[0039] like Figures 1 to 9 As shown, an embodiment of the present application provides an air-heating module for a water heater, and the air-heating module 20 includes: a shell 100, connected to the main body 10 of the water heater, the shell 100 is provided with a first air inlet 101, a second air inlet 102 and an air outlet 103 which are connected to each other, the first air inlet 101 and the second air inlet 102 are arranged at the same side of the shell 100 along the length direction Y of the shell 100, and the first air inlet 101 and the air outlet 103 are arranged at opposite sides of the shell 100 along the width direction X of the shell 100; a first fan assembly 200, corresponding to the first air inlet 101, is arranged in the shell 100; a second fan assembly 300, corresponding to the second air inlet 102, is arranged in the shell 100; a heating element 400, arranged at the air outlet end of the first fan assembly 200 and the second fan assembly 300; and an over-protection assembly 500, which is arranged in the shell 100, and the over-protection assembly 500 is configured to detect the ambient temperature around the heating element 400.
[0040] Compared with the traditional method of configuring the air-heating module inside the water heater, the technical solution of the present application integrates the air-heating module 20 outside the water heater body 10. The external air-heating module 20 can at least reduce the accommodation space of the water heater body 10 for assembling the air-heating module 20, reduce the overall volume of the body 10, and reduce the occupied space of the water heater; at the same time, the external air-heating module 20 can effectively avoid the interference of water vapor in the body 10, and improve the safety of the use of the air-heating module 20. In addition, the technical solution of the present application can realize basic hot water supply through the body 10 of the heat exchanger, and realize warm air supply through the air-heating module 20, thereby enriching the function of the water heater and improving the user's experience. In addition, the air inlet and air outlet of the air-heating module 20 are arranged in the width direction X of the shell 100, while increasing the ventilation area of the air inlet and air outlet to increase the air volume in and out of the air-heating module 20, the layout of the air-heating module 20 is compact, and the occupied space is small, which is conducive to the miniaturization layout of the air-heating module 20. In this way, the present application reduces the space occupied by the water heater and promotes the miniaturization of the water heater at least in two aspects, namely reducing the volume of the water heater body 10 and reducing the volume of the air heating module 20. In addition, the water heater provided not only provides basic hot water, but also has a heating function, and is rich in functions and has a wide range of applications.
[0041] Specifically, the air-heating module 20 is configured as a composite component including at least a housing 100, a first fan assembly 200, a second fan assembly 300, a heating element 400 and an over-protection assembly 500. The housing 100 can be a flat box-shaped structure approximately in the shape of a concave letter, and the first air inlet 101 and the second air inlet 102 thereon are arranged at intervals at both ends of the housing 100 along the length direction Y of the housing 100. The first air inlet 101 and the second air inlet 102 can be arranged at two protruding portions of the concave letter. The first fan assembly 200 can be arranged on the side of the housing 100 to guide the gas at different positions into the air-heating module 20 at least in the length direction Y of the housing 100, thereby increasing the air inlet area, increasing the air inlet flow rate, ensuring the warm air supply volume at the air outlet end, improving the warm air supply effect, and improving the user experience; the air outlet 103 thereon extends along the length direction Y of the housing 100 and can be distributed on the long side of the concave shape, and the air outlet 103 can pass through the entire long side of the concave shape to increase the air outlet area, improve the air outlet flow rate and the warm air effect. The first fan assembly 200 can be a centrifugal fan with a volute, and the volute and the upper and lower end surfaces of the housing 100 are enclosed to form a first air duct, and the air inlet of the volute is connected to the first air inlet 101, so that the gas outside the first air inlet 101 can be sucked into the volute by the centrifugal fan to form a first cold air flow. The second fan assembly 300 can be a centrifugal fan with a volute, which encloses the upper and lower end surfaces of the volute and the shell 100 to form a second air duct, and the air inlet of the volute is connected to the second air inlet 102. In this way, the gas outside the second air inlet 102 can be sucked into the volute through the centrifugal fan to form a second cold air flow; the second fan assembly 300 and the first fan assembly 200 are arranged on both sides of the inner Dan water nozzle, which can ensure uniform air outlet on the left and right, save the installation space in the thickness direction Z of the shell 100, and reduce the volume of the air heating module 20. The heating element 400 may be a PTC heater, which may be a plate-like structure, embedded between the upper and lower end surfaces of the shell 100. It should be noted that at least the material of the connection between the shell 100 and the heating element 400 must be flame-retardant material to prevent the heating element 400 from burning the shell 100; the heating element 400 is arranged on the air outlet side of the volute, and is embedded in the shell 100 along the thickness direction Z of the shell 100 to separate the shell 100 into a cold air zone and a warm air zone, and the first air duct and the second air duct can be heated together by the heating element 400 after converging on the cold air zone side, and flow out of the air-heating module 20 from the air outlet 103; of course, the first air duct and the second air duct can also pass through the heating element 400 separately and be heated, and then flow out of the air-heating module 20 from the air outlet 103 after converging in the warm air zone.The over-voltage protection component 500 can be a temperature sensor for detecting the ambient temperature around the heating element 400. When the temperature near the heating element 400 is too high, the heating element 400 is controlled to stop working to prevent the heating temperature provided by the air heating module 20 from being too high and scalding the user, thereby improving the safety of use; and when the temperature near the heating element 400 is too low, the heating element 400 is controlled to heat again to provide warm air to the user, thereby improving the user experience.
