Description

Technical Field

[0001] This utility model relates to the technical field of kitchen appliance accessories, specifically to microwave ovens. Background Technology

[0002] Accurately monitoring humidity changes within the microwave oven cavity is crucial for precise humidity control during operation. Therefore, humidity sensors are typically installed to monitor humidity in real time. However, current humidity sensor installations usually involve directly mounting the sensor housing to the side wall of the microwave oven casing using screws or similar fasteners. This screw installation requires drilling holes in the side wall, which compromises the casing's integrity, reduces its sealing performance, and weakens its structural strength, ultimately affecting the microwave oven's overall performance and usability. Utility Model Content

[0003] In view of this, the present invention provides a microwave oven to solve the problem that when installing with screws, it is necessary to make holes in the shell, which inevitably damages the integrity of the shell, resulting in poor sealing performance of the shell, and thus affecting the overall performance and use effect of the microwave oven.

[0004] This utility model provides a microwave oven including a shell and a humidity detection device; the humidity detection device includes a mounting box and a humidity sensor disposed in the mounting box; the shell is provided with a folded edge, and the mounting box is detachably mounted and fixed on the folded edge by a first connector.

[0005] Beneficial effects: By setting a folded edge on the housing and connecting the mounting box to the folded edge, it avoids opening holes in the housing. While ensuring that the housing can maintain good sealing, it provides a supporting foundation for fixing the mounting box, ensuring a stable and reliable connection between the temperature detection device and the housing. This effectively prevents the mounting box from loosening or shifting due to vibration during use, ensuring the strength, reliability and stability of the overall structure. Furthermore, the structure is simple, easy to install, and highly practical.

[0006] In one optional embodiment, the housing is provided with a vent hole, the mounting box is provided with an air inlet and an air outlet, the air inlet corresponds to the vent hole, the air outlet is staggered from the vent hole, and the humidity sensor is staggered from the vent hole and located on the side closer to the air outlet.

[0007] Beneficial effects: Because the air vent and vent are staggered, and the humidity sensor is also staggered and located near the air vent, the moisture entering the mounting box through the vent flows through the humidity sensor towards the air vent, allowing the humidity sensor to detect the humidity level inside the cavity in a timely and accurate manner. This creates a reasonable and efficient moisture conduction path. Furthermore, by avoiding direct contact with the vent, the humidity sensor is protected from microwave interference, ensuring the accuracy of its measurement data. Timely and accurate measurement of humidity inside the microwave oven provides reliable data support for humidity control, ensuring real-time and precise regulation of the humidity environment during cooking and improving cooking results.

[0008] In one optional embodiment, the housing includes a first sidewall, and the vent is disposed on the first sidewall; the folded edge is formed by bending outward from the upper edge of the first sidewall, and the mounting box is connected and fixed to the folded edge by a first connector.

[0009] Beneficial effects: Since the vent is located on the first side wall and the folded edge is formed by bending outward from the upper edge of the first side wall, the connection between the mounting box and the folded edge can be realized at the same time as the air inlet of the mounting box corresponds to the vent.

[0010] In one optional embodiment, the mounting box is a box structure with an opening on one side, and the open end of the mounting box is fastened to the vent hole to form the air inlet.

[0011] Beneficial effect: By making one side of the mounting box open and fastening the open end to the vent hole to form an air inlet, the manufacturing cost of the mounting box is saved.

[0012] In one optional embodiment, the mounting box includes a second side wall, a top wall, and a bottom wall; the second side wall is disposed opposite to the air inlet; the top wall is disposed at the top of the second side wall and connected to the folded edge; the bottom wall is disposed at the bottom of the second side wall, and the air outlet is disposed on the bottom wall.

[0013] Beneficial effects: By setting the top wall, a fixed connection between the mounting box and the folded edge is achieved, and the air outlet is set on the bottom wall, avoiding obstruction of the air outlet by the folded edge and other structures, ensuring that moisture can be smoothly discharged from the air outlet.

[0014] In one optional embodiment, a first connecting hole is provided on the folded edge, and a second connecting hole is provided on the top wall of the mounting box. The first connector passes through the first connecting hole and connects to the second connecting hole.

[0015] Beneficial effects: Since the first connector passes through the first connecting hole and connects with the second connecting hole, it not only achieves a reliable connection between the mounting box and the folded edge, effectively preventing the two from becoming loose or separating during use, but also achieves precise positioning of the mounting box, ensuring that the mounting box can be installed accurately in the predetermined position.

[0016] In one optional embodiment, the mounting box further includes a third sidewall and a fourth sidewall; the third sidewall is disposed on one side of the second sidewall and connected between the top wall and the bottom wall; the air outlet is located on the side near the third sidewall; the humidity sensor is mounted on the third sidewall; the fourth sidewall is disposed on the other side of the second sidewall, opposite to the third sidewall, and connected between the top wall and the bottom wall; the vent is located on the side near the fourth sidewall.

