Description

Technical Field

[0001] This disclosure relates to the field of household appliance technology, and in particular to a smart appliance. Background Technology

[0002] Gas water heaters provide instant hot water, which effectively meets residents' hot water needs. However, residential homes often experience problems such as low water pressure and fluctuating water flow. When one tap is using hot water and another tap is also using water, it can cause significant fluctuations in water flow at the first tap, and the water volume at each tap can be quite small, causing considerable inconvenience to users.

[0003] Currently, booster pumps are used to mitigate these water flow fluctuations. However, the water supply still needs to be replenished in real time from the tap water inlet, which may mean that the pump is diverting water from other households. Therefore, when the tap water pressure is low, the overall booster pump's pressure-boosting effect is not good. Utility Model Content

[0053] The disclosed smart appliance includes a controller, a gas water heater, and a water storage tank. By adding a water storage tank with a water storage function, when the tap water inlet pressure is low or the inlet water flow is small, it automatically and intelligently discharges the water stored in the storage tank into the inlet pipe, increasing the water flow in the inlet pipe. This provides the user with sufficient water flow for a certain period of time, ensuring a large and stable water flow from the gas water heater, thus improving the user experience. At the same time, the water stored in the storage tank is cold water (or room temperature water), which is cleaner and less prone to scale buildup. Furthermore, the storage tank is connected to the gas water heater's inlet pipe only through a single tank connection pipe, which serves as both the drain pipe and the water supply pipe for the storage tank, simplifying the structural layout of the smart appliance.

[0054] Figure 1 This is a structural diagram of an existing gas water heater.

[0055] Figure 2 This is a schematic diagram of the structure of a smart appliance provided in an embodiment of this disclosure;

[0056] Figure 3 This is a schematic diagram of the structure of a water storage tank in a smart appliance provided in an embodiment of this disclosure. Detailed Implementation

[0057] The present disclosure is further illustrated below by way of embodiments, but the present disclosure is not limited to the scope of the embodiments described herein.

[0058] The prefixes such as "first" and "second" used in this disclosure are merely for distinguishing different descriptive objects and do not limit the position, order, priority, quantity, or content of the described objects. The use of ordinal numbers and other prefixes used to distinguish descriptive objects in this disclosure does not constitute a limitation on the described objects. The description of the described objects is given in the claims or the context of the embodiments, and should not be construed as an unnecessary limitation. Furthermore, in the description of this embodiment, unless otherwise stated, "multiple" means two or more.

[0059] Figure 1 The diagram shows the structure of an existing gas water heater system. The gas water heater is connected to the tap water inlet pipe through the inlet pipe. After the water is heated by the gas heat exchange system, hot water is output through the outlet pipe. The hot water is then transported to each tap through the household hot water pipe. When one tap is using hot water and another tap is also using water, it will cause a large fluctuation in the water flow at the first tap, and the water flow at each tap will be relatively small, causing great inconvenience to users.

[0060] To address the aforementioned technical problems, this embodiment provides a smart appliance, such as... Figure 2 As shown, the smart appliance includes a controller 1, a gas water heater 2, and a water storage tank 3; the controller 1 is used to control the operation of the gas water heater.

[0061] The gas water heater 2 includes an inlet pipe 21, an outlet pipe 22, a first pressure sensor 23, and a water flow sensor 24;

[0062] The water storage tank 3 is connected to the water inlet pipe 21 via the water tank connection pipe 31, and a switch valve 32 is installed on the water tank connection pipe 31.

[0063] The first pressure sensor 23 and the water flow sensor 24 are both installed on the water inlet pipe 21 and are located downstream of the water pipe connection position between the water tank connecting pipe 31 and the water inlet pipe 21.

[0064] The first pressure sensor 23 is used to detect the current water pressure value in the water inlet pipe 21, and the water flow sensor 24 is used to detect the current water flow value in the water inlet pipe 21.

[0065] The controller 1 is also used to control the switch valve 32 to open when the current water pressure value is less than the first preset water pressure value and the current water flow value is less than the first preset water flow value, so that the water stored in the water storage tank 3 is discharged into the water inlet pipe 21.

[0066] The on / off valve is used to control the connection status between the water storage tank and the water inlet pipe.

[0067] In this embodiment, when a user has a water demand, the controller determines whether to activate the drainage function of the storage tank based on the current water flow rate (i.e., the current inlet water flow rate of the gas water heater) and the current water pressure (i.e., the current inlet water pressure of the gas water heater). Specifically, when the current water pressure is less than the first preset water pressure and the current water flow rate is less than the first preset water flow rate (i.e., the current water pressure and current water flow rate are both low), the controller opens the control valve to activate the drainage function of the storage tank. This automatically and intelligently drains the water stored in the storage tank into the inlet pipe, increasing the water flow rate in the inlet pipe and replenishing the inlet pipe. Even if multiple faucets are used simultaneously, sufficient water flow can be provided to the user within a certain period of time, ensuring a large and stable water flow rate from the gas water heater and improving the user experience.

