Technical Field

[0001] The present invention belongs to the technical field of household appliances, and particularly relates to a decorative cover for a water heater and a water heater. Background Art

[0002] At present, with the improvement of people's living standards, there are more and more types of household appliances at home. Among them, there are also many types of water treatment equipment such as water heaters, water purifiers, and water softeners.

[0003] Water heaters are usually installed in the bathroom to facilitate the supply of hot water to the shower in the bathroom. In the actual use process, the bathroom is prone to generate peculiar smells due to various comprehensive reasons. Especially during the bathing process, due to the increase in temperature and humidity, the sense of peculiar smell will be more serious.

[0004] In view of this, how to design a water heater technology that can improve the air quality in the space to enhance the user experience is the technical problem to be solved by the present invention. Summary of the Invention

[0017] In some embodiments of the present application, an air suction port is further arranged on the side of the housing; and / or, the back of the housing is an open structure.

[0018] In some embodiments of the present application, one end of the air duct forms the air inlet, the other end of the air duct is a closed structure, the side wall of the air duct is provided with the air outlet, and the fan is connected to the air inlet.

[0019] In some embodiments of the present application, a through hole is arranged on the housing; an air outlet nozzle protruding outward is arranged on the side wall of the air duct, the air outlet is formed on the air outlet nozzle, and the air outlet nozzle is inserted into the through hole.

[0020] In some embodiments of the present application, the through hole is arranged at the bottom of the housing.

[0021] In some embodiments of the present application, the air outlet cross section of the air outlet nozzle gradually becomes smaller along the air outlet direction.

[0022] In an embodiment of the present invention, a water heater is further provided, which includes a housing and an inner tank disposed within the housing. An inlet pipe and an outlet pipe are provided on the inner tank, and the inlet pipe and the outlet pipe extend to the outside of the housing. The water heater also includes the above-mentioned decorative cover for the water heater; the cover body of the decorative cover for the water heater is disposed on the housing and is located in front of the inlet pipe and the outlet pipe.

[0023] In some embodiments of the present application, a leak-proof valve module is further included, and the leak-proof valve module includes:

[0024] A first water pipe, on which a first inlet pipe head, a first connecting pipe head and a first outlet pipe head are provided. A first connecting flow channel is also disposed within the first water pipe. One port of the first connecting flow channel communicates with the first inlet pipe head, and the second port of the first connecting flow channel communicates with the first connecting pipe head and the first outlet pipe head respectively;

[0025] A second water pipe, on which a second inlet pipe head, a second connecting pipe head and a second outlet pipe head are provided. A check valve is provided on the second inlet pipe head, and the check valve is configured to control the unidirectional flow of water from the second inlet pipe head into the second water pipe;

[0084] Example 1. As Figures 1 - 7 shown, an embodiment of the present application provides a decorative cover for a water heater, including

[0085] a cover body 1;

[0086] an aromatherapy module 2, the aromatherapy module 2 includes a blower 21, an air duct 22 and an aromatherapy component 23. The air duct 22 has an air inlet and an air outlet, and the blower 21 is arranged on the air duct 22;

[0087] The aromatherapy component includes a mounting seat 231, a container 232 and a heating device 233. The mounting seat 231 is provided with a mounting hole (not marked). The container 232 is used for containing aromatherapy material and is detachably arranged on the mounting seat 231. The heating device 233 is arranged on the mounting seat 231 and is used for heating the aromatherapy material to volatilize;

[0088] Wherein, a connection port (not marked) is also arranged on the air duct. The mounting seat 231 is arranged on the air duct. The mounting hole is communicated with the connection port. The aroma generated by heating and volatilizing the aromatherapy material by the heating device 233 enters the air duct through the connection port. The aromatherapy module 2 is arranged on the inner wall of the cover body 1.

[0089] Specifically, during the use of the decorative cover for the water heater, the cover body 1 is installed outside the outer shell of the water heater to achieve supporting use. During the user's bath, the blower 21 is started to make the air in the bathroom circulate and flow into the air duct 22. At the same time, the aromatherapy material is heated and volatilized by the heating device 233 being powered on and enters the air duct through the connection port, and is output to the bathroom along with the airflow flowing in the air duct, so as to aromatherapy the inside of the bathroom, ensure good air quality in the bathroom, and effectively improve the user experience.

