The housing has an installation cavity, and a limiting groove is formed on the inner wall of the installation cavity; the electronic control module and the condenser are disposed on opposite sides of the housing; one end of the temperature sensor is electrically connected to the electronic control module, and the other end passes through the limiting groove and extends out of the housing, so that a part of the temperature sensor is limited in the limiting groove.

[0007] As an optional implementation manner, the limiting groove extends obliquely, and the limiting groove has a first end and a second end; wherein, the first end is close to the electronic control module, the second end is close to the condenser, and the second end is located below the first end.

[0009] As an alternative embodiment, the housing includes a top plate, a bottom plate, two first enclosing plates and two second enclosing plates. The top plate and the bottom plate are arranged at intervals in the height direction of the water heater. The two first enclosing plates are oppositely arranged in a first direction, and the two second enclosing plates are oppositely arranged in a second direction. The two first enclosing plates and the two second enclosing plates are connected between the top plate and the bottom plate. The top plate, the bottom plate, the two first enclosing plates and the two second enclosing plates enclose an installation cavity. Wherein, the first direction is perpendicular to the second direction. The electronic control module and the condenser are respectively located outside the two first enclosing plates, and the condenser is located between the top plate and the bottom plate. The limiting groove is formed on the inner plate surface of any one of the second enclosing plates.

[0010] As an alternative embodiment, the water heater is for fixing to an installation surface. The two second enclosing plates include a rear enclosing plate for facing the installation surface, and the limiting groove is formed on the inner plate surface of the rear enclosing plate.

[0011] As an alternative embodiment, the rear enclosing plate has a stop surface facing the condenser, and the second end is formed on the stop surface.

[0012] As an alternative embodiment, the other end of the temperature sensor extends away from the condenser under the extrusion of the housing and the condenser.

[0032] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of this application.

[0033] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If this specific posture changes, then the directional indications will also change accordingly.

[0034] In addition, descriptions such as "first" and "second" in this application are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of this application, "a plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0035] In this application, unless otherwise clearly specified and limited, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal connection of two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0036] In addition, the technical solutions between the various embodiments of the present application can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present application.

[0037] In the related art, a water heater includes a housing, an electronic control module, a temperature sensor, and a condenser. The electronic control module is disposed on the side of the housing. One end of the temperature sensor is connected to the electronic control module, and the other end extends out of the housing and is disposed close to the condenser. The condenser is installed in the housing. Among them, in order to fix the temperature sensor, a corresponding fixing clip is provided.

[0038] Therefore, when fixing the temperature sensor, it is necessary to first connect the fixing clip to the temperature sensor, and then connect the fixing clip to the condenser or the housing to achieve the installation and fixation of the temperature sensor. In this way, the fixing method of the temperature sensor is relatively cumbersome, which will reduce the assembly efficiency of the water heater.

[0039] Thus, the embodiments of the present application provide a water heater with a relatively simple fixing method for the temperature sensor, so that the water heater provided by the embodiments of the present application has a relatively high assembly efficiency.

[0040] The following will introduce the embodiments of the present application in detail with reference to the drawings and specific implementation manners.

[0041] Please refer to Figures 1 to 3 , Figure 1 which is a schematic diagram of a partial structure of the water heater provided by the embodiments of the present application, Figure 2 is Figure 1 a schematic diagram of a planar structure from another perspective, Figure 3 is Figure 1 a schematic diagram of the structure of a partial structure of . As shown in the figure, the present embodiment provides a water heater, including a housing 1, an electronic control module 2, a condenser 3, and a temperature sensor 4. Among them, a circuit board, that is, an electronic control board, can be disposed in the electronic control module 2. The electronic control module 2 controls functions such as heating, temperature adjustment, and safety protection of the water heater by receiving data from sensors and other input signals. The sensors here are not limited to the temperature sensor 4 in the present embodiment.

