[0039] The embodiments of the present disclosure are described in detail below, and examples of the embodiments are shown in the accompanying drawings, in which the same or similar reference signs represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the accompanying drawings are exemplary and are intended to explain the present disclosure, and cannot be understood as limiting the present disclosure.

[0040] The design environment or application scenario of the present scheme is described first below.

[0041] In embodiments of this disclosure, at least two detection devices can be installed on a home appliance. The home appliance may include a main body, on which at least two detection devices can be installed. In embodiments of this disclosure, the type of home appliance is not limited; it can be any household appliance. The home appliance may also be a detection assembly with at least two detection devices, capable of being installed on the home appliance for detection.

[0042] In some embodiments, such as Figure 1 As shown, the home appliance includes a main body (101) and at least two detection devices (102). The lateral distance (installation interval) between any two detection devices is d meters, where d is greater than zero.

[0043] In some embodiments, at least one of the at least two detection devices may be installed at an angle, for example, with an angle N relative to the reference surface. Figure 3 A schematic diagram of the detection device and the reference plane is shown. Wherein, as Figure 3 As shown in (a), the reference surface (1) can be a plane passing through the detection section (103) of at least two detection devices (102), and the reference surface (1) extends along the length direction of the detection device (102). For example, the detection section can be the transmitting end of the detection device, such as a transmitting antenna, or the center of the detection device. In some examples, such as... Figure 3 As shown in (a), when the main body of the home appliance is a circular cabinet air conditioner, the mounting part of the main body of the home appliance is not a plane. The detection device is installed on the circular cabinet panel (2). The reference surface (1) is a plane passing through the detection part (103) of at least two detection devices (102). The reference surface (1) extends along the length direction of the detection device (102). For example, the length direction can be from the inside to the outside or from the outside to the inside, perpendicular to the plane. Figure 3 Paper (or display) Figure 3 The orientation of the screen. In some examples, such as Figure 3 As shown in (b), the main body of the home appliance has a mounting section (104), and at least two detection devices (102) are mounted on the mounting section (104). The main body of the home appliance can be a square cabinet air conditioner, a ducted air conditioner, or a wall-mounted air conditioner. The detection devices are mounted on the panel of the square cabinet air conditioner, the panel of the ducted air conditioner, or the panel of the wall-mounted air conditioner. The reference surface (1) is parallel to the plane where the mounting section (104) is located. Optionally, the mounting section (104) can be a mounting plate, and the aforementioned reference surface (1) is parallel to the mounting plate. In some examples, when the home appliance is a ducted air conditioner, a wall-mounted air conditioner, or a square cabinet air conditioner, the mounting plate is an air conditioner panel, and at least two detection devices are mounted on the air conditioner panel.

[0044] like Figure 4As shown, the household appliance is a detection component suitable for installation on household appliances, wherein the main body (101) of the household appliance is a mounting shell. The detection device (102) is installed inside the mounting shell.

[0045] In some embodiments, w is a constant (in degrees) within a preset range.

[0046] In some embodiments, L is a constant within a preset range.

[0047] The relationship between d, w, N, and L can be expressed by the following formula:

[0048] (Equation 1).

[0049] like Figure 1 As shown, the following explanation uses two detection devices as an example. In application scenarios where the total detection range is greater than 180°, the two detection devices arranged on the main body of the home appliance (taking an air conditioner as an example) have an installation interval of d meters, and the tilt angle of the two detection devices is N. N has an overlap angle M with a constant w. The main body of the home appliance has a constant L in the longitudinal direction.

[0050] like Figure 2 As shown, two detection devices are used as an example for illustration. In an application scenario where the total detection range is [150°, 180°), the two detection devices arranged on the main body of the home appliance are spaced d meters apart, and the tilt angle of the two detection devices is N. There is a leakage angle M between N and the constant w. The main body of the home appliance has a constant L in the longitudinal direction.

