At present, according to different types of fuel, pizza ovens on the market include an electric pizza oven, a gas pizza oven, and a pellet fuel pizza oven. The electric pizza oven heats a baking chamber through an electric heating tube. The gas pizza oven heats a baking chamber through a gas assembly. The pellet fuel pizza oven heats a baking chamber through combustible pellets (such as carbon pellets and firewood pellets). The pizza ovens in all the forms can only use a single type of fuel, and the fuel cannot be replaced according to different usage environments.
In view of this, the present disclosure provides a pizza oven 100.
Referring to
According to this embodiment, the pizza oven 100 includes the oven body 1, and the pellet hopper 21, the gas assembly 22, and the electrical assembly 23 which are matched with the oven body 1 for use. The baking chamber 11 and the plug-in slot 12 connected to the baking chamber 11 are formed in the oven body 1. A pizza stone 111 is placed at a bottom of the baking chamber 11. The pizza stone 111 heats a pizza placed on the pizza stone 111 by absorbing heat inside the baking chamber 11. The plug-in slot 12 is configured to plug one of the pellet hopper 21, the gas assembly 22, and the electrical assembly 23.
The pellet hopper 21 is configured to hold a granular combustible material (such as carbon pellets and firewood pellets). After the granular combustible material is ignited with an ignition source, the pellet hopper 21 is plugged into the plug-in slot 12. Heat generated by the combustible material acts on the baking chamber 11, thereby achieving a first mode for baking a pizza. When the gas assembly 22 is plugged into the plug-in slot 12, after a gas cylinder is connected, a switch knob 225 is pushed and turned to an ignition position, thereby achieving a second mode for baking a pizza. When the electrical assembly 23 is plugged into the plug-in slot 12, after a power supply is connected, a switch on a circuit control assembly is turned on, and an electric heating tube 232 is switched on to generate heat, thereby achieving a third mode for baking a pizza.
It should be noted that the pellet hopper 21 is not fixedly connected to the oven body 1, making it easy to plug or remove the pellet hopper 21 at any time. The gas assembly 22 includes a gas shell 221; a first mounting piece 2211 is arranged on a peripheral side of the gas shell 221; and the first mounting piece 2211 is configured to be fixedly connected to a back plate of the oven body 1. When the gas assembly 22 is used for baking, the gas shell 221 is partially plugged into the plug-in slot 12 until the first mounting piece 2211 resists against the back plate of the oven body 1. The first mounting piece 2211 and the back plate of the oven body 1 are provided with corresponding threaded holes, and the first mounting piece 2211 is fixed to the oven body 1 by a screw. The electrical assembly 23 includes an electrical appliance shell 231; a second mounting piece 2311 is arranged on a peripheral side of the electrical appliance shell 231; and the second mounting piece 2311 is configured to be fixedly connected to a back plate of the oven body 1. When the electrical assembly 23 is used for baking, the electrical appliance shell 231 is at least partially plugged into the plug-in slot 12 until the second mounting piece 2311 resists against the back plate of the oven body 1. The second mounting piece 2311 and the back plate of the oven body 1 are provided with corresponding threaded holes, and the second mounting piece 2311 is fixed to the oven body 1 by a screw. When the gas assembly 22 or the electrical assembly 23 needs to be removed, only the screw needs to be removed.
In summary, compared with the conventional pizza oven 100, the pizza oven 100 has the advantages that fuel can be replaced according to a need, which is beneficial for expanding usage scenarios of the pizza oven 100 and achieving multiple purposes in one oven.
Referring to
Further, a chimney 4 is arranged at a top of the baking chamber 11, and a flue 19 is arranged inside the baking chamber 11. One end of the flue 19 is connected to the first opening, and the other end of the flue 19 tilts upwards and is connected to an upper space of the baking chamber 11. When the pellet hopper 21 or the gas assembly 22 is plugged into the plug-in slot 12, due to the effect of the chimney 4, flame will enter the baking chamber along the flue 19, and waste gas will be discharged along the chimney 4. It is not difficult to understand that if the flame directly acts on the pizza stone 111, food on the pizza stone 111 is easily burnt and has a scorched flavor, resulting in poor taste. Therefore, in this embodiment, the flue 19 is obliquely arranged, and the flame enters the upper space of the baking chamber through the flue 19, to heat the pizza stone 111 and the food on the pizza stone 111 from top to bottom to achieve a baking effect.
