[0052] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0053] In addition, in the present invention, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0054] The invention provides an electric control box.

[0055] Reference Figure 1 and Figure 2 In one embodiment, the electric control box comprises:

[0056] The first housing 010 comprises a first air duct 011 and a second housing 012, wherein a first air inlet of the first air duct 011 and a second air inlet of the first air duct 011 are respectively arranged on different side walls of the first housing 010, and the second housing 012 is at least partially connected to the first air duct 011;

[0057] A second accommodating cavity is provided in the second housing 012, and the second accommodating cavity is used to accommodate the control board;

[0058] A first switch group 020, including a first switch and a second switch, wherein the first switch can be opened and closed and is arranged at the first air inlet, and the second switch can be opened and closed and is arranged at the first air outlet;

[0059] When the first switch group controls the first air inlet and the first air outlet to be opened, the first air duct is used to exchange heat with the control board through the second shell.

[0060] For existing electric control boxes, the control board is directly loaded in a product shell. In order to be waterproof and dustproof, the product shell is set to be sealed. Some electric control boxes are provided with openable and closable vents for ventilation in order to dissipate heat. Therefore, when the existing electric control box dissipates heat, if there is a vent, the wind entering the vent will directly contact the control board, which will have strict requirements on the external water vapor and dust conditions. When the external environment does not meet the conditions, the vent of the electric control box will be completely closed to achieve sealing. However, in order to be strong and durable, the product shell is usually made thicker, which makes the heat exchange poor. When the vent is completely closed, the electric control box will not be able to continue to dissipate heat effectively.

[0061] In order to solve the above problem, in this embodiment, the materials and functions of the first shell 010 and the second shell 012 are different, wherein the first shell 010 is the product shell of the electric control box, and the second shell 012 is an internal protective shell for heat exchange.

[0062] Specifically, the thickness of the first shell 010 is greater than that of the second shell 012. The first shell 010 can be made of materials with high hardness such as steel and iron alloy, and the second shell 012 can be made of brass, stainless steel, copper alloy or other materials with high thermal conductivity.

[0063] When the electric control box dissipates heat from the control board, the first switch in the first switch group 020 is linked with the second switch group to open the first air inlet and the first air inlet. At this time, the first air duct 011 of the first shell 010 introduces air to cool the connected second shell 012. The second shell 012 can be partially connected to the first air duct 011, and the components of the control board are exchanged with cold air through at least one side, or it can be completely arranged in the first air duct 011, and the cold air received exchanges heat with the components through each side wall.

[0064] The technical solution of the present invention divides the original electric control box into two functional areas by setting the first air duct 011 and the second shell 012 in the first shell 010. The first air duct 011 introduces external wind and exchanges heat with the second shell 012 to achieve cooling of the components in the control board. At the same time, the second shell 012 is used to place the control board to achieve waterproof and dustproof of the control board. Therefore, when the electric control box of the present application opens the first switch group 020 for air cooling and heat dissipation, it does not need to make excessive requirements on the external water vapor and dust conditions, which improves the heat dissipation efficiency of the electric control box and can reduce the situation where the components of the electric control board are too high due to the airtightness of the electric control box, affecting the working performance of the whole machine.

[0065] Reference Figures 1 to 3In one embodiment, the second housing 012 further includes a second air inlet and a second air outlet, and the second air inlet and the second air outlet are connected to the first air duct 011;

[0066] The electric control box also includes:

[0067] The second switch group 030 includes a third switch and a fourth switch, wherein the third switch can be opened and closed and is set at the second air inlet, and the fourth switch can be opened and closed and is set at the second air inlet.

[0068] In this embodiment, a second air inlet and a second air outlet are provided on the side wall of the second shell 012, so that when the concentration of water vapor, dust, etc. outside is low, the second shell 012 can be ventilated by controlling the third switch and the fourth switch group in the second switch group 030 in linkage. The wind connected to the first air inlet can be partially used for heat exchange with the second shell 012 through the first air duct 011, and partially used for direct air cooling and heat dissipation of the internal control panel through the second air inlet. Under some conditions, such as when one side wall of the second shell 012 is attached to one side wall of the first shell 010 and the first air duct 011 is treated as a single air duct, the second switch group 030 can completely cut off the first air duct 011 by adjusting the opening, so that the wind connected to the first air inlet is all directly used for air cooling and heat dissipation of the control panel through the second air inlet.

