AI Technical Summary
Existing cooking equipment with steaming function is prone to siphoning in its water circuit structure, which causes water to flow out of the tank continuously. Traditional solutions are costly and have the risk of failure.
Design a water circuit structure that, by setting a T-joint and a third water pipe, places the inlet of the return water circuit higher than the outlet, thus preventing siphoning. This only requires adding a T-joint and a third water pipe, making it cost-effective and less prone to failure.
It effectively prevents siphoning, reduces costs, and does not fail over time, thus improving the reliability of the water system structure.

[0028] Please refer to Figure 1 and Figure 2 , the present application first provides a waterway structure arranged outside the inner container 100, comprising a water tank 10, a waterway assembly 20 and a water pump 30, the water tank 10 has a water outlet 13a and a backwater outlet 12a;
[0029] The waterway assembly 20 comprises a first water pipe 21, a second water pipe 22, a three-way joint 23, a third water pipe 24 and a fourth water pipe 25, both ends of the first water pipe 21 are respectively communicated with the water outlet 13a and the inlet of the water pump 30, both ends of the second water pipe 22 are respectively communicated with the outlet of the water pump 30 and the three-way joint 23, both ends of the third water pipe 24 are respectively communicated with the three-way joint 23 and the backwater outlet 12a, both ends of the fourth water pipe 25 are respectively communicated with the three-way joint 23 and the inner container 100; the three-way joint 23 is located on the upper side of the backwater outlet 12a.
[0030] In the present application, by arranging the three-way joint 23 and the third water pipe 24, the third water pipe 24 is used as a backwater waterway for backwater, and by arranging the three-way joint 23 higher than the backwater outlet 12a, the water inlet position of the backwater waterway is higher than the water outlet position, thereby fundamentally preventing the occurrence of siphon phenomenon.
[0031] Compared with the traditional scheme of adding an electromagnetic valve, the present application only needs to add a backwater waterway, i.e. the three-way joint 23 and the third water pipe 24, the cost is controllable, and since the present application solves the siphon problem from the principle level, it will not fail with long-term use, and is more reliable.
[0032] Specifically, the connecting position of the third water pipe 24 and the three-way joint 23 is the water inlet position of the backwater waterway, and the backwater outlet 12a is the water outlet position of the backwater waterway. By arranging the three-way joint 23 on the upper side of the water tank 10, the water inlet position of the backwater waterway is higher than the water outlet position, thereby achieving the effect of preventing siphon.
[0033] More specifically, the water flow path of the waterway structure of the present application is as follows,
[0034] The water outlet waterway: the water outlet 13a--the first water pipe 21--the water pump 30--the second water pipe 22--the three-way joint 23--the fourth water pipe 25--the inner container 100;
[0035] The backwater waterway: the three-way joint 23--the third water pipe 24--the backwater outlet 12a.
[0036] In some embodiments, the aperture of the backwater outlet 12a is smaller than that of the water outlet 13a, so as to increase the difficulty of backwater through the third water pipe 24 and reduce the backwater amount, while ensuring the effect of preventing siphon and reducing the influence on the water outlet amount of the fourth water pipe 25 as much as possible.
[0037] In some embodiments, the aperture of the backwater outlet 12a ranges from 1 mm to 2 mm, and the aperture of the water outlet 13a ranges from 2.5 mm to 4.5 mm.
[0038] Preferably, the aperture of the backwater outlet 12a is 1.5 mm, and the aperture of the water outlet 13a is 3.5 mm.
[0039] Of course, in other embodiments, the shape and area of the backwater outlet 12a and the water outlet 13a can also be adjusted according to actual conditions, as long as the area of the backwater outlet 12a is always smaller than that of the water outlet 13a, which will not be further limited herein.
[0040] Please refer to Figure 2 and Figure 3 In some embodiments, the water tank 10 is provided with an interface plate 11, the interface plate 11 is provided with a backwater interface 12 and a water outlet interface 13, one end of the backwater interface 12 is the backwater outlet 12a, and the other end penetrates the top wall of the water tank 10 to the inside of the water tank 10, one end of the water outlet interface 13 is the water outlet 13a, and the other end penetrates the side wall of the water tank 10 and extends to the inside of the water tank 10.
[0041] In some embodiments, the backwater outlet 12a is located above the water outlet 13a, and the height of the backwater outlet 12a is increased as much as possible to increase the difficulty of backwater and reduce the backwater amount.
[0042] In some embodiments, the other end of the water return interface 12 penetrates the top wall of the water tank 10 to the inner top of the water tank 10, and the other end of the water outlet interface 13 penetrates the side wall of the water tank 10 and extends to the inner bottom of the water tank 10, so as to ensure that the water in the water tank 10 can be pumped out through the water outlet interface 13 as much as possible, reduce the residual water in the water tank 10, and increase the actual available water amount of the water tank 10 under the same volume.
[0043] Please refer to Figure 2 and Figure 3 In some embodiments, the water outlet interface 13 is L-shaped at the outer side of the water tank 10, the water outlet 13a is downwardly formed, and the water pump 30 is located at the lower side of the water outlet 13a.
[0044] In this way, the water in the water tank 10 is pumped downwardly through the water outlet 13a, so as to reduce the power requirement of the water pump 30.
[0045] Please refer to Figure 2 and Figure 3 In some embodiments, the third water pipe 24 includes an ascending section 24a and a descending section 24b, one end of the ascending section 24a is in communication with the three-way joint 23, the other end of the ascending section 24a extends upwardly and is in communication with the descending section 24b, and the other end of the descending section 24b is in communication with the water return port 12a.
[0046] By designing the ascending section 24a higher than the three-way joint 23, the difficulty of water flow further flowing along the ascending section 24a from the three-way joint 23 is increased, that is, the difficulty of water return is increased, so that most of the water flow flows into the inner container 100 along the fourth water pipe 25 at the three-way joint 23, thereby further reducing the water return amount.
[0047] The second aspect of the present application provides a cooking device comprising the above waterway structure.
[0048] The technical features of the above embodiments can be combined arbitrarily, and in order to make the description simple, all possible combinations of the technical features in the above embodiments are not described, however, as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.
[0049] The above embodiments only express several implementation manners of the present application, the description is more specific and detailed, but it should not be understood as the limitation of the scope of the present application. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application patent should be subject to the appended claims.
