[0030] Combine the following Figures 1 to 11 , describing a detachable and cleanable toaster according to an embodiment of the present invention.

[0031] A detachable and cleanable toaster comprises a toaster body 1, a furnace 2, a bread holder and an assembly 4; a swing entrance is provided on the top of the toaster body 1, the furnace 2 can be detachably placed into the furnace body 1 through the swing entrance, and the furnace 2 is a heating chamber; heating elements 5 are provided on the side walls of the heating chamber, the bread holder can be detachably installed in the heating chamber, the assembly 4 can be detachably connected to the bread holder, and the assembly 4 is used to drive the bread holder to move up and down in the heating chamber; a power supply 3 is installed in cooperation with the bottom of the furnace 2 and the bottom of the furnace body 1.

[0032] A detachable and cleanable toaster oven can conveniently disassemble the oven shell for cleaning. A bread bracket can be detachably installed in a heating chamber, and a component 4 can be detachably connected to the bread bracket, so that the oven shell 2 can be conveniently disassembled from the interior of the oven body 1 to clean food residues and oil stains, thereby ensuring the hygienic quality of food.

[0033] The power supply 3 at the bottom of the furnace 2 is in contact with the power supply 3 at the bottom of the furnace body 1 to supply electricity, so that the heating element 5 at the outer wall and bottom of the furnace 2 can be energized.

[0034] Specifically, the bread holder is a first bread holder; the first bread holder includes a first bottom bearing bar 311, a bottom bearing block 312 and an elastic net 313; a plurality of bottom bearing blocks 312 are evenly arranged on the top of the first bottom bearing bar 311, and both sides of the bottom bearing blocks 312 are curved upward; elastic nets 313 are installed on both sides of the heating chamber, and the vertical surface of the elastic net 313 is arc-shaped, and the elastic net 313 protrudes toward the first bottom bearing bar 311. Food is placed on the top surface of the plurality of bottom bearing blocks 312, and the elastic net 313 positions both sides of the food. At the same time, the elastic net 313 can prevent the food from touching the furnace 2, and can keep it clean and ensure the quality of the food. The elastic net 313 protrudes toward the first bottom bearing bar 311, and the protruding part of the elastic net 313 can hold the food, so as to avoid the elastic net 313 from contacting the food in a large range, and the food dripping residue and oil stains are on the elastic net 313, which can keep it clean. The food can be held by the protruding part of the elastic net 313. The food is clamped by the elastic nets 313 on both sides, which is convenient for the user to take out the food from the interior of the furnace 2. The two sides of the bottom bearing block 312 are curved upward to facilitate holding food. The number of the bottom bearing blocks 312 installed on the first bottom bearing bar 311 is 6-12.

[0035] Specifically, component 4 is a first driving member 41; the first driving member 41 includes a fixed column 411, a slider 412, an insert block 413, a paddle 414, a first spring 415 and a first electromagnet; the fixed column 411 is vertically installed inside the furnace body 1, the slider 412 and the first spring 415 are sleeved on the fixed column 411, the slider 412 slides up and down at the fixed column 411, and the first spring 415 is located below the slider 412; one side of the furnace 2 and one side of the furnace body 1 are matched to open an opening for the insert block 413 to pass through; one end of the insert block 413 passes through the opening of the furnace 2 and can be removably inserted into one side of the first bottom bearing bar 311, the middle part of the insert block 413 can slide through the slider 412, and the other end of the insert block 413 passes through the opening of the furnace body 1 and extends out of the furnace body 1; the paddle 414 is connected to one end of the insert block 413 extending out of the furnace body 1; the bottom of the furnace body 1 is correspondingly installed with a first electromagnet, and when the first electromagnet is energized, it adsorbs the first bottom bearing bar 311 and moves downward. After the first electromagnet is powered on, the magnetic field formed has an attraction force on the first bottom bearing bar 311 of stainless steel that is greater than the elastic force of the first spring 415, so that the first bottom bearing bar 311 is sucked to the bottom, and the bread slices at the first bottom bearing bar 311 also drop into the interior of the furnace 2 to heat the food. After the heating is completed, the first electromagnet is powered off, and the first spring 415 pops up the first bottom bearing bar 311, making it easier for the user to take out the food. The first electromagnet is not shown in the figure. The user can also adjust the position of the first bottom bearing bar 311 by moving the paddle 414. When the furnace 2 needs to be cleaned, just pull the plug 413 out of the first bottom bearing bar 311 and then exit the furnace 2, and the furnace 2 can be taken out for cleaning. The operation is simple and it is easy to disassemble the furnace 2 for cleaning.

