Detailed Description

The present invention will now be described in further detail with reference to the following figures and detailed description .

As shown in figures 1 and 2, the embodiment specifically provides full-automatic wheaten food machines, which comprise a main machine 1 with a control unit inside, a stirring component and an extrusion component 22 installed on the main machine, wherein the stirring component comprises a stirring cup 2 and a stirring rod 21 arranged in the stirring cup, a mounting seat 11 is arranged on the main machine, a water storage tank 3 is arranged on the mounting seat, a water outlet 31 is arranged at the bottom of the water storage tank, a water inlet hole 23 is arranged at the upper part of the stirring cup, the water outlet is connected with the water inlet hole of the stirring cup through a connecting pipeline 4, so that the stored water in the water storage tank can flow out from the water outlet and flows into the stirring cup from the water inlet hole through the connecting pipeline.

When the wheaten food is made, a proper amount of flour can be put into the stirring cup, at the moment, a control system of the wheaten food machine can calculate the required water amount, then the electromagnetic valve is opened to conduct the connecting pipeline, water in the water storage tank can flow into the stirring cup through the connecting pipeline, and the detection unit can detect the discharged water amount so as to close the electromagnetic valve in time, thereby accurately controlling the required water amount.

It should be noted that, for the pasta machine capable of automatically adding water, a weighing sensor can be arranged inside the main machine to detect the weight of the stirring cup. When flour is put into the stirring cup, the weighing sensor can output a weight signal of the stirring cup at the moment, and the control unit can conveniently obtain the actual weight of the flour by calculating the front and back weight difference of the stirring cup. In addition, the detection unit can be a timing module capable of detecting the water outlet time, a liquid level sensor capable of detecting the liquid level of the water storage tank and other cheap devices, so that the cost is reduced.

It is known that the pressure of the water outlet at the bottom of the water storage tank is equal to the sum of the atmospheric pressure and the water pressure formed by the water depth in the water storage tank, since standard atmospheric pressures are basically equal to the pressure of 10 meters of water depth, and the water depth of the water storage tank is basically within 20 centimeters, namely, the water pressure of the water storage tank can be basically ignored, the pressure of the water outlet can be basically equal to the atmospheric pressure, so that the flow rate of the water outlet can be kept stable as much as possible, and in addition, in the aspect of , the water outlet has enough pressure to ensure the smoothness of the water flow at the water outlet.

Certainly, as shown in fig. 3, the water storage tank may also be a sealed tank, and at this time, vent pipes 32 may be arranged at the top of the water storage tank, the end of the vent pipe is communicated with the inner cavity of the water storage tank, the end of the vent pipe is communicated with the outside air, and the electromagnetic valve is arranged on the vent pipe to control the on-off of the vent pipe.

When the water quantity fed into the stirring cup reaches the amount matched with the flour, the electromagnetic valve is closed when the control unit stops, the vent pipe is cut off, the upper part of the water storage tank forms a seal, the water level in the water storage tank can be continuously reduced by the water flow at the water outlet, and negative pressure is formed at the upper part of the water storage tank, so that the pressure of the water outlet is reduced until the water flow at the water outlet stops, and the water outlet of the water storage tank is controlled.

The control unit obtains the required water quantity according to the input flour quantity, then subtracts the lag water quantity from the required water quantity to obtain corrected water quantities, and when the signal output by the detection unit reaches the corrected water quantity value, the control unit can close the electromagnetic valve to ensure the accuracy of the water quantity output by the water storage tank.

In order to add water into the water storage tank conveniently, as shown in fig. 4, the water storage tank comprises a water adding port 33 arranged at the upper part, a rotating seat 34 arranged at the side of the water adding port, and a sealing tank cover 35 covering the water adding port, wherein the side of the sealing tank cover is hinged with the rotating seat through a rotating shaft, a torsion spring for fixing the sealing tank cover is arranged on the rotating shaft, and the sealing tank cover is tightly attached to and covers the water adding port under the elastic action of the torsion spring.

When the water level reaches the set water level, the sealing box cover can be loosened, and the torsion spring can enable the sealing box cover to automatically turn over to cover the water filling port, so that the problem that the sealing box cover is forgotten to be covered is solved.

Preferably, the magnetic blocks 351 are respectively arranged at corresponding positions on the outer edges of the water filling port and the sealed box cover. When the torsion spring enables the sealing box cover to cover the water filling port, the magnetic suction block enables the sealing box cover to be reliably positioned, the sealing box cover is prevented from bouncing off by itself, and water storage is prevented from leaking from the water filling port when the water storage tank shakes.

When the water storage tank is a sealed tank body, an elastic sealing gasket 352 can be arranged on the inner side of the sealing tank cover, which is close to the water filling opening, so that the sealing tank cover is hermetically covered on the water filling opening, and the sealing of the water storage tank is ensured.

When the wheaten food is made, the control unit firstly calculates the amount of water required to be added according to the weight of flour, obtains the opening time of the electromagnetic valve according to the input relational expression, and then can accurately control the opening time of the electromagnetic valve through the timing module, so that the amount of water flowing out of the water outlet is accurately controlled. The timing module has simple structure and low cost, so the structure and the control program of the wheaten food machine can be greatly simplified, and the production cost is effectively reduced.

It is known that when the water level in the water storage tank is gradually reduced, the water pressure at the water outlet of the water storage tank is gradually reduced, and correspondingly, the flow rate at the water outlet is also reduced.

When the height of the water storage tank is H, the height of the lowest set termination water level is H, as a second preferred scheme, the ratio of the height H of the lowest set termination water level to the height H of the water storage tank can be controlled within the following range that H/H is more than or equal to 0.4 and less than or equal to 0.6, so that the water storage tank has enough volume, the cross section of the water storage tank is increased as much as possible under the height of the water storage tank determined by , the water level difference between the initial water level and the termination water level is reduced, the flow speed difference of a water outlet is reduced, the accurate control of the water outlet amount is facilitated, and the increase of the overall dimension of the pasta machine due to the overla.

As a third preferred solution, as shown in fig. 5, the detection unit is a liquid level sensor 6 disposed in the water storage tank, and the liquid level sensor can conveniently detect the initial water level and the final water level in the water storage tank. When the wheaten food is made, the liquid level sensor outputs an initial water level signal to the control unit, the control unit calculates the final water level of the water storage tank according to the required water quantity and the size of the cross section of the water storage tank, and then the electromagnetic valve is opened to convey water into the stirring cup. When the water level in the water storage tank reaches the stop water level, the liquid level sensor outputs a corresponding electric signal to the control unit, and the control unit at the moment can close the electromagnetic valve so as to realize accurate control of the output water quantity and avoid water accumulation in the connecting pipeline. Of course, we should keep the cross section of the tank constant so that the calculations of the control unit can be accurately controlled.

As a fourth preferred scheme, the detection unit is a weight sensor which is arranged on the main machine and can detect the weight of the water storage tank. When the pasta is made, the weight sensor outputs an initial weight signal of the water storage tank to the control unit, and the control unit calculates the final weight of the water storage tank according to the water amount matched with the amount of the flour put in. When the weight of the water storage tank is gradually reduced to the ending weight, the weight sensor outputs an ending weight signal of the water storage tank to the control unit, and the control unit can close the electromagnetic valve at the moment so as to realize accurate control of the output water quantity,

as a fifth preferred scheme, the detection unit is a flow meter arranged on a connecting pipeline connecting the water storage tank and the stirring cup. When the cooked wheaten food is made, when the flow of the water outlet detected by the flowmeter reaches the required water amount calculated by the control unit, the control unit can close the stop valve so as to accurately control the water amount output by the water storage tank.