[0042] The condenser 3 is mainly used to improve the thermal efficiency and energy utilization efficiency of the water heater; the temperature sensor 4 is used to detect the return air temperature of the ambient air passing through the condenser 3. In this way, higher thermal efficiency and lower emissions are achieved. Specifically, the temperature sensor 4 can help detect the return air temperature to ensure that the condenser 3 can effectively recover the heat in the flue gas, thereby improving the overall thermal efficiency of the water heater. Moreover, by detecting the return air temperature, it can be ensured that the condenser 3 will not overheat, thereby avoiding damage to the water heater.

[0043] Among them, the housing 1 is a sheet metal part, and the housing 1 includes a top plate 11, a bottom plate (not shown in the figure), two first side plates 12 and two second side plates 13. The top plate 11 and the bottom plate are arranged at intervals in the height direction of the water heater. It should be noted that when the water heater is in the installed state, the top plate 11 is located above and the bottom plate is located below.

[0044] Furthermore, the two first side plates 12 are arranged opposite to each other in the first direction, and the two second side plates 13 are arranged opposite to each other in the second direction. The first direction is perpendicular to the second direction. The first direction can be the left-right direction of the water heater in the installed state, and the second direction can be the front-back direction of the water heater in the installed state. The two first side plates 12 and the two second side plates 13 are connected between the top plate 11 and the bottom plate. The top plate 11, the bottom plate, the two first side plates 12 and the two second side plates 13 enclose an installation cavity 14. The connection between the top plate 11 and the first side plate 12, between the bottom plate and the first side plate 12, between the top plate 11 and the second side plate 13, and between the bottom plate and the second side plate 13 can be achieved by welding or by connecting with threaded fasteners. Here, the connection method between the various plate parts of the housing 1 is not limited.

[0045] Among them, the electronic control module 2 and the condenser 3 are respectively located outside the two first side plates 12, and the condenser 3 is located between the top plate 11 and the bottom plate. Specifically, a part of the space between the top plate 11 and the bottom plate forms the installation cavity 14, and another part forms an installation space 15 for accommodating the condenser 3, and the installation space 15 is separated from the installation cavity 14 by a first side plate 12.

[0046] It should be noted that in order for the water heater to operate normally, a compressor 5 and the like should also be provided in the installation cavity 14. Here, other modules or structural parts included in the water heater are not specifically limited.

[0047] As can be seen from the above, in the related art, since the temperature sensor needs to be fixed by a fixing clip, the fixing steps of the temperature sensor are relatively cumbersome. Based on this, please combine Figure 4 , Figure 4 is a schematic structural diagram of a partial structure of the housing in the water heater provided by the embodiment of the present application. In Figure 4 , it can be seen that a first side plate 12 and a second side plate 13 are integrally formed. Here, the above-mentioned first side plate 12 and second side plate 13 are formed by bending a sheet metal part. Of course, in other embodiments, the first side plate 12 and the second side plate 13 can also be made of different sheet metal parts. At this time, the connection method between the first side plate 12 and the second side plate 13 can be welding or connecting together with threaded fasteners. Here, it is not limited.

[0048] In this embodiment, a limiting groove 141 is formed on the inner wall of the installation cavity 14. One end of the temperature sensor 4 is electrically connected to the electronic control module 2, and the other end passes through the limiting groove 141 and extends outside the housing 1, so that a part of the temperature sensor 4 is limited within the limiting groove 141.

[0049] In this way, through the setting of the limiting groove 141, the temperature sensor 4 can be fixed to the housing 1 to limit the relative position between the temperature sensor 4 and the housing 1. Compared with the method of fixing the temperature sensor by a fixing clip in the related art, in this embodiment, when fixing the temperature sensor 4, only a part of the temperature sensor 4 needs to be located within the limiting groove 141 and cooperate with the limiting groove 141. In this way, the fixing method of the temperature sensor 4 can be simplified, and the assembly efficiency of the water heater provided in this embodiment can be improved.

