Description

Technical Field

[0001] This invention relates to the field of smart homes, and more specifically, to a water heater, a control method and control device for the water heater, and a readable storage medium. Background Technology

[0002] If a user falls or loses consciousness in the bathroom during their daily bathing process, and their family members are not around or cannot discover it in time, it can easily cause secondary injury to the elderly. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art.

[0004] Therefore, the first aspect of the present invention provides a water heater.

[0005] A second aspect of the present invention provides a method for controlling a water heater.

[0006] A third aspect of the present invention provides a control device for a water heater.

[0007] The fourth aspect of the present invention provides a water heater.

[0008] The fifth aspect of the present invention provides a readable storage medium.

[0009] The first aspect of the present invention provides a water heater, comprising: a body; and a radar detection device disposed on the body, the radar detection device being capable of acquiring radar data.

[0010] The water heater proposed in this invention includes a body and a radar detection device. The radar detection device is mounted on the body and is capable of acquiring radar data. Specifically, the position of the radar detection device on the body can be set according to actual conditions, ensuring that the detection end of the radar detection device is not shielded by the body, and guaranteeing that the radar detection device can acquire radar data within the bathing area.

[0011] Specifically, this invention incorporates a radar detection device on the water heater's body, and the detection signal of this device is not blocked by the body. Thus, during user operation, the radar detection device can acquire radar data related to the user within the bathing area, enabling the water heater to operate based on this data and enhancing its intelligence. Furthermore, acquiring user-related data via radar ensures reliable data acquisition and eliminates any concerns about user privacy.

[0012] For example, during a user's shower, the radar detection device can acquire radar data associated with the user and determine the user's condition based on the acquired radar data. If it determines that the user has fallen, it can take corresponding measures; for example, controlling the electronic device connected to the water heater to issue an alarm, or controlling the server connected to the water heater to dial the user's pre-set identification card number to simultaneously associate with the user, thereby ensuring that the showerer receives timely medical attention.

[0013] In some possible designs, the radar detection device is located in one of the following positions on the fuselage: top, bottom, middle, or side.

[0014] In this design, the placement of the radar detection device on the unit is relatively flexible, including but not limited to the top, bottom, middle, and sides of the unit. The key is to ensure that the radar signal of the detection device is not blocked by the unit. Specifically, during user operation, the device can be positioned according to the actual layout of the bathroom and the shape of the unit.

[0015] In some possible designs, the radar detection device is located on the outer surface of the fuselage.

[0016] In this design, the radar detection device can be located on the outer surface of the fuselage. That is, the present invention can directly place the radar detection device on the outer surface of the fuselage; in this way, on the one hand, it can ensure that the radar signal of the radar detection device is not blocked by the fuselage and reduce the requirements for the fuselage material, so that the fuselage can be made of metal or non-metal materials; on the other hand, it facilitates the assembly and subsequent maintenance of the radar detection device. During the maintenance process, the staff can more intuitively observe the radar detection device and can also easily disassemble the radar detection device.

[0017] In some possible designs, the fuselage includes a shielded enclosure; the radar detection device is located inside the fuselage, and the shielded enclosure covers the radar detection device.

[0018] In this design, the fuselage includes a shielding shell, which is a non-metallic shell. Furthermore, the radar detection device is located inside the fuselage, and the shielding shell covers it. This serves two purposes: firstly, the shielding shell ensures the radar signal transmission of the radar detection device, thereby guaranteeing that the device can acquire radar data relevant to the user; secondly, the shielding shell protects the radar detection device, reducing the risk of damage from external forces.

[0019] In some possible designs, the fuselage includes a display panel; the radar detection device is located on the display panel.

[0020] In this design, the unit includes a display panel. The display panel features an interface that shows parameters such as water temperature and remaining water level. Furthermore, during daily use, the display panel is oriented towards the shower area, allowing the user to clearly see the interface. Further, this invention incorporates a radar detection device on the display panel, also oriented towards the shower area. This ensures that the radar detection device is focused on the user during use, enabling timely and comprehensive acquisition of radar data relevant to the user, thus facilitating subsequent intelligent control of the water heater.

[0021] In some possible designs, the display panel is tilted relative to the horizontal plane, and the detection end of the radar detection device is tilted downwards relative to the horizontal plane.

[0022] In this design, the water heater is installed at a relatively high position during daily use. Therefore, this invention tilts the display panel, making it angled relative to the horizontal plane, so that the display interface faces the user for easier viewing. Furthermore, a radar detection device is mounted on the display panel and tilted downwards relative to the horizontal plane, ensuring that the bathing area is within the radar detection device's detection area as much as possible, thereby ensuring that the radar detection device comprehensively acquires radar data related to the user.

[0023] In some possible designs, the angle between the detection direction of the radar detection device and the horizontal plane is greater than 0° and less than or equal to 45°.

[0024] In this design, the detection direction of the radar detection device forms a certain angle with the horizontal plane, which is greater than 0° and less than or equal to 45°. Specifically, this invention optimizes the tilt of the radar detection device's detection direction relative to the horizontal plane. While ensuring the radar detection device's detection direction is tilted, the angle between the radar detection device's detection direction and the horizontal plane is designed to be less than or equal to 45°. This ensures that the user's bathing area is within the radar detection device's detection range, thereby ensuring that the radar detection device can acquire radar data associated with the user.

[0025] In particular, if the angle between the detection direction of the radar detection device and the horizontal plane is greater than 45°, the detection area of ​​the radar detection device will be relatively high, which will prevent the radar detection device from acquiring radar data at positions close to the ground.

[0026] In some possible designs, the end of the radar detection device is equipped with a hinge structure, through which the radar detection device is rotatably connected to the fuselage.

[0027] In this design, the end of the radar detection device is equipped with a hinge structure. This hinge allows the radar detection device to be rotatably connected to the fuselage, enabling adjustment of its detection direction. Therefore, in actual use, the user can rotate the radar detection device according to actual needs, oriented it towards the user, and ensuring that the radar detection device can acquire radar data relevant to the user.