[0090] By arranging an aromatherapy module in the housing, the blower configured in the aromatherapy module can suck the air in the bathroom into the air duct. At the same time, the aromatherapy component can heat and evaporate the aromatherapy material in the container and follow the air flow in the air duct to be output again from the air outlet of the air duct and flow back into the bathroom. In this way, the air in the bathroom can obtain the aromatherapy effect. The air in the bathroom is aromatherapy-treated through the aromatherapy module on the decorative cover to optimize the air quality in the space, thereby improving the user experience.

[0091] In some embodiments, an extension portion 221 extending outward is provided on the side of the air duct, and the connection port is provided on the extension portion 221.

[0092] Specifically, in order to facilitate the installation of the aromatherapy component 23, an extension portion 221 is arranged to extend outward on one side of the air duct. A channel is formed inside the extension portion 221 to communicate the connection port with the air duct. The aromatherapy component 23 is installed on the extension portion 221 to meet the installation requirements.

[0093] Due to the configuration of the extension portion 221, the air flow in the air duct can be smoothly transported.

[0094] In addition, the connection port can be arranged at the lower part of the extension portion 221, and the mounting seat 231 is arranged below the extension portion 221.

[0095] Specifically, the mounting seat 231 is assembled at the lower part of the extension portion 221 so that the aromatherapy component is on one side of the air duct to avoid the air outlet of the air duct, thereby ensuring smooth and efficient indoor air supply.

[0096] In some embodiments, the bottom of the container 232 extends below the lower edge of the housing 1.

[0097] Specifically, the container 232 is generally of a transparent or semi-transparent structure, and the aromatherapy material is contained therein. In order to facilitate the user to obtain the remaining amount of the aromatherapy material, the container 232 can be arranged to extend downward so that the bottom of the container 232 is exposed below the lower edge of the housing 1.

[0098] In some other embodiments, the aromatherapy material can be a liquid aromatherapy liquid. A liquid absorption rod 234 is provided at the upper part of the container 232, and the lower end of the liquid absorption rod 234 extends into the container 232; the heating device 233 is in a ring structure and surrounds the upper end of the liquid absorption rod 234.

[0099] Specifically, for the convenience of heating the aroma material, a liquid absorption rod 234 can be inserted into the container 232. The liquid absorption rod 234 can adsorb the aroma material in the container 232 and transport the aroma material to its upper end. The heating device 233 with an annular structure arranged at the upper end of the liquid absorption rod 234 can heat the liquid absorption rod 234, so that the aroma material adsorbed at the top of the liquid absorption rod 234 is heated and evaporated. At the same time, the aroma material in the container 232 will be gradually sucked to the top of the liquid absorption rod 234 to achieve continuous evaporation.

[0100] Similarly, the aroma material can also be a solid aroma block, and the heating device is in a plate-like structure and is arranged on the side or bottom of the container.

[0101] In some embodiments, one end of the air duct 22 forms the air inlet, the other end of the air duct 22 is a closed structure, the side wall of the air duct 22 is provided with the air outlet, and the fan 21 is connected to the air inlet.

[0102] Specifically, during the actual air supply process, the air flow after being sterilized by the air duct 22 is output through the air outlet arranged along the length direction of the air duct 22, so as to increase the air outlet coverage area and effectively disperse the sterilized air to the toilet.

[0103] In a certain embodiment, the cover 1 is provided with a through hole 11; the side wall of the air duct 22 is provided with an air outlet nozzle 24 protruding outward, the air outlet is formed on the air outlet nozzle 24, and the air outlet nozzle 24 is inserted into the through hole 11.

[0104] Specifically, by configuring an air outlet nozzle 24 protruding outward on the side wall of the air duct 22, the sterilized air is output outward through the air outlet nozzle 24. The air output by the air outlet nozzle 24 will form an air curtain, the air outlet is softer and the coverage range is larger. Moreover, since the air flow output by the air duct 22 is output through the air outlet nozzle 24, the air path short circuit of the air duct 22 can be effectively prevented, and the mutual influence between the inlet air and the outlet air can be avoided.

[0105] Among them, the bottom of the cover 1 is provided with a through hole 11. Specifically, the air output by the air outlet nozzle 24 is output outward from the bottom of the cover 1. The air outlet nozzle 24 can extend outward and pass through the through hole 11 to better transport the air downward. And the transported air will rise under the influence of the heat generated by the hot water at the bottom of the toilet, and then the air sterilization treatment of the entire toilet can be realized in a larger range to optimize the air quality of the entire toilet.

[0106] In addition, the air outlet cross-section of the air nozzle 24 gradually becomes smaller along the air outlet direction, which can improve the air outlet speed.

