The following description will be made with reference to a water storage type water heater in a bath product as a specific embodiment.

Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a water heating apparatus 100 according to the present invention, and fig. 2 is an exploded schematic structural diagram of the water heating apparatus according to the present invention. The hot water device illustrated in fig. 1 includes a housing 110 having an inner container mounted therein, which is not shown. In fig. 2, the outer shell is provided with a water inlet 111 and a water outlet 112, which are respectively in fluid communication with the inner container.

The constant temperature control device 200 and the filter device 300 are installed on the shell, and the filter filters the raw water from the outside and then flows into the inner container through the constant temperature control device. The inner container heats the filtered water, then the heated water flows into the thermostatic control valve, and the filtered raw water and the hot water in the thermostatic control valve are mixed into warm water to be supplied.

The components of the water heating apparatus will be described in detail below, and for convenience of description, the up and down directions are introduced, and the specific up and down directions are oriented as shown in fig. 2.

Constant temperature control device

Referring to fig. 3 to 5, fig. 3 is a schematic view of an overall structure of the thermostat control device, fig. 4 is an exploded schematic view of the thermostat control device, and fig. 5 is a partial schematic view of the thermostat control device.

As shown in fig. 3, the thermostatic control device 200 has a valve body 210, which is opened with four ports, namely, a filtered water inlet 211, a water supply outlet 212, a hot water inlet 213, and a mixed water outlet 214. The water filtering inlet is communicated with the filter fluid, and then raw water filtered by the filter enters the valve body through the water filtering inlet. The water supply outlet is communicated with the water inlet on the shell, and the liquid in the valve body flows into the inner container through the water inlet to be heated. The water supply outlet is communicated with the water outlet on the shell, and hot water heated in the inner container flows into the valve body through the water outlet. After the hot water in the valve body is mixed with the filtered raw water, the obtained mixed water with proper temperature is discharged from the mixed water outlet and is provided for users.

Referring to fig. 6 and 7 in combination, fig. 6 is a schematic interface diagram of the thermostat control device in fig. 3, and fig. 7 is a partially enlarged view of a portion a in fig. 6.

As shown in fig. 6 and 7, a water filtering chamber 220, a hot water chamber 230 and a water mixing chamber 240 are provided in the valve body 210. The water filtering cavity 220 is in fluid communication with the water filtering inlet 211 and the water supply outlet 212, and is used for accommodating the filtering raw water flowing in from the water filtering inlet, and the filtering raw water in the water filtering cavity can flow into the inner container through the water supply outlet to be heated. The hot water chamber 230 is in fluid communication with the hot water inlet 213, and hot water heated by the inner container is discharged from the water outlet and then flows into the hot water chamber through the hot water inlet.

The flow control valve is arranged in the water mixing cavity and used for simultaneously controlling the communication opening degree of the water filtering cavity and the water mixing cavity and the communication opening degree of the hot water cavity and the water mixing cavity. Referring to fig. 7, the water filtering chamber 240 is communicated with the water mixing chamber 240 through a first water passing opening 250, and the opening degree of the first water passing opening is controlled by a flow regulating valve; the hot water chamber 230 is communicated with the water mixing chamber 240 through a second water passing opening 260, and the opening degree of the second water passing opening is also controlled by a flow regulating valve. Therefore, when a user adjusts the temperature of the mixed water discharged from the mixed water outlet, the mixed water temperature in the mixed water cavity is adjusted according to the proportion of the cold water (filtered raw water) and the hot water flowing into the mixed water cavity, and the proportion of the cold water and the hot water is determined according to the opening degrees of the first water passing port and the second water passing port. Therefore, when the user adjusts the mixed water to discharge water at a certain temperature, the opening degrees of the first water passing port and the second water passing port are correspondingly determined through the flow regulating valve. The flow regulating valve regulates the opening degrees of the first water passing opening and the second water passing opening to be opposite, namely the flow regulating valve can correspondingly reduce the opening degree of the second water opening while expanding the opening degree of the first water opening, and otherwise, the opening degree of the second water opening is expanded.

