Description

Technical Field

[0001] This utility model relates to the field of electric pizza oven technology, and in particular to a door structure for an electric pizza oven. Background Technology

[0002] Electric pizza ovens are mostly exported to European and American markets. Their operating temperature can reach 400-500 degrees Celsius, requiring them to meet the product safety standards of the corresponding export regions. Traditional electric pizza ovens use cooling ducts on the outside of the cooking cavity to remove heat radiated outwards, ensuring the surface temperature of the casing meets safety standards.

[0003] The original electric pizza oven's glass door design allowed for easy viewing of the cooking chamber. However, with the EU revising safety standards, specifically increasing the requirements for shell surface temperature, the existing electric pizza oven doors cannot pass the corresponding safety tests. Therefore, the structure of the electric pizza oven urgently needs improvement. Utility Model Content

[0004] The purpose of this invention is to provide a door structure for an electric pizza oven that reduces the temperature of the outer surface of the oven door.

[0005] The purpose of this utility model is achieved as follows.

[0006] The electric pizza oven uses a door structure, including an oven body and an oven door. The bottom of the oven door and the oven body are connected by a hinge. The oven door includes an outer glass layer, a first partition glass layer, a second partition glass layer, and an inner glass layer, which are arranged sequentially from the outside to the inside on a fixed component. A first heat dissipation channel is formed between the outer glass layer and the first partition glass layer, and a second heat dissipation channel is formed between the second partition glass layer and the first partition glass layer. The second partition glass layer and the inner glass layer form a heat insulation cavity, and a heat dissipation vent is provided at the top of the heat insulation cavity.

[0007] Furthermore, the fixing assembly includes two L-shaped brackets, two fixing brackets, a pressure sleeve, and a fixing plate. The two fixing brackets are symmetrically arranged on the left and right. The two fixing brackets have two fixing grooves vertically arranged along the height direction on opposite sides. The ends of the first and second partition glass are locked in the corresponding fixing grooves. The front end of the fixing bracket has a slot near the outside. The two L-shaped brackets are symmetrically arranged on the left and right. One end of the L-shaped bracket is connected and fixed to the back of the outer glass. The inner end of the L-shaped bracket is inserted into the slot. The L-shaped bracket and the fixing bracket are connected and fixed by a first fastener. The rear part of the fixing bracket has an installation groove. The inner glass is fixed in the installation groove. The fixing plate fixes the bottom surface of the fixing bracket and supports the first partition glass, the second partition glass, and the inner glass. The pressure sleeve is fixed to the top of the fixing bracket and is placed on the first partition glass, the second partition glass, and the inner glass.

[0008] Furthermore, the pressure sleeve includes a top plate, a rear plate, and two side plates. The front ends of the top plate and the side plates abut against the back of the outer glass. The front end of the top plate is provided with a first concave notch. The top plate is provided with a first through hole and a second through hole behind the first concave notch. The tops of the first and second partition glass abut against the bottom surface of the top plate. The first partition glass separates the first concave notch and the first through hole. The second partition glass separates the first through hole and the second through hole. The first concave notch forms the outlet of the first heat dissipation channel. The first through hole forms the outlet of the second heat dissipation channel. The second through hole forms the heat dissipation opening.

[0009] Furthermore, the top plate and the inner side of the rear plate are provided with positioning walls, the front end of the positioning wall abuts against the back of the second partition glass, the bottom of the positioning wall abuts against the top of the inner glass, and the bottom of the rear plate extends to the back of the top of the inner glass.

[0010] Furthermore, a positioning block is provided at the bottom of the side plate. The positioning block is inserted into the corresponding slot, and a first fastener fixes the positioning block, the L-shaped bracket and the fixed bracket together.

[0011] Furthermore, the bottom of the fixed bracket is provided with a fixing hole, and the left and right ends of the fixing plate and the fixing hole are connected and fixed by a second fastener. The front end of the fixing plate is provided with a second concave notch, and the bottom of the first partition glass is placed on the second concave notch. The bottom of the first partition glass is placed on the fixing plate behind the second concave notch. The second concave notch forms the entrance of the first heat dissipation channel and the second heat dissipation channel.

[0012] Furthermore, the rear end of the fixing piece is bent upward to form a limiting block, which extends to the back of the bottom of the inner glass layer.

[0013] Furthermore, the fixed bracket has a mounting hole along the height direction in the middle for fixing one end of the hinge.

[0014] Furthermore, the furnace body is equipped with a heat dissipation duct. The inlet of the heat dissipation duct is located at the front end of the furnace body, above the furnace door. The outlets of the first heat dissipation channel and the second heat dissipation channel are connected to the inlet of the heat dissipation duct. The heat insulation cavity is connected to the inlet of the heat dissipation duct through the heat dissipation port.

[0015] This invention's oven door utilizes a four-layer glass design, two heat dissipation channels, and a heat insulation cavity to effectively reduce the temperature of the outer glass. While retaining the ability to view the cooking cavity, the electric pizza oven door passes EU safety product testing. The fixed component structure design facilitates the installation of the four-layer glass and forms two heat dissipation channels and a heat insulation cavity. Attached Figure Description

[0022] Example 1, see Figure 1-5 As shown, an electric pizza oven door structure includes an oven body 1 and an oven door 2, with the bottom of the oven door 2 connected to the oven body 1 via a hinge 3. The oven door 2 includes an outer glass layer 21, a first partition glass layer 22, a second partition glass layer 23, and an inner glass layer 24, which are sequentially arranged from the outside to the inside on a fixing assembly 4.