[0050] In addition, the forming of the limiting groove 141 has a lower cost compared to a fixing clip. In this way, the manufacturing cost of the water heater provided in this embodiment can also be reduced.

[0051] It can be understood that the water heater is usually fixed on an installation surface, such as a wall surface. And since the housing 1 is a sheet metal part, when forming the limiting groove 141, it is by stamping. In this way, a structure protruding towards the outside will be formed on the housing 1, and the inner side of this part of the structure corresponds to the limiting groove 141. Therefore, in order to improve the appearance performance of the water heater provided in this embodiment, the limiting groove 141 can be arranged on the part of the housing 1 facing the installation surface.

[0052] In some specific embodiments, the two second enclosing plates 13 include a rear enclosing plate 131 for facing the installation surface, and the limiting groove 141 is formed on the inner plate surface of the rear enclosing plate 131. In this way, after the limiting groove 141 is arranged on the rear enclosing plate 131, the above-mentioned structure protruding towards the outside will protrude towards the installation surface. In this way, it can, to a certain extent, avoid affecting the appearance of the water heater provided in this embodiment due to the setting of the limiting groove 141.

[0053] It should be noted that since other electrical components will also be arranged in the installation cavity 14, heat will be generated during the operation of the water heater. In some optional embodiments, in order to enable the heat to be discharged in time, heat dissipation holes 1311 communicating with the installation cavity 14 can also be arranged on the rear enclosing plate 131. In this way, heat dissipation can be carried out in time.

[0054] Of course, the setting of the heat dissipation holes 1311 may cause external dust and the like to enter the installation cavity 14 through the heat dissipation holes 1311. Therefore, in the specific implementation manner of this embodiment, a corresponding dust-proof cover 6 is provided on the outer side of each heat dissipation hole 1311. The dust-proof cover 6 extends from the top of the heat dissipation hole 1311 to the bottom end of the heat dissipation hole 1311, and forms a downwardly arranged heat dissipation opening with the heat dissipation hole 1311. In this way, not only can the heat dissipation function be realized, but also the entry of external dust and the like into the installation cavity 14 can be avoided to a certain extent.

[0055] It should be noted that the above heat dissipation opening can be formed by a combination of stamping and shearing, that is, first form the outwardly protruding dust-proof cover 6 by stamping, and then form the heat dissipation opening by shearing. Here, the process methods for forming the dust-proof cover 6 and the heat dissipation opening are not specifically limited.

[0056] As Figure 4 shown, exemplarily, in order to improve the heat dissipation performance, the heat dissipation holes 1311 can be arranged at intervals along the height direction of the water heater. Here, the number of the heat dissipation holes 1311 and the arrangement manner of the plurality of heat dissipation holes 1311 are not specifically limited.

[0057] In this embodiment, the limiting groove 141 has a first end 1411 and a second end 1412; wherein, the first end 1411 is close to the electric control module 2, and the second end 1412 is close to the condenser 3.

[0058] During the operation of the water heater, the heat in the flue gas is recovered by the condenser 3, and the water vapor in the flue gas will condense into water droplets when it meets cold in the condenser 3, which is the condensed water. The condensed water may flow back to the position where the electric control module 2 is located through the limiting groove 141, affecting the electrical performance of the electric control module 2 or causing short circuits and other phenomena.

[0059] Therefore, in order to avoid the occurrence of the above-mentioned condensed water backflow phenomenon, in this embodiment, the limiting groove 141 extends obliquely, and the second end 1412 is located below the first end 1411. In this way, the condensed water cannot flow back through the limiting groove 141 under the action of gravity, which can not only improve the use stability of the water heater provided in this embodiment, but also extend the service life of the water heater provided in this embodiment.

