Automatic toaster

Abstract

This invention discloses an automatic toaster, which includes a base, heating components, and a housing. The heating components include a front heating element and a rear heating element. It also includes a bread rack assembly, a lifting mechanism, a horizontal moving mechanism, a support, and a controller. Compared to existing technologies, by configuring the heating components of the toaster to be driven by the horizontal moving mechanism and having their spacing adjusted by a bread clamping sensor module, the distance between the left and right heating components is automatically adjusted according to the bread thickness to accommodate breads of different thicknesses. This ensures that both sides of the bread are evenly toasted. The lifting mechanism pushes out the toasted bread, preventing issues such as the bread bouncing or failing to rise due to varying weights.

Description

Technical Field

[0001] This invention relates to a household appliance, and more particularly to an automatic toaster. Background Technology

[0002] Currently available toasters on the market typically have a fixed bread tray width of 30-38mm. This fixed width means they can only bake bread of one thickness. If the bread is thinner than the tray width, it will bake unevenly because the tray is too wide. Conversely, if the bread is thicker than the tray width, the tray may not be wide enough to accommodate it. Later, toasters with adjustable bread tray widths appeared on the market. However, these require manual adjustment and cannot automatically adjust the tray width based on bread thickness. Furthermore, the bread rack still uses tension springs or springs to lift the bread, which is sensitive to the weight of the bread. This can cause lighter bread to bounce off while heavier bread cannot be lifted, causing inconvenience for the user. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic toaster, and the technical problem to be solved is to meet the needs of bread of different thicknesses, ensure that both sides of the bread are baked evenly, and at the same time prevent the bread from being pushed out smoothly after baking.

[0005] Toasters also include:

[0006] A bread tray assembly is positioned between the front heating element and the rear heating element;

[0007] The lifting mechanism is located at one end of the left and right sides of the heating component. The lifting mechanism is connected to the bread tray assembly to drive the bread tray assembly to move vertically up and down.

[0008] A horizontal moving mechanism is connected to the rear heating component to drive the rear heating component to move horizontally, thereby making the distance between the front heating component and the rear heating component adjustable.

[0010] The controller is connected to the lifting mechanism, the horizontal moving mechanism, and the heating component respectively, and controls their operation or cessation.

[0011] Furthermore, the front heating assembly includes a front heating plate and a front partition mesh disposed on the side of the front heating plate opposite to the rear heating assembly.

[0012] Furthermore, the rear heating plate is capable of generating heat, a left partition and a right partition are respectively arranged on the left and right sides of the rear heating plate, and a rear partition mesh is arranged on the side of the rear heating plate opposite to the front heating component. The left and right ends of the rear partition mesh are movably connected to the left partition and the right partition, respectively.

[0013] Furthermore, the horizontal moving mechanism is located on the side of the rear panel away from the rear heating component. The horizontal moving mechanism includes a rear drive motor, a rear motor bracket, a push arm, and a motor push rod. The rear drive motor is fixed to the base via the rear motor bracket and is connected to the controller. The output shaft of the rear drive motor is horizontally positioned. One end of the push arm is connected to the output shaft of the rear drive motor, and the other end of the push arm has a push arm groove along the length of the push arm. The motor push rod is fixed to the end face on the side away from the front heating component via a connecting rod bracket. The axis of the motor push rod is parallel to the output shaft of the rear drive motor. One end of the motor push rod passes through the push arm groove to drive the push arm when the rear drive motor rotates clockwise or counterclockwise, thereby pushing the rear heating component to move horizontally towards or away from the front heating component.

[0014] Furthermore, the horizontal movement mechanism also includes a micro switch, which is located below the push arm and fixed on the rear motor bracket. The micro switch is connected to the controller, and the free end of the drive spring of the micro switch is located below the push arm. The push arm is provided with a pressing part so that when the rear drive motor drives the push arm to rotate and drives the rear heating component to move horizontally away from the front heating component, the pressing part presses the drive spring. After the micro switch sends an electrical signal to the controller, the controller controls the rear drive motor to stop rotating.

[0015] Furthermore, the horizontal moving mechanism also includes a rotating link, which includes an inverted U-shaped part, a first bent part on the two feet of the U-shaped part, and a second bent part on the first bent part.

The rear drive motor is fixed on the rear motor bracket. The axis of the output shaft of the rear drive motor is perpendicular to the surface of the left or right side plate. The lower end of the push arm is fixed on the output shaft of the rear drive motor. The rear drive motor is connected to the controller. The upper end of the push arm is provided with a push arm groove. A motor push rod extending into the push arm groove is provided on the left or right partition adjacent to the push arm. An electric push rod sliding hole is provided on the left or right side plate through which the motor push rod passes. The electric push rod sliding hole is arranged along the moving trajectory direction of the rear heating component so that when the rear drive motor drives the push arm to rotate, it drives the motor push rod to move together, pushing the rear heating component to move horizontally towards or away from the front heating component.

