Description

Technical Field

[0001] The utility model belongs to the technical field of household appliances, and particularly relates to a sealing structure of a nozzle seat and a gas stove using the sealing structure. Background Art

[0002] During the cooking process of a gas stove, water often leaks from the burner to the igniter below. After a long time, water easily accumulates and is difficult to clean. In the prior art, an easy-to-clean water receiving tray is provided on the surface of the igniter to collect the seeping water, thereby facilitating the cleaning of the accumulated water.

[0003] However, the igniter is provided with a mounting post for mounting the nozzle. Where the mounting post is located, a gap is easily formed between the edge of the post and the water receiving tray, and this gap is difficult to avoid. As a result, moisture that penetrates into the igniter through the gap over time is still difficult to handle, and becomes a relatively hidden sanitary dead corner on the gas stove. Utility Model Content

[0004] To solve the above technical problems, the present invention further improves the sealing structure between the existing igniter and the water receiving tray to prevent water leakage. One of the purposes of the present invention is to provide a sealing structure for the nozzle holder, and the second purpose is to provide a corresponding gas stove.

[0009] The water receiving tray is covered on the sealing gasket, and has at least one sealing portion on the water receiving tray. The sealing portion matches the sealing hole in quantity and corresponds in position. The sealing portion is tightly pressed on the first sealing edge to form a first seal.

[0010] In the above technical solution, a sealing gasket is arranged in a targeted manner, and the outer edge of the nozzle mounting column is sealed by tightly pressing the first sealing edge on the sealing gasket with the sealing portion on the water receiving tray, thereby preventing water leakage therefrom.

[0011] Preferably, a flange is provided on one side of the sealing portion close to the nozzle mounting column, and a first sealing arc surface is formed on the flange toward the first sealing edge, and the first sealing arc surface is tightly pressed on the first sealing edge to form a first seal.

[0012] The flange has at least two functions: one is to prevent water on the water receiving tray from moving to the nozzle mounting column and leaking; the other is to facilitate the formation of a first sealing arc surface at the bend below the flange to form a more fitting and effective sealing structure.

[0013] Further preferably, a sealing bevel is provided on the first sealing edge, and the first sealing arc surface is tightly pressed on the sealing bevel to form a first sealing portion.

[0014] The sealing bevel conforms to the first sealing arc surface, further enhancing the sealing effect.

[0015] Further preferably, a second sealing edge is provided on the periphery of the first sealing edge, the sealing portion is tightly pressed on the second sealing edge to form a second sealing portion, and the second sealing portion cooperates with the first sealing portion to form a double-layer sealing structure.

[0016] Preferably, a sealing groove is provided between the first sealing portion and the second sealing portion, and the sealing portion is tightly pressed on both sides of the sealing groove to form a third sealed cavity with airtightness. By utilizing the sealing properties of the second sealing portion and the first sealing portion themselves, the third sealed cavity has a certain airtightness, thereby obtaining a third barrier to prevent moisture leakage.

[0017] Preferably, it further comprises a stove panel, the inner edge of the stove panel being arranged around the outer periphery of the nozzle seat;

[0018] The water receiving tray has a stove surface covering portion extending to the stove panel, and the stove surface covering portion is sealed with the stove panel via a sealing ring, which is mainly used to prevent moisture on the outer edge of the water receiving tray from transferring to or leaking to the stove panel.

[0019] Preferably, the cooktop covering portion has a cooktop sealing groove with a notch pointing to the cooktop panel, and the sealing ring has a cooktop sealing protrusion protruding toward the cooktop covering portion, and the cooktop sealing protrusion is tightly fitted with the bottom of the cooktop sealing groove to form a fourth sealing point.

[0020] Preferably, a second sealing arc surface is provided on the outer side of the stove top sealing groove wall facing the stove panel end, the sealing ring has a sealing platform, and the second sealing arc surface is tightly fitted with the sealing platform to form a fifth sealing point.

[0021] Preferably, an airtight sixth sealing cavity is provided between the fourth sealing portion and the fifth sealing portion.
