Description

Technical Field

[0001] This application relates to the field of kitchenware technology, and in particular to ovens. Background Technology

[0002] Ovens typically consist of an upper heating element and a lower heating element. The upper heating element is positioned near the top wall of the oven cavity, while the lower heating element is positioned near the bottom wall. In traditional ovens, the heating elements and the food support components (such as baking trays, racks, and rotisserie forks) are usually fixed in place. Since the heating elements and food support components are relatively stationary, there is often a significant difference in baking results between the top and bottom of the food (with the greatest difference between the top and bottom sides). This leads to uneven browning and a poor texture. Utility Model Content

[0003] Therefore, it is necessary to provide an oven to address the aforementioned problems.

[0004] To address the above problems, this application provides the following technical solution:

[0005] An oven comprising:

[0006] The inner liner has a top wall and a bottom wall;

[0007] The upper heating element is positioned close to the top wall;

[0008] The lower heating element is located close to the bottom wall;

[0009] An installation rod is fixed to the inner liner, and the angle between the length direction of the installation rod and the vertical direction is less than 45°.

[0010] A first press switch and a second press switch are both disposed on the mounting rod; the first press switch is located above the second press switch, and the distance between the first press switch and the second press switch along the length direction of the mounting rod is D; one of the first press switch and the second press switch is electrically connected to the upper heating tube, and the other is electrically connected to the lower heating tube; when the first press switch is pressed and the second press switch is reset, the upper heating tube is working and the lower heating tube is off; when the first press switch is reset and the second press switch is pressed, the upper heating tube is off and the lower heating tube is working.

[0011] A pressing element is slidably connected to the mounting rod. Both the first and second pressing switches are located on the sliding path of the pressing element so that they can be pressed by the pressing element. The dimension of the pressing element along the length of the mounting rod is L, and L and D satisfy: L < D; and

[0012] A food carrier is fixedly connected to the pressing member; the food carrier is located inside the inner liner and between the upper heating tube and the lower heating tube.

[0013] This oven has at least the following beneficial effects:

[0014] Because L < D, the pressing component cannot simultaneously press the first and second pressing switches. In other words, the pressing component can only press one of the first and second pressing switches at a time. When the pressing component slides upward to the first pressing switch, the first pressing switch is pressed, and the second pressing switch has been reset. The upper heating element is activated, and the lower heating element is deactivated. At this time, the food carrier moves closer to the upper heating element as the pressing component moves upward. When the pressing component slides downward to the second pressing switch, the second pressing switch is pressed, and the first pressing switch has been reset. The upper heating element is deactivated, and the lower heating element is activated. At this time, the food carrier moves closer to the lower heating element as the pressing component moves downward. During the baking process in this oven, when it is necessary to improve the baking effect of the upper part of the food, the pressing part can be slid to the first pressing switch, so that the food carrier is close to the upper heating element, the upper heating element is turned on and the lower heating element is turned off, thereby baking the upper part of the food; when it is necessary to improve the baking effect of the lower part of the food, the pressing part can be slid to the second pressing switch, so that the food carrier is close to the lower heating element, the upper heating element is turned off and the lower heating element is turned on, thereby baking the lower part of the food. Repeating the above process can make the baking effect of the upper and lower parts of the food consistent, can make the food evenly browned, and can improve the taste of the food.

[0015] In one embodiment, both the first and second push switches are normally open buttons, the first push switch is connected in series with the upper heating element, and the second push switch is connected in series with the lower heating element.

[0016] With this configuration, when the pressing element slides upward to the first pressing switch, the first pressing switch is pressed and closed, energizing the upper heating element, while the second pressing switch is reset and open, turning off the lower heating element. When the pressing element slides downward to the second pressing switch, the second pressing switch is pressed and closed, energizing the lower heating element, while the first pressing switch is reset and open, turning off the upper heating element.

[0017] In one embodiment, both the first and second push switches are normally closed buttons, the first push switch is connected in series with the lower heating element, and the second push switch is connected in series with the upper heating element.

[0018] With this configuration, when the pressing element slides upward to the first pressing switch, the first pressing switch is pressed and is in the off state, the lower heating element is turned off, and the second pressing switch has been reset and is in the closed state, energizing the upper heating element. When the pressing element slides downward to the second pressing switch, the second pressing switch is pressed and is in the off state, the upper heating element is turned off, and the first pressing switch has been reset and is in the closed state, energizing the lower heating element.

