[0042] Embodiments of this disclosure are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0043] The design environment or application scenario of this solution will be described below.

[0044] 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.

[0045] In some embodiments, such as Figure 1 As shown, the household 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.

[0046] 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 3The schematic diagram of the detection device and the reference surface is shown. Wherein, as shown in (a) of Figure 3 , the reference surface (1) can be a plane passing through the detection part (103) of the at least two detection devices (102), and the reference surface (1) extends along the length direction of the detection device (102). Exemplarily, the detection part can be the transmitting end of the detection device, such as the transmitting antenna, or the center of the detection device. In some examples, as shown in (a) of Figure 3 , when the household appliance body is a circular cabinet air conditioner, the mounting part of the household appliance body is not a plane, the detection device is mounted on the circular cabinet panel (2), the reference surface (1) is a plane passing through the detection part (103) of the at least two detection devices (102), and the reference surface (1) extends along the length direction of the detection device (102), for example, the length direction can be the direction perpendicular to the inside-out or outside-in direction of Figure 3 the paper surface (or the screen of the display Figure 3 ). In some examples, as shown in (b) of Figure 3 , the household appliance body has a mounting part (104), and the at least two detection devices (102) are mounted on the mounting part (104), the household appliance body can be a square cabinet, a ducted air conditioner or a hanging machine, the detection device is mounted on the square cabinet panel, the ducted air conditioner panel or the hanging machine panel, and the reference surface (1) is parallel to the plane where the mounting part (104) is located. Optionally, the mounting part (104) can be a mounting plate, and the aforementioned reference surface (1) is parallel to the mounting plate. In some examples, when the household appliance is a ducted air conditioner, a hanging air conditioner or a square cabinet air conditioner, the mounting plate is an air conditioner panel, and the at least two detection devices are mounted on the air conditioner panel.

[0047] As shown in Figure 4 , the household appliance is a detection assembly suitable for being mounted on a household appliance, wherein the household appliance body (101) is a mounting shell. The detection device (102) is mounted in the mounting shell.

[0048] In some embodiments, w is a constant (unit: °) in a preset range.

[0049] In some embodiments, L is a constant in a preset range.

[0050] Then, the relationship between d, w, N and L can be represented by the following formula:

[0051] (Formula 1).

[0052] In combination with Figure 1 , the design of the household appliance described above is further described below, and the derivation process of the value range of w is given.

[0053] As shown in Figure 1As shown, the following explanation uses two detection devices as an example. The two detection devices, arranged on the main body of a household appliance (taking an air conditioner as an example), are spaced d meters apart. The inclined installation angle of the two detection devices is N, and N coincides with a constant w at an angle M. The main body of the household appliance has a constant L in the longitudinal direction.

[0054] To ensure that the overall detection range of home appliances is not less than 180°, the following must be met:

[0055] (Equation 2);

[0056] ;

[0057] .

[0058] Therefore, it can be concluded that , , According to the rule, 100°≤w<175°, therefore the range of values ​​for w is [max(180°-2N, 2N, 100°), 175°).

[0059] Combination Figure 2 The design of the home appliance described above will be further described below, and the derivation process of the range of values ​​for w will be given so that the detection range of the home appliance is greater than or equal to 150° and less than 180°.

[0060] like Figure 2 As shown, two detection devices are used as an example for illustration. The two detection devices are arranged on the main body of the appliance with a distance of d meters between them. The inclined installation angle of the two detection devices is N, and there is a leakage angle M between N and the constant w. The main body of the appliance has a constant L in the longitudinal direction.

[0061] To ensure that the overall detection range of home appliances is greater than or equal to 150° and less than 180°, the following must be met:

[0062] (Equation 5);

[0063] ;

[0064] .

[0065] Therefore, it can be concluded that , , According to the rules, 100°≤w<175°, therefore the range of values ​​for w is [max(120°-2N, 100°), 180°-2N).