[0042] In addition, in order to prevent the bathing water provided by the heater body 10 from spraying into the air heating module 20, the first air inlet 101 and the second air inlet 102 can be arranged toward the wall, thereby improving the safety and service life of the air heating module 20.
[0043] In one example, the water heater body 10 and the air heating module 20 share a main control board, which is arranged on the water heater body 10 and integrates a control circuit for heating water and a control circuit for providing warm air. The heating element 400 and the over-protection component 500 are electrically connected to the main control board, which is used to receive and process the ambient temperature detected by the over-protection component 500, and control whether the heating element 400 continues the heating operation according to the ambient temperature information.
[0044] In one example, the first fan assembly 200 and the second fan assembly 300 are powered by low-voltage direct current, and the power supply voltage is preferably DC 12V~24V; the two can be connected in series. Once one of the fan assemblies is damaged, the other fan assembly will also suspend operation. In this way, overheating protection of the air heating module 20 is achieved, and the operating safety of the air heating module 20 is improved.
[0045] like Figure 1 , Figure 2 and Figure 4 As shown, in a possible embodiment, the over-protection component 500 includes a first connecting seat 510 and a first detection component 520 arranged on the first connecting seat 510, the first connecting seat 510 extends along the length direction Y of the shell 100, and is connected to the shell 100 corresponding to the air outlet end of the first fan assembly 200, and the first detection component 520 is used to detect the first ambient temperature around the corresponding heating element 400.
[0046] In this embodiment, the specific configuration of the over-protection component 500 is optimized. Specifically, the over-protection component 500 is configured as a combined component including at least a first connection seat 510 and a first detection member 520. The first connection seat 510 can be a special-shaped long plate-like structure, one end of which is connected to the shell 100, and the other end extends toward the center line of the shell 100 along the length direction Y of the shell 100. In this way, the first detection member 520 is configured at a position close to the center line of the shell 100, thereby improving the sensitivity and accuracy of temperature detection. The first detection component 520 can be a temperature control sensor, which can be connected to the first connecting seat 510 by bonding or clamping; the first detection component 520 can be set in the cold air zone facing the first fan assembly 200, for detecting the temperature on the cold air zone side of the heating component 400. At this time, the first preset temperature of the first detection component 520 should be smaller; or, the first detection component 520 can be set in the warm air zone away from the first fan assembly 200, for detecting the temperature on the warm air zone side of the heating component 400. At this time, the first preset temperature of the first detection component 520 should be larger; when the first ambient temperature on the warm air zone side is greater than or equal to the first preset temperature, it means that the temperature of the warm air flowing out of the warm air zone side is too high, and heating needs to be stopped to prevent the overheated warm air from scalding the user.
[0047] In addition, the first detection member 520 should be electrically connected to the main control board of the water heater, so that the main control board can receive and process the detection data from the first detection member 520, and then control the heating member 400 to perform the heating operation according to the detection data. When it is detected that the first ambient temperature around the heating member 400 is greater than or equal to the first preset temperature, the heating member 400 is controlled to stop heating; when it is detected that the first ambient temperature around the heating member 400 is less than the first preset temperature, the heating member 400 is controlled to continue or heat again.
[0048] like Figure 4 As shown, in a possible embodiment, the first connecting seat 510 includes a first connecting plate 511 and a first hollow plate 512 connected to the free end of the first connecting plate 511, and the end of the first connecting plate 511 away from the first hollow plate 512 is detachably connected to the shell 100, and the plane where the first hollow plate 512 is located is set at an angle to the plane where the first connecting plate 511 is located; the first detection element 520 is arranged on the first hollow plate 512, and the heating element 400 is connected to the shell 100 through the first connecting plate 511.
