Detailed Description

The invention is further illustrated by means of examples which follow, without thereby restricting the scope of the invention thereto.

As shown in fig. 1, a discharging cavity comprises a containing cavity 100 for containing liquid and a liquid outlet passage 200 for communicating the containing cavity 100 with the outside, wherein the containing cavity 100 comprises a liquid containing area 110 and an air pressure chamber 120 above the liquid containing area 110. The air pressure chamber 120 referred to herein is a space kept relatively closed to the outside, so that the air pressure chamber 120 can change air pressure when the air is pumped out or filled in, and further realize start and stop of discharging.

The discharge chamber further includes an air intake passage 300 for connecting the pump-up and air-filling device, the air intake passage 300 opening into the housing chamber 100 and extending to the air pressure chamber 120, the air intake passage 300 opening into the housing chamber 100 at a position remote from the top wall of the housing chamber 100.

Since the air intake passage 300 is distant from the top wall of the receiving chamber 100, the overall height of the cooking machine is reduced, thereby reducing the volume of the entire cooking machine. On the other hand, the liquid charging operation is more convenient because the liquid charging operation of the accommodating chamber 100 does not collide with the air intake passage 300.

Further, in this embodiment, the top wall of the accommodating cavity 100 is designed to be flush with the top wall of the housing of the cooking machine, and the top of the accommodating cavity 100 is made of a transparent material, so that the appearance can be more concise by adopting the design, the liquid adding operation is more convenient, and meanwhile, the seasoning allowance in the accommodating cavity 100 can be conveniently observed. The use is more convenient.

Referring to fig. 1 and 4, in the present embodiment, the inlet of the air inlet channel 300 is led into the accommodating cavity 100 from the bottom of the sidewall of the accommodating cavity 100, the air inlet channel 300 extends to the air pressure chamber 120 through the liquid accommodating area 110, and the outlet 310 of the air inlet channel 300 is located in the air pressure chamber 120. That is, the air intake passage 300 is entirely built in the accommodating chamber 100, so that the volume occupation can be further reduced. The reason why the intake passage 300 is provided to enter the side wall bottom of the accommodation chamber 100 is that: because hold the chamber 100 and need throw in the condiment in the cooking pot, it must be in higher position in whole cooking machine, set up the access position of air inlet channel 300 in the lateral wall bottom that holds chamber 100 can reduce the external trachea length of intercommunication air inlet channel 300, convenient overall arrangement to reduce the probability that leads to equipment trouble because of external trachea gas leakage or distortion winding.

In this embodiment, the outlet 310 of the air inlet passage 300 extends to the top wall of the air pressure chamber 120. With such a layout, the outlet 310 of the air inlet passage 300 is spaced far from the level of the seasoning, so that the seasoning is prevented from entering the air inlet passage 300 due to shaking of the level or splashing of the liquid. The reliability is improved.

In this embodiment, the air inlet 300 includes an outlet section 320 extending horizontally along the top wall of the air pressure chamber 120, and the outlet 310 of the air inlet 300 is connected to the outlet section 320, and a baffle 330 extending vertically upwards and semi-shielding the outlet 310 is disposed at the outlet 310. The baffle 330 can further block splattered seasoning from entering the air intake passage 300, thereby further reducing the failure probability of the whole set of equipment.

In this embodiment, the top wall of the air pressure chamber 120 is provided with a filling opening 500 staggered with the outlet 310, and the filling opening 500 is provided with a detachable sealing cover, which can ensure that the air pressure chamber 120 is in a closed state. The liquid adding port 500 and the outlet 310 are staggered, so that the influence of splashed seasonings in the liquid adding process on the air inlet channel can be avoided.

In this embodiment, as shown in fig. 1, the liquid outlet passage 200 is a siphon passage, which has a liquid inlet 210 communicating with the liquid container and a liquid outlet 220 below the liquid container 110, and has a siphon outlet 230 always above the liquid level of the liquid container 110.

The siphon port 230 is a node position of the liquid outlet passage 200 which generates a siphon force to the liquid in the containing chamber 100 when the liquid outlet passage 200 is in a siphon state, and in the present invention, the siphon port 230 is at the highest point in the liquid outlet passage 200.

The pumping and inflating device is a device capable of switching operation between pumping and inflating states, and further description is omitted herein because such a device is conventional in the art.

With reference to fig. 2 and 3, the present discharge chamber realizes quantitative discharge by: when the seasoning is required to be discharged, the pumping and inflating device fills the air into the accommodating cavity 100 until the liquid in the liquid accommodating area 110 fills the whole liquid outlet passage 200 under the action of air pressure, and inflation is stopped, at this time, under the action of siphoning, the liquid in the liquid accommodating area 110 can automatically flow out to the outside through the liquid outlet passage 200, and the effect of quantitatively discharging the liquid seasoning can be realized only by controlling the outflow time of the liquid because the flow rate of the liquid outlet passage 200 is constant. In addition, it should be further noted that, in order to ensure continuous discharging of the liquid seasoning, the accommodating cavity 100 is actually provided with a one-way valve that can enable the external air to enter the accommodating cavity 100 and isolate the internal air from entering the outside.