[0066] The embodiments of the present disclosure provide a household appliance, comprising: a household appliance body; at least two detection devices mounted on the household appliance body, at least one of the at least two detection devices has an inclination angle N relative to a reference surface, and the N is in a range of (0°, 90°).

[0067] Specifically, since the at least two detection devices can be independently arranged, any one of them can be arranged in a horizontal direction, and then the N can be 0 at the minimum. In addition, considering that the two detection devices are arranged perpendicularly to the household appliance, the two detection devices can only detect the ranges on the left and right sides respectively, and then the N can be 90° at the maximum.

[0068] In combination with Figure 1 and Figure 2 , the design of the household appliance described above is further described below, and the derivation process of the range of the N is given.

[0069] The present disclosure provides a household appliance, comprising: a household appliance body; at least two detection devices mounted on the household appliance body, at least one of the at least two detection devices has an inclination angle N relative to a reference surface.

[0070] In some embodiments, as shown in Figure 1 , the N of any one of the at least two detection devices satisfies the following formula, which can make the overall detection range of the household appliance not less than 180°:

[0071] ; (Formula 1-1)

[0072] ; (Formula 1-2)

[0073] ; (Formula 1-3)

[0074] wherein, the N is in a range of (2.5°, 87.5°).

[0075] Specifically, in order to satisfy the 180° detection, the minimum deflection angle of the N satisfies (Formula 1-1), 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 1-3) needs to be satisfied, and the preset angle w can be at least one value in a range of [100°, 175°). From the above formula, it can be obtained that: when the w is 100°, the N is in a range of 40°≤N<50°, when the w is 175°, the N is in a range of 2.5°<N<87.5°, and thus, when the w is in a range of [100°, 175°], the N satisfies 2.5°<N<87.5°. when the w is in a range of [100°, 175°], the N satisfies 2.5°<N<87.5°.

[0076] In some embodiments, a preset detection angle of a single detection device can be selected based on the value of w, or a horizontal detection angle of a single detection device can be selected based on the value of w, or w can represent the horizontal detection angle of a single detection device.

[0077] In some embodiments, such as Figure 2 As shown, if N in at least two detection devices satisfies the following formula, the overall detection range of the household appliance can be greater than or equal to 150° and less than 180°:

[0078] (Equation 2-1)

[0079] (Equation 2-2)

[0080] (Equation 2-3)

[0081] (Equation 2-4)

[0082] in, N is at least one value in [100°, 175°), and the range of N is (2.5°, 40°).

[0083] Specifically, to satisfy 180° detection, the minimum deflection angle of N satisfies (Equation 2-1) and (Equation 2-2). To ensure the overlapping and intersecting detection areas of the two radars and avoid an infinitely large blind zone, (Equation 2-3) and (Equation 2-4) must be satisfied. The preset angle w can be at least one value from [100°, 175°). From the above equations, we can derive: When w is 100°, the range of N is 0° ≤ N < 40°; when w is 175°, the range of N is 0° < N ≤ 2.5°. Therefore, in When N is [100°, 175°), N satisfies 0°<N≤40°.

[0084] In this embodiment, at least two detection devices can be symmetrically arranged on the home appliance. In other words, the tilt angle N of at least two detection devices can be the same. For example, at least two detection devices are symmetrically arranged at the left and right ends of the home appliance. For example, two detection devices are respectively arranged in an outward octagonal symmetrical arrangement at the left and right ends of the home appliance. For example, the detection surfaces of at least two detection devices are arranged facing away from each other. "Arranged facing away from each other" can be understood as the emission directions of the two detection devices forming an obtuse angle, or the surfaces of the two detection devices equipped with transmitting antennas being arranged facing away from each other.

[0085] The value of N is an absolute value of an angle. For the value of N, the detection device arranged on the left is positive when rotating clockwise and negative when rotating counterclockwise; the detection device arranged on the right is negative when rotating clockwise and positive when rotating counterclockwise. For example, -10° can be a case that the left radar rotates counterclockwise by 10° or the right radar rotates clockwise by 10°.

