Description

Technical Field

[0001] This utility model relates to the field of heat exchange system technology, and in particular to a temperature measuring component and a water heater. Background Technology

[0002] To ensure efficient and safe operation of the heat exchange system and extend its service life, temperature sensors are typically installed on the heat exchangers of heat pump water heaters. The main function of these sensors is to detect the actual temperature of the surrounding environment, allowing the heat exchange system to effectively adjust and operate according to changes in external conditions. Accurate temperature information is crucial for the normal operation of the heat exchange system; if the temperature sensor malfunctions, the system may fail to reach the set temperature or trigger unnecessary shutdowns and fault alarms due to falsely detecting high temperatures, thus interfering with the normal use of the heat exchange system.

[0003] Traditionally, temperature measuring components are fixedly mounted on the metal plate (sheet metal part) of the heat exchanger housing in water heaters. However, this mounting method has certain limitations. For example, when exposed to outdoor environments, especially under direct sunlight, the sheet metal part itself easily heats up due to heat absorption. This causes the temperature measured by the measuring component to be the temperature of the sheet metal part after being heated, rather than the true ambient temperature. Therefore, temperature sensors installed in this way may provide inaccurate temperature readings in certain situations, leading to system misjudgments and unnecessary fault reports. Utility Model Content

[0004] The main purpose of this utility model is to propose a temperature measuring component and a water heater, which aims to solve the problem that the existing temperature measuring components are prone to inaccurate temperature measurement.

[0005] To achieve the above objectives, the present invention proposes a temperature measuring component for use in a water heater, the temperature measuring component comprising:

[0006] The main body has a mounting cavity, the cavity wall of which is provided with an air inlet and an air outlet. A protrusion is provided inside the mounting cavity, defining a connecting channel within the mounting cavity that communicates with the air inlet and the air outlet and is at least partially curved.

[0007] A temperature sensor is disposed within the mounting cavity, and at least its temperature measuring part is disposed in the communicating channel.

[0008] In one embodiment, the connecting channel is formed with a narrow opening.

[0009] In one embodiment, a plurality of annular ribs are formed in the mounting cavity, adjacent annular ribs define an annular channel, and an opening is formed on the side of the annular channel, the opening forming the narrow opening;

[0010] The annular channel is connected to the air inlet and the air outlet.

[0011] In one embodiment, the body includes:

[0012] The base plate has a mounting groove recessed on one side in the first direction; and,

[0013] A cover plate is provided to cover the opening of the mounting groove so as to form the mounting cavity with the base plate;

[0014] The cover plate and the base plate are respectively provided with the air inlet and the air outlet, which are staggered.

[0015] In one embodiment, the air inlet is configured as a circular hole; and / or,

[0016] The air outlet is configured as a strip-shaped hole.

[0017] In one embodiment, the protrusion includes a first annular rib and a second annular rib respectively disposed on the cover plate and the bottom plate, the first annular rib and the second annular rib being staggered.

[0018] In one embodiment, the temperature measuring unit is staggered from the air inlet and the air outlet.

[0019] In one embodiment, the cover plate is disposed at one end of the base plate in a second direction, and the cover plate is rotatably connected to the base plate about a rotation axis in a third direction.

[0020] In one embodiment, the base plate and the cover plate are integrally formed.

[0021] In one embodiment, the main body includes a main body segment and a mounting segment arranged sequentially along a second direction, wherein the mounting cavity is formed within the main body segment;

[0022] The temperature measuring component also includes a mounting structure disposed in the mounting section, the mounting structure being used for mounting to the casing of the water heater.

[0023] In one embodiment, the mounting structure includes a retaining portion for engaging with a slot on the housing.

[0024] In one embodiment, at least two retaining portions are provided, and the two retaining portions are spaced apart in the second direction;

[0025] One of the two holding parts includes a connecting part extending outward from the mounting section and a mating part extending from the connecting part along the second direction, wherein the mating part is provided with a guide slope on the side facing the mounting section.