Flow regulating valve

Referring to fig. 4, 5 and 7, the flow control valve includes a plug 400, which is substantially in the shape of a hub and has an upper opening and a lower opening. The central axis of the plug body is fitted with a micro-control valve 500, the upper and lower ends of which protrude from the top and bottom of the plug body. The upper end of the micro-control valve is sleeved with a spring 600, the lower end of the spring is abutted against the upper part of the plug body (specifically, the micro-control valve), and the upper end of the spring is abutted against the valve body.

The flow control valve further comprises an adjusting knob 700 rotatably fixed at the bottom of the valve body 210, and an internal thread is arranged inside the adjusting knob. An adjusting rod 800 is arranged between the plug body and the adjusting knob, and external threads are arranged on the adjusting rod, so that the adjusting knob is matched with the adjusting rod. And, when the adjusting knob 700 is rotated in a circumferential direction (since the adjusting knob is rotatably fixed to the valve body, the adjusting knob does not move up and down when rotated), the adjusting lever 800 is urged to move up or down by the screw. Meanwhile, the lower end of the micro control valve 500 abuts against the upper end of the adjustment rod 800, and therefore, when the adjustment rod 800 is controlled to move upwards, the plug body 400 compresses the spring 600 to move upwards; when the control adjustment lever 800 moves downward, the plug body 400 releases the spring 600 to move downward.

With continued reference to fig. 7, the valve body has a water filtering chamber 220, a hot water chamber 230 and a water mixing chamber 240, but when the plug 400 is installed in the water mixing chamber 240, the plug is tightly attached to the inner wall of the water mixing chamber, so that the inner cavity of the plug replaces most of the space of the water mixing chamber to provide water mixing. At this time, the lower end opening of the plug body is in fluid communication with the first water gap 250, the upper end opening of the plug body is in fluid communication with the second water gap 260, and the inner cavity of the plug body is in fluid communication with the mixed water outlet. Therefore, it is easy to understand that, when a user wants to reduce the outlet water temperature of the mixed water outlet, the adjusting knob 700 drives the adjusting rod 800 to push the plug 400 upwards, so as to reduce the opening degree of the second water passing port 260, reduce the hot water in the hot water chamber 230 from entering the mixed water chamber 240, increase the opening degree of the first water passing port 250, increase the filtered raw water (cold water) in the water filtering chamber 220 from entering the mixed water chamber 240, and further reduce the mixed water temperature of the mixed water chamber. On the contrary, then move down through adjust knob control cock body, the aperture of the mouth of a river is crossed to the increase second, increases the hot water entering of hot water intracavity and mixes the water intracavity, simultaneously, has reduced the aperture of first mouth of a river, has reduced the filtration raw water (cold water) entering of drainage intracavity and has mixed the water intracavity, and then improves the temperature through mixing the water intracavity exhaust muddy water.

Micro-control valve

Referring to fig. 4 and 7, the flow control valve further includes a micro control valve 500 fixed to the plug 400, and paraffin is filled in the micro control valve. When the mixed water temperature in the water mixing cavity 240 becomes low, the paraffin shrinks, the spring 600 extends to push the micro-control valve 500 and the plug 400 downwards for micro-movement, so that the opening degree of the first water passing opening 250 is reduced, and cold water (filtered raw water) entering the water mixing cavity is reduced; meanwhile, the opening degree of the second water passing port 260 is increased, and the hot water is increased to enter the water mixing chamber 240. When the temperature of mixed water in the water mixing cavity becomes high, the paraffin expands to pull the micro-control valve and the plug body to compress the spring to move upwards slightly, so that the opening degree of the second water passing opening is reduced, and hot water is reduced to enter the water mixing cavity; meanwhile, the opening degree of the first water passing opening is increased, and cold water (filtered raw water) is added to enter the water mixing cavity.