[0069] Similarly, when the concentration of water vapor, dust, etc. outside is high, the second air inlet and the second air outlet are completely closed by controlling the third switch and the fourth switch group in the second switch group 030 in linkage, so that the second shell 012 becomes a waterproof and dustproof sealed shell, and heat exchange and cooling are performed only through the first air duct 011.

[0070] In order to further increase the heat dissipation efficiency of the electric control box when the external water vapor and dust conditions are poor, optionally, the electric control box further includes:

[0071] The filter module 040 is disposed in the first shell 010 and is attached to the first air outlet.

[0072] The filter module 040 can be a medium such as cotton or activated carbon. When the first switch group 020 is turned on and the wind is connected to the first air duct 011, the external wind is filtered through the filter module 040 to reduce environmental parameters such as water vapor and dust at the second air inlet, increase the probability of the second switch group 030 being turned on, and improve the heat dissipation efficiency of the electric control box when the external water vapor and dust conditions are poor.

[0073] Reference Figure 4 The present invention also provides a heat dissipation control method for an electric control box, which is applied to the above-mentioned electric control box, and the method comprises:

[0074] S100, controlling the first switch group to open or close the first air inlet and the first air outlet according to the current device temperature of the control board;

[0075] S200: When the first air inlet and the first air outlet are opened, the first switch group is controlled to adjust the air intake volume of the first air inlet according to a first environmental parameter at the first air inlet.

[0076] The heat generated inside the electric control box is mainly the heat generated by the operation of the components in the control board, and the temperature range in which the components can work normally is prioritized. Once the current device temperature exceeds its maximum heat-resistant temperature, the components will burn out, thereby affecting the normal control operation of the control board.

[0077] Therefore, in this embodiment, the heat dissipation of the electric control box is controlled based on the current device temperature of the control board. Specifically, a reference device temperature is set inside the control board, and the device temperature takes a redundant value according to the critical value of the normal working temperature range of the component. For example, when the normal working temperature range is -55°C to +125°C, the reference device temperature can be set to 90°C, 100°C, 110°C, etc. When the current device temperature is lower than the reference device temperature, it means that the components on the control board do not need heat dissipation at this time. Therefore, the control board controls the first switch group to close the first air inlet and the first air outlet to prevent external dust and moisture from entering the product housing (i.e., the first shell); and when the current device temperature reaches the reference device temperature, it means that the components on the control board are about to reach the critical value of the normal working temperature range, and cooling measures need to be taken immediately. Therefore, the control board controls the first switch group to open the first air inlet and the first air outlet, and heat is exchanged with the second shell through the first air duct to cool the components of the control board.

[0078] It should be noted that although in the above examples, the normal operating temperature range is set to -55°C to +125°C, in actual work, the actual tolerance temperature of components is often much higher than the normal operating temperature range, reaching between 125°C and 175°C. That is, when the temperature reaches 140°C, the components will still work, but the reliability will be reduced, and they will only be destroyed when the temperature exceeds the maximum heat resistance temperature, such as 200°C.

[0079] When the first air inlet and the first air outlet are opened, the components in the control board need to dissipate heat, but the first air inlet and the first air outlet cannot be fully opened in all cases to achieve the most efficient cooling. For example, if there is a lot of dust in the external air, it may cause the first air duct to be blocked, and if there is high humidity, it may cause water to enter the product shell (i.e., the first shell). In these cases, the air intake of the first air inlet needs to be controlled. Therefore, a detection module electrically connected to the control board is also provided at the first air inlet. The detection module is used to detect the first environmental parameters including particle size, humidity, etc., and output the detection results to the control board, and the control board adjusts the air intake of the first air inlet according to the first environmental parameters.

[0080] It should be noted that in order to obtain the current device temperature, Figure 8 As shown, a temperature detection module is arranged near the main heat generating components of the control board, and the circuit structure of the temperature detection module is as follows: Fig.12 As shown, a voltage divider circuit may include a first resistor R1 (a variable resistor whose resistance value changes with temperature) and a resistor R2, and the detection signal of the voltage divider circuit is a sampling voltage UR1'.

[0081] Specifically, the sampling voltage UR1'=I1*R1, wherein I1 is the current of R1.