[0023] The fixing component 4 includes two L-shaped brackets 5, two fixing brackets 6, a pressure sleeve 7, and a fixing plate 8. The two fixing brackets 6 are symmetrically arranged on the left and right sides, and two fixing grooves 61 are vertically provided on one side of the two fixing brackets 6 facing each other along the height direction. The left and right ends of the first partition glass 22 and the second partition glass 23 are engaged in the corresponding fixing grooves 61, and the first partition glass 22 and the second partition glass 23 are spaced apart. The front end of the fixing bracket 6 has a slot 62 near the outer side. The two L-shaped brackets 5 are symmetrically arranged on the left and right sides. One end of the L-shaped bracket 5 is connected and fixed to the back of the outer glass 21 (e.g., by adhesive layer). The inner end of the L-shaped bracket 5 is inserted into the slot 62. The L-shaped bracket 5 and the fixing bracket 6 are connected and fixed by a first fastener (e.g., screw, not shown in the figure). The rear of the fixing bracket 6 has a mounting groove 63, and the left and right ends of the front of the inner glass 24 are adhesively fixed in the corresponding mounting grooves 63.

[0024] The pressure sleeve 7 is fixed to the top of the fixed bracket 6 and is placed on the first partition glass 22, the second partition glass 23, and the inner glass 24. Specifically, the pressure sleeve 7 includes a top plate 71, a rear plate 72, and two side plates 73. The front ends of the top plate 71 and the side plates 73 abut against the back of the outer glass 21. The front end of the top plate 71 is provided with a first concave notch 74, and the top plate 71 is provided with a first through hole 75 and a second through hole 76 behind the first concave notch 74. The tops of the first partition glass 22 and the second partition glass 23 abut against the bottom surface of the top plate 71. The first partition glass 22 separates the first concave notch 74 and the first through hole 75, and the second partition glass 23 separates the first through hole 75 and the second through hole 76. The inner sides of the top plate 71 and the rear plate 72 are provided with a positioning wall 77. The front end of the positioning wall 77 abuts against the back of the second partition glass 23, the bottom of the positioning wall 77 abuts against the top of the inner glass 24, and the bottom of the rear plate 72 extends to the top and back of the inner glass 24. A positioning block 78 extends downward from the bottom of the side plate 73. The positioning block 78 is inserted into the corresponding slot 62, and a first fastener fixes the positioning block 78, the L-shaped bracket 5, and the fixing bracket 6 together. Preferably, the pressure sleeve 7 is integrally formed. In this embodiment, there are multiple first through holes 75 arranged in a row, and multiple second through holes 76 arranged in a row, with the first through holes 75 and the second through holes 76 staggered.

[0025] The fixing plate 8 secures the bottom surface of the fixing bracket 6, supporting the first partition glass 22, the second partition glass 23, and the inner glass 24. Specifically, the fixing bracket 6 has a fixing hole 64 at its bottom. The left and right ends of the fixing plate 8 and the fixing hole 64 are connected and fixed by a second fastener (such as a screw, not shown in the figure). The front end of the fixing plate 8 has a second concave notch 81, and the bottom of the first partition glass 22 rests on the second concave notch 81, and the bottom of the first partition glass 22 rests on the fixing plate 8 behind the second concave notch 81. The rear end of the fixing plate 8 bends upward to form a limiting block 82, which extends to the back of the bottom of the inner glass 24. In this embodiment, the fixing hole 64 extends vertically from the bottom of the fixing bracket 6 to the top of the fixing bracket 6. The back plate of the pressure sleeve 7 and the limiting block 82 limit the inner glass 24 within the mounting groove 63.

[0026] The fixed bracket 6 has a mounting hole 65 in the middle along the height direction. One end of the hinge 3 is inserted into the mounting hole 65 from the bottom of the fixed bracket 6. Part of the first fastener connects the fixed bracket 6 and the L-shaped bracket 5, and also connects and fixes one end of the hinge 3. This reduces the number of assembly parts and assembly steps, improving production efficiency.

[0027] A handle 9 is provided at the top front of the outer glass 21. After the furnace door 2 is installed, a vertical first heat dissipation channel 20 is formed between the outer glass 21 and the first partition glass 22. The first concave notch 74 constitutes the outlet of the first heat dissipation channel 20, and the second concave notch 81 constitutes the inlet of the first heat dissipation channel 20. A vertical second heat dissipation channel 30 is formed between the second partition glass 23 and the first partition glass 22. The first through hole 75 constitutes the outlet of the second heat dissipation channel 30, and the second concave notch 81 constitutes the inlet of the second heat dissipation channel 30. The second partition glass 23 and the inner glass 24 form a heat insulation cavity 40. The bottom of the heat insulation cavity 40 is sealed by a fixing piece 8, and the second through hole 76 constitutes the heat dissipation vent at the top of the heat insulation cavity 40.

[0028] In this embodiment, a heat dissipation duct 11 is provided inside the oven body 1. The inlet of the heat dissipation duct 11 is located at the front end of the oven body 1, above the oven door 2. The outlets of the first heat dissipation channel 20 and the second heat dissipation channel 30 are connected to the inlet of the heat dissipation duct 11. The heat insulation cavity 40 is connected to the inlet of the heat dissipation duct 11 through a heat dissipation vent. The fan 12 inside the heat dissipation duct 11 draws external airflow into the heat dissipation duct 11 from the inlet, and also draws airflow from the first heat dissipation channel 20 and the second heat dissipation channel 30 into the heat dissipation duct 11. External airflow is also replenished into the first heat dissipation channel 20 and the second heat dissipation channel 30 from the bottom of the oven door 2. The air in the heat insulation cavity 40 is exchanged with the heat dissipation duct 11 through the heat dissipation vent, thereby reducing the heat conducted from the cooking cavity 13 to the outer glass 21.
