[0027] 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.

[0028] In embodiments of this disclosure, a detection device can be installed on the home appliance to detect dynamic objects or people in the area in front of the appliance. In embodiments of this disclosure, the type of home appliance is not limited; it can be any home appliance.

[0029] This disclosure proposes a household appliance, comprising: a main body of the household appliance; and a detection device installed on the main body of the household appliance, the detection device having a first installation angle α.

[0030] The first installation angle α can be determined by the constraint relationship formed by L and S. L can be a constant, and the longitudinal detection blind zone of the detection device can be determined based on the value of the constant L.

[0031] In some embodiments, the first installation angle may be an acute angle, and the first installation angle may be related to the installation height of the appliance or the size of the area where the appliance is installed. In other words, the first installation angle can be adjusted according to the installation height of the appliance and / or the size of the area where the appliance is installed.

[0032] For example, such as Figure 1 The schematic diagram shows that the angle between the main plane of the detection device and the vertical line is 'a', the installation height of the appliance is H, the size of the area where the appliance is installed is S1, and the vertical blind zone distance is L. 'a' is adjustable, and its adjustment range is determined by the constraint relationship formed by L and S. The constraint between L and S is related to H and S1. As 'a' increases, L decreases. When 'a' is 0°, L is at its maximum. As 'a' continues to increase, the limit value of L is 0. As 'a' continues to decrease, the value of L increases, and the corresponding value of S also increases. When the distance between the intersection of Q and S and the ground is exactly equal to 'h', this is the optimal angle for 'a'. At this point, the detection device can detect people in the area in front of the appliance. When 'a' continues to decrease, the detection device cannot detect people; therefore, this is the minimum value of 'a'.

[0033] The first installation angle α satisfies the following formula: Specifically, A is a constant, and A takes at least one value from [0, 2]. The maximum value of A is 2.

[0034] In some embodiments, A = Hh, where H can be in the range of [2,3] and h can be in the range of [1,2].

[0035] In some embodiments, L is a constant, and the value of L can be less than 1.5 or 1.2. The maximum value of L can be the same or different for different main components of the household appliance.

[0036] In some embodiments, the first installation angle α satisfies the following formula: Where w is at least one value in [50°, 90°], and A is at least one value in [0, 2]. For example, as shown... Figure 1 As shown, 'a' is the vertical tilt angle of the detection device, 'H' meters is the installation height of the detection device from the ground or the installation height of the household appliance, 'h' meters is the height of the target being detected, and 'w' represents the vertical detection angle of a single detection device. 'a', 'H', and 'h' satisfy the following formula: L is less than 1.5, H-1 = A, A = 2.

[0037] In the above embodiments, the range of the detection blind zone is reduced by limiting the relationship between the first installation angle and H and h to satisfy the above inequality.

[0038] In some embodiments, the first installation angle α satisfies the following formula: Where w is at least one value in [50°, 90°], A is at least one value in [0, 2], and the maximum value of A is 2.

[0039] For example, such as Figure 1 As shown, 'a' is the vertical tilt angle of the detection device, 'H' meters is the installation height of the household appliance, 'h' meters is the height of the target being detected, and 'w' is the vertical detection angle of a single detection device. 'a', 'H', and 'h' satisfy the following formula: L is less than 1.2, H-1 = A, A = 2.

[0040] In the above embodiments, by limiting the relationship between the first installation angle and H and h to satisfy the above inequality, the detection blind zone is smaller when L is less than 1.2 compared to when L is less than 1.5.

[0041] For example, If 2 ≤ H ≤ 3 and h ≤ 1.8, then S ≤ 8 can be achieved. Therefore, when H = 2, h = 1.8, and S = 8, a takes its minimum value. That is, a ≥ 1.4°. For example... Figure 2 As shown in the schematic diagram, the maximum angle of 'a' is 90°. Therefore, we can conclude that 'a' 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.

[0042] In some embodiments, for different values ​​of constants w and A, the upper and lower limits of a under different conditions can be obtained according to the above inequality, so as to achieve the effect of this disclosure under different w conditions, within the satisfied range.

[0043] In some embodiments, the adjustment range of the first installation angle α is [1.4°, 60°].

[0044] In some embodiments, the adjustment range of the first installation angle α is [10°, 60°].