[0017] Furthermore, the horizontal movement mechanism also includes a micro switch, which is mounted on the rear motor bracket and located at one end of the rotation trajectory of the push arm. The micro switch is connected to the controller, and the push arm is provided with a pressing part that can press the drive spring of the micro switch. When the rear drive motor drives the push arm to rotate and drives the rear heating component to move horizontally away from the front heating component, the pressing part presses the drive spring. After the micro switch sends an electrical signal to the controller, the controller controls the rear drive motor to stop rotating.

[0018] Furthermore, the horizontal moving mechanism also includes at least one set of push rods symmetrically arranged on the left and right partitions.

The upper ends of the push rod arms are respectively hinged to the left partition and the right partition, and the lower ends of the two push rod arms are respectively hinged to the lower ends of the left side plate and the right side plate. The hinge positions of the two push rod arms with the left partition and the right partition are on the same straight line as the hinge positions of the left push rod and the right push rod with the left partition and the right partition. The hinge positions of the two push rod arms with the left side plate and the right side plate are on the same straight line as the hinge positions of the left push rod and the right push rod with the left side plate and the right side plate.

[0020] Furthermore, the rear heating element is equipped with a bread clamping sensing module that can move together with the rear heating element. The bread clamping sensing module is located outside the bracket and includes at least one set of reset components and sensing components. The reset components are connected to the left or right partition plate via a connecting piece. The left or right partition plate is provided with a first clearance groove that avoids the connecting piece. The connecting piece passes through the first clearance groove, and the sensing components are located in the stroke of the reset components. The rear partition includes at least an upper crossbar and a lower crossbar. The two ends of the upper crossbar pass through the left waist-shaped hole on the left partition plate and the right waist-shaped hole on the right partition plate, respectively. The upper crossbar is connected to the reset components. One end of the component passes through the left or right side plate and extends into the reset assembly. The end of the upper crossbar opposite to the sensing assembly passes through the reset assembly on that side and extends to be opposite to the sensing assembly, forming a contact part. The two ends of the lower crossbar are respectively hinged to the lower ends of the left and right partitions. The left and right side plates are respectively provided with second clearance grooves to avoid the upper crossbar. The first and second clearance grooves at least cover the horizontal movement stroke of the rear heating assembly. The sensing assembly is connected to the controller. After the contact part contacts the sensing assembly, the controller detects the electrical signal of the sensing assembly and controls the rear drive motor to stop rotating.

[0021] Furthermore, the reset assembly includes a mesh spring and a spring bracket. The spring bracket is fixed to the left or right partition plate by a connecting piece. The spring bracket is provided with a spring groove, the opening of which faces the front heating assembly. The axial direction of the mesh spring is parallel to the moving direction of the rear heating assembly and is fixed in the spring groove. The part of the upper crossbar that extends out of the left or right side plate extends into the spring groove and abuts against the mesh spring.

[0022] Furthermore, the reset assembly is provided in two sets, which are respectively connected to the left partition and the right partition via connecting pieces.

[0023] Furthermore, the sensing component is a capacitive sensing plate, which is connected to a connecting piece on one side via a capacitive sensing plate bracket, with the sensing surface of the capacitive sensing plate facing the contact portion.

[0024] Furthermore, the lifting mechanism is located on the side of the left or right side plate away from the heating component. The lifting mechanism includes a motor bracket, a drive motor, a lifting rocker arm, a slide, and a guide assembly. The motor bracket is fixed on the base, and the drive motor is fixed on the motor bracket with its output shaft perpendicular to the surface of the left or right side plate. One end of the lifting rocker arm is connected to the output shaft of the drive motor, and the other end is provided with a pulley. The slide is located on the side opposite to the pulley and has a sliding groove horizontally positioned on it. The pulley is positioned in the sliding groove. The guide assembly is fixed on the base, and the sliding end of the guide assembly is connected to the slide and the bread tray assembly respectively. When the drive motor rotates, it drives the lifting rocker arm to rotate and pushes the sliding end of the slide and the guide assembly to move vertically, thereby driving the bread tray assembly to move vertically. Vertically positioned bread tray guide slots are provided on the left and right side plates. One end of the bread tray assembly passes through the bread tray guide slot on the left or right side plate and connects to the sliding end of the guide assembly, while the other end passes through the bread tray guide slot on the right or left side plate.

[0025] Furthermore, the guide assembly includes at least one vertical shaft and a sliding plate that can slide back and forth on the vertical shaft. The sliding plate constitutes a sliding end. One end of the bread tray assembly is connected to the sliding plate, and the sliding plate is also connected and fixed to the carriage.

[0026] Furthermore, the lifting mechanism also includes a set of limit switches connected to the controller. The limit switches include an upper limit switch and a lower limit switch set on the rotation trajectory of the lifting rocker arm. The upper limit switch and the lower limit switch are arranged left and right and opposite to each other. The lifting rocker arm is provided with a contact for triggering the upper limit switch or the lower limit switch. When the lifting rocker arm rotates and drives the slide to rise to the highest point, the contact contacts the upper limit switch. When the lifting rocker arm rotates and drives the slide to fall to the lowest point, the contact contacts the lower limit switch.

