Background technique

In the related art, the landing system of the microwave processing device requires an operator to manually adjust its mechanical structure before each time food is heated, which is time-consuming and labor-intensive. And the microwave processing device (mostly used in commercial places) is defined as a commercial heating furnace, and its use environment requires frequent manual operations by operators. Due to the high temperature of the heating plate, the operator may be burned with each operation; frequent use may cause the operator to misuse and cause the food to fail to heat.

Most microwave ovens on the market are passively protected against no-load problems. The microwave oven cannot be terminated before no-load occurs. Instead, the oven ’s thermostat detects that the temperature exceeds the pre- Set the standard, the thermostat is disconnected, thus disconnecting the microwave work. This method may cause damage to other components of the microwave equipment, such as the temperature of some components exceeds the standard, shortening the service life. It can also cause problems such as focus, fatal damage to the equipment, and even safety issues. Specifically, a thermostat is installed on a cavity of a general device, and the thermostat is installed on a main circuit of a microwave electrical circuit. When no-load occurs for a certain period of time, the temperature of the cavity of the device rises, and the thermostat is disconnected. Disconnect the microwave to work.

When the cover 11 is closed, a closed cooking cavity 101 can be formed between the cover 11 and the base 12, and food can be placed in the cooking cavity 101 for cooking. Each time the food is heated, the cover 11 needs to be opened, the food to be heated is placed in the cooking cavity 101, and then the oven door is closed.

The tray 4 is movably provided in the cooking cavity 101 in the vertical direction. The tray 4 can be moved up and down along the cooking cavity 101, so that the cooking cavity 101 becomes a cavity with a variable volume, so that it can be used to heat food of different heights. In addition, it can be understood that the position of the tray 4 is adjusted according to the height of the food, so that the tray 4 is close to the food. The tray 4 is provided with a first heating element 20, which can make full use of the heat emitted by the first heating element 20, and the food can Quickly heated. In addition, the heat emitted by the first heating element 20 can be used to heat the cooking cavity 101 so that the temperature of the cooking cavity 101 reaches a temperature suitable for cooking food. Because the volume of the cooking cavity 101 can be adjusted according to the height of the food to be heated, The accommodating cavity can be quickly heated to avoid waste of energy and reduce costs.

The connecting member 30 is connected to the tray 4. Wherein, the tray 4 is accommodated in the cooking cavity 101, and the connecting piece 30 is connected to the tray 4 and extends out of the accommodating cavity. The user can adjust the height of the tray 4 through the connecting piece 30.

The positioning member 40 is movably disposed on the body 10 between the positioning position and the release position. The positioning member 40 positions the connection member 30 at the positioning position, and the positioning member 40 releases the connection member 30 at the release position. That is, the positioning member 40 can be used to position the connection member 30. Since the connection member 30 is connected to the tray 4, the tray 4 can be moved up and down along the cooking cavity 101, that is, the positioning member 40 can adjust the tray by positioning and releasing the connection member 30 4 height.

The driving member 50 is connected to the positioning member 40, and the driving member 50 drives the positioning member 40 to move. In this way, the driving member 50 drives the positioning member 40 to move between the release position and the positioning position. When the positioning member 40 is in the positioning position, the tray 4 is positioned, and when the positioning member 40 is in the release position, the tray 4 is released. Thus, the height of the tray 4 can be adjusted by the driver 50.

In the related art microwave processing device 100, after cooking is completed, the operator needs to manually adjust the height of the tray 4, and the operator is also required to take out the food. Especially in a commercial environment, the work is frequent and it is prone to misoperation. Causes burns and fatigue to the operator.

The microwave processing apparatus 100 in the present application actively adjusts the height of the tray 4 through the driving member 50, which reduces the workload of the operator, and can avoid the fatigue and misoperation of the operator during a long-term operation process, and avoid the user being Tray 4 burns.

Therefore, according to the microwave processing apparatus 100 of the embodiment of the present invention, the microwave processing apparatus 100 has a driving member 50. The driving member 50 can drive the positioning member 40 to adjust the height of the tray 4, which can reduce operation steps and improve the efficiency of food production.

In some embodiments, as shown in FIG. 4 in combination with FIG. 5, FIG. 6, and FIG. 7, the positioning member 40 includes a locking pin 41. As shown in FIG. 16 and FIG. When the positioning member 40 is located at the positioning position, the locking pin 41 is inserted into at least one of the locking slots 311 to position the connecting member 30. When the positioning member 40 is located at the releasing position, the locking slot 311 is separated from the plurality of locking slots 311.