[0028] For example, adults and children have different heights. Therefore, during use, users can adjust the orientation of the radar detection device according to their own height to ensure that the radar detection device is suitable for users of different heights.

[0029] For example, different users have different bathroom environments, and the installation locations of their water heaters also vary. Therefore, during use, users can adjust the orientation of the radar detection device according to their own specific circumstances, ensuring that the radar detection device is suitable for users of different heights.

[0030] In some possible designs, multiple mounting positions are provided on the fuselage; the radar detection device can be installed in any of these positions.

[0031] In this design, multiple mounting positions are provided on the fuselage. The invention allows the radar detection device to be installed in any of these positions. Furthermore, the remaining positions can be used as alternatives, allowing the radar detection device to be installed in a suitable position when the user needs to adjust its installation location.

[0032] Specifically, the radar detection device can be installed in a designated location before the water heater leaves the factory, allowing the user to adjust it themselves if needed; alternatively, the user can install the radar detection device to ensure its location better suits their needs.

[0033] In some possible designs, the water heater also includes: a controller electrically connected to the radar detection device; and a water flow regulating device electrically connected to the controller, which can control the operation of the water flow regulating device based on the radar data acquired by the radar detection device.

[0034] In this design, the water heater also includes a controller and a water flow regulating device. The water flow regulating device is installed on the water circuit system of the water heater and can regulate the water flow rate. In addition, the controller is electrically connected to the radar detection device and the water flow regulating device, and can control the operation of the water flow regulating device based on the radar data detected by the radar detection device, so as to realize intelligent control of the water heater.

[0035] For example, during a user's shower, after the radar detection device detects radar data associated with the user, the controller analyzes the detected radar data and determines if the user has fallen. In this case, the controller will control the water flow regulating device to reduce the water flow from the water heater or directly stop the water flow. This reduces water waste and prevents continuous water flow from affecting the user's safety.

[0036] In some possible designs, the water heater may also include: a controller, located inside the unit; and a communication device electrically connected to the controller, which can control the communication device to operate based on radar data acquired by the radar detection device.

[0037] In this design, the water heater also includes a controller and a communication device. The communication device is connected to electronic equipment; furthermore, the controller is electrically connected to both the radar detection device and the communication device, and can control the communication device based on radar data detected by the radar detection device to achieve automatic alarm functionality for the water heater.

[0038] For example, during a user's shower, after the radar detection device detects radar data associated with the user, the controller analyzes the detected radar data and determines when the user is in a fall. The controller then controls the communication device to send a corresponding signal to the electronic device, thereby enabling timely calls to the user in the event of a fall and providing timely medical assistance.

[0039] A second aspect of the present invention provides a control method for a water heater, used in the water heater of the first aspect of the present invention, wherein the water heater is communicatively connected to an electronic device, and the control method includes: acquiring radar data associated with a user; determining the user's state based on the radar data; acquiring user input when the user's state is a preset state; and controlling the communication device of the water heater to operate based on the acquisition result of the input.

[0040] The water heater control method proposed in this invention can be used in the water heater of the first aspect of this invention. The water heater is connected to an electronic device via a communication device, and a radar detection device is installed on the body of the water heater; the detection signal of the radar detection device is not blocked by the body.

[0041] Furthermore, when a user is using the water heater, this invention acquires radar data associated with the user through a radar detection device, analyzes the detected radar data, and then determines the user's state. Further, if the user is determined to be in a preset state, this invention acquires the user's input and controls the communication device based on that input. Thus, when the user is in a preset state, this invention can control the communication device based on the user's input, allowing the communication device to operate according to the user's actual situation and reducing the probability of false triggering of the communication device.

[0042] In other words, when the user is in a preset state, the present invention can further acquire the user's input and control the communication device to work based on the acquisition of the user's input. Compared with related technologies, this invention adds a user confirmation process and only controls the communication device to send relevant signals to the electronic device when the user needs medical treatment, thereby reducing the probability of false triggering of the communication device.

[0043] For example, during use, a user might fall but not seriously, in which case no medical attention or notification of other family members is necessary. In this case, the present invention can control the communication device to not issue corresponding instructions based on the user's input. However, if the user falls and the situation is more serious, requiring medical attention or notification of other family members, the present invention can control the communication device to issue corresponding instructions based on the user's input, thereby ensuring the user receives timely medical attention.

[0044] In some possible designs, the inputs include a first type of input and a second type of input. Based on the acquisition result of the input, the communication device of the water heater is controlled to operate, including: when the first type of input is acquired, controlling the communication device to send an alarm signal to the electronic device so that the electronic device performs a preset operation in response to the alarm signal; and / or when neither the first type of input nor the second type of input is acquired within a preset time period, controlling the communication device to send an alarm signal to the electronic device so that the electronic device performs a preset operation in response to the alarm signal; and / or when the second type of input is acquired, controlling the communication device to remain in standby mode.

[0045] In this design, the input includes a first type of input and a second type of input; the first type of input is a definite input, and the second type of input is a negative input. This invention, when determining whether the user is in a fall-like state, further determines the nature of the user's input.

[0046] Specifically, in cases where a user falls and the situation is serious, the user needs appropriate medical attention or needs to notify other family members. In this situation, the user can input a first-type command after the fall to indicate the need for medical attention. Correspondingly, after determining that the user is in a preset state and receiving the user's first-type input, the present invention determines that the user needs medical attention. At this time, the present invention controls the communication device to send an alarm signal to the electronic device, thereby causing the electronic device to perform a preset operation in response to the received alarm information.

[0047] Specifically, in the event of a user's fall and a serious situation, the user needs appropriate medical treatment or needs to notify other family members. However, at this time, the user may be unconscious and unable to issue the aforementioned first type of input. Therefore, when the present invention determines that the user is in a preset state and receives any input from the user, the present invention controls the communication device to send an alarm signal to the electronic device, thereby causing the electronic device to perform a preset operation in response to the received alarm information.