When it is necessary to stop the discharge, the air pumping and inflating device pumps air into the accommodating chamber 100 until air flowing into the liquid outlet passage 200 from the outside under the action of air pressure passes through the siphon port 230. At this point the siphon effect ceases and the liquid seasoning in the outlet passage 200 falls under gravity and the seasoning ceases to be discharged. In addition, since the height of the siphon port 230 is always higher than the liquid containing area 110, even if the air pressure in the containing chamber 100 is restored to the outside air pressure, the seasoning in the liquid containing area 110 will not cross the siphon port 230, and can be stably maintained in a stopped discharging state.

The advantage of this liquid outlet channel 200 is: the liquid seasoning is discharged under the action of the siphon effect, the flow is stable, and the discharging precision is high. The pumping and inflating device is not in a working state in the seasoning discharging process, a high-precision air pump is not needed, and cost reduction is facilitated. The switching of discharging state can be realized by pumping and filling a small amount of gas, the switching speed is high, and the discharging time can be accurately mastered. After stopping discharging, no liquid exists in the siphon passage, so that the deposition and even blockage of impurities possibly occurring due to long-term storage of the liquid seasoning are avoided, the liquid seasoning is stored, and the outflow of the liquid seasoning possibly caused by air pressure fluctuation is avoided.

In this embodiment, the liquid outlet channel 200 comprises an inverted U-shaped section, and the top of the inverted U-shaped section is the siphon port 230. The inverted U-shaped section sequentially comprises an ascending section 240 and a descending section 250 along the liquid flowing direction, wherein the bottom of the ascending section 240 is communicated with the liquid inlet 210, and the bottom of the descending section 250 is communicated with the liquid outlet 220. That is, the inverted U-shaped section constitutes the liquid outlet passage 200 itself. By adopting the structure, on one hand, the length of the liquid outlet passage 200 can be shortened, the response speed is improved, the blanking time can be controlled more accurately, and the higher blanking precision is realized. On the other hand, with such a structure, when discharging is stopped by the suction method, the liquid can fall down to the level of the liquid accommodating area 110 by gravity after entering the descending section 250 over the siphon port 230. Therefore, the discharging can be stopped only by leading the liquid to pass through the siphon port 230 through the air suction operation, and the device has high operation precision allowance and is convenient for production debugging. Meanwhile, the probability that the discharging cannot be stopped due to the fact that the precision is reduced after the pumping and inflating device is used for a long time can be reduced.

In this embodiment, the liquid outlet passage 200 is surrounded by a liquid outlet chamber 400, and the liquid outlet chamber 400 and the accommodating chamber 100 are integrated. This reduces space occupation, reduces the probability of damage to the liquid outlet passage 200 from the external environment, and improves overall reliability.

In this embodiment, the tapping chamber 400 configures the tapping channel 200 by: the liquid outlet chamber 400 is divided into a first chamber 410 communicating with the outside and a second chamber 420 communicating with the liquid accommodating area 110 by a vertical partition 430, the vertical partition 430 extends vertically to a position higher than the liquid accommodating area 110, and a space is formed between the top of the vertical partition 430 and the top wall of the liquid outlet chamber 400, and the first chamber 410 and the second chamber 420 form the liquid outlet passage 200.

In this embodiment, the liquid outlet chamber 400 is square tube-shaped extending along the height direction of the accommodating chamber 100, and the reason for adopting this design is that: since the amount of liquid seasoning to be discharged is small, usually within 10ml, in order to be able to precisely control the amount of liquid seasoning to be discharged, the flow rate per unit time of liquid seasoning should be reduced to extend the time of discharging, thereby obtaining higher control accuracy. The use of the square tubular liquid outlet chamber 400 enables the liquid outlet passage 200 to have a smaller cross-sectional area. And further, larger control precision can be obtained. In addition, the use of the square tubular liquid outlet chamber 400 can be more preferably manufactured in a large scale by punching or the like. Of course, it is equally possible that the outlet chamber 400 has a circular tube shape.

In this embodiment, the liquid outlet 220 is connected to the liquid outlet pipe 221, and the outer wall of the accommodating cavity 100 of the liquid outlet pipe 221 extends outwards, so that the liquid outlet pipe 221 arranged in a protruding manner can prevent the liquid seasoning from flowing down along the outer wall of the accommodating cavity 100 under the wall attaching effect, which is beneficial to improving the blanking precision.

The invention also provides a quantitative blanking mechanism which comprises the discharging cavity, and the quantitative blanking mechanism also has the advantages of small volume, convenient use, high precision, high response speed and low cost.

The invention also provides a cooking machine which comprises the quantitative discharging mechanism, can accurately realize liquid seasoning discharging and has the advantages of small volume, convenient use and low cost.
