Description

Technical Field

[0001] This application belongs to the technical field of water heaters, and specifically relates to a water pipe fitting and a water heater. Background Art

[0002] An electric water heater is a device that heats cold water into hot water through electric energy. It is usually equipped with a thyristor to adjust the operating power of the whole machine to avoid the water output of the water heater being alternately hot and cold.

[0003] In the prior art, the thyristor generates a large amount of heat during operation. If it operates at a high temperature for a long time, it is likely to fail. Therefore, generally, an opening is provided on one side of the water pipe fitting where cold water flows in, a heat conducting member is provided on the opening, and a thyristor is provided on the heat conducting member, so that the thyristor exchanges heat with the cold water in the water pipe fitting through the heat conducting member, thereby realizing the heat dissipation of the thyristor.

[0004] However, the heat dissipation efficiency of the water pipe fitting arranged in this way for the thyristor is relatively low. Summary of the Invention

[0005] This application provides a water pipe fitting and a water heater to solve the problem that the heat dissipation efficiency of the existing water pipe fitting loaded with a thyristor for the thyristor is relatively low.

[0006] On the one hand, this application provides a water pipe fitting. The water pipe fitting is used to load a thyristor and is communicated with the water inlet of the water heater. It includes a loading pipe section, a flow baffle, and a heat conducting member. The loading pipe section is used for cold water to flow through. An installation part is provided on one side of the loading pipe section. An accommodation cavity communicated with the loading pipe section is provided in the installation part. An opening is provided on the installation part. The accommodation cavity is communicated with the outside through the opening. The flow baffle is arranged in the accommodation cavity. The heat conducting member seals the opening. The side of the heat conducting member away from the opening is used to connect with the thyristor;

[0007] The flow baffle is configured to block part of the cold water when the cold water flows through the accommodation cavity, so as to form a turbulent flow in the accommodation cavity.

[0008] In a possible implementation manner, for the water pipe fitting provided in this application, the flow baffle is a flow baffle plate, the flow baffle plate is arranged along the radial direction of the loading pipe section, and the flow baffle plate is located on the side of the cold water flowing direction in the accommodation cavity.

[0009] In a possible implementation manner, for the water pipe fitting provided in this application, the projection of the flow baffle along the axial direction of the loading pipe section occupies at least one-third of the cross section of the loading pipe section.

[0010] In a possible implementation manner, for the water pipe fitting provided in this application, the flow baffle and the heat conducting member are integrally formed.

[0011] In a possible implementation manner, for the water pipe fitting provided in this application, a plurality of convex portions are spacedly arranged on the surface of the flow baffle facing the inner side of the accommodation cavity.

[0012] In a possible implementation, for the water pipe fitting provided by the present application, at least one connecting portion is provided on the side surface of the flow blocking member. The connecting portion is adjacent to the end surface of the flow blocking member, and the connecting portion abuts against the inner wall of the mounting portion.

[0013] In a possible implementation, for the water pipe fitting provided by the present application, both the heat conducting member and the flow blocking member are metal members, and the extending direction of the heat conducting member is consistent with the extending direction of the loading pipe section.

[0014] In a possible implementation, for the water pipe fitting provided by the present application, connecting holes are provided on the circumferential side of the opening of the mounting portion, through holes are provided on the heat conducting member, and the through holes and the connecting holes are connected by threaded members.

[0015] In a possible implementation, for the water pipe fitting provided by the present application, a sealing groove is provided on the circumferential side of the opening of the mounting portion, a sealing member is provided in the sealing groove, and the heat conducting member is hermetically connected to the opening through the sealing member.

[0016] On the other hand, the present application provides a water heater, which includes a water heater body, a thyristor, and any one of the above water pipe fittings. The water pipe fitting is communicated with the water inlet of the water heater body, and the thyristor is arranged on the water pipe fitting.

