Description

Technical Field

[0001] The utility model relates to the technical field of kitchen appliances, in particular to an electric pizza oven. Background Art

[0002] Heating pizza requires uniform heat transfer and effective heating from top to bottom, so a dedicated pizza oven is required. Existing electric pizza ovens typically use metal heating coils to heat food, using metals like iron-chromium or nickel-chromium wires to generate heat when electricity is applied. This results in low heating efficiency, resulting in long cooking times. Furthermore, when the pizza oven is operating, the temperature inside the oven remains above 300°C for extended periods, making it susceptible to damage to electronic components such as the power supply and controller. This shortens the oven's lifespan and can cause the outer shell to overheat, potentially causing harm to the user. Utility Model Content

[0036] Reference Figures 1 to 9One embodiment of the present invention provides an electric pizza oven, which includes an inner tank 100, a heating component, a baking tray 140, an inner shell 200, and an outer shell 300. The inner tank 100 is provided with a baking cavity 110. The front side wall 170 of the inner tank 100 is provided with an opening connected to the baking cavity 110. The inner tank 100 is also movably connected to a door body 400 that can open or close the opening. The heating component includes a graphene heating tube 120 and a metal heating coil 130. The graphene heating tube 120 is installed at the top of the baking cavity 110, and the metal heating coil 130 is installed at the bottom of the baking cavity 110. The baking tray 140 can be inserted into the baking cavity 110 and is located between the graphene heating tube 120 and the metal heating coil 130. The inner housing 200 is mounted over the outer periphery of the inner liner 100. A heat-insulating cavity 210 is defined between the inner and outer walls of the inner housing 200. A heat-insulating assembly wrapped around the outer periphery of the inner liner 100 is installed within the heat-insulating cavity 210. The outer housing 300 is mounted over the outer periphery of the inner housing 200. A mounting cavity 310 for mounting electronic components is defined between the inner and outer walls of the outer housing 300. The bottom wall of the outer housing 300 is provided with multiple heat dissipation holes.

[0037] By adopting the electric pizza oven of the present invention, the heating component uses a graphene heating tube 120 and a metal heating coil 130 to cooperate with each other. The graphene heating tube 120 can heat the food from above the baking tray 140, while the metal heating coil 130 can heat the food from below the baking tray 140. The metal heating coil 130 generates heat by passing electricity through the metal and conducts the heat to the food through the baking tray 140, that is, heating the food by heat conduction. The graphene heating tube 120 utilizes the extremely high thermal conductivity of graphene to quickly convert electrical energy into thermal energy. The heat generated by the graphene heating tube 120 is not only conducted to the food through the baking tray 140, but also generates infrared rays when the graphene is heated, thus achieving infrared heating. That is, the graphene heating tube 120 can heat the food through both thermal radiation and heat conduction, greatly improving the heat transfer efficiency, shortening the heating time of the food, and helping to lock in the moisture in the food, making the food taste better. In addition, the electric pizza oven of the embodiment of the present invention is also provided with an inner shell 200, and a heat insulation cavity 210 is formed between the inner shell 200 and the inner tank 100, and an installation cavity 310 for installing electronic components is formed between the inner shell 200 and the outer shell 300. The heat insulation component in the heat insulation cavity 210 can well isolate the heat in the baking cavity 110, which is beneficial to keep the baking cavity 110 warm and prevent the heat in the baking cavity 110 from being conducted to the installation cavity 310, thereby helping to reduce the risk of damage to the electronic components in the installation cavity 310 due to high temperature. At the same time, the installation cavity 310 can also play a heat insulation effect, further preventing heat from being conducted to the outer shell 300, thereby reducing the risk of burns to the user due to the excessive temperature of the outer shell 300, thereby protecting the user. By opening a plurality of heat dissipation holes at the bottom of the outer shell 300, the hot air in the installation cavity 310 can flow out from the bottom of the outer shell 300 through the heat dissipation holes. This not only can dissipate heat from the installation cavity 310, further reduce the temperature in the installation cavity 310, and reduce the risk of damage to electronic components in the installation cavity 310 due to high temperature, but also can effectively prevent the hot air flowing out of the installation cavity 310 from blowing directly onto the user and causing harm to the user, thus having higher safety performance.

