Description

Technical Field

[0001] The utility model relates to the technical field of microwave ovens, in particular to a vehicle-mounted microwave oven. Background Art

[0002] Microwave ovens are common household appliances that can heat food using microwaves. The entire process does not involve open flames or gas. They are safe, reliable, and can significantly improve drivers' quality of life, making them popular.

[0003] For example, Chinese patent application number CN201420407751.0 discloses a microwave oven comprising a microwave oven body. The microwave oven body is characterized by an air filter installed at the air inlet, allowing filtered air to enter the body. The rear panel is provided with an open press pack, a snap fastener, or screws for securing the air filter. This solution utilizes the filter to filter air, improving air quality and providing favorable conditions for food preparation. However, if used directly in a vehicle, the fumes generated during food heating can contaminate the cabin environment. To address this, a filter assembly is typically installed in the vehicle microwave oven. The filter assembly is detachably connected to the air scoop to absorb and treat the fumes from the heating chamber. Since the filter assembly needs to be removed periodically for cleaning, frequent removal and installation will continuously stress the air scoop. If the air scoop is not securely assembled, this can affect the assembly stability of the filter assembly, resulting in a poor user experience.

[0004] In view of this, the present utility model is proposed. Utility Model Content

[0005] The problem solved by the utility model is that the air guide cover in the existing vehicle-mounted microwave oven has poor assembly stability and poor user experience.

[0006] To address the aforementioned issues, the present invention provides a vehicle-mounted microwave oven comprising a filter assembly, an air scoop, and an inner container. The filter assembly is positioned vertically at the outlet of the air scoop, and is used to remove fumes generated by the heating of food in the inner container. The bottom and top of the air scoop are fixedly connected to the inner container, respectively. This arrangement effectively improves the connection strength of the air scoop, ensuring that the filter assembly remains stably connected to the air scoop during frequent assembly and disassembly, preventing fumes from escaping from the connection between the filter assembly and the air scoop, and providing a better user experience.

[0007] Preferably, the inner container comprises a U-shaped frame, the front side and top of the U-shaped frame are respectively provided with a front plate and a top plate, the bottom of the air guide cover is fixedly connected to the top plate, and the upper part of the air guide cover is fixedly connected to the front plate. This arrangement has a simple structure, stable and reliable assembly, and is easy to produce and process.

[0008] Preferably, the front plate is provided with a mounting hole near the top, with plug-in blocks provided on the left and right sides and / or the top of the mounting hole. The air duct cover is provided at the top rear side of the front plate and fixed within the mounting hole, for conveying air within the liner to the filter assembly. Restriction slots are provided at corresponding positions of the air duct cover and the plug-in block, and the free end of the plug-in block passes through the restriction slot and is then bent for positional assembly. This arrangement secures the air duct cover in a direction perpendicular to the filter assembly, ensuring a stable and reliable connection of the air duct cover during frequent removal of the filter assembly, and providing strong assembly stability.

[0009] Preferably, the vehicle-mounted microwave oven includes a door assembly, a rotatable door hook is provided on one side of the door assembly, a switch assembly is provided on the inner pot on the side close to the door hook, the switch assembly includes an electromagnet, and a limiting shaft is provided on the side close to the door hook of the electromagnet, and the limiting shaft is electrically connected to the control panel for selectively limiting the door hook.

[0010] By setting the door opening time to first control the extension and retraction of the limit shaft to remove the door hook limit, the micro switch and connecting rod then work together to activate the door hook and finally open the door assembly. This setting effectively prevents the door assembly from opening due to accidental touch, prevents microwave leakage, and improves user safety.

[0011] Preferably, the switch assembly includes a bracket disposed on one side of the inner container, the electromagnet is disposed between the bracket and the inner container, and the sidewall of the limit shaft is selectively engageable with the door hook. This arrangement is structurally simple, with the limit shaft engaging the door hook to achieve position limiting, while the limit shaft's telescopic movement is controlled by a membrane switch and a control panel.

[0012] Preferably, the switch assembly further comprises a connecting rod and a micro switch arranged on the bracket, the micro switch being provided with contacts, one end of the connecting rod being rotatably arranged on the bracket, a first touch portion and a second touch portion corresponding to the door hook and the contact being respectively provided on both sides of the connecting rod, the distances between the first touch portion and the second touch portion and the first end of the connecting rod being L1 and L2 respectively, wherein L1<L2, the contact can move synchronously with the door hook through the connecting rod and actuate the micro switch.