[0027] Furthermore, the bread tray assembly includes two opposing channel steels and a plurality of hinges disposed between the two channel steels. Each hinge has two blades, which are respectively hinged to the two channel steels to allow the bread tray assembly to be folded horizontally. One channel steel passes through the bread tray guide slots on the left and right side panels, and one end of the channel steel is connected to the lifting mechanism. The other channel steel is connected to the rear heating component via a retaining ring. When the rear heating component moves horizontally, it drives the channel steel to move, causing the panel tray assembly to fold or unfold horizontally.

[0028] Furthermore, the present invention also includes a bread clip that can be placed between the front heating component and the rear heating component. The bread clip includes two identical clip bodies, the lower ends of the two clip bodies are hinged together, and a handle is provided on one side of the upper end of the clip bodies.

[0029] Compared with the prior art, this invention sets the heating elements of the toaster to be driven by a horizontal movement mechanism and the spacing of the elements can be adjusted by a bread clamping sensor module. This allows for automatic adjustment of the spacing between the left and right heating elements according to the thickness of the bread, thus meeting the baking needs of breads of different thicknesses. At the same time, it ensures that both sides of the bread are baked evenly. The lifting mechanism pushes out the baked bread, preventing problems such as the bread bouncing or failing to rise due to different weights. Attached Figure Description

[0050] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0051] like Figure 1 , Figure 2 , Figure 3 Figure 5 and Figure 11 As shown, the present invention discloses an automatic toaster comprising:

[0052] Base 1;

[0053] The heating components mounted on the base 1 include a front heating component 2 and a rear heating component 3, with the heating surfaces of the front heating component 2 and the rear heating component 3 facing each other, and the front heating component 2 being fixed to the base 1.

[0054] The outer shell 4 has an opening for putting bread in, and the outer shell 4 is connected and fixed to the base 1 by screws;

[0055] The bread tray assembly 5 is positioned between the front heating assembly 2 and the rear heating assembly 3;

[0056] The lifting mechanism 6 is located on one of the left and right sides of the heating component. The lifting mechanism 6 is connected to the bread tray assembly 5 to drive the bread tray assembly 5 to move vertically up and down.

[0057] The horizontal moving mechanism 7 is connected to the rear heating component 3 to drive the rear heating component 3 to move horizontally, so that the distance between the front heating component 2 and the rear heating component 3 can be adjusted.

[0058] The bracket includes a left side plate 8, a right side plate 9, and a rear side plate 10. The left side plate 8 and the right side plate 9 are respectively connected and fixed to the rear side plate 10 and the base 1. The rear side plate 10 is located on the side of the rear heating element 3 facing away from the front heating element 2. The left side plate 8, the right side plate 9, the rear side plate 10, and the base 1 can be fixed by screws or by setting holes and bendable inserts. The holes and bendable inserts are set by inserting the inserts into the corresponding holes and bending the inserts so that the inserts cannot come out of the holes. The front heating element 2 is located on the side opposite to the rear side plate 10. The front heating element 2, the left side plate 8, the right side plate 9, and the rear side plate 10 form a space for the rear heating element 3 to move horizontally. The front heating element 2 is fixed to the left side plate 8 and the right side plate 9. The fixing method can be achieved by using inserts and holes.

[0059] The controller 11 is connected to the lifting mechanism 6, the horizontal moving mechanism 7, and the heating component respectively, and controls their operation or shutdown. The controller 11 has a control board, function buttons, and light displays (not shown in the figure). This part is prior art. The control logic of the control board is to receive the electrical signals sent by the mechanism and control the corresponding linked mechanism to operate or stop. The function buttons are used for function selection and start or emergency stop. The light displays use different colors to distinguish between working, standby, and completed prompts.

[0060] The present invention drives the rear heating component 3 to move between the left side plate 8 and the right side plate 9 through the horizontal moving mechanism 7, so as to adjust the bread baking slot to the appropriate width of the bread to be baked.

[0061] In this invention, the bread tray assembly 5 has a foldable structure, such as... Figure 5-1 , Figure 5-2 and Figure 19 As shown, the bread tray assembly 5 consists of two channel steels 12 and several hinges 13. One end of the two blades of each hinge 13 is hinged to a hinge shaft, and the other end of each blade is hinged to one of the two channel steels 12 via hinge shafts. The hinge shafts are vertically oriented to allow the bread tray assembly 5 to fold horizontally. The folding of the bread tray assembly 5 is controlled by the rear heating component. When the rear heating component moves horizontally, it drives the opposite channel steel 12 to move towards the other channel steel 12, causing the hinges 13 to fold. A torsion spring is also provided on the hinge shaft where the two blades are hinged. The torsion spring is used to twist and deform when the hinges 13 fold. When the rear heating component returns to its original state, the torsion spring returns to its original shape and drives the hinges 13 to open to cooperate with the rear heating component's return to its original state, allowing the bread tray assembly 5 to cover the gap between the front heating component and the rear heating component. Alternatively, a method such as... Figure 19 As shown, the channel steel 12 opposite to the rear heating component 3 is connected to the rear partition 20 of the rear heating component 3 by a retaining ring 67.

