Fig. 1 is a schematic cross-sectional view of an outlet pipe 100 according to an embodiment of the present invention. Fig. 2 is a schematic cross-sectional view of an outlet pipe 100 according to another embodiment of the present invention. Fig. 3 is a schematic cross-sectional view of an outlet pipe 100 according to yet another embodiment of the present invention.

An embodiment of the present invention provides a water outlet pipe 100, including: a tube body 140 and an electrical switching apparatus 200. The tube body 140 has an inlet 120 and an outlet 130. The tube body 140 defines therein a gas-liquid mixing chamber 110, and a sectional area of the gas-liquid mixing chamber 110 is larger than that of the through hole 201. The electric switch device 200 is disposed at a portion of the pipe body 140 where the gas-liquid mixing chamber 110 is not formed, and the electric switch device 200 is configured to controllably adjust an opening degree of the water path of the water outlet pipe 100, so that the water path is opened at different opening degrees by controlling the operation of the electric switch device 200 to control the water outlet pipe 100 to supply gas-dissolved water or supply normal water. Fig. 4 is a schematic diagram of a water heater 300 having the outlet pipe 100 shown in fig. 1. Fig. 7 is a schematic diagram of a water heater 300 having the outlet pipe 100 shown in fig. 3. The embodiment of the present invention further provides a water heater 300, which may include an inner container 301, a heating element 304, an inlet pipe 302 and the aforementioned outlet pipe 100. The inner container 301 is used for containing water. The water inlet pipe 302 is used for introducing water into the inner container 301. The heating member 304 is used to heat the water in the inner container 301. The water outlet pipe 100 is used for leading water in the inner container 301 out of the inner container 301. The outlet 130 of the water outlet pipe 100 is connected to a shower head 400 having an air release device (not shown) for releasing air from the dissolved air water to form micro bubble water. The outlet pipe 100 and the water heater 300 of the embodiment of the invention are characterized in that the outlet pipe 100 comprises a pipe body 140 and an electric switch device 200, the pipe body 140 is provided with a gas-liquid mixing cavity 110, the sectional area of the gas-liquid mixing cavity 110 is larger than that of the inlet 120, the electric switch device 200 is arranged at the part of the pipe body 140 where the gas-liquid mixing cavity 110 is not formed, and the electric switch device 200 is configured to controllably adjust the opening degree of the water path of the outlet pipe 100, so that the outlet type of the outlet pipe 100 and the water heater 300 can be controlled by controlling the action of the electric switch device 200 to open different opening degrees of the water path. Specifically, when the inlets 120 are the same (i.e., the water has the same flow restriction effect at the inlets 120), the greater the flow rate of water through the outlet pipe 100, the greater the flow rate of water entering the inlets 120, and the more thoroughly the water mixes with the gas in the outlet pipe 100. Therefore, the mixing degree of the water and the gas can be adjusted by adjusting the flow rate of the water, namely, the water outlet type of the water outlet pipe 100 can be changed by adjusting the opening degree of the water path. The switching water outlet structure of the water outlet pipe 100 of the embodiment of the invention is ingenious and is easy to configure and control. The water outlet type of the water heater 300 with the water outlet pipe 100 of the embodiment of the invention is adjustable, and the use experience of a user is improved.

The water heater 300 of the embodiment of the invention directly forms the dissolved air water in the water outlet pipe 100, so that no additional part is needed, the whole volume of the water heater 300 is hardly influenced, a water path joint cannot be increased, and the water leakage risk cannot be increased. As shown in fig. 1 and 2, a partial section of the outlet pipe 100 defines a gas-liquid mixing chamber 110; and as shown in fig. 3, almost all sections of the outlet pipe 100 define the gas-liquid mixing chamber 110. When the water outlet pipe 100 of the embodiment of the invention is applied to the water heater 300, the gas-liquid mixing cavity 110 may be located outside the inner container 301, as shown in fig. 4; or the gas-liquid mixing cavity 110 can be positioned inside the liner 301, as shown in fig. 7; alternatively, the gas-liquid mixing chamber 110 may be partially inside the inner container 301 and partially outside the inner container 301, as shown in fig. 8. When the same water outlet pipe 100 has a plurality of gas-liquid mixing chambers 110, part of the gas-liquid mixing chambers 110 may be located inside the inner container 301, and part of the gas-liquid mixing chambers 110 may be located outside the inner container 301.