[0026] This utility model also proposes a water heater, which includes a temperature measuring component, the temperature measuring component comprising:

[0027] The main body has a mounting cavity, the cavity wall of which is provided with an air inlet and an air outlet. A protrusion is provided inside the mounting cavity, defining a connecting channel within the mounting cavity that communicates with the air inlet and the air outlet and is at least partially curved.

[0028] A temperature sensor is disposed within the mounting cavity, and at least its temperature measuring part is disposed in the communicating channel.

[0029] In the technical solution of this utility model, by setting an air inlet and an air outlet on the cavity wall of the mounting cavity, as well as a connecting channel connecting the air inlet and the air outlet, airflow can enter into the mounting cavity and exchange heat with the channel wall. By setting a protrusion, the path of the connecting channel is bent, and the contact area and heat conduction path between the airflow and the sheet metal part when flowing in the connecting channel are further weakened. This allows the temperature measuring part of the temperature sensor to more accurately reflect the real ambient temperature, rather than the false high temperature caused by local heating on the surface of the sheet metal part. This solves the problem of temperature mismeasurement caused by direct attachment of traditional temperature measuring components to the casing, reduces the downtime failure rate caused by high temperature misjudgment, and improves the response accuracy of the heat exchange system of the water heater to ambient temperature.

[0049] Traditionally, temperature measuring components are fixedly mounted on the metal plate (sheet metal part) of the heat exchanger housing in a heat pump water heater. However, this mounting method has certain limitations. For example, when exposed to outdoor environments, especially under direct sunlight, the sheet metal part itself easily heats up due to heat absorption. This causes the temperature measured by the measuring component to be different from the true ambient temperature, instead reflecting the temperature of the sheet metal part after being heated. Therefore, temperature sensors installed in this way may provide inaccurate temperature readings in certain situations, leading to system misjudgments and unnecessary fault reports.

[0050] This invention proposes a temperature measuring component, which aims to solve the problem of inaccurate temperature measurement that often occurs with existing temperature measuring components.

[0051] Please see Figures 1 to 3 In one embodiment of this utility model, the temperature measuring component 100 is used in a water heater. The temperature measuring component 100 includes a main body 10 and a temperature sensor 20. The main body 10 has a mounting cavity a. An air inlet b and an air outlet c are provided on the cavity wall of the mounting cavity a. A protrusion is provided inside the mounting cavity a. The protrusion defines a connecting channel d that connects the air inlet b and the air outlet c and is at least partially curved. The temperature sensor 20 is located inside the mounting cavity a, and at least its temperature measuring part is located in the connecting channel d.

[0052] It is understood that the main body 10 of the temperature measuring component 100 is a shell structure, which has an installation cavity a inside. The cavity wall of the installation cavity a has an air inlet b and an air outlet c, and a protrusion is provided on the inner side of the cavity wall. The protrusion extends along the inner wall of the installation cavity a, divides the space inside the installation cavity a, and defines a connecting channel d that connects the air inlet b and the air outlet c. This channel has a path that is at least partially curved, such as an "S" shape, a ring shape, or a zigzag shape.

[0053] By setting a protrusion in the mounting cavity a, the flow path of the external airflow in the channel can be extended as much as possible, so that the airflow gradually exchanges heat with the channel wall during the flow process, rather than the sheet metal parts of the heat exchanger housing of the water heater, thereby reducing the interference of the high temperature of the housing on the temperature measurement.

[0054] Temperature sensor 20 is located inside the mounting cavity a, and its temperature measuring part is located inside the connecting channel d, on the airflow path between the air inlet b and the air outlet c. By placing the temperature measuring part inside the channel, it can directly contact the external ambient airflow, rather than directly contacting the sheet metal parts of the water heater heat exchanger casing, thereby avoiding the problem of artificially high temperature caused by sunlight radiation or heat conduction on the sheet metal parts.