[0017] For the water pipe fitting and the water heater provided by the present application, the water pipe fitting is communicated with the water inlet of the water heater. By providing a mounting portion with an accommodation cavity on one side of the loading pipe section of the water pipe fitting, the accommodation cavity is communicated with the inside of the loading pipe section and communicated with the outside through the opening on the mounting portion. Thus, a flow blocking member is inserted into the accommodation cavity through the opening, and a heat conducting member is arranged on the opening to cover the opening, and the thyristor is arranged on the heat conducting member. In this way, when cold water is injected into the water heater, the cold water will flow through the loading pipe section and the accommodation cavity, and then part of the cold water impacts on the flow blocking member. Under the blocking action of the flow blocking member, the original flow direction of this part of the cold water is forced to be disrupted, and then it interacts with the cold water flowing into the accommodation cavity subsequently to form a turbulent flow. Affected by the turbulent flow, the flowing time of the cold water in the accommodation cavity is prolonged, so as to facilitate the full heat exchange between the cold water and the heat conducting member to take away more heat. And part of the cold water will flow through the opening under the action of the turbulent flow and make full contact with the heat conducting member on the opening, further improving the heat exchange efficiency. Then, it flows into the water heater under the drive of the overall cold water flow trend, and finally prolongs the contact time between the cold water and the heat conducting member, realizing that the cold water takes away more heat of the heat conducting member under the action of the turbulent flow. Compared with the prior art in which the cold water exchanges heat briefly when flowing through the heat conducting member in the water pipe fitting, the present application can make part of the cold water stay in the accommodation cavity for a longer time, so as to contact and exchange heat with the heat conducting member more fully, thereby improving the heat dissipation efficiency of the thyristor, ensuring that the thyristor operates at a relatively low temperature, prolonging its service life, and having a simple and compact structure and occupying a small space.

These drawings and the written description are not intended to limit the scope of the concept of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by reference to specific embodiments. Detailed Description of the Embodiments

[0034] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below in conjunction with the accompanying drawings in the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without making creative efforts shall fall within the scope of protection of the present application.

[0035] In the specification and claims of the present application and the above-mentioned accompanying drawings, terms such as "first", "second", "third", "fourth", etc. (if any) are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0036] In the embodiments of the present application, words such as "exemplary" or "for example" are used to represent examples, illustrations, or explanations. Any embodiment or design solution described as "exemplary" or "for example" in the present application should not be construed as being more preferred or having more advantages than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "for example" is intended to present relevant concepts in a specific manner.

[0037] In the prior art, the power of a fast-heating water heater is relatively high and the current is relatively large during operation. During its operation, the thyristor, as a power regulation component of the fast-heating water heater, will also accumulate a large amount of heat. If the thyristor operates at a high temperature (especially above 125°C) for a long time and cannot dissipate heat effectively, it is very likely to cause failure.

[0038] Since the overall structure of the fast-heating water heater is relatively small and the internal layout is relatively compact, the structural dimensions of the water pipe components of its inlet and outlet pipes are limited, which in turn results in limited installation space for the thyristor. Generally, an opening is provided on one side of the water pipe component for flowing in cold water, a heat-conducting member is pasted on the opening, and the thyristor is provided on the heat-conducting member, so that the thyristor exchanges heat with the cold water in the inlet pipe through the heat-conducting sheet, thereby realizing the heat dissipation of the thyristor.

[0039] However, since it is not convenient to increase the effective contact area between the heat-conducting member and the cold water by expanding the opening in a limited space, the heat dissipation effect of the thyristor is limited, and it is difficult to further improve the heat dissipation efficiency.

[0040] To solve the above problems, the present application provides a water pipe fitting and a water heater. By installing a flow-blocking member inside the water pipe fitting, the flow-blocking member is used to extend the flow time of cold water at the heat-conducting member, enabling the cold water to fully contact and exchange heat with the heat-conducting member, thereby improving the heat dissipation efficiency of the thyristor. The overall structure is simple and compact, and the occupied space is also small.

[0041] The following will describe in detail the structure and principle of the water pipe fitting and the water heater provided by the present application with reference to the accompanying drawings.

[0042] Figure 1 It is a schematic structural diagram of the connection between the water pipe fitting provided by the embodiment of the present application and the thyristor; Figure 2 It is a schematic structural diagram of another perspective of the connection between the water pipe fitting provided by the embodiment of the present application and the thyristor; Figure 3 is Figure 2 a cross-sectional view taken along the A-A direction in Figure 4 is Figure 2 a cross-sectional view taken along the B-B direction in

[0043] On the one hand, the present application provides an embodiment of a water pipe fitting. Referring to Figures 1 to 4 as shown, the water pipe fitting is used to load the thyristor 400 and is communicated with the water inlet of the water heater. The water pipe fitting includes a loading pipe section 100, a flow-blocking member 200, and a heat-conducting member 300. The loading pipe section 100 is used for cold water to flow through. An installation part 110 is provided on one side of the loading pipe section 100. An accommodation cavity 111 communicating with the loading pipe section 100 is provided inside the installation part 110. An opening 112 is provided on the installation part 110. The accommodation cavity 111 communicates with the outside through the opening 112. The flow-blocking member 200 is arranged in the accommodation cavity 111. The heat-conducting member 300 seals the opening 112. The side of the heat-conducting member 300 facing away from the opening 112 is used to connect with the thyristor 400;

[0044] The flow-blocking member 200 is configured to block part of the cold water when the cold water flows through the accommodation cavity 111 to form a turbulent flow in the accommodation cavity 111.

