Embodiment 1

[0034] This embodiment describes in detail the nozzle waterproof structure of the present invention.

[0035] The nozzle waterproof structure of the present embodiment includes a sealant cover 1 and a pipe joint 2, such as figure 1 shown. Preferably, the sealant cover 1 includes a mounting portion 11 and a through pipe 12 connected to the mounting portion 11, such as figure 1 shown. More preferably, the installation part 11 is installed on the surface of the object to be sealed and matches the structure of the surface of the object to be sealed, and the through pipe 12 is installed in the nozzle of the object to be sealed. More preferably, the pipe joint 2 is assembled in the through pipe 12 and fixedly connected with the through pipe 12, and the mounting part 11 is closely attached to the surface of the part to be sealed, such as figure 1 shown. The installation part 11 of this embodiment matches the surface structure of the part to be sealed, and it can also be said that...

Embodiment 2

[0050] This embodiment describes the water tank of the present invention in detail.

[0051] The water tank of this embodiment includes a shell and a spout disposed on the shell, and the spout is provided with the spout waterproof structure of any one of the technical solutions in Embodiment 1. Preferably, the nozzle here can be a water inlet nozzle or a water outlet nozzle. In the water tank of this embodiment, the nozzle is provided with the nozzle waterproof structure of any one of the technical solutions in Embodiment 1, so that the nozzle is well sealed and the water tank has excellent waterproof performance.

Embodiment 3

[0053] This embodiment describes the water heater of the present invention in detail.

Abstract

The invention discloses a pipe opening waterproof structure, a water tank and a water heater, relates to the technical field of water heaters, and solves the technical problem of poor sealing effect caused by incapability of completely attaching a sealing rubber cover to a casing in the prior art. The pipe opening waterproof structure comprises a sealing rubber cover and a pipe joint; the sealingrubber cover comprises a mounting part and a through pipe connected with the mounting part; the mounting part is mounted on the surface of a to-be-sealed piece and is matched with the surface structure of the to-be-sealed piece; the through pipe is mounted in a pipe opening of the to-be-sealed piece; the pipe joint is assembled in the through pipe and is fixedly connected with the through pipe; and the mounting part is tightly attached to the surface of the to-be-sealed piece. According to the waterproof structure, the mounting part of the sealing rubber cover is arranged to be of the structure matched with the surface of the to-be-sealed piece, and the through pipe of the sealing rubber cover is fixedly connected with the pipe joint, so that the attaching tightness between the sealing rubber cover and the surface of the to-be-sealed piece can be enhanced, the sealing performance between the sealing rubber cover and the to-be-sealed piece can be improved, and the waterproof performanceof the waterproof structure can be enhanced.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to a nozzle waterproof structure, a water tank and a water heater. Background technique [0002] The installation environment of air-energy water heaters is complex. At present, most air-energy water heaters are installed outdoors, and the requirements for the sealing of the water inlet and outlet pipes are very high. If water enters the pipe mouth, there will be a quality risk of corrosion of the internal heat exchanger. The traditional nozzle is sealed with a sealant cover. This structure requires a tight fit between the sealant cover of the nozzle and the shell of the water heater to ensure that outdoor rainwater cannot penetrate. The existing sealant cover is located on the surface of the casing, and the pipe joint is inserted into the sealant cover and is in hard contact with the sealant cover. [0003] However, since the shell and the sealant cover are only fixed by the...
