Description

Technical Field

[0001] The utility model relates to the technical field of a range hood control system, and more specifically, to a control system for a range hood of doors and windows. Background Art

[0002] During the operation of a range hood, the oil fume pollution generated during cooking is discharged outdoors. However, during the operation of the range hood, a relatively airtight space will be formed indoors. When the range hood or exhaust fan extracts oil fume, it is necessary to extract the gas outdoors. However, after the initial extraction, the indoor is in a slightly negative pressure state, and the extraction process will be relatively difficult. In order for the range hood to operate normally, it is necessary to form an environment where air is continuously filled indoors. Generally, the range hood does not have a separate air supply device. Generally, air is extracted from pipes or other devices that communicate with the outside world indoors. The pipes that communicate with the outside world are generally the sewer pipes in the kitchen or the washroom. In order to maintain the indoor air pressure balance, extracting air from the sewer pipe causes the phenomenon of odor backflow in the toilet or washroom. Summary of the Utility Model

[0003] The technical problem to be solved by the utility model is:

[0004] To solve the problem that when the exhaust fan or range hood is turned on, due to the closed doors and windows, the indoor air pressure decreases, resulting in sewer odor backflow.

[0005] The technical solution adopted by the utility model to solve the above technical problem:

[0006] The utility model provides a control system for a range hood of doors and windows, including a range hood,

[0007] further including an electric window, a central controller, a air pressure detection device and a sewer outlet valve. The range hood is electrically connected to the central controller. The input end of the central controller is connected to the air pressure detection device, and the output end of the central controller is respectively connected to the electric window and the sewer outlet valve. The sewer outlet valve is used to open or close the connection state between the sewer outlet and the indoor. The central controller is used to control the electric window to open and close the sewer outlet valve when the air pressure detection device detects that the indoor air pressure is lower than the set threshold, so as to supplement the indoor air pressure and reduce the odor backflow.

[0008] Further, it further includes a water level sensor. The output end of the central controller is connected to the faucet switch, and the input end of the central controller is connected to the water level sensor, which is used to control the faucet switch to open when the air pressure detection device detects that the indoor air pressure is lower than the set threshold, and when the water level sensor detects that the water level reaches the preset height, transmit a signal to the central controller to control the faucet switch to close.

[0009] Further, a control switch is provided on the range hood. The control switch is connected to the central controller and is used to turn on or off the control system.

[0010] Further, a temperature sensor and a smoke sensor are further included. Both the temperature sensor and the smoke sensor are connected to the central controller. When the smoke sensor detects that the indoor flue gas exceeds the set threshold, the central controller controls the electric window to open. When the temperature sensor detects that the indoor temperature is lower than the set threshold, the central controller controls the electric window to close.

[0011] Further, a warning device is further included. The warning device is connected to the central controller and is used to warn that the indoor air pressure is lower than the set threshold.

[0012] Further, the warning device is a sound warning or a flash warning.

[0018] For a control system of a range hood for doors and windows of the present utility model, the input end of the central controller is connected to the air pressure detection device, and the output end is respectively connected to the electric window and the drain valve. When the range hood is started, the indoor air is extracted, creating a slightly negative pressure state. When the air pressure detection device detects that the indoor air pressure is lower than the preset threshold, a signal is sent to the central controller, and the central controller controls the opening of the electric window and the closing of the drain valve. Through the doors and windows or the electric doors and windows, the indoor and outdoor are in a connected state, ensuring that the indoor air pressure returns to the normal standard. By closing the drain valve, the connection state between the drain pipe and the indoor is cut off, preventing air from being extracted through the drain pipe and causing the problem of sewer odor backflow.

Such direction nouns do not constitute a limitation to the present utility model.

[0026] In order to make the above-mentioned objects, features, and advantages of the present utility model more obvious and understandable, the following detailed description of the specific embodiments of the present utility model will be given with reference to the drawings.

[0027] Specific Embodiment 1: Combining Figures 1 to 3 As shown, the present utility model provides a control system of a range hood with doors and windows, including a range hood 1, and also including an electric window 2, a central controller 10, an air pressure detection device 12, and a drain outlet valve 5. The range hood with doors and windows 1 is connected to the central controller 10. The input end of the central controller 10 is connected to the air pressure detection device 12, and the output end is respectively connected to the electric window 2 and the drain outlet valve 5. The drain outlet valve is used to open or close the connection state between the drain outlet and the house interior. The central controller 10 is used to control the electric window 2 to open and close the drain outlet valve when the air pressure detected by the air pressure detection device 12 is lower than the set threshold, so as to supplement the indoor air pressure and reduce the backflow of peculiar smell.