[0045] It can be understood that the water pipe fitting being communicated with the water inlet of the water heater can be that the water pipe fitting is directly connected to the water inlet of the water heater, enabling the thyristor 400 to be arranged close to the inner tank of the water heater, thereby shortening the electrical connection distance between the thyristor 400 and other electrical components of the water heater. It can also be that the water pipe fitting is connected to the water inlet pipe of the water heater, connecting the water pipe fitting to the water inlet pipe and indirectly communicating with the water heater, making the disassembly, installation, and later maintenance of the water pipe fitting more flexible and convenient. The present application does not limit this.

[0046] The loading pipe section 100 only refers to the section of the water pipe fitting used to install the thyristor 400, and does not exclude the remaining pipe sections of the water pipe fitting. That is, the length, structure, and arrangement shape of the remaining pipe sections of the water pipe fitting are not restricted. Therefore, the water pipe fitting can be just a single-section water pipe structure with the loading pipe section 100 as shown in the figure. In some embodiments, the water pipe fitting can also be the water inlet pipeline of the water heater, and a selected section of the water pipe structure for loading the thyristor 400 is used as the loading pipe section 100, and the present application does not limit this either.

[0047] By providing an installation part 110 on one side of the loading pipe section 100, a receiving cavity 111 communicating with the inside of the loading pipe section 100 is formed within the installation part 110. The receiving cavity 111 is fitted with the water flow path inside the loading pipe section 100 so that an "intersection" is formed at the connection between the two, and no connecting pipe is provided, so that the cold water in the loading pipe section 100 can directly and unobstructedly fill the receiving cavity 111 and can circulate freely.

[0048] It should be noted that an opening 112 is provided on the installation part 110, and the size of the opening 112 can be the same as the inner diameter size of the receiving cavity 111, so that the size of the opening 112 is enlarged as much as possible to facilitate the disassembly and assembly operation of the flow blocking member 200 later. After the heat conducting member 300 covers the opening 112, the contact area between the heat conducting member 300 and the cold water is increased, thereby accelerating the heat exchange efficiency between the heat conducting member 300 and the thyristor 400 as much as possible.

[0049] Insert the flow blocking member 200 into the receiving cavity 111 and block a part of the flow cross-section of the loading pipe section 100, so that the flow blocking member 200 can block part of the cold water when the cold water flows through the loading pipe section 100 and the receiving cavity 111 without affecting the water inlet efficiency of the water heater. This is equivalent to forcibly disrupting the original flow direction of part of the cold water in the loading pipe section 100 by using the flow blocking member 200. This part of the cold water interacts with the cold water flowing into the receiving cavity 111 later to form a turbulent flow in the receiving cavity 111, making the flow lines in the receiving cavity 111 disordered and indistinguishable, and forming many small vortices in the flow field of the receiving cavity 111. The cold water in the receiving cavity 111 is affected by the turbulent flow, and the flow time in the receiving cavity 111 is extended, so as to facilitate the full heat exchange between the cold water and the heat conducting member 300 to take away more heat. And due to the action of the turbulent flow, the cold water flows disorderly in the receiving cavity 111 for a long time, and then inevitably comes into full contact with the heat conducting member 300 through the opening 112, so as to facilitate the heat conducting member 300 to exchange heat with the cold water at a higher efficiency and accelerate the heat dissipation of the thyristor 400.

[0050] Thus, when cold water is injected into the water heater through the water pipe provided by the present application, the cold water will flow through the loading pipe section 100 and the accommodating cavity 111, and then impact the baffle 200, and flow to the opening 112 under the blocking effect of the baffle 200, and fully contact the heat-conducting member 300 on the opening 112, thereby extending the contact time between the cold water and the heat-conducting member 300. Compared with the prior art in which the heat-conducting member 300 is simply attached to the opening 112 on the side of the water pipe, so that the cold water can exchange heat briefly when flowing through the heat-conducting member 300 in the water pipe, the present application can form a turbulent flow in the accommodating cavity 111 so that the cold water can stay in the accommodating cavity 111 for a longer time, thereby more fully contacting and exchanging heat with the heat-conducting member 300, so that the cold water can take away more heat, thereby improving the heat dissipation efficiency of the thyristor 400, ensuring that the thyristor 400 runs at a relatively low temperature, and extending its service life, and the overall structure is simple and compact, and the space occupied is also small.