[0060] Please combine Figure 5 , Figure 5The figure is a schematic structural diagram of the temperature sensor in the water heater provided by the embodiment of the present application. In some specific embodiments, the temperature sensor 4 includes a sensor wire body 41 and a protective sleeve 42. The two ends of the sensor wire body 41 are respectively a connection terminal 411 and a temperature sensing probe 412, and the connection terminal 411 is electrically connected to the electronic control module 2; the protective sleeve 42 is sleeved on the sensor wire body 41, the connection terminal 411 is exposed outside the protective sleeve 42, the temperature sensing probe 412 is located inside the protective sleeve 42, and the temperature sensing probe 412 and the protective sleeve 42 together extend out of the housing 1. That is to say, the protective sleeve 42 is in direct contact with the limit groove 141.

[0061] In some embodiments, the protective sleeve 42 can be made of polyvinyl chloride (PCV) material. Here, the material of the protective sleeve 42 is not specifically limited.

[0062] Furthermore, since the temperature sensing probe 412 and the protective sleeve 42 together extend out of the housing 1, the user may accidentally touch the temperature sensing probe 412. On the one hand, it may cause harm to the user, such as electric shock, etc. On the other hand, it will affect the detection effect of the temperature sensor 4.

[0063] Therefore, in order to avoid the occurrence of the above phenomenon to a certain extent, the length of the part of the protective sleeve 42 extending out of the housing 1 in the axial direction of the protective sleeve 42 is the first length, and the length of the part of the sensor wire body 41 extending out of the housing 1 in the extending direction of the sensor wire body 41 is the second length; wherein, the first length is 5 mm to 15 mm larger than the second length. Here, the part where the first length is larger than the second length can be referred to Figure 5 as L in the figure, that is, L in the figure is greater than or equal to 5 mm and less than or equal to 15 mm.

[0064] Exemplarily, L can be 5 mm, 6 mm, 7 mm, 8 mm, 9 mm, 10 mm, 11 mm, 12 mm, 13 mm, 14 mm, 15 mm, etc. In the specific embodiment of this embodiment, the value of L is 10 mm. Here, the value of L is not specifically limited.

[0065] It can be understood that if the temperature sensing probe 412 is relatively close to the condenser 3, then under the thermal radiation of the condenser 3, the detected temperature of the temperature sensor 4 will be too high, which will affect the outlet water temperature of the water heater and the usage stability of the water heater. Therefore, in some optional embodiments, the other end of the temperature sensor 4 extends away from the condenser 3 under the squeezing action of the housing 1 and the condenser 3, where the other end of the temperature sensor 4 is the end where the temperature sensing probe 412 is located. In this way, the distance between the temperature sensing probe 412 and the condenser 3 can be avoided to a certain extent, thereby improving the detection accuracy of the temperature sensor 4 for temperature, and further improving the usage stability of the water heater provided in this embodiment.

[0066] It should be noted that when assembling the water heater provided in this embodiment, first, the rear panel 131 and the temperature sensor 4 are installed and matched. Then, the rear panel 131 is connected to other structural components included in the housing 1, and the electronic control module 2 is installed on the corresponding first panel 12. After that, the connection terminal 411 of the temperature sensor 4 is electrically connected to the electronic control module 2. Finally, the condenser 3 is installed to clamp the other end of the temperature sensor 4 between the condenser 3 and the housing 1.

[0067] If the limiting groove 141 cannot extend in the same direction, that is, if there is a bending section in the central axis of the limiting groove 141 along its own extension direction, the surface of the protective sleeve 42 will be worn at this time, affecting the protection effect of the protective sleeve 42. Therefore, in some optional embodiments, the limiting groove 141 has a central axis extending along its own extension direction, and the central axis is a straight line. In this way, the temperature sensor 4 can be prevented from being bent in the limiting groove 141 to a certain extent, which can improve the service life of the temperature sensor 4, and further improve the service life of the water heater provided in this embodiment.