[0062] like Figure 4 As shown, the front heating assembly 2 includes a front heating plate 14 and a front partition 15 disposed on the side of the front heating plate 14 opposite to the rear heating assembly 3. The front partition 15 consists of two horizontally arranged crossbars and multiple vertically arranged fences. The two ends of the two crossbars pass through the mounting holes on the left side plate 8 and the right side plate 9 respectively, so that the front partition 15 is fixed to the left side plate 8 and the right side plate 9.

[0063] like Figure 7 , Figure 8 and Figure 9 As shown, the rear heating assembly 3 includes a rear heating plate 16 capable of generating heat, a left partition 17 and a right partition 18 respectively connected to the left and right sides and the top of the rear heating plate 16, a heat insulation plate 19, and a rear mesh 20 disposed on the side of the rear heating plate 16 opposite to the front heating assembly 2. The heat insulation plate 19 is formed by bending a sheet material and includes a U-shaped plate 69. The opening of the U-shaped plate 69 is disposed away from the front heating assembly 2. The U-shaped plate 69 has a top surface, a bottom surface, and a back surface. A rear back plate 70 extending vertically downward is provided on the bottom surface, and the rear back plate 70 covers... The rear heating plate 16 and the back panel 70 have a folded edge bent towards the front heating component 2 at the bottom. Slots are distributed on the bottom surface and the folded edge. The rear heating plate 16 has protruding inserts around its perimeter. These inserts are inserted into the slots on the bottom surface and the folded edge of the heat insulation plate 19, preventing the rear heating plate 16 from separating from the heat insulation plate 19. The left partition 17 and the right partition 18 are fixed to the left and right sides of the heat insulation plate 19 in the same way. The left and right sides of the rear mesh 20 are movably connected to the left partition 17 and the right partition 18, respectively. The rear mesh 20 adopts the same structure as the front mesh 15. It consists of an upper horizontal bar 21, a lower horizontal bar 22, and a fence set between the upper horizontal bar 21 and the lower horizontal bar 22. The two ends of the upper horizontal bar 21 pass through the left waist-shaped hole 23 and the right waist-shaped hole 24 reserved in the left partition 17 and the right partition 18, respectively. The two ends of the lower crossbar 22 pass through the corresponding round holes in the left partition 17 and right partition 18, respectively, so that the rear partition net 20 can rotate with the lower crossbar 22 as the center.

[0064] like Figure 3 , Figure 8 , Figure 10 and Figure 11As shown, the horizontal moving mechanism 7 is located on the side of the rear heating component 3 away from the front heating component 2. The horizontal moving mechanism 7 includes a rear motor bracket 25, a rear drive motor 26, a micro switch 27, a push arm 28, and a motor push rod 29. The rear motor bracket 25 is fixed on the base 1. The rear drive motor 26 and the micro switch 27 are fixed on the base 1 through the rear motor bracket 25 and are located on the side of the rear heating component 3 away from the front heating component 2. The rear drive motor 26 and the micro switch 27 are connected to the controller 11 to send electrical signals to the controller 11 or be controlled by the controller 11 to start and stop the rear drive motor 26. The output shaft of the rear drive motor 26 is horizontally arranged. One end of the push arm 28 is fixed on the output shaft of the rear drive motor 26. The other end of the push arm 28 is provided with a push arm groove 30 arranged along the length direction of the push arm 28. The micro switch 27 is located below the push arm 28. The push arm 28 is fixed on the rear motor bracket 25. A pressing part is provided on one end of the output shaft of the drive motor 26. When the rear drive motor 26 drives the push arm 28 to rotate and drives the rear heating component 3 to move horizontally away from the front heating component 2, the pressing part presses the drive spring 31. After the micro switch 27 sends an electrical signal to the controller 11, the controller 11 controls the rear drive motor 26 to stop rotating. The motor push rod 29 is fixed to the side end face of the rear back plate 70 away from the front heating component 2 by the connecting rod bracket 36. The axis of the motor push rod 29 is parallel to the output shaft of the rear drive motor 26. One end of the motor push rod 29 passes through the push arm groove 30 and forms a movable connection with it, so as to drive the push arm 28 when the rear drive motor 26 rotates clockwise or counterclockwise, and push the rear heating component 3 to move horizontally towards or away from the front heating component 2. The rear side plate 10 is provided with a clearance hole for the motor push rod 29 and the push arm 28 to avoid each other.

