However, after the steaming oven has steamed the food, there is a problem that the residual water in the steam generator 21 needs to be cleaned, so as to avoid bacteria breeding, generating odor, and affecting the user experience. As shown in fig. 1 and 2, in this embodiment, the pipeline structure 1 further includes a drain pump 12, and the drain pump 12 can pump the condensed water in the steam generator 21 and the water-gas separator into the water tank 5 again, so that not only can the water be recycled, but also the generation of the odor can be avoided.

However, because the pipeline structures of water inlet and water outlet are mutually independent, the cost of the whole machine is high and the cost performance of the product is affected because more parts are used.

In the pipeline structure 1, the first water outlet 112 of the water inlet pump 11 and the second water inlet 121 of the drainage pump 12 are both communicated with the vertical section 161 of the second water pipe 16, the water inlet pump 11, the drainage pump 12, the water tank 5 and the water using device are connected through the first three-way pipe 13 and the second three-way pipe 14 and are arranged between the first water pipe 15 and the second water pipe 16, the water in the water tank 5 can be pumped into the horizontal section 162 by the water inlet pump 11 to supply water to the water using device, the water in the horizontal section 162 and the water pump in the water using device can be pumped into the water tank 5 by the drainage pump 12, the water supply to the water using device and the water pumping back to the water tank 5 can be completed through only one main pipeline, the common pipeline of water inlet and drainage of the water using device is realized, the multiplexing of the second water pipe 16 is realized, the pipeline structure 1 is simplified, the number of parts is reduced, and the cost of the whole machine is reduced. In the present embodiment, the horizontal segment 162 of the second water pipe 16 communicates with the bottom of the steam generator 21 and the bottom of the water vapor separation pipe 23 so that the water in the steam generator 21 and the water vapor separation pipe 23 can be entirely extracted when the steam generator 21 and the water vapor separation pipe 23 are drained.

As shown in fig. 1 and 2, the pipeline structure further includes a second tee 14, the second tee 14 is disposed on the vertical section 161, a third connection port of the second tee 14 is communicated with the first water outlet 112, and a flowing distance of water between the second tee 14 and the second water inlet 121 is 20% -40% of a length of the vertical section 161. The higher the height of the second tee 14, the longer the vertical section is multiplexed and the simpler the pipe structure 1, in this embodiment the flow distance of water between the second tee 14 and the second water inlet 121 may be 20%, 25%, 30%, 35% or 40% of the length of the vertical section 161.

In this embodiment, the pipeline structure further includes a first tee 13 and a first water pipe 15, three connectors of the first tee 13 are respectively connected to the first water inlet 111, the second water outlet 122 and the first water pipe 15, and the other end of the first water pipe 15 is connected to the water tank 5. The first tee 13 is utilized to connect the first water inlet 111 and the second water outlet 122, so that the pipeline structure 1 can be further simplified, the number of parts is reduced, and the cost is reduced.

Further, the cooking appliance further comprises a water level detector 4, the water level detector 4 is communicated with the horizontal segment 162 of the second water pipe 16, at this time, the water level detector 4, the steam generator 21 and the water-vapor separation pipe 23 form a communicating vessel, a water level sensor is arranged in the water level detector 4, and the water level in the water level detector 4 is detected through the water level sensor, so that the water level in the steam generator 21 and the water-vapor separation pipe 23 can be known.

In this embodiment, the water consumption device is lower than the water tank 5, the pipeline structure 1 further includes an anti-siphon assembly 17, one end of the anti-siphon assembly 17 is connected to the second tee 14, and the other end of the anti-siphon assembly 17 is connected to the first water outlet 112.

It will be appreciated that the amount of water pumped into the steam generator 2 is much greater than the amount of water pumped back into the water tank 5, so that the water tank 5 is at a higher level than the water usage device, facilitating the water supply from the water inlet pump 11 to the steam generator 2. The anti-siphon component 17 can prevent water in the water tank 5 from entering the steam generating device 2 under the siphon action when the water inlet pump 11 is closed.

Specifically, the anti-siphon assembly 17 includes a main pipe 171 and a secondary pipe 172 in communication, the secondary pipe 172 having a pipe diameter smaller than that of the main pipe 171, the secondary pipe 172 being in communication with the first water outlet 112, the main pipe 171 being in communication with the vertical section 161 of the second water pipe 16. Because the pipe diameter of the secondary pipe 172 is relatively small, when the water inlet pump 11 is started, the primary pipe 171 is not filled up when water enters the primary pipe 171 from the secondary pipe 172, so that the pressure between the water tank 5 and the steam generator 2 is balanced, and the occurrence of a siphon phenomenon is avoided.

The pipe diameter of the main pipe 171 is 1.5 to 2.5 times the pipe diameter of the sub pipe 172, and specifically, the pipe diameter of the main pipe 171 may be 1.5 times, 1.7 times, 1.9 times, 2.1 times, 2.3 times, and 2.5 times the pipe diameter of the sub pipe 172.

As shown in fig. 2 to 5, the sub-pipe 172 is inclined downward in a direction away from the main pipe 171. When the water inlet pump 11 is turned off, water is disconnected at the connection between the secondary pipe 172 and the main pipe 171, and the main pipe 171 is also prevented from being filled with water, so that the pressure between the water tank 5 and the steam generator 2 is balanced, and the occurrence of a siphon phenomenon is prevented.

Specifically, the connection position of the secondary pipe 172 and the primary pipe 171 is located at the side wall of the primary pipe 171. When water enters the main pipe 171 from the sub pipe 172, it is washed toward the side wall of the main pipe 171 and then flows downward, thereby reducing the flow rate of water entering the steam generator 2 and ensuring the stability of water flow.

In this embodiment, the drain pump 12 is a one-way pump, that is, even if the drain pump 12 is turned off, water in the water tank 5 does not enter the steam generator 2 through the drain pump 12, so the anti-siphon assembly 17 may not be disposed on the pipeline of the drain pump 12.

The foregoing is merely exemplary of the present utility model, and those skilled in the art should not be considered as limiting the utility model, since modifications may be made in the specific embodiments and application scope of the utility model in light of the teachings of the present utility model.