[0051] This disclosure proposes a household appliance, comprising: a main body of the household appliance; at least two detection devices installed on the main body of the household appliance, wherein the at least two detection devices have an installation interval d meters between them, where d is at least 0.1.

[0052] In some embodiments, the value of d ranges from [0.1, 3].

[0053] For example, such as Figure 1 As shown in the schematic diagram, since there may be interference between at least two detection devices, especially when the frequencies of the two detection devices are the same or both are within the preset range, in order to avoid interference values ​​or affect the detection accuracy when at least two detection devices detect simultaneously, the lateral distance d between at least two detection devices shall not be less than 0.1.

[0054] In some embodiments, d is less than or equal to a length value of the air conditioning device or a length value of the ducted air conditioner or a length value of the air deflector panel, wherein the maximum length value of the air conditioning device or the ducted air conditioner or the air deflector panel is 3 meters, and thus d can be arranged as 3. In this arrangement, the detection device can be installed on both sides of the air conditioning device, which maximizes the use of the internal space of the air conditioning device, while facilitating the detection of the detection device and avoiding interference with the detection caused by other components when the detection device is arranged in the middle of the air conditioning device. Arranging the detection device on the air conditioning device at the maximum distance can achieve the integration of the detection device and the air conditioning device, and the product uniformity is good.

[0055] In some embodiments of the present disclosure, d is in the range of [0.1, 0.8]. In this embodiment, the air conditioning device is a 1.5 ton ducted air conditioner.

[0056] In some embodiments, 1.5 tons means that the cooling capacity of the air conditioning device is in the range of 3500 watts, and the power consumption is 1094 watts.

[0057] Therefore, when the air conditioning device is a 1.5 ton ducted air conditioner, the installation interval of the at least two detection devices on the installation plate is in the range of [0.1, 0.8] meters. Thus, the arrangement of the at least two detection devices of the 1.5 ton ducted air conditioner is achieved, which on the one hand enhances the detection range, and on the other hand avoids interference between the at least two detection devices.

[0058] In some embodiments, d is in the range of [0.1, 1.46]. In this embodiment, the air conditioning device is a 3 ton ducted air conditioner.

[0059] In some embodiments, 3 tons means that the cooling capacity of the air conditioning device is in the range of 7100 to 7600 watts.

[0060] Therefore, when the air conditioning device is a 3 ton ducted air conditioner, the installation interval of the at least two detection devices on the installation plate is in the range of [0.1, 1.46] meters. Thus, the arrangement of the at least two detection devices of the 3 ton ducted air conditioner is achieved, which on the one hand enhances the detection range, and on the other hand avoids interference between the at least two detection devices.

[0061] In some embodiments, d is in the range of [0.1, 0.3]. In this embodiment, the air conditioning device is a cabinet air conditioner.

[0062] In some embodiments, d is in the range of [0.1, 0.5]. In this embodiment, the air conditioning device is a cabinet air conditioner.

[0063] Therefore, when the household appliance body is a cabinet air conditioner, the installation interval of the at least two detection devices on the installation plate is in the range of [0.1, 0.3] meters or [0.1, 0.5] meters. Thus, the arrangement of the at least two detection devices of the 3P ducted air conditioner is achieved, which on the one hand enhances the detection range and on the other hand avoids interference between the at least two detection devices.

[0064] In some embodiments, the distance between the at least one detection device and the air outlet is greater than 0.5 meters. In order to ensure the accuracy of detection and avoid interference, in the air conditioning system, the detection device can be used for environmental perception and wind direction control. If the distance between the detection device and the air outlet is less than 0.5 meters, the strong airflow of the air outlet may interfere with the measurement accuracy of the radar, resulting in inaccurate data. Therefore, the distance between the at least one detection device and the air outlet is greater than 0.5 meters, which can reduce airflow interference and ensure that the detection device can accurately perceive the surrounding environment, thereby achieving more accurate control.

[0065] It should be understood that the embodiments described above with respect to d are applicable to Figure 1 or 2.