[0048] Specifically, in cases where a user falls but the injury is not serious, the user does not require medical attention or to notify other family members. In this situation, the user can input a second type of command after the fall to indicate the need for medical assistance. Correspondingly, after determining that the user is in a preset state and receiving the user's second type of input, the present invention determines that the user does not require medical assistance. At this point, the present invention will control the communication device to remain in standby mode.

[0049] In some possible designs, the electronic device includes a server that calls a preset user identification card number in response to an alarm signal.

[0050] In this design, the electronic device includes a server that stores preset user identification card numbers associated with users. Specifically, in the event of a user falling and requiring medical attention, or in the event of a need to notify other family members, the invention controls the communication device to send an alarm message to the server. Correspondingly, in response to the received alarm message, the server directly calls the preset user identification card number, thereby informing the user of the user's condition and enabling timely assistance.

[0051] Specifically, the user with the preset user identification card number can be a family member or a medical worker, etc.

[0052] In some possible designs, the electronic device includes an alarm device that outputs alarm information in response to an alarm signal.

[0053] In this design, the electronic device includes an alarm device capable of issuing alarm information. Specifically, in cases where a user falls and requires medical attention, or when other family members need to be notified, the invention controls the communication device to send alarm information to the alarm device. Correspondingly, in response to the received alarm information, the alarm device directly outputs action information, thereby informing other members in the vicinity of the alarm device of the user's situation and enabling timely rescue.

[0054] Specifically, alarm devices can be electronic devices such as mobile phones and tablets, or related alarm devices such as buzzers.

[0055] In some possible designs, the input includes at least one of the following: voice input, gesture input, touch input, and button input.

[0056] In this design, input methods include, but are not limited to: voice input, gesture input, touch input, and button input.

[0057] Specifically, when input includes voice input, a user can determine whether an alarm is needed upon falling using voice commands. For example, the first type of input could be "Need to call an alarm," and the second type could be "Do not need to call an alarm." If a user believes they need medical attention after a fall, they can directly say "Need to call an alarm," causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can directly say "Do not need to call an alarm," and the communication device will remain in standby mode. Furthermore, if a user falls but does not utter either of the above statements, it indicates that the user may be unconscious, in which case the communication device will directly send an alarm message to the electronic device.

[0058] Specifically, when input includes gesture input, a user can determine whether an alarm is needed by making a gesture when falling. For example, the first type of input could be an "OK" gesture, and the second type of input could be an "X" gesture. If a user believes they need medical attention after falling, they can directly make an "OK" gesture, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can make an "X" gesture, and the communication device will remain in standby mode. Furthermore, if a user falls but does not make any of the above gestures, it indicates that the user may be unconscious, in which case the communication device will directly send an alarm message to the electronic device.

[0059] Specifically, when input includes touch input, a user can determine whether an alarm is needed by touching the radar detection device when falling. For example, the first type of input can be touching the radar detection device once, and the second type of input can be touching the radar detection device twice. If a user believes they need medical attention after a fall, they can touch the radar detection device once, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can touch the radar detection device twice, and the communication device will remain in standby mode. Furthermore, if a user falls but does not touch the radar detection device, it indicates that the user may be unconscious; in this case, the communication device will directly send an alarm message to the electronic device.

[0060] Specifically, when input includes button input, a user can determine whether an alarm is needed by pressing a button when falling. For example, the first type of input could be pressing the radar detection device once, and the second type of input could be pressing the radar detection device twice. If a user believes they need medical attention after a fall, they can press the radar detection device once, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can press the radar detection device twice, and the communication device will remain in standby mode. Furthermore, if a user falls but does not press the radar detection device, it indicates that the user may be unconscious; in this case, the communication device will directly send an alarm message to the electronic device.

[0061] In some possible designs, the preset state includes a fall state, and the user's state is determined based on radar data, including: determining the user's current height based on radar data; and determining the user's state as a fall state if the user's current height is less than or equal to a height threshold.

[0062] In this design, the preset state includes a fall state. Furthermore, in determining the user's state, this invention can determine the user's current height based on radar data and compare it with a height threshold; if the user's current height is less than or equal to the height threshold, it indicates that the user is currently in a fall state.

[0063] Understandably, during use, a user's height when falling is significantly lower than their standing height, and the user is close to the ground when falling. Therefore, this invention compares the user's current height with a height threshold to determine the user's current state, and thus determines whether the user is in a falling state.

[0064] In some possible designs, before determining the user's status based on radar data, the following steps are also included: determining the user's identity information based on radar data; and determining the height threshold corresponding to the identity information.

[0065] In this design, different users have different heights; for example, adults are taller than children. Therefore, for different users, this invention determines the user's identity information based on radar data, and then determines the corresponding height threshold based on the user's identity information.

[0066] For example, if the user is determined to be a child, the present invention uses a first height threshold as the judgment criterion; if the user is determined to be an adult, the present invention uses a second height threshold as the judgment criterion; wherein the first height threshold is less than the second height threshold.

[0067] Specifically, this invention identifies user body part features based on radar data, and then identifies the user's identity through these body part features. These body parts include, but are not limited to, the torso, legs, arms, and head.

[0068] Specifically, the present invention determines the user's gait based on the movement speed and acceleration of various parts of the user's body, and then identifies the user's identity information based on the user's gait.

[0069] A third aspect of the present invention provides a control device for a water heater, used in the water heater of the first aspect of the present invention, wherein the water heater is communicatively connected to an electronic device, and the control device includes: an acquisition unit for acquiring radar data associated with a user; a determination unit for determining the user's state based on the radar data; the acquisition unit is further configured to acquire user input when the user's state is a preset state; and a control unit for controlling the operation of the water heater's communication device based on the acquisition result of the input.

[0070] The control device for the water heater proposed in this invention can be used in the water heater of the first aspect of this invention. The water heater is communicatively connected to an electronic device via a communication device, and a radar detection device is installed on the body of the water heater, the detection signal of which is not blocked by the body.

