[0021] The beneficial effects of the present invention are:

[0022] 1. This kind of kitchen appliance with fermentation and dough proofing functions draws out the air in the negative pressure suction cup through the air path system, so that the negative pressure suction cup can be tightly adsorbed on the countertop of the kitchen workbench, thereby stabilizing the kitchen appliance. After adjusting the angle of the proofing pot, the transmission shaft is locked by the locking assembly, which can further stabilize the proofing pot, and can effectively solve the problem of needing to hold the proofing pot with hands when taking out the dough, so that the user can take out the dough more effortlessly.

[0023] 2. This kitchen appliance with fermentation and dough proofing functions drives the proofing pot away from the containing plate through the lifting component. The lifting component and the transmission component are used together to drive the transmission shaft, so that the transmission part rotates with the movable block, thereby changing the angle of the proofing pot, so that the mouth of the proofing pot can be tilted downward, so that the user can take out the dough more conveniently.

[0024] 3. For this kind of kitchen appliance with fermentation and dough proofing functions, the locking cap is rotated to rotate and move in the direction away from the dynamic bracket, and the matching plate is pushed by the locking cap to move the sliding rod outward. The locking plate is driven by the sliding rod to insert the locking column into the corresponding locking hole to lock the transmission shaft. This can effectively prevent the transmission shaft from rotating on its own, which can not only stabilize the proofing pot, but also avoid wear of the transmission belt caused by the rotation of the transmission shaft.

[0025] 4. This kind of kitchen appliance with fermentation and dough proofing functions, after connecting the air pump, the circulation pipeline and the hot air duct, allows the gas to enter the hot air duct from the circulation pipeline through the air pump, so that the gas circulates among the air pump, the circulation pipeline and the hot air duct, and the gas exchanges heat with the electric heating wire when passing through the electric heating wire, and is heated by the circulating hot air. Compared with direct heating with the electric heating wire, the temperature rise is more stable, which is more conducive to dough proofing and fermentation.

[0026] 5. This kind of kitchen appliance with fermentation and dough proofing functions can quickly assemble the accommodating plate on the base through the cooperation of the mounting convex edge and the mounting ring groove, which is conducive to the later maintenance of the equipment.

DETAILED DESCRIPTION

[0041] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0042] Example: Figure 1-5 As shown, the present invention is a kitchen appliance with fermentation and dough proofing functions, comprising a base 1, a receiving tray 12 is provided on the top of the base 1, a hot air duct 122 is provided in the receiving tray 12, four mounting grooves formed by extension parts 13 are provided at the bottom of the base 1, the four extension parts 13 are distributed in a rectangular shape and extend into the base 1, a connecting pipeline 14 is further provided in the base 1, and both sides of the base 1 are connected with supporting square tubes 11;

[0043] A proofing pot 2 that can be placed in the receiving tray 12;

[0044] A negative pressure suction cup 6 is arranged in the mounting groove, and a ventilation interface of the negative pressure suction cup 6 is connected to the connecting pipeline 14;

[0045] The air path system provided in the base 1 can make the hot air circulate in the hot air pipe 122 or make the negative pressure suction cup 6 form a negative pressure area;

[0046] The driving unit 7 for driving the proofing pot 2 includes a movable block 71 arranged on the top of the supporting square tube 11 and a sliding bracket 73 slidably arranged in the supporting square tube 11. A transmission member 72 is provided at the bottom of the movable block 71, and a transmission rod 77 rotatably connected to the sliding bracket 73 is provided through the transmission member 72.

[0047] Specifically, a through groove for accommodating the locking assembly and for installing the rack 75 is opened on the inner wall of the supporting square tube 11.

[0048] Among them, Figure 8-12As shown, the transmission rod 77 includes a transmission shaft 771 that passes through the upper part of the sliding bracket 73 and a locking assembly for preventing the transmission shaft 771 from rotating. The transmission shaft 771 is rotatably connected to the sliding bracket 73 through a bearing. A sliding hole is provided at the other end of the transmission shaft 771, and a matching cavity is connected to one end of the sliding hole. A plurality of locking holes 777 that are connected to the matching cavity are also provided outside the sliding hole, and a positioning column 776 is provided in the matching cavity. When the transmission shaft 771 is rotated by the rotating shaft 76, the positioning column 776 drives the locking plate 775 to rotate in the matching cavity, which is conducive to aligning the locking column with the locking hole 777; when the matching plate 773 is pushed by the locking cap 774, the positioning column 776 slides and cooperates with the U-shaped hole to play a guiding role.

