and the oven wall of the microwave oven. During the operation of the microwave oven, part of the microwave will overflow into the gap through the gap and overflow from the gap, resulting in the problem of microwave leakage.

[0048] In view of this, the microwave cooking appliance provided by the embodiment of the utility model includes a microwave cooking appliance body 100, a sensor 200, a pressing sheet 300 and a sealing member 400; the sensor 200 is fixedly connected to the pressing sheet 300, the side wall of the microwave cooking appliance body 100 is provided with a mounting hole 110, the sensor 200 is inserted into the mounting hole 110, and the pressing sheet 300 is connected to the side wall of the microwave cooking appliance body 100; the sensor 200 passes through the sealing member 400, the sealing member 400 is clamped between the pressing sheet 300 and the side wall of the microwave cooking appliance body 100 and covers the mounting hole 110, or the sealing member 400 is located in the mounting hole 110, and the outer peripheral wall is in contact with the inner wall of the mounting hole 110.

[0049] Specifically, the sensor 200 and the pressing sheet 300 are riveted, interference-fitted or integrally formed by injection molding, so as to reduce the gap between the sensor 200 and the pressing sheet 300, thereby preventing microwave leakage.

[0050] See also Figure 2 and Figure 3The sensor 200 is inserted into the mounting hole 110, so that the sensor 200 detects the situation inside the microwave cooking appliance body 100. For example, when the sensor 200 is set as a temperature sensor, the temperature sensor detects the temperature inside the microwave cooking appliance body 100. The sensor 200 is fixedly connected to the pressing sheet 300, and the pressing sheet 300 is connected to the side wall of the microwave cooking appliance body 100, so that the sensor 200 is fixed. The sealing member 400 covers the mounting hole 110 or fills the mounting hole 110, so as to shield the microwave of the microwave cooking appliance and avoid the problem of microwave leakage. Furthermore, the seal 400 has elasticity, so that the seal 400 can be compressed under external pressure and restore its original shape when the external pressure is removed; when the seal 400 is filled in the mounting hole 110, the seal 400 is compressed when the seal 400 is installed in the mounting hole 110, and the seal 400 restores its original shape after installation, and fits tightly with the outer wall of the sensor 200 and the inner wall of the mounting hole 110, so as to avoid microwaves from the gap between the seal 400 and the sensor 200 or the gap between the seal 400 and the mounting hole 110. 10; when the sealing member 400 is sandwiched between the pressing plate 300 and the side wall of the microwave cooking appliance body 100, the sealing member 400 is compressed when the sensor 200 passes through the sealing member 400. After the sensor 200 is installed, the sealing member 400 returns to its original shape and fits tightly with the outer wall of the sensor 200, and the two ends of the sealing member 400 are respectively in contact with the side wall of the microwave cooking appliance body 100 and the pressing plate 300, so as to prevent microwaves from overflowing from the gap between the sealing member 400 and the sensor 200.

[0051] The structure and shape of the sealing member 400 are described in detail below:

[0052] In the optional scheme of the embodiment of the utility model, please see Figures 5 to 8 The sealing member 400 is provided with a through hole 410 , the sensor 200 passes through the through hole 410 , and the inner wall of the through hole 410 is in contact with the outer wall of the sensor 200 .

[0053] Specifically, the through hole 410 is configured to be circular to match the shape of the outer wall of the sensor 200 .

[0054] The sealing member 400 is provided with a through hole 410 , so that the sensor 200 can pass through the sealing member 400 , thereby enabling the sealing member 400 to seal the outer wall of the sensor 200 .

[0055] In an optional solution of the embodiment of the utility model, the sealing element 400 includes at least one metal mesh 420 ; when a plurality of metal meshes 420 are provided, the plurality of metal meshes 420 are stacked along the axial direction of the sensor 200 .

[0056] Specifically, in this embodiment, see Figures 5 to 7The cross section of the metal mesh 420 is set to be annular. Of course, when the sealing member 400 is sandwiched between the pressing sheet 300 and the side wall of the microwave cooking appliance body 100, the metal mesh 420 is set to have a circular through hole 410 and a square outer wall structure, which should also be within the protection scope of the embodiment of the utility model. Furthermore, the metal mesh 420 is made of stainless steel, copper or iron.

[0057] The metal mesh 420 is provided in single or multiple configurations to achieve a shielding effect on microwaves; and because the metal mesh 420 has mesh holes, it can reduce the weight of the sealing member 400 and achieve the effect of heat dissipation.

[0058] In an optional solution of the embodiment of the present utility model, the mesh holes of two adjacent metal meshes 420 are arranged in a staggered manner.

[0059] Specifically, when a plurality of metal meshes 420 are provided, the overall thickness of the plurality of metal meshes 420 after being stacked in sequence should not be too large to avoid affecting the normal use of the microwave cooking appliance.

[0060] When a plurality of metal meshes 420 are provided, the mesh holes of two adjacent metal meshes 420 are arranged in a staggered manner, so that the overall aperture of the sealing member 400 becomes smaller, thereby enhancing the shielding effect.

[0061] In an optional solution of the embodiment of the present utility model, the diameter of the mesh of the metal mesh 420 is less than or equal to 1 mm.