[0038] It is understandable that the inner liner 100 , the inner shell 200 , and the outer shell 300 can all be made of 304 stainless steel.

[0039] It is understandable that by using the graphene heating tube 120, graphene has an extremely high thermal conductivity coefficient and can quickly convert electrical energy into thermal energy, thus also having a high electrical energy conversion efficiency, thereby making the heating component more energy-efficient and power-saving. In addition, graphene also has good stability, which enables the graphene heating tube 120 to have a long service life. Among them, the graphene heating tube 120 can specifically include a glass tube and a graphene heating element. The graphene heating element is installed in the glass tube, and the two ends of the glass tube are provided with power terminals for electrically heating the graphene.

[0040] It can be understood that since the heating efficiency of the metal heating coil 130 is lower than that of the graphene heating tube 120, in order to further shorten the baking time of food, when the baking tray 140 is inserted into the baking cavity 110, the distance between the baking tray 140 and the metal heating coil 130 can be smaller than the distance between the baking tray 140 and the graphene heating tube 120. This can shorten the time for the heat emitted by the metal heating coil 130 to be conducted to the food through the baking tray 140, thereby facilitating the metal heating coil 130 to heat the food in the baking tray 140, which is beneficial to shortening the baking time of food and improving the overall heating efficiency of the electric pizza oven.

[0041] Reference Figures 1 to 9 In some embodiments, an electronic control device 320 is installed in the installation cavity 310, and the connection terminals of the graphene heating tube 120 and the connection terminals of the metal heating coil 130 both pass through the insulation cavity 210 and extend into the installation cavity 310 to be electrically connected to the electronic control device 320.

[0042] By adopting the above structure and installing the electronic control device 320 within the mounting cavity 310, the thermal insulation assembly within the thermal insulation cavity 210 can effectively isolate the heat within the baking cavity 110, preventing the heat within the baking cavity 110 from being transferred into the mounting cavity 310. This helps protect the electronic control device 320 and reduces the risk of damage to the electronic control device 320 due to high temperatures. In addition, by extending the electrical terminals of the graphene heating tube 120 and the wiring terminals of the metal heating coil 130 into the mounting cavity 310, the impact of high temperatures on the electrical terminals of the graphene heating tube 120 and the wiring terminals of the metal heating coil 130 can be reduced, which is beneficial to the normal operation of the graphene heating tube 120 and the metal heating coil 130.

[0043] Reference Figures 1 to 4In some embodiments, the door body 400 includes a door frame, a first insulating glass 410, a second insulating glass 420 and an outer layer of glass. The door frame is hinged to the side wall of the inner liner 100, and the first insulating glass 410, the second insulating glass 420 and the outer layer of glass are installed on the door frame in sequence from back to front; the front side wall 170 of the inner liner 100 is installed with a sealing strip 150, which is arranged around the outer periphery of the opening. The front side wall 170 of the inner liner 100 is also provided with a forward-protruding abutting portion 160. When the door body 400 closes the opening, the first insulating glass 410 abuts against the abutting portion 160 and the sealing strip 150.

[0044] By adopting the above structure, the arrangement of the first insulating glass 410 and the second insulating glass 420 can effectively isolate the heat within the baking chamber 110, preventing the outer glass from overheating and affecting user use, thereby causing burns. In addition, the sealing strip 150 cooperates with the first insulating glass 410 to seal the baking chamber 110, thereby preventing heat from escaping from the baking chamber 110 through the opening. The abutment portion 160 prevents the first insulating glass 410 from directly colliding with the front side wall 170 of the inner container 100 when the door 400 is closed. This protects the first insulating glass 410 and the inner container 100, preventing the first insulating glass 410 from breaking or the front side wall 170 of the inner container 100 from deforming.

[0045] It is understandable that the abutting portion 160 can be made of flexible materials such as rubber and silicone.