[0028] It is connected to the air pressure detection device 12 through the input end of the central controller 10, and the output end is connected to the electric window 2 and the drain valve 5. When the range hood 1 is started, the indoor air is extracted to create a slightly negative pressure state. When the air pressure detection device 12 detects that the indoor air pressure is lower than the preset threshold, it sends a signal to the central controller 10. The central controller 10 controls the opening of the electric window 2 and the closing of the drain valve. Through the electric window 2, the indoor and outdoor are in a connected state, ensuring that the indoor air pressure returns to the normal standard; by opening the drain valve 5, the connection between the drain pipe and the indoor is cut off, preventing air from being extracted through the drain pipe and causing the problem of sewer odor backflow; the structure of this implementation scheme is simple and reasonable. By opening the electric window 2 and closing the drain valve 5, the problem of negative pressure environment generated indoors when the range hood 1 works can be solved without modifying the exhaust pipe, saving decoration costs, and having practical application and promotion value.

[0029] Specific implementation scheme two: Combined with Figures 1 to 3 As shown, it further includes a water level sensor 11. The output end of the central controller 10 is connected to the faucet switch 9, and the input end is connected to the water level sensor 11, which is used to control the opening of the faucet switch 9 when the air pressure detection device 12 detects that the low pressure is lower than the set threshold, and when the water level sensor 11 detects that the water level reaches the preset height, it transmits a signal to the central controller 10 to control the closing of the faucet switch 9. On the basis of closing the drain valve 5 in the specific implementation scheme one, using water to seal the drain can achieve a further sealing effect, effectively preventing the phenomenon of sewer odor backflow caused by the drain valve 5 not being tightly closed. The other combinations and connection relationships of this implementation scheme are the same as those of the specific implementation scheme one.

[0030] Specific implementation scheme three: Combined with Figures 1 to 3 As shown, a control switch 3 is provided on the range hood 1, and the control switch 3 is connected to the central controller 10, which is used to realize the overall opening or closing of the control system.

[0031] Specific implementation scheme four: Combined with Figures 1 to 3As shown in the figure, it further includes a temperature sensor 8 and a smoke sensor 6. Both the temperature sensor 8 and the smoke sensor 6 are connected to the central controller 10. When the smoke sensor 6 detects that the indoor flue gas exceeds the set threshold, the central controller 10 controls the electric window 2 to open. When the temperature sensor 8 detects that the indoor temperature is lower than the set threshold, the central controller 10 controls the electric window 2 to close. The setting of the smoke sensor 6 can reduce the risk coefficient when a large amount of oil fume is generated during cooking or even a fire is caused. By opening the doors and windows, the oxygen content in the indoor air is maintained. It should be noted that the threshold set by the smoke sensor 6 is the amount of flue gas exceeding that generated during normal cooking. The temperature sensor 8 is set to prevent the problem of too low indoor temperature caused by opening the electric window 2 in winter. The other combinations and connection relationships of this implementation scheme are the same as those of the specific implementation scheme one.

The early warning device 7 is used to prompt the user that the indoor air pressure is lower than the set threshold, and to open or close the electric window 2 and the drain valve 5. The other combinations and connection relationships of this implementation scheme are the same as those of the specific implementation scheme one.

[0033] Specific implementation scheme six: Combined with Figures 1 to 3 As shown in the figure, the early warning device 7 is a sound warning or a flash warning, and can display the category of the warning through different sounds or flashes of different colors.

[0039] Working Principle: When the range hood 1 is started, it mainly extracts indoor air, and the indoor pressure decreases. When the air pressure detection device 12 detects that the indoor pressure drops to a preset threshold, it transmits a signal to the central controller 10. Through the central controller 10, the electric window 2 and the faucet are controlled to open, the drain valve 5 is closed, the electric window 2 is opened to connect the indoor and outdoor, ensuring that the indoor pressure is balanced with the outdoor pressure. The passage between the drain and the outside is closed through the drain valve 5, the faucet is opened, and the sink is filled with water. When a certain water level is reached, a signal is transmitted to the central controller 10 through the water level sensor 11, and the central controller 10 controls the faucet to close, further isolating the drain from the outside to prevent the backflow of odors from the drain; during the operation of this control system, it can be opened and closed through the self-control opening and closing button 4 of the drain valve without affecting the normal use of the sink.