[0013] This setting can effectively reduce the movement stroke of the door hook during the process of opening the oven door and before the microwave oven is powered off, while satisfying the movement stroke of the contacts on the micro switch and enabling the micro switch to operate and control the power off of the microwave oven. This reduces the amount of microwave leakage when the oven door is opened, and further reduces the harm of microwave leakage to the human body.

[0014] Preferably, connecting pins are provided at both ends of the filter assembly, and elastic connecting sleeves are provided at both ends of the air guide cover. The connecting pins are preassembled with the filter assembly, and the elastic connecting sleeve is preassembled with the air guide cover, and the connecting pins are inserted into the elastic connecting sleeves. This arrangement enables the assembly of the filter assembly by inserting the connecting pins into the mounting holes and the interior of the elastic connecting sleeves, while simultaneously tightly connecting the two ends of the air guide cover to the filter assembly, thereby avoiding the problem of loose sealing between the two.

[0015] Preferably, the air guide cover includes a first inclined plate, first side edges are provided on both sides of the first inclined plate, connecting feet are provided at the bottom of the first side edges, and connecting holes are provided on the connecting feet for fixed connection with the top cover.

[0016] This arrangement can utilize the air guide cover to achieve assembly limitation of the elastic connecting sleeve, so that the elastic connecting sleeve is in a horizontal state after installation. At the same time, the elastic connecting sleeve can be used to assemble the filter assembly.

[0017] Preferably, the filter assembly includes a filter and an oil-absorbing layer. The filter is a porous structure with flanges formed around the filter, the flanges extending rearwardly.

DETAILED DESCRIPTION

[0029] In order to make the above-mentioned objects, features and advantages of the present invention more clearly understood, the following detailed description of the specific embodiments of the present invention is made in conjunction with the accompanying drawings. The technical features of the embodiments of the present invention can be combined without conflict.

[0030] Example 1

[0031] like Figure 1-7 As shown, a vehicle-mounted microwave oven includes a filter assembly 3, an air guide cover 5, and an inner pot 6. The bottom of the air guide cover 5 is fixedly connected to the inner pot 6. The filter assembly 3 is placed vertically and is located at the outlet end of the air guide cover 5, and is used to process the oil smoke generated by the heating of food in the inner pot 6; the air guide cover 5 is fixedly connected to the inner pot 6 on the side close to the filter assembly 3.

[0032] To ensure that the oil smoke in the inner tank 6 does not pollute the interior environment of the cab, the filter assembly 3 that filters the oil smoke needs to be frequently removed and installed. Because the filter assembly 3 is detachably mounted on the air scoop 5, frequent force must be applied to the air scoop 5 during removal and installation, making the connection stability of the air scoop 5 crucial. By fixing the bottom and top of the air scoop 5 to the inner tank 6, the connection strength of the air scoop 5 is effectively improved, ensuring that the filter assembly 3 remains connected to the air scoop 5 during frequent removal and installation, preventing smoke from escaping from the connection between the filter assembly 3 and the air scoop 5, and providing a better user experience.

[0033] As an example of the present invention, the inner liner 6 includes a U-shaped frame 64, with a front plate 63 and a top plate 62 provided on the front and top of the U-shaped frame 64, respectively. The bottom of the air guide hood 5 is fixedly connected to the top plate 62, and the top of the air guide hood 5 is fixedly connected to the front plate 63. This arrangement is simple in structure, stable and reliable in assembly, and easy to produce and process.

[0034] Preferably, a mounting hole 631 is provided near the top of the front plate 63, with plug-in blocks 633 provided on the left and right sides and / or the top of the mounting hole 631. The air scoop 5 is provided on the top rear side of the front plate 63 and within the mounting hole 631, for conveying air from the inner liner 6 to the filter assembly 3. Restriction slots 55 are provided at corresponding positions of the air scoop 5 and the plug-in blocks 633. The free end of the plug-in blocks 633 passes through the restriction slots 55 and is then bent for positional assembly. This arrangement secures the air scoop 5 in a direction perpendicular to the filter assembly 3. When the filter assembly 3 is frequently disassembled, the air scoop 5 remains stably and reliably connected, providing strong assembly stability.

