Description

Technical Field

[0001] The invention relates to the field of automatic cooking machines, and in particular to a discharging cavity, a liquid seasoning discharging device and a cooking machine. Background Art

[0002] The liquid seasoning discharge chamber of the existing cooking machine adopts manual feeding or pumping to extract and feed. When feeding manually, a built-in scale is used to weigh and determine the weight of the liquid seasoning. When the pump body is extracted, each liquid seasoning is extracted by a water pump, or a water pump extracts different liquid seasonings through a reversing valve.

[0003] In the process of manually adding seasoning, due to the limited accuracy of human hands, it is often impossible to accurately control the amount, or a lot of time is wasted.

[0004] When the pump body extracts liquid seasonings, if a water pump is used for each liquid seasoning, the cost is high, the control is more complicated, and the error rate is high. If a water pump is used to extract different liquids through a reversing valve, the cost of the reversing valve will increase as the number of liquid seasonings increases, and when a water pump extracts different liquids, the liquids will be mixed, affecting the cooking experience.

[0005] At the same time, since liquid seasoning has a high viscosity and contains a large amount of colloid, it is easy to scale in the water pump and the water pump pipes, resulting in reduced flow rate of the water pump and reduced feeding accuracy. In severe cases, it may even cause the water pump to be blocked and unable to feed. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defects of the prior art such as high cost, complex control and easy scaling and clogging, and to provide a discharging cavity, a liquid seasoning discharging device and a cooking machine.

[0007] The present invention solves the above technical problems through the following technical solutions:

[0008] A discharge chamber comprises a receiving chamber for placing liquid and a liquid discharge passage connecting the receiving chamber with the outside, the discharge chamber also comprises a liquid discharge part detachably connected to the receiving chamber, the liquid discharge passage is arranged in the liquid discharge part, the receiving chamber comprises a liquid receiving area and a gas pressure chamber located above the liquid receiving area, the gas pressure chamber is used to connect a pumping and charging device, the liquid discharge passage is a siphon passage, and the liquid discharge passage has a siphon port which is always higher than the liquid receiving area. The advantages of the present invention are that the liquid seasoning is discharged under the action of the siphon effect, the flow rate is stable, and the discharge accuracy is high. The pumping and charging device is not in a working state during the seasoning feeding process, and a high-precision air pump is not required, which is conducive to reducing costs. The switching of the discharge state can be achieved by pumping and charging a small amount of gas, the switching speed is fast, and the discharge time can be more accurately grasped. After stopping the discharge, there is no liquid in the section of the siphon passage from the outlet to the siphon port, which avoids the deposition of impurities or even blockage that may occur due to the long-term storage of liquid seasoning. The liquid outlet passage is arranged in a liquid outlet part which is detachably connected to the accommodating chamber. After being used for a period of time, the scale in the liquid outlet passage can be cleaned by disassembling and cleaning the liquid outlet part, so that the liquid outlet passage can always maintain the designed flow rate, thereby achieving long-term high-precision use.

[0009] Preferably, the accommodating chamber and the liquid outlet are connected via a detachable portion, and a connecting passage connecting the accommodating chamber and the liquid outlet is provided in the detachable portion. The detachable portion is a sleeve pipe, a screw pipe or a clamp pipe, thereby achieving a detachable connection between the accommodating chamber and the liquid outlet.

[0010] Preferably, the horizontal position of the detachable part corresponds to the bottom of the liquid containing area. With such a structure, the liquid seasoning in the liquid containing area can be completely drained, which reduces waste and reduces the frequency of adding seasoning.

[0011] Preferably, the liquid outlet passage comprises an inverted U-shaped section, and the top of the inverted U-shaped section is the siphon port.

[0012] Preferably, the liquid outlet portion has a liquid outlet chamber, the liquid outlet chamber has a partition so as to separate the liquid outlet chamber into a first chamber and a second chamber, and the top position of the partition has a connecting port connecting the first chamber and the second chamber. Compared with setting a pipeline structure, such a structure has the advantages of being easy to manufacture and easy to control the size, and can more easily achieve the designed flow rate. In addition, since the liquid outlet portion is a rigid structure as a whole, it is less likely to deform during cleaning than a directly tubular liquid outlet portion, and can still maintain the original designed flow rate after multiple cleanings, thereby ensuring the accuracy of use.