[0049] In this embodiment, the locking assembly includes a locking plate 775 slidably arranged in the matching cavity, a fixing sleeve 772 rotatably matched with the transmission shaft 771 and installed on the sliding bracket 73 by bolts, and a locking cap 774 screwed with the fixing sleeve 772. The locking plate 775 is provided with a U-shaped hole that matches with the positioning column 776. A sliding rod 778 that slidably matches with the sliding hole is provided on one side of the locking plate 775. At least one locking column that can be plugged into the locking hole 777 is also provided on the outer side of the sliding rod 778. A matching plate 773 connected to the sliding rod 778 is also provided on one side of the locking cap 774, so that it is pushed by the locking cap 774. The mating plate 773 can drive the sliding rod 778 to move outward. In the present embodiment, two locking columns arranged opposite to each other are provided, or only one may be provided. One end of the fixing sleeve 772 is closed, and the other end is provided with a mounting ring plate, and the mounting ring plate is used to connect with the sliding bracket 73. The closed end of the fixing sleeve 772 is provided with a through hole coaxial with the sliding hole, and the through hole is slidably matched with the sliding rod 778. The fixing sleeve 772 can be directly sleeved on the outside of the transmission shaft 771, or it can be connected through a bearing. However, compared with the bearing connection, the fixing sleeve 772 is directly sleeved on the outside of the transmission shaft 771, which can be easily disassembled.

[0050] The locking cap 774 is rotated to rotate and move in a direction away from the sliding bracket 73, and the matching plate 773 is pushed by the locking cap 774 to move the sliding rod 778 outward, and the locking plate 775 is driven by the sliding rod 778 until the locking column is inserted into the corresponding locking hole 777, so that the transmission shaft 771 can be locked, which can effectively prevent the transmission shaft 771 from rotating (for example, due to the gravity of the tilted proofing pot 2), thereby stabilizing the proofing pot 2 and preventing the transmission belt from being worn due to the rotation of the transmission shaft 771;

[0051] The locking cap 774 is rotated back to its original position, and then the matching plate 773 is also pushed back to its original position, so that the locking column is disengaged from the corresponding locking hole 777, and the locking of the transmission shaft 771 can be released.

[0052] In this embodiment, an avoidance hole through which the sliding rod 778 can pass is formed in the locking cap 774. The inner wall of the avoidance hole does not contact the outer wall of the sliding rod 778, and the diameter of the avoidance hole is larger than the diameter of the sliding rod 778. Therefore, when the sliding rod 778 rotates, it will not drive the locking cap 774 to rotate together. When the locking cap 774 is rotated, the sliding rod 778 will not rotate with the locking cap 774 either.

[0053] Among them, as Figure 5 and Figure 6 shown, the driving unit 7 further includes a lifting component and a transmission component for driving the sliding bracket 73 to move up and down. The sliding bracket 73 is fixedly connected to the moving body of the lifting component through a C-shaped connecting piece. The transmission component is composed of a rack 75 installed on the upper part of the support square tube 11 and a rotating shaft 76 arranged below the transmission rod 77. The rotating shaft 76 is传动连接 with the transmission shaft 771 through a first transmission belt, so that the rotating shaft 76 can drive the transmission shaft 771 to rotate through the transmission belt. One end of the rotating shaft 76 is rotationally connected to the sliding bracket 73, and a gear 74 that can mesh with the rack 75 is sleeved and fixed at the other end.

[0054] The lifting component drives the sliding bracket 73 to move upward. The sliding bracket 73 drives the proofing pot 2 to move upward through the movable block 71, so that the proofing pot 2 leaves the receiving tray 12. Then the lifting component continues to drive the sliding bracket 73 to move upward, so that the gear 74 meshes with the rack 75 for transmission. The gear 74 drives the rotating shaft 76, and the rotating shaft 76 drives the transmission shaft 771 through the first transmission belt, so that the transmission member 72 drives the movable block 71 to rotate, thereby changing the angle of the proofing pot 2, so that the mouth of the proofing pot 2 can be inclined downward, making it more convenient for the user to take out the dough.

[0055] In this embodiment, the lifting component is composed of a lifting motor installed at the bottom of the receiving tray 12 and a lifting lead screw located inside the sliding bracket 73. The bottom end of the lifting lead screw is rotationally connected to the base 1. A nut slider is sleeved outside the lifting lead screw, and the nut slider is the moving body connected to the C-shaped connecting piece. A driving rod is installed on the output shaft of the lifting motor, and the driving rod is传动连接 with the lifting lead screw through a second transmission belt. When the lifting motor drives the driving rod to rotate, the driving rod rotates the lifting lead screw through the second transmission belt, so that the nut slider can reciprocally move along the lifting lead screw. The nut slider (i.e., the moving body) will drive the sliding bracket 73 to move through the C-shaped connecting piece. In addition to the above technical solution, other implementation manners can also be adopted for the lifting component.

[0056] Among them, as Figure 1 shown, L-shaped connecting pieces 21 for connecting with the movable block 71 are symmetrically arranged on the outer wall of the proofing pot 2, so that the proofing pot 2 can be driven to change the angle through the movable block 71. The connection between the L-shaped connecting piece 21 and the movable block 71 is completed through bolts to complete the fixation of the proofing pot 2.

[0057] Among them, Figure 2 and Figure 7 As shown, the accommodating plate 12 is composed of a heat conductor for accommodating the proofing pot 2 and a heat-insulating plastic part arranged on the outside of the heat conductor, the heat-insulating plastic part is provided with a mounting flange 121 on the outside, and the hot air duct 122 is arranged between the heat conductor and the heat-insulating plastic part. The heat conductor is made of a material with good thermal conductivity, such as copper, which is conducive to conducting heat to the proofing pot 2; the heat-insulating plastic part plays a heat-insulating role, which is beneficial to the operation of the air pump 4, the motor and other components.