[0065] like Figure 3 , Figure 8 , Figure 10 and Figure 11 As shown, the horizontal moving mechanism 7 also includes a rotating link 32. The rotating link 32 includes an inverted U-shaped part 33, a first bent part 34 provided on the two feet of the U-shaped part 33, and a second bent part 35 provided on the first bent part 34. The link bracket 36 is provided with a horizontally arranged through groove. The horizontal part on the U-shaped part 33 is provided in the through groove and can rotate in the through groove. The first bent part 34 extends in the direction of the front heating component 2 and is located below the rear heating component 3. The second bent part 35 is provided at the end of the first bent part 34 away from the U-shaped part 33, and extends in a straight line in the direction of the left side plate 8 and the right side plate 9 respectively and passes through the through holes at the corresponding positions of the left side plate 8 and the right side plate 9, so that the rotating link 32 can rotate through the second bent part 35.

[0066] like Figure 3 , Figure 7 , Figure 8 , Figure 10 , Figure 11 , Figure 17 and Figure 18 As shown, the horizontal moving mechanism 7 also includes at least one set of push rods symmetrically arranged on the left partition 17 and the right partition 18. The push rod sets include a left push rod 37 and a right push rod 38. The upper ends of the left push rod 37 and the right push rod 38 are respectively hinged to the left partition 17 and the right partition 18, and the lower ends of the left push rod 37 and the right push rod 38 are respectively hinged to the lower ends of the left side plate 8 and the right side plate 9, so as to ensure the stability of the horizontal movement of the rear heating component.

[0067] like Figure 3 , Figure 8 , Figure 10 and Figure 11 As shown, the horizontal moving mechanism 7 also includes a synchronous push rod 39, which is U-shaped and has two push rod arms. The upper ends of the push rod arms are hinged to the left partition 17 and the right partition 18, respectively, and the lower ends of the two push rod arms are hinged to the lower ends of the left side plate 8 and the right side plate 9, respectively. The hinge positions of the two push rod arms with the left partition 17 and the right partition 18 are on the same straight line as the hinge positions of the left push rod 37 and the right push rod 38 with the left partition 17 and the right partition 18. The hinge positions of the two push rod arms with the left side plate 8 and the right side plate 9 are on the same straight line as the hinge positions of the left push rod 37 and the right push rod 38 with the left side plate 8 and the right side plate 9, further improving the stability of the horizontal movement of the rear heating component.

[0068] like Figure 8 As shown, the connecting rod bracket 36 includes a connecting part 40 that is fixed to the back plate 70. The connecting part 40 is plate-shaped, and a through groove is provided on the connecting part 40. A protruding U-shaped support arm 41 is provided at the lower end of the connecting part 40. The U-shaped support arm 41 extends toward the horizontal moving mechanism 7, and the motor push rod 29 is provided on the U-shaped support arm 41.

[0069] like Figure 7 , Figure 12 and Figure 13As shown, the rear heating element 3 is equipped with a bread clamping sensing module 42 that can move together with the rear heating element 3. The bread clamping sensing module 42 is located outside the bracket and includes two sets of reset components and sensing components 43. The reset components are connected to the left partition 17 and the right partition 18 through connecting pieces 44. The left side plate 8 and the right side plate 9 are both provided with first clearance grooves 45 to avoid the connecting pieces 44. The connecting pieces 44 pass through the first clearance grooves 45. The sensing components 43 are located in the stroke of the reset components. In addition to passing through the left waist-shaped hole 23 on the left partition 17 and the right waist-shaped hole 24 on the right partition 18, the two ends of the upper crossbar 21 also pass through the left side plate 8 or the right side plate 9 and extend into the reset components. In this invention, the sensing components 43 are connected to the sensing plate bracket 4. 6 is fixedly connected to the reset assembly on the left. The end of the upper crossbar 21 opposite to the sensing assembly 43 passes through the reset assembly on this side and extends to the sensing assembly 43 to form a contact part 47. The two ends of the lower crossbar 22 are respectively inserted into the holes at the lower ends of the left partition 17 and the right partition 18 to form a hinge. The upper part of the rear partition 20 can move within the left waist-shaped hole 23 and the right waist-shaped hole 24 with the lower crossbar 22 as the center. The left side plate 8 and the right side plate 9 are respectively provided with second clearance grooves 48 to avoid the upper crossbar 21. The first clearance groove 45 and the second clearance groove 48 at least cover the horizontal movement stroke of the rear heating assembly 3. The sensing assembly 43 is connected to the controller 11. After the contact part 47 contacts the sensing assembly 43, the controller 11 detects the electrical signal of the sensing assembly 43 and controls the rear drive motor 26 to stop rotating.

