Description

Technical Field

[0001] This utility model relates to the field of kitchen equipment technology, and in particular to a lifting mechanism and a toaster. Background Technology

[0002] Currently, an existing toaster for baking sliced ​​bread includes an outer shell, a bracket, and a handle assembly. The outer shell contains a baking chamber, and the bracket is movably installed within the baking chamber, with one end extending out of the chamber and directly connected to the handle assembly. The handle assembly has a first engaging portion and a spring. This spring acts between the outer shell and the handle assembly to provide an upward restoring force. The outer shell has a latching mechanism below the handle assembly, comprising a fixed base and a movable block. The fixed base has a built-in electromagnet, and the block has a magnetic element and a second engaging portion. The block is mounted on the base and can be rotated relative to the base.

[0003] During operation, the user places the bread slices on the tray inside the baking chamber and manually presses down the handle assembly to engage the first and second locking parts. At the same time, the handle assembly triggers the power switch of the electromagnet, causing the electromagnet to generate magnetic force and attract the magnetic element of the block, thus fixing the block to the base and ensuring that the first and second locking parts remain locked. When the baking program ends, the control circuit cuts off the power to the electromagnet, the magnetic attraction of the electromagnet disappears, the moving block loses its magnetic constraint, causing the second locking part to release its constraint on the first locking part. The spring pushes the handle assembly upward, causing the tray to rise and push the bread slices out of the baking chamber.

[0004] However, this design has a significant drawback: after baking, the tray's upward travel is limited, resulting in only a small portion of the bread being exposed. During the process of taking it out, the user's fingers are likely to come into contact with the hot area around the opening of the baking chamber, posing a risk of burns. To solve this problem, the extension height of the tray needs to be increased. However, since the tray and handle assembly are directly linked, increasing the tray's lifting distance inevitably requires the handle assembly to have a greater operating stroke, which will increase the user's operating burden and affect the user experience. Therefore, it is necessary to develop a new type of toaster that can push the bread further out of the baking chamber while maintaining the original operating stroke of the handle assembly, making it easier to take out and avoiding burns.

Detailed Implementation

[0021] Below, in conjunction with Figures 1 to 8 The present invention will be further described in the figures and in preferred embodiments and other embodiments. It should be noted that, without conflict, the various technical features described below can be arbitrarily combined to form new embodiments.

[0022] refer to Figure 1 , Figure 2 and Figure 5In a preferred embodiment, this utility model provides a toaster, including a baking cavity 20, a bracket 5, a handle 13, and a lifting mechanism 10. The lifting mechanism 10 includes: a fixed support 1, a first slider 2, a first drive mechanism 6, a second slider 3, and a second drive mechanism 4. The fixed support 1 has a slide rod 11 along the vertical direction. The first slider 2 is slidably connected to the slide rod 11. The first drive mechanism 6 provides an upward driving force to the first slider 2. The second slider 3 is movably connected to the first slider 2. The second drive mechanism 4 is fixed relative to the first slider 2 and can drive the second slider 3 to move upward relative to the first slider 2. The bracket 5 is movably disposed within the baking cavity 20. The lifting mechanism 10 is disposed outside the baking cavity 20. The fixed support 1 is fixed relative to the baking cavity 20. One end of the bracket 5 extends out of the baking cavity 20 and is connected to the second slider 3. The handle 13 is disposed on the first slider 2. The second drive mechanism 4 drives the second slider 3 to move upward relative to the first slider 2, so that the upward stroke of the second slider 3 is greater than that of the first slider 2. Figure 3 , Figure 4 and Figure 6 As shown, in this embodiment, the first slider 2 protrudes upward from the second slider 3 so that the second slider 3 does not increase the design space of the lifting mechanism 10 in the height direction. In this embodiment, the first slider 2 is provided with a sliding groove 21 in the vertical direction, and the second slider 3 slides between the top wall and the bottom wall of the sliding groove 21. Specifically, the second slider 3 is located on one side of the first slider 2, the top end of the second slider 3 protrudes towards the first slider 2 with a first protrusion 31, and the bottom end of the second slider 3 protrudes towards the first slider 2 with a second protrusion 32. The first protrusion 31 and the second protrusion 32 are located in the sliding groove 21, and the slide rod 11 passes through the sliding groove 21, the first protrusion 31 and the second protrusion 32 in the vertical direction. The first protrusion 31 and the second protrusion 32 can slide along the slide rod between the top wall and the bottom wall of the sliding groove 21.

