Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present application more apparent, the technical solutions of the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments of the present application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
It should be noted that, in the description of the present application, terms such as "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, which are merely for convenience of description, and do not indicate or imply that the apparatus or elements must have a specific orientation, be constructed and operated in a specific orientation, and thus are not to be construed as limiting the present application. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
As shown in fig. 1-2, this embodiment proposes a gas water heater, including:
a housing 100, on which a water inlet pipe 101 and a water outlet pipe 102 are provided on the housing 100;
a burner 200, the burner 200 for burning a combustible gas;
a heat exchanger 300, the heat exchanger 300 for supplying water to flow and heating the water using heat generated from the burner 200; wherein the water inlet pipe 101 and the water outlet pipe 102 are respectively connected with the heat exchanger 300.
Specifically, in the actual use process, water enters the heat exchanger 300 through the water inlet pipe 101, the burner burns fuel gas to heat the water flowing through the heat exchanger 300, and the heated water is output through the water outlet pipe 102. However, in the process of using hot water by a user, when the use of hot water is restarted after the water is turned off for a short time, the waste heat generated by the burner after the water is turned off continuously heats the water in the heat exchanger, and the water in the heat exchanger is further heated after the burner is ignited, at this time, the temperature of the water output from the water outlet pipe 102 is too high, and the user is easy to be scalded.
Therefore, by disposing the water outlet temperature control module 400 between the water inlet pipe 101 and the water outlet pipe 102, and controlling the water outlet temperature control module 400 at the water outlet temperature control module 400, the water outlet temperature control module 400 will control the mixing of cold water and hot water according to the inlet water temperature, thereby achieving the function of adjusting the water temperature. After the mixing treatment by the water outlet temperature control module 400, the output water temperature is not too high, so that the fluctuation range of the water outlet temperature is effectively restrained, and the user experience is improved.
For the concrete entity of the water outlet temperature control module 400, the following structure may be adopted. As shown in fig. 3 to 6, the outlet water temperature control module 400 includes: the water inlet tee joint 1, the mechanical temperature control assembly 2 and the connecting pipe 3.
Wherein, the water inlet tee joint 1 is provided with an inlet 11 and two outlets 12; the inlet 11 is connected to an external water supply for the introduction of tap water.
The mechanical temperature control assembly 2 comprises a tube body 21, a core 22 and a temperature-sensing driving piece 23, wherein one end of the tube body 21 is provided with an end cover 210, the other end of the tube body 21 is provided with a water outlet 211, a first mounting opening 212 and a second mounting opening 213 are formed in the side wall of the tube body 21, the core 22 is slidably arranged in the tube body 21 and used for partially or completely shielding the second mounting opening 213, the temperature-sensing driving piece 23 is positioned in the tube body 21, and the temperature-sensing driving piece 23 is made of a memory alloy material and used for driving the core 22 to slide in the tube body 21 according to the water temperature of the water outlet 211.
One pipe orifice of the connecting pipe 3 is connected with one of the outlets, and the other pipe orifice is connected with the second mounting opening 213; and the other outlet of the water inlet tee 1 is connected with a water inlet pipe 101 in the gas water heater.
In actual use, the outlet water temperature control module is installed between the water inlet pipe 101 and the water outlet pipe 102. The concrete connection mode is as follows: the inlet tee 1 is connected to the inlet pipe 101 through one of said outlets, while the second mounting opening 213 of the pipe body 21 is connected to the outlet pipe 102.
In the use process of the user, tap water enters the heat exchanger 300 through the water inlet tee joint 1, water in the heat exchanger 300 is heated by the burner 200 to form hot water, and the hot water enters the pipe body 21 through the first mounting port 212 and is output from the water outlet 211. In the process of outputting hot water through the water outlet 211, the temperature-sensing driving member 23 is made of a memory alloy material, and is deformed according to the different water outlet temperatures of the water outlet 211, so as to drive the core 22 to move, and the second mounting opening 213 is opened and closed by moving the core 22.
The specific process is as follows: when the outlet temperature of the outlet water 211 is higher, the temperature-sensing driving member 23 deforms and drives the core 22 to leave the second mounting opening 213, so as to open the second mounting opening 213, and as the water temperature increases, the deformation degree of the temperature-sensing driving member 23 continues to increase so as to increase the opening degree of the second mounting opening 213.