[0055] It should be noted that the main body 10 is mounted on the surface of the sheet metal casing of the water heater heat exchanger via a fixed structure, but a predetermined air inlet gap is maintained between the air inlet b and the sheet metal casing. When the water heater heat exchanger is running, ambient air enters the air inlet b through the air inlet gap, flows along the curved connecting channel d, and is finally discharged from the air outlet c. It is understood that because a predetermined air inlet gap is maintained between the air inlet b and the sheet metal casing, there is a gap between the main body 10 and the casing of the water heater heat exchanger, at least in the portion corresponding to the mounting cavity a. This also helps to minimize the direct transfer of heat from the sheet metal casing to the temperature measuring unit through the cavity wall of the mounting cavity a, reducing false readings.

[0056] It should also be noted that, in order to detect the ambient temperature at the heat exchanger of the water heater as accurately as possible, the temperature measuring component 100 is set at the opening of the casing of the water heater heat exchanger, and the opening of the casing is set at the exhaust fan of the water heater heat exchanger. The air flow speed is relatively fast here, so the temperature measuring component 100 can make better use of the airflow at the opening of the casing of the water heater heat exchanger for detection.

[0057] In the technical solution of this utility model, by setting an air inlet b and an air outlet c on the cavity wall of the mounting cavity a, and a connecting channel d connecting the air inlet b and the air outlet c, airflow can enter the mounting cavity a and exchange heat with the channel wall. By setting a protrusion, the path of the connecting channel d is bent, and the contact area and heat conduction path between the airflow and the sheet metal part when flowing in the connecting channel d are further weakened. This allows the temperature measuring part of the temperature sensor 20 to more accurately reflect the real ambient temperature, rather than the false high temperature caused by local heating on the surface of the sheet metal part. This solves the problem of temperature mismeasurement caused by the direct attachment of the traditional temperature measuring component 100 to the casing, reduces the downtime failure rate caused by high temperature misjudgment, and improves the response accuracy of the heat exchange system of the water heater to the ambient temperature.

[0058] Furthermore, in this embodiment, the connecting channel d is formed with a narrow opening.

[0059] When a narrow opening is set, based on the Venturi effect, the airflow velocity increases and the pressure decreases when the airflow passes through the area with a reduced cross-sectional area. Specifically, setting a narrow opening structure in the connecting channel d can increase the airflow velocity through this section, thereby improving the heat exchange efficiency between the airflow and the temperature sensing part of the temperature sensor 20, ensuring that the temperature sensing part can sense changes in the external ambient temperature more quickly and accurately.

[0060] Furthermore, because the accelerated airflow can carry away heat from the channel more quickly, it also helps maintain the stability of the temperature inside the entire connecting channel, reducing the impact of external factors on the temperature measurement results. The position and size of the narrow opening can be adjusted according to actual needs to achieve the best airflow acceleration effect and temperature measurement accuracy.

[0061] Specifically, in this embodiment, a plurality of annular ribs 30 are formed in the mounting cavity a, and adjacent annular ribs 30 define an annular channel; the annular channel is connected to the air inlet b and the air outlet c, and an opening is provided on the side of the annular channel, the opening forming the narrow opening.

[0062] Multiple annular ribs 30 are formed inside the mounting cavity a. The annular ribs 30 are configured to be evenly distributed along the inner wall of the mounting cavity a, serving to separate and guide the airflow path, while increasing the contact area between the airflow and the channel wall, thus helping to improve heat exchange efficiency.

[0063] An annular channel is defined between adjacent annular ribs 30 to make the airflow direction smoother and more orderly, and to increase the airflow path length to improve the heat exchange effect between the airflow and the temperature measuring part of the temperature sensor 20.

[0064] An opening is provided on the side of the annular channel. The opening serves to connect different annular channel regions. When airflow passes through the opening, the airflow velocity increases significantly due to the sudden decrease in cross-sectional area.

[0065] It should be noted that the narrow opening can also serve as a passage for the power wire of the temperature sensor 20. The side wall of the narrow opening can be configured to have an interference fit with the power wire to position the power wire.

