Description

Technical Field

[0001] This invention relates to the field of cake-making technology, and in particular to a cake-making machine with a quantitative liquid dispensing function. Background Technology

[0002] In recent years, the popularity of food cooking appliances has been increasing, and many fully automatic cooking appliances with different uses have appeared on the market. For example, automatic pancake makers can automate the entire pancake-making process. Users only need to prepare ingredients such as flour and water, and the automatic pancake maker can automatically perform processes such as feeding, kneading, pressing, and heating to make fresh and delicious pancakes.

[0003] In the operation of an automatic pancake-making machine, flour is first automatically dispensed from the flour cup and water from the water cup via a feeding mechanism. The flour and water are then mixed and kneaded into dough by a dough-kneading mechanism, which then conveys the dough to a pressing and baking mechanism. Finally, the pressing and baking mechanism flattens the dough while simultaneously heating it to form a pancake. However, existing automatic pancake-making machines have difficulty in precisely metering the water or oil inlet mechanisms. During the pancake-making process, the ratio of water or oil in the dough cannot be accurately controlled, resulting in pancakes of unsatisfactory quality. Summary of the Invention

[0004] The main objective of this invention is to propose a cake-making machine with a quantitative liquid dispensing function, which aims to enable the cake-making machine to quantitatively dispense water and oil, thereby improving the cake-making quality.

[0005] To achieve the above objectives, the present invention proposes a cake-making machine with a quantitative liquid dispensing function, comprising:

[0006] The main body of the cake maker;

[0007] A liquid inlet mechanism is provided on the body of the cake making machine. The liquid inlet mechanism includes a liquid inlet housing and a valve core. The valve core is provided on the liquid inlet housing. The liquid inlet housing has a liquid storage chamber and a metering chamber. The metering chamber has a liquid inlet and a liquid outlet. The liquid inlet is connected to the liquid storage chamber.

[0008] The valve core is used to open the inlet and close the outlet, and to close the inlet and open the outlet.

[0009] In one embodiment, the valve core is movably disposed within the metering chamber, thereby giving the valve core a first position and a second position;

[0010] In the first position, the valve core opens the inlet and closes the outlet;

[0011] In the second position, the valve core closes the inlet and opens the outlet.

[0012] In one embodiment, the valve core further has a third position in which the valve core closes the inlet and the outlet.

[0013] In one embodiment, the valve core includes a first sealing plug, a second sealing plug, and a valve stem. The first sealing plug and the second sealing plug are both sleeved on the outer periphery of the valve stem. The first sealing plug is used to open or close the liquid inlet, and the second sealing plug is used to open or close the liquid outlet.

[0014] In one embodiment, the metering chamber includes an inlet chamber, a metering chamber, and an outlet chamber connected in sequence, wherein the inlet chamber has the inlet port and the outlet chamber has the outlet port;

[0015] A liquid inlet gap may be formed between the outer periphery of the first sealing plug and the second sealing plug and the inner wall of the metering chamber;

[0016] When the first sealing plug is located in the liquid inlet chamber, the first sealing plug blocks the liquid inlet from the metering chamber;

[0017] When the second sealing plug is located in the liquid outlet chamber, the second sealing plug blocks the liquid outlet from the metering chamber.

[0018] In one embodiment, a first transition section is formed between the inlet chamber and the metering chamber, and a second transition section is formed between the metering chamber and the outlet chamber, wherein both the first transition section and the second transition section are chamfered.

[0019] In one embodiment, the cake maker further includes a switching assembly mounted on the cake maker body. The valve stem has a drive end extending out of the liquid outlet chamber. The switching assembly is drivenly connected to the drive end, allowing the valve core to switch back and forth between the first position, the second position, and the third position.

[0020] In one embodiment, the switch assembly includes a rotating shaft body and blades connected to the rotating shaft body, the blades being used to abut against the drive end;

[0021] The pancake maker body is provided with a switch drive shaft, and the rotating shaft body is rotatably mounted on the switch drive shaft. A first elastic element is provided between the rotating shaft body and the pancake maker body, so that the rotating shaft body can move along its own axis.

[0022] In one embodiment, the rotating shaft body includes a first column, a second column, and a third column connected sequentially from top to bottom. The blade is connected to the outer periphery of the first column. The second column protrudes laterally from the first column and the third column. The first elastic element is sleeved on the outer periphery of the third column.