Conversely, as the outlet temperature of the outlet 211 decreases, the temperature-sensing driving member 23 gradually resets to increase the area of the core 22 covering the second mounting opening 213, and when the outlet temperature of the outlet 211 is low and hot and cold water mixing is not required, the core 22 completely covers the second mounting opening 213 to intercept the inflow of cold water.
For the end cap 210 arranged on the pipe body 21, the end cap 210 can be independently connected with the pipe body 21 in a threaded manner to seal one end of the pipe body 21; alternatively, the end cap is of unitary construction with the tube 21.
In some embodiments, to facilitate installation of the temperature-sensitive driving member 23, a collar 214 may be provided on the inner pipe wall of the pipe body 21, and the temperature-sensitive driving member 23 is disposed between the collar 214 and the core 22.
Specifically, by disposing the retainer 214 on the inner pipe wall of the pipe body 21, the retainer 214 can perform a function of mounting and supporting the temperature-sensitive driving member 23, and on the other hand, the retainer 214 is located in the pipe body 21 and is close to the water outlet 211, so that the retainer 214 can ensure smooth output of water from the water outlet 211.
In some embodiments, the positions of the first mounting port 212 and the second mounting port 213 may take a variety of forms, and are described below in conjunction with the accompanying drawings.
In one embodiment, as shown in fig. 4, the first mounting port 212 is disposed proximate to the water outlet 211 and the second mounting port 213 is disposed distal to the water outlet 211. Specifically, the hot water outputted from the heat exchanger 300 in the gas water heater directly flows to the water outlet 211 through the first mounting port 212, and the second mounting port 213 disposed away from the water outlet 211 introduces the cold water when the core 22 opens the second mounting port 213.
Wherein, for the temperature-sensitive drive member 23, it may be extended with an increase in temperature, or may be retracted with an increase in temperature. For this reason, in the case where the temperature-sensitive drive member 23 is stretched with an increase in temperature, as shown in fig. 4, the core 22 is used only to open or close the second mounting port 213. In the case where the temperature-sensitive driving member 23 is retracted with an increase in temperature, as shown in fig. 5, the temperature-sensitive driving member 23 is retracted with an increase in the water temperature of the water outlet 211; a first cavity 201 is formed between the core 22 and the end cover, and a first through hole 221 communicated with the first cavity 201 is further formed in the core 22; the water flowing in from the second installation port 213 first enters the first chamber 201 and flows to the water outlet 211 through the first through hole 221. Specifically, when the cold water and the hot water are required to be mixed, as the water temperature of the water outlet 211 increases, the temperature-sensing driving piece 23 retracts, so that the core 22 moves towards the water outlet 211. The core 22 exposes the second mounting port 213 such that the second mounting port 213 communicates with the first cavity 201, and cold water entering from the second mounting port 213 enters the first cavity 201 first and then flows to the water outlet 211 through the first through hole 221 to mix cold and hot water.
In addition, in order to avoid interference between water flowing into the first mounting port 212 and the second mounting port 213, a first seal ring 222 may be disposed on the outer periphery of the core 22, the first seal ring 222 is abutted against the inner wall of the pipe 21, the first seal ring 222 is located between the first mounting port 212 and the second mounting port 213, and the core 22 is further used to partially shield the first mounting port 212.
Specifically, after the core 22 is installed in the pipe body 21, the first sealing ring 222 presses against the inner pipe wall of the pipe body 21, and separates the first installation opening 212 from the second installation opening 213, so that the water flowing in through the second installation opening 213 can only flow out through the first through hole 221.
In yet another embodiment, as shown in fig. 6, the first mounting port 212 is disposed away from the water outlet 211 and the second mounting port 213 is disposed proximate to the water outlet 211; the outer periphery of the core 22 is provided with a second sealing ring 223, the second sealing ring 223 is attached to the inner pipe wall of the pipe 21, the second sealing ring 223 is positioned between the first mounting port 212 and the second mounting port 213, a second cavity 202 is formed between the core 22 and the end cover, and a second through hole 224 communicated with the second cavity 202 is also formed in the core 22; the water flowing in from the first mounting port 212 first enters the second chamber 202 and flows to the water outlet 211 through the second through hole 224.
Specifically, the hot water output from the heat exchanger 300 in the gas water heater can enter the second cavity 202 through the first mounting port 212, and then, the hot water flows to the water outlet 211 through the second through hole 224. For the second mounting opening 213, the temperature-sensing driving member 23 controls the movement of the core 22, so as to switch the second mounting opening 213, thereby mixing the cold water and the hot water. Likewise, the first mounting port 212 and the second mounting port 213 can be effectively spaced apart by the second seal 223.