[0017] Beneficial effect: By fixing the humidity sensor to the third side wall and setting the vent hole on the side close to the fourth side wall, the humidity sensor and the vent hole are staggered.

[0018] In one optional embodiment, the third sidewall is provided with an installation port; the humidity sensor includes a fixed end and a detection end; the fixed end is connected to the third sidewall; one end of the detection end is connected to the fixed end, and the other end passes through the installation port and is located inside the mounting box.

[0019] Beneficial effects: The installation port enables the humidity sensor to be positioned and installed, ensuring that it can be installed in the preset location; the connection between the fixed end and the third side wall ensures a stable connection between the humidity sensor and the mounting box; and since the detection end passes through the installation port and is located inside the mounting box, it ensures that the detection end can directly contact the moisture inside the mounting box, thereby enabling humidity measurement.

[0020] In one optional embodiment, the outer periphery of the fixed end is provided with a connecting lug, which is detachably mounted and fixed to the third side wall by a second connector.

[0021] Beneficial effects: Since the connecting lug can be detachably installed and fixed on the third side wall through the second connector, it is convenient to install and remove the humidity sensor on the mounting box.

[0022] In one optional embodiment, the connecting lug is provided with a third connecting hole, and the third sidewall is provided with a fourth connecting hole, and the second connector passes through the third connecting hole and connects with the fourth connecting hole.

[0023] Beneficial effects: Since the second connector passes through the third and fourth connecting holes and connects, the locking action of the second connector ensures that the connecting lug fits tightly and is firmly connected to the third side wall, guaranteeing a reliable fixed connection between the mounting box and the humidity sensor, and effectively preventing the two from loosening or separating during use.

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0032] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0033] According to an embodiment of the present invention, a microwave oven is provided, including a housing 1 and a humidity detection device 2; the humidity detection device 2 includes a mounting box 21 and a humidity sensor 22 disposed in the mounting box 21; the housing 1 is provided with a folded edge 3, and the mounting box 21 is detachably mounted and fixed on the folded edge 3 by a first connector 4.

[0034] By setting a folded edge 3 on the housing 1 and connecting the mounting box 21 to the folded edge 3, opening holes in the housing 1 is avoided. While ensuring that the housing 1 can maintain good sealing, a supporting foundation is provided for fixing the mounting box 21. This ensures that a stable and reliable connection is formed between the temperature detection device and the housing 1, effectively preventing the mounting box 21 from loosening or shifting due to vibration during use. This ensures the strength, reliability and stability of the overall structure. Furthermore, the structure is simple, easy to install, and highly practical.

[0035] In a specific embodiment, there are multiple vent holes 11, and the multiple vent holes 11 are distributed in an array; the diameter of the vent holes 11 is in the range of 1-3mm.

[0036] In specific implementations, the connection method between the folded edge 3 and the housing 1 is not limited, and the two can be connected by welding.

[0037] In one embodiment, the housing 1 is provided with a vent 11, the mounting box 21 is provided with an air inlet 211 and an air outlet 212, the air inlet 211 corresponds to the vent 11, the air outlet 212 is staggered from the vent 11, and the humidity sensor 22 is staggered from the vent 11 and located on the side close to the air outlet 212.

[0038] Because the air outlet 212 and the vent 11 are staggered, and the humidity sensor 22 is also staggered from the vent 11 and located on the side closer to the air outlet 212, the moisture entering the mounting box 21 through the vent 11 flows through the humidity sensor 22 along its path to the air outlet 212. This allows the humidity sensor 22 to detect the humidity inside the cavity in a timely and accurate manner, forming a reasonable and efficient moisture conduction path. Furthermore, by avoiding the position directly opposite the vent 11, the humidity sensor 22 is protected from microwave interference, ensuring the accuracy of its measurement data. Timely and accurate measurement of the humidity inside the microwave oven provides reliable data support for humidity control, ensuring real-time and precise control of the humidity environment during cooking and improving cooking results.

[0039] In one embodiment, the housing 1 includes a first sidewall 12, and the vent 11 is disposed on the first sidewall 12; the folded edge 3 is formed by bending outward from the upper edge of the first sidewall 12, and the mounting box 21 is connected and fixed to the folded edge 3 by a first connector 4.

[0040] Since the vent 11 is located on the first side wall 12 and the folded edge 3 is formed by bending outward from the upper edge of the first side wall 12, the connection between the mounting box 21 and the folded edge 3 can be realized at the same time as the air inlet 211 of the mounting box 21 corresponds to the vent 11.

[0041] In one embodiment, the mounting box 21 is a box structure with an opening on one side, and the open end of the mounting box 21 is fastened to the vent hole 11 to form the air inlet 211.

[0042] By setting one side of the mounting box 21 as an opening, and fastening the open end to the vent hole 11 to form an air inlet 211, the manufacturing cost of the mounting box 21 is saved.

