Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, specifically to a household appliance. Background Technology

[0002] Existing household appliances, such as sterilizers for sterilizing baby bottles and electric steamers for cooking food, include a base with a heating chamber, a water tank, and a cover over the heating chamber. A water pump is fixed to the lower end of the base. One end of the water pump is connected to the water tank through an inlet pipe, and the other end is connected to the inlet of the heating chamber through an outlet pipe. Because the inlet is lower than the outlet of the water tank, the water pump stops working after pumping a certain amount of water into the heating chamber. However, due to the siphon effect, even after the water pump stops working, water in the tank will continue to enter the water pump through the inlet pipe and then enter the heating chamber. The water inflow rate is not as fast as the pumping rate, which affects the normal operation of the household appliance and provides a poor user experience. Utility Model Content

[0003] The purpose of this utility model is to provide a household appliance that solves the problem that water in the water tank continues to flow into the heating chamber after the water pump stops working.

[0004] This utility model relates to a household appliance, comprising a base with a heating chamber, a water tank, and a cover over the heating chamber.

[0026] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0027] like Figures 1 to 4As shown, a household appliance of this utility model includes a base 1 with a heating chamber 11, a water tank 2, and a cover 3 covering the heating chamber 11. A water pump 4 is fixed at the lower end of the base 1. One end of the water pump 4 is connected to the water tank 2 through an inlet pipe 5, and the other end is connected to the water inlet 12 of the heating chamber 11 through an outlet pipe. A waterproof and breathable valve 6 is provided between the water pump 4 and the water inlet 12. The outlet pipe includes a first outlet pipe 7 and a second outlet pipe 8. The waterproof and breathable valve 6 is fixed at a position higher than the highest water level of the water tank 2. One end of the waterproof and breathable valve 6 is connected to the water pump 4 through the first outlet pipe 7, and the other end is connected to the water inlet 12 through the second outlet pipe 8. Compared with the prior art, the household appliance of this utility model has the advantages of a waterproof and breathable valve 6 between the water pump 4 and the water inlet 12, and the water outlet pipe including a first water outlet pipe 7 and a second water outlet pipe 8. The waterproof and breathable valve 6 is fixed at a position higher than the highest water level of the water tank 2. One end of the waterproof and breathable valve 6 is connected to the water pump 4 through the first water outlet pipe 7, and the other end is connected to the water inlet 12 through the second water outlet pipe 8. After the water pump 4 stops working, since the waterproof and breathable valve 6 is connected to the atmosphere and fixed at a position higher than the highest water level of the water tank 2, the water in the water tank 2 will no longer flow into the waterproof and breathable valve 6, and therefore cannot flow into the heating chamber 11. This effectively blocks the water in the water tank 2 from continuing to flow into the heating chamber 11, ensuring the normal operation of the household appliance and providing a better user experience.

[0028] Specifically, such as Figures 5 to 7 As shown, the waterproof and breathable valve 6 includes a valve body 61, a waterproof and breathable membrane 62, and a pressure strip 63. The valve body 61 is provided with an inlet connector 64, an outlet connector 65, and a vent 66. The waterproof and breathable membrane 62 is fixed between the valve body 61 and the pressure strip 63 and covers the vent 66. The waterproof and breathable membrane 62 covers the vent 66, preventing water from flowing out of the vent 66 while ensuring that the waterproof and breathable valve 6 is connected to the atmosphere. The waterproof and breathable membrane 62 is made of polyurethane, polytetrafluoroethylene, or polyester.

[0029] Furthermore, the inlet connector 64 is connected to the first outlet pipe 7; the outlet connector 65 is connected to the second outlet pipe 8, and a flow meter 10 is connected to the second outlet pipe 8. The flow meter 10 is used to monitor the amount of water flowing into the heating chamber 11.

[0030] The valve body 61 has a buckle 611 on each side, and the pressure strip 63 has a buckle hole 631 that can be fastened to the buckle 611. The buckle 611 and the buckle hole 611 cooperate to facilitate the removal and replacement of the waterproof and breathable membrane 62 when it fails.

[0031] Optionally, the pressure strip 63 is provided with a through hole 632 that is directly opposite to the vent hole 66. When the buckle hole 611 of the pressure strip 63 is fastened to the buckle 611 of the valve body 61, the through hole 632 will be directly opposite to the vent hole 66, ensuring the breathability of the waterproof and breathable valve 6.

[0032] More specifically, the base 1 has an upwardly extending protrusion 13, the water tank 2 is installed on one side of the protrusion 13, and the cover 3 is installed on the other side of the protrusion 13. A bracket 9 is installed inside the protrusion 13, and a waterproof and breathable valve 6 is fixed to the upper end of the bracket 9; the lower end of the bracket 9 is fixedly connected to the base 1. The bracket 9 is set inside the protrusion 13 so that the bracket 9 is not exposed, ensuring the overall aesthetic appearance of the product.

[0033] In addition, the protrusion 13 is provided with a recess 14 that can accommodate the water tank 2. The recess 14 has an "L" shaped cross section. The "L" shaped recess 14 provides support for the water tank 2 when it is installed on the base 1 and subjected to external force, effectively preventing the water tank 2 from falling off the base 1.

[0034] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions or improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