The sectional area of the gas-liquid mixing chamber 110 is larger than that of the inlet 120, and the sectional area of each position of the gas-liquid mixing chamber 110 may be larger than that of the inlet 120, or the sectional area of a part of the gas-liquid mixing chamber 110 may be larger than that of the inlet 120, and the sectional areas of other parts may not be smaller than that of the inlet 120. For example, in fig. 1, the cross-sectional area of the inlet 120 may be smaller than the maximum cross-sectional area of the gas-liquid mixing chamber 110. Preferably, in order to increase the volume of the gas-liquid mixing chamber 110 so as to accommodate more gas to generate gas-dissolved water, the gas-liquid mixing effect is improved, and the sectional area of each position of the gas-liquid mixing chamber 110 is larger than that of the inlet 120.

In some embodiments, outlet pipe 100 of embodiments of the present invention is configured to: the electric switch device 200 is controlled to operate to fully open the water channel to supply dissolved air water, and the electric switch device 200 is controlled to operate to incompletely open the water channel to supply ordinary water. The electric switch device 200 is configured to realize the supply of the dissolved air water when the electric switch device 200 is controlled to operate to completely open the water path and realize the supply of the common water when the electric switch device 200 is controlled to operate to incompletely open the water path, so that the control logic of the electric switch device 200 is simple, the response is quick, that is, the logic of the water outlet type switching of the water outlet pipe 100 is simple and easy to realize. When the electric switch device 200 is controlled to act to completely open the water channel, the water in the inner container 301 can be ensured to flow into the water outlet pipe 100 from the inlet 120 at the top of the water outlet pipe 100 at a larger flow speed, a certain amount of gas is stored in the water outlet pipe 100, the contact area of the water limited by the inlet 120 and the gas is increased to form gas-dissolved water, the gas-dissolved water flows out from the water outlet pipe 100 at the moment, and the gas-dissolved water is discharged from the outlet 130 of the water outlet pipe 100 and then passes through the gas release device to generate micro-bubble water, namely, the micro-bubble water flows out from the shower head 400. When the electric switch device 200 is controlled to operate to open the water path incompletely, at this time, the electric switch device 200 limits the flow of the water path, and the flow of the water passing through the water outlet pipe 100 is reduced, so that the water in the inner container 301 flows into the water outlet pipe 100 from the inlet 120 at the top of the water outlet pipe 100 at a relatively low flow rate, and is insufficiently mixed with the gas in the water outlet pipe 100, so that gas-dissolved water cannot be formed or the gas-dissolved water cannot reach a specific concentration, and only ordinary water can be generated, i.e., the ordinary water flows out from the water outlet pipe 100 and corresponds to the ordinary water flowing out from the shower head 400.

The inlet 120 of the outlet pipe 100 according to the embodiment of the present invention may be used to fill water into the outlet pipe 100 or fill water and gas into the outlet pipe 100. When the inlet 120 is only used for filling water into the water outlet pipe 100, the water outlet pipe 100 may be provided with an air inlet capable of being opened and closed. When the water outlet pipe 100 is applied to the water heater 300, the air dissolving effect can be improved by pressurizing the water flow path, which can be realized by adding the water pump 305 or the air pump or making the water have a certain pressure. For example, in fig. 7, a water pump 305 is added to the water inlet pipe 302, and the water pump 305 may be configured to be turned on when the waterway is fully opened.

