Description

Technical Field

[0001] The utility model relates to the technical field of kitchen equipment, and more specifically to gas water heaters. Background Art

[0002] A gas water heater, also known as a gas water boiler, refers to a gas appliance that uses gas as fuel and transfers heat to cold water flowing through a heat exchanger through combustion heating to achieve the purpose of preparing hot water.

[0003] Existing gas water heaters are merely water heating devices and are unable to detect water quality. Water quality in the same area often varies at different times, especially when water source treatment or tap water pipeline maintenance is carried out in the area, which is likely to cause a sudden deterioration of the water quality in the area. When water of poor quality flows into the water circuit system of the gas water heater, it is likely to cause scaling in the pipeline of the water circuit system. Therefore, there is a need to detect the water quality of the water flowing into the water circuit system to determine whether it is necessary to temporarily shut off the water inlet or whether there is a need to add a water purification device. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a gas water heater that can detect and display the water quality of the water in the water circuit system to facilitate users to observe the water quality, aiming at the deficiencies of the existing technology.

Specific Embodiment

[0042] The following specifically exemplifies the present invention in combination with embodiments:

[0043] Embodiment:

[0044] A gas water heater, as shown in the appended Figure 1 to the appended Figure 6 figures, includes a housing 1 and a water circuit system disposed within the housing 1.

[0045] In this embodiment, the housing 1 includes a bottom case 1a and a front panel 1b. The bottom case 1a has a receiving cavity with an opening on one side. The water circuit system is installed in the receiving cavity of the bottom case 1a, and the front panel 1b is fixedly connected to the bottom case 1a, for example, by screws, to cover the opening of the receiving cavity, forming an outer shell with the water circuit system installed inside.

[0046] The water circuit system mainly includes a water supply pipe 2 for water circulation, which is divided into: an inlet pipe 2.1 having an inlet for water to flow in, an outlet pipe 2.3 having an outlet for water to flow out, and a connecting pipe 2.2 connecting the inlet pipe 2.1 and the outlet pipe 2.3.

[0047] Among them, the connecting pipe 2.2 is generally coiled around a heat exchanger 6 inside the housing 1. When the water heater operates, gas burns in the heat exchanger 6 to form a high temperature. Cold water enters the water supply pipe 2 from the inlet pipe 2.1. When flowing through the connecting pipe 2.2, the high temperature formed by the heat exchanger 6 heats the water to form hot water, and the hot water flows from the connecting pipe 2.2 to the outlet pipe 2.3 and then is discharged.

[0048] The water quality in the same area often varies at different times. Especially when water source treatment or water pipe maintenance is carried out in this area, it is easy to cause the sudden deterioration of the water quality in this area; when water with poor quality flows into the water circuit system of the gas water heater, it is easy to cause scale formation in the pipeline of the water circuit system.

[0049] Based on this, as shown in the appended Figure 2 to the appended Figure 5 figures, in this embodiment, a water quality monitoring device 4 is provided in the water supply pipe 2 of the water circuit system to detect and display the water quality.

[0050] Specifically, as shown in the appended Figure 3 and the appended Figure 6 figures, the water quality monitoring device 4 in this embodiment includes: a water quality sensor 4.1 for detecting the water quality of the water in the water supply pipe 2, and a display screen 4.2 electrically connected to the water quality sensor 4.1. The display screen 4.2 is configured to: receive the water quality value detected by the water quality sensor 4.1 and display the water quality situation.

[0051] Among them, the water quality sensor 4.1 is preferably a TDS water quality sensor for detecting the TDS value (total dissolved solids) of the incoming water. The display screen 4.2 is configured to: receive the TDS value detected by the water quality sensor 4.1 and display the water quality condition based on the TDS value.

[0052] In one case, the display screen 4.2 is configured to directly display the detected TDS value. The water quality condition can be directly observed by looking at the TDS value displayed on the display screen 4.2 to achieve the display of the water quality condition.

[0053] In another case, the display screen 4.2 is configured to: receive the TDS value and set multiple regional values. For example, the first region is set to 0 to 100 ppm, the second region is set to 100 to 300 ppm, and the third region is set to greater than 300 ppm. When the received TDS value is in the first region, the display screen 4.2 displays that the water quality is excellent; when the received TDS value is in the second region, the display screen 4.2 displays that the water quality is good; when the received TDS value is in the third region, the display screen 4.2 displays that the water quality is poor.

[0054] Among them, both the water quality sensor 4.1 and the display screen 4.2 can be electrically connected to the main board of the gas water heater and powered by the main board.

[0055] However, in this way, after the gas water heater is filled with water but before it is powered on, it is impossible to observe the incoming water quality to determine whether it is suitable for power-on heating.

