Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments, it being understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention.
In the following description, suffixes such as "module", "component", or "unit" used to denote elements are used only for facilitating the explanation of the present invention, and have no specific meaning in itself. Thus, "module", "component" or "unit" may be used mixedly.
In order to solve the problem that the water outlet temperature of the wall-mounted furnace faucet in the prior art is unstable in a short time and needs a user to wait, the technical problem of user experience is reduced. An embodiment of the present invention provides a zero-cold-water outlet device of a wall-hanging stove, as shown in fig. 1, and fig. 2 is a schematic physical structure diagram of the zero-cold-water outlet device of the wall-hanging stove according to the embodiment of the present invention; the apparatus shown in fig. 1 comprises:
the temperature sensor 10 is arranged on a pipeline between the domestic water outlet end 7 of the wall-mounted furnace and a water tap 12 and used for monitoring the outlet water temperature of the pipeline;
and the electric heating section 9 is arranged between the domestic water outlet end 7 and the water tap 12 and is used for heating the water in the pipeline when the outlet water temperature is lower than the preset outlet water temperature.
From this, electric heating section 9 and temperature sensor 10's cooperation is used, can guarantee as far as possible that the leaving water temperature is greater than or equal to predetermines leaving water temperature, helps leaving water temperature to reach the demand fast, and remain stable, reduced user's latency, promoted user's use and experienced.
In a possible implementation, the electrical heating section 9 may be disposed on the pipeline for heating the water flowing out of the plate heat exchanger 8 and the water in the pipeline when the outlet water temperature is lower than a preset outlet water temperature. When a user opens the faucet 12, the three-way reversing valve 2 in the wall-mounted boiler system switches the water path from the heating mode to the bathroom mode, hot water in circulation in the system passes through the plate heat exchanger 8 and exchanges heat with the domestic water inlet 5, and bathroom water is subjected to first-stage heating. In the conventional waterway system, because the temperature of the domestic water inlet 5 is low, the outlet water temperature cannot reach the preset outlet water temperature immediately when passing through the plate heat exchanger 8, and a section of cold water exists in a pipeline between the domestic water outlet end 7 of the wall-hanging stove and the water tap 12, so that a user needs to discharge the part of water first and then starts to flow out the hot water.
Therefore, a user can set a zero-cold-water outlet device on the pipeline (at the front end of the water faucet 12), and cold water originally existing in the pipeline is quickly heated through the electric heating section 9 in the zero-cold-water outlet device. Meanwhile, the electric heating section 9 has already carried out the first-stage heating to the water passing through the plate heat exchanger 8, but the water temperature has not yet reached the user's demand has carried out the second-stage heating, reduces the waiting time that the water temperature is invariable.
In a possible implementation manner, the electric heating section 9 may also be arranged in the water mixing device for heating the water in the water mixing device; wherein, the water mixing device is positioned between the domestic water outlet end 7 and the water tap 12. The water mixing device can be a water mixing tank, the shape of the water mixing device is not limited, and a user can select the water mixing device according to actual needs. After the electric heating section 9 is arranged in the water mixing device, the electric heating section 9 heats the water in the water mixing device, and when the temperature of the water in the water mixing device is constant, the water outlet of the water faucet 12 is started. After the faucet 12 is turned on, the water in the water mixing device needs to reach a preset temperature, and no water flows out of the faucet 12.
From this, water mixing device also can reach the effect of water storage, and wait to the invariable back of temperature among the water mixing device, provide the user again, low use experience who influences the user when can avoiding out the water temperature.
In addition, the above-described implementation is applied to a scene after the wall-hanging stove is switched from the heating mode to the bathroom mode, and accordingly, the temperature sensor 10 may be further used to monitor the outlet water temperature after the wall-hanging stove is determined to be switched from the heating mode to the bathroom mode. The invention does not limit the temperature sensor 10 and the electrical heating section 9 to operate when the wall-hanging stove is in the bathroom mode. But can work at any time, for example, a cold water return pipe and a water pump can be added in the water path system, and the electric heating section 9 can continuously heat the water flowing out of the plate heat exchanger 8 and the water in the pipeline in a circulating manner. It is ensured that hot water flows out as soon as the user turns on the tap 12. The advantage of this example is that the user can use the hot water at any time without waiting. However, the energy consumption of this example is large, and even if the user does not use the bath water, that is, the wall-hanging stove is in the heating mode, the electric heating section 9 continues to heat the water in the water return pipe, and waits for the heat in the water return pipe to be radiated and then heated. In a possible implementation manner in the embodiment of the present invention, after the temperature sensor 10 is switched to the bathroom mode by monitoring the wall-mounted furnace in real time or in sections, the temperature of the outlet water of the bathroom water is ensured to be stable after switching, and the problem of energy consumption for continuously and circularly heating, dissipating heat, and reheating the hot water in the water return pipe is solved. In summary, the user can set the operation modes of the electric heating section and the temperature sensor according to the actual needs of the user.