[0019] In one embodiment, the pressing element is sleeved on the mounting rod and conforms to the shape of the mounting rod.

[0020] This design helps ensure that the pressing component slides along the length of the mounting rod.

[0021] In one embodiment, the side of the first push switch away from the mounting rod is the first pressure-receiving side, and the lower side of the first push switch is the first guide side. The first guide side extends obliquely downward from the lower edge of the first pressure-receiving side toward the mounting rod. When the first push switch is reset, the lower end of the first guide side is flush with the outer periphery of the mounting rod or located inside the mounting rod.

[0022] With this configuration, as the pressing member slides upward to press the first pressing switch, the first guide side can guide the pressing member to the first pressure-receiving side, which is conducive to the pressing member pressing the first pressing switch smoothly.

[0023] In one embodiment, the side of the second push switch away from the mounting rod is the second pressure side, and the upper side of the second push switch is the second guide side. The second guide side extends obliquely upward from the upper edge of the second pressure side toward the mounting rod. When the second push switch is reset, the upper end of the second guide side is flush with the outer periphery of the mounting rod or located inside the mounting rod.

[0024] With this configuration, as the pressing member slides downward to press the second pressing switch, the second guide side can guide the pressing member to the second pressure side, which is conducive to the pressing member pressing the second pressing switch smoothly.

[0025] In one embodiment, the oven further includes a first limiting member, which is fixedly connected to the upper part of the mounting rod and protrudes from the mounting rod in a direction perpendicular to the length of the mounting rod; the pressing member is located below the first limiting member.

[0026] This design prevents the pressing component from detaching from the mounting rod during upward sliding.

[0027] In one embodiment, the oven further includes a second limiting member, which is fixedly connected to the lower part of the mounting rod and protrudes from the mounting rod in a direction perpendicular to the length of the mounting rod; the pressing member is located above the second limiting member.

[0028] This design prevents the pressing component from detaching from the mounting rod during downward sliding.

[0029] In one embodiment, the food carrier and the pressing member are integrally formed.

[0030] This design eliminates the need for assembly between the food carrier and the pressing component, making it convenient for users.

[0031] In one embodiment, the upper heating tube and the lower heating tube are positioned opposite each other.

[0032] With this design, the pressing component only needs to move a short distance to bring the food carrier closer to the upper and lower heating elements, which helps to reduce the stroke required by the pressing component. Attached Figure Description

[0048] See Figures 1 to 3 This application provides an oven, which includes an inner cavity 1, an upper heating element 2, a lower heating element 3, and a food carrier 8. The inner cavity 1 has a top wall 11 and a bottom wall 12. The upper heating element 2 is disposed near the top wall 11, and the lower heating element 3 is disposed near the bottom wall 12. The food carrier 8 is located inside the inner cavity 1 and between the upper heating element 2 and the lower heating element 3. Food is placed on the food carrier 8 for baking.

[0049] See Figures 1 to 7The oven also includes a mounting rod 4, a first press switch 5, a second press switch 6, and a pressing element 7. The mounting rod 4 is fixed to the inner liner 1, and the angle between the length direction of the mounting rod 4 and the vertical direction is less than 45° (i.e., the mounting rod 4 is vertically positioned, or the mounting rod 4 is inclined relative to the plumb line but the inclination angle is less than 45°). Both the first press switch 5 and the second press switch 6 are located on the mounting rod 4, with the first press switch 5 positioned above the second press switch 6. The distance between the first press switch 5 and the second press switch 6 along the length direction of the mounting rod 4 is D. One of the first press switch 5 and the second press switch 6 is electrically connected to the upper heating element 2, and the other is electrically connected to the lower heating element 3. When the first press switch 5 is pressed and the second press switch 6 is reset, the upper heating element 2 is activated and the lower heating element 3 is deactivated. When the first press switch 5 is reset and the second press switch 6 is pressed, the upper heating element 2 is deactivated and the lower heating element 3 is activated. The pressing element 7 is slidably connected to the mounting rod 4. The first pressing switch 5 and the second pressing switch 6 are both located on the sliding path of the pressing element 7 so that they can be pressed by the pressing element 7. The dimension of the pressing element 7 along the length direction of the mounting rod 4 is L, and L and D satisfy: L < D. The food carrier 8 is fixedly connected to the pressing element 7.