[0068] Furthermore, the water tank stores cold water (or room temperature water), which is cleaner and less prone to scale buildup. At the same time, the water tank is connected to the gas water heater's inlet pipe only through a single water tank connection pipe, which serves as both the water tank's drain pipe and the water supply pipe, simplifying the structural layout of the smart appliance.

[0069] In an optional embodiment, the controller is further configured to control the switch valve to close when the current water flow value is greater than a second preset water flow value, so as to stop the water storage tank from draining into the water inlet pipe;

[0070] The second preset water flow rate value is greater than the first preset water flow rate value.

[0071] When a user has a water demand, the controller determines whether to turn off the drainage function of the storage tank based on the current water flow value. Specifically, when the current water flow value is greater than the second preset water flow value, that is, when the current water flow value is large, it is not necessary to consider whether the current water pressure value is large or small. As long as the current water flow value is large, it means that the water flow provided by the gas water heater to the user is sufficient, and there is no need to turn on the drainage function of the storage tank or to replenish the water inlet pipe. By controlling the switch valve to close, the storage tank stops draining water into the water inlet pipe.

[0072] In an optional embodiment, the controller is further configured to control the switch valve to close when the current water pressure value is greater than the second preset water pressure value and the current water flow value is less than the first preset water flow value, so as to stop the water storage tank from draining into the water inlet pipe;

[0073] The second preset water pressure value is greater than the first preset water pressure value.

[0074] When a user has a water demand, the controller determines whether to turn off the water tank's drainage function based on the current water flow rate and water pressure. Specifically, if the current water pressure is greater than the second preset water pressure value and the current water flow rate is less than the first preset water flow rate value, that is, the current water pressure is high and the current water flow rate is low, it indicates that the user's water demand is already low, meaning the faucet opening is low. In this case, there is no need to turn on the water tank's drainage function and there is no need to replenish the inlet pipe. By controlling the valve to close, the water tank stops draining water into the inlet pipe.

[0075] In an alternative implementation, such as Figure 2 As shown, the water storage tank 3 is equipped with a diaphragm 33 inside, and the water storage tank 3 includes a water level detection module 34;

[0076] The diaphragm 33 is used to isolate the water and air in the water storage tank 3;

[0077] The water level detection module 34 is used to detect the current water level value in the water storage tank 3 and send the current water level value to the controller 1;

[0078] The controller is used to open the switch valve 32 when the current water level is lower than the preset water level and the current water flow is zero, so that the water in the inlet pipe 21 flows into the water storage tank 3 through the water tank connection pipe 31.

[0079] When the current water level is lower than the preset water level and the current water flow is zero (i.e., the user has no water demand), the controller opens the valve, allowing water from the inlet pipe to flow into the storage tank via the tank connection pipe, thus automatically replenishing the storage tank. If the controller detects a user demand during the replenishment process, it exits the replenishment mode.

[0080] In an alternative implementation, such as Figure 2 As shown, the water storage tank includes an air pump 35;

[0081] The exhaust end of the air pump 35 is connected to the water storage tank 3, and the air inlet end of the air pump 35 is connected to the outside air; the air pump 35 is used to push the diaphragm 33 to move downward along the inner wall of the water storage tank 3.

[0082] Controller 1 is used to control the inflation speed of the air pump in order to control the drainage speed of the water storage tank 3.

[0083] Specifically, the air pump is located on top of the water storage tank.

[0084] When the water tank's drainage function is activated, the tank is inflated by an air pump. The air pump pushes the diaphragm downwards along the inner wall of the tank, allowing water to flow into the gas water heater's inlet pipe, thus maintaining stable water pressure and flow rate.

[0085] Specifically, the gas water heater uses a water pressure sensor to detect the current water pressure in the inlet pipe in real time, and a water flow sensor to detect the current water flow in the inlet pipe in real time. The controller controls the gas pump's charging speed based on the current water pressure and water flow, thereby controlling the drainage speed of the storage tank and stabilizing the inlet water pressure and flow of the gas water heater.

[0086] In an alternative implementation, such as Figure 2 As shown, the water storage tank includes an air pump 35;

[0087] The exhaust end of the air pump 35 is connected to the water storage tank 3, and the air inlet end of the air pump 35 is connected to the outside air.

[0088] The air pump 35 is used to pull the diaphragm 33 upward along the inner wall of the water storage tank 3;

[0089] The controller 1 is used to control the exhaust speed of the air pump 35 in order to control the water replenishment speed of the water storage tank 3.

[0090] When water needs to be added to the storage tank, the air pump can vent the water tank and pull the diaphragm upward along the inner wall of the storage tank, thereby speeding up the water replenishment process.

[0091] Specifically, the gas water heater will detect the current water pressure value of the inlet pipe in real time through a water pressure sensor and the current water flow value of the inlet pipe in real time through a water flow sensor. The controller will control the gas pump's charging speed based on the current water pressure value and the current water flow value, thereby controlling the water replenishment speed of the storage tank.