In one possible implementation, the zero-cold-water outlet device further includes: the flow control device 11 is arranged on the pipeline, connected with the temperature sensor 10, and used for receiving the outlet water temperature fed back by the temperature sensor 10 and controlling the outlet water flow of the water faucet 12 to be reduced to a first preset flow when the outlet water temperature is lower than a preset outlet water temperature; and the flow control device 11 is further configured to gradually release the limitation on the outlet water flow when the difference between the outlet water temperature and the preset outlet water temperature gradually decreases to zero, so that the outlet water flow gradually increases to a second preset flow.
It can be understood that when the wall-hanging stove is just switched from the heating mode to the bathroom mode, the temperature is low and the temperature is in a temperature-rising state. The flow control device 11 can automatically adjust after receiving the temperature signal fed back by the temperature sensor 10, so that the outlet water flow is reduced, the water is sufficiently heated at a small flow, and the outlet water temperature is ensured. When the water temperature rises, the flow control device 11 gradually releases the restriction on the water outlet flow, so that the water outlet flow rises to a second preset flow (which can be the maximum water outlet flow), and the electric heating section 9 is disconnected. Therefore, the phenomenon that the rising of the outlet water temperature is influenced due to the overhigh outlet water flow can be avoided, the outlet water temperature is further enabled to reach the preset outlet water temperature quickly, the waiting time of a user is further reduced, and the use experience of the user is improved.
The corresponding relation between the water outlet flow and the water outlet temperature can be set by a user, and a proper corresponding relation can also be determined by a manufacturer after a plurality of in-factory inspections.
The temperature control temperatures (i.e. the preset outlet water temperatures) of the temperature sensor 10 and the flow control device 11 can be set by a user at an external zero-cold-water outlet device (e.g. on a control panel or a remote controller), so that the user experience is further guaranteed, and the comfort is improved.

and step S302, when the water outlet temperature is lower than the preset water outlet temperature, starting the electric heating section so as to heat the water in the pipeline.
The water outlet temperature can be monitored after the wall-mounted furnace is determined to be switched from the heating mode to the bathroom mode.
From this, electric heating section and temperature sensor's cooperation is used, can guarantee as far as possible that the leaving water temperature is greater than or equal to predetermines leaving water temperature, helps leaving water temperature to reach the demand fast, and remain stable, reduced user's latency, promoted user's use and experienced.
In a possible implementation manner, the step S302 of starting the electric heating section when the leaving water temperature is lower than the preset leaving water temperature, so as to heat the water in the pipeline includes: heating the water flowing out of the plate heat exchanger and the water in the pipeline; or heating the water in the water mixing device, wherein the water mixing device is positioned between the domestic water outlet end and the water faucet.
From this, water mixing device also can reach the effect of water storage, and wait to the invariable back of temperature among the water mixing device, provide the user again, low use experience who influences the user when can avoiding out the water temperature.
In one possible implementation manner, after monitoring the outlet water temperature of the pipeline between the domestic water outlet end and the water faucet in step S301, the method further includes: when the water outlet temperature is lower than the preset water outlet temperature, controlling the water outlet flow of the faucet to be reduced to a first preset flow through the flow control device; when the difference between the outlet water temperature and the preset outlet water temperature is gradually reduced to zero, the limitation on the outlet water flow is gradually released, so that the outlet water flow is gradually increased to a second preset flow.
Therefore, the phenomenon that the rising of the outlet water temperature is influenced due to the overhigh outlet water flow can be avoided, the outlet water temperature is further enabled to reach the preset outlet water temperature quickly, the waiting time of a user is further reduced, and the use experience of the user is improved.
Fig. 4 shows a flow chart of a zero-cold-water outlet method according to an embodiment of the present invention, and as shown in fig. 4, the method includes:
s401, switching a user to bathroom water;
and step S402, whether the water temperature reaches the temperature set by the user or not. If so, go to step S403; if not, step S404 is performed.
