Embodiment one, as shown in fig. 1-2, the utility model provides a zero cold water gas heater, include:
a burner 1, the burner 1 being for burning gas;
the heat exchanger 2 is provided with a water inlet pipe and a water outlet pipe, and the heat exchanger 2 is used for heating water introduced from the water inlet pipe by using heat generated by combustion of the combustor 1 and outputting hot water from the water outlet pipe;
a circulating water pump 3;
the valve module 4 is provided with an outlet and at least two inlets, and the valve module 4 is used for controlling the outlet to be communicated with at least one inlet; wherein, export, circulating water pump 3 with the inlet tube connects gradually.
In the actual use process, after the user starts the zero-cold-water gas water heater, the external gas enters the combustor 1 through the air inlet valve 300. The gas is burned in the burner 1, and the heat generated by the gas combustion heats the water flowing in the heat exchanger 2, so that the cold water delivered from the water supply pipe enters the heat exchanger 2 through the water inlet pipe, and the cold water is heated to form hot water and is output from the water outlet pipe to the water terminal 2000 (such as a shower or a faucet) in the home of the user.
Since there are a plurality of hot water terminals 2000 used in the home of the user, each water terminal 2000 is connected to a corresponding inlet of the valve module 4, except for the water outlet pipe of the heat exchanger 2.
In actual use, when hot water is used, only one of the water terminals 2000 outputs hot water. For this reason, in order to reduce the time of zero cold water waiting and reduce energy consumption, in the zero cold water mode of the zero cold water gas water heater, the valve module 4 controls the corresponding inlet and outlet to communicate, so that the pipeline 1000 where the water using terminal 2000 is located in the use state participates in the zero cold water mode to heat the water in the corresponding pipeline 1000.
Like this, alright with the effectual water yield that reduces zero cold water heating to shorten zero cold water heating's time, simultaneously, can effectual reduction energy consumption, and improved user experience nature.
The main function of the valve module 4 is to communicate the corresponding inlet and outlet as required to satisfy the requirement that the water in the pipeline 1000 where the specific water usage terminal 2000 is located participates in zero cold water heating. To this end, the embodied entities for the valve module 4 may take many forms, as exemplified below in connection with the figures.
In one embodiment, the valve module 4 may be a multi-position multi-way valve, in which the valve module 4 controls communication between a single inlet and an outlet in a one-out-of-one manner. Taking the example of two restrooms in a user's home, the valve module 4 may be a two-position three-way valve having an outlet and two inlets, one of the inlets being connected to the water usage terminal 2000 in one of the restrooms and the other inlet being connected to the water usage terminal 2000 in the other restroom.
In actual use, referring to fig. 1, when the water usage terminal 2000 in the washroom on the left side in fig. 1 is in an operating state, the valve module 4 controls the inlet connected to the left water usage terminal 2000 to be communicated with the outlet, and the inlet connected to the right water usage terminal 2000 to be disconnected from the outlet. In the zero-cold-water mode, the water in the left pipeline 1000 flows into the circulating water pump 3 through the valve module 4, and the circulating water pump 3 drives the water flow into the heat exchange pipe, so as to realize zero-cold-water heating.
In another embodiment, valve islands may be implemented for valve modules 4.
As shown in fig. 3, the valve module 4 includes:
the water flowing channel 41 is provided with the outlet;
and a plurality of switching valves 42 respectively communicating with the water flow passages 41, the valves being provided with the inlets.
Specifically, the water inlet ports of the switch valves form corresponding inlets, each switch valve is connected with the corresponding water using terminal to form a relatively independent pipeline 1000, and water in different pipelines 1000 is controlled to participate in the zero-cold water heating treatment process by independently switching on and off the switch valves.
In actual use, when the water use terminal 2000 in the toilet on the left side in fig. 3 is in an operating state, the valve module 4 controls the on-off valve 42 connected to the left water use terminal 2000 to be opened, and at the same time, controls the on-off valve 42 connected to the right water use terminal 2000 to be disconnected. In the zero-cold-water mode, the water in the left pipeline 1000 flows into the circulating water pump 3 through the valve module 4, and the circulating water pump 3 drives the water flow into the heat exchange pipe, so as to realize zero-cold-water heating.
In some embodiments, in order to ensure that the water flow can smoothly circulate in the zero-cold-water mode, a check valve 43 is further disposed on the switch valve, and the check valve 43 is used for controlling the water flow to flow into the corresponding switch valve.
Specifically, when the gas water heater is in the zero cold water mode, the water in the pipeline 1000 needs to enter the heat exchanger 2 from the valve module 4 to realize the circulation flow. By adding the check valve 43, the check valve 43 can control water to enter only from the inlet of the valve module 4, and the situation that water flows reversely into the valve module 4 through the outlet is avoided, so that the use reliability is improved.
In one embodiment, to facilitate assembly of the valve module 4, the valve module 4 further comprises: a mounting seat 40, wherein a water flowing channel 41 is formed on the mounting seat 40; the on-off valve and the check valve 43 are respectively provided on the mount 40.
Specifically, the mounting seat 40 is used for mounting the switching valve and the check valve 43, and the water flowing channel 41 is formed on the mounting seat 40, so that the switching valve and the water flowing channel 41 can be conveniently connected and mounted. A plurality of connection passages (not shown) are formed in the mounting seat 40, and the check valves 43 are connected to the switching valves through the corresponding connection passages.
In addition, it is also possible to adopt a separate design for the check valve 43 and the on-off valve, i.e., to install the check valve 43 at a position close to the water use terminal. For this purpose, the non-return valve 43 is arranged at a distance from the switching valve, which is connected to the non-return valve 43 via a water line.
The switch valve may be controlled manually or automatically, as will be exemplified below.
In one embodiment, the on-off valve is a manual shut-off valve. When the water heater is used, a user can control the on-off of different pipelines 1000 by switching on and off the manual stop valve according to needs so as to independently control the corresponding pipelines 1000 to participate in zero cold water heating.
In another embodiment, the switching valve is an electric valve. Specifically, the electric valve is controlled by a controller of the gas water heater to automatically control the on/off of the different pipelines 1000. For the specific control mode of the electric valve, a user can trigger the electric valve by operating the control panel of the gas water heater, and no limitation or description is given here.
In a preferred embodiment, the valve module 4 is electrically controlled, and in order to realize that the valve module 4 is automatically controlled to switch the corresponding inlet and outlet connections without manual operation, the valve module 4 further comprises a plurality of flow sensors (not shown) matched with the inlets. The flow sensor is used for detecting whether the water using terminal 2000 connected with the corresponding inlet is in a water using state or not, and further triggering the inlet connected with the water using terminal 2000 to be communicated with the outlet.
Taking the valve module 4 in fig. 3 as an example, when the water usage terminal 2000 in the toilet on the left side in fig. 3 is in an operating state, the flow sensor will detect that the water usage terminal on the left side is in a state of using hot water. And when the gas water heater is in the zero cold water mode, the electric valve on the left side is correspondingly triggered to be opened so as to meet the requirement of zero cold water heating of the pipeline 1000 on the left side.
The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or that equivalents may be substituted for elements thereof; such modifications and substitutions do not depart from the spirit and scope of the present invention, which is claimed.