[0051] Figure 5 A schematic diagram of a portion of the structure of a water pipe provided in an embodiment of the present application.

[0052] Reference Figure 5 As shown, in some embodiments, the baffle member 200 is a baffle plate, which is arranged along the radial direction of the loading pipe section 100 and is located on the side of the flow direction of the cold water in the accommodating cavity 111.

[0053] It can be understood that setting the baffle 200 as a sheet structure can make its structure compact and easy to install. When the baffle 200 needs to be installed, slots that are compatible with the two sides of the baffle 200 can be opened on the installation portion 110, and the baffle 200 can be directly inserted into the slots to achieve fixed installation without the need for fasteners, thereby further simplifying the overall structure.

[0054] Moreover, the sheet structure can also have a large surface area while ensuring that the overall structure is compact, so as to effectively block the water flow and form a stable and reliable spoiler effect.

[0055] The baffle is selected to be arranged along the radial direction of the loading pipe section 100, and to be arranged on the side of the cold water flow direction in the accommodating chamber 111. Specifically, it can be arranged on the upstream side or downstream side of the accommodating chamber 111 along the cold water flow direction, which is conducive to keeping the baffle perpendicular to the water flow direction and having a better flow blocking effect.

[0056] In other embodiments, the insertion angle and insertion position of the flow blocking member 200 may be adaptively adjusted according to specific usage conditions so as to form a flow blocking effect, and the present application does not impose any limitation on this.

[0057] Among them, Figure 4 and Figure 5 As shown, the projection of the baffle 200 along the axial direction of the loading pipe section 100 occupies at least one third of the cross section of the loading pipe section 100 .

[0058] It can be understood that when the baffle 200 is arranged radially along the loading pipe section 100, its baffle effect depends to a large extent on how much of the cross-section of the loading pipe section 100 is occupied by the projection of the baffle 200 along the axial direction of the loading pipe section 100, that is, the degree of occlusion of the loading pipe section 100 by the baffle 200. If the occlusion degree is small, it is beneficial to the rapid circulation of cold water, but the baffle effect is poor. If the occlusion degree is large, although the baffle effect is good, it is difficult to ensure the effective circulation of cold water, which hinders the normal water inlet of the water heater. That is, within a certain limit, as the occlusion degree gradually increases, the baffle effect of the baffle 200 is better, and the heat dissipation effect on the thyristor 400 is also better. Therefore, it is necessary to select an appropriate occlusion ratio. Exemplarily, the baffle 200 can occlude one-third of the cross-section of the loading pipe section 100 to balance the water inlet efficiency of the water heater and the baffle effect of the water pipe component, but should not exceed two-thirds of the cross-section of the loading pipe section 100.

[0059] In specific implementation, the projection of the baffle 200 along the axial direction of the loading pipe section 100 can be selected to occupy one-half of the cross-section of the loading pipe section 100 to obtain a relatively optimal baffle effect as much as possible without affecting the water inlet efficiency of the water inlet pipe of the water heater.

[0060] Taking this baffle 200 as an example, through fluid simulation analysis, when the ambient temperature is set to 25.9 °C and the heating temperature of the water heater is 50 °C, after operating stably for 15 minutes with an inlet water flow rate of 4.92 L / min and an operating power of 6840 W, compared with the case without the baffle 200, the inlet water temperature rises from 29.4 °C to 29.6 °C, an increase of 0.2 °C, the outlet water temperature rises from 49.2 °C to 49.3 °C, an increase of 0.1 °C, and the surface temperature of the thyristor 400 drops from 83.2 °C to 68.9 °C, with a small range of frequent fluctuations of about 2 °C during this period, that is, a reduction of nearly 15 °C. It can be seen that by using the water pipe component with the baffle 200 provided in the present application, it is possible to effectively reduce the surface temperature of the thyristor 400 while not affecting the normal operation of the water heater, improve the safety performance of the water heater, and optimize the user experience.

[0061] In addition, if the baffle plate occludes too much of the cross-section of the loading pipe section 100 so as to affect the normal water inlet of the water heater, flow-through holes can be appropriately processed on the baffle plate to neutralize the baffle effect of the baffle plate.

[0062] In some embodiments, referring to Figure 4 and Figure 5 as shown, the baffle 200 and the heat conducting member 300 are integrally formed.