[0056] Therefore, the water quality monitoring device 4 in this embodiment preferably further includes: an independently arranged battery 4.3; the battery 4.3 is preferably arranged independently of the power cord and the main board of the gas water heater. Moreover, both the water quality sensor 4.1 and the display screen 4.2 are electrically connected to the battery 4.3 and powered by the battery 4.3. It is realized that the water quality monitoring device 4 can continuously and stably detect and display the water quality whether the gas water heater is turned on or off.

[0057] At the same time, considering that if the display screen 4.2 is installed on the surface of the housing 1, not only a relatively long connecting wire is required to electrically connect the display screen 4.2 and the water quality sensor 4.1, forming a complicated wiring structure; moreover, when the housing 1 is disassembled, it is easy to pull the connecting wire and cause it to break.

[0058] Therefore, as shown in the attached Figure 1 In the figure, the display screen 4.2 is arranged inside the housing 1 and preferably close to the water supply pipeline 2 to avoid the above-mentioned wiring situation. At the same time, a window 1.1 is provided on the housing 1, and the window 1.1 is arranged opposite to the display screen 4.2 of the water quality monitoring device 4. For example, in the attached Figure 1As shown in the figure, in this embodiment, a window 1.1 is provided on the panel 1b opposite to the display screen 4.2. Through the window 1.1, the water quality displayed on the display screen 4.2 can be directly observed from outside the housing 1. That is, without disassembling the panel 1b, the water quality situation displayed on the display screen 4.2 can be observed more quickly and directly from outside the housing 1.

[0059] Further considering that after being heated by the heat exchanger 6, some heat-soluble impurities or bacteria in the water are easily eliminated, reducing the impact on the detection of the TDS value. Therefore, the water quality sensor 4.1 in this embodiment is preferably arranged in the outlet pipe 2.3 of the water supply pipe 2 to detect the water quality of the water treated by heating in the outlet pipe 2.3, so as to obtain a more accurate and required water quality detection result.

[0060] Further, as shown in the attached Figure 2 to the attached Figure 6 figure, the outlet pipe 2.3 includes: two outlet pipes 2.31 arranged at intervals, and a water tank body 2.32 connecting the two outlet pipes 2.31. The water tank body 2.32 is arranged opposite to the window 1.1, and the water tank body 2.32 has: a water flow chamber 2.321 for connecting the two outlet pipes 2.31.

[0061] The diameter of the water flow chamber 2.321 is preferably larger than the diameter of the outlet pipe 2.31. The water quality sensor 4.1 is preferably placed in the water flow chamber 2.321 to detect the water quality, and the display screen 4.2 is also preferably fixed on the side of the water tank body 2.32 facing the window 1.1 by, for example, screws or glue, and the battery 4.3 is also preferably fixed on the water tank body 2.32 by, for example, screws or glue. In this way, the water quality sensor 4.1 can be placed in the larger-capacity water flow chamber 2.321 to sense the water quality of a larger amount of water and obtain a more accurate detection effect.

[0062] Furthermore, considering the replacement requirement of the water tank body 2.32. In this embodiment, the water tank body 2.32 is preferably detachably fixed between the two outlet pipes 2.31.

[0063] Specifically, in this embodiment, for each outlet pipe 2.31, an insertion pipe 2.322 is provided on the water tank body 2.32 to match the outlet pipe 2.31, and the outlet pipe 2.31 is inserted into the insertion pipe 2.322 to communicate with the water flow chamber 2.321.

[0064] That is, as shown in the attached Figure 3 to the attached Figure 6As shown, at the upper end of the water tank body 2.32, there is an insertion pipe 2.322 disposed to match the upper water outlet pipe 2.31 above. The upper water outlet pipe 2.31 is inserted into the insertion pipe 2.322 at the upper end of the water tank body 2.32 and is communicated with the water flow cavity 2.321. At the lower end of the water tank body 2.32, there is an insertion pipe 2.322 disposed to match the lower water outlet pipe 2.31 below. The lower water outlet pipe 2.31 is inserted into the insertion pipe 2.322 at the lower end of the water tank body 2.32 and is communicated with the water flow cavity 2.321. Thus, the two water outlet pipes 2.31 are connected through the water flow cavity 2.321.

[0065] Meanwhile, any insertion pipe 2.322 and the water outlet pipe 2.31 inserted into the insertion pipe 2.322 are detachably connected through a buckling structure, so that the water tank body 2.32 is detachably fixed between the two water outlet pipes 2.31.