In some embodiments, pipe body 140 of outlet pipe 100 according to embodiments of the present invention has first pipe segment 501, second pipe segment 502, and third pipe segment 503 connected in sequence, where a top end of first pipe segment 501 forms inlet 120, a bottom end of third pipe segment 503 forms outlet 130, and a cross-sectional area of second pipe segment 502 is larger than cross-sectional areas of first pipe segment 501 and third pipe segment 503 to define gas-liquid mixing chamber 110 at second pipe segment 502; wherein the electrical switching apparatus 200 is disposed in the first pipe segment 501 or in the third pipe segment 503. As shown in fig. 1 and 2, first tube segment 501 has a substantially straight cylindrical shape, second tube segment 502 has a substantially hollow spherical configuration, and third tube segment 503 has a substantially straight cylindrical shape, with outlet 130 disposed opposite inlet 120. In the outlet pipe 100 shown in fig. 1, the electrical switching apparatus 200 is provided on the first pipe section 501; in the outlet pipe 100 shown in fig. 2, the electrical switching apparatus 200 is provided on the third pipe section 503. The second tube segment 502 may have a variety of shapes, such as spherical, ellipsoidal, cylindrical, contoured, and the like.

In other embodiments, the tube body 140 of the outlet tube 100 according to the embodiment of the present invention has a side wall 601, a top wall 602 and a bottom wall 603, the top end of the side wall 601 is provided with the top wall 602, the bottom end of the side wall 601 is provided with the bottom wall 603, wherein the top wall 602 is provided with the inlet 120, the bottom wall 603 is provided with the outlet 130, and the inner surface of the side wall 601, the lower surface of the top wall 602 and the upper surface of the bottom wall 603 jointly define the gas-liquid mixing chamber 110; wherein the electrical switching apparatus 200 is disposed at the bottom wall portion 603. As shown in fig. 3, the tube body 140 has a straight cylindrical shape as a whole, and the inner hole radius r of the side wall portion 601 is constant from top to bottom.

Fig. 9 is a schematic diagram of the components of the water heater 300 shown in fig. 4. Fig. 10 is a flow chart illustrating a control method of the water heater 300 shown in fig. 4. Fig. 11 is a flow chart illustrating a control method of the water heater 300 shown in fig. 4. The control method of the water heater 300 according to the embodiment of the present invention will be briefly described with reference to fig. 9 to 11.

In some embodiments, the water heater 300 of embodiments of the present invention further includes: a voice recognition device 701 and a control device 800. The voice recognition device 701 is used for receiving and recognizing voice information sent by a user. The control device 800 is configured to generate control commands based on the voice information to control the action of the electric switch device 200 to adjust the opening degree of the water path of the water outlet pipe 100, wherein the control commands include a general water supply command and a micro-bubble water supply command.

The voice message uttered by the user may be, for example, "plain water", "plain water supply", "micro-bubble water supply", "micro-bubble water bath", and the like. The control device 800 may store the correspondence between the voice information and the control command in advance. And a plurality of voice messages can correspond to the same control instruction. For example, the aforementioned "general water", "supply general water", and "supply general water" correspond to the "supply general water command". For example, the aforementioned "micro-bubble water", "supply micro-bubble water", "micro-bubble water bath" correspond to the "micro-bubble water supply command". The speech recognition device 701 may be mounted on the front wall or outside the side walls of the inner container 301. Thus, when the user speaks "supply normal water" to the water heater 300, the voice recognition device 701 receives and recognizes that the voice message uttered by the user is "supply normal water", and in response to the control command being "supply normal water", the control device 800 controls the operation of the electric switch device 200 such that the water path is not completely opened, thereby realizing the supply of normal water. When a user speaks "provide micro-bubble water" towards the water heater 300, the voice recognition device 701 receives and recognizes that the voice message sent by the user is "provide micro-bubble water", and the corresponding control command is "supply micro-bubble water command", and the control device 800 controls the electric switch device 200 to operate to completely open the water path, so as to supply micro-bubble water.

Taking the water heater 300 shown in fig. 4 as an example, the control method of the water heater 300 is shown in fig. 10, and includes the following steps:

s102: receiving and identifying voice information sent by a user;

s104: generating a control instruction based on the voice information;

s106: when the control command is a command for supplying common water, the electric switch device 200 is controlled to operate to ensure that the water way is not completely opened, the water outlet pipe 100 discharges the common water, and the shower head 400 discharges the common water;

s108: when the control instruction is a micro-bubble water supply instruction, the electric switch device 200 is controlled to act to completely open the water path, the water outlet pipe 100 discharges dissolved air water, and the shower head 400 discharges micro-bubble water.

