Description

Technical Field

[0001] This utility model relates to the technical field of wall-hung boiler thermostats, specifically to a thermostat with remote control function. Background Technology

[0002] Traditional thermostats typically consist of a receiver and a remote control. In use, the receiver is connected to the boiler's main board via a wire, and then controls the boiler to turn the heating function on or off based on the detected room temperature and the set temperature. Therefore, the receiver needs to be installed near the boiler, and due to transmission distance limitations, the distance between the remote control and the receiver cannot be too long, otherwise remote control will not be effective. This wired control method makes the installation of traditional thermostats very complex and easily restricted by the installation location, making them inconvenient to use.

[0003] With the popularization of smart homes, users' demand for remote control of thermostats is increasing. Traditional thermostats can no longer meet users' needs.

Detailed Implementation

[0027] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0028] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0030] refer to Figure 1-7 The present invention provides a temperature controller with remote control function, including a housing 1, and a power supply component and a control component 2 disposed in the housing 1, wherein the power supply component is used to supply power to the control component 2;

[0031] The control component 2 includes a circuit board 20, a wireless communication module 21, a microprocessor (such as an MCU chip), and a temperature sensing element 22, which are disposed on the circuit board 20 and electrically connected to each other. The circuit board 20 is fixed inside the housing 1. The power supply component is electrically connected to the circuit board 20 and is used to supply power to the circuit board 20.

[0032] The wireless communication module 21 is used to communicate with the wall-hung boiler. Specifically, the wall-hung boiler is also equipped with a built-in WiFi module. When the thermostat and the wall-hung boiler are on the same local area network, the wireless communication module 21 of the thermostat can connect with the built-in WiFi module of the wall-hung boiler. The signal output terminal of the temperature sensing element 22 is connected to the signal input terminal of the microprocessor. The microprocessor is configured to send heating or heating stop commands to the wall-hung boiler through the wireless communication module 21.

[0033] Its specific working principle is as follows: When the thermostat provided by this utility model is in use, the temperature sensing element 22 detects the indoor ambient temperature in real time and transmits the signal to the microprocessor. The microprocessor can compare the room temperature detected by the temperature sensing element 22 with the user's preset temperature value. When the room temperature is lower than the preset temperature value, the microprocessor sends a heating command to the wall-hung boiler through the wireless communication module 21. After receiving the heating command, the built-in WiFi module in the wall-hung boiler controls the wall-hung boiler to perform the heating action. When the room temperature is higher than the preset temperature value, the microprocessor sends a stop heating command to the wall-hung boiler through the wireless communication module 21. After receiving the stop heating command, the built-in WiFi module in the wall-hung boiler controls the wall-hung boiler to perform the action of turning off the heating. Furthermore, the thermostat can also upload control commands to the cloud server via the wireless communication module 21, and the cloud server forwards the commands to the built-in WiFi module of the wall-hung boiler, and then executes the relevant command actions. At the same time, the cloud server can connect to the user's terminal device (such as mobile phone, computer, tablet, etc.), allowing the user to directly set the preset temperature value and view relevant information on the terminal device, realizing the effect of remote control. It is convenient to use, without the need for complicated connection cables to connect the thermostat and the wall-hung boiler. The installation of the thermostat is not limited by location, which further improves the user experience.

[0034] This utility model provides two implementation methods for power supply to the power supply component:

[0035] refer to Figure 4-6 In the first embodiment, the wireless communication module 21 is a WiFi module (or a Bluetooth module). By placing the wall-mounted boiler and the thermostat in the same local area network, the WiFi module of the thermostat and the built-in WiFi module of the wall-mounted boiler are connected. At the same time, the WiFi module of the thermostat is connected to the cloud server through a router to realize remote control of the terminal device. The temperature sensing element 22 is a temperature sensing probe. The temperature sensing probe can directly contact the external ambient air to detect the temperature in real time. The power supply component includes a power supply interface 30 (e.g., Type-C / Micro-USB). The temperature sensing probe and the WiFi module are located on the top of the circuit board 20, and the power supply interface 30 is located on the bottom of the circuit board 20. Separate placement can avoid excessive heat concentration. The outer casing 1 has a charging hole (not shown) corresponding to the position of the power supply interface 30. One end of the power supply interface 30 is electrically connected to the circuit board 20, and the other end can be plugged into an external power source through the charging hole. When powered, the external power cord is directly inserted into the power supply interface 30, and then the circuit is directly guided to the circuit board 20 for power supply. Therefore, in the first embodiment, the user needs to keep the thermostat plugged in (connected to an external power source) in order to use it. This method can reduce costs to some extent, eliminates the need to monitor the thermostat's power status, and is simpler and more direct.

[0036] In the second embodiment, the power supply component includes a battery (e.g., a lithium battery, not shown) and a power supply interface 30. The battery is electrically connected to the power supply interface 30, and an external power source can charge the battery through the power supply interface 30. The battery is also electrically connected to the circuit board 20. In this embodiment, by building a battery inside the thermostat, energy storage can be achieved. During operation, when an external power source is connected to the power supply interface 30 to charge the battery, it also supplies power to the circuit board 20. In the event of a power outage, the battery can continue to supply power to the circuit board 20, ensuring the continuous operation of the thermostat.