[0070] In this invention, the sensing component 43 is a capacitive sensing plate. The controller 11 can determine whether the rear partition 20 has been pressed against the bread by whether the contact part 47 of the upper crossbar 21 is in contact with the sensing surface of the capacitive sensing plate 43, thereby causing a change in the capacitance value of the capacitive sensing plate 43. This also allows the controller to determine whether the rear heating component 3 has moved to a distance suitable for the bread thickness. Consequently, the controller controls the horizontal moving mechanism 7 to stop driving the rear heating component 3 to move. Because the bread baking slot (i.e., the distance between the front heating component and the rear heating component) of this invention uses an automatic horizontal moving mechanism, the moving distance of the rear heating component 3 can reach 100 mm or even greater. The capacitive sensing plate 43 can also be replaced by a micro switch or a tactile switch. That is, the contact part 47 of the upper crossbar 21 is pressed against the tactile switch or the micro switch to close it, thereby determining whether the rear partition 20 is being squeezed by the bread. This controls the automatic forward and backward driving mechanism to stop driving the rear heating component 3 to move, thus achieving the purpose of controlling the bread baking slot.

[0071] like Figure 7 , Figure 12 and Figure 13As shown, the reset assembly includes a mesh spring 49 and a spring bracket 50. The spring bracket 50 is fixed to the left partition 17 and the right partition 18 by a connecting piece 44. The spring bracket 50 is provided with a spring groove, the opening of which faces the front heating component 2. The axial direction of the mesh spring 49 is parallel to the moving direction of the rear heating component 3 and is fixed in the spring groove. The part of the upper crossbar 21 that extends out of the left side plate 8 or the right side plate 9 extends into the spring groove and abuts against the mesh spring 49. Only when the rear partition 20 is squeezed by external force will the mesh spring 49 be compressed, and the contact part 47 of the upper crossbar 21 will contact the capacitive sensing plate 43.

[0072] Of course, the horizontal moving mechanism 7 in this invention can also be implemented in another form, such as... Figure 14 As shown, the horizontal moving mechanism 7 is arranged adjacent to the left side plate 8 or the right side plate 9. The horizontal moving mechanism 7 includes a rear motor bracket 25, a rear drive motor 26, and a push arm 28. The rear motor bracket 25 is fixed on the base 1 and adjacent to the left side plate 8 or the right side plate 9. The rear drive motor 26 is fixed on the rear motor bracket 25. The axis of the output shaft of the rear drive motor 26 is perpendicular to the plate surface of the left side plate 8 or the right side plate 9. The lower end of the push arm 28 is fixed on the output shaft of the rear drive motor 26. The rear drive motor 26 is connected to the controller 11. The upper end of the push arm 28 is provided with a push arm groove 30. A motor push rod 29 extending into the push arm groove 30 is provided on the left partition 17 or the right partition 18 adjacent to the push arm 28. An electric push rod sliding hole through which the motor push rod 29 passes is provided on the left side plate 8 or the right side plate 9. The electric push rod sliding hole is set along the moving trajectory direction of the rear heating component so that when the rear drive motor 26 drives the push arm 28 to rotate, it drives the motor push rod 29 to move together, pushing the rear heating component 3 to move horizontally towards the front heating component 2 or away from the front heating component 2.

[0073] The micro switch 27 is mounted on the rear motor bracket 25 and located at one end of the rotation trajectory of the rear push arm 28. The micro switch 27 is connected to the controller 11. The push arm 28 is provided with a pressing part that can press the drive spring 31 of the micro switch 27. When the rear drive motor 26 drives the push arm 28 to rotate and drives the rear heating component 3 to move horizontally away from the front heating component 2, the pressing part presses the drive spring 31. After the micro switch 27 sends an electrical signal to the controller 11, the controller 11 controls the rear drive motor 26 to stop rotating.

[0074] like Figure 2 , Figure 4 , Figure 5-1 , Figure 5-2 and Figure 6As shown, the lifting mechanism 6 is located on the side of the right side plate 9 opposite to the heating component. The lifting mechanism 6 includes a motor bracket 51, a drive motor 52, a lifting rocker arm 53, a slide 54, and a guide assembly. The motor bracket 51 is fixed to the base 1, and the drive motor 52 is fixed to the motor bracket 51 with its output shaft perpendicular to the surface of the right side plate 9. One end of the lifting rocker arm 53 is connected to the output shaft of the drive motor 52, and the other end is provided with a pulley 55. The slide 54 is located on the side opposite to the pulley 55 and has a strip-shaped structure. The slide 54 is provided with a sliding groove 56, which is horizontally arranged on the slide 54. The pulley 55 is located in the sliding groove 56. The guide assembly is fixed. Fixed on the base 1, the sliding end of the guide assembly is connected to the slide 54 and the bread tray assembly 5 respectively, so that when the drive motor 52 rotates, it drives the lifting rocker arm 53 to rotate and pushes the slide 54 and the sliding end of the guide assembly to move vertically, thereby driving the bread tray assembly 5 to move vertically. The left side plate 8 and the right side plate 9 are provided with vertically arranged bread tray guide slots 66. The two ends of one of the channel steels 12 of the bread tray assembly 5 pass through the bread tray guide slots 66 on the left side plate 8 and the right side plate 9 respectively. One end of the channel steel 12 passes through the bread tray guide slot 66 and is connected to the sliding end of the guide assembly. The other channel steel 12 is connected to the fence of the rear partition 20 by a retaining ring 67. When the lifting rocker arm 53 rotates clockwise or counterclockwise, the pulley 55 provided on it slides in the slide groove 56 of the slide 54, thereby driving the slide 54 and the sliding end of the guide assembly to rise and fall vertically, so as to realize the vertical rise and fall of the bread tray assembly 5 in the bread baking slot constructed by the front heating component 2 and the rear heating component 3.