[0082] like Fig.10 As shown, the control board is provided with an operational amplifier circuit and a first comparator, and the circuit structure of the first comparator is as follows: Fig.13 As shown, UR1 represents the signal after the sampling voltage UR1' is processed by the operational amplifier circuit, and the relationship between the two is UR1=K1*UR1', where K1 is the amplification factor of the operational amplifier circuit.

[0083] Furthermore, Uref1 is a voltage value representing the temperature of the reference device, and F1 is the output of the comparator 1. If UR1>Uref1, F1 is a low level L, otherwise it is a high level H.

[0084] When F1=L, the control panel preliminarily adjusts the opening of the first switch group according to the range of the threshold value, and sends a signal to shut down when F1=H.

[0085] Reference Figures 4 to 5 In one embodiment, controlling the first switch group to adjust the air volume of the first air inlet according to the first environmental parameter at the first air inlet includes:

[0086] S210, obtaining a first preset curve corresponding to the first environmental parameter, and determining a first target angle corresponding to the current first environmental parameter according to the first preset curve;

[0087] S220: Adjust the opening of the first switch group according to the first target angle.

[0088] In this embodiment, the first preset curve may be set to include at least one associated stage based on multiple experiments by R&D personnel.

[0089] Specifically, Fig.14 As shown, the first preset curve may include three associated stages, which are divided according to the value of the first environmental parameter, and may be a first linear function, an inverse proportional function and a second linear function from small to large.

[0090] Among them, the slope of the first linear function is the largest, the slope of the inverse proportional function gradually decreases as the value of the first environmental parameter increases, and the slope of the second linear function remains relatively large.

[0091] This is because, in the first association stage, since the opening of the first switch group is close to fully open at this time, only a slight deterioration in the environment will also enter the product casing (i.e., the first shell) and have an impact; in the second association stage, in order to balance the impact of the first environmental parameter on the internal space of the product casing and the heat dissipation requirements of the components in the control board, the change rate of the opening of the first switch group is changed in real time; in the third association stage, the first environmental parameter is too large, so it is necessary to reduce the opening of the first switch group in time, and when the first environmental parameter exceeds the preset reference environmental parameter, the first switch group is immediately closed.

[0092] Reference Figures 4 to 6 In one embodiment, the first environmental parameter includes a first environmental humidity and a first environmental granularity, and after obtaining the first preset curve corresponding to the first environmental parameter, the method further includes:

[0093] S211, determining a humidity change curve according to a first humidity detected within a preset period of time, and determining a particle size change curve according to a first environmental particle size detected within the preset period of time;

[0094] S212, determining the humidity of the next detection cycle according to the first environmental humidity of the current detection cycle and the humidity change curve, and determining the particle size of the next detection cycle according to the first environmental particle size of the current detection cycle and the particle size change curve;

[0095] S213, determining a first target angle of the next detection cycle according to a preset humidity-opening curve, a preset particle size-opening curve, the humidity of the next detection cycle, and the particle size of the next detection cycle.

[0096] In this embodiment, the control panel collects historical data of the first environment particle size and the first environment humidity within a preset period of time through sensors or monitoring equipment, and draws corresponding humidity change curves and particle size change curves. Then, according to the humidity change curve and the particle size change curve, analysis is performed to find the correlation between the first environment particle size and the first environment humidity. Specifically, statistical methods or machine learning algorithms can be used to analyze the data to determine the trends and patterns between them.

[0097] Based on the results of data analysis, a prediction model is established using methods such as regression models or time series models, and the first environmental humidity and the first environmental granularity of the current detection cycle are input to predict the first environmental granularity and the first environmental humidity of the next detection cycle. Thus, the predicted first environmental granularity and the first environmental humidity of the next detection cycle are respectively brought into the corresponding curves to jointly determine the first target angle of the next detection cycle, and when the next detection cycle arrives, the opening of the first switch group is adjusted according to the first target angle.

[0098] Through the above steps, the first target angle of the next detection cycle can be predicted in advance according to the first environmental granularity and the first environmental humidity within the preset time period, and the opening of the first switch group can be changed in time, thereby reducing the risk of internal environmental contamination of the electronic control due to untimely adjustment of the first switch group and improving the quality of the internal environment of the electronic control.