[0037] refer to Figure 2-4In a preferred embodiment, a flexible protective plug 101 (mainly a silicone or rubber plug) is provided on the outer shell 1 near the charging port. One end of the flexible protective plug 101 is fixed to the outer shell 1. In this embodiment, the fixed end of the flexible protective plug 101 to the outer shell 1 means that it is hinged to the outer shell 1. The other end can be flipped relative to the outer shell 1. When the flexible protective plug 101 is flipped, the charging port can be closed or opened to hide or expose the power supply interface 30, thereby playing the role of dust prevention and protection of the power supply interface 30. In other embodiments, the flexible protective plug 101 can also be independently detachable relative to the outer shell 1. That is, when not charging, the charging port can be blocked with the flexible protective plug 101, and when charging is needed, the flexible protective plug 101 can be pulled out of the charging port.

[0038] refer to Figure 7 In a preferred embodiment, the wireless communication module 21 (WiFi module / Bluetooth module), the temperature sensing element 22 (temperature probe), and the microprocessor (MCU chip) are all disposed on the same side of the circuit board 20. The other side of the circuit board 20 is provided with a display screen 23, which is electrically connected to the circuit board 20. The microprocessor is also electrically connected to the display screen 23. The display screen 23 is an LCD display screen 23 used to display temperature information. For example, after a user sets the preset temperature and mode via a terminal device (mobile phone, tablet, etc.), the relevant setting information is transmitted to the thermostat's WiFi module via a cloud server. The microprocessor compares the preset temperature value with the current room temperature, then issues a heating or stopping command, returns the information to the WiFi module, and simultaneously displays it on the LCD screen 23 (meaning the user can visually observe the temperature changes through the screen 23). When the boiler malfunctions, the fault code information is transmitted to the cloud server via the boiler's built-in WiFi module. The cloud server then transmits the information to the thermostat's WiFi module and the terminal device. The microprocessor then transmits the fault information received from the WiFi module to the LCD screen 23 for display, allowing the user to promptly detect the fault. Furthermore, a display window 103 is provided on the outer casing 1, and the shape of the display window 103 is adapted to the shape of the display screen 23. That is, the size, shape, and position of the display window 103 correspond to the display screen 23.

[0039] refer to Figure 6 and 7 In a preferred embodiment, the circuit board 20 is further provided with control buttons 24, which are spaced below the display screen 23. The control buttons 24 are connected to the microprocessor and can be used to set a preset temperature value. That is, in addition to setting the preset temperature value through the terminal device, the mode and temperature value can also be set through the control buttons 24 on the thermostat and displayed on the display screen 23.

[0040] refer to Figure 1-4 In a preferred embodiment, the outer casing 1 includes an upper casing 10 and a lower casing 11, with the upper casing 10 and the lower casing 11 connected to form a cavity for accommodating the power supply component and the control component 2; the upper casing 10 and the lower casing 11 are detachably connected, specifically by bolt fixing, such as... Figure 3 and 4 As shown, one of the upper shell 10 or the lower shell 11 has four through mounting holes 110 distributed around its perimeter, and the other has positioning posts 104 corresponding to the four mounting holes 110. The positioning posts 104 have internal threads. During installation, the mounting holes 110 are aligned with the positioning posts 104, and then bolts are driven in, allowing the bolts to engage with the internal threads of the positioning posts 104, thus fixing the upper shell 10 and the lower shell 11. For disassembly, simply unscrewing the bolts separates the upper shell 10 and the lower shell 11. Of course, other methods besides those in this embodiment can also be used to achieve the detachability of the upper shell 10 and the lower shell 11. The detachability of the upper shell 10 and the lower shell 11 facilitates maintenance or replacement of components (such as the circuit board 20 or the battery). Furthermore, the outer shell 1 is made of plastic, resulting in lower cost.

[0041] refer to Figure 2 and 3 In a preferred embodiment, the outer casing 1 further includes a back plate 12, which is magnetically connected to the lower casing 11. An adhesive element 120 (e.g., 3M adhesive) is provided on the side of the back plate 12 facing away from the lower casing 11. Specifically, a first magnetic part 111 is provided on the lower casing 11, while a second magnetic part (not shown) is provided on the back plate 12. The first magnetic part 111 and the second magnetic part have opposite magnetic properties. Utilizing the principle of magnetic adsorption, quick assembly and disassembly of the lower casing 11 and the back plate 12 are achieved. The adhesive element 120 on the side of the back plate 12 facing away from the lower casing 11 allows the back plate 12 to be magnetically attached to the lower casing 11 during installation. The thermostat can then be directly adhered to a wall or tabletop using the adhesive element 120 on the back plate 12, making it lighter and easier to install, eliminating the need for drilling and wiring required in traditional thermostats.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this application.