[0086] In some embodiments, as shown in FIG. 1, N of 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°: Figure 2

[0087] ; (Formula 3-1)

[0088] ; (Formula 3-2)

[0089] ; (Formula 3-3)

[0090] ; (Formula 3-4)

[0091] wherein, N is at least one value in [102°, 140°], and the value of N is in the range of [5°, 31.5°].

[0092] Specifically, in order to realize a detection area between [150°, 180°), according to the above formula (Formula 1), L is taken as 1.5, and N needs to satisfy: , and according to the above (Formula 3-1), (Formula 3-2), , and d satisfies 0.1 meters≤d meters≤1.5 meters, so it can be concluded that , Therefore, w≥102°. When w is 102°, the value of N is 24°; when w is 140°, the value of N is 5°≤N≤20°; when w is 120°, the value of N is 15°≤N≤30°; when w is 117°, the value of N is 16.5°≤N≤31.5°. In summary, when w is at least one value in [102°, 140°], N satisfies [5°, 31.5°].

[0093] ​In this embodiment, at least two detection devices can be symmetrically arranged on the home appliance. In other words, the tilt angle N of at least two detection devices can be the same. For example, at least two detection devices are symmetrically arranged at the left and right ends of the home appliance. For example, two detection devices are respectively arranged in an outward octagonal symmetrical arrangement at the left and right ends of the home appliance. For example, the detection surfaces of at least two detection devices are arranged facing away from each other. "Arranged facing away from each other" can be understood as the emission directions of the two detection devices forming an obtuse angle, or the surfaces of the two detection devices equipped with transmitting antennas being arranged facing away from each other.

[0094] The value of N mentioned above is the absolute value of the angle. For the value of N, clockwise rotation of the detection device on the left is positive and counterclockwise rotation is negative; clockwise rotation of the detection device on the right is negative and counterclockwise rotation is positive. For example, -10° could be the case where the left radar rotates 10° counterclockwise or the right radar rotates 10° clockwise.

[0095] In some embodiments, such as Figure 2 As shown, if N in at least two detection devices satisfies the following formula, the overall detection range of the household appliance can be greater than or equal to 150° and less than 180°:

[0096] (Equation 4-1)

[0097] (Equation 4-2)

[0098] (Equation 4-3)

[0099] (Equation 4-4)

[0100] in, It is at least one value in [100°, 140°], and the value of N is in the range of [5°, 40°].

[0101] Specifically, to ensure the detection range is greater than or equal to 150° and less than 180°, the minimum tilt angle of N must satisfy (Equation 4-1) and (Equation 4-2). To ensure the detection areas overlap and prevent an infinitely large blind zone, N must satisfy (Equation 4-3) and (Equation 4-4). Given at least one value from [100°, 140°], the above formula can be used to derive: , When w is 100°, the range of N is 25° ≤ N ≤ 40°; when w is 140°, the range of N is 5° < N < 20°; and when w is 120°, the range of N is 15° ≤ N ≤ 30°. Therefore, in When N is [100°, 140°], N satisfies 5°≤N≤40°.

[0102] In the embodiment, the at least two detection devices can be symmetrically arranged on the household appliance. In other words, the tilt angles N of the at least two detection devices can be the same. For example, the at least two detection devices are symmetrically arranged at the left and right ends of the household appliance. For example, the two detection devices are symmetrically arranged at the left and right ends of the household appliance in an outer eight arrangement. For example, the detection surfaces of the at least two detection devices are arranged in a back-to-back manner. The "back-to-back arrangement" can be understood as that the emission directions of the two detection devices form an obtuse angle, or the surfaces on which the emission antennas of the two detection devices are arranged are arranged in a back-to-back manner.

[0103] The value of N described above is the absolute value of the angle. For the value of N, the detection device arranged on the left is positive when rotated clockwise and negative when rotated counterclockwise; the detection device arranged on the right is negative when rotated clockwise and positive when rotated counterclockwise. For example, -10° can be the case that the left radar is rotated counterclockwise by 10°, or the right radar is rotated clockwise by 10°.