[0071] Furthermore, the water heater's control device includes an acquisition unit, a determination unit, and a control unit. When a user is using the water heater, the acquisition unit acquires radar data associated with the user via a radar detection device. The determination unit analyzes the detected radar data to determine the user's status. Further, if the user is determined to be in a preset state, the acquisition unit acquires the user's input and controls the communication device based on that input. Thus, when the user is in a preset state, the control unit can control the communication device based on the user's input, ensuring the communication device operates according to the user's actual situation and reducing the probability of false triggering.

[0072] In other words, when the user is in a preset state, the present invention can further acquire the user's input and control the communication device to work based on the acquisition of the user's input. Compared with related technologies, this invention adds a user confirmation process and only controls the communication device to send relevant signals to the electronic device when the user needs medical treatment, thereby reducing the probability of false triggering of the communication device.

[0073] For example, during use, a user might fall but not seriously, in which case no medical attention or notification of other family members is necessary. In this case, the present invention can control the communication device to not issue corresponding instructions based on the user's input. However, if the user falls and the situation is more serious, requiring medical attention or notification of other family members, the present invention can control the communication device to issue corresponding instructions based on the user's input, thereby ensuring the user receives timely medical attention.

[0074] In some possible designs, the inputs include a first type of input and a second type of input. Based on the acquisition result of the input, the communication device of the water heater is controlled to operate. Specifically, the control unit is used to control the communication device to send an alarm signal to the electronic device when the first type of input is acquired, so that the electronic device can perform a preset operation in response to the alarm signal; and / or the control unit is used to control the communication device to send an alarm signal to the electronic device if neither the first type of input nor the second type of input is acquired within a preset time period, so that the electronic device can perform a preset operation in response to the alarm signal; and / or the control unit is used to control the communication device to remain in standby mode when the second type of input is acquired.

[0075] In some possible designs, the electronic device includes a server that calls a preset user identification card number in response to an alarm signal.

[0076] In some possible designs, the electronic device includes an alarm device that outputs alarm information in response to an alarm signal.

[0077] In some possible designs, the input includes at least one of the following: voice input, gesture input, touch input, and button input.

[0078] In some possible designs, the determining unit is also used to determine the user's identity information based on radar data; and to determine the height threshold corresponding to the identity information.

[0079] The fourth aspect of the present invention provides a water heater, including a processor, a memory, and a program or instructions stored in the memory and executable on the processor, wherein when the program or instructions are executed by the processor, the steps of the control method for the water heater as described in the second aspect of the present invention are implemented.

[0080] The water heater proposed in this invention has all the beneficial effects of the water heater control method of the second aspect of this invention, which will not be discussed in detail here.

[0081] The fifth aspect of the present invention provides a readable storage medium having a program stored thereon, which, when executed by a processor, implements the steps of the control method for a water heater as described in the second aspect of the present invention.

[0082] The readable storage medium proposed in this invention has all the beneficial effects of the water heater control method of the second aspect of this invention, which will not be discussed further here.

[0094] 102 Fuselage, 104 Radar detection device, 106 Shielding shell, 108 Display panel. Detailed Implementation

[0095] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0096] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0097] The following reference Figures 1 to 8 This describes a water heater, a water heater control method and control device, and a readable storage medium provided according to some embodiments of the present invention.

[0098] like Figures 1 to 4 As shown, the first embodiment of the present invention proposes a water heater, including a body and a radar detection device.

[0099] Among them, such as Figures 1 to 4 As shown, the radar detection device 104 is mounted on the fuselage 102 and is capable of acquiring radar data. Specifically, the position of the radar detection device 104 on the fuselage 102 can be set according to the actual situation, ensuring that the detection end of the radar detection device 104 is not shielded by the fuselage 102, and ensuring that the radar detection device 104 can acquire radar data in the bathing area.

[0100] Specifically, such as Figures 1 to 4 As shown, the present invention includes a radar detection device 104 mounted on the water heater body 102, and the detection signal of the radar detection device 104 is not blocked by the body 102. Thus, during user operation, the radar detection device 104 can acquire radar data related to the user within the bathing area, enabling the water heater to operate based on the acquired radar data, thereby improving the water heater's intelligence. Furthermore, acquiring user-related data via radar ensures reliable data acquisition and avoids any issues related to user privacy.

[0101] For example, during a user's bathing process, the radar detection device 104 can acquire radar data associated with the user and determine the user's status based on the acquired radar data. If it is determined that the user has fallen, response measures can be taken; for example, controlling the electronic device connected to the water heater to issue an alarm, or controlling the server connected to the water heater to dial the pre-set user identification card number to simultaneously associate with the user, thereby ensuring that the bather receives timely medical attention.

[0102] In this embodiment, further, as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the radar detection device 104 can be positioned relatively flexibly on the fuselage 102, including but not limited to the top, bottom, middle, and sides of the fuselage 102. This is as long as the radar signal of the radar detection device 104 is not blocked by the fuselage 102.

[0103] Specifically, during user operation, the settings can be adjusted according to the actual layout of the bathroom and the shape of the unit 102.

[0104] The second embodiment of the present invention proposes a water heater, which, based on the first embodiment, further includes:

[0105] like Figures 1 to 4 As shown, the radar detection device 104 can be located on the outer surface of the fuselage 102. That is, the present invention can directly mount the radar detection device 104 on the outer surface of the fuselage 102.

[0106] In this way, on the one hand, it can ensure that the radar signal of the radar detection device 104 is not blocked by the fuselage 102, and reduce the requirements for the material of the fuselage 102, so that the fuselage 102 can be made of metal or non-metal materials; on the other hand, it facilitates the assembly of the radar detection device 104 and subsequent maintenance. During the maintenance process, the staff can observe the radar detection device 104 more intuitively and can also easily disassemble the radar detection device 104.

[0107] The third embodiment of the present invention proposes a water heater, which, based on the first embodiment, further includes:

[0108] like Figures 1 to 4 As shown, the fuselage 102 includes a shielding shell 106. The shielding shell 106 is a non-metallic shell. In addition, the radar detection device 104 is located inside the fuselage 102, and the shielding shell 106 covers the radar detection device 104.