[0013] Preferably, the accommodating cavity has an air inlet passage for connecting the pumping and charging device, and the air inlet passage enters the accommodating cavity from the side of the accommodating cavity and extends upward to the air pressure chamber. Since the air inlet passage is away from the top wall of the accommodating cavity, the overall height of the cooking machine is reduced, thereby reducing the volume of the entire cooking machine. On the other hand, when adding liquid to the accommodating cavity, there will be no collision with the air inlet passage, and the liquid adding operation is more convenient.

[0014] Preferably, the air inlet passage passes into the accommodating cavity from the bottom of the side wall of the accommodating cavity and extends through the liquid accommodating area to the air pressure chamber.

[0015] Preferably, the outlet of the air intake passage is located at the top of the air pressure chamber. Such a layout can ensure a greater distance between the outlet of the air intake passage and the level of the seasoning liquid, thereby preventing the seasoning from entering the air intake passage due to the shaking of the liquid level or the splashing of the liquid, thereby improving reliability.

[0016] Preferably, the air inlet passage includes an outlet section extending horizontally along the top wall of the air pressure chamber, the outlet of the air inlet passage is connected to the outlet section, and a baffle extending vertically upward and semi-covering the outlet is provided at the outlet. The baffle can further block splashing seasoning from entering the air inlet passage, thereby further reducing the probability of failure of the entire equipment.

[0017] A liquid seasoning discharging device comprises a discharging cavity as described above and a pumping and charging device, wherein the pumping and charging device is connected to the air pressure chamber of the discharging cavity.

[0018] A cooking machine comprises the liquid seasoning discharging device as described above.

[0019] The positive and progressive effects of the present invention are: the liquid seasoning is discharged under the action of the siphon effect, the flow rate is stable, and the discharge accuracy is high. The pumping and charging device is not in a working state during the seasoning discharge process, and there is no need to use a high-precision air pump, which is conducive to reducing costs. The discharge state can be switched by pumping and charging a small amount of gas, and the switching speed is fast, and the discharge time can be grasped more accurately. After the discharge is stopped, there is no liquid in the section of the siphon passage from the outlet to the siphon port, avoiding the deposition of impurities or even blockage that may occur due to the long-term storage of liquid seasoning. The liquid outlet passage is arranged in a liquid outlet part that is detachably connected to the accommodating chamber. After a period of use, the scale in the liquid outlet passage can be cleaned by disassembling and cleaning the liquid outlet part, so that the liquid outlet passage can always maintain the designed flow rate, and long-term high-precision use can be achieved.

[0038] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0039] like Figure 1 As shown, a discharging cavity is used for discharging liquid seasoning, which includes a containing cavity 100 for placing the liquid seasoning and a liquid outlet passage 210 connecting the containing cavity 100 with the outside.

[0040] The accommodating chamber 100 is closed, and includes a liquid accommodating area and a pneumatic chamber located above the liquid accommodating area, and the pneumatic chamber is used to connect a pumping and inflation device. The pumping and inflation device referred to here is a device that can pump air or inflate air into the pneumatic chamber. The device can be an integrated pumping and inflation structure, or a separate pumping and inflation device that works in coordination. Since such devices are common prior art, they will not be further described herein. The present invention preferably uses an integrated pumping and inflation device that is smaller in size and more convenient to control.

[0041] The discharge chamber also includes a liquid discharge portion 200 detachably connected to the accommodating chamber 100, and the liquid discharge passage 210 is disposed in the liquid discharge portion 200. The liquid discharge passage 210 is a siphon passage, and the liquid discharge passage 210 has a siphon port 211 that is always higher than the liquid accommodating area. The siphon port 211 referred to here refers to the node position that generates a siphon force on the liquid in the accommodating chamber 100 when the liquid discharge passage 210 is in a siphon state. In the present invention, the siphon port 211 is located at the highest point of the entire liquid discharge passage 210. After the liquid passes the highest point, it can flow out along the liquid discharge passage 210 by itself under the drag of gravity, so that the siphon effect can continue uninterruptedly.

[0042] The working mode of this discharge chamber is as follows:

[0043] like Figure 2 As shown, when the seasoning needs to be discharged, the pumping and charging device fills the air pressure chamber with gas until the liquid in the liquid containing area enters the liquid outlet passage 210 under the action of the air pressure until the siphon effect starts, and the charging is stopped. At this time, under the action of the siphon, the liquid in the liquid containing area can flow out through the liquid outlet passage 210 by itself, thereby realizing the seasoning discharge.