[0063] It can be understood that since the baffle 200 is inserted into the accommodation cavity 111, it is equivalent to being immersed in cold water and directly contacting the cold water. The heat conducting member 300 covers the opening 112 communicating with the accommodation cavity 111 and also directly contacts the cold water through the opening 112. Therefore, the baffle 200 and the heat conducting member 300 can be integrally formed so that the two form a whole.

[0064] In this way, on the one hand, the baffle 200 and the heat conducting member 300 can be processed at one time, simplifying production and facilitating installation. On the other hand, the baffle 200 and the heat conducting member 300 can be connected to each other, and an additional heat transfer path is formed between the baffle 200 and the heat conducting member 300. The contact area between the heat conducting member 300 and the cold water is indirectly enlarged through the baffle 200, thereby accelerating the heat exchange efficiency of the heat conducting member 300 and further improving the heat dissipation effect of the thyristor 400.

[0065] Figure 6 For Figure 5 The partial enlargement of the baffle is shown at A in Figure 1 ; Figure 7 For Figure 5 The partial enlargement of the baffle is shown at A in Figure 2 .

[0066] Furthermore, as shown in reference to Figure 6 and Figure 7 , a plurality of protrusions are spaced on the surface of the baffle 200 facing the inner side of the accommodation cavity 111.

[0067] It should be noted that the protrusion can be a convex rib 210 extending radially along the loading pipe section 100 as shown in Figure 6 , or a convex circle 220 uniformly arranged as shown in Figure 7 . Whether it is the convex rib 210 or the convex circle 220, the protrusion is set to expand the surface area of the baffle 200 without changing the projected area of the baffle 200 along the extending direction of the loading pipe section 100, so that the cold water can contact the baffle 200 more fully and effectively, and the surface of the baffle 200 is uneven, making it easier to form a turbulent flow. In this way, when the baffle 200 and the heat conducting member 300 are connected to each other, the heat exchange of the heat conducting member 300 can be further accelerated.

[0068] Setting the protrusion on the surface of the baffle 200 facing the inner side of the accommodation cavity 111 is beneficial for the cold water to directly contact the protrusion when flowing through, ensuring the full and effective contact heat exchange.

[0069] Figure 8 For Figure 5 The partial enlargement of the baffle is shown at A in Figure 3 .

[0070] In addition, in some embodiments, with reference toFigure 4 and Figure 8 As shown in Figure 8 , at least one connecting portion 230 is provided on the side surface of the baffle 200. The connecting portion 230 is adjacent to the end surface of the baffle 200, and the connecting portion 230 abuts against the inner wall of the mounting portion 110.

[0071] It can be understood that by providing the connecting portion 230 on the side surface of the baffle 200 and making the connecting portion 230 adjacent to the end surface of the baffle 200, it is equivalent to extending one or both sides of the baffle 200, so that the baffle 200 is not only limited to forming a shield at the loading pipe section 100, but can also further extend into the accommodation cavity 111, as much as possible to expand the surface area of the baffle 200, and thereby accelerate the heat exchange between the heat conducting member 300 and the thyristor 400.

[0072] Wherein the connecting portion 230 always abuts against the inner wall of the mounting portion 110. It is easy to think that the connecting portion 230 extends along the inner wall of the mounting portion 110 and always fits with the mounting portion 110. At most, it can extend from the C-shaped baffle 200 shown in Figure 8 to both sides and close to form a baffle ring. Figure 8 to form a baffle ring as shown in Figure 8 .

[0073] This can facilitate the fixed connection between the baffle 200 and the mounting portion 110, and can also prevent the baffle 200 from excessively occupying the space of the accommodation cavity 111, ensuring that the internal structure of the water pipe member is relatively compact.

[0074] It should be noted here that for the structural setting of the baffle 200 shown in Figures 6 to 8 , it is not limited to the alternative setting, and can also be combined in pairs or all three are set at the same time. This application does not limit this. Figures 6 to 8 to the structural setting of the baffle 200 shown in Figures 6 to 8 , it is not limited to the alternative setting, and can also be combined in pairs or all three are set at the same time. This application does not limit this.

[0075] In some embodiments, as shown in Figures 1 to 3 , both the heat conducting member 300 and the baffle 200 are metal members, and the extending direction of the heat conducting member 300 is the same as the extending direction of the loading pipe section 100. Figures 1 to 3 As shown in Figures 1 to 3 , both the heat conducting member 300 and the baffle 200 are metal members, and the extending direction of the heat conducting member 300 is the same as the extending direction of the loading pipe section 100.

