Description

A whole-house environment zoned intelligent control system Technical Field

[0001] This utility model relates to the field of smart homes, specifically to a whole-house environment zoned intelligent control system. Background Technology

[0002] Smart home technology uses the home as a platform to connect various devices within the home through the Internet of Things (IoT) to create an intelligent living environment. It integrates home-related facilities using comprehensive wiring, network communication, security, automatic control, and audio-visual technologies to build an efficient management system for residential facilities and daily household affairs, thereby enhancing home security, convenience, comfort, and aesthetics.

[0003] With the advent of fresh air systems, indoor and outdoor air exchange has been achieved, effectively ensuring indoor air quality. Furthermore, combined with smart home control, these systems can adjust the fresh air flow based on different indoor environmental parameters. However, shortcomings also exist: current technologies typically install sensors in the return air duct of the fresh air system to monitor the environment, and then control the fresh air flow based on the sensor data. This means the return air duct is affected by the environment of each room, making it impossible to accurately monitor and control every single room. This results in insufficient control precision; for example, insufficient fresh air flow to crowded rooms, while large-volume exchange occurs in sparsely populated or unoccupied rooms, leading to waste. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a whole-house environment zoned intelligent control system.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A whole-house environmental zoning intelligent control system includes a fresh air handling unit and a control system for controlling the operation of the fresh air handling unit.

[0021] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. Components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0022] In the description of this invention, terms such as "upper," "lower," "left," "right," "front," and "rear," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0023] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. Example 1

[0024] Referring to Figures 1 and 2, this embodiment provides a whole-house environmental zoning intelligent control system, including a fresh air handling unit 20 and a control system for controlling the operation of the fresh air handling unit 20. The fresh air duct and return air duct of the fresh air handling unit 20 are respectively connected to multiple rooms 1 inside and outside the house to form air exchange. In this specific embodiment, the fresh air handling unit 20 includes a fresh air fan 21, a first air distribution box 22, and a second air distribution box 23. The first air distribution box 22 has a one-inlet-multiple-outlet structure. The inlet of the first air distribution box 22 is connected to the fresh air outlet of the fresh air fan 21, and the multiple outlets of the first air distribution box 22 are respectively connected to multiple rooms 1 through pipes 15 to form fresh air inlets 24. The second air distribution box 23 has a one-outlet-multiple-inlet structure. The outlet of the second air distribution box 23 is connected to the old air inlet of the fresh air fan 21, and the multiple inlets of the second air distribution box 23 are respectively connected to multiple rooms 1 through pipes 15 to form return air inlets 24. The fresh air inlet and old air outlet of the fresh air fan 21 are connected to the outside. When the fresh air unit 21 starts, fresh air from outside flows sequentially through the fresh air inlet, fresh air outlet, and the inlet of the first air distribution box 22, and then through multiple outlets of the first air distribution box 22 to distribute it to each room 1. Meanwhile, the stale air in each room 1 flows back to the second air distribution box 23 through the return air vent 25 and gathers there. Finally, it flows out of the room sequentially through the outlet of the second air distribution box 23, the stale air inlet of the fresh air unit 21, and the stale air outlet. That is, the passage containing the fresh air inlet, fresh air outlet, the inlet of the first air distribution box 22, the multiple outlets of the first air distribution box 22, and the fresh air vent 24 in room 1 is the fresh air passage; the passage containing the return air vent, the inlet of the second air distribution box 23, the outlet of the second air distribution box 23, the stale air inlet of the fresh air unit 21, and the stale air outlet is the return air passage.

[0025] In this embodiment, the fresh air duct and / or return air duct of the fresh air unit 20 are equipped with air regulating valves 30 on the branch ducts connecting each room; as in this specific embodiment, the air regulating valves 30 are electric air valves, and the air regulating valves 30 are set at multiple outlets of the first air distribution box 22 and multiple inlets of the second air distribution box 23; of course, they can also be set only at multiple outlets of the first air distribution box 22 or only at multiple inlets of the second air distribution box 23.

[0026] The control system includes a main control panel 11 and multiple partition control panels 12, each communicatively connected to the main control panel 11. The partition control panels 12 are located in multiple rooms 1, with one partition control panel 12 for each room 1. Each partition control panel 12 integrates a sensor 14 for detecting the indoor environment; that is, wiring with the sensor 14 is added to the existing partition control panel 12. Each partition control panel 12 is connected to an air regulating valve 30 on a branch channel connecting to its respective room 1 and to the sensor 14 integrated within the partition control panel 12. The signal output terminal of the sensor 14 is connected to the input terminal of the partition control panel 12, and the control terminal of the partition control panel 12 is connected to the corresponding air regulating valve 30, enabling the partition control panel 12 to receive the sensing information from the sensor 14 and control the air regulating valve 30 based on this information.