[0104] In the above embodiment, the constant is any value in [100°, 175°). Alternatively, w is a preset detection angle, the preset detection angle of a single detection device can be selected according to the value of w, or the horizontal detection angle of a single detection device can be selected according to the value of w, or w can represent the horizontal detection angle of a single detection device.

[0105] In the above embodiment, w is any value in [100°, 140°]. w can be the detection range of a millimeter wave radar, for example Figure 1 and Figure 2 the horizontal detection range. In summary, in order to ensure that the detection range of the household appliance is as large as possible and the blind area is as small as possible, and to maximize the detection function effect, the value range of the tilt angle N of at least one of the at least two detection devices mounted on the main body of the household appliance needs to meet the range of (0°, 90°).

[0106] In some embodiments, the value range of N is (2.5°, 60°). When the value range of N is between 2.5° and 60°, the at least two detection devices can have different orientations, so as to be able to detect object information in different areas of the room, and the detection dead angle is small.

[0107] In some embodiments, the value range of N is (30°, 40°). When the value range of N is between 30° and 40°, 180° full-range detection can be achieved.

[0108] In some embodiments, the value of N is 35°. When w is 120°, in order to achieve 180° full-range detection, N is 35°, so that there are 5° margins on the left and right sides.

[0109] In the above embodiments, the home appliance main body can be any one of the following: a ducted air conditioner, a cabinet air conditioner, a central air conditioner, a mobile air conditioner, and a wall-mounted air conditioner.

[0110] In some embodiments, the at least two detection devices are millimeter wave radars.

[0111] In some embodiments, the frequencies of the at least two detection devices are within a preset range or the same.

[0112] In some embodiments, the preset range can be 24 GHz~24.25 GHz.

[0113] In some embodiments, the frequency of the millimeter wave radar can also be 24 GHz~77 GHz, specifically, 24 GHz, 60 GHz, and 77 GHz.

[0114] In some embodiments, the frequencies or frequency bands of the at least two detection devices are different.

[0115] In some embodiments, the tilt angles N of the at least two detection devices are different.

[0116] In some embodiments, the tilt angles N of the at least two detection devices are the same.

[0117] In other words, the tilt angle N of each detection device relative to the mounting plate can be the same or different. The "symmetrical arrangement" can be understood as the tilt installation angle N of the two detection devices being the same, and the "asymmetrical arrangement" can be understood as the tilt installation angle N of the two detection devices being different. For example, since the maximum angle of a single detection device is limited and cannot achieve 180° or more or [150°, 180°) coverage, at least two detection devices are needed to achieve wide-area detection. The maximum horizontal detection angle of a single detection device is between 90° and 180°, or for example, between 100° and 180°. In order to achieve wide-area detection, the two detection devices need to be deflected by a certain angle to the left and right. In order to minimize the blind area, the left and right deflection angles can be equal to N, but if the left and right detection devices have different deflection angle values, i.e., N1≠N2, the tilt angles N of the two detection devices still satisfy the above-described relationship between N and w.

[0118] In some embodiments, the home appliance is an air conditioner, and the air conditioner includes an air conditioner panel, and the detection device is installed on the air conditioner panel.

[0119] In some embodiments, the home appliance is a detection assembly suitable for being installed on a household appliance, and the home appliance main body is a mounting shell. For example, Figure 4As shown, the household appliance is a detection assembly suitable for being installed on a household appliance, wherein the household appliance body (101) is a mounting shell. The detection device (102) is installed in the mounting shell. At this time, the household appliance can be used to detect target objects around (for example, in front of) the household appliance. The target objects can be static objects or dynamic objects, and the dynamic objects can be machine devices or animals / humans.

[0120] For example, at least two detection devices are assembled on the household appliance, and the household appliance can be directly installed on the household appliance.

[0121] In the above embodiment, the range of L can be L < 1.5 or L < 1.2 or L < 1 or L < 0.8 or L < 0.5 or L < 0.2, and according to different ranges of L, the corresponding ranges of d can be obtained respectively, so that the overall detection range of the household appliance is larger, and the functional effect of the at least two detection devices is maximized.