[0050] This oven has at least the following beneficial effects:

[0051] Because L < D, the pressing member 7 cannot simultaneously press the first pressing switch 5 and the second pressing switch 6. In other words, the pressing member 7 can only press one of the first pressing switch 5 and the second pressing switch 6 at a time. When the pressing member 7 slides upward to the first pressing switch 5, the first pressing switch 5 is pressed, and the second pressing switch 6 has been reset. The upper heating element 2 is activated, and the lower heating element 3 is deactivated. At this time, the food carrier 8 moves closer to the upper heating element 2 as the pressing member 7 moves upward. When the pressing member 7 slides downward to the second pressing switch 6, the second pressing switch 6 is pressed, and the first pressing switch 5 has been reset. The upper heating element 2 is deactivated, and the lower heating element 3 is activated. At this time, the food carrier 8 moves closer to the lower heating element 3 as the pressing member 7 moves downward. During the baking process in this oven, when it is necessary to improve the baking effect of the upper part of the food, the pressing part 7 can be slid to the first pressing switch 5, so that the food carrier 8 is close to the upper heating tube 2, the upper heating tube 2 is turned on and the lower heating tube 3 is turned off, thereby baking the upper part of the food; when it is necessary to improve the baking effect of the lower part of the food, the pressing part 7 can be slid to the second pressing switch 6, so that the food carrier 8 is close to the lower heating tube 3, the upper heating tube 2 is turned off and the lower heating tube 3 is turned on, thereby baking the lower part of the food. Repeating the above process can make the baking effect of the upper and lower parts of the food consistent, can make the food evenly browned, and can improve the taste of the food.

[0052] In some embodiments, both the first push switch 5 and the second push switch 6 are normally open buttons. The first push switch 5 is connected in series with the upper heating element 2, and the second push switch 6 is connected in series with the lower heating element 3. Thus, when the pressing member 7 slides upward to the first push switch 5, the first push switch 5 is pressed and closed, energizing the upper heating element 2, and the second push switch 6 is reset and open, turning off the lower heating element 3. When the pressing member 7 slides downward to the second push switch 6, the second push switch 6 is pressed and closed, energizing the lower heating element 3, and the first push switch 5 is reset and open, turning off the upper heating element 2. In these embodiments, the oven can be connected to external AC power to supply power to the upper heating element 2 and the lower heating element 3. The external AC power, the upper heating element 2, and the first push switch 5 are connected in series to form a closed loop, and the external AC power, the lower heating element 3, and the second push switch 6 are connected in series to form another closed loop.

[0053] In other embodiments, both the first push switch 5 and the second push switch 6 are normally closed buttons. The first push switch 5 is connected in series with the lower heating element 3, and the second push switch 6 is connected in series with the upper heating element 2. Thus, when the pressing member 7 slides upward to the first push switch 5, the first push switch 5 is pressed and is in the open state, the lower heating element 3 is turned off, and the second push switch 6 has reset and is in the closed state, energizing the upper heating element 2. When the pressing member 7 slides downward to the second push switch 6, the second push switch 6 is pressed and is in the open state, the upper heating element 2 is turned off, and the first push switch 5 has reset and is in the closed state, energizing the lower heating element 3. In these embodiments, the oven can be connected to external AC power to supply power to the upper heating element 2 and the lower heating element 3. The external AC power, the upper heating element 2, and the second push switch 6 are connected in series to form a closed loop, and the external AC power, the lower heating element 3, and the first push switch 5 are connected in series to form another closed loop.

[0054] Preferably, see Figure 4 and Figure 6 The pressing element 7 is fitted onto the mounting rod 4 and conforms to the shape of the mounting rod 4. This helps to ensure that the pressing element 7 slides along the length of the mounting rod 4.

[0055] exist Figure 4 and Figure 6 In the illustrated embodiment, the mounting rod 4 is cylindrical, and the pressing member 7 is annular. In other embodiments, the mounting rod 4 may be cuboid, and correspondingly, the pressing member 7 may be square annular.