In some embodiments, the water heater 300 of embodiments of the present invention further includes: and the action recognition device 702 is used for collecting and recognizing the action information of the user. The control device 800 is configured to generate a control command based on the operation information to control the electric switch device 200 to operate to adjust the opening degree of the water path of the water outlet pipe 100; wherein the control instructions include a supply plain water instruction and a supply micro bubble water instruction.

The motion recognition means 702 may be, for example, a radar sensor. The user's motion information may be, for example, forward and reverse direction circling, left and right hand circling, and so on. The control device 800 may store the correspondence between the operation information and the control command in advance. And a plurality of pieces of action information may correspond to the same control instruction. For example, the 'clockwise circling' and 'right hand circling' are set to correspond to the 'general water supply instruction', the 'anticlockwise circling' and 'left hand circling' are set to correspond to the 'micro bubble water supply instruction'. The motion recognition device 702 may be mounted on the outside of the front wall or side wall of the inner container 301. Therefore, when the user circles clockwise with respect to the water heater 300, the motion recognition device 702 receives and recognizes that the motion information sent by the user is "circling clockwise", and corresponds to the control command "supply normal water command", and the control device 800 controls the electric switch device 200 to operate so that the water path is not completely opened, thereby supplying normal water. When the user circles counterclockwise facing the water heater 300, the motion recognition device 702 receives and recognizes that the motion information sent by the user is "circle counterclockwise", and the corresponding control instruction is "supply micro-bubble water instruction", and the control device 800 controls the electric switch device 200 to operate to completely open the water path, so as to supply micro-bubble water.

Taking the water heater 300 shown in fig. 4 as an example, the control method of the water heater 300 is shown in fig. 11, and includes the following steps:

s202: receiving and identifying action information sent by a user;

s204: generating a control instruction based on the action information;

s206: when the control instruction is an instruction for supplying common water, the electric switch device 200 is controlled to operate to ensure that the water way is not opened completely, the water outlet pipe 100 discharges the common water, and the shower head 400 discharges the common water;

s208: when the control instruction is a micro-bubble water supply instruction, the electric switch device 200 is controlled to act to completely open the water path, the water outlet pipe 100 discharges dissolved air water, and the shower head 400 discharges micro-bubble water.

The control device 800 of the water heater 300 according to the embodiment of the present invention may include a processor 801 and a memory 802, wherein the memory 802 stores a machine executable program 820, and the machine executable program 820 is used for implementing the aforementioned control method of the water heater 300 when being executed by the processor 801.

Fig. 5 is a partial structural view of the insulator 900 and the outlet pipe 100 of the water heater 300 shown in fig. 4. Fig. 6 is another partial structure diagram of the insulating member 900 and the outlet pipe 100. In some embodiments, in the water heater 300 according to the embodiment of the present invention, the pipe body 140 is provided with the insulating member 900 at a junction with the inner container 301, the first metal thread structure 901 is embedded in an upper portion of the insulating member 900, and the water outlet pipe 100 is fixed to the inner container 301 by using the first metal thread structure 901. For the outlet pipe 100 shown in fig. 1 having the first pipe segment 501, the second pipe segment 502 and the third pipe segment 503, when the second pipe segment 502 is disposed outside the inner container 301, the insulating member 900 may be disposed at the joint of the first pipe segment 501 and the second pipe segment 502. For the water outlet pipe 100 shown in fig. 3, when the gas-liquid mixing chamber 110 is entirely disposed inside the inner container 301, the insulating member 900 may be disposed at the bottom wall portion 603; when the gas-liquid mixing chamber 110 is disposed across the inside and outside of the inner container 301, the insulator 900 may be disposed on the side wall portion 601.

The water heater 300 of the embodiment of the invention can realize safe water utilization by adopting the modes of water outlet, power failure and the like. The water outlet pipe 100 of the embodiment of the present invention may also be configured to have an electricity-proof wall function, so that the water outlet pipe 100 of the embodiment of the present invention may generate normal water or dissolved air water under the conditions of ensuring normal water outlet and electricity-proof.