[0122] In some embodiments, the at least two detection devices have a mounting interval d meters, and d is at least 0.1.

[0123] In the present disclosure, the value range of d can be [0.1, D], and D is any one of the length value of the air conditioner device, the length value of the air duct machine of the air conditioner device, or the length value of the air guide panel of the air conditioner device. For example, D is 3. Alternatively, D is 1.46. In some embodiments, the maximum value of D is the maximum value of the length of the air conditioner device or the maximum value of the length of the air duct machine of the air conditioner device or the maximum value of the length of the air guide panel of the air conditioner device. Therefore, by restricting the interval d to be not less than 0.1, it can be avoided that the interference value or the detection accuracy is affected when the two detection devices with the same frequency detect at the same time; by limiting d to be less than 3 or 1.46, and d and N satisfying the above described relationship, the detection range of the household appliance can be larger under the condition that the interference of the two detection devices with the same frequency is small.

[0124] In combination with the above embodiment, in some embodiments, the mounting angle of each detection device in the vertical direction can be designed.

[0125] As shown in the schematic diagram of Figure 5 and 6 The detection device has a first mounting angle a, which is the included angle between the main plane of the detection device and the first reference line. The first reference line can be a vertical line.

[0126] In some embodiments, the mounting angle is related to the installation height of the household appliance.

[0127] For example, as shown in the schematic diagram of Figure 6 The included angle between the main plane of any one detection device and the vertical line is The installation height of the home appliance is H meters, the maximum detection distance that a single detection device can achieve is S meters, and the area where the home appliance is installed is S1 meters.

[0128] exist Figure 6 In this context, the constant Q is related to the constant w'. For example, the maximum normal detection distance of the detection device can be determined based on the constant Q. The maximum detection distance is defined as follows: when the distance between the intersection of Q and S and the ground is exactly equal to h, then... The optimal angle, at which the detection device can detect a person in front of the appliance, when... As the number of people decreases further, the detection device can no longer detect them; therefore, at this point... The minimum value.

[0129] exist Figure 6 In this context, the constant L can be a preset value, and the longitudinal detection blind zone of the detection device can be determined based on the value of the constant L.

[0130] In some embodiments, The constraint relationship formed by L and S determines that the constraints of L and S are related to H and S1, and as... As L increases, L will decrease. When L is 0, L is at its maximum. As L increases, its limit becomes 0; when As L decreases, the value of L will increase, and the value of S will also increase accordingly.

[0131] Figure 6 The w' shown is a constant (in degrees) within a preset range. It should be understood that... Figure 1 or Figure 2 The constant w shown is Figure 6 The values ​​or ranges of w' shown are different.

[0132] In some embodiments, it may be based on Figure 6 In the corresponding embodiment, the value of 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.

[0133] In some embodiments, the first installation angle [1.4°, 90°].

[0134] In some embodiments, the first installation angle Satisfy the following formula: , where w' is at least one value in [50°, 90°].

[0135] In some embodiments, A can be a constant (in meters), and the maximum value of A is 2 meters.

[0136] In some embodiments, A = H-h, where H can be in the range of [2, 3], and h can be in the range of [1, 2].

[0137] In some embodiments, the constant L can be less than 1.5 meters or 1.2 meters. The maximum value of L can be the same or different for different household appliance bodies. For example, for a ducted air conditioner, L should be less than 1.5 meters or 1.2 meters; for a ceiling-mounted air conditioner, L should be less than 1 meter or 0.8 meters; for a cabinet air conditioner, L should be less than 0.5 meters; and for a mobile air conditioner, L should be less than 0.2 meters.

[0138] In some embodiments, the first installation angle is in the range of [1.4°, 60°].

[0139] In some embodiments, the first installation angle is in the range of [10°, 60°].

[0140] In some embodiments, the first installation angle is in the range of [10°, 45°].