[0075] like Figure 19 As shown, at least one set of bearing seats is provided on the channel steel 12 connected to the fence of the rear partition 20. The bearing seats consist of two bearing seats 68 with shaft holes, which are spaced apart. One bearing seat 68 has a movable hole perpendicular to the shaft hole, which communicates with the shaft hole. The shaft hole of the other bearing seat 68 is a through hole. The retaining ring 67 consists of a rotating shaft passing through the through hole, a U-shaped sleeve that fits into the fence, and a hook passing through the movable hole and the shaft hole. During assembly, after the hook passes through the movable hole and the shaft hole, the U-shaped sleeve is fitted onto one of the fence sections. Then the rotating shaft passes through the through hole to realize the connection between the channel steel 12 and the rear partition 20.

[0076] like Figure 2 , Figure 4 , Figure 5-1 , Figure 5-2 and Figure 6As shown, the guide assembly includes two vertical shafts 57 and a sliding plate 58 that can slide back and forth on the vertical shafts 57. The sliding plate 58 forms a sliding end. One end of one of the channel steels 12 of the bread tray assembly 5 is connected to the sliding plate 58. The sliding plate 58 is also connected and fixed to the carriage 54. The sliding plate 58 is provided with a through hole for the vertical shafts 57 to pass through and form a sliding connection. The vertical shafts 57 pass through the through hole. The lower end of the vertical shafts 57 is fixed to the base 1, and the upper end is connected and fixed to the bent part at the upper end of the right side plate 9 to play a guiding role.

[0077] like Figure 2 , Figure 4 , Figure 5-1 , Figure 5-2 and Figure 6 As shown, the lifting mechanism 6 also includes a set of limit switches connected to the controller 11. The limit switches include an upper limit switch 59 and a lower limit switch 60 disposed on the rotation trajectory of the lifting arm 53. The upper limit switch 59 and the lower limit switch 60 are arranged approximately opposite each other. The lifting arm 53 is provided with a contact 61 for triggering either the upper limit switch 59 or the lower limit switch 60. When the lifting arm 53 rotates and causes the slide 54 to rise to its highest point, the contact 61 contacts the upper limit switch 59. When the lifting arm 53 rotates and causes the slide 54 to descend to its lowest point, the contact 61 contacts the lower limit switch 60. When the slide 54 rises to its highest position, the contact 61 of the lifting rocker arm 53 connected to the output shaft of the drive motor presses against the upper limit switch 59, closing it and causing the upper limit switch 59 to send an electrical signal to the controller 11. When the controller 11 receives the electrical signal, it controls the drive motor 52 to stop rotating. When the slide 54 descends to its lowest position, the contact 61 of the lifting rocker arm 53 connected to the output shaft of the drive motor presses against the lower limit switch 60, closing it and causing the lower limit switch 60 to send an electrical signal to the controller 11. When the controller 11 receives the electrical signal, it controls the drive motor 52 to stop rotating.

[0078] like Figure 2 , Figure 3 As shown, the base 1 is also provided with a power board assembly 62 to supply power to the controller 11, various mechanisms and components.

[0079] The rear heating element can move between 100 mm and 10 mm in width, thus forming a variable-width bread baking tray with a width range of 10 to 100 mm.

[0080] like Figure 15 As shown, when the bread rack assembly 5 is lowered to the lower limit position by the controller, the bread baking tray can be used to bake bread of different thicknesses by placing bread clips into it. Other fillings can be placed in the bread and clamped before being placed in the bread baking tray for baking. Alternatively, the bread clips can be used to place the food to be baked into the bread baking tray for baking.

[0081] The bread clip 63 can be inserted between the front heating component 2 and the rear heating component 3. The bread clip 63 includes two identical clip bodies 64, the lower ends of the two clip bodies 64 are hinged together, and a handle 65 is provided on one side of the upper end of the clip body 64.