[0066] In order to achieve different overall detection ranges of the at least two detection devices, the following two schemes can be used:

[0067] In some embodiments, as shown in Figure 1 , at least one of the at least two detection devices has an inclination angle N with respect to the reference surface, wherein when the at least two detection devices are respectively rotated to the inclination angle N, the overall detection range of the at least two detection devices is not less than 180°.

[0068] In this embodiment, the value range of N is (30°, 40°).

[0069] In some embodiments, as shown in Figure 2 , at least one of the at least two detection devices has an inclination angle N with respect to the reference surface, wherein when the at least two detection devices are respectively rotated to the inclination angle N, the overall detection range of the at least two detection devices is not less than 180° and greater than or equal to 150°.

[0070] In this embodiment, the value range of N is 35°.

[0071] In some embodiments, the reference surface is a plane passing through the detection portions of the at least two detection devices, and the reference surface extends along the length direction of the detection device. As shown in Figure 3 , a schematic view of a detection device and a reference surface.

[0072] In some embodiments, when the household appliance is a round cabinet air conditioner, the reference surface is a plane passing through the detection portions of the at least two detection devices, and the reference surface extends along the length direction of the detection devices.

[0073] In some embodiments, the household appliance body includes a mounting portion, and the reference surface is parallel to a plane in which the mounting portion is located.

[0074] In some embodiments, the reference surface of the ducted air conditioner is parallel to a plane in which the mounting portion is located. Figure 3 As shown in the schematic view of (b) in FIG. 1.

[0075] The following describes the embodiments shown in Figure 1 and Figure 2 respectively.

[0076] For the embodiment shown in Figure 1 , in order to ensure that the overall detection range of the household appliance is not less than 180°, the following conditions need to be met:

[0077] (Formula 2);

[0078] ;

[0079] .

[0080] Therefore, it can be concluded that , , . According to the regulations, 100°≤w<180°, so the value range of w is [max(180°-2N, 2N, 100°), 180°).

[0081] In combination with Figure 1 and the above description, the following further describes the design of the household appliance, so that the detection range of the household appliance is not less than 180°.

The detection range of the household appliance is not less than 180°.

[0083] In combination with the above formulas (Formula 2), (Formula 3), (Formula 4), it can be concluded that N<180°-2d ; N>2d According to the regulation, 100°≤w<180°, and thus the value range of N is within (0°, 90°). In the case that N takes any value within (0°, 90°), the overall detection range of the household appliance can be ensured to be 180° or above.

[0084] In combination with the above description, the design of the household appliance is further described below, and the relationship between d and N is given, so that the detection range of the household appliance is not less than 180°.

[0087] Therefore, the tilt angle N and the distance d of the two detection devices need to satisfy <1.5, that is . When 0°<N<90° and d≥0.1, the above formula is established.

[0109] The derivation process of the embodiment is similar to the above embodiment, and will not be described here.

[0110] In the embodiment, the household appliance body is a cabinet air conditioner.

[0111] In the above embodiment, when the home appliance body is a cabinet air conditioner, the installation interval of the two detection devices installed on the installation plate of the home appliance body is d meters, d≥0.1, and when the value range of N is (0°, 90°), the vertical distance of the blind area is not more than 0.5 meters, so that the overall detection range of the two detection devices is not less than 180°, so as to maximize the functional effect of the two detection devices and detect a larger range.

[0163] In summary, by determining the relationship between d and N, the overall detection range of the home appliance device can be realized to cover [150°, 180°).

[0164] In some embodiments, by the angular relationship between N and w, when it is determined that N in the at least two detection devices satisfies the following formula, the overall detection range of the home appliance device can be greater than or equal to 150° and less than 180°:

[0165] ; (Formula 2-1)

[0166] ; (Formula 2-2)

[0167] ; (Formula 2-3)

[0168] ; (Formula 2-4)

[0169] wherein, w is at least one value in [100°, 175°), and the value range of N is (0°, 40°].

