Abstract

The invention discloses a heat recovery device of a water heater. The heat recovery device comprises a mounting plate; the mounting plate is provided with a first water inlet pipe, a water return pipe and a second water inlet pipe and a water outlet pipe, wherein the first water inlet pipe is connected with the second water inlet pipe through the water return pipe, the first water inlet pipe is connected with the water outlet pipe, the second water inlet pipe is communicated with the water return pipe, the water return pipe is communicated with the first water inlet pipe, and the first water inlet pipe is communicated with the water outlet pipe. The heat recovery device of the water heater of the invention has the advantages of simple structure, convenient manufacture, half hot water back flowing effect and saving-energy performance.

Description

A kind of heat reclaim unit of water heater

Technical field

The present invention relates to parts of water heater field, particularly relate to a kind of heat reclaim unit of water heater.

Background technology

In water heater used on the market at present, at the water service pipe that the device of water supply heating comprises the installing plate for installing water pipe and installs onboard, because heating is heated in the below of installing plate, when the water in water pipe absorbs after enough heats, still there is partial heat unnecessary, thus cause the loss of heat; And if water service pipe is installed in continuation above water service pipe, the water in the water service pipe of top can be caused due to shortage of heat to cause temperature inadequate.

Summary of the invention

The object of the present invention is to provide a kind of heat reclaim unit of water heater, its structure is simple, easily manufactured, has half hot water return effect, reaches the effect of saving the energy.

In order to achieve the above object, technical scheme of the present invention is:

A kind of heat reclaim unit of water heater, comprise installing plate, described installing plate is provided with the first water inlet pipe, return pipe, the second water inlet pipe and outlet pipe, described first water inlet pipe is connected by return pipe with the second water inlet pipe, and described first water inlet pipe is connected with outlet pipe; Described second water inlet pipe is communicated with return pipe; Described return pipe is communicated with the first water inlet pipe; Described first water inlet pipe is communicated with outlet pipe.

Further: described first water inlet pipe and outlet pipe is integrally manufactured forms.

Further: described second water inlet pipe and return pipe are threaded connection, described return pipe and the first water inlet pipe are threaded connection.

Further: between described second water inlet pipe and return pipe, the first sealing ring is installed, the second sealing ring is installed between described return pipe and the first water inlet pipe.

The invention has the beneficial effects as follows: its structure of the present invention is simple, easily manufactured, has half hot water return effect, reach the effect of saving the energy.

Detailed description of the invention

Embodiment 1

The heat reclaim unit of a kind of water heater as shown in Fig. 1-2, comprise installing plate 1, described installing plate 1 is provided with the first water inlet pipe 2, return pipe 3, second water inlet pipe 4 and outlet pipe 5, described first water inlet pipe 2 is connected by return pipe 3 with the second water inlet pipe 4, and described first water inlet pipe 2 is connected with outlet pipe 5; Described second water inlet pipe 4 is communicated with return pipe 3; Described return pipe 3 is communicated with the first water inlet pipe 2; Described first water inlet pipe 2 is communicated with outlet pipe 5; Make half hot water return in the second water inlet pipe in the first water inlet pipe, make half hot water continue absorption portion heat, reach temperature required, thus reach energy-conservation effect.

Further: described first water inlet pipe 2 forms with outlet pipe 5 is integrally manufactured.

Further: described second water inlet pipe 4 is threaded connection with return pipe 3, and described return pipe 3 and the first water inlet pipe 2 are threaded connection.

Further: between described second water inlet pipe 4 and return pipe 3, first sealing ring 6 is installed, between described return pipe 3 and the first water inlet pipe 2, second sealing ring 7 is installed.

The heat reclaim unit of a kind of water heater of the present embodiment, its structure is simple, easily manufactured, has half hot water return effect, reaches the effect of saving the energy.