[0035] Preferably, connecting pins 33 are provided at both ends of the filter assembly 3, and elastic connecting sleeves 51 are provided at both ends of the air guide cover 5. The elastic connecting sleeve 51 is a hollow structure. By inserting the connecting pin 33 into the front plate 63 and the elastic connecting sleeve 51, the filter assembly 3 can be quickly and detachably connected, which is convenient for quick disassembly and cleaning to remove oil droplets or other contaminants on the filter assembly 3, and prevent oil droplets from entering the cockpit and affecting the user experience; at the same time, the elastic connecting sleeve 51 makes the elastic part deform under the force caused by the insertion of the connecting pin 33 to tightly wrap the end of the connecting pin 33, thereby preventing the filter assembly 3 from loosening or falling off due to vibration of the microwave oven.

[0036] The connecting pin 33 comprises, from front to back, a handle portion 331, a second connecting portion 332, and a second fixing portion 333. These three components are integrally formed. The outer diameter of the handle portion 331 is larger than that of the second connecting portion 332, which in turn is larger than that of the second fixing portion 333. When the connecting pin 33 is inserted into place, the second connecting portion 332 resides within the fixing seat 35, leaving the handle portion 331 exposed. A first step forms at the junction of the handle portion 331 and the second connecting portion 332. This step engages the outside of the filter 32 of the filter assembly 3 and serves as a guide for determining whether the connecting pin 33 is properly inserted. The handle portion 331 facilitates handheld removal and installation of the filter assembly 3. The second fixing portion 333 is inserted into the elastic connecting sleeve 51, securing the connecting pin 33 to the elastic connecting sleeve 51.

[0037] Furthermore, a head 334 is provided at the rear end of the second fixing portion 333 , and the outer diameter of the head 334 is larger than that of the second fixing portion 333 , so that after the connecting pin 33 and the elastic connecting sleeve 51 are installed in place, the connecting pin 33 can be prevented from falling out under the vehicle vibration environment for a long time.

[0038] Elastic connecting sleeves 51 are set at both ends of the air guide cover 5, and the connecting pin 33 is pre-assembled with the filter assembly 3. The connecting pin 33 is inserted into the mounting hole 631 and the elastic connecting sleeve 51 to realize the assembly of the filter assembly 3. At the same time, the two ends of the air guide cover 5 are tightly connected to the filter assembly 3 to avoid the problem of loose sealing between the two.

[0039] As an example of the present invention, limiting edges 632 are provided at the upper and lower edges of mounting hole 631. Limiting edges 632 bend and extend toward the center of mounting hole 631. Limiting edges 632 limit the upper and lower edges of filter assembly 3, ensuring that filter assembly 3 is properly installed. The cooperation between limiting edges 632 and plug-in block 633 thus completely secures the perimeter of filter assembly 3, preventing filter assembly 3 from falling backward due to vibration during prolonged vehicle operation.

[0040] Preferably, the filter assembly 3 includes a filter 32 and an oil-absorbing layer 31. The filter 32 has a porous structure and is provided with folded edges 321 around the periphery of the filter 32. The folded edges 321 extend rearwardly, forming a storage space behind the filter 32. The oil-absorbing layer 31 is mounted within the storage space. Preferably, a fixed folded edge 322 is provided at the free end of the folded edge 321, extending toward the center of the filter assembly 3, to secure the oil-absorbing layer 31 and prevent it from falling off the filter assembly 3.

[0041] The oil-absorbing layer 31 is made of an oil-absorbing and breathable material and can be replaced regularly, effectively filtering oil droplets carried in the hot air and preventing a large amount of oil droplets from adhering to the filter mesh 32. Preferably, fixing seats 35 are provided at both ends of the filter mesh 32 for pre-assembly of the connecting pin 33, and corresponding portions of the oil-absorbing layer 31 are provided with clearance notches to allow clearance between the connecting pin 33 and the fixing seats 35.

[0042] As an example of the present invention, a hook 34 is further provided on the edge of the filter screen 32 for facilitating fixation when the filter screen assembly 3 is sprayed before assembly.

[0043] The elastic connecting sleeve 51 includes a first fixing portion 511, a first connecting portion 513, and an anti-slip portion 514, arranged in sequence from front to back. The first fixing portion 511, the first connecting portion 513, and the anti-slip portion 514 are integrally formed, with the first connecting portion 513 disposed between the first fixing portion 511 and the anti-slip portion 514. The outer diameter of the first fixing portion 511 is larger than that of the first connecting portion 513, and the outer diameter of the anti-slip portion 514 near the first connecting portion 513 is larger than that of the first connecting portion 513. An assembly hole 531 is provided at a corresponding position on the air scoop 5, and the first connecting portion 513 is snapped into the assembly hole 531, so that the first fixing portion 511 is located at the front side of the air scoop 5 and the anti-slip portion 514 is located at the rear side of the air scoop 5. Due to the material and structural design of the elastic connecting sleeve 51, the elastic connecting sleeve 51 is tightly connected to the air scoop 5, preventing the elastic connecting sleeve 51 from falling out of the air scoop 5.

