When the water softener and the gas water heater are integrated, the actual installation space cannot be too large, and correspondingly, the size of the whole machine cannot be too large, so that a small distance needs to be kept between the gas water heater and the water softener. However, since the gas water heater generates high-temperature smoke when operating, if the distance between the gas water heater and the water softener is small, the high-temperature smoke may be radiated to a component, such as a resin tank, of the water softener, which does not endure high temperature, thereby affecting the reliability of the water softener when operating.

In some cases, it may be considered to reduce the height of the resin tank so as to avoid a high temperature region where high temperature fumes are radiated. However, the volume of the resin tank also has specific technical requirements for the water softener. At present, the volume of the resin tank generally needs 3L to ensure the normal working performance of the water softening device, and simultaneously, the use requirement of a user is met. That is, it is not possible to avoid the high temperature region simply by reducing the height of the resin tank at present.

The integrated water system that provides in this application specification can guarantee the reliability of the respective work of integrated water softening installation and gas hot water system, especially avoids the heat of the high temperature flue gas that gas hot water system during operation produced to influence the reliability of water softening installation resin tank.

Referring to fig. 1 to 5 in combination, in the embodiments of the present disclosure, an integrated water system is provided, which may include: a housing 100 having a predetermined volume; a gas-fired water heating apparatus 200 disposed inside the case 100; a water softening device 300 communicated with a water path of the gas water heating apparatus 200, the water softening device 300 including a resin tank 310; and a heat insulation mechanism 400 provided between the gas water heater 200 and the resin tank 310.

In the present embodiment, the integrated water system may be a system in which the gas water heater 200 and the water softening device 300 communicated with the water path of the gas water heater 200 are installed in the case 100 having a predetermined volume. Wherein the water softening device 300 is provided with a resin tank 310, and the resin tank 310 is a heat-labile member. Generally, the maximum heat resistant temperature of the resin tank 310 is 50 degrees celsius, and when the temperature of the environment where the resin tank 310 is located exceeds the maximum heat resistant temperature, the reliability of the use of the resin tank 310 is directly affected, and the service life of the water softener 300 is further affected.

The gas water heater 200 generates high-temperature flue gas during operation, and a high-temperature region is formed in a region (including but not limited to the fume collecting hood 250, a smoke pipe communicated with the fume collecting hood 250, the fan 240 communicated with the fume collecting hood 250, etc.) through which the high-temperature flue gas flows. The temperature of the high temperature zone is very high, exceeding the maximum heat-resistant temperature of the resin tank 310. In order to prevent the high temperature generated when the gas water heater 200 operates from adversely affecting the resin tank 310, a heat insulation mechanism 400 is provided between the resin tank 310 and the gas water heater 200, and the heat insulation mechanism 400 can greatly reduce the adverse effect of the high temperature generated when the gas water heater 200 operates on the resin tank 310, thereby ensuring the respective operational reliability of the integrated water softener 300 and the gas water heater 200.

The present application will be described in detail below with reference to specific embodiments.

In one embodiment, the gas water heater 200 and the water softener 300 are arranged side by side along the length direction x of the housing 100.

In the present embodiment, the casing 100 may have a hollow structure of a rectangular parallelepiped as a whole, and the case 100 is mainly illustrated as a rectangular parallelepiped type with a hollow structure, but it is needless to say that the casing 100 may have other shapes, and the present invention is not limited to this. The volume of the housing 100 may vary according to the actual installation environment, the specific volume of the gas water heater 200 and the water softener 300, and the numerical values thereof are not specifically limited in this application.

As shown in fig. 1 and 2, the housing 100 has a length direction x, a width direction z, and a height direction y opposite to each other. Generally, the dimension in the longitudinal direction x is larger than the dimension in the width direction z. In order to reduce the volume of the housing 100 as much as possible and to make the best use of the internal space of the whole device, the gas water heater 200 and the water softener 300 may be arranged side by side along the length direction x of the housing 100.