[0066] In this embodiment, as shown in the attached Figure 3 to the attached Figure 6 figure, the buckling structure includes: a first flange 2.323 disposed on the outer periphery of the insertion pipe 2.322, a second flange 2.311 disposed on the outer periphery of the water outlet pipe 2.31, and a detachable clip 2.33.

[0067] Among them, the first flange 2.323 and the second flange 2.311 are disposed to match each other, so that when the water outlet pipe 2.31 is inserted into the insertion pipe 2.322, the second flange 2.311 fits snugly on the first flange 2.323. The clip 2.33 is configured to: limit the first flange 2.323 and the second flange 2.311 from fitting together, so that the insertion pipe 2.322 and the water outlet pipe 2.31 inserted into the insertion pipe 2.322 are detachably connected.

[0068] Furthermore, as shown in the attached Figure 5 figure, the clip 2.33 in this embodiment includes: two clamping rings 2.331 disposed at intervals, and the two clamping rings 2.331 are respectively disposed on both sides of the water outlet pipe 2.31; it also includes a connecting arm 2.332 connecting the two clamping rings 2.331.

[0069] Among them, each clamping ring 2.331 is provided with a clamping hole 2.333, and the mutually fitting first flange 2.323 and second flange 2.311 are jointly installed in the clamping hole 2.333, so as to be as shown in the attached Figure 2 and the attached Figure 3As shown in the figure: The first flange 2.323 and the second flange 2.311 are tightly fitted together. Moreover, the connecting arm 2.332 is elastic so that it can: make the clip 2.33 in a detachable state by driving the connecting arm 2.332 to undergo an elongation deformation. That is, by bending the two clamps 2.331 outwards to drive the connecting arm 2.332 to elongate, the first flange 2.323 and the second flange 2.311 are disengaged from the clamping hole 2.333, and then the clip 2.33 can be disassembled, enabling the water outlet pipe 2.31 to be pulled out from the insertion pipe 2.322, and the water tank body 2.32 can be disassembled.

[0070] A seal 2.34 can also be provided between the water outlet pipe 2.31 and the inner wall of the water tank body 2.32 to fill the gap between the water outlet pipe 2.31 and the inner wall of the water tank body 2.32. The seal 2.34 is preferably a sealing ring made of silicone or rubber, etc. By filling it into the gap between the water outlet pipe 2.31 and the inner wall of the water tank body 2.32, sealing can be achieved.

[0071] On the above basis, further considering that when the gas water heater is working normally, on the one hand, hot water is likely to directly impact the water quality sensor 4.1, which is likely to damage the water quality sensor 4.1; on the other hand, the water flow drains quickly, and the water quality sensor 4.1 cannot stably and accurately detect the water quality.

[0072] Therefore, as shown in the appendix Figure 6 As shown in the figure, a baffle 2.324 can also be additionally provided in the water flow chamber 2.321 of the water tank body 2.32. A receiving cavity is formed at an interval between the baffle 2.324 and the side wall of the water flow chamber 2.321, and the water quality sensor 4.1 is placed in this receiving cavity to detect the water quality. Moreover, the upper end of the baffle 2.324 is connected to the position near the insertion pipe 2.322 on the upper end wall of the water flow chamber 2.321 (at this time, the insertion pipe 2.322 at the upper end of the water tank body 2.32 serves as the water inlet of the water flow chamber 2.321, and the insertion pipe 2.322 at the lower end serves as the water outlet of the water flow chamber 2.321); the lower end extends downward and forms an outlet for the water in the receiving cavity to flow outwards at an interval from the side wall of the water flow chamber 2.321. In order to slow down the impact while better detecting the water quality, a number of water passing holes 2.325 for the water flowing into the water flow chamber 2.321 to flow into the receiving cavity are preferably provided at the upper end portion of the baffle 2.324.

[0073] Furthermore, as shown in the appendix Figure 6As shown in the figure, in the vertical direction from top to bottom, the baffle 2.324 is preferably bent and extended so that the side of the baffle 2.324 facing away from the accommodation cavity is a curved surface structure, which guides the water to flow smoothly through the drainage surface of the water flow cavity 2.321, ensuring smooth water output from the water supply pipeline 2. At the same time, the lower end of the baffle 2.324 is bent and placed below the water quality sensor 4.1, so as to prevent the water entering the accommodation cavity from the water passing hole 2.325 from flowing out quickly, enabling the water quality sensor 4.1 to detect the water quality of the water with reduced flow rate in the accommodation cavity, so as to obtain more stable and accurate detection results.

[0074] The above are only the preferred embodiments of the present invention, and do not limit the scope of the present invention. In addition, the terms "vertical", "horizontal", "front", "rear", etc. mentioned in the embodiments of the present invention indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, or the orientation or positional relationship in which the product is usually placed during use.
