Abstract
Description
Technical Field
[0001] This utility model relates to a kettle used in a home or office and a component installed in the kettle for adding water. It relates to a probe that also detects high water levels, so as to improve the use effect of the high water level probe and optimize the water inlet structure of the electric kettle. Background Technology
[0002] In traditional technology, an electric kettle consists of a kettle body and a kettle stand. The kettle body contains an electric heating element, while the kettle stand is equipped with a power supply device. A coupler is used to supply power from the kettle stand to the electric heating element in the kettle body. Typically, the conductive metal part in the coupler is made into a ring shape so that the kettle body can be inserted into the kettle stand at any angle and an electrical connection can be achieved.
[0003] In existing technology, electric kettles are equipped with a water filling mechanism, which uses a water filling pipe to introduce water into the kettle body. Currently, electric kettles on the market have added pipes to the kettle base and the bottom of the kettle body, enabling water to be supplied from the bottom of the kettle body to the kettle body, thereby automating the water filling process and bringing convenience to users.
[0004] In this type of electric kettle, the water level is automatically monitored by using a water level probe installed in the water filling pipe to detect whether the water level in the kettle is high. When the water level is high, the controller will shut off the water pump to stop the water from entering.
[0005] Typically, water level probes are conductive, and their outer surface must be insulated. High-level probes are positioned high inside the vessel, requiring a supporting tube coated with an electrically insulating material. Because of impurities in the water, these impurities easily form scale on the coating. When removing the scale, the coating can easily peel off, causing the detected water level to drop and rendering the high-level probe ineffective. Summary of the Invention
[0006] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a water inlet structure and electric kettle that also has water level detection. The water inlet structure is hidden in the handle, which can eliminate the need for water filling pipes set in the chassis. The high water level probe is set at the water outlet, which can avoid frequent contact with water.
[0007] The water inlet structure of this utility model, which also has water level detection, is achieved by the following scheme:
[0008] A water inlet structure that also functions as a water level detection device includes a water level probe, an inlet fitting, a sealing gasket, and a nut. The inlet fitting is characterized by being a four-step cylindrical structure: the first step is a retaining ring, the second step is a through ring, the third step is a threaded ring, and the fourth step is a connecting pipe. The through ring and the threaded ring both have grooves formed on their sidewalls. The water level probe is L-shaped, with its horizontal portion placed within the grooves of the through ring and the threaded ring, and its vertical portion extending downwards. The sealing gasket can be fitted onto the second step and is blocked by the first step, enclosing the horizontal portion of the water level probe within it. The nut can be screwed into the nut ring to secure the sealing gasket.
[0009] This utility model relates to an electric kettle, which is achieved through the following solution:
[0010] An electric kettle includes a lid, a body, and a base; the base is fitted with a coupler suitable for bottom water intake and a heating element; characterized in that the body includes a pitcher and a handle, the upper part of the pitcher has a through hole, and the upper end of the handle is mounted on the pitcher through the aforementioned water inlet structure that also functions as a water level detection device; wherein, the water inlet device extends from the inside of the pitcher through the through hole, a retaining ring is placed against the inner wall of the through hole, and a sealing gasket can be squeezed to fit against the inner wall of the pitcher, allowing the vertical part of the water level probe to be suspended in the pitcher, and is fixed by a nut passing through a connecting pipe and screwed onto a threaded ring, and the connecting pipe is connected to the water inlet of the coupler by a water pipe.
[0011] In this way, water can be introduced from the inlet of the coupler through the water pipe, directed to the connecting pipe, and then introduced into the kettle body from the outlet of the inlet fitting.
[0012] This invention creates a water inlet structure that also has a water level detection function and an electric kettle. The water inlet structure can fix the handle to the kettle body and seal the water outlet to prevent water from flowing into the handle. In particular, the water outlet can be set at the upper end of the handle to guide water into the kettle without the need for a special water filling pipe.
[0013] This utility model relates to a water inlet structure that also functions as a water level detector and its electric kettle. The water level probe is suspended high above the water outlet of the kettle body, eliminating the need for components such as a water filling pipe. This avoids the need for insulation treatment on its outer layer and also avoids the risk of the insulation layer peeling off due to frequent contact with water and the need to clean it to prevent dirt buildup.
[0014] This water inlet structure and electric kettle also features water level detection. The water level probe is suspended high above the water outlet of the kettle body. When water is introduced, the force generated by the water pump propels the water directly from the outlet to the center of the kettle body, without contacting the water level probe. This prevents confusion in water level detection during water intake. The water level probe only sends a signal when the water level rises to contact the probe, thus ensuring the accuracy of the detection. Attached Figure Description
