[0003] This dual-zone oven requires different electronic touch switches for different ovens. The electronic touch switches are expensive to manufacture, and the electronic touch screen occupies a large area, making them inconvenient to set up. Moreover, when the entire oven zone needs to be working, both electronic touch switches need to be operated simultaneously, which is cumbersome. Summary of the Invention

[0004] The purpose of this patent is to provide a more streamlined dual-zone oven control mechanism and oven.

[0005] The purpose of this patent is achieved as follows: a dual-zone oven control mechanism, comprising:

[0006] The box has an inner liner for placing and heating items, and a door is provided on one side of the box.

[0007] A partition, disposed within the inner liner, divides the inner liner into a first region and a second region, both regions being equipped with identical functional components; and

[0008] The main switch and the auxiliary switch each have several positions, and the auxiliary switch has a default position. When the auxiliary switch is in the default position, the position of the main switch can control the same functional components in the first area and the second area to work or stop synchronously. The other positions of the auxiliary switch can independently control the functional components in the first area to work.

[0009] Furthermore, the functional components include heating components; when the auxiliary switch is in the default position, the position of the main switch can control the heating components in the first area and the second area to work synchronously or stop; the auxiliary switch has a baking position, which can control the heating components in the first area to work.

[0010] Furthermore, it also includes a main temperature control switch and an auxiliary temperature control switch that are respectively connected to the main switch and the auxiliary switch. When the auxiliary switch is in the default position, the main temperature control switch can control the heating temperature of the heating components in the first and second regions. The auxiliary temperature control switch is used to control the heating temperature of the heating components in the first region when the auxiliary switch is in the baking position.

[0011] Furthermore, the auxiliary switch has a third control point and a fourth control point. The third control point is connected to the main temperature control switch and the heating component in the first area, and is used to control the heating temperature of the heating components in the first and second areas through the main temperature control switch when the auxiliary temperature control switch is not in the baking position. The fourth control point is connected to the auxiliary temperature control switch and the heating component in the first area, and is used to control the heating temperature of the heating component in the first area through the auxiliary temperature control switch when the auxiliary switch is in the baking position.

[0012] Furthermore, the functional components also include lighting components and ventilation components; when the auxiliary switch is in the default position, the position of the main switch can control the lighting components and ventilation components in the first area and the second area to work synchronously or stop; the auxiliary switch has a defrost position, which can control the lighting components and ventilation components in the first area to work.

[0013] Furthermore, the auxiliary gear switch is connected to the functional components in the first area, and the main gear switch is connected to the functional components in the second area and the auxiliary gear switch respectively, for controlling the operation of the functional components in the second area, and cooperating with the auxiliary gear switch to control the operation of the functional components in the first area.

[0014] Furthermore, the main gear switch is provided with a first control point and a second control point, which are used to turn the first control point and the second control point on or off by switching the gear of the main gear switch. The first control point and the second control point are both connected to the functional components and the auxiliary gear switch in the second area.

[0015] Furthermore, both the main gear switch and the auxiliary gear switch are rotary switches. Each rotary switch has several pins, which are used to trigger different pins by rotating at different angles to switch different gears.

[0016] An oven comprising the aforementioned dual-zone oven control mechanism.

[0017] The outstanding and beneficial technical effects of this patent compared to existing technologies are:

[0018] 1. This patent realizes the control logic of a dual-zone oven by setting multiple gear switches. Compared with the existing electronic control method, its overall structure is more streamlined and easier to set up. At the same time, it reduces the installation space required for control, making the layout of the oven or integrated stove more flexible.

[0019] 2. Since the oven in this patent is a dual-zone oven, it can operate in both zones separately or as a single zone. Therefore, a main switch and an auxiliary switch are provided. The main switch is used for single-zone control after integration, and the main switch and auxiliary switch are used in combination for separate control of the two zones. Overall, it is more in line with the user's usage habits.

[0035] The present patent will be further described below with reference to specific embodiments:

[0036] A dual-zone oven control mechanism is provided. In this embodiment, the dual-zone oven control mechanism described in this patent is used in an oven, which can be installed in an integrated stove or used independently.