[0046] It is understandable that the first insulating glass 410 can specifically be made of borosilicate glass. Borosilicate glass has very excellent thermal insulation properties, and thus can well isolate the heat in the baking cavity 110, preventing the temperature of the outer layer of glass from being too high and affecting the user's use, causing burns to the user. In addition, borosilicate glass has a low thermal expansion coefficient, so it can maintain good stability at high temperatures. Secondly, borosilicate glass has high thermal shock resistance and can withstand rapid temperature changes without breaking, thereby maintaining good structural stability during the use of the electric pizza oven. Of course, in addition to this, the first insulating glass 410 can also be made of other types of glass, and the present invention does not make specific limitations on this.

[0047] It is understood that the second insulating glass 420 can specifically be Low-E glass, also known as low-emissivity glass. Low-E glass is a glass surface coated with multiple layers of metal or other compounds. This coating layer has high transmittance for visible light and high reflectivity for mid- and far-infrared radiation, resulting in excellent thermal insulation and light transmittance. It can reflect the infrared radiation emitted by the graphene heating tubes 120 back into the baking chamber 110, effectively isolating the temperature within the baking chamber 110 and further improving the heating efficiency of the graphene heating tubes 120 for food. Of course, other types of glass may also be used for the first insulating glass 410, and this is not specifically limited in this invention.

[0048] It is understandable that, referring to Figures 1 to 4 In some embodiments, the outer glass layer is provided with an observation port 431, through which a user can conveniently observe the heating status of food in the baking cavity 110. When the second insulating glass 420 is Low-E glass, due to its high transmittance to visible light, the user can more clearly observe the heating status of food in the baking cavity 110. It is understood that the outer glass layer can specifically be decorative glass 430 commonly used in the prior art, and this is not specifically limited in the present invention.

[0049] It is understandable that, referring to Figures 1 to 4 In some embodiments, a handle 470 is further mounted on the front surface of the outer glass sash, and a strip-shaped light-emitting portion 471 is provided on the handle 470. In this structure, the provision of the handle 470 facilitates the user to open or close the door 400. The provision of the light-emitting portion 471 not only facilitates the user to accurately grasp the handle 470 to open or close the door 400, but also enhances the aesthetics of the electric pizza oven. To further enhance the aesthetics of the electric pizza oven, the light-emitting portion 471 can be configured to produce a horse racing effect or other lighting effects, which are not specifically limited by the present invention.

[0050] Reference Figures 1 to 4 In some embodiments, a cooling fan is installed in the installation cavity 310, and the outer shell 300 defines a cold air inlet connected to the installation cavity 310. A first communication hole 171 communicating with the installation cavity 310 is defined on the front sidewall 170 of the inner liner 100. A heat dissipation channel 440 is formed between the first and second heat-insulating glass panels 410 and 420. A hot air inlet 441 communicating with the heat dissipation channel 440 is defined on the upper sidewall of the door frame. The hot air inlet 441 communicates with the first communication hole 171, and the lower end of the heat dissipation channel 440 has a hot air outlet 442 communicating with the outside.

[0051] By adopting the above structure, the provision of a heat dissipation fan can accelerate air flow within the installation cavity 310, allowing hot air within the installation cavity 310 to flow out quickly. This helps cool the electronic components within the installation cavity 310, further reducing the risk of damage to the electronic components within the installation cavity 310 due to high temperatures. It also further reduces the risk of burns to the user due to excessive temperature of the outer shell 300. Furthermore, by providing a heat dissipation channel 440 between the first insulating glass 410 and the second insulating glass 420, hot air within the installation cavity 310 can flow through the first connecting hole 171 into the heat dissipation channel 440, flow downward along the heat dissipation channel 440, and finally flow out of the hot air outlet 442 at the lower end of the heat dissipation channel 440, thereby facilitating the exhaust of hot air within the installation cavity 310. Furthermore, by locating the hot air outlet 442 at the lower end of the heat dissipation channel 440, the hot air flows out from the lower end of the door body 400, thereby preventing the hot air flowing out of the installation cavity 310 from directly blowing onto the user and causing harm.