[0044] like Figure 3 As shown, when it is necessary to stop discharging, the pumping and inflation device pumps out the gas in the air pressure chamber until the air in the liquid outlet passage 210 converges under the action of air pressure and thus interrupts the siphon effect.

[0045] When the siphon effect stops, the liquid between the siphon port 211 and the outlet 252 of the discharge passage drops to a position flush with the liquid surface in the liquid containing area due to gravity. Since the siphon port 211 is always higher than the liquid containing area, the liquid between the siphon port 211 and the outlet 252 of the discharge passage cannot pass through the siphon port 211 to produce the siphon effect, and thus can be stably maintained in the stopped discharge state.

[0046] Since the feeding amount of liquid seasoning is small, usually within 10ml, in order to accurately control the feeding amount, in actual design, the flow rate of liquid seasoning per unit time should be appropriately reduced to appropriately extend the feeding time, thereby improving the feeding accuracy. However, this also leads to a thinner pipe diameter of the liquid outlet passage 210. It is more likely to cause scaling and clogging problems. Therefore, the present invention places the liquid outlet passage 210 separately in the liquid outlet part 200 detachably connected to the accommodating chamber 100. After a period of use, it can be removed for cleaning, thereby solving the problem of scaling and clogging of the seasoning during long-term use. The discharge chamber can always maintain a good working accuracy.

[0047] In summary, the advantages of the present invention are: liquid seasoning is discharged under the action of the siphon effect, the flow rate is stable, and the discharge accuracy is high. The pumping and charging device is not in a working state during the seasoning feeding process, and there is no need to use a high-precision air pump, which is conducive to reducing costs. The switching of the discharge state can be achieved by pumping and charging a small amount of gas, and the switching speed is fast, and the discharge time can be grasped more accurately. After stopping the discharge, there is no liquid in the section of the siphon passage from the outlet 252 to the siphon port 211, which avoids the deposition of impurities and even blockage that may occur due to the long-term storage of liquid seasoning. The liquid outlet passage 210 is arranged in the liquid outlet part 200 detachably connected to the accommodating chamber 100. After a period of use, the scale in the liquid outlet passage 210 can be cleaned by disassembling and cleaning the liquid outlet part 200, so that the liquid outlet passage 210 can always maintain the designed flow rate, and achieve long-term high-precision use.

[0048] In this embodiment, the accommodating chamber 100 and the liquid outlet 200 are detachably connected in the following manner: the accommodating chamber 100 and the liquid outlet 200 are connected via a detachable portion 300, and a connecting passage connecting the accommodating chamber 100 and the liquid outlet 200 is provided in the detachable portion 300. The detachable portion 300 may be a sleeve pipe, a screw pipe, a clamp pipe, or the like.

[0049] In this embodiment, the horizontal position of the detachable part 300 corresponds to the bottom of the liquid containing area. Specifically, the detachable part 300 is arranged at the bottom of the side wall of the containing cavity 100. With such a structure, the liquid seasoning in the liquid containing area can be completely drained, reducing waste and reducing the frequency of adding seasoning. The detachable part 300 is arranged at the side wall of the containing cavity 100, which is easier to disassemble than the bottom of the containing cavity 100, and can facilitate the user to perform disassembly and assembly operations.

[0050] In this embodiment, the liquid outlet passage 210 includes an inverted U-shaped section, the top of which is the siphon port 211, and the inverted U-shaped section is composed of a gradually ascending section 212 extending from the inlet of the liquid outlet passage 210 to the siphon port 211, and a gradually descending section 213 extending from the siphon port 211 to the outlet 252 of the liquid outlet passage 210. After the siphon action stops, the liquid in the gradually descending section 213 can fall down by itself under the action of gravity and flow out from the outlet 252 of the liquid outlet passage 210, and will not stay therein, so as to avoid the seasoning from drying up and blocking the liquid outlet passage 210 due to long-term non-use.

[0051] In this embodiment, the liquid outlet 200 is disposed on the side of the accommodating chamber 100 and a gap is left between the liquid outlet 200 and the accommodating chamber 100, so that when disassembling, space can be left for the liquid outlet 200 to move left and right to facilitate disassembly.