[0049] In this embodiment, the specific configuration of the first connection seat 510 is optimized. Specifically, the first connection seat 510 is configured as a composite component including at least a first connection plate 511 and a first hollow plate 512. The first connection plate 511 can be a bent long narrow plate, one end of which can be connected to the housing 100 by fasteners such as screws / bolts, and the other end is used to connect the first hollow plate 512; the side of one end of the first hollow plate 512 can be vertically connected to the side of the free end of the first connection plate 511. The inner angle for avoiding the heating element 400 is formed between the first hollow plate 512 and the first connection plate 511. In this way, the first detection member 520 arranged on the first hollow plate 512 can be distributed on the air outlet side or the air inlet side of the heating element 400, thereby improving the detection sensitivity and detection accuracy, and ensuring the safe operation of the air heating module 20. One end of the heating element 400 in the length direction Y of the shell 100 can be connected to the first connecting plate 511 to further enhance the connection tightness between the heating element 400 and the over-protection component 500 .
[0050] In addition, the first hollow plate 512 is provided with hollow holes, which can not only reduce the overall weight of the first connecting seat 510 and realize the lightweight layout of the first connecting seat 510; but also reserve installation space for the first detection component 520, reduce the occupied volume of the over-protection component 500, and realize the compact and miniaturized layout of the over-protection component 500.
[0051] like Figure 1 , Figure 2 and Figure 5 As shown, in a possible implementation, the over-protection component 500 also includes a second connecting seat 530 and a second detection component 540 arranged on the second connecting seat 530, the second connecting seat 530 extends along the length direction Y of the shell 100, and is connected to the shell 100 corresponding to the air outlet end of the second fan assembly 300, and the second detection component 540 is used to detect the first ambient temperature around the corresponding heating element 400.
[0052] In this embodiment, the specific configuration of the over-protection component 500 is further optimized. Specifically, the over-protection component 500 is configured as a composite component including at least a first connection seat 510, a first detection member 520, a second connection seat 530 and a second detection member 540. The second connection seat 530 can be a special-shaped long plate-like structure, one end of which is connected to the shell 100, and the other end extends toward the center line of the shell 100 along the length direction Y of the shell 100. In this way, the second detection member 540 is configured at a position close to the center line of the shell 100 to improve the sensitivity and accuracy of temperature detection; the second connection seat 530 and the first connection seat 510 are respectively arranged on opposite sides of the heating element 400 along the length direction Y of the shell 100. The second connection seat 530 can be arranged opposite to the first connection seat 510, or it can be arranged offset with the first connection seat 510. The second detection component 540 can be a temperature control sensor, which can be connected to the second connecting seat 530 by bonding or clamping; the second detection component 540 can be set in the cold air zone facing the second fan assembly 300, for detecting the temperature on the cold air zone side of the heating component 400. At this time, the first preset temperature of the second detection component 540 should be smaller; or, the second detection component 540 can be set in the warm air zone away from the second fan assembly 300, for detecting the temperature on the warm air zone side of the heating component 400. At this time, the first preset temperature of the second detection component 540 should be larger; when the first ambient temperature on the warm air zone side is greater than or equal to the first preset temperature, it means that the temperature of the warm air flowing out of the warm air zone side is too high, and heating needs to be stopped to prevent the overheated warm air from scalding the user.
[0053] In addition, the second detection member 540 should be electrically connected to the main control board of the water heater, so that the main control board can receive and process the detection data from the second detection member 540, and then control the heating member 400 to perform the heating operation according to the detection data. When it is detected that the first ambient temperature around the heating member 400 is greater than or equal to the first preset temperature, the heating member 400 is controlled to stop heating; when it is detected that the first ambient temperature around the heating member 400 is less than the first preset temperature, the heating member 400 is controlled to continue or heat again.
[0054] like Figure 5 As shown, in a possible embodiment, the second connecting seat 530 includes a second connecting plate 531 and a second hollow plate 532 connected to the free end of the second connecting plate 531, and the end of the second connecting plate 531 away from the second hollow plate 532 is detachably connected to the shell 100, and the plane where the second hollow plate 532 is located is set at an angle to the plane where the second connecting plate 531 is located; the second detection element 540 is arranged on the second hollow plate 532, and the heating element 400 is connected to the shell 100 through the second connecting plate 531.