[0141] In some embodiments, the first installation angle is 10° or 30°.

[0142] In some embodiments, the first installation angle satisfies the following formula in relation to the minimum blowing angle b of the upper and lower air guide plates: wherein b is at least one value in the range of [50°, 90°], w’ is the radar vertical detection angle, or w’ is at least one value in the range of [60°, 90°].

[0143] In some embodiments, b is in the range of [15°, 50°].

[0144] In some embodiments, the household appliance body is a cabinet air conditioner, A = H-1, and H is the distance from the detection device to the bottom of the cabinet.

[0145] For example, as shown in the schematic diagram of Figure 5 , when determining the vertical direction blind area distance, the minimum angle of the upper and lower air guide plates of the household appliance (such as an air conditioner) is evaluated to ensure that the detection area of the detection device covers the area blown by the household appliance, i.e., L≤L1, and therefore the relationship between the vertical inclination angle of the detection device and the minimum angle b of the upper and lower air guide plates can be .

[0146] In some embodiments, Wherein, H is the installation height of the household appliance, h is the height of the user, b is the minimum angle of the up and down air deflector, and L1 is related to b.

[0147] In some embodiments, when the horizontal detection angle w' of the at least two detection devices is 120°, in order to make the overall detection range greater than 180°, the inclination angle N is 35°, the first installation angle is 10°, d>0.1, and L is about 1.2 meters.

[0148] For example, , 2≤H≤3, h≤1.8, S≤8 can be achieved, so when H=2, h=1.8, the farthest detection distance S of a single radar is 8, The minimum value is , that is °. As Figure 6 shown in the schematic diagram, the maximum value of is 90°, so can be greater than or equal to 1.4° and less than or equal to 90°, and in this range, the functional effect of the detection device can be maximized.

[0149] In some embodiments, the number of detection devices on the household appliance can be one, two or more, and the present disclosure does not limit this.

[0150] In summary, the present disclosure has the following technical effects:

[0151] 1. Since a single detection device cannot achieve 180° or more coverage, multiple detection devices are needed to achieve 180° or more detection of the household appliance, and the horizontal inclination installation angle N of a single detection device is within (2.5°, 87.5°), thereby achieving 180° or more detection of the household appliance.

[0152] 2. In order to make the overall detection range of the household appliance in [150°, 180°), when the at least two detection devices are symmetrically installed, the horizontal inclination installation angle N of a single detection device can be within the value range of (0°, 40°], [5°, 31.5°], [5°, 40°].

[0153] 3. In order to make the overall detection range of the household appliance in [150°, 180°), when the at least two detection devices are asymmetrically installed, the horizontal inclination installation angle N of a single detection device can be within the value range of (0°, 40°], [0°, 31.5°].

[0154] 4. According to different product types, under different values of the constant L, the relationship between the installation interval d between the at least two detection devices and the respective horizontal inclination installation angle N can be obtained, thereby optimizing the arrangement of the detection devices of the household appliance.

[0155] 5. When two detection devices with the same frequency are selected for arrangement, since there is interference between the detection devices with the same frequency, in order to avoid interference values ​​or affecting the detection accuracy when the detection devices with the same frequency are detected at the same time, the horizontal spacing d should not be less than 0.1 when the detection devices are arranged on the left and right, so as to achieve an overall detection range of 180° or more while avoiding interference between devices with the same frequency.

[0156] 6. By designing the first installation angle α in the vertical direction, the detection range of the detection device in the vertical direction was optimized.

[0157] In summary, by constructing parameters for at least two detection devices on home appliances and the correlation between these parameters, it is possible to quickly calculate the reasonable distribution of these devices when installing dual detection devices on home appliances (such as air conditioners). This enables the implementation of dual-radar horizontal detection (150°, 180°) or ultra-wide-area detection of 180° and above. The horizontal deflection angles of the left and right dual radars are reasonably standardized, and the layout is optimized by comprehensively considering factors such as the maximum horizontal detection angle, the minimum blind zone, and the minimum interference.