[0023] In one embodiment, a second elastic element is provided on the side of the valve stem away from the drive end, and a positioning post protrudes from the liquid inlet housing in the liquid inlet chamber, with the second elastic element sleeved on the positioning post;

[0024] Alternatively, a second elastic element is provided on the side of the valve stem away from the drive end, and a positioning post protrudes from the liquid inlet housing within the liquid inlet chamber. The positioning post has a receiving groove, and the second elastic element is disposed within the receiving groove.

[0025] In one embodiment, the liquid inlet housing further includes a connecting pipe and an adjusting member extending into the connecting pipe, wherein an air inlet gap communicating with the metering chamber is formed between the connecting pipe and the adjusting member, and the air inlet gap is in communication with the outside air.

[0026] In one embodiment, the liquid inlet housing has a connecting tube, one end of which is connected to the metering chamber and the other end is connected to the outside air.

[0027] The technical solution of this invention employs a cake-making machine with a quantitative liquid dispensing function, comprising a cake-making machine body and a liquid inlet mechanism. The liquid inlet mechanism is disposed in the cake-making machine body and includes a liquid inlet housing and a valve core. The valve core is disposed in the liquid inlet housing, which has a storage chamber and a quantitative chamber. The quantitative chamber has an inlet and an outlet, and the inlet is connected to the storage chamber. The valve core is used to open the inlet and close the outlet, and to close the inlet and open the outlet. With this configuration, when the valve core opens the inlet and closes the outlet, water or oil from the storage chamber continuously flows into the quantitative chamber until it is full. When a quantitative amount of water or oil needs to be dispensed, the valve core is driven to close the inlet and open the outlet, allowing all the water or oil to flow out. This ensures consistent water or oil dispensing each time, achieving quantitative water and oil dispensing and improving cake-making quality. Attached Figure Description

[0039] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0041] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0042] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, if the word "and / or" appears throughout the text, it means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0043] In recent years, the popularity of food cooking appliances has been increasing, and many fully automatic cooking appliances with different uses have appeared on the market. For example, automatic pancake makers can automate the entire pancake-making process. Users only need to prepare ingredients such as flour and water, and the automatic pancake maker can automatically perform processes such as feeding, kneading, pressing, and heating to make fresh and delicious pancakes.

[0044] In the operation of an automatic pancake-making machine, flour is first automatically dispensed from the flour cup and water from the water cup via a feeding mechanism. The flour and water are then mixed and kneaded into dough by a dough-kneading mechanism, which then conveys the dough to a pressing and baking mechanism. Finally, the pressing and baking mechanism flattens the dough while simultaneously heating it to form a pancake. However, existing automatic pancake-making machines have difficulty in precisely metering the water or oil inlet mechanisms. During the pancake-making process, the ratio of water or oil in the dough cannot be accurately controlled, resulting in pancakes of unsatisfactory quality.

[0045] Please see Figures 1 to 8 This invention proposes a cake-making machine with a quantitative liquid dispensing function.

[0046] The cake maker with quantitative liquid dispensing function includes a cake maker body 100 and a liquid inlet mechanism. The liquid inlet mechanism is disposed in the cake maker body 100 and includes a liquid inlet housing 240 and a valve core. The valve core is disposed in the liquid inlet housing 240. The liquid inlet housing 240 has a liquid storage chamber 241 and a quantitative chamber. The quantitative chamber has a liquid inlet 211 and a liquid outlet 231. The liquid inlet 211 is connected to the liquid storage chamber 241. The valve core is used to open the liquid inlet 211 and close the liquid outlet 231, and to close the liquid inlet 211 and open the liquid outlet 231.

[0047] Specifically, the liquid storage tank 241 has an upward-facing opening for storing liquid raw materials used to make the dough, such as water or oil. The following description focuses on the water inlet mechanism 200. The liquid storage tank 241 is exposed, allowing for periodic addition of water to maintain the required storage level. The valve core can open or close the inlet 211 and outlet 231 in various ways, as long as it can simultaneously open the inlet 211 and close the outlet 231, or simultaneously close the inlet 211 and open the outlet 231. When the valve core opens the inlet 211 and closes the outlet 231, the liquid storage tank 241 is connected to the inlet 211, and water continuously flows into the metering tank until it is full. When a specific amount of water needs to be added, the valve core is driven to close the inlet 211 and open the outlet 231, allowing all the water to flow out, with a consistent outflow each time. The oil inlet mechanism 300 works similarly. This setting ensures that the amount of water and oil added each time is consistent, achieving quantitative water and oil intake and improving the quality of cake making.