[0109] In this way, on the one hand, the radar signal transmission of the radar detection device 104 can be guaranteed by the shielding shell 106, thereby ensuring that the radar detection device 104 can obtain radar data associated with the user; on the other hand, the radar detection device 104 can be shielded by the shielding shell 106, thereby providing a certain degree of protection for the radar detection device 104 and reducing the risk of damage to the radar detection device 104 due to external forces.

[0110] The fourth embodiment of the present invention proposes a water heater, which, based on the first embodiment, further includes:

[0111] like Figure 1 As shown, the main body 102 includes a display panel 108. The display panel 108 has a display interface that shows parameters such as water temperature and remaining water level. Furthermore, during daily use of the water heater, the display panel 108 is oriented towards the bathing area so that the user can clearly see the display interface.

[0112] Furthermore, such as Figure 1 As shown, the present invention places the radar detection device 104 on the display panel 108, and positions the radar detection device 104 towards the bathing area. In this way, during the user's use of the water heater, the radar detection device 104 is positioned towards the user and can acquire radar data associated with the user in a timely and comprehensive manner, thereby facilitating subsequent intelligent control of the water heater.

[0113] In this embodiment, the water heater is installed at a relatively high position during daily use. Therefore, the present invention tilts the display panel 108 so that it is tilted relative to the horizontal plane, thereby making the display interface of the display panel 108 face the user for easy observation.

[0114] Furthermore, such as Figure 1 As shown, the radar detection device 104 is mounted on the display panel 108 and is tilted downward relative to the horizontal plane, so that the bathing area is as close as possible to the detection area of ​​the radar detection device 104, thereby ensuring that the radar detection device 104 can fully acquire radar data related to the user.

[0115] In this embodiment, the detection direction of the radar detection device 104 forms a certain angle with the horizontal plane, which is greater than 0° and less than or equal to 45°. Specifically, the present invention optimizes the tilt of the detection direction of the radar detection device 104 relative to the horizontal plane. While ensuring the tilt setting of the detection direction of the radar detection device 104, the angle between the detection direction of the radar detection device 104 and the horizontal plane is designed to be less than or equal to 45°.

[0116] This ensures that the user's bathing area is within the detection area of ​​the radar detection device 104, thereby ensuring that the radar detection device 104 can acquire radar data associated with the user.

[0117] In particular, if the angle between the detection direction of the radar detection device 104 and the horizontal plane is greater than 45°, the detection area of ​​the radar detection device 104 will be relatively high, which will cause the radar detection device 104 to be unable to obtain radar data at positions close to the ground.

[0118] Based on any of the above embodiments, a hinge structure (not shown in the figure) is further provided at the end of the radar detection device 104. This allows the radar detection device 104 to be rotatably connected to the fuselage 102 via the hinge structure, enabling adjustment of the detection direction of the radar detection device 104. Therefore, in actual use, the user can rotate the radar detection device 104 according to actual needs, thereby making the radar detection device 104 face the user and ensuring that the radar detection device 104 can acquire radar data associated with the user.

[0119] For example, adults and children have different heights. Therefore, during use, users can adjust the orientation of the radar detection device 104 according to their own height, ensuring that the radar detection device 104 is suitable for users of different heights.

[0120] For example, different users have different bathroom environments, and the installation locations of their water heaters also differ. Therefore, during use, users can adjust the orientation of the radar detection device 104 according to their own actual situation, ensuring that the radar detection device 104 is suitable for users of different heights.

[0121] Based on any of the above embodiments, the fuselage 102 is further provided with multiple mounting positions. The present invention allows the radar detection device 104 to be mounted in any of these positions. Furthermore, the remaining positions can be used as alternative positions, allowing the radar detection device 104 to be mounted in a suitable position when the user needs to adjust its mounting position.

[0122] Specifically, the radar detection device 104 can be installed in a specific location before the water heater leaves the factory, and the user can adjust it themselves if needed; alternatively, the user can install the radar detection device 104 to ensure that the installation location of the radar detection device 104 better suits the user's actual situation.

[0123] Based on any of the above embodiments, the water heater further includes a controller (not shown in the figure) and a water flow regulating device (not shown in the figure). The water flow regulating device is installed on the water circuit system of the water heater and is capable of regulating the water flow rate of the water heater. Furthermore, the controller is electrically connected to the radar detection device 104 and the water flow regulating device, and is capable of controlling the operation of the water flow regulating device based on the radar data detected by the radar detection device 104, thereby achieving intelligent control of the water heater.

[0124] For example, during a user's shower, after the radar detection device 104 detects radar data associated with the user, the controller analyzes the detected radar data and determines that the user is in a fall-prone state. In this case, the controller will control the water flow regulating device to reduce the water flow from the water heater or directly stop the water flow. This reduces water waste and prevents continuous water flow from affecting the user's safety.

[0125] Based on any of the above embodiments, the water heater further includes a controller and a communication device (not shown in the figure). The communication device is communicatively connected to an electronic device; furthermore, the controller is electrically connected to the radar detection device 104 and the communication device, and can control the operation of the communication device based on the radar data detected by the radar detection device 104 to achieve automatic alarm of the water heater.

[0126] For example, during a user's shower, after the radar detection device 104 detects radar data associated with the user, the controller analyzes the detected radar data and determines when the user is in a fall. The controller then controls the communication device to send a corresponding signal to the electronic device, thereby enabling timely calls to the user in the event of a fall and providing timely medical assistance.

[0127] Based on any of the above embodiments, in the water heater proposed in this invention, the radar detection device 104 is a millimeter-wave radar detection device 104.

[0128] The fifth embodiment of the present invention proposes a control method for a water heater, which can be used in the water heater of the first aspect of the present invention. The water heater is communicatively connected to an electronic device via a communication device, and a radar detection device is installed on the body of the water heater, the detection signal of which is not blocked by the body.

