The invention will be further described in detail in combination with drawings and examples.
As shown in
A chassis assembly 16, wherein the chassis assembly 16 is connected with the automobile;
A cabinet arranged above the chassis assembly 16, the cabinet consists of a lower cabinet 1, an upper rear cover assembly 3 and a front cover assembly 2 which are arranged oppositely, and is provided with a barbecue ovencavity for accommodating a food grate 5; the upper rear cover assembly 3 and the front cover assembly 2 are hinged through a hinge kit 13, one side of the lower cabinet 1 is provided with a side table assembly 6 extending in the horizontal direction, and one side of the front cover assembly 2 is connected with the side table assembly 6 in the lower cabinet 1 through an air spring support 12; and the side of the front cover assembly 2 is provided with a hook support 11 which can be fixedly connected with the lower cabinet 1.
In practical use, the barbecue oven can be configured in a first form in which the barbecue ovencavity is isolated from the outside when the front cover assembly 2 is closed; or configured in a second form in which the barbecue ovencavity is communicated with the outside when the front cover assembly 2 is open, so as to meet different needs during use of the barbecue oven. For example, the second form is workable when trailers travel and the barbecue oven heats to keep driving safety and heating effect; and the first form is workable when the barbecue oven works and goods are exhibited for sale, so that the goods can be accessed and exhibited conveniently.
When the barbecue oven is switched between the two forms, the front cover assembly 2 can move relative to the lower cabinet 1 along an articulated shaft of the hinge kit 13, and the air spring support 12 moves with the front cover assembly 2 during the movement to provide support for the front cover assembly 2, exposing/closing the barbecue ovencavity for holding the food grate for barbecue ovening.
In one example, an edge 9 composed of steel bars 10 is arranged in the barbecue ovencavity along the boundary extension direction of the lower cabinet constituting the barbecue ovencavity, specifically comprising a left edge side 7 and a right edge side 8, for providing support to the front cover assembly 2 when the barbecue oven is traveling with the vehicle and when the barbecue oven is turned off, preventing relative sliding from exposing the barbecue ovencavity and affecting the barbecue oven temperature and barbecue ovening effect.
The mobile pellet fueled variable frequency barbecue oven further comprises a feeding mechanism assembly 15. The feeding mechanism assembly 15 comprises a fuel tank assembly 4 communicated with the barbecue ovencavity and a feeding pipe, pellet fuel supporting operation of the barbecue oven is stored in the fuel tank assembly 4, one end of the feeding pipe is communicated with the fuel tank assembly 4, the other end of the feeding pipe is communicated with the barbecue ovencavity, and a feeding motor is arranged in the middle of the feeding pipe. When the barbecue oven works, pellet fuel in the fuel tank assembly 4 is fed into the barbecue ovencavity through the feeding pipe for combustion to provide heat energy required for the barbecue oven.
The mobile pellet fueled variable frequency barbecue oven further comprises an electric cabinet assembly 14 arranged above the chassis assembly 16, both sides of the electric cabinet assembly 14 are electrically connected with the cabinet and the automobile power supply respectively to provide working power to the barbecue oven and control stable power supply of the barbecue oven, specifically, provide energy and control for the operation of a heating assembly, the feeding motor and an exhaust gas circulation assembly of the barbecue oven.
As shown in
An MCU processing circuit; said low voltage actuator connected with the MCU processing circuit for driving the MCU processing circuit to operate at a set power.
In one example, the low voltage actuator comprises a first branch, a second branch and a third branch which are electrically connected with the MCU processing circuit after being connected in parallel with each other. The first branch is connected with an appliance of the barbecue oven, and is provided with an inverter and batteries, the second branch is provided with an external power supply and a charging plug, and the third branch is connected with the automobile power supply.
During actual operation, the first branch of the low voltage actuator is connected to the power supply of the barbecue oven at the user side through the inverter and the batteries connected in parallel to convert alternating current supplied by the external power supply into direct current for normal operation of the barbecue oven so as to reduce the current supplied to the barbecue oven. Meanwhile, through the arrangement of the three branches and the control of the MCU processing circuit, the power supply of the barbecue oven can be flexibly switched under actual conditions. For example, batteries in the first branch are used to supply power when the automobile parks and the barbecue oven is taken out for normal work and sale; the automobile power supply in the third branch is used to supply power in the driving state or parking state of the automobile; and the external power supply in the second branch is used to supply power when a fixed external power supply is available, and the batteries in the first branch are charged when the second branch supplies power. Such multi-branch work mode can be switched and controlled by the MCU processing circuit controlled by an external input signal, which broadens the applicable scenarios of the vehicle-mounted barbecue oven and is more suitable for actual use requirements.
Preferably, a serial WIFI circuit can also be arranged in the control circuit, the serial WIFI circuit is in signal connection with the MCU processing circuit for data exchange with a drive circuit, so that the work state of the control circuit and the barbecue oven can be controlled and switched through a mobile terminal in real time, thus increasing the convenience of control. An overcurrent protection detection circuit can also be arranged, the overcurrent protection detection circuit is connected with the MCU processing circuit through an IO interface for receiving control data sent by the MCU processing circuit so as to prevent the barbecue oven or the control circuit from damaging the line due to the influence of circuit aging or abnormal current. A display circuit can also be arranged, the display circuit is electrically connected with the MCU processing circuit and comprises an LED display circuit and a passive buzzer circuit for audible and visual indication during operation, such as real-time monitoring and display of such operational data as working time, barbecue oven temperature, battery capacity and power supply voltage, and alarming when the set time is up or when the barbecue oven temperature is abnormal.
The invention further provides a mobile pellet fueled variable frequency barbecue oven comprising an electric cabinet assembly provided with the control circuit, the electric cabinet assembly comprises:
An electric cabinet; and a control circuit arranged in the electric cabinet, wherein the control circuit is electrically connected with the automobile power supply and an appliance of a user respectively.