[0043] In one embodiment, the mounting box 21 includes a second side wall 213, a top wall 214, and a bottom wall 215; the second side wall 213 is disposed opposite to the air inlet 211; the top wall 214 is disposed on the top of the second side wall 213 and connected to the folded edge 3; the bottom wall 215 is disposed on the bottom of the second side wall 213, and the air outlet 212 is disposed on the bottom wall 215.

[0044] By setting the top wall 214, a fixed connection between the mounting box 21 and the folded edge 3 is achieved, and the air outlet 212 is set on the bottom wall 215 to avoid the folded edge 3 and other structures from blocking the air outlet 212, thus ensuring that moisture is smoothly discharged from the air outlet 212.

[0045] In one embodiment, the folded edge 3 is provided with a first connecting hole 31, and the top wall 214 of the mounting box 21 is provided with a second connecting hole 2141. The first connector 4 passes through the first connecting hole 31 and connects with the second connecting hole 2141.

[0046] Since the first connector 4 passes through the first connecting hole 31 and connects to the second connecting hole 2141, it not only achieves a reliable connection between the mounting box 21 and the folded edge 3, effectively preventing the two from becoming loose or separating during use, but also achieves precise positioning of the mounting box 21, ensuring that the mounting box 21 can be accurately installed in the predetermined position.

[0047] In a specific implementation, multiple first connectors 4 are provided, and these multiple first connectors 4 are arranged sequentially along the length extension direction of the folded edge 3. By setting multiple first connectors 4 to form multiple stress support points, the stress borne by the mounting box 21 is evenly distributed to each support point, avoiding excessive stress concentration in local areas, improving the stability and durability of the overall structure, effectively extending the service life, and reducing the risk of failure due to structural loosening or damage. Specifically, each first connector 4 is provided with a first connecting hole 31 and a second connecting hole 2141.

[0048] In a specific embodiment, both the first connecting hole 31 and the second connecting hole 2141 are threaded holes; the first connecting member 4 is a screw.

[0049] In one embodiment, the mounting box 21 further includes a third sidewall 216 and a fourth sidewall 217; the third sidewall 216 is disposed on one side of the second sidewall 213 and connected between the top wall 214 and the bottom wall 215; the air outlet 212 is located on the side close to the third sidewall 216; the humidity sensor 22 is mounted on the third sidewall 216; the fourth sidewall 217 is disposed on the other side of the second sidewall 213, opposite to the third sidewall 216, and connected between the top wall 214 and the bottom wall 215; the vent 11 is located on the side close to the fourth sidewall 217.

[0050] By fixing the humidity sensor 22 to the third side wall 216 and setting the vent 11 on the side close to the fourth side wall 217, the humidity sensor 22 and the vent 11 are staggered.

[0051] In one embodiment, the third sidewall 216 is provided with an installation port 2161; the humidity sensor 22 includes a fixed end 221 and a detection end 222; the fixed end 221 is connected to the third sidewall 216; one end of the detection end 222 is connected to the fixed end 221, and the other end passes through the installation port 2161 and is located inside the installation box 21.

[0052] The installation port 2161 enables the humidity sensor 22 to be installed and positioned, ensuring that the humidity sensor 22 can be installed in the preset position. By connecting the fixed end 221 to the third side wall 216, a stable connection between the humidity sensor 22 and the mounting box 21 is achieved. Furthermore, since the detection end 222 passes through the installation port 2161 and is located inside the mounting box 21, it is ensured that the detection end 222 can directly contact the moisture inside the mounting box 21, thereby achieving humidity measurement.

[0053] In one embodiment, the outer periphery of the fixed end 221 is provided with a connecting lug 223, and the connecting lug 223 is detachably installed and fixed on the third side wall 216 by a second connector 5.

[0054] Since the connecting lug 223 is detachably mounted and fixed on the third side wall 216 via the second connector 5, it is convenient to install and remove the humidity sensor 22 on the mounting box 21.

[0055] In a specific embodiment, multiple connecting lugs 223 are sequentially arranged around the outer periphery of the fixed end 221, effectively avoiding problems such as loosening or misalignment caused by single-point connection or uneven force, and ensuring the stability of the connection between the humidity sensor 22 and the mounting box 21. Specifically, there is no limitation on the number of connecting lugs 223; two, three, or four sets of connecting lugs 223 can be provided. Preferably, multiple sets of connecting lugs 223 are evenly arranged around the outer periphery of the fixed end 221.

[0056] In one embodiment, the connecting lug 223 is provided with a third connecting hole, and the third sidewall 216 is provided with a fourth connecting hole 2162. The second connector 5 passes through the third connecting hole and connects with the fourth connecting hole 2162.

[0057] Since the second connector 5 passes through the third connecting hole and connects to the fourth connecting hole 2162, the locking action of the second connector 5 makes the connecting lug 223 fit tightly and firmly with the third side wall 216, ensuring a reliable fixed connection between the mounting box 21 and the humidity sensor 22, and effectively preventing the two from becoming loose or separated during use.

[0058] In a specific implementation, both the third connecting hole and the fourth connecting hole 2162 are threaded holes; the second connecting member 5 is a screw.
