The concave structure 41 is disposed opposite to the water inlet pipe orifice of the water outlet connection pipe 12, so that water conveyed by the auxiliary flow channel 111 can more smoothly flow into the water outlet connection pipe 12 at the concave structure 41, so as to ensure smooth flow of water outlet water flow.

As shown in fig. 16 to 17, the present embodiment proposes a water heater including a water heater main body 100. The water heater body 100 may be embodied as an electric water heater, or a water tank of a heat pump water heater, or a water tank of a solar water heater.

When the water heater main body 100 is used in a user's home, it is installed on a wall of the user's home according to installation requirements.

In order to improve the water intake quality of the water heater, a water treatment device 500 may be added between the water intake pipe 200 of the water heater and a water supply pipe in a user's home to filter the water output from the water supply pipe by the water treatment device 500.

In addition, the water treatment apparatus 500 generally includes a mounting body 1 and a filter assembly, the filter assembly including a filter cartridge 2 and a filter flask 3, the mounting body 1 being used to meet the connection requirement of the water inlet pipe 200 of the water heater and the water supply pipe in the user's home, and at the same time, the mounting body 1 being also used to mount the filter cartridge 2 and the filter flask 3 of the filter assembly.

In an embodiment, in order to optimize the appearance effect of the whole machine, the water treatment device 500 is not exposed to the bottom of the water heater after being installed, so that the appearance effect is not deteriorated.

Wherein, the water heater main body 100 is further provided with a decorative cover 400, and the water inlet pipe 200 and the water outlet pipe 300 are arranged at the back of the decorative cover 400, and the water heater is characterized by further comprising a water treatment device 500;

for the water treatment apparatus 500, the filter assembly is disposed generally laterally and hidden at the back of the trim cover 400.

Specifically, the water inlet pipe 200 of the water heater is configured to satisfy the internal water inlet, and the water outlet pipe 300 is configured to output the heated water to the water terminal. The water entering the water inlet pipe 200 can be filtered by the water treatment device 500 to improve the quality of the water entering the water heater.

In order to enable the water treatment device 500 to be installed in a hidden manner, the installation structure of the water treatment device 500 is improved.

Specifically, the filter element 2 and the filter flask 3 of the water treatment device 500 are arranged transversely, and the space at the bottom of the water heater is used for transversely extending, installing and arranging. Thus, the overall height of the water treatment apparatus 500 can be effectively reduced, and the installation requirements of the water treatment apparatus 500 can be satisfied by using the lateral space of the bottom of the water heater.

The installation body 1 of the water treatment apparatus 500 is connected to an external water pipe through a water inlet connection pipe 11 and connected to a water inlet pipe 200 of the water heater body 100 through a water outlet connection pipe 12. And the filter element 2 and the filter flask 3 are arranged on the corresponding connecting ports of the installation main body 1.

In some embodiments, to facilitate installation of the on-site pipeline, the water outlet connection pipe 12 is arranged vertically and extends upwards, and the water inlet connection pipe 11 is arranged laterally.

Specifically, when the water heater is installed in the user's home, the water heater is arranged above the external water pipe arranged on the wall of the user's home, and the water inlet pipe 200 of the water heater and the external water pipe on the wall are arranged in a mutually perpendicular manner. For this purpose, the water inlet connection pipe 11 on the installation body 1 is arranged transversely and extends toward the back of the water heater to meet the requirements of external water pipe connection on the wall. Meanwhile, the water outlet connection pipe 12 on the installation body 1 is vertically arranged and extends upward to meet the connection requirement with the water inlet pipe 200 of the water heater.

Therefore, when the water heater is installed and operated in the home of a user, the connection of the on-site pipeline is more convenient, so that the installation difficulty is reduced.

In some embodiments, there may be various forms for the particular extension of the filter flask 3 and the filter cartridge 2 in the lateral direction.

For example: as shown in fig. 16 and 17, the filter flask 3 and the filter cartridge 2 extend toward the back of the water heater.

In particular, referring to fig. 17, the filter flask 3 and the filter cartridge 2 are laterally arranged on the back of the decorative cover 400 and extend in a direction away from the decorative cover 400.

As shown in fig. 18 and 19, the filter flask 3 and the filter element 2 extend toward the outlet pipe 300 and are arranged between the outlet pipe 300 and the decorative cover 400.

Specifically, referring to fig. 19, the filter flask 3 and the filter cartridge 2 are laterally disposed at the back of the decorative cover 400 and extend from the water inlet pipe 200 toward the water outlet pipe 300. Since the space between the water inlet pipe 200 and the water outlet pipe 300 of the water heater generally does not additionally arrange related functional devices, the filter flask 3 and the filter cartridge 2 can be installed using the space arrangement between the water inlet pipe 200 and the water outlet pipe 300. While the end of the flask 3, which is longer, may also extend beyond the outlet tube 300 and be located between the outlet tube 300 and the decorative cover 400.

Since the filter flask 3 and the filter cartridge 2 are disposed in the region between the water inlet pipe 200 and the water outlet pipe 300 and the decorative cover 400, a space at the rear of the water inlet pipe 200 and the water outlet pipe 300 can be made free to facilitate the connection of the water pipes.

The above embodiments are only for illustrating the technical solution of the present utility model, and are not limiting; although the utility model has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