[0037] Specifically, it includes a housing 1, inside which is an inner liner 11 for placing and heating items, and a door 12 is rotatably mounted on one side of the housing 1. For example... Figure 1 As shown, the inner liner 11 is fixed inside the box 1, and a door 12 is hinged to the box 1 via a hinge structure, which enables the door 12 to rotate.

[0038] The inner liner 11 is generally rectangular, and a detachable partition 9 is provided inside the rectangular inner liner 11 to divide the inner liner 11 into a first region 21 and a second region 22. Several functional components are arranged in both the first region 21 and the second region 22. In this embodiment, the first region 21 and the second region 22 are respectively arranged vertically.

[0039] Specifically, such as Figure 2 As shown, the functional components can be a heating component 3, a ventilation component 4, and a lighting component 5. The heating component 3 is specifically an electric heating wire fixed to the back of the inner liner 11. Two heating wires are provided, located on the back of the first region 21 and the second region 22, respectively. Similarly, two ventilation components 4 and two lighting components 5 are provided. The ventilation component 4 is a fan, and the lighting component 5 is a lamp, located in the first region 21 and the second region 22, respectively. The heating component 3 is used to realize the heating action of the oven, the ventilation component 4 is used to circulate air inside the oven to assist in its operation, and the lamp allows the user to observe the internal workings of the oven.

[0040] Furthermore, the gear switch includes a main gear switch 7 and an auxiliary gear switch 8, both of which have several gear positions. The auxiliary gear switch 8 has a default gear position. When the auxiliary gear switch 8 is in the default gear position, the gear position of the main gear switch 7 can control the same functional components in the first region 21 and the second region 22 to work synchronously or stop. The other gear positions of the auxiliary gear switch 8 can independently control the functional components in the first region 21 to work.

[0041] The auxiliary gear switch 8 has a default gear, a baking gear, and a defrosting gear corresponding to the heating component 3, the ventilation component 4, and the lighting component 5, respectively.

[0042] like Figure 3-5 As shown, the main gear switch 7 is provided with at least a first control point 71 and a second control point 72, which are used to connect or disconnect the first control point 71 and the second control point 72 by switching the gear of the main gear switch 7. The first control point 71 and the second control point 72 are respectively connected to the functional components in the first area and the auxiliary gear switch 8.

[0043] like Figure 3-5 As shown, Figure 2 This is the control circuit diagram for the gear switch in this patent. Figure 4 , 5 The schematic diagram shows the main switch 7 and the auxiliary switch 8. Both are rotary switches. The main switch 7 has pins P1, P3, 1, and 5. Pins P1 and 1 are connected to form the first control point 71, and pins P3 and 5 form the second control point 72. The auxiliary switch 8 has pins P1, P2, P3, P4, P5, P6, P7, 1, 2, 3, 4, 5, 6, and 7. It should be noted that the main switch 7 and the auxiliary switch 8 have internal circuits. Depending on actual needs, the main switch 7 and the auxiliary switch 8 can each obtain three positions: 0, 1, and 2. The three positions 0, 1, and 2 on the auxiliary switch 8 correspond to the default position, the baking position, and the defrosting position, respectively.

[0044] In this embodiment, the first control point 71 and the second control point 72 are both connected to the functional components and the auxiliary gear switch 8 in the second region 22.

[0045] like Figure 3 As shown, Figure 3The circuit diagram for this patent shows a live wire and a neutral wire on the left side. The live wire is connected to pins P1 and P3 of the main gear switch 7 via a short-circuit protector. A wire is led out from pin P1 to pins P5 and P7 of the auxiliary gear switch 8. The heating component 3, ventilation component 4, and lighting component 5, located in the first region 21, are connected in parallel to pins 1, 4, and 5 of the auxiliary gear switch 8. Wires are then led out from the other ends of the heating component 3, ventilation component 4, and lighting component 5 to connect to the neutral wire. The main switch 7 has pin 5 connected to the ventilation assembly 4 and lighting assembly 5 in parallel in the second area 22, and also connected to pins P3 and P6 of the auxiliary switch 8. Pin 1 of the main switch 7 is connected to the main temperature control switch 61, which in turn connects to the heating assembly 3 in the first area 21, and simultaneously to pin P2 of the auxiliary switch 8 via a wire. The other ends of the heating assembly 3, ventilation assembly 4, and lighting assembly 5 in the second area 22 are connected to the neutral wire via wires. It should be noted that the auxiliary switch 8 has interconnected pins to achieve the control of the oven in this patent.