[0058] In this embodiment, a temperature sensor is also required to be provided on the receiving tray 12. The temperature sensor can be provided through the heat-insulating plastic part. The temperature sensor is electrically connected to the control unit. The temperature is detected by the temperature sensor, and the detection signal is transmitted to the control unit, which determines whether the temperature exceeds the set value.

[0059] Among them, Figure 2 and Figure 3 As shown, the top of the base 1 is provided with a mounting groove matching the mounting flange 121, and a control unit is also provided inside the base 1. Through the cooperation between the mounting flange 121 and the mounting groove, the accommodating plate 12 can be quickly assembled on the base 1, which is convenient for later maintenance of the equipment.

[0060] Specifically, the base 1 is also provided with two operating knobs electrically connected to the control unit for setting the temperature and heating time. In addition, the two operating knobs can also be replaced by a touch screen to set the temperature and heating time.

[0061] Among them, Figure 3 As shown, the air circuit system is composed of an air pump 4 arranged in the base 1 and electrically connected to the control unit, a circulation pipeline 5 connected to the hot air pipe 122 and a negative pressure air circuit 3 connected to the connecting pipeline 14. The air pump 4 is connected to the circulation pipeline 5 and the negative pressure air circuit 3 through pipelines. The circulation pipeline 5 and the negative pressure air circuit 3 are both provided with multiple three-way valves for switching the gas flow direction; the circulation pipeline 5 is used in conjunction with the air pump 4 to realize the functions of extracting air from the outside (an air filter can be added to filter the gas), circulating the hot air between the air pump 4, the circulation pipeline 5 and the hot air pipe 122, and discharging the hot air; the negative pressure air circuit 3 is used in conjunction with the air pump 4 to realize the functions of extracting air from the negative pressure suction cup 6 and inflating the negative pressure suction cup 6.

[0062] By switching the three-way valve, the air pump 4, the circulation pipeline 5 and the hot air pipe 122 are connected, and the gas enters the hot air pipe 122 from the circulation pipeline 5 through the air pump 4, so that the gas circulates among the air pump 4, the circulation pipeline 5 and the hot air pipe 122, and the gas exchanges heat with the electric heating wire when passing through the electric heating wire, and is heated by the circulating hot air. Compared with direct heating by the electric heating wire, the temperature rise is more stable, which is more conducive to the dough proofing and fermentation;

[0063] By switching the three-way valve, the air pump 4, the negative pressure air circuit 3, the connecting pipe 14 and the negative pressure suction cup 6 are connected, and the air in the negative pressure suction cup 6 is extracted by the air pump 4, so that the negative pressure suction cup 6 can be tightly adsorbed on the countertop of the kitchen workbench, thereby stabilizing the kitchen appliance, which can effectively solve the problem of needing to hold the proofing pot 2 by hand when taking out the dough.

[0064] In this embodiment, the connecting pipeline 14 includes connecting interfaces that are arranged through the extending portion 13 . The number of the connecting interfaces is set to four, and the four connecting interfaces are connected in series through connecting pipes.

[0065] Specifically, the air inlet of the hot air pipe 122 is provided with a heating wire, and the heating wire is electrically connected to the control unit, and heat is provided by the working heating wire.

[0066] During operation, the air pump 4, the circulation pipeline 5 and the hot air pipe 122 are connected by switching the three-way valve, and the gas enters the hot air pipe 122 from the circulation pipeline 5 through the air pump 4, so that the gas circulates among the air pump 4, the circulation pipeline 5 and the hot air pipe 122, and the gas exchanges heat with the electric heating wire when passing through the electric heating wire, and is heated by the circulating hot air. When the temperature reaches the set value, the dough is placed in the proofing pot 2, and the proofing pot 2 is covered with a pot lid or a plastic wrap. After the dough is proofed or fermented, the air pump 4, the negative pressure air circuit 3, the connecting pipeline 14 and the negative pressure suction cup 6 are connected by switching the three-way valve, and the air in the negative pressure suction cup 6 is extracted by the air pump 4, so that the negative pressure suction cup 6 can be tightly adsorbed on the kitchen The lifting assembly then drives the sliding bracket 73 to move upward, and the sliding bracket 73 drives the proofing pot 2 upward with the help of the movable block 71, so that the proofing pot 2 leaves the accommodating plate 12. Then the lifting assembly continues to drive the sliding bracket 73 upward, so that the gear 74 and the rack 75 are meshed for transmission, and the gear 74 drives the rotating shaft 76. The rotating shaft 76 drives the transmission shaft 771 with the transmission belt 1, so that the transmission member 72 rotates with the movable block 71 to change the angle of the proofing pot 2. After adjusting the angle of the proofing pot 2, the locking assembly is used to lock the transmission shaft 771, which can further stabilize the proofing pot 2, so that the user can take out the dough very conveniently.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