[0129] Furthermore, such as Figure 5 As shown, the control methods for water heaters include:

[0130] Step 502: Obtain radar data associated with the user;

[0131] Step 504: Determine the user's status based on radar data;

[0132] Step 506: If the user's state is a preset state, obtain the user's input;

[0133] Step 508: Based on the input acquisition results, control the communication device of the water heater to work.

[0134] The water heater control method proposed in this invention can be used in the water heater of the first aspect of this invention. The water heater is connected to an electronic device via a communication device, and a radar detection device is installed on the body of the water heater; the detection signal of the radar detection device is not blocked by the body.

[0135] Furthermore, when a user is using the water heater, this invention acquires radar data associated with the user through a radar detection device, analyzes the detected radar data, and then determines the user's state. Further, if the user is determined to be in a preset state, this invention acquires the user's input and controls the communication device based on that input. Thus, when the user is in a preset state, this invention can control the communication device based on the user's input, allowing the communication device to operate according to the user's actual situation and reducing the probability of false triggering of the communication device.

[0136] In other words, when the user is in a preset state, the present invention can further acquire the user's input and control the communication device to work based on the acquisition of the user's input. Compared with related technologies, this invention adds a user confirmation process and only controls the communication device to send relevant signals to the electronic device when the user needs medical treatment, thereby reducing the probability of false triggering of the communication device.

[0137] For example, during use, a user might fall but not seriously, in which case no medical attention or notification of other family members is necessary. In this case, the present invention can control the communication device to not issue corresponding instructions based on the user's input. However, if the user falls and the situation is more serious, requiring medical attention or notification of other family members, the present invention can control the communication device to issue corresponding instructions based on the user's input, thereby ensuring the user receives timely medical attention.

[0138] The sixth embodiment of the present invention proposes a control method for a water heater, which further improves upon the fifth embodiment by:

[0139] The input includes a first type of input and a second type of input; the first type of input is a definite input, and the second type of input is a negative input. In determining whether the user is in a fall-like state, this invention further determines the extent of the user's input acquisition.

[0140] Specifically, in cases where a user falls and the situation is serious, the user needs appropriate medical attention or needs to notify other family members. In this situation, the user can input a first-type command after the fall to indicate the need for medical attention. Correspondingly, after determining that the user is in a preset state and receiving the user's first-type input, the present invention determines that the user needs medical attention. At this time, the present invention controls the communication device to send an alarm signal to the electronic device, thereby causing the electronic device to perform a preset operation in response to the received alarm information.

[0141] Specifically, in the event of a user's fall and a serious situation, the user needs appropriate medical treatment or needs to notify other family members. However, at this time, the user may be unconscious and unable to issue the aforementioned first type of input. Therefore, when the present invention determines that the user is in a preset state and receives any input from the user, the present invention controls the communication device to send an alarm signal to the electronic device, thereby causing the electronic device to perform a preset operation in response to the received alarm information.

[0142] Specifically, in cases where a user falls but the injury is not serious, the user does not require medical attention or to notify other family members. In this situation, the user can input a second type of command after the fall to indicate the need for medical assistance. Correspondingly, after determining that the user is in a preset state and receiving the user's second type of input, the present invention determines that the user does not require medical assistance. At this point, the present invention will control the communication device to remain in standby mode.

[0143] The seventh embodiment of the present invention proposes a control method for a water heater, which further improves upon the sixth embodiment by:

[0144] The electronic device may include a server storing a preset user identification card number associated with a user. In the event of a user falling and requiring medical attention, or in the need to notify other family members, the present invention controls the communication device to send an alarm message to the server. Correspondingly, in response to the received alarm message, the server directly calls the preset user identification card number, thereby informing the user of the user's condition and enabling timely rescue.

[0145] Specifically, the user with the preset user identification card number can be a family member or a medical worker, etc.

[0146] Electronic devices may include alarm devices, which are capable of issuing alarm information. Specifically, in cases where a user falls and requires medical attention or to notify other family members, the present invention controls the communication device to send alarm information to the alarm device. Correspondingly, in response to the received alarm information, the alarm device directly outputs relevant information, thereby informing other members in the vicinity of the alarm device of the user's situation and enabling timely rescue.

[0147] Specifically, alarm devices can be electronic devices such as mobile phones and tablets, or related alarm devices such as buzzers.

[0148] The eighth embodiment of the present invention proposes a control method for a water heater, which further improves upon the sixth and seventh embodiments by:

[0149] Input methods include, but are not limited to: voice input, gesture input, touch input, and button input.

[0150] Specifically, when input includes voice input, a user can determine whether an alarm is needed upon falling using voice commands. For example, the first type of input could be "Need to call an alarm," and the second type could be "Do not need to call an alarm." If a user believes they need medical attention after a fall, they can directly say "Need to call an alarm," causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can directly say "Do not need to call an alarm," and the communication device will remain in standby mode. Furthermore, if a user falls but does not utter either of the above statements, it indicates that the user may be unconscious, in which case the communication device will directly send an alarm message to the electronic device.

[0151] Specifically, when input includes gesture input, a user can determine whether an alarm is needed by making a gesture when falling. For example, the first type of input could be an "OK" gesture, and the second type of input could be an "X" gesture. If a user believes they need medical attention after falling, they can directly make an "OK" gesture, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can make an "X" gesture, and the communication device will remain in standby mode. Furthermore, if a user falls but does not make any of the above gestures, it indicates that the user may be unconscious, in which case the communication device will directly send an alarm message to the electronic device.

[0152] Specifically, when input includes touch input, a user can determine whether an alarm is needed by touching the radar detection device when falling. For example, the first type of input can be touching the radar detection device once, and the second type of input can be touching the radar detection device twice. If a user believes they need medical attention after a fall, they can touch the radar detection device once, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can touch the radar detection device twice, and the communication device will remain in standby mode. Furthermore, if a user falls but does not touch the radar detection device, it indicates that the user may be unconscious; in this case, the communication device will directly send an alarm message to the electronic device.