In some embodiments, to more effectively avoid hot water scalding the user, it also serves to partially conceal the first mounting port 212 for the movable core 22. Specifically, as the water temperature of the water outlet 211 increases, the core 22 moves in the pipe body 21, thereby opening the second installation opening 213. While the opening degree of the second mounting opening 213 gradually increases as the water temperature of the water outlet 211 continues to rise, and at the same time, the core 22 moves toward the first mounting opening 212 and partially shields the first mounting opening 212.
In other embodiments, as shown in fig. 7-8, for the temperature-sensing driving member 23, a spring plate made of a memory alloy may be used, or the temperature-sensing driving member 23 is a memory spring. Taking the temperature-sensing driving piece 23 as a memory spring for example, one end of the memory spring is arranged on the retainer 214, and the other end of the memory spring is arranged on the core 22. The memory spring can automatically stretch and retract according to the water outlet temperature of the water outlet 211 so as to adjust the mixing degree of cold water and hot water.
In some embodiments, in order to facilitate the user or operator to adjust the temperature of the trigger water, the water outlet temperature control module further comprises an adjusting component 4, the adjusting component 4 comprises a screw 41 and a baffle rod 42, and the baffle rod 42 is arranged at one end of the screw 41; the end cap is provided with a threaded hole (not marked), a screw 41 is in threaded connection with the threaded hole, the screw 41 penetrates through the core 22 and extends into the memory spring, and a blocking rod 42 transversely penetrates through the memory spring and is abutted against a spring ring of the memory spring.
Specifically, the factory operator or user can adjust the number of turns of the memory spring involved in expansion and contraction by rotating the screw 41, thereby realizing control of the expansion and contraction amount of the memory spring, and thus, the trigger temperature of the cold and hot water mixing can be adjusted. Similarly, in some special cases, when the user needs to use high-temperature water without mixing water, the screw 41 is rotated to move the stop lever 42 to the position of the core 22, so that the memory spring cannot stretch and retract due to temperature change, and high-temperature water outlet is realized without mixing water, thereby being more beneficial to improving the requirement of the user on the diversity of water temperature.
In one embodiment of the present application, as shown in fig. 2, in the case that the requirement of reducing the temperature of the water outlet cannot be met by mixing cold water and hot water, in order to more accurately regulate the temperature, the gas water heater may further include an electric heating module 500, where the electric heating module 500 is disposed between the water outlet pipe 102 and the heat exchanger 300; alternatively, the electric heating module 500 is disposed between the water inlet pipe 101 and the heat exchanger 300. The electric heating module 500 is disposed between the water outlet pipe 102 and the heat exchanger 300 as an example
Specifically, the burner can be assisted in heating water by configuring the electric heating module 500. After the gas water heater is turned off and started again, the electric heating module 42 is electrified to heat, and then the burner 2 is started again; and, the electric heating module 42 is turned off again after the burner 2 is started.
After water is turned on again after water is turned off, the electric heating module 500 is started, and the water flowing through the electric heating module 500 is heated. Specifically, when water is restarted, the water temperature of the water stored in the heat exchanger 300 is relatively high, and is limited by the minimum heating power of the burner 200, if the water in the heat exchanger 300 is directly heated, the water outlet temperature is too high, and the water temperature output after the water outlet temperature control module 400 regulates the flow is still too high. For this reason, when water is restarted, the water flowing out of the heat exchanger 300 is first heated by the electric heating module 500 to reduce the temperature adjustment burden at the electric heating module 500. Meanwhile, the situation that the water temperature is low due to the fact that the burner is not started can be avoided.
After the hot water stored in the heat exchanger 300 flows out, the gas water heater starts the burner 200 and turns off the electric heating module 500. Specifically, after water is turned off, water is turned on again for a certain period of time, and hot water stored in the heat exchanger 300 is output, so that cold water flows into the heat exchanger 300 again. At this time, the burner 200 may be started to heat the heat exchanger 300 for normal hot water supply. Correspondingly, the electric heating module 500 can be powered off to stop working.
The above embodiments are only for illustrating the technical solution of the present application, and are not limiting; although the application has been described in detail with reference to the foregoing embodiments, it will be apparent to one skilled in the art that modifications may be made to the technical solutions described in the foregoing embodiments, or equivalents may be substituted for some of the technical features thereof; such modifications and substitutions do not depart from the spirit and scope of the corresponding technical solutions.