In other words, when the tray 4 needs to be fixed, the bayonet 41 is inserted into the bay 311, and the cooperation of the bayonet 41 and the bay 311 can be used to fix the bay 4, and at this time, the user does not need to hold the connection piece 30; the bay needs to be adjusted. At the 4 position, the latch 41 is pulled out from the slot 311, and the user holds the connecting piece 30 to adjust the height of the tray 4. Among them, one or more bayonet pins 41 may be used. In this way, when the tray 4 is fixed, one bayonet 41 may be inserted into the bay 311, or a plurality of bayonet 41 may be inserted into the same bay or different bays 311. This makes the position of the tray 4 more stable.

In some specific embodiments, as shown in FIG. 4, FIG. 5, and FIGS. 16 and 17, the connecting member 30 is provided with a limiting portion 312. In a top-to-bottom projection, at least a portion of the latch 41 is limited by the limiting portion 312. Covering, the limiting portion 312 is provided at least one of above and below the plurality of card slots 311.

When the user holds the connecting piece 30 to lift the tray 4 upward, if the force is too strong, the latch 41 will also contact the limiting portion 312 located below the slot 311 to prevent the upper portion of the tray 4 from colliding with the inner wall of the cooking cavity 101. That is, the cooperation of the latch 41 and the limiting portion 312 plays a limiting role.

In a specific embodiment, as shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5, and FIG. 16 and FIG. 17, the connecting member 30 is in the shape of a rod extending in the up-down direction. A groove 31 is formed, and upper and lower sides of the groove 31 respectively form a limiting portion 312, and a plurality of clamping grooves 311 are formed on the bottom surface of the groove 31. In other words, a groove 31 is provided on the outer peripheral surface of the connecting member 30. The groove 31 extends along the axial direction of the connecting member 30. A plurality of latching grooves 311 are formed on the bottom surface of the groove 31. The first and second sides opposite to each other in the axial direction of 30, and the upper and lower sides opposite to each other. The upper and lower sides are formed as limiting portions 312. At least a part of the latch 41 is always located on the first and second sides. In between, the limiting portion 312 is provided at least one of the upper top surface and the lower top surface of the limiting groove. In this way, the formation of the limiting portion 312 is simple, the limiting portion 312 and the connecting member 30 have an integrated structure, and the processability is good.

In some embodiments, as shown in FIG. 6 in combination with FIG. 2, FIG. 3, FIG. 4, and FIG. 5, the positioning member 40 further includes a guiding member 42 mounted on the body 10, and the guiding member 42 is provided with a guiding groove 43. The bayonet pin 41 movably penetrates the guide groove 43. The bayonet 41 penetrates the guide groove 43, and the bayonet 41 moves between the positioning position and the release position along the guide groove 43, that is, the guide 42 plays a guiding role to prevent the bayonet 41 from appearing after a long time insertion Dislocation makes the structure stable.

Further, as shown in FIG. 2, FIG. 3, FIG. 4, FIG. 5, FIG. 6 and FIG. 7, the bayonet pin 41 has a mounting groove extending in a direction closer to and away from the connecting member 30, and the connecting groove is adjacent to the connecting member. 30 is provided with a guide bar 411 at one end, and a return spring 53 is installed in the mounting groove. One end of the return spring 53 is sleeved on the guide bar 411 and abuts against the latch 41, and the other end of the return spring 53 is abutted against the guide 42. The latch 41 is provided with a mounting groove, and a return spring 53 is provided in the mounting groove. One end of the guide bar 411 projects into the return spring 53. The guide bar 411 can play a guiding role during the expansion and contraction of the return spring 53. It can also ensure the stable installation of the spring.

Among them, as shown in FIGS. 4, 5, 6, and 7, one end of the return spring 53 connected to the guide bar 411 abuts on the latch 41, and the other end of the return spring 53 remote from the guide bar 411 abuts. The guide 42 is connected and fixed to the body 10. In this way, when the latch 41 moves from the positioning position to the release position under the action of the driving member 50, the return spring 53 is compressed and stores energy, and the return spring 53 acts as a buffer; when the latch 41 moves from the release position to the positioning position The reset spring 53 releases energy and returns to the initial state. The reset spring 53 drives the latch 41 to move from the released position to the positioning position, and the automatic reset of the latch 41 can be realized. At this time, the reset can be completed without driving by the driver 50. That is to say, the return spring 53 has a force that always drives the bayonet 41 into the bay 311. After the height of the bay 4 is adjusted, the bayonet 41 automatically positions the bay 4 to save the operation steps of the operator.