[0153] Specifically, when input includes button input, a user can determine whether an alarm is needed by pressing a button when falling. For example, the first type of input could be pressing the radar detection device once, and the second type of input could be pressing the radar detection device twice. If a user believes they need medical attention after a fall, they can press the radar detection device once, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can press the radar detection device twice, and the communication device will remain in standby mode. Furthermore, if a user falls but does not press the radar detection device, it indicates that the user may be unconscious; in this case, the communication device will directly send an alarm message to the electronic device.

[0154] The ninth embodiment of the present invention proposes a control method for a water heater, which, based on the fifth, sixth, seventh, and eighth embodiments, further includes:

[0155] The preset states include a fall state. Furthermore, in determining the user's state, this invention can determine the user's current height based on radar data and compare it with a height threshold; if the user's current height is less than or equal to the height threshold, it indicates that the user is currently in a fall state.

[0156] Understandably, during use, a user's height when falling is significantly lower than their standing height, and the user is close to the ground when falling. Therefore, this invention compares the user's current height with a height threshold to determine the user's current state, and thus determines whether the user is in a falling state.

[0157] In this embodiment, the heights of different users are different; for example, adults are taller than children. Therefore, for different users, the present invention determines the user's identity information based on radar data, and then determines the corresponding height threshold based on the user's identity information.

[0158] For example, if the user is determined to be a child, the present invention uses a first height threshold as the judgment criterion; if the user is determined to be an adult, the present invention uses a second height threshold as the judgment criterion; wherein the first height threshold is less than the second height threshold.

[0159] Specifically, this invention identifies user body part features based on radar data, and then identifies the user's identity through these body part features. These body parts include, but are not limited to, the torso, legs, arms, and head.

[0160] Specifically, the present invention determines the user's gait based on the movement speed and acceleration of various parts of the user's body, and then identifies the user's identity information based on the user's gait.

[0161] like Figure 6 As shown, the tenth embodiment of the present invention provides a control device 600 for a water heater, which can be used in any of the water heaters described in the above embodiments. The water heater is communicatively connected to an electronic device via a communication device, and a radar detection device is installed on the body of the water heater, the detection signal of which is not blocked by the body.

[0162] Furthermore, the control device 600 of the water heater includes an acquisition unit 602, a determination unit 604, and a control unit 606. When a user is using the water heater, the acquisition unit 602 acquires radar data associated with the user through a radar detection device. The determination unit 604 analyzes the detected radar data to determine the user's state. Further, if the user is determined to be in a preset state, the acquisition unit 602 acquires the user's input and controls the communication device based on the user's input. Thus, when the user is in a preset state, the control unit 606 can control the communication device based on the user's input, ensuring the communication device operates according to the user's actual situation and reducing the probability of false triggering.

[0163] In other words, when the user is in a preset state, the present invention can further acquire the user's input and control the communication device to work based on the acquisition of the user's input. Compared with related technologies, this invention adds a user confirmation process and only controls the communication device to send relevant signals to the electronic device when the user needs medical treatment, thereby reducing the probability of false triggering of the communication device.

[0164] For example, during use, a user might fall but not seriously, in which case no medical attention or notification of other family members is necessary. In this case, the present invention can control the communication device to not issue corresponding instructions based on the user's input. However, if the user falls and the situation is more serious, requiring medical attention or notification of other family members, the present invention can control the communication device to issue corresponding instructions based on the user's input, thereby ensuring the user receives timely medical attention.

[0165] The eleventh embodiment of the present invention provides a control device 600 for a water heater, which, based on the tenth embodiment, further includes:

[0166] The input includes a first type of input and a second type of input; the first type of input is a definite input, and the second type of input is a negative input. The determining unit 604, upon determining that the user is in a fall state, will further determine the extent of the user's input acquisition.

[0167] Specifically, in the event of a user's fall and a relatively serious situation, the user needs appropriate medical treatment or needs to notify other family members. In this case, the user can input a first-type command after the fall to indicate the need for medical treatment. Correspondingly, after determining that the user is in a preset state and the acquisition unit 602 further acquires the user's first-type input, the determining unit 604 determines that the user needs medical treatment. At this time, the control unit 606 controls the communication device to send an alarm signal to the electronic device, thereby causing the electronic device to perform a preset operation in response to the received alarm information.

[0168] Specifically, in the event of a user's fall and a serious condition, the user needs appropriate medical treatment or needs to notify other family members. However, the user may be unconscious and unable to issue the aforementioned first type of input. Therefore, when the determining unit 604 determines that the user is in a preset state and the acquiring unit 602 further acquires any input from the user, the control unit 606 will control the communication device to send an alarm signal to the electronic device, thereby causing the electronic device to perform a preset operation in response to the received alarm information.

[0169] Specifically, in cases where a user falls but the injury is not serious, the user does not require medical attention or to notify other family members. In this situation, the user can input a second type of command after the fall to indicate the need for medical assistance. Correspondingly, after determining that the user is in a preset state and the acquisition unit 602 further acquires the user's second type of input, the determining unit 604 determines that the user does not require medical assistance. At this point, the control unit 606 will keep the communication device in standby mode.

[0170] The twelfth embodiment of the present invention provides a control device 600 for a water heater, which, based on the eleventh embodiment, further includes:

[0171] The electronic device may include a server that stores a preset user identification card number associated with a user. In the event of a user falling and requiring medical attention or to notify other family members, the control unit 606 controls the communication device to send an alarm message to the server. Correspondingly, in response to the received alarm message, the server directly calls the preset user identification card number, thereby informing the user of the user's condition and enabling timely assistance.

[0172] Specifically, the user with the preset user identification card number can be a family member or a medical worker, etc.

[0173] Electronic devices may include alarm devices, which are capable of issuing alarm information. Specifically, in cases where a user falls and requires medical attention or to notify other family members, the control unit 606 controls the communication device to send alarm information to the alarm device. Correspondingly, in response to the received alarm information, the alarm device directly outputs relevant information, thereby informing other members in the vicinity of the alarm device of the user's situation and enabling timely rescue.