[0068] Please combine Figure 3 and Figure 4 , before the temperature sensor 4 enters the limiting groove 141, the temperature sensor 4 extends in the horizontal direction. If it suddenly bends when entering the limiting groove 141, the surface of the protective sleeve 42 will be damaged. Therefore, in the specific implementation of this embodiment, the first end 1411 of the limiting groove 141 is also connected with a transition groove section 142 communicating with the limiting groove 141. The setting of the transition groove section 142 can avoid the temperature sensor 4 suddenly bending into the limiting groove 141 to a certain extent. In this way, the service life of the protective sleeve 42 can be extended, and further the service life of the temperature sensor 4 can be extended, so as to extend the service life of the water heater provided in this embodiment.

[0069] As described above, since the temperature sensor 4 is used to detect the return air temperature of the ambient air flowing through the condenser 3, the temperature sensing probe 412 needs to be arranged close to the condenser 3. In this embodiment, the rear enclosure 131 has a stop surface 1312 facing the condenser 3, and the second end 1412 is formed on the stop surface 1312. In this way, the second end 1412 is formed on the end surface of the rear enclosure 131 close to the condenser 3, so that the temperature sensing probe 412 is relatively close to the condenser 3, thereby improving the detection accuracy of the temperature sensor 4.

[0070] However, since there is still a certain distance between the electronic control module 2 and the first end 1411 of the limit groove 141, if there is no additional structure to cooperate with and connect to the temperature sensor 4 during this process, on the one hand, it may cause the temperature sensor 4 to separate from the electronic control module 2 under the action of gravity, and on the other hand, it may cause interference between the temperature sensor 4 and other structures in the installation cavity 14.

[0071] Therefore, please refer to Figure 6 and Figure 7 , Figure 6 which is a three-dimensional structural schematic diagram of the flexible wire threading member in the water heater provided by the embodiment of the present application. Figure 7 It is Figure 6 a three-dimensional structural schematic diagram from another perspective. In some embodiments, the water heater provided in this embodiment further includes a flexible wire threading member 7. The flexible wire threading member 7 is connected to the housing 1 and is located in the installation cavity 14. A wire passing hole 71 is formed on the flexible wire threading member 7; one end of the temperature sensor 4 passes through the wire passing hole 71 and is electrically connected to the electronic control module 2.

[0072] In order to fix the flexible wire threading member 7, in this embodiment, a fixing plate 16 is provided at the corner of the rear enclosure 131 and the first enclosure 12 for fixing the electronic control module 2, and the flexible wire threading member 7 is connected to the fixing plate 16.

[0073] Furthermore, the flexible wire threading member 7 includes an annular connecting portion 72. Four wire threading portions 73 are connected to the inner side of the annular connecting portion 72. The wire passing hole 71 is formed at the junction of the four wire threading portions 73. An annular wire passing portion 74 is also connected to the annular connecting portion 72, and the axial length of the annular wire passing portion 74 is greater than that of the annular connecting portion 72. The temperature sensor 4 can sequentially pass through the annular wire passing portion 74 and the wire passing hole 71 and be electrically connected to the electronic control module 2.

[0074] In order to realize the connection between the flexible wire threading member 7 and the fixing plate 16, a fixing hole 161 matching the annular connecting portion 72 can be provided on the fixing plate 16. Through the connection between the annular connecting portion 72 and the fixing hole 161, the connection between the flexible wire threading member 7 and the fixing plate 16 can be realized.

[0075] In this embodiment, in order to improve the structural strength of the flexible wire threading member 7 and to improve the installation convenience of the flexible wire threading member 7, lugs 75 with openings are provided on opposite sides of the annular wire passing portion 74. In this way, on the one hand, the structural strength of the flexible wire threading member 7 can be improved, and on the other hand, the two lugs 75 can be grasped by hand for installation; in addition, external wires can pass through the lugs 75 for electrical connection, facilitating wiring.

[0076] The above are only the preferred embodiments of the present application, and do not limit the patent scope of the present application. Any equivalent structural transformation made under the concept of the present application by using the content of the specification and drawings of the present application, or direct / indirect application in other related technical fields, is included in the patent protection scope of the present application.