When the hot water device is used specifically, a user rotates the adjusting knob to adjust the required temperature value, the plug body moves to a certain position according to the adjusting knob, and the opening degree of the first water passing port and the opening degree of the second water passing port are correspondingly determined. Raw water enters the filter 300 from the raw water inlet 312 (shown in fig. 8), is filtered, flows to the filtered water inlet of the thermostatic control device from the filtered water outlet 313 (shown in fig. 8), and then enters the filtered water chamber. Most of the filtered raw water in the water filtering cavity flows to the water inlet of the shell to enter the inner container, and the other part of the filtered raw water in the water filtering cavity enters the water mixing cavity through the first water passing hole to wait for being mixed with hot water. The hot water heated in the inner container flows to a hot water inlet of the constant temperature control device through the water outlet, then enters the hot water cavity, and then enters the water mixing cavity through the second water passing hole to be mixed with the filtered raw water in the water mixing cavity, so that the mixed water with proper temperature is formed. And finally, the mixed water is discharged through the mixed water outlet for users to use. With the use of the water heating device, the temperature of the hot water in the inner container may decrease (if the heating device in the inner container is operated all the time, the temperature of the water may increase), and thus the temperature of the mixed water in the water mixing cavity decreases accordingly. At the moment, the paraffin in the micro-control valve can shrink to drive the micro-control valve and the plug body to slightly move downwards, so that the hot water inlet amount of the water mixing cavity is increased, and meanwhile, the cold water inlet amount is reduced, and therefore the constant water temperature of water discharged from the water mixing cavity is guaranteed.

Filter

Referring to fig. 8 to 10, fig. 8 is an exploded view of a filter, fig. 9 is a structural view of a filter element frame of the filter, and fig. 10 is a sectional view of the filter element frame of fig. 9.

The filter 300 comprises a copper head assembly 310, a filter flask 320, a filter element assembly 330, a screen cover 340 and the like, wherein the filter element assembly 330 comprises a filter screen 331, a filter element framework 332 and the like.

Copper head assembly

Referring to fig. 8, the copper head assembly has a mounting cover 311, a raw water inlet 312, a filtered water outlet 313, and the like. The shape of the mounting cover can be specifically limited according to the shape of the filter flask, and the filter flask is usually round, but also square and other polygonal shapes. The part of the mounting cover, which is connected with the filter flask, is provided with internal threads and is fixed on the filter flask in a threaded connection mode. The outer leakage side surface of the mounting cover is provided with a raw water inlet and a filtered water outlet.

Filter flask

The filter flask 320 is substantially cylindrical, and has one open end and the other closed end without any other passage. In combination with the above copper head assembly, the shape of the two is matched, and the filter flask is arranged in a roughly cylindrical barrel, but the cross section of the filter flask is rectangular or other polygons and the like. The open end of the filter flask is provided with an external thread which is matched with the internal thread of the copper head component.

Filter element assembly

The filter element assembly 330 includes a filter element frame 332 and a filter screen 331, and the filter screen 331 is supported by the filter element frame 332 and located at the periphery of the filter element frame. When the filter element assembly 330 is installed in the accommodating cavity formed by the copper head assembly 310 and the filter flask 320, in combination with fig. 8, the filter element assembly divides the entire accommodating cavity into two parts, one part is a water inlet cavity Q1 (an outer cavity shown by a dotted line circle in fig. 1) located at the outer periphery of the filter screen, and the other part is a filter cavity Q1 (an inner cavity shown by a dotted line circle in fig. 1) located in the filter screen (i.e., in the filter element framework), and the water inlet cavity is communicated with the filter cavity through filter holes in the filter screen. In addition, correspondingly, the raw water inlet 312 of the copper head assembly is communicated with the water inlet cavity Q1 in a fluid mode, and the filtered water outlet 313 of the copper head assembly is communicated with the filtering cavity Q2 in a fluid mode.

In the water filtering process, raw water flows into the water inlet cavity from the raw water inlet, then flows into the filtering cavity after being filtered by the filter screen, and is discharged from the filtered water outlet. It should be noted that, because the raw water inlet and the filtered water outlet of the filter are located at the same end, in the process of filtering and flowing liquid, if the openings on the filter element framework are uniformly distributed, the liquid pressure difference between the inside and the outside of the filter screen is larger near one end of the water outlet, so that the higher the utilization rate of the filter screen is, the faster the dirt is accumulated, and the problem of local blockage of the filter screen is easy to occur. To this problem, this application is solved by improving the filter element skeleton.