In the present embodiment, the gas water heater 200 includes, in the height direction y: a smoke collection hood 250 in communication with the flue outlet, a heat exchanger 230, a combustor assembly 220, and a valve distributor assembly 210. Of course, the gas-fired water heating apparatus 200 may further include other components such as a fan 240.

In the present embodiment, the smoke collecting hood 250 serves to guide smoke generated by combustion toward the smoke pipe. Specifically, the fume collecting hood 250 may be located at the top of the whole integrated water system, and the lower side of the fume collecting hood may be in sealing engagement with the housing, and the upper side of the fume collecting hood may be provided with an outlet in engagement with the fume pipe.

In the present embodiment, combustor assembly 220 includes a combustion chamber and a burner located within the combustion chamber. Wherein, the combustor is used for mixing and burning gas and air. When ignited, the high temperature flue gas generated by the mixed combustion of the fuel gas and the air can be used for heating the water flow in the heat exchanger 230. Specifically, the burner can comprise a plurality of fire rows which are arranged in parallel, and the plurality of fire rows can be arranged on the mounting seat. Of course, the structure, form, etc. of the burner may be different according to the actual use scenario, and the application is not limited in this respect.

In this embodiment, the combustion chamber may be enclosed at the periphery of the burner. In particular, the combustion chamber may be in the form of a frame open at both ends. The burner may be disposed entirely within the combustion chamber or partially within the combustion chamber, and the application is not limited thereto.

In the present embodiment, water to be heated flows through the heat exchanger 230. Specifically, the heat exchanger 230 may be in the form of a heat exchange tube, one end of which is in communication with the inlet pipe and the other end of which is in communication with the outlet pipe. Of course, the shape, configuration, etc. of the heat exchanger 230 may be different according to the actual usage scenario, and the application is not limited thereto.

The fan 240 is used to provide the driving force for the airflow. Specifically, the installation location of the blower 240 may vary depending on its particular form, for example, when the blower 240 is an upper draft blower, the blower 240 may be disposed between the fume collecting hood 250 and the heat exchanger 230, and when the blower 240 is a lower draft blower, it may be disposed at the lower side of the firebox assembly 220.

Specifically, the lower blower fan 240 may be installed at a lower portion of the burner, and the blower fan 240, the burner, and the heat exchanger 230 are sequentially disposed from bottom to top. Positive pressure is created within the combustion chamber of the integrated water system. In addition, the fan 240 may also be in the form of an updraft fan. When the fan 240 is an upper exhaust fan, the burner, the heat exchanger 230, the upper exhaust fan, the smoke collection cover 250, and the like are sequentially arranged in the flow direction of the smoke. Specifically, the upper exhaust fan 240 may be installed at an upper portion of the burner, and the burner, the heat exchanger 230, and the fan 240 are sequentially disposed from bottom to top. Negative pressure is formed in a combustion chamber of the integrated water system, and the internal pressure of the integrated water system is smaller than the external pressure.

In one embodiment, to further improve the overall internal space utilization, the heat exchanger 230, the combustor assembly 220, and the air valve distributor assembly 210 are mounted with a 90 ° rotation in the height direction y.

In the present embodiment, since the gas water heater 200 and the water softener 300 are arranged side by side along the longitudinal direction x of the housing 100, in order to prevent the housing 100 from being excessively large in width, the components of the gas water heater 200 having a large width and a relatively small height may be arranged side by rotating them by 90 °. Specifically, the components requiring a side layout include: heat exchanger 230, combustor assembly 220, and air valve distributor assembly 210.

In order to control the length dimension of the housing 100 as much as possible, the distance between the gas water heater 200 and the water softener 300 is between 5 mm and 100 mm for the embodiment that the gas water heater 200 and the water softener 300 are arranged side by side along the length direction x of the housing 100.