[0174] Specifically, alarm devices can be electronic devices such as mobile phones and tablets, or related alarm devices such as buzzers.

[0175] The thirteenth embodiment of the present invention provides a control device 600 for a water heater, which, based on the eleventh and twelfth embodiments, further includes:

[0176] Input methods include, but are not limited to: voice input, gesture input, touch input, and button input.

[0177] Specifically, when input includes voice input, a user can determine whether an alarm is needed upon falling using voice commands. For example, the first type of input could be "Need to call an alarm," and the second type could be "Do not need to call an alarm." If a user believes they need medical attention after a fall, they can directly say "Need to call an alarm," causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can directly say "Do not need to call an alarm," and the communication device will remain in standby mode. Furthermore, if a user falls but does not utter either of the above statements, it indicates that the user may be unconscious, in which case the communication device will directly send an alarm message to the electronic device.

[0178] Specifically, when input includes gesture input, a user can determine whether an alarm is needed by making a gesture when falling. For example, the first type of input could be an "OK" gesture, and the second type of input could be an "X" gesture. If a user believes they need medical attention after falling, they can directly make an "OK" gesture, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can make an "X" gesture, and the communication device will remain in standby mode. Furthermore, if a user falls but does not make any of the above gestures, it indicates that the user may be unconscious, in which case the communication device will directly send an alarm message to the electronic device.

[0179] Specifically, when input includes touch input, a user can determine whether an alarm is needed by touching the radar detection device when falling. For example, the first type of input can be touching the radar detection device once, and the second type of input can be touching the radar detection device twice. If a user believes they need medical attention after a fall, they can touch the radar detection device once, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can touch the radar detection device twice, and the communication device will remain in standby mode. Furthermore, if a user falls but does not touch the radar detection device, it indicates that the user may be unconscious; in this case, the communication device will directly send an alarm message to the electronic device.

[0180] Specifically, when input includes button input, a user can determine whether an alarm is needed by pressing a button when falling. For example, the first type of input could be pressing the radar detection device once, and the second type of input could be pressing the radar detection device twice. If a user believes they need medical attention after a fall, they can press the radar detection device once, causing the communication device to send an alarm message to the electronic device. Conversely, if the user does not need to remain still, they can press the radar detection device twice, and the communication device will remain in standby mode. Furthermore, if a user falls but does not press the radar detection device, it indicates that the user may be unconscious; in this case, the communication device will directly send an alarm message to the electronic device.

[0181] The fourteenth embodiment of the present invention provides a control device 600 for a water heater, which, based on the tenth, eleventh, twelfth, and thirteenth embodiments, further includes:

[0182] The preset states include a fall state. Furthermore, in determining the user's state, the determining unit 604 can determine the user's current height based on radar data and compare it with a height threshold; if the user's current height is less than or equal to the height threshold, it indicates that the user is currently in a fall state.

[0183] Understandably, during use, a user's height when falling is significantly lower than their standing height, and the user is close to the ground when falling. Therefore, this invention compares the user's current height with a height threshold to determine the user's current state, and thus determines whether the user is in a falling state.

[0184] In this embodiment, the heights of different users are further differentiated; for example, adults are taller than children. Therefore, for different users, the determining unit 604 will determine the user's identity information based on radar data, and then determine the corresponding height threshold based on the user's identity information.

[0185] For example, if the user is determined to be a child, the present invention uses a first height threshold as the judgment criterion; if the user is determined to be an adult, the present invention uses a second height threshold as the judgment criterion; wherein the first height threshold is less than the second height threshold.

[0186] Specifically, the determining unit 604 identifies the user's body part characteristics based on radar data, and then identifies the user's identity through these body part characteristics. These body parts include, but are not limited to, the torso, legs, arms, and head.

[0187] Specifically, the determining unit 604 determines the user's gait based on the movement speed and acceleration of various parts of the user's body, and then identifies the user's identity information based on the user's gait.

[0188] like Figure 7 As shown, the fifteenth embodiment of the present invention proposes a water heater 700, including a memory 704 and a processor 702.

[0189] The memory 704 stores a program or instructions that can be executed by the processor 702. Furthermore, when the program or instructions are executed by the processor 702, they can implement the steps of the water heater control method as described in any of the above embodiments. Therefore, this water heater possesses all the beneficial effects of the water heater control method of any of the above embodiments, which will not be elaborated upon here.

[0190] The sixteenth embodiment of the present invention proposes a readable storage medium on which a program is stored.

[0191] When the program is executed by a processor, it can implement the steps of the water heater control method as described in any of the above embodiments. Therefore, the readable storage medium has all the beneficial effects of the water heater control method of any of the above embodiments, which will not be elaborated here.

[0192] The seventeenth embodiment of this invention proposes a control method for a water heater, such as... Figure 8 As shown, the control methods for water heaters include:

[0193] Step 802, water heater starts;

[0194] Step 804: The radar detection device detects the signal;

[0195] Step 806: Determine if the user has fallen. If the result is yes, proceed to step 808; otherwise, return to step 804.

[0196] Step 808: Determine whether the voice confirmation alarm is triggered. If the result is yes, proceed to step 810; otherwise, return to step 804.

[0197] Step 810: The communication device sends an alarm signal to the electronic device;

[0198] Step 812: The electronic device performs a preset operation.

[0199] The water heater control method proposed in this invention addresses the issue of secondary injuries to elderly users who fall or lose consciousness in the bathroom when family members are not present or cannot detect the fall in time. The method utilizes a radar detection device to monitor the user's posture. When a fall occurs, an alarm signal is transmitted to the water heater's control board. Upon receiving the alarm signal, the control board confirms the fall via voice. If the user confirms or does not respond, the control board directly transmits the alarm signal to a server. The server automatically dials a preset user identification card number, allowing family members to quickly obtain information and ensure timely medical attention for the elderly. Simultaneously, an alarm can be triggered via a mobile app, for example, by synchronizing the alarm information.