[0045] In some embodiments, the adjustment range of the first installation angle α is [10°, 45°].

[0046] In some embodiments, the adjustment range of the first installation angle α is [15°, 45°].

[0047] In some embodiments, the first installation angle α is 10°.

[0048] In some embodiments, it may be based on Figure 1 In the corresponding embodiment, the value of the constant w is selected as the preset detection angle of a single detection device, or the value of w can be used to select the vertical detection angle of a single detection device, or w can represent the vertical detection angle of a single detection device.

[0049] In some embodiments, provided that the detection distance meets the basic requirements for room detection, when w is 60° and a is 10°, the maximum distance and blind zone range can be balanced to maximize the functional effect.

[0050] In some embodiments, when a is 10°, a larger detection range can be used, such as a detection device with w = 90°, to meet the requirement of a larger detection area and a smaller blind zone compared to a detection area with w = 60°.

[0051] In some embodiments, the first installation angle α is 30°.

[0052] For example, Where H meters is the installation height of the home appliance, h meters is the user's height, w is a constant, a is the first installation angle, and L is a constant.

[0053] In some embodiments, a preset detection angle of a single detection device can be selected based on the value of w, or a vertical detection angle of a single detection device can be selected based on the value of w, or w can represent the vertical detection angle of a single detection device.

[0054] In some embodiments, the longitudinal detection blind zone of the detection device can be determined based on the value of a constant L. The longitudinal detection blind zone of the detection device can be the vertical distance between the nearest critical position where the detection device can detect the user and the projection of the appliance on the horizontal plane.

[0055] In some embodiments, w can be the vertical detection angle of the detection device. The value range of w can be 50°≤w≤90° or 60°≤w≤90°. This disclosure does not limit this range. The value of w can also be determined with reference to the actual situation of the detection device in the household appliance.

[0056] In some embodiments, the first installation angle a and the minimum air delivery angle b of the upper and lower air guide plates satisfy the following formula: 90°-w / 2-a≤b, where the constant w is at least one value in [50°, 90°].

[0057] In some embodiments, the value of b ranges from [15°, 50°].

[0058] In some embodiments, w is any value in [50°, 90°].

[0059] In some embodiments, w is at least one value from [60°, 90°].

[0060] In some embodiments, w is any value in [60°, 90°].

[0061] In some embodiments, the home appliance is a cabinet unit, where A = H-1, and H meters is the distance from the detection device to the bottom of the cabinet unit.

[0062] In some embodiments, the value of b can be obtained from actual experimental measurements.

[0063] In some embodiments, the value of b can be obtained based on the actual installation of the air guide component in the home appliance, and this disclosure does not limit it.

[0064] In some embodiments, taking the heating mode as an example, b can be the angle when adjusted to the minimum setting.

[0065] For example, such as Figure 2 In the schematic diagram shown, the first length L can be the vertical blind zone distance. When determining the vertical blind zone distance, it is evaluated in conjunction with the minimum angle of the upper and lower air guide plates of the air conditioner to ensure that the vertical detection area of ​​the detection device covers the area blown by the air conditioner, i.e., L≤L1. Therefore, the relationship between a and the minimum angle b of the upper and lower air guide plates can be...

[0066]

[0067] In some embodiments, L1 = (Hh) × tan b, where H meters is the installation height of the home appliance, h meters is the user's height, b is the minimum angle of the upper and lower air guides, and L1 is related to b.

[0068] In some embodiments, a change in the first installation angle will cause a change in L; as 'a' increases, L decreases. To prevent missed detection of targets in front of the appliance, the blind zone should be as small as possible, i.e., L should be as small as possible.

[0069] In some embodiments, the detection device may be a millimeter-wave radar, and the first installation angle may be the angle between the main plane of the millimeter-wave radar and the vertical line, i.e., the vertical tilt angle of the radar.

[0070] In some embodiments, the frequency band of the millimeter-wave radar is 24 GHz to 24.25 GHz, and for example, it can also be 24 GHz, 60 GHz, and 77 GHz.

[0071] In some examples, when the main body of the home appliance is a ducted air conditioner or a wall-mounted air conditioner, the mounting plate is the air conditioner panel, and the detection device is installed on the air conditioner panel.

[0072] In some embodiments, the number of detection devices on the household appliance may be one or two, and this disclosure does not limit this.

