Description

Technical Field

[0001] The utility model belongs to the technical field of kitchen appliances, and particularly relates to a cooking utensil provided with a siphon type water supply device. Background Art

[0002] Currently, some cooking appliances, such as air fryers, ovens, and steam ovens, have incorporated a water replenishment system into their bodies to prevent significant moisture loss during cooking, which can dry out or harden the food and result in a poor taste. These systems replenish water within the cooking cavity during the cooking process, thereby achieving a tenderized finish. Existing water replenishment systems primarily include a water replenishment device (e.g., a nozzle or steam generator) within the cooking cavity and a water supply device for supplying water to the water replenishment device. However, existing water supply devices suffer from unstable water flow, resulting in poor water supply continuity and, therefore, require further improvement. Utility Model Content

The inner pipe 31 and the base 33 can be fixedly connected or integrally formed. The outer pipe 32 extends upward from the bottom wall of the water tank 2 and is integrally formed with the bottom wall of the water tank 2, thereby achieving better airtightness. That is, the upper end of the outer pipe 32 is located within the water storage chamber 221, and the lower end of the outer pipe 32 is located below the bottom wall of the water tank 2. The inner pipe 31 is inserted upward from the bottom of the outer pipe 32 into the outer pipe 32. When the inner pipe 31 is inserted into the outer pipe 32, the upper ends of the two are aligned. The siphon channel 4 is located between the inner side wall of the sleeve 211 and the outer side wall of the outer pipe 32. The drain channel 311 is located within the inner pipe 31. To ensure better airtightness, the outer pipe 32 is sealed and connected to the inner pipe 31. Specifically, a first sealing ring 5 is provided between the outer pipe 32 and the inner pipe 31. Two first sealing rings 5 ​​can be provided and arranged vertically along the inner side wall of the outer pipe 32, thereby improving the sealing between the outer pipe 32 and the inner pipe 31 and facilitating continuous water supply to the siphon channel 4.

Specifically, the number of the plug-in portion 11 and the slot 331 are both three, and they correspond one to one, and the three slots 331 surround the outside of the second sealing ring 6.

[0043] In some embodiments, such as Figure 2 and Figure 4 As shown, the base 33 is provided with a water outlet pipe 34 which is perpendicular to the drainage channel 311. The water outlet pipe 34 connects the lower end of the drainage channel 311 with the water pump. The water outlet pipe 34 facilitates the drainage of the drainage channel 311 outward. Specifically, the water pump can be connected to the water outlet pipe 34 through a soft water pipe.

[0044] Working principle description:

[0045] During water supply, the water pump is started, and the power of the water pump causes the siphon channel 4 to generate a siphon phenomenon. After the water pump is turned off, the water in the water storage chamber 221 continues to flow into the drainage channel 311 through the siphon channel 4, thereby continuously and stably supplying water to the water replenishment device. When the water supply speed needs to be further accelerated, the water pump can be started again, and the water supply speed can be accelerated by combining the power of the water pump and the siphon power.

[0046] The present invention is not limited to the above optional implementation methods. Under the premise of not conflicting with each other, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in their shape or structure, all technical solutions that fall within the scope defined by the claims of the present invention fall within the scope of protection of the present invention.