[0076] It is easy to understand that the metal member has a relatively high thermal conductivity, which is convenient for better helping the thyristor 400 to dissipate heat. Specifically, a copper baffle 200 and a heat conducting member 300 can be selected, and the cost is relatively low.

[0077] In other embodiments, since the baffle 200 is entirely immersed in water, the baffle 200 can also be made of plastic material to extend its service life.

[0078] By attaching the heat conducting member 300 along the extending direction of the loading pipe section 100, the overall structure of the water pipe member can be simple and compact, which is convenient for the cold water to fully contact the heat conducting member 300 through the opening 112, and is also convenient for installing the thyristor 400.

[0079] In addition, as shown in Figures 1 to 8 , Figures 1 to 8As shown, the installation part 110 is provided with connection holes 113 on the circumferential side of the opening 112, and the heat conducting member 300 is provided with through holes 310. The through holes 310 and the connection holes 113 are connected by threaded members.

[0080] By using threaded members for connection, connection holes 113 are provided on the installation part 110 around the opening 112, and through holes 310 corresponding to the connection holes 113 are provided on the heat conducting member 300, which can ensure the stable and reliable connection between the heat conducting member 300 and the installation part 110, and ensure the stability of the water pipe structure. Among them, the connection holes 113 are threaded holes, and the threaded members are bolts.

[0081] Furthermore, in some embodiments, as Figures 1 to 8 shown, the installation part 110 is provided with a sealing groove 120 on the circumferential side of the opening 112, and a sealing member 121 is arranged in the sealing groove 120. The heat conducting member 300 is hermetically connected to the opening 112 through the sealing member 121.

[0082] It can be understood that by providing a sealing groove 120 on the circumferential side of the opening 112 and installing the sealing member 121, when the heat conducting member 300 covers the opening 112, the sealing between the heat conducting member 300 and the opening 112 can be ensured through the sealing member 121, and the probability of water seepage between the opening and the heat conducting member can be reduced.

[0083] Among them, the sealing member 121 can be a sealing ring made of rubber material.

[0084] On the other hand, the present application also provides an embodiment of a water heater, including a water heater body, a thyristor 400, and the water pipe member in any of the above embodiments. The water pipe member is communicated with the water inlet of the water heater body, and the thyristor 400 is arranged on the water pipe member.

[0085] The structure and principle of the water pipe member have been described in detail in the above embodiments, and will not be elaborated here one by one.

[0086] In summary, for the water pipe member and the water heater provided by the present application, by setting the water inlet of the water heater to be communicated with the water pipe member, and arranging an installation part 110 with an accommodation cavity 111 on one side of the loading pipe section 100 of the water pipe member, the accommodation cavity 111 is communicated with the inside of the loading pipe section 100, and is communicated with the outside through the opening 112 on the installation part 110. Thus, a flow blocking member 200 is inserted into the accommodation cavity 111 through the opening 112, and a heat conducting member 300 is arranged on the opening 112 to cover the opening 112, and the thyristor 400 is arranged on the heat conducting member 300.

[0087] Thus, when cold water is injected into the water heater, the cold water will flow through the loading pipe section 100 and the accommodating cavity 111, and then impact on the flow blocking member 200. Under the blocking action of the flow blocking member 200, the original flow direction of part of the cold water is changed, so as to interact with the cold water flowing into the accommodating cavity 111 subsequently to form a turbulent flow in the accommodating cavity, prolong the time for the cold water to flow through the accommodating cavity 111, so that the cold water can take away more heat. And under the influence of the turbulent flow, part of the cold water is in full contact with the heat conducting member 300 on the opening 112, improving the heat exchange efficiency of the heat conducting member 300, and then flowing into the water heater under the drive of the overall cold water flow trend, finally realizing the prolonging of the contact time between the cold water and the heat conducting member 300.

[0088] Compared with the prior art in which the cold water exchanges heat briefly when flowing through the heat conducting member 300 in the water pipe member, the present application can enable part of the cold water to stay in the accommodating cavity 111 for a longer time, so as to contact and exchange heat with the heat conducting member 300 more fully, thereby improving the heat dissipation efficiency of the thyristor 400, ensuring that the thyristor 400 operates at a relatively low temperature, prolonging its service life, and having a simple and compact structure and occupying less space.

[0089] So far, the technical solutions of the present application have been described in combination with the preferred embodiments shown in the drawings. However, it is easy for those skilled in the art to understand that the protection scope of the present application is obviously not limited to these specific embodiments. The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