[0073] In some embodiments, when there are two detection devices on a home appliance, in order to maximize the functional effect of the detection devices, it is necessary to determine the installation distance d meters between the two detection devices.

[0074] In some embodiments, when at least two detection devices are installed on a home appliance for human detection, the spacing between the at least two detection devices needs to be designed so that the overall detection range of the home appliance is larger, for example, reaching a wide-area detection range of more than 180°.

[0075] In some embodiments, the lateral distance (installation interval) between any two detection devices is d meters, where d is greater than zero.

[0076] For example, such as Figure 3 As shown, when the maximum horizontal detection angle w' of a single detection device and the left-right tilt angle N of a single detection device are fixed, the smaller the lateral spacing d, the smaller the maximum vertical blind zone distance L, and the smaller the blind zone; conversely, the larger the lateral spacing d, the larger the maximum vertical blind zone distance L, and the larger the blind zone. It should be understood that... Figure 1 The 'w' shown represents the vertical detection angle. Figure 3 The w' shown represents the horizontal detection angle, and the range of values ​​for the horizontal detection angle and the vertical detection angle are different.

[0077] In some embodiments, according toFigure 3 The diagram shown, and the relationship between L and d: The minimum value of L is the distance corresponding to the minimum value of d. When L (meters) is greater than 0.5 meters, there are cases where it cannot be detected. Therefore, the minimum value of L (meters) can be 0.5 meters, that is, the range of L can be L ≤ 0.5 meters.

[0078] In some embodiments, the value of d can be determined based on the type and parameters of the home appliance. In one example, if the main body of the home appliance is a ducted air conditioner with a power of 1.5 horsepower, then the value of d ranges from [0.1, 0.8]. In another example, if the main body of the home appliance is a cabinet air conditioner, then the value of d ranges from [0.1, 0.3] or [0.1, 0.5].

[0079] In some embodiments, the value of d can be in the range of [0.1, 3], where 3 is the maximum value of the length of the air conditioning equipment, or the maximum value of the length of the air duct of the air conditioning equipment, or the maximum value of the length of the air guide panel of the air conditioning equipment.

[0080] In some embodiments, w' is a preset detection angle, such as the horizontal preset detection angle of the detection device. The value of w' can be referred to the value range in the embodiments shown in the single detection device above, and will not be repeated here.

[0081] In some embodiments, when at least two detection devices are installed on a home appliance, in order to achieve a larger overall detection range, it is necessary not only to design the installation interval, but also to design the range of values ​​for the tilt angle N of at least one detection device relative to the reference surface.

[0082] In some embodiments, when the maximum horizontal detection angle w' of a single detection device decreases, the left and right tilt angles N must be increased accordingly to meet the requirement of 180° full-area detection coverage. In this case, in order to keep the maximum vertical blind zone distance L unchanged, the lateral spacing d needs to be reduced.

[0083] In some embodiments, such as Figure 3 As shown, N in at least two detection devices must satisfy the following formula to ensure that the overall detection range of the household appliance is not less than 180°:

[0084]

[0085] Where w' is at least one value in [100°, 180°), and N has a value range of (2.5°, 87.5°).

[0086] Specifically, w is the horizontal measurement angle, calculated according to the following formulas: w'≥180°-2N, w'<180°+2N, w'≥2N; the blind area distance size satisfies From the above formula Wherein, L<1m, then According to the regulation, the constant w' satisfies 100°<w'<180°, therefore, max(180°-2N, 2N, 100°)<w'<180°, and 2.5°<N<87.5°, therefore, the angle N of the two detection devices and the distance d need to satisfy When 2.5°<N<87.5°, d>0, the above formula is established.

[0087] In some embodiments, as shown in Figure 4 The N in the at least two detection devices satisfies the following formula, which can make the overall detection range of the home appliance device greater than or equal to 150° and less than 180°:

[0088]

[0089] In the case that the w is measured to be at least one value in [100°, 175°), the value range of N is (0°, 40°].

[0090] In some embodiments, as shown in Figure 4 When the at least two detection devices are symmetrically arranged at the left and right ends of the home appliance device, the N satisfies the following formula, which can make the overall detection range of the home appliance device greater than or equal to 150° and less than 180°: Wherein, the constant w' is any value in [102°, 140°], and the value range of N is [5°, 31.5°].