[0066] Specifically, in this embodiment, the main body 10 includes a base plate 1 and a cover plate 2. The base plate 1 has a recessed mounting groove 1a on one side in the first direction. The cover plate 2 covers the opening of the mounting groove 1a to form the mounting cavity a with the base plate 1. The cover plate 2 and the base plate 1 are respectively provided with the air inlet b and the air outlet c, and the air inlet b and the air outlet c are staggered.

[0067] The main body 10 includes a base plate 1, on one side of which a mounting groove 1a is recessed. The mounting groove 1a is used to accommodate the temperature sensor 20 and other necessary components, and guides the airflow through a protrusion located inside it to ensure the accuracy of temperature measurement.

[0068] The cover plate 2 is placed over the opening of the mounting groove 1a, and together with the base plate 1, forms the mounting cavity a. The cover plate 2 not only seals the mounting groove 1a, but also works with other components to ensure that the entire temperature measuring assembly 100 has good sealing performance and structural stability.

[0069] It should be noted that the air inlet b and air outlet c are respectively located on the cover plate 2 and the base plate 1, and are at least partially staggered in the second and / or third directions. When airflow enters from the air inlet b on the cover plate 2, it will not directly pass through to the other side of the base plate 1 and be quickly lost. Instead, due to the staggered arrangement of the air inlet b and air outlet c, the airflow will first encounter the base plate 1 or other internal structures as a stop after entering the mounting cavity a, resulting in a sudden increase in air pressure. At this time, the airflow is forced to change direction and diffuse to the surroundings, especially towards the connecting channel d.

[0070] This configuration ensures that the airflow fully enters and fills the entire connecting channel d, increasing the contact opportunities and time between the airflow and the temperature sensor 20, thereby improving the accuracy of temperature measurement.

[0071] Specifically, in this embodiment, the air inlet b is configured as a circular hole; and / or, the air outlet c is configured as a strip-shaped hole.

[0072] The air inlet b is designed as a round hole, which makes the airflow more stable and reduces the resistance and turbulence formation when the airflow enters, thus making the airflow entering the mounting cavity a more stable and uniform.

[0073] Understandably, the air outlet c is designed as a strip-shaped hole, unlike the round air inlet b. The strip-shaped hole as the air outlet c has a larger outlet area, which is conducive to the rapid discharge of air and reduces internal pressure. In addition, the shape of the hole alone can create a misalignment between the air inlet b and the air outlet c, at least partially in a second direction and / or a third direction.

[0074] It should be noted that the diameter of the circular orifice can be adjusted according to actual needs to accommodate different airflow requirements, ensuring that ambient air can effectively flow into the connecting channel d. The length and width of the strip orifice can also be flexibly adjusted according to specific application needs to optimize the airflow discharge path.

[0075] Specifically, in this embodiment, the protrusion includes a first annular rib 31 and a second annular rib 32 respectively disposed on the cover plate 2 and the bottom plate 1, wherein the first annular rib 31 and the second annular rib 32 are staggered.

[0076] Understandably, the first annular rib 31 is located on the cover plate 2, while the second annular rib 32 is located on the base plate 1. The two ribs together form a connecting channel d with a specific path inside the mounting cavity a to guide airflow and optimize heat exchange efficiency.

[0077] The first annular rib 31 and the second annular rib 32 are staggered in the second direction and / or the third direction. That is, the first annular rib 31 and the second annular rib 32 are not aligned in the second direction and / or the third direction, but are staggered along the direction of airflow entry. This creates gaps between them, guiding the airflow along a more circuitous path instead of directly passing through the mounting cavity a. Thus, when the airflow enters from the air inlet b, it is forced to change direction upon encountering the first annular rib 31 and the second annular rib 32 due to their positional difference, increasing the complexity and length of the airflow path.

[0078] Furthermore, since most heat exchangers for water heaters are installed outdoors, when it rains or snows, rain and snow may enter the installation cavity a from the air inlet b and the air outlet c, and fall on the temperature measuring unit. In this case, the temperature detected by the temperature measuring unit will be the temperature of the rain and snow, which will also lead to inaccurate temperature measurement. In order to avoid the temperature measuring component 100 being affected by rain and snow, in this embodiment, the temperature measuring unit is staggered from the air inlet b and the air outlet c.