[0036] Specifically, the component 4 is a second driving member 42; the second driving member 42 includes a second electromagnet 421 and a second spring 422; the two ends of the second spring 422 are respectively connected to the bottom surface of the furnace body 1 and the bottom surface of the bread bracket; the second electromagnet 421 is installed at the corresponding positions of the bottom surface of the furnace body 1 and the bottom surface of the bread bracket; the second electromagnet 421 is energized to move the bread bracket downward, and the second electromagnet 421 is de-energized, and the second spring 422 pushes the bread bracket upward. Without disassembling other components, the furnace 2 is more convenient to disassemble, and when cleaning the furnace 2, it saves more disassembly time.

[0037] Specifically, the bread holder is a second bread clamp; the second bread clamp includes a second bottom bearing bar 321 and springs 322, a plurality of springs 322 are evenly installed on both sides of the second bottom bearing bar 321, and gaps are formed between the springs 322 and the springs 322; the middle and bottom of the vertical section of the springs 322 are arc-shaped, the raised side of the springs 322 is installed toward the second bottom bearing bar 321, and the top of the springs 322 is vertically arranged; the second electromagnet 421 and the second spring 422 are installed at the bottom of the second bottom bearing bar 321. Food can be placed in the springs 322 on both sides for clamping, and the food is heated in the furnace 2, which is convenient for food placement, and the springs 322 are easy to clean.

[0038] Specifically, the bread holder is a third bread clamping rack; the third bread clamping rack includes a third bottom bearing bar 331 and an elastic line 332, a plurality of elastic lines 332 are evenly installed on both sides of the third bottom bearing bar 331, and gaps are formed between the elastic lines 332 and the elastic lines 332; the middle and bottom of the vertical section of the elastic line 332 are arc-shaped, the convex side of the elastic line 332 is installed toward the third bottom bearing bar 331, and the top of the elastic line 332 is vertically arranged; the bottom of the third bottom bearing bar 331 is installed with a second electromagnet 421 and a second spring 422. Food can be placed in the elastic lines 332 on both sides for clamping, and the food is heated in the furnace 2, which is convenient for food placement, and the elastic lines 332 are easy to clean.

[0039] It is understandable that the heating element 5 includes an insulating layer 51 and a heating film 52. The insulating layer 51 is provided with two pieces, and the two insulating layers 51 are arranged in affixed manner. The side wall of the two insulating layers 51 is printed with a heating film 52. The insulating layer 51 is made of a silicon dioxide and resin composite, and the heating film 52 is made of an alloy material such as silver palladium. The toasters on the market use metal heating wires as heat sources. The heating wires are directly wound on the surface of the Mika board in the form of bare wires, and then assembled in the toaster body. The bread slice cavity formed by the metal mesh together constitutes the heating cavity. After power is turned on, the heating wire generates heat to heat the temperature of the inner cavity, thereby achieving the effect of heating the bread slices. However, this heating technology has the following shortcomings: the heating wire is exposed to the air and directly powered on for heating, and the heating life is short. The heating wire is naked and charged during operation, which will cause safety hazards. The heating wire has a small heating area, and the temperature difference inside the furnace is large, so the food cannot be heated evenly. The furnace and other electrical components are non-detachable and cannot be cleaned. Bread slice fragments and dust have serious health hazards. The heating film 52 and the metal substrate are separated by an insulating layer 51, and at the same time, an insulating layer 51 is arranged outside the heating film 52, thereby ensuring that the entire furnace 2 is not electrified and there is no safety hazard of electric shock. By adjusting the temperature of the heating film, the internal temperature of the furnace 2 is ensured to be uniform. The furnace 2 is arranged as a detachable independent component, which is convenient for cleaning and maintenance after use.

[0040] A manufacturing process for a heating element, firstly printing an insulating layer on the outer wall of a furnace, sintering and curing the insulating layer at high temperature, then printing or screen-printing a heating alloy on the insulating layer in the form of a slurry, sintering and curing at high temperature again, and finally printing an insulating layer on the metal heating film again, sintering and curing at high temperature again, thereby completing the manufacturing of the heating element. The printed heating film has a longer life than the toaster currently on the market that uses a metal heating wire as a heat source. The toaster on the market uses a metal heating wire as a heat source. The heating wire is directly wound on the surface of a Mika board in the form of a bare wire, and then assembled with the toaster body. The bread slice cavity formed by the metal mesh together constitutes a heating cavity. After power is turned on, the heating wire generates heat to heat the temperature of the inner cavity, thereby achieving the effect of heating the bread slice. However, this heating technology has the following shortcomings: the heating wire is exposed to the air and directly powered on for heating, the heating life is short, the heating wire is naked and charged during operation, which will cause safety hazards, the heating area of ​​the heating wire is small, the temperature difference inside the furnace is large, and the food cannot be heated evenly. There is an insulating layer between the heating film and the metal substrate, and an insulating layer is printed outside the heating film, thereby ensuring that the entire furnace 2 is not electrified and there is no safety hazard of electric shock. By adjusting the printing of the heating film, the temperature inside the furnace is ensured to be uniform. The furnace 2 is designed as a detachable independent component, which is convenient for cleaning and maintenance after use.