[0048] Please see Figures 1 to 3 or Figures 4 to 6 Furthermore, in one embodiment, the valve core is movably disposed within the metering chamber, giving the valve core a first position and a second position. In the first position, the valve core opens the inlet 211 and closes the outlet 231; in the second position, the valve core closes the inlet 211 and opens the outlet 231. By driving the valve core to move, it can switch between two positions: one where the inlet 211 is open and the outlet 231 is closed, and the other where the inlet 211 is closed and the outlet 231 is open. This ensures all water flows out, with the water and oil output being consistent each time, improving the cake-making quality.

[0049] Please see Figures 1 to 3 or Figures 4 to 6In a preferred embodiment, the valve core further has a third position, in which the valve core closes the liquid inlet 211 and the liquid outlet 231. It is understood that the cake-making machine of the present invention has three states: liquid inlet 211 open, liquid outlet 231 closed; liquid inlet 211 closed, liquid outlet 231 closed; and liquid inlet 211 closed, liquid outlet 231 open. The following description uses the water inlet mechanism 200 as the liquid inlet mechanism. Initially, the liquid inlet mechanism is in the open state of inlet 211 and closed state of outlet 231. Liquid continuously flows into the metering chamber from storage tank 241 but cannot flow out of outlet 231. Then, the valve core is driven to close inlet 211 and outlet 231, and the water volume in the metering chamber remains constant. When the valve core is driven again to open outlet 231 and close inlet 211, all the water on the right side of the first sealing plug 610 flows out from outlet 231. The water volume is consistent each time, achieving metered water intake. With this setting, the water volume in the metering chamber can be adjusted by driving the valve core to switch between the three states, achieving metered liquid intake and improving cake quality.

[0050] Please see Figures 1 to 3 or Figures 4 to 6 Further, in one embodiment, the valve core includes a first sealing plug 610, a second sealing plug 620, and a valve stem 630. Both the first sealing plug 610 and the second sealing plug 620 are sleeved on the outer periphery of the valve stem 630. The first sealing plug 610 is used to open or close the liquid inlet 211, and the second sealing plug 620 is used to open or close the liquid outlet 231. It can be understood that when the valve core is in the first position, liquid enters through the liquid inlet 211, and the second sealing plug 620 seals the liquid outlet 231. When the valve core is in the second position, the first sealing plug 610 seals the liquid inlet 211, and liquid exits through the liquid outlet 230. When the valve core is in the third position, the first sealing plug 610 seals the liquid inlet 211, and the second sealing plug 620 seals the liquid outlet 231. To ensure that the inlet 211 and outlet 231 can be closed simultaneously, in this embodiment, the distance between the first sealing plug 610 and the second sealing plug 620 is greater than the length of the metering chamber 220. To ensure a sealing effect, in a preferred embodiment, both the first sealing plug 610 and the second sealing plug 620 have sealing rings on their outer peripheries. Through the interference fit of the sealing rings, the sealing effect between the first sealing plug 610 and the inlet chamber 210, and the sealing effect between the second sealing plug 620 and the outlet chamber 230, can be ensured, thus enabling the switching of the three states of the cake maker.