[0079] Thus, the temperature measuring unit is staggered from the air inlet b and the air outlet c in the second direction and / or the third direction, ensuring that the temperature measuring unit is not directly located on the straight line of airflow entering from the air inlet b or exiting from the air outlet c. Instead, the staggered arrangement of the positions makes the temperature measuring unit a safer position.

[0080] Specifically, when there is precipitation in the external environment, due to the staggered arrangement of the air inlet b and the temperature measuring unit in the second and / or third directions, the rainwater will first be blocked or guided away from its original path by the structure around the air inlet b, and will not flow in a straight line to the temperature measuring unit. Similarly, even if a small amount of moisture enters the installation cavity a through the air inlet b, since the temperature measuring unit is not directly located behind the inlet, the moisture will not easily reach the temperature measuring unit directly.

[0081] Specifically, in this embodiment, the cover plate 2 is disposed at one end of the base plate 1 in the second direction, and the cover plate 2 is rotatably connected to the base plate 1 about a rotation axis in the third direction.

[0082] The cover plate 2 is connected to the base plate 1 via a rotating shaft arranged along a third direction. It should be noted that the first direction, the second direction, and the third direction are arranged in pairs, that is, if the first direction is set to left and right, then the second direction is set to front and back, and the third direction is set to up and down.

[0083] By employing a rotating connection, opening and closing the cover plate 2 relative to the base plate 1 becomes much simpler. When it is necessary to install, debug, or maintain components, the cover plate 2 can be opened with a simple rotation, thus providing easy access to the various components within the mounting cavity a.

[0084] Furthermore, in this embodiment, the base plate 1 and the cover plate 2 are integrally formed.

[0085] The base plate 1 and the cover plate 2 are integrally formed, meaning that the base plate 1 and the cover plate 2 are manufactured as a single unit through injection molding or other molding processes during production. This simplifies the production process, reduces assembly steps, and improves production efficiency.

[0086] It is understandable that, in order to enable the cover plate 2 to rotate relative to the base plate 1, one or more grooves can be set at the predetermined axis of rotation to reduce the material thickness in that area, making the thickness thinner and forming a natural axis of rotation.

[0087] This design eliminates the need for additional metal or other material shafts, further simplifying the manufacturing process and reducing costs. The cover plate 2 can rotate freely within a certain range, facilitating opening and closing operations while also ensuring the structural integrity and stability.

[0088] Specifically, in this embodiment, the main body 10 includes a main body segment 11 and an installation segment 12 arranged sequentially along the second direction, and the installation cavity a is formed in the main body segment 11; the temperature measuring component 100 also includes an installation structure 40 disposed in the installation segment 12, and the installation structure 40 is used for installation with the housing of the water heater heat exchanger.

[0089] It is understood that the main body 10 is divided into two parts: the main body section 11 and the mounting section 12. The main body section 11 is used to house the temperature sensor 20 and other necessary components, while the mounting section 12 is used to fix and connect to the housing of the water heater heat exchanger.

[0090] An installation structure 40 is also provided on the installation section 12. The installation structure 40 is used for mounting to the housing of the water heater heat exchanger, so as to quickly and securely install the temperature measuring component 100 onto the housing of the water heater heat exchanger. It should be noted that the installation structure 40 can be a screw, a clip, or other possible shapes. The specific design can be determined according to the actual situation, and this specification does not limit this embodiment.

[0091] With this configuration, the mounting structure 40 is placed on the mounting section 12 instead of the main body section 11, so that the heat from the heat exchanger's casing sheet metal parts will not be directly transferred to the main body section 11. The mounting section 12, as part of the thermal insulation, can effectively reduce the heat conducted from the casing to the main body section 11.