[0170] Specifically, in order to satisfy 180° detection, the minimum deflection angle of N satisfies (Formula 2-1) and (Formula 2-2), in order to make the detection areas of the at least two detection devices overlap and cross, and avoid the blind area being infinite, (Formula 2-3) and (Formula 2-4) need to be satisfied, and w can be at least one value in [100°, 175°). From the above formulas, it can be obtained that: when w is 100°, the value range of N is 0°≤N<40°, when w is 175°, the value range of N is 0°<N≤2.5°, and therefore, when w is [100°, 175°), N satisfies 0°<N≤40°.

[0171] In some embodiments, when N in the at least two detection devices satisfies the following formula, the overall detection range of the home appliance device can be greater than or equal to 150° and less than 180°:

[0173] ; (Formula 3-2)

[0174] ; (Formula 3-3)

[0175] ; (Formula 3-4)

[0176] wherein, N is in the range of [5°, 31.5°] when w is in the range of [102°, 140°].

[0177] Specifically, in order to achieve a detection range between [150°, 180°), N needs to satisfy: , d meters, where d satisfies 0.1≤d≤1.5, and thus, from the above formula 1, (Formula 3), Thus, w≥102°, from formula 2 and formula 3, when w is 102°, N is 24°, when w is 140°, N is in the range of 5°≤N≤20°, when w is 120°, N is in the range of 15°≤N≤30°, when w is 117°, N is in the range of 16.5°≤N≤31.5°, and in summary, when w is at least one value in the range of [102°, 140°], d is in the range of 0.1≤d≤1.5, and N is in the range of [5°, 31.5°].

[0179] (Formula 4-1)

[0180] (Formula 4-2)

[0181] (Formula 4-3)

[0182] (Formula 4-4)

[0183] wherein, w is at least one value in the range of [100°, 140°], and N is in the range of [5°, 40°].

[0184] Specifically, in order to make the detection range greater than or equal to 150° and less than 180°, the minimum deflection angle of N satisfies (Formula 4-1) and (Formula 4-2), and in order to make the detection area overlap, prevent the intersection blind area from being infinite, N needs to satisfy (Formula 4-3) and (Formula 4-4), according to w is at least one value in the range of [100°, 140°], and thus, from the above formula, we can get: , when w is 100°, N is in the range of 25°≤N≤40°, when w is 140°, N is in the range of 5°<N<20°, when w is 120°, N is in the range of 15°≤N≤30°, and thus, in N satisfies 5°≤N≤40°.

[0186] In the above embodiment, the at least two detection devices are symmetrically arranged at the left and right ends of the household appliance.

[0187] For example, the two detection devices are symmetrically arranged at the left and right ends of the household appliance.

[0188] For example, the two detection devices are symmetrically arranged at the left and right ends of the household appliance.

[0189] In some embodiments, the at least two detection devices are arranged back to back.

[0190] In some embodiments, N in the at least two detection devices satisfies the following formula, which can make the overall detection range of the household appliance greater than or equal to 150° and less than 180°:

[0191] ; (formula 6-1)

[0193] ; (formula 6-3)

[0194] ; (formula 6-4)

[0195] wherein, is at least one value in [100°, 140°], and the value range of N is (0°, 31.5°].

[0196] Specifically, in order to realize the detection area between [150°, 180°), N needs to satisfy: , (formula 2), w is at least one value in [100°, 140°], the distance d between the at least two detection devices satisfies 0.1≤d≤1.5, therefore, from the above formula 1 , , When d = 1.5, has a maximum value, has a minimum value, so (Formula 3), from Formula 2 and Formula 3, when w is 100°, the value of N is 10°≤N≤23°, when w is 140°, the value of N is -10°≤N≤20°, when w is 120°, the value of N is 0°≤N≤30°, when w is 117°, the value of N is 1.5°≤N≤31.5°, and in summary, when w is at least one value in [100°, 140°], d is 0.1≤d≤1.5, and N satisfies (0°, 31.5°].