[0027] In this embodiment, sensor 14 is a carbon dioxide concentration sensor used to monitor the carbon dioxide concentration in room 1 and transmit it to the zone control panel 12. The zone control panel 12 compares the monitored concentration value with a preset value to control the opening and closing degree of the air regulating valve 30 to control the airflow. For example, when the carbon dioxide concentration is in the range of 600-700 PPM, the zone control panel 12 controls the opening ratio of the air regulating valve 30 to 20% (i.e., 20% of the maximum flow rate); when the carbon dioxide concentration is in the range of 700-800 PPM, the zone control panel 12 controls the opening ratio of the air regulating valve 30 to 40%, and so on. Each zone control panel 12 can be preset according to actual conditions, thereby achieving precise control, automatic adjustment of the fresh air unit's airflow, and control of energy consumption. Of course, in other embodiments, the parameters determining the airflow of the fresh air unit 21 are not limited to the carbon dioxide concentration value. They can also be determined by one or more combinations of temperature, humidity, PM2.5 concentration, and VOC (volatile organic compound) concentration. For example, a certain amount of airflow can be controlled when one parameter reaches a preset value, or a certain amount of airflow can be controlled when multiple parameters reach preset values ​​simultaneously. These can all be preset according to actual needs. Simultaneously, the sensor 14 can be modified to detect corresponding parameters, such as adding a temperature sensor, humidity sensor, PM2.5 concentration sensor, and VOC sensor, etc. Furthermore, the parameters of temperature, humidity, PM2.5 concentration, and VOC concentration can also be used as control references for other devices, as described in Embodiment Two.

[0028] Meanwhile, the main control panel 11 and multiple zone control panels 12 can communicate with each other and transmit commands to control corresponding devices. For example, the main control panel 11 controls the connected fresh air unit 21. The fresh air unit 21 can be controlled directly by the main control panel 11, or it can be controlled by sending commands from the zone control panels 12 to the main control panel 11. Similarly, commands can be sent from the main control panel 11 to one of the zone control panels 12 to control the devices in a specific room 1, such as controlling the airflow in that room 1.

[0029] Specifically, the structure, data communication method, data processing, and control method of the main control panel 11 and the partition control panel 12 are all existing technologies and will not be described in detail here.

[0030] Furthermore, in this embodiment, the fresh air unit 21 includes a fresh air circulation section connecting the fresh air outlet and the fresh air inlet, and an old air circulation section connecting the old air outlet and the old air inlet. The fresh air circulation section and the old air circulation section are connected to a heat exchanger to achieve heat exchange between the fresh and old air. In this embodiment, the fresh air circulation section and the old air circulation section are arranged alternately, and a heat exchanger is connected at the intersection. This allows the temperature of the incoming air to be closer to the room temperature, which is beneficial for maintaining the temperature.

[0031] More specifically, it also includes an auxiliary heater 40, which is installed outdoors and connected to the fresh air intake of the fresh air unit 21. The main control panel 11 is connected to the auxiliary heater 40 (i.e., the control terminal of the main control panel 11 is connected to the auxiliary heater 40) to control the operation of the auxiliary heater 40. The auxiliary heater 40 is suitable for use in cold environments. Of course, in other embodiments, the structure of the auxiliary heater 40 may not be used.

[0032] At least one room 1 is equipped with a fragrance device 13. In this embodiment, each room 1 is equipped with a fragrance device 13. The partition control panel 12 is also connected to the fragrance device 13 in its respective room 1, allowing the user to control the fragrance device 13 in their room 1. For example, the partition control panel 12 can control the start and stop of the fan motor and the opening and closing of the fragrance channel of the fragrance device 13, thus enabling individual control for different needs and creating different partitioned atmospheres. Specifically, the fragrance device 13 adopts an existing structure, which will not be described in detail here.

[0033] Specifically, the fragrance device 13 is installed at the fresh air inlet 24 of the room 1, and the fragrance it outputs can be quickly diffused by the airflow flowing in through the fresh air inlet 24.

[0034] Of course, in other embodiments, the structure of the fragrance device 13 may not be used.

[0035] Furthermore, the main control screen 11 also has a communication connection to a remote terminal, such as a mobile phone via Bluetooth, allowing remote control by inputting commands through the mobile phone. Specifically, this technology is existing technology, and the specific implementation method will not be detailed further. Example 2

[0036] The whole-house environment zoning intelligent control system provided in this embodiment is largely the same as the whole-house environment zoning intelligent control system provided in Embodiment 1. The difference is that in this embodiment, the sensor 14 integrated in the zoning control panel in each room 1 also includes a PM2.5 concentration sensor, a temperature sensor, and a humidity sensor, which are used to monitor the temperature and humidity in the room 1. Each room 1 is equipped with an air conditioner, an air purifier, a humidifier, and a dehumidifier. The zoning control panel 12 is also connected to the air conditioner, air purifier, humidifier, and dehumidifier in the room 1 to control the operation of the air conditioner, air purifier, humidifier, and dehumidifier. If the temperature sensor detects that the temperature in room 1 is higher than the set range, the zone control panel 12 controls the air conditioner to turn on to achieve cooling, and controls the air conditioner to turn off when the temperature is lower than the set range; if the humidity sensor detects that the humidity in room 1 is lower than the preset range value, the zone control panel 12 controls the dehumidifier to turn off and controls the humidifier to turn on; if the humidity sensor detects that the humidity in room 1 is higher than the preset range value, the zone control panel 12 controls the humidifier to turn off and controls the dehumidifier to turn on; if the PM2.5 concentration sensor detects that the PM2.5 concentration in room 1 is higher than the preset range value, the zone control panel 12 controls the air purifier to turn on.

[0037] Of course, in other embodiments, the sensor 14 can also be equipped with a VOC sensor or the like to control the operation of devices such as the fresh air unit 21 and the air purifier; it can be added or removed according to actual needs.

[0038] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