In some embodiments, the tube body 140 of the water outlet tube 100 of the embodiment of the present invention is made of an insulating material. The pipe body 140 is, for example, a plastic pipe. In other embodiments, the tube body 140 of the outlet tube 100 of embodiments of the present invention has an insulating inner layer 101 and a metal outer layer 102, the metal outer layer 102 wrapping at least a portion of the insulating inner layer 101. The metal outer layer 102 serves to protect the insulating inner layer 101. In still other embodiments, a partial section of the tube body 140 of the water outlet tube 100 of the embodiment of the present invention is made of an insulating material, and a partial section is made of a metal material.

According to specific test and reference GB13955-92 (leakage protector mounting and operating) gaugeThe leakage current of the electric water heater 300 is set to 10mA, so that the safety of a user can be ensured. When electric leakage occurs in the heating inner container 301 or the used 220V power supply is directly short-circuited with the heated water, the medium resistance of the tap water is R =220V/10mA =22 × 10 ³ Omega. The water resistance of the water outlet pipe 100 is the sum of the water resistance of the gas-liquid mixing chamber 110 and the water resistance of the part where the gas-liquid mixing chamber 110 is not formed. Therefore, the water outlet pipe 100 of the embodiment of the present invention is further configured to: adjusting one or more of the material of the tube body 140 of the water outlet tube 100, the inner bore radius, the length and the water channel structure of the portion of the tube body 140 not forming the gas-liquid mixing cavity 110 to make the water resistance of the water outlet tube 100 reach 22 × 10 ³ Omega. For example, the insulating portion of the water outlet pipe 100 may be increased, or the inner hole radius of the portion of the water outlet pipe 100 where the gas-liquid mixing cavity 110 is not formed may be decreased, or a water channel structure may be added to the portion of the water outlet pipe 100 where the gas-liquid mixing cavity 110 is not formed, for example, the water channel is configured as an insulating wall similar to a mosquito coil, and water may flow to the center from the outside in a rotating manner and then flow out of the water outlet pipe 100, so as to achieve the purpose of extending the water channel.

Taking the water outlet pipe 100 shown in fig. 1 and fig. 3 as an example and combining fig. 4 to fig. 8, a brief description will be given of the structure of the water outlet pipe 100 implementing the electricity-proof wall function according to the embodiment of the present invention.

For the water outlet pipe 100 shown in fig. 1, when the first pipe segment 501 is located inside the inner container 301, and the second pipe segment 502 and the third pipe segment 503 are located outside the inner container 301, as shown in fig. 4, since the inner hole radius of the first pipe segment 501 located inside the inner container 301 is constant and small (which may be approximately the inner hole radius of the existing water outlet pipe of a common water heater), it is possible to set the first pipe segment 501 as an insulating material to meet the requirement that the water resistance of the water outlet pipe 100 reaches 22 × 10 ³ Omega. At this time, when the second pipe section 502, the third pipe section 503 and the first pipe section 501 are of an integral structure, that is, the second pipe section 502 and the third pipe section 503 are also made of insulating materials, the matching structure of the insulating member 900 and the water outlet pipe 100 can be as shown in fig. 5. Namely, the upper part of the insulating member 900 is embedded with a first metal thread structure 901, and the water outlet pipe 100 is fixed to the inner container 301 by using the first metal thread structure 901. A sealing ring 903 may also be provided between the metal outer layer 102 and the insulator 900. Further, it may be in the first pipeThe outer metal layer 102 is arranged outside the inner insulating layer 101 of the segment 501 in the inner container 301 to protect the inner insulating layer 101. When the second tube section 502, the third tube section 503 and the first tube section 501 are of a split structure, for example, the second tube section 502 and the third tube section 503 are made of metal, the matching structure of the insulating member 900 and the water outlet pipe 100 can be as shown in fig. 6. The second and