[0051] Please see Figures 1 to 3 or Figures 4 to 6Furthermore, in one embodiment, the metering chamber includes an inlet chamber 210, a metering chamber 220, and an outlet chamber 230 connected in sequence. The inlet chamber 210 has an inlet port 211, and the outlet chamber 230 has an outlet port 231. An inlet gap may be formed between the outer periphery of the first sealing plug 610 and the second sealing plug 620 and the inner wall of the metering chamber 220. When the first sealing plug 610 is located in the inlet chamber 210, the first sealing plug 610 blocks the inlet port 211 from the metering chamber 220. When the second sealing plug 620 is located in the outlet chamber 230, the second sealing plug 620 blocks the outlet port 231 from the metering chamber 220. It is understood that when the valve core is in the first position, liquid enters the inlet chamber 210, and an inlet gap is formed between the first sealing plug 610 and the metering chamber 220, while the second sealing plug 620 seals the outlet chamber 230. When the valve core is in the second position, the first sealing plug 610 seals the inlet chamber 210, and an outlet gap is formed between the second sealing plug 620 and the metering chamber 220, allowing liquid to exit from the outlet chamber 230. The inlet chamber 210, metering chamber 220, and outlet chamber 230 can be cylindrical, and their cross-sections can be rectangular, circular, elliptical, polygonal, or irregular, etc., without specific limitations. In a preferred embodiment, the inlet chamber 210, the metering chamber 220, and the outlet chamber 230 are all cylindrical, with the diameter of the metering chamber 220 being larger than the diameters of the inlet chamber 210 and the outlet chamber 230. Initially, the liquid inlet mechanism is in the state where the liquid inlet chamber 210 is open and the liquid outlet chamber 230 is closed. The liquid storage tank 241 continuously flows into the liquid inlet chamber 210 and the metering chamber 220 but cannot flow out of the liquid outlet chamber 230. Then, the valve core is driven to close the liquid inlet chamber 210 and the liquid outlet chamber 230. At this time, the water volume in the metering chamber remains constant. When the valve core is driven again to open the liquid outlet chamber 230 and close the liquid inlet chamber 210, all the water on the right side of the first sealing plug 610 flows out from the metering chamber 220 and the liquid outlet chamber 230. The water volume is consistent each time, thus achieving metered water inlet.

[0052] Please see Figure 3 or Figure 6 To reduce the resistance of the first sealing plug 610 transitioning from the metering chamber 220 to the inlet chamber 210 and the resistance of the second sealing plug 620 transitioning from the metering chamber 220 to the outlet chamber 230, in one embodiment, a first transition section 221 is formed between the inlet chamber 210 and the metering chamber 220, and a second transition section 222 is formed between the metering chamber 220 and the outlet chamber 230. Both the first transition section 221 and the second transition section 222 are chamfered. Taking the first sealing plug 610 as an example, compared to a right-angle transition, the chamfered design allows the first sealing plug 610 to slide more smoothly into the inlet chamber 210, reducing resistance along the way.

[0053] Please see Figure 2or Figure 5 In one embodiment, the cake maker further includes a switch assembly 500, which is mounted on the cake maker body 100. The valve stem 630 has a drive end 631 extending from the liquid outlet chamber 230. The switch assembly 500 is driven by the drive end 631, allowing the valve core to move back and forth between the first position, the second position, and the third position. It is understood that the switch assembly 500 can be manually driven or driven by a motor, etc. Simply moving the valve core along its length via the switch assembly 500 switches the sealing positions of the first sealing plug 610 and the second sealing plug 620.

[0054] Please see Figure 2 , Figure 5 , Figure 7 In one embodiment, the switch assembly 500 includes a rotating shaft body 520 and a blade 510 connected to the rotating shaft body 520. The blade 510 is used to abut against the drive end 631. A switch drive shaft is provided on the cake maker body 100. The rotating shaft body 520 is rotatably mounted on the switch drive shaft. A first elastic element 530 is provided between the rotating shaft body 520 and the cake maker body 100, allowing the rotating shaft body 520 to move along its own axis. Specifically, when installing the water tank of the water inlet mechanism 200 or the oil tank of the oil inlet mechanism 300, it is necessary to prevent the valve core from being directly in the liquid outlet position, i.e., the third position. For example, when the blade 510 abuts against the valve core to the leftmost position, the first sealing plug 610 seals the liquid inlet chamber 210, but the second sealing plug 620 is located in the metering chamber 220 and does not seal the liquid outlet chamber 230, thus causing leakage. Therefore, when actually installing the water tank of the water inlet mechanism 200 or the oil tank of the oil inlet mechanism 300, the drive end 631 of the valve core needs to be placed on the top surface of the blade of the switch assembly 500, pressing the switch assembly 500 downward. When it is needed to work, the drive end 631 of the switch assembly 500 is disengaged from the end face of the switch assembly 500 after the switch assembly 500 is rotated to the appropriate position. Under the action of the first elastic element 530, the switch assembly 500 springs up, and only then can the blade 510 of the switch assembly 500 abut against the valve core to start the operation. In addition, the setting of the first elastic element 530 can also prevent the valve core from being misaligned. For example, during the long-term axial movement of the valve core, after the valve core has been used a certain number of times, the valve core will switch back and forth between the open and closed liquid inlet mechanism positions, and the valve core will inevitably be misaligned. When the valve core presses against the switch assembly 500 above it, the first elastic element 530 deforms and compresses, and the switch assembly 500 is reset upward by the elastic force of the first elastic element 530, so that the blade 510 of the switch assembly 500 can abut against the valve core to start the operation.