[0107] In other embodiments, in order to meet the air inlet requirements of the air duct 22, the side of the cover 1 is further provided with an air suction port 12; and / or, the back of the cover 1 is an open structure.

[0108] Specifically, the air duct 22 is arranged along the length direction of the cover body 1 as a whole, and the fan 21 is arranged at one end of the air duct 22 to connect to the air inlet. In this way, an air suction port 12 can be provided on the end face of the cover body 1 close to the fan 21 to meet the requirement that the air in the bathroom is sucked into the air duct 22 by the fan 21.

[0109] Similarly, for the cover body 1, its back is an open structure, and the fan 21 can directly suck air from the back of the cover body 1.

[0121] The second water inlet head 201 configured on the second water pipe 200 is used to connect to the water outlet pipe 6 of the water heater, so as to output the water processed by the water heater. The second water outlet head 203 of the second water pipe 200 is connected to a water using terminal in the user's home to achieve the final output of water.

[0122] The first water pipe 100 and the second water pipe 200 are connected through the connecting pipe 400, so that the first connecting head and the second connecting head are communicated with each other.

[0123] For the pressure on-off valve 300 in the first connecting head, it can perform corresponding actions according to the pressure generated between the water pressure in the first connecting head and the port two of the first connecting flow channel 104, so as to achieve the purpose of anti-leakage.

[0124] During the use process, generally, a conventional water heater is configured with two external connectors for connecting to external water pipes. During installation, the first water outlet head 103 is connected to one of the external connectors of the water heater, and the second water inlet head 201 is connected to the other external connector of the water heater.

[0125] When the user uses water through the water using terminal, at this time, the second water pipe 200 outputs water upward through the second water outlet and is connected to the water using terminal. At this time, the water pressure in the second water pipe 200 is lower than the water pressure at the first water inlet head 101. At the same time, since the first connecting head is communicated with the second connecting head through the connecting pipe 400, the water pressure at the first connecting head also correspondingly decreases. The water introduced from the first water inlet head 101 pushes open the pressure on-off valve 300 through the port two of the first connecting flow channel 104 and is finally discharged into the water heater through the first water outlet head 103.

[0126] After the user closes the water - using terminal, since the tap water pressure in the external water supply pipe is conducted to the second water pipe 200, the water pressure in the first connecting pipe head gradually increases and finally becomes the same as the water pressure in the first water inlet pipe head 101. At this time, the pressure on - off valve 300 will automatically reset to close port two of the first connecting flow channel 104.

[0127] At this time, if the water heater itself leaks due to internal rupture, since the one - way valve is configured at the second water inlet pipe head 201 of the second pipe body, when there is a leak at the water - using terminal, it will not cause a change in the water pressure in the second pipe body. Thus, the pressure on - off valve 300 always remains in the state of closing port two of the first connecting flow channel 104. Finally, in the case of damage inside the water heater, no tap water will be input into the water heater, thus preventing serious leakage.

[0128] By configuring a pressure on - off valve in the first water pipe, the pressure on - off valve is completely built into the first water pipe. The first water pipe is connected to the water supply pipe (tap water pipe) in the user's home through the first water inlet pipe head. The first water pipe and the second water pipe are respectively installed on the water heater in the user's home. When the water heater is in use, the water introduced into the first water pipe is output from the second water pipe after being processed by the water heater. At this time, since the connecting pipe connects the first connecting pipe head and the second connecting pipe head, the water pressure in the first connecting pipe head is lower than the water pressure in the first water inlet pipe head. At this time, the pressure on - off valve opens port two of the first connecting flow channel to connect the first water inlet pipe head and the first water outlet pipe head to achieve water supply. When the water heater is in the water - off state, the water pressures in the first water pipe and the second water pipe gradually become the same, making the water pressures in the first water inlet pipe head and the first connecting pipe head reach a balance. At this time, the pressure on - off valve automatically resets and closes port two of the first connecting flow channel; in the case of water leakage inside the water heater, since the one - way valve is set at the second water inlet pipe head, the water pressures in the first water inlet pipe head and the first connecting pipe head still maintain a balanced state, thereby ensuring that the water supply pipe does not output water outward from the first water pipe, reducing the occurrence of leakage accidents and improving the reliability of the electrical appliance.