[0052] Because the baking chamber 110 is sealed when the electric pizza oven is heating food, the air and moisture inside the baking chamber 110 expand due to the heat, forming high-temperature, high-pressure gas. If the high-temperature, high-pressure gas is not discharged in time, it will cause excessive pressure inside the baking chamber 110. When the food is heated, the moment the door 400 is opened, the high-temperature, high-pressure gas inside the baking chamber 110 will quickly diffuse due to the large pressure difference between the inside and outside of the baking chamber 110, which can easily cause harm to the user.

[0053] For this purpose, refer to Figures 1 to 4 In some embodiments, the front side wall 170 of the inner container 100 further defines a second communication hole 172 communicating with the heat insulation cavity 210. The second communication hole 172 communicates with the hot air inlet 441. The upper side wall of the inner container 100 defines a third communication hole 180 communicating with the baking cavity 110. An air outlet box 220 is installed within the heat insulation cavity 210. The air outlet box 220 has an air outlet cavity 221 communicating with the third communication hole 180. The air outlet cavity 221 extends forward to communicate with the second communication hole 172.

[0054] By adopting the above structure, during the process of heating food in the electric pizza oven, the high-temperature and high-pressure gas in the baking chamber 110 can flow into the air outlet chamber 221 of the air outlet box 220 through the third connecting hole 180, and then flow into the heat dissipation channel 440 of the door body 400 through the second connecting hole 172, and finally be discharged from the hot air outlet 442 at the lower end of the heat dissipation channel 440. This can reduce the pressure difference between the inside and outside of the baking chamber 110 at the moment the door body 400 is opened, and can guide the high-temperature and high-pressure gas to flow out from the lower end of the door body 400, thereby reducing the risk of high-temperature and high-pressure gas causing harm to the user, thereby improving the user experience.

[0055] Reference Figures 1 to 4 In some embodiments, the door frame includes two oppositely arranged side mounting plates 450450 and an upper mounting plate 460460 connected between the upper ends of the two side mounting plates 450450, the two side mounting plates 450450 are hinged to the front side wall 170 of the inner tank 100, the hot air inlet 441 is opened on the upper mounting plate 460460, the first insulating glass 410 and the second insulating glass 420 are both installed between the two side mounting plates 450450 and abut against the upper mounting plate 460460, the outer layer of glass is installed on the front side surfaces of the two side mounting plates 450450 and extends upward relative to the upper mounting plate 460460, the front side of the outer shell 300 is installed with a forward extending decorative panel 330, the decorative panel 330 is at least partially located above the first connecting hole 171 and the second connecting hole 172, when the door body 400 closes the opening, the outer layer of glass is adjacent to the decorative panel 330.

[0056] By adopting the above structure, the two side mounting plates 450450 facilitate the stable installation of the first insulating glass 410, the second insulating glass 420, and the outer glass, while the upper mounting plate 460460 facilitates the processing and opening of the hot air inlet 441. By extending the outer glass upward relative to the upper mounting plate 460460 to block the first and second connecting holes 171, 172, the hot air exhausted from the first and second connecting holes 171, 172 is blown directly toward the door body 400. The door body 400 then blocks the hot air exhausted from the first and second connecting holes 171, 172, diverting it to the hot air inlet 441 of the upper mounting plate or into the gap between the outer glass and the decorative panel 330. Thus, the outer glass prevents the hot air exhausted from the first and second connecting holes 171, 172 from blowing directly toward the user, reducing the possibility of harm from the hot air and thereby improving the user experience.

[0057] It can be understood that the first insulating glass 410 and the second insulating glass 420 are both installed between the two side mounting plates 450450 and abut against the upper mounting plate 460460. Specifically, each side mounting plate 450450 is installed with at least one clamping portion, and the clamping portion is provided with a first clamping groove and a second clamping groove. The first insulating glass 410 is clamped in the first clamping groove, and the second insulating glass 420 is clamped in the second clamping groove. The clamping portion can be installed on the side mounting plate 450450 by screwing, clamping or welding, and when at least two clamping portions are installed on each side mounting plate 450450, the clamping portions are arranged in sequence along the upper and lower directions of the side mounting plate 450450.

[0058] It can be understood that the outer layer of glass is installed on the front side surfaces of the two side mounting plates 450450. Specifically, the outer layer of glass can be installed on the front side surfaces of the two side mounting plates 450450 by bonding.