Wherein, after the interval between the gas water heater 200 and the water softener 300 is 5 mm, a minimum safety distance can be ensured between the parts of the gas water heater 200 and the water softener 300. The minimum safe distance mainly ensures that the components between the gas water heater 200 and the water softener 300 cannot generate abnormal sounds such as vibration massage and the like due to contact within the installation dimensional tolerance. When the distance between the gas water heater 200 and the water softener 300 exceeds 100 mm, the length of the housing 100 is increased more, which is not favorable for controlling the length of the housing 100.

In one embodiment, the distance from the fume collecting hood 250 to the resin tank 310 is between 10 mm and 50 mm.

In the present embodiment, the gas water heater 200 generally has an irregular shape in which the fume collecting cover 250 in a high temperature region is a member closest to the resin tank 310. In order to satisfy both the length dimension of the housing 100 and the reliability, i.e., to ensure the reliability of the water softening device 300 while the length dimension of the housing 100 of the entire machine satisfies the installation requirement, the distance from the fume collecting hood 250 to the resin tank 310 may be between 10 mm and 50 mm.

Particularly, in order to ensure the reliability of the water softening device 300, when the heat insulation mechanism 400 provided between the gas hot water device 200 and the resin tank 310 is a solid structure, the distance from the hood 250 to the resin tank 310 needs to be in consideration of the installation size and the solid size of the heat insulation mechanism 400, and thus the distance from the hood 250 to the resin tank 310 is between 10 mm and 50 mm. Of course, the distance between the smoke collecting hood 250 and the resin tank 310 may be adjusted according to the form of the heat insulation mechanism 400, generally, when the heat insulation mechanism 400 is a solid structure, such as a baffle, the thickness of the baffle is not too thick (generally several millimeters), and in the present embodiment, the distance between the smoke collecting hood 250 and the resin tank 310 is not more than 50 millimeters. When the distance between the fume collecting cover 250 and the resin tank 310 exceeds 50 mm, the temperature of the fume collecting cover 250 radiated to the resin tank 310 may be lower than or close to the maximum heatproof temperature of the resin tank 310, and the necessity of providing the heat insulation mechanism 400 may be greatly reduced.

In this embodiment, the heat insulation mechanism 400 may include any one or a combination of the following: a baffle plate with a predetermined thickness, an air cooling hole arranged on the shell 100, a heat insulation cavity enclosed outside the resin tank 310, and a heat insulation piece covered outside the resin tank 310. In addition, the heat insulation mechanism 400 may be in another way or combination way capable of isolating the heat generated by the high-temperature flue gas from the resin tank 310. Several forms of the thermal isolation mechanism 400 are described below in conjunction with the figures.

Referring to fig. 3, 4 and 5 in combination, in one embodiment, the heat insulation mechanism 400 includes a baffle having a predetermined thickness, and the baffle has a predetermined distance from the gas hot water apparatus 200 or the water softening apparatus 300.

In this embodiment, the thermal insulation mechanism 400 may include a baffle having a predetermined thickness. High temperature resistant panel beating material can be chooseed for use to this baffle. The baffle may be mounted to the housing 100 by a removable connection. For example, it may be fixed to the housing 100 by means of a bolt connection. The thickness of the baffle is not specifically limited herein, and the baffle is fixed to the housing 100 only by ensuring sufficient strength and not easily deformed. The baffle has opposite top and bottom ends 401 and 402, and at least one convex hull 410 may be provided on the baffle body from the top end 401 to the bottom end 402 to enhance the strength of the baffle.

After the baffle is installed on the housing 100, a gap with a predetermined distance is formed between the baffle and the gas water heater 200 and the water softener 300, so that on one hand, high temperature generated by the gas water heater 200 can be prevented from being transferred to the water softener 300 in a heat transfer manner; on the other hand, the heat in the high temperature region of the gas water heater 200 can be blocked by the baffle plate, and the influence of the high temperature on the resin tank 310 can be reduced as much as possible. In addition, after the air is between the gas water heater 200 and the baffle, the baffle is favorable for realizing diversion and temperature reduction.