[0092] In an alternative implementation, such as Figure 3 As shown, the water level detection module 34 includes a first Hall sensor 341, a second Hall sensor 342, a partition 343, and a partition magnet 344;

[0093] The partition 343 and the partition magnet 344 are located inside the water storage tank 3, and the partition magnet is located on the partition;

[0094] The partition 343 abuts against the inner wall of the water storage tank 3;

[0095] The partition 343 abuts against the diaphragm 33, and the partition 343 moves up and down along the inner wall of the water storage tank 3 following the diaphragm 33.

[0096] The first Hall sensor 341 and the second Hall sensor 342 are located on the outer wall of the water storage tank 3;

[0097] The first Hall sensor 341 is located near the top of the water tank 3 and is used to detect the highest water level value of the water tank 3.

[0098] The second Hall sensor 342 is located near the bottom of the water tank and is used to detect the lowest water level in the tank.

[0099] Specifically, the partition and the diaphragm are connected by rivets, and there are partition magnets on the edge of the partition.

[0100] When the water level in the tank is low, the diaphragm contracts, and the partition is at its lower limit position (i.e., the lowest water level). The position of the partition magnet is aligned with the second Hall sensor, which can detect that the current water level is the lowest water level.

[0101] When the water tank is full, the diaphragm expands and the partition is at its upper limit position (maximum water level). The position of the partition magnet is aligned with the first Hall sensor, which can detect that the current water level is the maximum water level.

[0102] In one alternative implementation, the water level detection module is a pressure sensor, which can determine the current water level value by measuring the water pressure.

[0103] In an alternative implementation, such as Figure 2 As shown, a one-way valve 25 is installed on the water inlet pipe 21;

[0104] One-way valve 25 is located upstream of the water pipe connection.

[0105] A check valve can prevent water from flowing back into a gas water heater.

[0106] In an optional embodiment, the water tank 3 includes a pressure relief port 36, a drain valve 37, and a second pressure sensor 38;

[0107] The second pressure sensor 38 is used to detect the current air pressure value in the water storage tank 3 and send the current air pressure value to the controller 1;

[0108] The controller 1 is used to open the drain valve 37 when the current air pressure value is greater than the preset air pressure value, so that the water in the water storage tank 3 can be discharged from the pressure relief port 36.

[0109] When the current air pressure is greater than the preset air pressure, i.e. when the current air pressure is too high, in order to ensure safety, it is necessary to open the drain valve and discharge the water in the water tank from the pressure relief port to protect the water tank.

[0110] In one alternative embodiment, the gas water heater 2 includes an inlet water temperature sensor 26 and an outlet water temperature sensor 27;

[0111] The inlet water temperature sensor 26 is installed on the inlet water pipe 21 to detect the current inlet water temperature value in the inlet water pipe 21;

[0112] The outlet water temperature sensor 27 is installed on the outlet water pipe 22 to detect the current outlet water temperature value in the outlet water pipe 22.

[0113] The gas water heater uses an inlet water temperature sensor to detect the current inlet water temperature in the inlet pipe and an outlet water temperature sensor to detect the current outlet water temperature in the outlet pipe. This allows the controller to adjust the operation of the gas water heater based on the current inlet and outlet water temperatures to meet the user's hot water temperature requirements.

[0114] In one alternative embodiment, the gas water heater 2 includes an intake proportional valve 28, a gas heat exchange system 29, an intake pipe 30, and an exhaust pipe 31;

[0115] The intake proportional valve 28 is installed on the intake pipe 30;

[0116] The controller 1 is used to adjust the opening of the intake proportional valve 28 to regulate the amount of gas supplied to the gas heat exchange system 29 via the intake pipeline 30.

[0117] The exhaust pipe 31 is used to discharge the waste gas produced after the gas is burned by the gas heat exchange system 29.

[0118] In one alternative embodiment, the smart appliance further includes a display module;

[0119] The display module is used to display the current water level in the water storage tank.

[0120] The display module shows the current water level in the water tank, allowing users to know the water level in the tank in a timely manner.

[0121] In one alternative implementation, the smart appliance further includes a human-computer interaction module;

[0122] The human-computer interaction module is used to receive user commands and send them to the controller;

[0123] The controller controls smart appliances to perform corresponding operations based on user commands.

[0124] User commands include voice commands and / or key press commands.

[0125] Smart appliances can be controlled by voice. The human-computer interaction module can include a voice receiving module and a voice parsing module. The voice receiving module receives the user's voice commands, and the voice parsing module parses the commands. Based on the parsed commands, the controller controls the corresponding devices to perform corresponding operations, thereby realizing the intelligent control of smart appliances and improving the user experience.

[0126] For example, users can actively wake up the water tank to drain or replenish water using voice commands.

[0127] The human-computer interaction module may also include a button module, which receives button commands from the user. The controller then controls the corresponding devices to perform the corresponding operations, thereby realizing the intelligent control of smart appliances and improving the user experience.

[0128] For example, the user can press or touch the drain button to activate the water tank for draining, or press or touch the water replenishment button to activate the water tank for replenishment.

Those skilled in the art can make various changes or modifications to these embodiments without departing from the principles and essence of this disclosure, but all such changes and modifications fall within the scope of protection of this disclosure.