[0052] In the present embodiment, a liquid outlet chamber is provided in the liquid outlet portion 200, and a partition 220 is provided in the liquid outlet chamber to separate the liquid outlet chamber into a first chamber 230 and a second chamber 240 arranged in parallel, and a connecting port for connecting the first chamber 230 and the second chamber 240 is provided on the top of the partition 220. The first chamber 230 and the second chamber 240 connected to each other constitute the liquid outlet passage 210. Compared with setting a pipeline structure, such a structure has the advantages of being easy to manufacture and easy to control the size, and can more easily achieve the designed flow rate. In addition, since the liquid outlet portion 200 is a rigid structure as a whole, it is not easy to deform during cleaning compared with the directly tubular liquid outlet portion 200, and can still maintain the original designed flow rate after multiple cleanings, thereby ensuring the accuracy of use.

[0053] In this embodiment, the discharge chamber also includes an air intake passage 250 for connecting to the pumping and charging device. The air intake passage 250 passes into the accommodating chamber 100 and extends to the air pressure chamber. The position where the air intake passage 250 enters the accommodating chamber 100 is away from the top wall of the accommodating chamber 100.

[0054] Since the air inlet passage 250 is away from the top wall of the accommodating chamber 100, the overall height of the cooking machine is reduced, thereby reducing the volume of the entire cooking machine. On the other hand, when adding liquid to the accommodating chamber 100, there will be no collision with the air inlet passage 250, and the liquid adding operation is more convenient.

[0055] Furthermore, in this embodiment, the top wall of the accommodating cavity 100 is designed to be flush with the top wall of the cooking machine housing, and the top of the accommodating cavity 100 is made of a transparent material. This design can make the appearance more concise, the liquid adding operation more convenient, and it is also convenient to observe the remaining seasoning in the accommodating cavity 100. It is more convenient to use. The liquid outlet 200 is also configured to be a cylinder with the accommodating cavity 100, so that the user can easily insert a finger into the gap between the liquid outlet 200 and the accommodating cavity 100 to remove the liquid outlet 200.

[0056] In this embodiment, the inlet of the air inlet passage 250 enters the accommodating chamber 100 from the bottom of the side wall of the accommodating chamber 100, and the air inlet passage 250 extends through the liquid containing area to the air pressure chamber, and the outlet 252 of the air inlet passage 250 is located in the air pressure chamber. In other words, the air inlet passage 250 is built into the accommodating chamber 100 as a whole, so that the volume occupied can be further reduced. The reason why the air inlet passage 250 is set to enter from the bottom of the side wall of the accommodating chamber 100 is that since the accommodating chamber 100 needs to put seasoning into the cooking pot, it must be at a higher position in the entire cooking machine. Setting the access position of the air inlet passage 250 at the bottom of the side wall of the accommodating chamber 100 can reduce the length of the external air pipe connected to the air inlet passage 250, facilitate layout, and reduce the probability of equipment failure due to leakage or twisting of the external air pipe.

[0057] In this embodiment, the outlet 252 of the air inlet passage 250 extends to the top wall of the air pressure chamber. This layout allows the outlet 252 of the air inlet passage 250 to be spaced farther from the surface of the seasoning liquid, thereby preventing the seasoning from entering the air inlet passage 250 due to the shaking of the liquid surface or the splashing of the liquid, thereby improving reliability.

[0058] In this embodiment, the air inlet passage 250 includes an outlet 252 section 251 extending horizontally along the top wall of the air pressure chamber, and the outlet 252 of the air inlet passage 250 is connected to the outlet 252 section 251. A baffle 253 extending vertically upward and semi-shielding the outlet 252 is provided at the outlet 252. The baffle 253 can further block the splashing seasoning from entering the air inlet passage 250, thereby further reducing the probability of failure of the entire equipment.

[0059] In this embodiment, a liquid filling port is arranged on the top wall of the air pressure chamber, which is staggered with the outlet 252. A detachable sealing cover is provided on the liquid filling port, which can ensure that the air pressure chamber is in a closed state. The liquid filling port is staggered with the outlet 252 to prevent the splashing seasoning from affecting the air inlet channel during the liquid filling process.

[0060] The present invention also provides a liquid seasoning discharging device, comprising a discharging chamber as described above and a pumping and charging device, the pumping and charging device being connected to the air pressure chamber of the discharging chamber. The liquid seasoning discharging device has the advantages of being not easy to be scaled and blocked, small in size, easy to use, high in precision, fast in response speed, and low in cost.

[0061] The present invention also provides a cooking machine, comprising the liquid seasoning discharging device described above.

[0062] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