[0056] See Figure 6 and Figure 7The side of the first push switch 5 furthest from the mounting rod 4 is the first pressure-receiving side 51, and the lower side of the first push switch 5 is the first guide side 52. The first guide side 52 extends obliquely downward from the lower edge of the first pressure-receiving side 51 toward the mounting rod 4. In the reset state of the first push switch 5, the lower end of the first guide side 52 is flush with the outer periphery of the mounting rod 4 or located inside the mounting rod 4. In this way, during the process of the pressing member 7 sliding upward to press the first push switch 5, the first guide side 52 can guide the pressing member 7 to the first pressure-receiving side 51, which is conducive to the pressing member 7 pressing the first push switch 5 smoothly.

[0057] See Figure 6 and Figure 7 The side of the second push switch 6 furthest from the mounting rod 4 is the second pressure-receiving side 61, and the upper side of the second push switch 6 is the second guide side 62. The second guide side 62 extends obliquely upward from the upper edge of the second pressure-receiving side 61 toward the mounting rod 4. In the reset state of the second push switch 6, the upper end of the second guide side 62 is flush with the outer periphery of the mounting rod 4 or located inside the mounting rod 4. In this way, during the process of the pressing member 7 sliding downward to press the second push switch 6, the second guide side 62 can guide the pressing member 7 to the second pressure-receiving side 61, which is conducive to the pressing member 7 pressing the second push switch 6 smoothly.

[0058] In some embodiments, a slope that can function as a first guide side 52 and / or a second guide side 62 may also be provided on the pressing member 7.

[0059] See Figures 4 to 6 The oven also includes a first limiting member 9, which is fixedly connected to the upper part of the mounting rod 4 and protrudes from the mounting rod 4 in a direction perpendicular to the length of the mounting rod 4; the pressing member 7 is located below the first limiting member 9. This prevents the pressing member 7 from detaching from the mounting rod 4 during upward sliding.

[0060] See Figure 1 and Figure 2 A connecting rod 10 is fixedly installed inside the inner liner 1, and a first limiting member 9 is sleeved on the connecting rod 10 and fixed together with it. In other words, the mounting rod 4 is fixedly connected to the inner liner 1 through the first limiting member 9 and the connecting rod 10.

[0061] In some embodiments, the oven further includes a second limiting member, which is fixedly connected to the lower part of the mounting rod 4 and protrudes from the mounting rod 4 in a direction perpendicular to the length of the mounting rod 4; the pressing member 7 is located above the second limiting member. This prevents the pressing member 7 from disengaging from the mounting rod 4 during downward sliding.

[0062] Preferably, the second limiting member is detachably connected to the mounting rod 4 so that the pressing member 7 can be fitted onto the mounting rod 4 during the oven assembly process.

[0063] In some embodiments, the food carrier 8 and the pressing member 7 are integrally formed. This eliminates the need for assembly between the food carrier 8 and the pressing member 7, making it convenient for the user.

[0064] In other embodiments, the food carrier 8 is welded to / clamped to / screwed to the pressing member 7.

[0065] In some embodiments, the upper heating element 2 and the lower heating element 3 are arranged facing each other. In this way, the pressing element 7 only needs to move a short distance to bring the food carrier 8 close to the upper heating element 2 and the lower heating element 3, which helps to reduce the stroke required by the pressing element 7.

[0066] In other embodiments, the upper heating tube 2 and the lower heating tube 3 may also be at least partially offset.

[0067] exist Figure 2 In the illustrated embodiment, the food carrier 8 is a gripper that holds the food, suspending it within the inner liner 1 for baking. Specifically, see [reference needed]. Figure 2 The food carrier 8 includes a connecting part 81 and a claw part 82. The connecting part 81 is fixedly connected to the pressing part 7, and the claw part 82 is disposed on the connecting part 81.

[0068] In other embodiments, the food carrier 8 may also be a baking pan / grill / roasting fork.

[0069] In some embodiments, the oven includes a drive assembly and a control module. The drive assembly drives the pressing member 7 to slide, and the control module is electrically connected to the drive assembly to control the action of the drive assembly, thereby controlling the sliding of the pressing member 7.

[0070] In other embodiments, the pressing member 7 is manually controlled by the user, a portion of which extends outside the entire oven to form a lifting rod, and the oven door is at least partially transparent to allow the user to observe the state of the food. In these embodiments, the user can observe the state of the food through the door and can manually control the lifting rod along the length of the mounting rod 4 while wearing oven mitts, thereby causing the pressing member 7 to slide relative to the mounting rod 4.

[0071] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0072] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of protection of this application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the appended claims.