In some embodiments, as shown in FIG. 1, FIG. 2, FIG. 3, FIG. 4, FIG. 5 and FIG. 6, a handle 80 is provided on the positioning member 40. A handle 80 is provided on the positioning member 40, and the user can manually control the latch 41 to move between the release position and the positioning position through the handle 80. In this way, it can be ensured that the positioning of the tray 4 can be achieved when the driving member 50 cannot work normally. The handle 80 may be integrally formed with the positioning member 40, fixedly connected or detachably connected. For example, the handle 80 may be detachably connected to the positioning member 40. The handle 80 and the positioning member 40 may be screwed, specifically, The lower end of the handle 80 has an external thread, the positioning member 40 has a threaded hole, and the outer periphery of the threaded hole has an internal thread that is compatible with the external thread. Cooperate with internal thread.

In some embodiments, as shown in FIG. 6, the driving member 50 includes a transmission portion 51, a driving portion 52, and a reset member.

Among them, the driving portion 52 is used to provide power, the transmission portion 51 is used to transmit power to the positioning member 40, and the resetting member is used to reset the positioning member 40.

Specifically, as shown in FIG. 6, FIG. 8, and FIG. 9, the transmission portion 51 is provided with a plurality of first convex teeth 511 at intervals in the circumferential direction. The driving portion 52 is connected to the transmission portion 51 to drive the transmission portion 51 to rotate. The first convex teeth 511 are adapted to push the positioning member 40 to move to the release position.

It can be understood that the driving portion 52 drives the transmission portion 51 to rotate. The periphery of the transmission portion 51 has a plurality of first convex teeth 511 arranged at intervals. During the rotation of the transmission portion 51, the first convex teeth 511 and the positioning member 40 are intermittent. During sexual contact, when the first convex tooth 511 is in contact with the positioning member 40, the positioning member 40 is pushed, and when the vertex of the first convex tooth 511 is in contact with the positioning member 40, the positioning member 40 is located at the extreme position of the release position. When the first convex tooth 511 is not in contact with the positioning member 40, the positioning member 40 is released, so that the transmission portion 51 rotates once, and the height of the tray 4 can be adjusted multiple times.

Among them, the reset member often has a force for driving the positioning member 40 to move to the positioning position. When the positioning member 40 moves from the release position to the positioning position, the reset member releases energy and returns to the initial state. The reset member drives the positioning member 40 to move from the release position to the positioning position, and the automatic resetting of the positioning member 40 can be achieved. At this time, the driving member 50 is not required. The driver can complete the reset. In other words, the resetting member has a force that always drives the latch pin 41 to be inserted into the slot 311. After the height of the tray 4 is adjusted, the positioning member 40 automatically positions the tray 4 to save the operation steps of the operator.

In some embodiments, as shown in FIGS. 6 and 8, the driving member 50 further includes a mating portion 54. The engaging portion 54 is fixed on the positioning member 40. The engaging portion 54 is provided with a convex portion 541 protruding toward the connecting member 30. The convex portion 541 is connected to the plurality of first convex teeth 511, and the convex portion 541 is selected when the transmission portion 51 rotates The first convex teeth 511 are abutted or inserted between the two first convex teeth 511. When the first convex tooth 511 is in contact with the convex portion 541, the first convex tooth 511 pushes the engaging portion 54 having the convex portion 541 to move outward, and the positioning member 40 fixedly connected to the engaging portion 54 is also driven by the engaging portion 54. Move outside. When the convex portion 541 is inserted between two adjacent first convex teeth 511, the convex portion 541 no longer receives the pushing force from the first convex teeth 511, and the positioning member 40 moves inward under the action of the reset member.

That is, when the convex portion 541 and the first convex tooth 511 start to abut until the vertex of the convex portion 541 contacts the vertex of the first convex tooth 511, the positioning member 40 moves from the positioning position to the extreme position of the release position; the convex portion 541 During the process of contacting the apex of the first convex tooth 511 with the apex of the first convex tooth 511 until the convex portion 541 is separated from the first convex tooth 511, the positioning member 40 moves from the extreme position of the release position toward the connecting member 30.