[0197] In some embodiments, the household appliance is asymmetrically arranged. For example, the two millimeter wave radars of the air conditioner are asymmetrically arranged at the left and right ends of the air conditioner, respectively. Or the two millimeter wave radars of the air conditioner are asymmetrically arranged at the left and right ends of the air conditioner in the form of outer eight.

[0198] For the value of N, the left radar rotates clockwise as positive, and counterclockwise as negative. The right radar rotates clockwise as negative, and counterclockwise as positive.

[0199] In some embodiments, -10° can be the case that the left radar rotates counterclockwise by 10°, or the right radar rotates clockwise by 10°.

[0200] In some embodiments, at least one of the at least two detection devices is a millimeter wave radar.

[0201] In some embodiments, the frequencies of the at least two detection devices are different.

[0202] In some embodiments, the frequencies of the at least two detection devices are within a preset range or the same.

[0203] In some embodiments, the preset range can be 24GHz~24.25GHz.

[0204] In some embodiments, the frequency of the millimeter wave radar can also be 24GHz~77GHz, specifically, it can be 24GHz, 60GHz and 77GHz.

[0205] In some embodiments, the household appliance is a detection assembly suitable for being installed on a household appliance, and the household appliance body is a mounting shell.

[0206] For example, the at least two detection devices have been assembled on the household appliance, which can be directly installed on the household appliance. To achieve the detection function.

[0207] In conjunction with the above embodiments, in some embodiments, the installation angle of each detection device in the vertical direction can be designed.

[0208] like Figure 5 and 6 The schematic diagram shows that the detection device has a first installation angle α, which is the angle between the main plane of the detection device and a first reference line. The first reference line can be a vertical line.

[0209] Figure 6 The w' shown is a constant (in degrees) within a preset range. It should be understood that... Figure 1 , 2 The constant w shown is Figure 6 The values ​​or ranges of the constant w' shown are different.

[0210] In some embodiments, it may be based on Figure 6 In the corresponding embodiment, the value of the constant w' is selected as the preset detection angle of a single radar, or the value of w' can be used to select the vertical detection angle of a single radar, or w' can represent the vertical detection angle of a single radar.

[0211] In some embodiments, the first installation angle [1.4°, 90°].

[0212] In some embodiments, the first installation angle Satisfy the following formula: ,in, It is at least one of the values ​​in [50°, 90°].

[0213] In some embodiments, A can be a constant (in meters), and the maximum value of A is 2 meters.

[0214] In some embodiments, A = Hh, where the value of H can be in the range of [2,3] and the value of h can be in the range of [1,2].

[0215] In some embodiments, the constant L can be 1.5 meters or 1.2 meters.

[0216] In some embodiments, the first installation angle The range is [1.4°, 60°].

[0217] In some embodiments, the first installation angle The range is [10°, 60°].

[0218] In some embodiments, the first installation angle The range is [10°, 45°].

[0219] In some embodiments, the first installation angle is 10°.

[0220] In some embodiments, the first installation angle is 35°.

[0221] In some embodiments, the first installation angle can be an acute angle, the first installation angle is related to the installation height of the home appliance, or the first installation angle is related to the area size where the home appliance is installed. In other words, the first installation angle can be adjusted according to the installation height of the home appliance and / or the area size where the home appliance is installed.

[0222] For example, as shown in the schematic diagram, Figure 6 the angle between the main plane of any detection device and the vertical line is , the installation height of the home appliance is H, and the area size where the home appliance is installed is S1.

[0223] In Figure 6 , the constant Q is related to w', and for example, the normal maximum detection distance of the detection device can be determined according to the constant Q. When the intersection of Q and S is exactly equal to the distance h from the ground, it is the optimal angle of , at this time, the detection device can detect a person in front of the home appliance, and when continues to decrease, the detection device cannot detect the person, and therefore, at this time, it is the minimum value of .

[0224] In Figure 6 , the constant L can be a preset value, and the longitudinal detection blind area of the detection device can be determined according to the value of the constant L.