[0055] In this embodiment, the specific configuration of the second connection seat 530 is optimized. Specifically, the second connection seat 530 is configured as a composite component including at least a second connection plate 531 and a second hollow plate 532. The second connection plate 531 can be a bent long narrow plate, one end of which can be connected to the housing 100 by fasteners such as screws / bolts, and the other end is used to connect the second hollow plate 532; the side of one end of the second hollow plate 532 can be vertically connected to the side of the free end of the second connection plate 531. The inner angle for avoiding the heating element 400 is formed between the second hollow plate 532 and the second connection plate 531. In this way, the second detection member 540 arranged on the second hollow plate 532 can be distributed on the air outlet side or the air inlet side of the heating element 400, thereby improving the detection sensitivity and detection accuracy, and ensuring the safe operation of the air heating module 20. The other end side of the heating element 400 in the length direction Y of the shell 100 can be connected to the second connecting plate 531 to further enhance the connection tightness between the heating element 400 and the over-protection component 500.
[0056] In addition, the second hollow plate 532 is provided with hollow holes, which can not only reduce the overall weight of the second connecting seat 530 and realize the lightweight layout of the second connecting seat 530; but also reserve installation space for the second detection component 540, reduce the occupied volume of the over-protection component 500, and realize the compact and miniaturized layout of the over-protection component 500.
[0057] like Figure 1 and Figure 2 As shown, in a possible implementation, the second connection seat 530 and the first connection seat 510 are relatively arranged on the same side of the heating element 400 along the length direction Y of the housing 100. In this way, the first detection member 520 and the second detection member 540 can be arranged on the same side of the heating element 400 by utilizing the relative relationship between the second connection seat 530 and the first connection seat 510, at least saving the assembly space of the over-protection component 500 in the width direction X of the housing 100, reducing the space occupied by the air-heating module 20 in the width direction X of the housing 100, and reducing the occupied volume of the water heater.
[0058] like Figure 2 and Figure 5 As shown, in a possible implementation, the over-insurance component 500 also includes a third detection member 550 disposed on the second connecting seat 530, and the third detection member 550 is used to detect a second ambient temperature around the corresponding heating element 400, and the second ambient temperature is greater than the first ambient temperature.
[0059] In this embodiment, the specific configuration of the over-protection component 500 is further optimized. Specifically, the over-protection component 500 is configured as a combination component that at least includes a first connecting seat 510, a first detection member 520, a second connecting seat 530, a second detection member 540 and a third detection member 550. The third detection member 550 can be an over-temperature fuse, which can be electrically connected to the main control board of the water heater; the main control board receives and processes the detection data from the third detection member 550, and then controls the heating member 400 to stop the heating operation according to the detection data. For example, when it is detected that the second ambient temperature around the heating member 400 is greater than the second preset temperature, it means that the heating member 400 is in abnormal operation and is prone to safety accidents such as spontaneous combustion. At this time, it is necessary to control the heating member 400 to stop heating to cut off the warm air supply circuit, thereby further improving the operating safety of the air-heating module 20. This example is applicable to the case where the second detection member 540 fails.
[0060] like Figure 2 and Figure 5 As shown, in a possible implementation manner, the over-voltage protection component 500 further includes a fourth detection member 560 disposed on the second connection seat 530 , and the fourth detection member 560 is electrically connected to the heating member 400 for detecting the current flowing through the heating member 400 .
[0061] In this embodiment, the specific configuration of the over-protection component 500 is further optimized. Specifically, the over-protection component 500 is configured as a combination component including at least a first connection seat 510, a first detection member 520, a second connection seat 530, a second detection member 540 and a fourth detection member 560. The fourth detection member 560 can be an over-current fuse, which can be connected in series with the heating element 400 to the air-heating control circuit of the main control board; when the heating element 400 is short-circuited, the resistance of the air-heating control circuit becomes smaller, and the current becomes larger. When it exceeds the threshold of the over-current fuse, the over-current fuse disconnects the air-heating control circuit, and the air-heating module 20 stops operating, further improving the operating safety of the air-heating module 20. This example is applicable to the abnormal situation where the heating element 400 is short-circuited.

The upper cover 120 may be a plate-like structure that is approximately convex-shaped, and may be covered on the opening of the bottom shell 110 by snapping or the like to seal the installation cavity in the thickness direction Z of the shell 100; the first notch, the second notch and the air outlet notch may run through the entire shell 100 in the thickness direction Z to increase the air inlet and outlet area, increase the air inlet and outlet volume, and increase the warm air supply volume and air supply effect.