third pipe sections

502, 503 are not shown in fig. 6. In contrast to fig. 5, the insulating member 900 of fig. 6 has a first metal screw structure 901 embedded in an upper portion thereof and a second metal screw structure 902 embedded in a lower portion thereof. Thereby allowing the split outlet pipe 100 to be fitted. Taking the water outlet pipe 100 shown in fig. 1 as an example, the lower end of the first pipe segment 501 is matched with the first metal thread structure 901 of the insulating member 900 and the inner container 301, and the upper end of the second pipe segment 502 is matched with the second metal thread structure 902 of the insulating member 900. With continued reference to fig. 6, a portion 904 of the insulator 900 between the first and second

metal thread structures

901, 902 forms a portion of the water path of the outlet pipe 100. Therefore, the water resistance of the outlet pipe 100 can also be satisfied by reducing the inner bore radius of the partial section 904 of the insulating member 900, increasing the length L, or adding a waterway structure to the partial section 904.

For the water outlet pipe 100 shown in fig. 1, when the second pipe section 502 is wholly or partially located inside the inner container 301, the water resistance of the water outlet pipe 100 can be satisfied by reducing the inner hole radius of the first pipe section 501 and the third pipe section 503 or adding a water path structure at the first pipe section 501 and the third pipe section 503. Also, when the partial section 904 of the insulator 900 forms a part of the water course of the outlet pipe 100, similarly to the above, the water resistance of the outlet pipe 100 may be satisfied by reducing the inner bore radius of the partial section 904 of the insulator 900, increasing the length L, or adding a waterway structure or the like to the partial section 904.

For the water outlet pipe 100 shown in fig. 3, when the gas-liquid mixing chamber 110 is completely located inside the inner container 301, that is, the sidewall 601 is completely located inside the inner container 301, and the insulating member 900 is fixed to the bottom wall 603, as shown in fig. 7, since the inner hole radius r of the sidewall 601 located inside the inner container 301 is constant but larger (obviously larger than the inner hole radius of the water outlet pipe of the conventional ordinary water heater),the insulating material of the sidewall 601 may not satisfy the water resistance of the outlet pipe 100 of 22 × 10 ³ Omega. At this time, the water resistance of the water outlet pipe 100 can be satisfied by reducing the inner hole radius of the bottom wall portion 603, or increasing the length of the bottom wall portion 603, or adding a waterway structure at the bottom wall portion 603. It is understood that when the length of the bottom wall portion 603 is increased to a certain extent, the water outlet pipe 100 is not the gas-liquid mixing chamber 110 in all sections, but the water outlet pipe 100 of the gas-liquid mixing chamber 110 in some sections as shown in fig. 1, and the gas-liquid mixing chamber 110 is only located at the upper portion of the water outlet pipe 100, not at the lower portion. Also, when the partial section 904 of the insulator 900 forms a part of the water path of the outlet pipe 100, similarly to the above, the water resistance of the outlet pipe 100 can be satisfied by reducing the inner bore radius of the partial section 904 of the insulator 900, increasing the length L, or adding a water path structure to the partial section 904, etc.

For the water outlet pipe 100 shown in fig. 3, when the gas-liquid mixing chamber 110 is partially located inside the inner container 301, that is, the sidewall 601 is partially located inside the inner container 301, the insulating member 900 is fixed to the sidewall 601, as shown in fig. 8, since the inner hole radius of the sidewall 601 located inside the inner container 301 is constant but large, the insulating material of the sidewall 601 may not satisfy the requirement that the water resistance of the water outlet pipe 100 reaches 22 × 10 by merely providing the sidewall 601 as an insulating material ³ Omega. At this time, the water resistance of the outlet pipe 100 can be satisfied by reducing the inner hole radius of the bottom wall portion 603, or increasing the length of the bottom wall portion 603, or adding a waterway structure at the bottom wall portion 603. In this embodiment, since the insulating member 900 is fixed to the side wall 601, in order to ensure that the inner diameter of the gas-liquid mixing chamber 110 remains large, the insulating member 900 is combined with the water outlet pipe 100 in a manner similar to fig. 5, i.e., only serves as a mounting member for fixing the water outlet pipe 100 to the inner container 301 without participating in the water path of the water outlet pipe 100.