[0062] Specifically, the diameter of the mesh of the metal mesh 420 is set to 0.2mm, 0.5mm or 1mm, etc. Furthermore, the diameter of the mesh on a single metal mesh 420 is set to different sizes, and all are less than or equal to 1mm. Furthermore, the mesh is set to be circular, diamond, square or polygonal, etc., which should all be within the protection scope of the embodiment of the utility model. Please refer to Figure 7 In this embodiment, the mesh is set to be a regular hexagon, and the diameter of the circumscribed circle of the regular hexagon is less than or equal to 1 mm.

[0063] The mesh diameter of the metal mesh 420 is less than or equal to 1 mm to ensure that the metal mesh 420 can play a shielding effect.

[0064] In an optional solution of the embodiment of the present utility model, the sealing element 400 includes a metal sheet 430 and at least one metal mesh 420 ; the metal mesh 420 is fixed to the metal sheet 430 .

[0065] Specifically, the metal mesh 420 is bonded to the metal sheet 430 ; or, the metal mesh 420 and the metal sheet 430 are welded, etc.

[0066] The metal mesh 420 is fixed to the metal sheet 430 , thereby improving the shielding effect of the sealing member 400 .

[0067] In an optional solution of the embodiment of the utility model, the sealing member 400 includes a metal sheet 430 and / or a metal wire; when the sealing member 400 includes a metal sheet 430 and a metal wire, the metal wire is fixed to the metal sheet 430 .

[0068] Specifically, see Figure 8 The sealing member 400 includes a metal sheet 430; or, the sealing member 400 includes a metal wire, and the metal wire is wound around the outer wall of the sensor 200; or, the sealing member 400 includes a metal sheet 430 and a metal wire, and the metal wire is fixed to the metal sheet 430, and the metal sheet 430 supports the metal wire.

[0069] A simple metal sheet 430 or a metal wire, or a combination of a metal wire and a metal sheet 430 , can achieve the shielding effect of the seal 400 .

[0070] In an optional solution of the embodiment of the utility model, when the seal 400 is filled in the installation hole 110, a protrusion is provided at one end close to the pressing sheet 300, and both ends of the protrusion are respectively in contact with the outer wall of the microwave cooking appliance body 100 and the pressing sheet 300.

[0071] Specifically, the outer peripheral wall of one end of the sealing member 400 extends outward to form a protrusion.

[0072] The outer peripheral wall of the sealing member 400 is in contact with the inner wall of the mounting hole 110 to prevent microwave leakage, and the protrusion is in contact with the outer wall of the microwave cooking utensil body 100 and the pressing sheet 300 to further prevent microwave leakage. Of course, the sealing member 400 is provided with protrusions at both ends, which should also be within the protection scope of the embodiment of the utility model.

[0073] In an optional solution of the embodiment of the utility model, a probe is installed at one end of the sensor 200 extending into the interior of the microwave cooking appliance body 100.

[0074] Specifically, in this embodiment, the probe includes NTC (Negative Temperature Coefficient), where NTC refers to a thermistor phenomenon and material having a negative temperature coefficient and whose resistance decreases exponentially with increasing temperature.

[0075] The probe realizes the temperature measurement function of the sensor 200; and the probe is installed inside the microwave cooking appliance body 100 to directly detect the temperature inside the microwave cooking appliance body 100, thereby improving the detection accuracy.

[0076] In an optional solution of the embodiment of the utility model, the middle position of the sensor 200 is connected to the pressing piece 300 .

[0077] Specifically, see Figure 3The middle position of the sensor 200 refers to a position where the distance from the probe is 1 / 3-2 / 3 of the overall length of the sensor 200. Preferably, the pressing sheet 300 is made of metal material, such as stainless steel.

[0078] The middle position of the sensor 200 is connected to the pressing sheet 300 to balance the two ends of the sensor 200 and prevent the sensor 200 from tilting.

[0079] In an optional solution of the embodiment of the present invention, the sensor 200 is installed on the upper side of the microwave cooking appliance body 100 .

[0080] Specifically, see Figure 2 The mounting hole 110 is provided on the upper side of the side wall of the microwave cooking appliance body 100 , so that the sensor 200 is located on the upper side of the microwave cooking appliance body 100 .

[0081] Because the density of hot air is smaller than that of cold air, when substances are mixed, the smaller density rises and the smaller density falls; therefore, the temperature of the upper side of the interior of the microwave cooking appliance body 100 will be higher than the temperature of the lower side. The sensor 200 is located on the upper side of the microwave cooking appliance body 100, and the probe of the sensor 200 is located on the upper side of the microwave cooking appliance body 100, which helps to detect the highest temperature inside the microwave cooking appliance body 100. Then, when the temperature inside the microwave cooking appliance is too high, the sensor 200 can detect it at the first time, and transmit the information to the control module, thereby issuing an alarm.

[0082] In an optional solution of the embodiment of the utility model, the pressing sheet 300 is detachably connected to the side wall of the microwave cooking appliance body 100 .

[0083] Specifically, in this embodiment, see Figure 4 The pressing sheet 300 is configured in a rectangular shape, and one side is plugged into the side wall of the microwave cooking utensil, and the other side is connected to the side wall of the microwave cooking utensil via a fastener. Furthermore, the fastener is configured as a screw or a bolt. Of course, the snap connection between the pressing sheet 300 and the side wall of the microwave cooking utensil body 100 should also be within the protection scope of the embodiment of the utility model.

[0084] The pressing sheet 300 is detachably connected to the side wall of the microwave cooking appliance, which facilitates the installation and removal of the sealing member 400 and the sensor 200, and further facilitates the maintenance and replacement of the sealing member 400 and the sensor 200.

[0085] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