[0092] It should also be noted that the structure of the mounting section 12 can be adjusted according to actual conditions to ensure that the main body section 11 is as far away from the sheet metal parts as possible after installation. In practical applications, depending on the different models of the water heater heat exchangers or the installation environment, the distance between the main body section 11 and the casing can be increased by adjusting the length and shape of the mounting section 12. This further reduces the impact of the high temperature on the casing surface on the temperature measuring component 100, ensuring that the temperature sensor 20 can operate under conditions closer to the actual ambient temperature and improving measurement accuracy.

[0093] Specifically, in this embodiment, the mounting structure 40 includes a retaining part 41 for engaging with the slot e on the housing.

[0094] The retaining part 41 engages with the retaining slot e on the housing to achieve a quick and secure connection with the pre-set retaining slot e on the housing of the water heater heat exchanger.

[0095] The installation process of the temperature sensing component 100 is simplified by the engaging engagement between the retaining part 41 and the retaining slot e. Users can complete the installation without additional tools or complicated steps, improving installation efficiency. Furthermore, the temperature sensing component 100 can be easily disassembled for maintenance or replacement when necessary, increasing flexibility and convenience of use.

[0096] It should be noted that the retaining part 41 has a specific shape and size to facilitate insertion into the card slot e of the housing and to ensure a secure connection through elastic deformation or mechanical locking. For example, the retaining part 41 can be designed as an arm-shaped structure with a certain degree of elasticity. When inserted into the card slot e, these arms will bend slightly to adapt to space constraints and then return to their original shape to form a tight connection.

[0097] Specifically, in some embodiments, at least two retaining portions 41 are provided, and the two retaining portions 41 are spaced apart in the second direction; one of the two retaining portions 41 includes a connecting portion 411 extending outward from the mounting section 12, and a mating portion 412 extending from the connecting portion 411 along the second direction, and the mating portion 412 is provided with a guide slope 4121 on the side facing the mounting section 12.

[0098] More specifically, in the first embodiment, at least two retaining parts 41 are provided, and the two retaining parts 41 are spaced apart in the second direction. This ensures that the temperature measuring component 100 can be securely installed on the housing of the water heater heat exchanger, avoiding instability or displacement caused by single-point fixing.

[0099] For ease of installation, one of the two retaining portions 41 includes a connecting portion 411 extending outward from the mounting section 12 and a mating portion 412 extending outward from the connecting portion 411 in a second direction. The mating portion 412 has a guide slope 4121 on the side facing the mounting section 12. Specifically, a retaining portion 41 with a guide slope 4121 is provided at a position away from the main body section 11, and this retaining portion 41 extends outward. Thus, the guide slope 4121 can guide the retaining portion 41 smoothly into the corresponding slot e on the housing, reducing resistance and friction during assembly.

[0100] Another retaining part 41 can be configured as a hook. During assembly, first insert the retaining part 41 that is away from the main body section 11, i.e., the retaining part 41 with the guide slope 4121, into the corresponding slot e. Then, by pressing down on the hook of the retaining part 41 located near the main body section 11, it is also firmly engaged into the corresponding slot e.

[0101] In the second embodiment, at least two retaining portions 41 are also provided, and the two retaining portions 41 are also spaced apart in the second direction. Unlike the first embodiment, in this embodiment, the retaining portion 41 with the guide slope 4121 is located close to the main body segment 11, and the guide slope 4121 faces the other retaining portion 41 rather than away from it.

[0102] Another retaining part 41 is configured as a hook. During assembly, first insert the retaining part 41 closest to the main body section 11, i.e., the retaining part 41 with the guide slope 4121, into the corresponding slot e. Then, press down on the hook of the retaining part 41 located away from the main body section 11 to complete the entire installation process.

[0103] By rationally arranging the number and position of the holding parts 41, different installation requirements can be met, ensuring both the convenience and stability of installation, and improving the reliability and maintainability of the overall system.

[0104] This utility model also proposes a water heater, which is configured as a heat pump type water heater. The water heater includes a casing and a temperature measuring component 100. The specific structure of the temperature measuring component 100 is as described in the above embodiments. Since the heat exchanger of this water heater adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.

[0105] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