[0129] In some embodiments, for the pressure on - off valve 300, it mainly relies on the water pressure difference between the first water inlet pipe head 101 and the first connecting pipe head to achieve mechanical on - off control. For this purpose, the pressure on - off valve 300 may include a spring 301 and a flexible sealing member 302. The flexible sealing member 302 is arranged in the first connecting pipe head 102 and is used to switch port two of the first connecting flow channel 104. The spring 301 is arranged in the first connecting pipe head 102 and is used to apply an elastic force to the flexible sealing member 302 in the direction towards port two of the first connecting flow channel 104.

[0130] Specifically, the flexible sealing member 302 is disposed opposite to the second port of the first connecting flow channel 104 and is used to block the second port of the first connecting flow channel 104. The two sides of the flexible sealing member 302 in the first connecting pipe head are respectively affected by the water pressures in different pipe heads, thereby deforming according to different pressure differences, and then opening and closing the second port of the first connecting flow channel 104.

[0131] During the process of the user using water through the water-using terminal, the water pressure in the first connecting pipe head decreases. Under the action of the water pressure at the second port of the first connecting flow channel 104, the flexible sealing member 302 will deform to open the second port of the first connecting flow channel 104. The water entering the first water pipe 100 from the first water inlet pipe head 101 is output from the second port of the first connecting flow channel 104 and finally flows into the water heater from the first water outlet pipe head 103.

[0132] When the user closes the water-using terminal to stop using water, the water pressure in the first connecting pipe head gradually rises to gradually cancel the water pressure generated at the second port of the first connecting flow channel 104. And, under the action of the spring 301, the flexible sealing member 302 deforms towards the second port of the first connecting flow channel 104 and finally blocks the second port of the first connecting flow channel 104.

[0133] In some embodiments, to facilitate the installation of the flexible sealing member 302, the flexible sealing member 302 is formed with a sealing portion 3021, an elastic deformation portion 3022, and a mounting and fixing portion 3023. The elastic deformation portion 3022 is connected between the sealing portion 3021 and the mounting and fixing portion 3023. The sealing portion 3021 is disposed opposite to the second port of the first connecting flow channel 104, and the mounting and fixing portion 3023 is disposed on the inner wall of the first connecting pipe head 102.

[0134] Specifically, the sealing portion 3021 formed by the flexible sealing member 302 is used to block the second port of the first connecting flow channel 104. The elastic deformation portion 3022 is used to meet the requirement that the sealing portion 3021 can open and close the second port of the first connecting flow channel 104 under different water pressures, and the mounting and fixing portion 3023 is used to be mounted in the first connecting pipe head.

[0135] In some embodiments, the pressure on-off valve 300 further includes a mounting and supporting member 303. The mounting and supporting member 303 is disposed in the first connecting pipe head. The spring 301 is disposed between the mounting and supporting member 303 and the sealing portion 3021. The spring 301 is used to apply an elastic force towards the second port of the first connecting flow channel 104 to the sealing portion 3021.

[0136] Specifically, to facilitate the installation of the spring 301 in the first connecting pipe head, an installation support member 303 can be provided in the first connecting pipe head by means of threaded connection or interference fit. The spring 301 is supported by the installation support member 303 so that the spring 301 can provide effective elastic force to the sealing portion 3021.

[0137] Among them, the installation support member 303 includes an outer sleeve 3031 and an inner sleeve 3032. The outer sleeve 3031 is sleeved outside the inner sleeve 3032, and a water flow channel 3033 is formed between the outer sleeve 3031 and the inner sleeve 3032. The outer sleeve 3031 is threadedly connected in the first connecting pipe head, and the spring 301 is arranged in the inner sleeve 3032.

[0138] Specifically, during assembly, the outer sleeve 3031 is installed in the first connecting pipe head by means of threaded connection. Since the outer sleeve 3031 and the inner sleeve 3032 are connected to each other, the spring 301 can be supported and installed through the inner sleeve 3032.

[0139] An inner sleeve 3032 can be suspended in the outer sleeve 3031 through a connecting rod between the outer sleeve 3031 and the inner sleeve 3032, thereby forming a water flow channel 3033.

[0140] The water flow channel 3033 can satisfy that the water pressure in the connecting pipe 400 is directly transmitted to the flexible sealing member 302 to ensure smooth water flow and accurate transmission of water pressure.

[0141] In some embodiments, to fixedly install the flexible sealing member 302, an installation ring 105 is provided in the first water pipe 100, and the installation fixing portion 3023 is clamped between the installation ring 105 and the outer sleeve 3031.