[0082] The working principle of this invention is as follows:

[0083] 1. Plug in the automatic toaster and place the bread to be toasted in the bread tray;

[0084] 2. After selecting the appropriate heating level and time using the function buttons on the toaster's exterior, press the "Start" button to begin operation;

[0085] 3. The controller 11 controls the drive motor 52 on the lifting mechanism 6 to start rotating. The lifting rocker arm 53 fixed on the output shaft of the drive motor 52 also starts rotating. The pulley 55 on the lifting rocker arm 53 slides in the groove 56 on the slide frame 54. As the lifting rocker arm 53 rotates, the pulley 55 presses down on the groove 56 on the slide frame 54, causing the slide frame 54 to move downward. The bread tray assembly 5 fixed on the slide frame 54 supports the bread and moves downward until the contact 61 of the lifting rocker arm 53 presses on the lower limit switch 60, causing the lower limit switch 60 to close and send an electrical signal to the controller 11. After receiving the electrical signal, the controller 11 controls the drive motor 52 to stop rotating. At this time, the bread tray assembly 5 on the slide frame 54 supports the bread and descends to the lower limit position of the bread baking slot.

[0086] 4. When the controller 11 receives the electrical signal that the lower limit switch 60 is closed, the controller 11 controls the rear drive motor 26 of the horizontal moving mechanism 7 to start rotating. The push arm 28 fixed on the rear drive motor 26 also starts rotating. The rotation of the push arm 28 pushes the motor push rod 29 downward, and the motor push rod 29 pushes the rear heating component 3 to move towards the front heating component 2.

[0087] 5. As the rear heating component 3 moves, the distance between the rear heating component 3 and the front heating component 2 gradually decreases, and the hinge of the bread holder component 5 is gradually folded. When the rear heating component 3 moves to the rear partition 20 and presses the bread, the rear partition 20 rotates in the opposite direction due to the pressure of the bread. At this time, the part of the upper crossbar 21 on the rear partition 20 that extends out of the left partition 17 and the left side panel 8 presses on the partition spring 49, causing the partition spring 49 to be compressed. The contact part 47 of the upper crossbar 21 is rotated to contact the capacitive sensing plate 43. At this time, the controller 11 detects that the capacitance of the capacitive sensing plate 43 has changed, that is, it is determined that the rear partition 20 has contacted the bread. At this time, the rear heating component 3 has been moved to the position of clamping the bread. At this time, the controller 11 controls the rear drive motor 26 to stop rotating.

[0088] 6. Since the rear heating component 3 has moved to the position of clamping the bread, at this time, after the controller 11 controls the rear drive motor 26 to stop rotating, it controls the front and rear heating plates on the front and rear heating components to be powered on and heated until the set baking time is reached, the controller 11 controls the front and rear heating plates of the front and rear heating components to stop heating.

[0089] 7. After the bread baking is completed, the controller 11 controls the rear drive motor 26 on the horizontal moving mechanism 7 to rotate in the opposite direction, which also drives the push arm 28 to rotate in the opposite direction. The reverse rotation of the push arm 28 pushes the rear heating component 3 to move towards the starting position. When the rear heating component 3 is moved to the starting position, the pressing part of the push arm 28 presses on the drive spring 31 of the micro switch 27, causing the micro switch 27 to close and send an electrical signal to the controller 11. After receiving the electrical signal, the controller 11 controls the rear drive motor 26 to stop rotating. At this time, the rear heating component 3 has moved to the starting position. At this time, the hinge of the hinge bracket assembly 203-1 is also gradually pulled open to the width of the starting position.

[0090] 8. When the control circuit detects the electrical signal of the micro switch 27, it also controls the drive motor 52 on the lifting mechanism 6 to start rotating. The lifting rocker arm 53 fixed on the output shaft of the drive motor 52 also starts rotating. The pulley 55 on the lifting rocker arm 53 slides in the groove 56 on the slide 54. As the pulley 55 on the lifting rocker arm 53 pushes the slide 54 upward, the slide 54 moves upward. The bread tray assembly 5 fixed on the slide 54 supports the bread and moves upward until the contact 61 of the lifting rocker arm 53 presses on the upper limit switch 59, causing the upper limit switch 59 to close and send an electrical signal to the controller 11. After receiving the electrical signal, the controller 11 controls the drive motor 52 to stop rotating. At this time, the bread tray assembly 5 on the slide 54 supports the bread and rises to the upper limit position of the bread baking slot. Thus, the entire bread baking process ends.

[0091] The automatic toaster of this invention, through the inclusion of a movable rear heating element 3, a horizontal moving mechanism 7, a lifting mechanism 6, and a bread clamping sensing module 42, achieves automatic detection of bread thickness, automatic movement of the rear heating element 3 to adjust the width of the bread baking slot, and automatic sensing of bread placement followed by the slide lowering and automatic raising after baking. This ensures that breads of various sizes and weights can rise smoothly without being bounced away. More importantly, it breaks through the limitations of traditional toasters that can only bake bread of one thickness, enabling the automatic toaster to bake breads of various thicknesses within the range of 10-100mm. This expands the range and scope of food that can be baked, greatly improving the utilization rate of the toaster. Furthermore, it achieves full automation and intelligence, significantly enhancing ease of use and providing users with a unique experience. It also boasts advantages such as convenient and professional operation, safety, low operating costs, and high reliability.