[0099] Reference Figure 1 and Figure 7 In one embodiment, there are multiple types of the first environmental parameters, and controlling the first switch group to adjust the air volume of the first air inlet according to the first environmental parameter at the first air inlet further includes:

[0100] S231, comparing the plurality of first environmental parameters with their respective corresponding first reference values ​​to obtain a first comparison result;

[0101] S232: When the first comparison result is that at least one of the first environmental parameters is greater than its corresponding first reference value, control the first switch group to close the first air inlet and the first air outlet.

[0102] In this embodiment, the first environmental parameter is used to reflect the air condition at the first air inlet, including water vapor, dust, etc., and multiple first environmental parameters are set to consider the actual working impact of air cooling on the internal environment of the electronic control from different dimensions.

[0103] The first comparison result includes the results of comparing a plurality of first environmental parameters, so as to close the first switch group in time when any first environmental parameter exceeds its corresponding first reference value.

[0104] The first reference value may include a first reference granularity, a first reference humidity, a first reference voltage, etc. according to the corresponding first environmental parameter, and is set by R&D personnel according to the actual tolerance critical value of the equipment.

[0105] Specifically, the first environmental parameter may include a first environmental granularity, a first environmental humidity, a first voltage, etc., and the first voltage is the voltage of components of the control board; the control board also includes a comparison module for comparing the first environmental parameter with a first reference value, including a second comparator, a third comparator, and a fourth comparator.

[0106] Uref2 is the first reference threshold, that is, the voltage threshold at which components do not need to be set at a reduced rating. Urs2 is the first voltage. F2 is the output of the second comparator. If Urs2>Uref2, F2 is a high level H, otherwise it is a low level L.

[0107] Kp is the first environment granularity, Kpref is the first reference granularity, F3 is the output of the third comparator, if Kp>Kpref, F3 is a low level L, otherwise it is a high level H.

[0108] Kw is the first ambient humidity, Kwref is the first reference humidity, F4 is the output of the fourth comparator, and if Kw>Kwref, F3 is a low level L, otherwise it is a high level H.

[0109]

[0110] Table 1 AND gate circuit truth table

[0111] Combination Fig.11 As can be seen from Table 1, when the control board receives the AND gate circuit output signal A1 as a low level L, it shuts down, thereby reducing the risk of internal environmental pollution of the electronic control due to untimely opening adjustment.

[0112] Reference Fig.10 In one embodiment, the second housing further includes a second air inlet and a second air outlet, the electric control box further includes a second switch group, and the method further includes:

[0113] S300: Control the second switch group to open or close the second air inlet and the second air outlet according to a second environmental parameter at the second air inlet.

[0114] In this embodiment, the second environmental parameter is used to reflect the air condition at the second air inlet, including water vapor, dust, etc., so that when the concentration of water vapor, dust, etc. outside is low, the second shell is ventilated, and part of the wind received by the first air inlet is heat exchanged with the second shell through the first air duct, and part is directly cooled to the internal control panel through the second air inlet. When the concentration of water vapor, dust, etc. outside is high, the second air inlet and the second air outlet are completely closed by the second switch group, so that the second shell becomes a waterproof and dustproof sealed shell, and heat exchange and cooling are only performed through the first air duct.

[0115] In one embodiment, controlling the second switch group to open or close the second air inlet and the second air outlet according to the second environmental parameter at the second air inlet includes:

[0116] S310: When the second environmental parameter is not greater than a preset second reference value, adjust the second target angle of the second switch group to a preset maximum angle, so that the second switch group cuts off the first air duct when the maximum angle is reached.

[0117] In this embodiment, the second reference value is set according to the second environmental parameter, which may specifically include a second reference particle size, a second reference humidity, etc., wherein the second reference value is set according to the critical value of the corresponding parameter that the electronic control can tolerate. The maximum angle is the opening required for the second switch group to cut off the first air duct, which is set according to actual needs.

[0118] The second switch group can be Fig.15 The curve shown in the figure adjusts the opening, or even completely cuts off the first air duct, so that the wind entering the first air inlet passes through the second air inlet to directly cool the control board, thereby maximizing the heat dissipation of the control board.

[0119] The present invention further proposes a swimming pool machine, which includes a control panel and the above-mentioned electric control box, wherein the control panel is arranged in the second shell of the electric control box; the specific structure of the swimming pool machine refers to the above-mentioned embodiment.