[0055] Continue reading Figure 2 , Figure 5 , Figure 7 In one embodiment, the rotating shaft body 520 includes a first column 521, a second column 522, and a third column 523 connected sequentially from top to bottom. The blade 510 is connected to the outer periphery of the first column 521, and the second column 522 protrudes laterally from the first column 521 and the third column 523. The first elastic element 530 is sleeved on the outer periphery of the third column 523. Specifically, to adapt to circular rotation, in one embodiment, the first column 521, the second column 522, and the third column 523 are all cylindrical, and the diameter of the second column 522 is larger than that of the first column 521 and the third column 523.

[0056] Please see Figures 1 to 3 or Figures 4 to 6 In one embodiment, a second elastic element 242 is provided on the side of the valve stem 630 away from the drive end 631, and a positioning post 243 protrudes from the liquid inlet housing 240 within the metering chamber. The second elastic element 242 is sleeved on the positioning post 243. It is understood that the second elastic element 242 can be rubber, a spring, etc., as long as it has sufficient elasticity to allow the drive end 631 to automatically reset the valve stem 630. In this embodiment, the second elastic element 242 is a spring. The positioning post 243 is used to position the second elastic element 242. When the water inlet mechanism 200 needs to be opened, the drive linkage shaft rotates counterclockwise, the drive end 631 is pushed, and the second elastic element 242 at the other end of the drive end 631 is compressed and elastically deformed, causing the drive end 631 to move to the left and open the water inlet mechanism 200; when the water inlet mechanism 200 needs to be closed, the drive linkage shaft rotates clockwise, the second elastic element 242 at the other end of the drive end 631 is elastically released, and the drive end 631 is automatically reset by the elastic force of the second elastic element 242 and moves to the right to close the water inlet mechanism 200. In another embodiment, the valve stem 630 is provided with a second elastic element 242 on the side away from the drive end 631, and the liquid inlet housing 240 is provided with a positioning post 243 protruding in the metering chamber. The positioning post 243 has a receiving groove, and the second elastic element 242 is disposed in the receiving groove.

[0057] Please see Figure 1 or Figure 4In one embodiment, the liquid inlet housing 240 further includes a connecting pipe 110 and an adjusting member 120 extending into the connecting pipe 110. An air inlet gap 130 communicating with the metering chamber is formed between the connecting pipe 110 and the adjusting member 120, and the air inlet gap 130 is in communication with the external air. The air inlet gap 130 helps to balance the pressure difference within the metering chamber 220, allowing the liquid in the metering chamber 220 to be discharged as much as possible, reducing the amount of liquid remaining in the metering chamber 220, thereby improving the accuracy of the metering liquid intake of the liquid inlet mechanism. In this embodiment, one end of the connecting pipe 110 is connected to the metering chamber 220, and the other end is connected to the external air. The connecting pipe 110 and the adjusting member 120 cooperate to form a relatively small liquid inlet gap 130, simplifying the manufacturing process. Furthermore, since the connecting pipe 110 communicates with the metering chamber 220, the amount of liquid fed into the liquid inlet mechanism can be adjusted by manually adjusting the axial position of the adjusting member 120 within the connecting pipe 110, improving the versatility of the liquid inlet mechanism.

[0058] The liquid inlet mechanism can be either a water inlet mechanism 200 or an oil inlet mechanism 300. The pancake maker of the present invention with a quantitative liquid dispensing function can include both the water inlet mechanism 200 and the oil inlet mechanism 300 of all the above embodiments, or only the water inlet mechanism 200 of all the above embodiments, or only the oil inlet mechanism 300 of all the above embodiments. It should be noted that the pancake maker has an automatic pancake-making function. This function requires the water inlet mechanism 200, the oil inlet mechanism 300, and the flour inlet mechanism 400 to supply water, oil, and flour to the dough mixing mechanism. The dough mixing mechanism then evenly mixes the water, oil, and flour and stirs them into a dough. After the dough is formed by the dough mixing mechanism, the pancake pressing and baking mechanism presses the dough into pancakes using a baking pan. Once the pancakes are pressed to a suitable thickness, the baking pan begins to heat and bake the pancakes until they are cooked.

[0059] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