[0142] Specifically, the installation ring 105 is arranged on the inner wall of the first water pipe 100 on one side of the first connecting flow channel 104, and the installation ring 105 cooperates with the outer sleeve 3031 to fix the flexible sealing member 302.

[0143] During the assembly process, the flexible sealing member 302 is placed in the first connecting pipe head and abutted against the installation ring 105. Then, the outer sleeve 3031 is inserted into the first connecting pipe head. After the outer sleeve 3031 is installed in place, the installation fixing portion 3023 is clamped between the installation ring 105 and the outer sleeve 3031 to achieve firm fixed installation of the flexible sealing member 302.

[0144] In some embodiments, an adjusting member 304 is further provided in the inner sleeve 3032. The adjusting member 304 is threadedly connected in the inner sleeve 3032 and abuts against the spring 301.

[0145] Specifically, there are certain differences in the water pressure of the water supply pipe networks in different regions. Therefore, it is necessary to correspondingly adjust the elastic force generated by the spring 301 on the flexible sealing member 302 according to the local water pressure, so as to ensure that the flexible sealing member 302 can play a good sealing role for the first connecting flow channel 104.

[0146] During the actual use process, when the operator installs it in the user's home, before connecting the connecting pipe 400 to the first water pipe 100 and the second water pipe 200, the adjustment member 304 can be adjusted to change the deformation amount of the spring 301 in the initial state, so as to meet the water pressure requirements of the local water supply pipe network. For the adjustment member 304, preferably, threaded members such as bolts can be used.

[0147] After adjusting the initial deformation amount of the spring 301, the connecting pipe 400 can be connected between the first water pipe 100 and the second water pipe 200.

[0148] In another embodiment, in order to facilitate the user to directly perform the opening and closing operation of the water path of the anti-leakage device, a first auxiliary joint 106 is provided on the first water pipe 100. A first partition 107 is provided in the first auxiliary joint 106. A first water inlet (not marked) and a first water outlet (not marked) are provided on the first partition 107. The second port of the first connecting flow channel 104, the first water inlet, the first water outlet and the first water outlet pipe head 103 are connected in sequence;

[0149] A first switch valve 108 is provided in the first auxiliary joint 106. The first switch valve 108 is arranged opposite to the first partition 107 and is used to open and close the first water inlet and / or the first water outlet.

[0150] Specifically, during the actual use process, when the user needs to completely close the anti-leakage device, the first switch valve 108 can be operated to act, and the first water inlet and / or the first water outlet are opened and closed through the first switch valve 108 to actively control the on-off of the flow path between the first water inlet pipe head 101 and the first water outlet pipe head 103. Furthermore, when the anti-leakage device needs to be completely closed, it is more conducive to further improving the use reliability.

[0151] The specific structure of the first switch valve 108 can adopt the valve core structure in a conventional water valve, which will not be limited and elaborated here.

[0152] In another embodiment, a second connecting flow channel 204 is further provided in the second water pipe 200. The first port of the second connecting flow channel 204 is communicated with the second water inlet pipe head 201, and the second port of the second connecting flow channel 204 is respectively communicated with the second connecting pipe head 202 and the second water outlet pipe head 203.

[0153] Specifically, for the second water inlet head 201, in order to meet the requirement of supplying water to the second water outlet head 203 and the second connecting pipe head together, a second connecting flow channel 204 is configured in the second water pipe 200 to achieve the distribution of water flow.

[0154] Similarly, in order to completely close the second water pipe 200, a second auxiliary joint 205 is provided on the second water pipe 200. A second partition plate 206 is provided in the second auxiliary joint 205. A second water inlet and a second water outlet are provided on the first partition plate 107. Port two of the second connecting flow channel 204 is the second water inlet, and the second water outlet is communicated with the second water outlet head 203 and the second connecting pipe head respectively; a second switch valve 207 is provided in the second auxiliary joint 205. The second switch valve 207 is arranged opposite to the second partition plate 206 and is used to switch the second water inlet and / or the second water outlet.

[0155] Specifically, in the actual use process, when the user needs to completely close the second water pipe 200, the second switch valve 207 can be operated to act, and the second water inlet and / or the second water outlet are switched by the second switch valve 207 to actively control the on-off of the flow path between the second water inlet head 201 and the second water outlet head 203 and the second connecting pipe head, and then the second water pipe can be completely closed as needed, which is more conducive to further improving the use reliability.

[0156] The specific structure of the second switch valve 207 can adopt the valve core structure in a conventional water valve, which is not limited and described in detail here.