[0044] As an example of the present invention, the air guide 5 includes a first inclined plate 53, with assembly holes 531 provided on both sides of the first inclined plate 53. The assembly holes 531 protrude toward the side away from the front plate 63 and include a vertically arranged bottom surface. One end of the elastic connecting sleeve 51 is inserted through the assembly hole 531, and the other end of the elastic connecting sleeve 51 is positionally assembled into the assembly hole 531. This arrangement allows the air guide 5 to be used to positionally limit the assembly of the elastic connecting sleeve 51, ensuring that the elastic connecting sleeve 51 is horizontal after installation. At the same time, the elastic connecting sleeve 51 can be used to assemble the filter assembly 3.

[0045] The inner front end of the first fixing part 511 of the elastic connecting sleeve 51 is set as an outward flaring structure, and the corresponding rear end of the head 334 of the connecting pin 33 is provided with a contracted inclined surface structure. When the connecting pin 33 is installed and inserted, the head 334 cooperates with the flaring structure of the first fixing part 511 to guide the connecting pin 33 to be smoothly inserted into the elastic connecting sleeve 51.

[0046] The inner rear end of the anti-slip portion 514 is also provided with an outwardly flared structure, the inner wall of which forms a wedge-shaped surface 512. After the head 334 of the connecting pin 33 is inserted into the anti-slip portion 514, it presses against the wedge-shaped surface 512 on the inner wall of the anti-slip portion 514, so that the inner wall of the anti-slip portion 514 tightly wraps around the head 334, preventing the head 334 from falling out of the anti-slip portion 514. When pulling out the connecting pin 33, it is necessary to use force to separate the head 334 from the anti-slip portion 514, preventing the filter assembly 3 from loosening due to vehicle vibrations, while also facilitating disassembly, cleaning, or replacement of the filter assembly 3.

[0047] The elastic connecting sleeve 51 is configured to be made of an elastic and deformable material. Preferably, the elastic connecting sleeve 51 is configured to be a silicone sleeve, which not only plays a sealing role in tight connection, but also has a certain vibration reduction effect to prevent the filter assembly 3 from vibrating and making noise.

[0048] As an example of the present invention, the air guide hood 5 includes a first inclined plate 53, a guide portion 54 is provided on the first inclined plate 53 at a position corresponding to the exhaust hole 621, first side edges 56 are provided on both sides of the first inclined plate 53, and a connecting foot 52 is provided on the first side edge 56 on the side away from the first inclined plate 53, and a connecting hole is provided on the connecting foot 52, and screws or other connecting parts are used to pass through the connecting hole to connect and fix the lower part of the air guide hood 5 to the top plate 62 to prevent the air guide hood 5 from shaking due to force, and at the same time prevent the air guide hood 5 from being unstable when the connecting pin 33 is inserted to install the filter assembly 3, affecting the installation of the filter assembly 3.

[0049] The lower end of the first inclined plate 53 is located at the rear side of the exhaust hole 621, and the upper end of the first inclined plate 53 is provided with a first flange 57. The first flange 57 is in contact with the front plate 63, so that the air guide cover 5 as a whole forms a structure inclined forward from bottom to top, guiding the hot air upward and forward to be discharged through the filter assembly 3.

[0050] The vehicle-mounted microwave oven also includes a shell 1, a door assembly 2, and a control panel 4. The inner pot 6 is located in the shell 1, and one side of the door assembly 2 is hingedly connected to the shell 1 for selectively blocking the inner pot 6; the control panel 4 is located on one side of the door assembly 2, and an electrical cavity is provided on one side of the inner pot 6 at a position corresponding to the control panel 4. The specific assembly structure is prior art and will not be described in detail here.

