The embodiments in this document are described in a progressive manner. Each embodiment focuses on the differences from other embodiments. The same and similar parts between the embodiments can be referred to each other. For the methods and products disclosed in the embodiments, since they correspond to the method parts disclosed in the embodiments, the description is relatively simple, and the relevant parts can be referred to the description in the method part.

Referring to FIGS. 1 and 2 together, according to an embodiment of the present disclosure, the purification device includes a plurality of purification grids and a control unit, and the control unit can selectively control the operation of any number of purification grids.

Since the purification device is divided into multiple purification grids, and the number of purification grids can be selected according to requirements, the purification capacity of the purification device can be selected according to the purification amount, so that the purification capacity of the purification device matches the required purification capacity, Improve energy efficiency.

In some optional embodiments, the purification efficiency of each purification grid is the same. When calculating the purification efficiency of the purification grid, the amount of calculation can be greatly reduced, which is convenient for quickly determining the number of purification grids required, so that it can be set A reasonable number of purification grids can meet the current purification requirements and increase the speed of regulation.

In some alternative embodiments, at least two purification grids have different purification efficiencies. By setting multiple purification grids to have different purification efficiency, the diversity of purification grid networking can be improved, and the rationality of purification grid selection can be improved, so that the purification capacity and required after purification grid networking The purification capacity is more matched, improving energy efficiency, avoiding waste of resources and excess capacity.

The purification device further includes a detection unit configured to detect the PM2.5 value in the air, and the control unit determines the number of operating purification grids based on the detected PM2.5 value and the target PM2.5 value.

The purification capacity required by the purification device is determined by the current PM2.5 value in the air and the target PM2.5 value, so the PM2.5 value in the current air can be accurately obtained by the detection unit, and the internal memory of the purification device can also be obtained Target PM2.5 value, the target PM2.5 value can be set by the user, or can be set by the controller according to the user's usage habits, or the controller built-in strategy.

Referring to FIG. 1 and FIG. 2 together, according to an embodiment of the present disclosure, the control method of the purification device includes: acquiring the PM2.5 value in the current air; according to the PM2.5 value in the current air and the target PM2.5 value The difference between them determines the required purification grid; the determined purification grid is operated.

The purification device of the present disclosure includes a plurality of purification grids, and multiple independent control purification grids can be used to form a multi-module assembly mode to realize networked module networking, and can perform single grid control and multi-grid networking control. Arbitrary network control can better meet the current air purification capacity requirements, and can avoid the problem of excess purification capacity of the purification device. When the current PM2.5 value is less than or equal to the target PM2.5 value, the air conditioner continues to operate and does not operate the purification device, when the current air PM2.5 value is greater than the target PM2.5 value, then According to the difference between the PM2.5 value in the current air and the target PM2.5 value, the purification grid to be operated is determined, and the determined purification grid is networked.

In some optional embodiments, the purification efficiency of each purification grid is the same, and the step of determining the purification grid to be operated according to the difference between the current PM2.5 value and the target PM2.5 value includes: The difference determines the number of purification grids required to operate; select a corresponding number of purification grids for networking; operate the purification grids for networking.

The number of purification grids for networking is determined by the following method:

W _x = S / η * (QQ ₀ )

Where η * (QQ ₀ ) is the amount of purification that can be provided per unit of purification grid under the current air environment, and S is the amount of purification that the purification device needs to complete per unit time, and the ratio between the two is the required purification The number of grids.

Through the above method, the number of purification grids required in the current air environment can be quickly calculated, so that the required purification grids can be networked, and then during the operation of the air conditioner, the purification grids of the network can be controlled to work. The purification grid that does not form a network does not work, and meets the purification capability requirements under the current air environment.

In another embodiment, at least two purification grids have different purification efficiencies, and the step of determining the purification grid to be operated according to the difference between the current PM2.5 value and the target PM2.5 value includes: Number the purification grid; determine the purification efficiency corresponding to each number; determine the purification grid to be operated according to the difference.

The step of determining the required purification grid networking based on the difference includes: the number of purification grids of the network is x, where the purification efficiency of x-1 purification grids <required purification efficiency <x purifications The purification efficiency of the grid.

In this embodiment, the total number of purification meshes is i, the number of purification meshes of each network is Wi, and the number of purification meshes of the network is Wx, where x is the number of purification meshes participating in the network, Taking i = 5, x = 3 as an example, the number of purification grids is W1, W2, W3, W4, W5 in order, and the number of purification grids participating in the network is 3, where the purification efficiency of W3 is η, and the purification of W1 The efficiency is 0.9η, the purification efficiency of W2 is 0.9η, the purification efficiency of W4 is 1.2η, the purification efficiency of W5 is 1.3η, and the required purification efficiency is 3η, so you can choose the purification grid number for networking at this time The networking is W1, W2, W4; W2, W3, W4; W1, W3, W4; W1, W2, W5; W2, W3, W5; W2, W4, W5; W3, W4, W5, and any two purifications In the grid network, the purification efficiency is W4 + W5 = 2.6η <3η, so x should be 3, that is, the number of purification grids in the network is 3. At this time, the above three purification networks can be arbitrarily selected The grids with a purification efficiency of> 3η can meet the purification requirements of the current environment and can effectively avoid energy waste.

Refine the above purification grid numbering network, where the purification efficiency of the above network is 3η; 3.1η; 3.1η; 3.1η; 3.2η; 3.4η; 3.5η, as can be seen from the above purification efficiency Although the above networking meets the air purification requirements in the current environment, and the number of purification grids required is the smallest, there are still differences between the purification efficiency under different networking. Again, you can choose between Purification grid networking with close purification efficiency needs to be met. In this embodiment, the selection of W1, W2, W4 networking just meets the purification efficiency requirements in the current environment, so the purification efficiency of the purification grid networking can be used. Makes the purification grid network work fully, can accurately control the use of consumables and use time, etc., to achieve precise and intelligent control, without wasting efficiency and reducing purification effects.

Of course, the second, third, and fourth groups of the above-mentioned purification grid networking have relatively similar purification efficiencies and required purification efficiencies, and can also be selected preferentially. Through the above comparison, it is possible to select a more appropriate purification grid network under the same number of networking conditions, and improve the utilization efficiency of the purification grid network.

It should be understood that the present disclosure is not limited to the processes and structures already described above and shown in the drawings, and various modifications and changes can be made without departing from the scope thereof. The scope of the present disclosure is limited only by the appended claims.