[0225] In some embodiments, the constraint relationship formed by L and S is determined, the constraint of L and S is related to H and S1, and as increases, L decreases, when is 0, L is maximum, and when continuously increases, the limit value of L is 0; when continuously decreases, the value of L increases, and the value of S also increases accordingly.

[0226] In some embodiments, the projection length of the normal maximum detection distance of the detection device on the horizontal plane and the first installation angle are inversely proportional, wherein as the projection length increases, the first installation angle decreases; the length of the perception blind area and the first installation angle are inversely proportional, wherein as the length of the perception blind area increases, the first installation angle decreases.

[0227] For example, as shown in the schematic diagram, Figure 5The schematic diagram shows that when determining the vertical blind zone distance, the minimum angle of the upper and lower air guide plates of the household appliance (such as an air conditioner) is considered to ensure that the detection area of ​​the detection device covers the area blown by the household appliance, i.e., L≤L1. Therefore, the vertical tilt angle of the detection device is determined. The relationship between the minimum angle b of the upper and lower air guide plates can be .

[0228] In some embodiments, a change in the first installation angle will cause a change in L, as... As the value increases, L will decrease. To prevent missed detection of targets in front of the air conditioner, the blind zone should be minimized.

[0229] For example, If 2 ≤ H ≤ 3 and h ≤ 1.8, then S ≤ 8 can be achieved. Therefore, when H = 2, h = 1.8, and the maximum detection range of a single radar is S = 8, Take the minimum value. ,Right now °. For example Figure 6 The diagram shown is as follows. The maximum value is 90°, therefore we can obtain The range is greater than or equal to 1.4° and less than or equal to 90°. Within this range, the functional effect of the detection device can be maximized.

[0230] In some embodiments, the number of detection devices on the household appliance may be one, two or more, and this disclosure does not limit this.

[0231] In summary, this disclosure has the following technical effects:

[0232] 1. When at least two detection devices are arranged on household appliances, the detection range and detection effect can be improved, but interference may occur. In order to avoid interference or affect the detection accuracy when detection devices on the same frequency are detected at the same time, when the detection devices are arranged on the left and right, the horizontal spacing d meters should not be less than 0.1 meters, so as to achieve an overall detection range of more than 180° while avoiding interference on the same frequency.

[0233] 2. In such Figure 1 With the aforementioned arrangement, the overall detection range of multiple detection devices can be realized. For example, the horizontal tilt angle N of a single detection device is within (0°, 90°), thereby enabling the detection of household appliances at angles of 180° and above; in situations such as Figure 2 With the arrangement shown, the horizontal tilt angle N of a single detection device is within (0°, 40°], thereby enabling the detection of household appliances at [150°, 180°].

[0234] 3. Depending on the product type and the different values ​​of the constant L, the relationship between the installation interval d meters between at least two detection devices and their respective horizontal tilt angle N can be obtained, thereby optimizing the layout of the detection devices for home appliances.

[0235] 4. For cases where the total detection range reaches 180° or more, in order to prevent the possible deviation between the theoretical horizontal detection angle and the actual horizontal detection angle of the detection device, and to avoid the decrease in detection accuracy in the edge area of ​​the detection angle, in order to ensure that the detection range of 180° or more is fully realized, a certain margin angle M (M>0°) can be reserved for the tilt angle of the left and right detection devices. M can be 5°.

[0236] 5. By designing the first installation angle α in the vertical direction, the detection range of the detection device in the vertical direction was optimized.

[0237] In summary, by designing the parameters of at least two detection devices on home appliances and the correlation between these parameters, it is possible to quickly calculate the optimal distribution of detection devices when installing dual detection devices on home appliances (such as air conditioners), thereby optimizing the detection range and avoiding interference. By comprehensively considering factors such as the maximum horizontal detection angle, minimum blind zone, and minimum interference, a rational arrangement can be implemented to further maximize the effectiveness of the sensing function.