[0051] Preferably, the inner container 6 is provided with a first air inlet 641 on a side adjacent to the electrical cavity, and a fan assembly 7 is provided on the rear side of the electrical cavity for delivering air into the electrical cavity and the inner container 6. As an example of the present invention, the inner container 6 includes a rear plate 61, and the fan assembly 7 is fixedly mounted on the rear plate 61. The fan assembly 7 includes a second fan and a first fan arranged in an upper and lower arrangement, with the first fan located on the outer side of the rear plate 61 and the second fan located on the inner side of the rear plate 61.

[0052] This setting can ensure that the first fan and the second fan have similar wind pressure, and ensure that the operating power of the two and the airflow blowing into the electrical cavity are basically the same; at this time, the distance between the first fan and the frequency conversion board 9 is large, which can meet the detection requirements of the vehicle-mounted microwave oven in the temperature rise experiment.

[0053] As an example of the present invention, a waveguide box is provided on the top of the inner tank 6, one end of the waveguide box extends into the electrical cavity, a magnetron 8 and a frequency conversion board 9 are provided in the electrical cavity, the magnetron 8 is located on the upper side of the frequency conversion board 9 and is fixedly connected to the waveguide box, a filter plate 10 is provided on the top of the inner tank 6, and the filter plate 10 is located on the side of the inner tank 6 away from the electrical cavity.

[0054] This arrangement fully utilizes the interior space of the vehicle-mounted microwave oven while preventing EMC signal interference from the filter board 10 on the inverter board 9. No other electronic components are placed between the fan assembly 7 and the inverter board 9, ensuring that the vehicle-mounted microwave oven meets temperature rise requirements in extreme summer temperatures and enabling further size reduction. Preferably, the magnetron 8 is provided with a first bracket 11 on the side away from the inner container 6, and the first bracket 11 is fixedly connected to the housing 1. This arrangement further improves the assembly stability and reliability of the magnetron 8, ensuring its service life in a vehicle-mounted environment.

[0055] Example 2

[0056] Microwave ovens typically have a manual or push-button door opening mechanism. Users can open the door in one step by pulling the door handle or pressing the door opening button, which is convenient. However, there is also a risk of burns from the hot gas or food inside if the door is opened by mistake, especially in a vehicle. Therefore, the applicant proposes the following solution based on Example 1:

[0057] A vehicle-mounted microwave oven includes a door hook 21 and a switch assembly 12. The door hook 21 is rotatably arranged on the door assembly 2, and the switch assembly 12 is used to selectively limit the door hook 21; the switch assembly 12 includes an electromagnet 122, and the electromagnet 122 is provided with a limiting shaft 1221 on a side close to the door hook 21. The limiting shaft 1221 is electrically connected to the control panel 4 and is used to selectively limit the door hook 21.

[0058] When opening the door, the limit shaft 1221 is first controlled to move telescopically to remove the limit on the door hook 21. Then, the micro switch 124 and the connecting rod 123 cooperate to activate the door hook 21 and finally open the door assembly 2. This configuration effectively prevents the door assembly 2 from opening due to accidental touch, prevents microwave leakage, and improves user safety.

[0059] Preferably, the switch assembly 12 includes a bracket 121, which is disposed on one side of the inner container 6. The electromagnet 122 is disposed between the bracket 121 and the inner container 6. The side wall of the limit shaft 1221 can selectively abut against the door hook 21. This arrangement is simple in structure, and the limit shaft 1221 abuts against the door hook 21 to achieve position limiting. The limit shaft 1221 is controlled to extend and retract via the membrane switch and the control panel 4.

[0060] As an example of the present utility model, the switch assembly 12 also includes a connecting rod 123 and a micro switch 124 arranged on the bracket 121, and the micro switch 124 is provided with a contact. One end of the connecting rod 123 is rotatably arranged on the bracket 121, and the two sides of the connecting rod 123 are respectively provided with a first touch part and a second touch part corresponding to the door hook 21 and the contact. The distances from the first touch part and the second touch part to the first end of the connecting rod 123 are L1 and L2 respectively, where L1 is less than L2. The contact can move synchronously with the door hook 21 through the connecting rod 123 and activate the micro switch 124.

[0061] This setting can effectively reduce the movement stroke of the door hook 21 during the process of opening the oven door and before the microwave oven is powered off, while satisfying the movement stroke of the contacts on the microswitch 124 and enabling the microswitch 124 to operate and control the power off of the microwave oven. This reduces the amount of microwave leakage when the oven door is opened, and further reduces the harm of microwave leakage to the human body.

[0062] Although the present invention is disclosed as above, it is not limited thereto. Any person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope defined by the claims.