The embodiment of the pizza oven 100 further includes the a pellet fuel assembly; the pellet fuel assembly includes a feeding assembly 31 and an ash box 32; the feeding assembly 31 is arranged above the plug-in slot 12 and is connected to the plug-in slot 12; the ash box 32 is arranged below the plug-in slot 12 and is connected to the plug-in slot 12; and when the pellet hopper 21 is plugged into the plug-in slot 12, the feeding assembly 31 is configured to add pellet fuel into the pellet hopper 21; and the ash box 32 is configured to receive ash obtained after combustion of pellet fuel.
Specifically, referring to
A material outlet 18 is provided in a bottom wall of the plug-in slot 12 to connect the plug-in slot 12 to a chamber of the ash box 32. Referring to
The feeding tube 311 is obliquely arranged. When the pellet hopper 21 is plugged into the plug-in slot 12, the cover plate 312 is opened, and pellet fuel is poured into the feeding tube 311. The pellet fuel falls into the pellet hopper 21 and is stacked up to fill the feeding tube 311. Then, the cover plate 312 is closed. When the fuel at the bottom of the pellet hopper 21 is fully combusted into ash, the ash will fall into the ash box 32 after passing through the carrier plate 212. Meanwhile, a height of the fuel on the pellet hopper 21 decreases, and the fuel stacked in the feeding tube 311 falls off under the action of the gravity, thus continuously replenishing the fuel until the added fuel is combusted completely.
The ash box 32 is detachably connected to the bottom plate of the oven body 1 by, such as, screw connection and sliding chute connection. When the combustion quality of the pellet fuel is good (without producing too much ash), the ash box 32 can be removed, or when the ash box 32 is full of ash, the ash box 32 can be removed to discharge the ash.
Further, air inlet holes 2112 are provided in a back wall of the hopper body 211 to connect the second compartment 214 to an external environment. Environmental air can be blown from the air inlet 2112 towards the second compartment 214, and then flow into the first compartment 213 through the ash holes 2121, thereby improving the flowability of the air, supplementing oxygen, and improving the combustion efficiency of the pellet fuel.
A damper (not shown) can be arranged on the hopper body 211. The damper covers the air inlet hole 2112 and can slide up and down or left and right relative to the air inlet hole 2112, thereby adjusting a number or size of air inlet holes 2112 that are opened and adjusting an air intake volume.
A handle 2113 is arranged on aback wall of the hopper body 211, and the handle 2113 is detachably connected to the hopper body 211. A clamping seat is arranged on the back wall of the hopper body 211. An end portion of the handle 2113 is bent and provided with a clamping hook matched with the clamping seat. The clamping hook is plugged into the clamping seat and connected to the clamping seat. Thus, the handle 2113 can be used to push the hopper body 211 into or pull the hopper body 211 out of the plug-in slot 12. After being used, the handle 2113 can be removed from the clamping seat to prevent the operator from accidentally touching handle 2113 during operation and knocking over the pizza oven 100.
Referring to
Specifically, the first mounting piece 2211 divides the gas shell 221 into a first shell and a second shell. The first shell is plugged into the plug-in slot 12, and the second shell is exposed to the oven body 1. The air supply assembly includes an air supply tube 222, a stamping furnace end 223, and a safety valve 224. The safety valve 224 is arranged in a chamber of the second shell. The stamping furnace end 223 is arranged in a chamber of the first shell. An input end of the air supply tube 222 is configured to be connected to the gas cylinder, and an output end of the air supply tube 222 is connected to the safety valve 224. The output end of the safety valve 224 is connected to an input end of the stamping furnace end 223, and an output end of the stamping furnace end 223 extends into the baking chamber 11 through the first shell. The safety valve 224 is installed between the air supply tube 222 and the stamping furnace end 223 to control the opening and closing of the air supply tube 222. In addition, the gas assembly 22 further includes a thermoelectric flameout protection system. The thermoelectric flameout protection system has a thermocouple. The thermocouple cooperates with an electromagnetic valve inside the safety valve 224. When flame of the gas assembly 22 is extinguished due to an external reason, a temperature at an end of the thermocouple decreases, and sufficient electromotive force cannot be generated, so that the electromagnetic valve is controlled to be closed to prevent further gas leakage.
Referring to
The circuit control assembly has an overheating protection function. The circuit control assembly includes a temperature controller and a protector. The temperature controller is configured to monitor a temperature of the electric heating tube 232. When the temperature controller detects that the electric heating tube 232 is overheated, the protector controls a circuit to be switched off in a timely manner to maintain the electric heating tube within a normal working temperature range.
The above describes only preferable embodiments of the present disclosure and does not limit the patent scope of the present disclosure. Any equivalent structural transformations made using the specification and accompanying drawings of the present disclosure within the inventive concept of the present disclosure, or directly or indirectly applied in other related technical fields, all fall within the scope of patent protection of the present disclosure.