Filter element framework

Fig. 9 is a schematic view of the filter cartridge framework 332 of the present application, wherein the filter chamber Q2 is located inside the filter cartridge framework, and one end of the filter chamber is open, and the end with the open end is the water outlet end 3321 of the filter cartridge framework. The above indicated filtered water outlet is in fluid communication with the filter chamber, i.e. by communication with the outlet end. For convenience of description, the opposite ends of the filter element framework are defined, one end is a water outlet end 3321, and the other end is a free end 3322. Particularly, the water permeable area of the filter element framework is gradually increased in the direction from the water outlet end to the free end, and the gradual increase can be continuous or step-shaped. As can be seen from fig. 9 and 10, the water permeable area of the filter element framework increases in a stepwise manner, because the hole area of the circular hole P1 is smaller than that of the rectangular hole P2, and therefore, the opening rate of the partial area of the circular hole is smaller than that of the partial area of the rectangular hole.

In the use process of the filter, the liquid flow rate at the position closer to the water outlet end is higher, so the pressure difference between the inner side and the outer side of the filter screen is higher at the position closer to the water outlet end, and the pressure difference between the inner side and the outer side of the filter screen at the position farther away from the water outlet end is lower. Consequently, under the different great prerequisite of pressure differential value everywhere at filter core skeleton, the utility model provides an among the filter core skeleton, through the area of permeating water that changes filter core skeleton, the regional area of permeating water that sets up and keep away from water outlet department more sets up big more. Thus, the pressure difference near the water outlet end is reduced, while the pressure difference far from the water outlet end is relatively increased. And then, reduce the size difference of the pressure differential value everywhere of filter core skeleton, effectively improve the whole availability factor of filter screen, avoid appearing the problem of local jam.

Further, referring to fig. 9, since the filter element frame is provided with a large number of holes, in order to ensure the supporting strength of the filter element frame, the periphery of the water permeable holes provided on the filter element frame 332 is provided with a convex rib 3323, thereby enhancing the overall strength of the filter element frame. Simultaneously, because the filter screen is supported in the periphery of filter core skeleton, consequently, through the setting of protruding muscle, can separate filter screen and filter core skeleton, the flow of being convenient for liquid.

Further, with continued reference to fig. 9, the free end of the filter element framework is provided with a mounting location 3324 for mounting a magnetic member (not shown). The magnetic member adsorbs metal substances, such as iron, cobalt, nickel and the like, in the filtered water in the filtering cavity during the water filtering process of the filter, thereby improving the filtering quality.

Mounting rack

Referring to fig. 2, a mounting bracket 1000 is fixed to the bottom of the housing, the mounting bracket is provided with at least two mounting positions, and the thermostat 200 and the filter 300 are mounted on the mounting positions of the mounting bracket 1000. The mounting bracket is located on the exterior of the housing so that it can be removed directly when the thermostat or filter needs to be cleaned or replaced. The shape of the mount is not particularly limited, and for example, as shown in fig. 1, the mount is provided as a rectangular frame. In addition, the fixing position of the mounting bracket is not limited to the bottom of the housing, such as both sides, or the front surface.

Electricity-proof cover

Since the thermostat control device and the filter are exposed to the outside of the housing, the electricity-proof cover 2000 is provided so as to cover the periphery of the thermostat control device and the filter in order to prevent the user from being exposed to electric shock during use of the hot water apparatus. Referring to FIG. 1, the opening of the electricity-proof enclosure faces the housing, so that the thermostatic control device and the filter can be accommodated when the electricity-proof enclosure is fixed to the bottom of the housing. In addition, considering that the user needs to adjust the water temperature through the adjusting knob, a first relief opening (not labeled in the figure) is formed at the bottom of the electricity-proof cover for the adjusting knob 700 to leak out of the electricity-proof cover. Meanwhile, the bottom of the electricity-proof cover is also provided with a second yielding port (not marked in the figure) for the filter bottle 320 of the filter to extend out of the electricity-proof cover, so that a user can observe the internal condition of the filter device in time, and the filter device is convenient to clean or replace in time.

The utility model discloses technical scheme is through being provided with thermostatic control device and filter simultaneously in hot water system. Therefore, when the user uses the hot water device, the constant temperature control device can be used for controlling the temperature of the outlet water constantly, and the use comfort level is improved. Meanwhile, the installed filter optimizes and filters the water for the water heating device, gives clean water sources for users, and effectively improves the life quality of the users.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
