Description

Technical Field

[0001] The utility model relates to the technical field of stewing machines, in particular to an automatic stewing machine. Background Art

[0002] In the related technology, with the improvement of people's living standards, bird's nest machines for stewing bird's nests are widely used in households, and their market prospects are unanimously optimistic.

[0003] However, the current bird's nest machine generally adopts the method of water-bath stewing or air-bath heating, which uses water or air to conduct heat to achieve the purpose of stewing the bird's nest, and the stewing time is relatively long.

[0004] In addition, the water-bathed stewing process uses water to conduct heat in the stewing pot, and the bird's nest has no way to combine with the water vapor. The bird's nest tastes average, and the user experience is not good.

[0005] In addition, the bird's nest machine uses a double-boiled stewing method that requires manual water addition, and the ratio of the amount of water added to the grams of bird's nest is inaccurate, so the taste of the bird's nest stewed by different users varies greatly.

[0006] Therefore, it is necessary to improve the existing technology. Utility Model Content

[0056] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific embodiments of the present invention or equivalent replacements of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed in the present invention.

[0062] The water outlet channel is used to discharge the water in the stew pot 21 out of the automatic stewing machine or store it in the water storage box 41 in the housing assembly 1;

[0063] The steam in the stew pot 22 can enter the condensation water path through the through hole 230 and the water adding mechanism 3 . The condensation water path is used to cool the steam into condensed water and store it in the water storage box 41 in the housing assembly 1 .

[0064] The automatic stewing machine provided in this embodiment is beneficial to improving heating efficiency and enhancing user experience.

[0065] The automatic stewing machine provided in this embodiment employs both internal and external heating. The stew pot assembly 2 utilizes a heating plate to heat the water in the stew pot, allowing the water to conduct heat to heat the bird's nest or other food in the stew pot, similar to existing double-boiler systems. Internal heating involves spraying high-temperature steam into the stew pot. When the steam heats the water, it accelerates the rise in water temperature.

[0066] High temperature steam stewed bird's nest has the following uses:

[0067] 1. Speed up the rise of water temperature in the stewing pot, thereby reducing the time of stewing bird's nest.

[0068] 2. The high-temperature steam is ejected at a certain speed, which can quickly combine the bird's nest with the water vapor, making the bird's nest taste better when stewed.

[0069] The automatic stewing machine provided in this embodiment can use an intelligent algorithm. Users can select different bird's nest types and input the number of grams of dry bird's nest. The intelligent automatic stewing machine automatically adds a fixed amount of water to the stewing pot. At the same time, it automatically adds a fixed amount of room temperature water or high temperature water to the stew pot outside the bird's nest stewing pot to ensure the best taste of the bird's nest.

[0070] In addition, the time can be set to automatically add water to the stewing pot to achieve the purpose of stewing bird's nests at a scheduled time.

[0071] After the bird's nest is stewed, the high-temperature water in the stew pot will be automatically pumped out, and the stew pot can automatically be filled with normal temperature water to speed up the cooling of the bird's nest in the stew pot.

[0072] After the bird's nest is stewed, the high-temperature water in the stew pot will be automatically pumped out. When pouring out the bird's nest, do not remove the stewing pot from the stew pot.

The fourth connecting pipe 108 is used to inject hot water or room temperature water or steam into the top of the stewing pot 22. Its structure is simple, and the water is heated by the steam generator 104 to become high-temperature hot water or high-temperature steam, and injected from the top of the stewing pot.

[0074] Furthermore, a water flow sensor 42 is provided on the first connecting pipe 101, and the water flow sensor 42 is used to detect the water inlet condition of the water inlet channel, ensuring that the steam generator 104 is started only after a stable water flow is ensured, thereby improving the reliability and safety of product use.

[0148] (2) Add water to the stewing pot from the top of the stewing pot, and add water to the stewing pot from the bottom of the stewing pot.

[0149] (3) The water temperature is controlled by the program to control the power of the steam generator and the flow of the electromagnetic pump. It can be divided into normal temperature water, specified temperature water and specified temperature steam.

[0150] (4) The amount of water added is controlled by the program to adjust the flow control of the electromagnetic pump or the coordinated flow meter.

[0151] (5) Drainage is sucked out from the bottom of the stew pot by a water pump. The direction of the sucked water is controlled by a second solenoid valve, which determines whether it is discharged to the outside of the automatic stew machine or into the water storage box inside the machine.