[0091] In some embodiments, as shown in Figure 4 When the at least two detection devices are symmetrically arranged at the left and right ends of the home appliance device, the N satisfies the following formula, which can make the overall detection range of the home appliance device greater than 150° and less than 180°: Wherein, the constant w' is at least one value in [100°, 140°], and the value range of N is [5°, 40°].

[0092] In some embodiments, as shown in Figure 4 When the at least two detection devices are asymmetrically arranged at the left and right ends of the home appliance device, the N satisfies the following formula, which can make the overall detection range of the home appliance device greater than or equal to 150° and less than 180°: Wherein, the constant w' is at least one value in [100°, 175°], and the value range of N is (0°, 40°].

[0093] In some embodiments, asFigure 4 As shown, when at least two detection devices are asymmetrically arranged at the left and right ends of the home appliance, N can make the overall detection range of the home appliance greater than or equal to 150° and less than 180° when the following formula is satisfied: Where w is at least one value in [100°, 140°], and N ranges from (0°, 31.5°).

[0094] In the above embodiments, at least two detection devices are arranged back-to-back. Here, "back-to-back arrangement" can be understood as the emission directions of the two detection devices forming an obtuse angle, or the backs of the two detection devices equipped with transmitting antennas being arranged back-to-back.

[0095] Therefore, in summary, when at least two detection devices are installed on a household appliance, the tilt angle N of at least one of the at least two detection devices relative to the reference surface can be in the range of (0°, 90°).

[0096] The following are specific implementation methods of the household appliances provided in this disclosure:

[0097] like Figure 1 The diagram shows the vertical tilt angle of the detection device. The installation height of the household appliance is H meters, the vertical tilt angle of the detection device is a, the vertical detection angle of the detection device is w, the maximum normal detection distance of the detection device is Q meters, the maximum detection distance that the detection device can achieve is S meters, the height of the detection target is h meters, and the vertical blind zone distance is L meters.

[0098] Regarding the reasonable arrangement of the detection device on household appliances, the correlation between various parameters is as follows:

[0099]

[0100] S = Q × sin(90° - a) (Equation 2)

[0101] 1. A change in the vertical tilt angle 'a' of the detection device will cause a change in the vertical blind zone distance 'L' and the maximum detection distance 'S' that the detection device can achieve. As 'a' increases, both 'S' and 'L' decrease.

[0102] 2. To prevent missed detection of targets in front of home appliances, the blind zone should be as small as possible, that is, the vertical blind zone distance L should be as small as possible; to achieve a larger human detection area, the maximum detection distance should be as large as possible, that is, the farthest detection distance S that the detection device can achieve should be as large as possible.

[0103] 3、When the height H of the household appliance, the height h of the detection target, the vertical inclination angle a of the detection device, the longitudinal detection angle w of the detection device and the farthest normal detection distance Q of the detection device itself are known, the vertical blind area distance L and the farthest detection distance S that can be achieved by the detection device can be calculated by formula 1 and formula 2 respectively.

[0104] 4、The detection distance of the detection device along the normal direction of itself is the farthest, and the detection distance attenuates as the angle to both sides expands. Therefore, when the vertical inclination angle a is increased, the blind area is realized to be smaller, and the vertical blind area distance L is reduced, and at the same time, the actual farthest detection distance of the detection device is sacrificed. Therefore, under the condition that other parameters are known, the optimal vertical inclination angle a is found by balancing the minimum blind area and the farthest detection distance through formula 1 and formula 2.

[0105] 5、When determining the vertical blind area distance L, the minimum angle of the up and down air guide plate of the household appliance can be combined for evaluation, as shown in the minimum angle diagram of the up and down air guide plate of the air conditioner. Figure 2 The detection area of the household appliance is ensured to cover the area that can be blown by the air conditioner, and L1 is the nearest distance to ensure that the air can be blown, that is, L≤L1.

[0106] In summary, considering the installation height of the household appliance and the vertical detection range of the detection device, in order to realize the minimum blind area in front of the household appliance and the farthest actual detection distance, the relationship formula of the vertical blind area distance L and the farthest detection distance S that can be achieved by the detection device is constructed, the optimal vertical inclination angle a is obtained by balancing the blind area and the farthest detection distance, and thus the installation mode of the detection device on the household appliance is provided, so that the functional effect is maximized.