[0046] In fact, the auxiliary switch 8 has a third control point 81 and a fourth control point 82. The third control point 81 is connected to the main temperature control switch 61 and the heating component 3 in the first region 21. When the auxiliary temperature control switch 62 is not in the baking position, the main temperature control switch 61 controls the heating temperature of the heating component 3 in the first region 21 and the second region 22. The fourth control point 82 is connected to the auxiliary temperature control switch 62 and the heating component 3 in the first region 21. When the auxiliary switch 8 is in the baking position, the auxiliary temperature control switch 62 controls the heating temperature of the heating component 3 in the first region 21.

[0047] like Figure 2 As shown, the third control point 81 is from pin P2 of the auxiliary gear switch 8 to pin 2 of the auxiliary gear switch 8, and the fourth control point 82 is from pin P7 of the auxiliary gear switch 8 to pin 7 of the auxiliary gear switch 8 and from pin P1 of the auxiliary gear switch 8 to pin 1 of the auxiliary gear switch 8.

[0048] like Figure 6 As shown, when the main gear switch 7 is in the 0 position, the P1 pin and P3 pin of the main gear switch 7 are directly connected, the P1 pin and the 1 pin are not connected, and the P3 pin and the 5 pin are not connected, which causes the functional components in the second area 22 to not work. At this time, the functional components in the first area 21 are controlled to work by making different pins within the auxiliary gear switch 8 conduct.

[0049] Specifically, when the auxiliary switch 8 is in position 0, i.e., the default position, pins P2-2, P3-3, and P6-6 are conducting. At this time, all functional components are short-circuited, and the entire oven is in a stopped state; for example... Figure 6 As shown, when the auxiliary switch 8 is in position 1, i.e., the defrost position, pins P4-4 and P5-5 are conducting. At this time, the lighting component 5 and ventilation component 4 in the first area 21 move. Defrosting can be performed in this state, i.e., placing a frozen object in the first area 21 to defrost it. In the following text, the synchronized movement of the lighting component 5 and ventilation component 4 will be referred to as the defrost action. Figure 7 As shown, when the auxiliary switch 8 is in position 2, i.e., the baking position, pins P1-1, P4-4, P5-5, and P7-7 are connected, meaning the fourth control point 82 is activated. At this time, the heating element 3, lighting element 5, and ventilation element 4 in the first area 21 are all operational, allowing food to be baked and the oven to function. Temperature can also be controlled via the auxiliary temperature control switch 62. In the following text, the synchronized movement of the heating element 3, lighting element 5, and ventilation element 4 will be referred to as the baking action.

[0050] Furthermore, the remaining positions of the main switch 7 are used to control the movement of functional components throughout the inner liner 11, such as... Figure 8 , 9 As shown, when the auxiliary gear switch is in position 0, i.e. the default position, when the main gear switch 7 switches between positions 1 and 2, in position 1, pin P3-5 is turned on, which can control the lighting component 5 and ventilation component 4 in the first area 21 and the second area 22 to work. In position 2, pins P1-1 and P3-5 are turned on, which can control the heating component 3, lighting component 5 and ventilation component 4 in the first area 21 and the second area 22 to work. At this time, the third on / off part 81 in the auxiliary gear switch 8 is turned on, and the auxiliary temperature control switch 62 is not working. The temperature of the heating component 3 in the first area 21 and the second area 22 can be controlled simultaneously by the main temperature control switch 61, thereby realizing the control of the entire area of ​​the inner liner 11 by a single switch of the main gear switch 7.