[0023] like Figure 3 , Figure 4 and Figure 6As shown, in a preferred embodiment, the first slider 2 has a first position and a second position relative to the fixed bracket 1. The first slider 2 can slide along the slide bar 11 between the first position and the second position. The second driving mechanism 4 includes a second elastic element 41 and a lever 42. The second elastic element 41 is connected between the first slider 2 and the second slider 3, and provides an upward driving force to the second slider 3. The lever 42 includes a fixed part 421, a first arm 422 protruding from the fixed part 421 in a direction away from the fixed part 421, and a second arm 423 protruding from the fixed part 421 in a direction away from the first arm 422. The fixed part 421 is rotatably connected to the first slider 2. The fixed bracket 1 is provided with a top rod 12 and is located below the first arm 422. When the first slider 2 is in the first position, the second arm 423 is separated from the second slider 3. When the first slider 2 is in the second position, the top rod 12 abuts against the first arm 422 upward, and the second arm 423 abuts against the second slider 3 downward. When operating the toaster, driving the handle 13 downwards overcomes the upward force of the first elastic element 61, driving the first slider 2 and the second slider 3 from the first position downwards to the second position. The toaster's holding mechanism holds the first slider 2 in the second position. Simultaneously, the top rod 12 abuts upwards against the first arm 422, driving the second arm 423 to rotate downwards to abut against the second slider 3. The second arm 423 drives the second slider 3 downwards, overcoming the upward force of the second elastic element 41, thereby moving the tray 5 to move the bread placed on the tray 5 downwards to the preset position in the baking cavity 20. When the toaster completes the bread baking, the toaster's holding mechanism... The holding mechanism releases the restraint on the first slider 2, and the first elastic element 61 drives the first slider 2 and the second slider 3 to move together from the second position toward the first position. At the same time, the restraint on the first arm 422 is removed, thereby releasing the downward force of the second arm 423 on the second slider 3. As a result, the second slider 3 moves upward relative to the first slider 2 under the action of the second elastic element 41, so that the bracket 5 rises higher relative to the handle 13, so that the toasted bread is pushed further away from the baking cavity 20, making it easier for the user to pick up, avoiding burns to the user, and making it easier to meet the requirements of safety certification, namely, the position of the toasted bread slice remaining in the toaster is less than 60mm, and the bread slice extends more than 20mm out of the toaster opening, making it easier for consumers to pick up the bread slice.

[0024] like Figure 6 As shown, in a preferred embodiment, the upper end of the second elastic member 41 is fixed to the first slider 2, and the lower end of the second elastic member 41 pulls the second slider 3 upward. In this embodiment, the second elastic member 41 is a spring.

[0025] like Figure 2 and Figure 5 As shown, in a preferred embodiment, the first slider 2 has a width direction X and a length direction Y arranged horizontally, the length direction Y being perpendicular to the width direction X. The thickness of the first slider 2 along the length direction Y is greater than the thickness of the first slider 2 along the width direction X. The second slider 3 is disposed on one side of the first slider 2 along the width direction X. Two slide rods 11 are provided and arranged along the length direction Y of the first slider 2. The first slider 2 has a sliding groove 21 corresponding to each slide rod 11. The first slider 2 has a receiving groove 22, which is located between the two sliding grooves 21. The first driving member includes a first elastic member 61. The upper end of the first elastic member 61 is fixed to the fixed bracket 1, and the lower end of the first elastic member 61 pulls the first slider 2 upward. The first elastic member 61 is disposed in the receiving groove 22. In this embodiment, the first elastic member 61 is a spring.

[0026] like Figure 2 , Figure 4 and Figure 6 As shown, in a preferred embodiment, the second slider 3 has a stop 33 protruding towards the lever 42. When the first slider 2 is in the first position, the second arm 423 is directly above the stop 33, and the first arm 422 is below the stop 33 and offset from the stop 33 in the vertical direction. When the first slider 2 is in the second position, the first arm 422 is above the stop 33, and the second arm 423 abuts against the stop 33 downwards. In this embodiment, the stop 33 is the second protrusion 32.

[0027] like Figure 2 , Figure 4 and Figure 6 As shown, in a preferred embodiment, the first slider 2 is provided with a limiting protrusion 23, which is located below the first arm 422. The first arm 422 can abut against the limiting protrusion 23 downward. The limiting protrusion 23 is offset from the top rod 12 in the vertical direction. By providing the limiting protrusion 23, the first arm 422 is prevented from rotating excessively under the action of gravity.

[0028] like Figure 1 As shown, in a preferred embodiment, the toaster of this invention further includes a circuit control module 30, and the baking cavity 20 and the circuit control module 30 are respectively located on opposite sides of the lifting mechanism 10.

[0029] like Figure 8The illustration shows another embodiment, which differs from the preferred embodiment in that the second elastic member 41 is arranged differently. Specifically, in this embodiment, the slide rod 11 passes through the second elastic member 41, and the second elastic member 41 abuts against the first slider 2 and the second slider 3. In a specific embodiment, the second elastic member 41 abuts against the second protrusion 32 and the bottom wall of the sliding groove 21. In this embodiment, the first arm 422 has a through groove 4221, and the second slider 3 has a pin 34. The pin 34 is inserted into the through groove 4221 and can move within the through groove 4221 to prevent the first arm 422 from rotating excessively under the action of gravity. In this embodiment, the second elastic member 41 is a spring.

[0030] The beneficial effect of the lifting mechanism of this utility model is that the second slider is driven to move upward relative to the first slider by the second driving mechanism, so that the upward stroke of the second slider is higher than that of the first slider, so that the baked bread is pushed further away from the baking cavity, making it easier for the user to pick up and avoiding burns to the user.

[0031] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not be construed as limiting the scope of the present invention. All equivalent changes and modifications made in accordance with the scope of this application should still fall within the scope of the present invention.
