Embodiment Construction

[0012] As shown in the attached picture. For the low-temperature automatic emptying device of the solar water heater, an electric control device [4] is installed on the valve of the water inlet pipe [2] of the solar water heater [1] and the valve of the heat collection pipe [3], and a temperature detection device [5] is installed. When the ambient temperature When it is lower than the set value, the electric control device [4] controls to close the water inlet pipe, opens the valve of the heat collection pipe, and drains the water in the heat collection pipe to prevent freezing and cracking.

[0013] The low-temperature automatic emptying device of the solar water heater is equipped with a remote transmission module [6], and when the emptying mechanism is activated, a prompt message is sent to the remote number.

[0014] The low-temperature automatic emptying device of the solar water heater is equipped with a water pressure detection device [7] in the heat collecting pipe [3]...

Abstract

A low temperature based automatic emptier for a solar water heater is characterized in that a valve on an inflow pipe (2) of the solar water heater (1) and valves on thermal collector tubes (3) are provided with an electric controller (4) and a temperature detector (5); when the ambient temperature is lower than a set value, the electric controller (4) controls and closes the inflow pipe and opens the valves on the thermal collector pipes, water in the thermal collector pipes is emptied to prevent freeze-cracking; a remote transmission module (6) sends a reminder message to a remote number when an emptying mechanism is started; water pressure detectors (7) on the thermal collector tubes (3) determine that the specific pipe cracks when the water pressure is unbalanced; a prompting device sends out a prompt message when the thermal collector tubes crack. The low temperature based automatic emptier has the advantages that the ambient temperature can be automatically monitored, and the thermal collector tubes can be preventively emptied in advance to avoid the thermal collector tubes being freeze-cracked when the excessively low ambient temperature may causes damage to the thermal collector tubes.

Description

technical field [0001] The invention relates to an accessory device of a solar water heater. Background technique [0002] Solar water heaters are currently the most popular heat collecting devices, which can maximize the use of solar energy and belong to clean energy. However, the heat collecting tube of the solar water heater is easily cracked by freezing under the condition of low temperature, thereby affecting the normal use of the solar water heater. Contents of the invention [0003] The object of the present invention is to provide an accessory device of a solar water heater that automatically monitors the ambient temperature and protects the heat collecting tube. [0004] The present invention is achieved like this. The low-temperature automatic emptying device of the solar water heater is equipped with an electric control device and a temperature detection device on the water inlet pipe valve and the heat collection pipe valve of the solar water heater. When the...
