Embodiment （ 1

[0022] figure 1 It is a structural schematic diagram of the hot water circulation device based on the instant water heater of the present invention, please refer to figure 1 , a hot water circulation device based on an instant water heater in the present invention, including an instant water heater 1, wherein a hot water booster pump 2 is installed on the outlet pipe 12 or the inlet pipe 11 of the instant water heater 1 Above, the water inlet pipe 11 is connected with a water supply pipe 14 and a water return pipe 13 respectively, and the water inlet pipe 11, the water supply pipe 14, the water outlet pipe 12, and the water return pipe 13 form a water circulation circuit, and the function of the booster pump 1 is to provide water supply for the water circulation circuit. The water pressure enables the water to circulate in the water circulation loop, wherein the advantage of using the instant water heater 1 for heating in the circulating water circulation loop is that instant ...

Embodiment （ 2

[0030] figure 2 It is a structural schematic diagram of Embodiment 2 of the hot water circulation device based on the instant water heater of the present invention, please refer to figure 2, on the basis of Embodiment 1, the controller 8 of the hot water circulation device based on the instant water heater of the present invention also has a timing function, and the timing function is realized by a timing module 81 arranged in the controller 8, and the user can Set the time period according to one's own needs, and within the timing time, the controller 8 judges whether the water temperature obtained by the temperature-sensing probe 3 reaches a preset temperature. If the water temperature obtained by the temperature-sensing probe 3 does not reach a preset temperature, the controller 8 controls The booster pump 2 continues to work, so that the water in the water circulation loop is continuously circulated, and is continuously heated by the instant water heater 1. After a perio...

Embodiment （ 3

[0033] image 3 It is a flow chart of the hot water circulation method based on the instant water heater of the present invention, please refer to image 3 , the present invention is a hot water circulation method for an instant water heater, which includes: the user sets the temperature according to actual needs, step 101 opens the faucet to trigger a booster pump to generate a circulating water flow, the faucet is opened and then closed, It does not need to be turned on continuously. After the booster pump detects the water flow, the controller performs control according to the received trigger signal and the temperature detected by the temperature sensor. Step 102 detects the data of the temperature sensor. If the temperature sensor detects that the water temperature is higher than the set value Then step 104 booster pump does not pressurize the water in the water circulation loop, if the temperature sensor detects that the water temperature is lower than the set value, the...

Abstract

The invention discloses a device and a method for hot water circulation based on an instant water heater. The device for hot water circulation comprises the instant water heater, wherein a hot water boosting pump is mounted on a water outlet pipe or a water inlet pipe of the instant water heater and used for providing water pressure for water in the device for hot water circulation; a temperature sensing probe is mounted on the water outlet pipe or the water inlet pipe and used for acquiring a water temperature in the device for hot water circulation; a controller is connected with the temperature sensing probe and the boosting pump respectively and used for judging whether the water temperature acquired by the temperature sensing probe achieves a preset temperature, if so, the controller controls the boosting pump to stop working, and if not, the boosting pump continues to work. The device and the method for hot water circulation based on the instant water heater disclosed by the invention have timing function and can heat within a set time and heat in other time ranges through trigging, thus realizing dual effects of energy saving and water saving.

Description

technical field [0001] The present invention relates to a hot water circulation device and method, in particular to a hot water circulation device and method based on an instant water heater. Background technique [0002] At present, the hot water circulation system used in home decoration at home and abroad is divided into two types: non-circulation and circulation. The non-circulation method will greatly waste water resources, which is no longer suitable for the current low-carbon requirements and the comfort of water is also very low, especially for large The room type is only suitable for small room types; so most of the large room type families now use the hot water circulation system to provide hot water. [0003] The hot water circulation system in the prior art mostly adopts the temperature sensing type, the timing temperature sensing type, the manual delay type, etc. The above-mentioned hot water circulation systems all add a return pipe to the hot water piping syst...
