Description

Technical Field

[0001] The present invention relates to the technical field of kitchen equipment, in particular to an electric steamer. Background Art

[0002] An electric steamer, also known as an electric steamer, is a kitchen appliance developed based on traditional wooden, aluminum, and bamboo steamers. It uses electric steam to directly steam a variety of foods. Electric steamers are primarily used in homes, restaurants, canteens, and hotels to steam or stew fish, shrimp, poultry, eggs, meat, and pasta. As living standards in my country improve, sales of electric steamers are also increasing.

[0003] The electric steamer can heat evenly and maintain a consistent temperature inside the steamer, so that the food is heated evenly and will not be undercooked. It also adopts a stacked food steamer design, which can cook multiple dishes at the same time, saving space and time, and can also be used to store food. For details, please refer to the applicant's Chinese patent application number CN202521760990.4 "Electric Steamer with Multi-Use Modes".

[0004] However, the existing electric steamer still has the following problems when in use:

[0005] First, when using an electric steamer, multiple foods are generally placed in multiple steaming trays and steamed together. However, since different foods take different amounts of time to steam, in order to avoid the loss of nutrients in the food due to excessive steaming time, the steaming trays need to be opened frequently to take out the food during steaming. This method is cumbersome and inconvenient to use the electric steamer.

[0006] Second, when using an electric steamer, the steaming time is generally set based on the working time of the steamer. However, the steaming time of some foods (such as crabs) is calculated from the time when the steam starts to rise. This makes the steaming time of the food inaccurate, thus affecting the steaming effect of the food.

[0007] Third, when the electric steamer is currently in use, the steam generated inside generally flows from bottom to top, causing the bottom of the food in the steamer to be heated, thereby causing the food to be heated unevenly and affecting the steaming effect of the food.

[0096] The working principle of this embodiment is as follows: when food needs to be steamed,

[0097] (1) Installation:

[0098] First, add appropriate amount of water into the pot body 12, then pull the first elastic positioning pin 114 to the right, insert the positioning block 217 of the first layer of steamer 2 into the corresponding first slide groove 112, and then drag the first layer of steamer 2 to the left until the first connecting block 218 is constrained under the first positioning hook 113, release the first elastic positioning pin 114, so that the second connecting block 219 is constrained under the first elastic positioning pin 114. At this time, the second connecting wheel 622 corresponding to the first layer of steamer 2 is engaged with the first connecting wheel 621, and the first layer of steamer 2 is fixed. Similarly, pull the second elastic positioning pin 216 of the first layer of steamer 2 to the right, insert the positioning block 217 of the second layer of steamer 2 into the second slide groove 21 of the first layer of steamer 2 4, and then drag the second layer of steamer 2 to the left until the first connecting block 218 is constrained under the second positioning hook 215 of the first layer of steamer 2, and loosen the second elastic positioning pin 216 of the first layer of steamer 2 so that the second connecting block 219 is constrained under the second elastic positioning pin 216. At this time, the second connecting wheel 622 corresponding to the second layer of steamer 2 is engaged with the third connecting wheel 623 corresponding to the first layer of steamer 2, thus completing the fixation of the second layer of steamer 2; similarly, fix the third layer of steamer 2 on the second layer of steamer 2; then cover the top cover 4 on the third layer of steamer 2 to complete the installation of the electric steamer. At this time, the drawers 22 on each layer of steamer 2 are extended outward under the elastic force of the first elastic member 24 and are in the open position;

[0099] (2) Timing:

[0100] First, place the food to be steamed on the steaming plate 23, then push the drawer 22 inward to put the food into the steamer body 21. During this process, the locking rod 252 moves backward. When the drawer 22 is fully pushed in, the front side wall of the drawer 22 will close the opening on the front side of the third steam chamber 211, and the locking pin 2521 on the locking rod 252 passes through the notch 2511 on the locking plate 251. Then turn the knob 511 to store energy for the clockwork timer 51 and adjust the timing time. During this process, the clockwork timer 51 drives the first gear 521 to rotate. Since the second gear 522 is engaged with the first gear 521, the second gear 522 is engaged with the first gear 521. 522 rotates accordingly, and since the third gear 523 is meshed with the second gear 522, the third gear 523 drives the locking plate 251 to rotate synchronously, so that the locking pin 2521 is staggered with the notch 2511 and constrained behind the locking plate 251, thereby the drawer 22 can overcome the elastic force of the first elastic member 24 and remain in the closed position. At the same time, the ratchet 532 rotates synchronously with the second gear 43, and due to the action of the pawl 481, the ratchet 532 cannot rotate. Thus, the timing of the food placement and steaming time is completed. The timing of each layer of the steamer 2 can be adjusted according to the type of food placed.

[0101] (3) Steaming:

[0102] The heating element 3 is started to heat the water in the pot body 12, causing the water to boil and generate steam. The steam in the first steam chamber 121 rises to the third steam chamber 211 of each steamer body 21 in turn, and heats the food through the steaming plate 23. At the same time, the water in the second steam chamber 122 also boils, and the generated steam rises to the second steam flow channel 212 of each steamer body 21 in turn, and enters the first connecting section 2131 of the corresponding connecting flow channel 213 through each second steam flow channel 212. The air pressure in the first connecting section 2131 continues to rise with the generation of steam. When the pressure difference between the first connecting section 2131 and the second connecting section 2132 reaches a set value, the pressure valve core 531 can overcome the elastic force of the second elastic member 535 under the action of the steam pressure and move upward, so that the plug 5311 releases the blockage of the entrance of the second connecting section 2132, thereby allowing the steam in the first connecting section 2131 to enter the second connecting section 2132. Finally, steam is blown into the third steam chamber 211 through the outlet end 2130, so that steam blows horizontally onto the food. At the same time, the ratchet 533 moves upward synchronously with the pressure valve core 47 and disengages from the ratchet 532, releasing the limiting relationship between the ratchet 532 and the ratchet 532. At this time, under the action of the clockwork timer 51, the knob 511 and the first gear 521 can be driven to rotate slowly. Under the transmission of the second gear 522 and the third gear 523, the locking plate 251 can be rotated slowly. When the clockwork timer 51 is reset, the locking pin 2521 is aligned with the notch 2511 and the limiting relationship with the locking plate 251 is released, so that the drawer 22 is moved forward to the open position under the elastic force of the first elastic member 24, so that the food can be automatically pushed out after steaming is completed, thereby preventing nutrient loss caused by excessive steaming time. At this time, the rear side wall of the drawer 22 will close the opening on the front side of the third steam chamber 211, preventing steam from leaking out and affecting the steaming of other food.

[0103] At the same time, when steam passes through the first steam flow channel 1221 of the second steam chamber 122, it can drive the steam wheel 61 to rotate, thereby driving the first connecting wheel 621 to rotate synchronously through the second rotating shaft 611. Since the second connecting wheel 622 and the first connecting wheel 621 or the third connecting wheel 623 are engaged, the first bevel gear 624 is driven to rotate. Since the second bevel gear 625 and the first bevel gear 624 are engaged, the conical roller 626 is driven to rotate. Since the conical ring 627 is tightly attached to the conical roller 626 at this time, the conical ring 627 is driven to rotate by friction, so that the steaming plate 23 drives the food to rotate, so that the food is heated more evenly until the steaming is completed.