Specifically, the first air-cooling hole 101 is provided in the housing 100 adjacent to the fume collecting cover 250 in the height direction Y. When the first air-cooling hole 101 is provided, the air entering from the first air-cooling hole 101 can take away the heat near the smoke collecting hood 250, so that the influence of the heat generated in the high temperature region near the smoke collecting hood 250 on the resin tank 310 can be further reduced. The specific form of the first air-cooling hole 101 may include a plurality of holes arranged at intervals, and the plurality of holes may be arranged in an array. Of course, the first air-cooling hole 101 may also be in other forms, and the application is not limited in this respect.

As shown in fig. 1, in one embodiment, a baffle divides the housing 100 into a first region for mounting the gas water heater 200 and a second region for mounting the water softener 300 along the length direction X, and the first air cooling hole 101 is disposed at the first region and adjacent to the baffle. When the first air cooling hole 101 located in the first area is disposed close to the baffle, the cold air entering the casing 100 from the external environment through the first air cooling hole 101 can guide the heat of the high temperature area to the burner through the baffle for the first time.

It should be noted that: for the scene that the air cooling hole is arranged at the bottom of the shell 100, a large amount of air enters from the bottom and then directly enters the combustion chamber along the middle of the shell 100, the air flow distribution is mainly concentrated in the middle, the air close to the two side wall surfaces is little, and the air volume distribution is uneven.

After combining first forced air cooling hole 101 on the basis of baffle, this baffle not only has thermal-insulated function, in addition, and it still has the water conservancy diversion function, combines the position setting of this first forced air cooling hole 101, can flow the air that first forced air cooling hole 101 flowed into along baffle top-down earlier, then get into in the combustion chamber again. The air cooling flow field is changed by adjusting the air flow path, so that the heat of a high-temperature area can be taken away, and the air entering a combustion chamber can be distributed more uniformly; furthermore, the air entering the combustion chamber can be preheated.

Further, the second air cooling hole 102 is provided in the housing 100 near the combustor assembly 220 in the height direction Y, and the second air cooling hole 102 is provided near the baffle in the length direction X.

To further ensure a stable inflow of a sufficient amount of air into the combustion chamber, the baffle has opposite top and bottom ends 401 and 402 in the height direction Y, the bottom end 402 being located no higher than the second air-cooling hole 102.

When the bottom end 402 of the baffle extends to be at least flush with the second air cooling hole 102, the baffle can be used for directly guiding the air from the second air cooling hole 102 to the combustion chamber, and the air entering through the second air cooling hole 102 and the air entering through the first air cooling hole 101 can be guided to the combustion chamber by utilizing the guide effect of the baffle to be mixed with the fuel gas for combustion. Specifically, the second air cooling hole 102 may also include a plurality of holes arranged at intervals, and the plurality of holes may be arranged in an array. Of course, the second air cooling hole 102 may also be in other forms, and the application is not limited in this respect.

In one embodiment, the gas-fired water heating apparatus 200 is provided with an upper suction fan, and the baffle has opposite top and bottom ends 401 and 402 in the height direction Y, and the bottom end 402 is located not higher than the resin tank 310.

In this embodiment, when the gas water heater 200 employs an upper exhaust fan, a negative pressure is formed in the housing 100 after the fan 240 is started. In order to further improve the reliability of the resin tank 310 and prevent the gas-fired water heater 200 from being affected by special conditions (such as fire spill of the combustion chamber caused by accidental blockage of the smoke pipe), the bottom end 402 of the baffle plate extends at least to the bottom end 402 of the resin tank 310, so that the resin tank 310 is protected in all aspects and the reliability of the resin tank in operation is ensured.

In addition, in the description of the present application, "a plurality" means two or more unless otherwise specified.

The above embodiments in the present specification are all described in a progressive manner, and the same and similar parts among the embodiments may be referred to each other, and each embodiment is described with emphasis on being different from other embodiments.