[0051] When the main gear switch 7 is in position 1 or 2, the auxiliary gear switch 8 can be switched to enable different actions in the first region 21 and the second region 22, such as... Figure 10 , 11As shown, taking the main gear switch 7 in position 1 as an example, if the auxiliary gear switch 8 is switched to position 1, the P4-4 and P5-5 pins of the auxiliary gear switch 8 are turned on. At this time, the lighting component 5 and ventilation component 4 in the first area 21 are working, as are the lighting component 5 and ventilation component 4 in the second area 22. When the auxiliary gear switch 8 is switched to position 2, its P1-1, P4-4, P5-5 and P7-7 pins are turned on. At this time, the heating component 3, lighting component 5 and ventilation component 4 in the first area 21 are working, as are the lighting component 5 and ventilation component 4 in the second area 22. This is how the auxiliary gear switch 8 controls a single area.

[0052] like Figure 12 As shown, this patent allows the main temperature control switch 61 and the auxiliary temperature control switch 62 to control the temperature of the two heating components 3 respectively by switching between the third control point 81 and the fourth control point 82. Figure 12 This is a circuit diagram when the main switch 7 and the auxiliary switch 8 are both in position 2, i.e., when both the main switch 7 and the auxiliary switch 8 are in the baking position. The functional components in the second region 22 are normally controlled by the main switch 7. However, in the auxiliary switch 8, the third control point 81 (P2-2 pin), which is connected to the main temperature control switch 61, is disconnected, while the fourth control point 82 (P7-7 and P1-1 pins) is connected. At this time, the connection between the main temperature control switch 61 and the heating component 3 in the second region 22 is broken, while the auxiliary temperature control switch 62 is connected to the heating component 3 in the second region 22. This allows the main temperature control switch 61 and the auxiliary temperature control switch 62 to control the two heating components 3 respectively.

[0053] The specific working mode can be found in the table below:

[0054]

[0055] In other embodiments, the number of gear switches can be appropriately increased according to the different functional components to increase the combination quantity and meet different user needs.

[0056] In summary, this patent implements the control logic of a dual-zone oven by setting multiple speed switches. Compared to existing electronic control methods, its overall structure is more streamlined and easier to set up, while also reducing the installation space required for control, making the layout on the oven or integrated stove more flexible. Furthermore, this patent reduces the difficulty of control and makes it easier for users by setting a neutral position in the main speed switch 7 to control a single oven independently.

[0057] Furthermore, it also includes an auxiliary temperature control switch 62, which is connected to the main switch 7 and the auxiliary switch 8 located in the first region 21 and the second region 22, respectively. The main temperature control switch 61 can control the heating temperature of the heating component 3 in the first region 21 and the second region 22. The auxiliary switch 8 is used to control the heating temperature of the heating component 3 in the first region 21 when the auxiliary switch 8 is in the baking position.

[0058] like Figure 2 As shown, the main temperature control switch 61 is connected to the heating components in the second region 22 via wires, and is also connected to the P2 pin of the auxiliary position switch 8 via wires. (Reference) Figure 9 The main gear switch 7 is in position 2, and the auxiliary gear switch 8 is in the default position. At this time, pins P2 and P1 of the auxiliary gear switch 8 are connected. Since pins P2 and P1 of the auxiliary gear switch 8 are connected, and pin P1 is connected to the heating element 3 in the first region 21, the main temperature control switch 61 simultaneously controls the temperature of the heating element 3 in both the first region 21 and the second region. (Reference) Figure 11 When the main gear switch 7 is in position 1 and the auxiliary gear switch 8 is in the default position, the P2 pin of the auxiliary gear switch 8 is not energized. The live wire enters directly from the P7 pin of the auxiliary gear switch 8 and is connected in series with the 7 pin of the auxiliary gear switch 8, the auxiliary temperature control switch 62, the P1 pin of the auxiliary gear switch 8, and the 1 pin of the auxiliary gear switch 8 to the heating component 3 in the first area 21. This allows the heating temperature of the heating component 3 in the first area 21 to be controlled by the auxiliary temperature control switch 62.

[0059] In other embodiments, the first region 21 and the second region 22 can also be set to the left and right respectively, or to be set diagonally, as long as they are connected to the machine.

[0060] The above embodiments are merely preferred embodiments of this patent and are not intended to limit the scope of protection of this patent.
