In order to simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present disclosure provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

An electronic control box assembly 100 according to an embodiment of the present invention is described below with reference to the drawings.

As shown in fig. 1 and 2, according to the electric control box assembly 100 of the embodiment of the present invention, the electric control box assembly 100 is used in an air treatment apparatus 1000. It should be noted that the air processing device 1000 may be a device such as an air purifier, and may also be a device such as an air conditioner or a bathroom heater, and is not limited herein.

Specifically, the air treatment device 1000 includes a housing 200, and the housing 200 defines therein a first heat exchange air duct 201 and a second heat exchange air duct 202 which are independent. That is, the first heat exchange air duct 201 and the second heat exchange air duct 202 can simultaneously perform heat exchange conditioning of air. In a specific example of the present invention, the first heat exchange air duct 201 has a first air inlet and a first air outlet 207, and the evaporator is disposed at a position adjacent to the first air inlet in the first heat exchange air duct 201. Therefore, outside air can enter the first heat exchange air duct 201 through the first air inlet, and air flow is cooled and adjusted through the evaporator and then is discharged through the first air outlet 207. At this time, the air temperature in the first heat exchange air duct 201 is low.

In addition, the second heat exchange air duct 202 has a second air inlet (not shown) and a second air outlet 208, and the condenser is disposed in the second heat exchange air duct 202 at a position adjacent to the second air inlet. Therefore, outside air can enter the second heat exchange air duct 202 through the second air inlet, and the air flow is discharged through the second air outlet 208 after being heated and adjusted while flowing through the condenser. At this time, the air temperature in the second heat exchange air duct 202 is higher.

In the related art, the electric control box is placed in the air conditioner, so that the installation position of the electric control box is close to the heat exchange air duct, and in the using process of the electric control box, components in the electric control box generate heat while running. When the air conditioner refrigerates, the air temperature inside the air conditioner is lower, namely the ambient temperature of the electric control box is lower, and because the temperature inside the electric control box is higher, condensation is easy to generate inside the electric control box, and the condensation easily causes failure risks such as short circuit of a circuit inside the electric control box. When air conditioning is carried out, the air temperature inside the air conditioner is higher, namely the environment temperature of the electric control box is higher, and the temperature inside the electric control box is not favorable for outward diffusion of the temperature inside the electric control box when the temperature inside the electric control box is higher, so that the heat dissipation effect is poor, and long-time high-temperature treatment is also not favorable for normal operation of internal components of the electric control box.

In addition, because automatically controlled box is placed in the inside of air conditioner for in the installation and the maintenance process of carrying out automatically controlled box, operating personnel all need dismantle the shell of air conditioner, just can carry out the installation or the maintenance work of automatically controlled box, has increased operating personnel's work load, makes the installation of automatically controlled box, maintains the degree of difficulty height.

Specifically, when first heat transfer wind channel 201 carries out the cooling regulation of air, can better separation low temperature in the first heat transfer wind channel 201 through casing 200 to the interference of automatically controlled box subassembly 100 to avoid the inside condensation that produces of automatically controlled box, and then reduce the inside inefficacy risk that causes because of the condensation of automatically controlled box subassembly 100.

In addition, when second heat transfer wind channel 202 carries out the intensification regulation of air, can better separation the high temperature in the second heat transfer wind channel 202 to the interference of automatically controlled box subassembly 100 through casing 200 for the heat that automatically controlled box subassembly 100 operation in-process produced can normally spread to the outside, thereby promotes the radiating efficiency of automatically controlled box subassembly 100, and then guarantees the operating stability of automatically controlled box subassembly 100.

On the other hand, in the maintenance process of the electronic control box assembly 100 in the later period, because the electronic control box assembly 100 is located outside the casing 200, when the electronic control box assembly 100 is installed and maintained in the later period, an operator does not need to detach the casing 200, and the installation and maintenance difficulty of the electronic control box assembly 100 is reduced.

It can be understood that the matching mode of the hook 1 and the hook hole 203 is simple, and after the hook 1 is hung in the hook hole 203, the hook hole 203 can better limit the freedom degree of movement of the hook 1. Therefore, the clamping hook 1 is limited through the clamping hole 203, so that the electronic control box assembly 100 is fixed on the shell 200, and the positioning and mounting difficulty of the electronic control box assembly 100 can be well reduced. In addition, in the process of later maintenance of the electronic control box assembly 100, the hook 1 is taken out from the clamping hole 203, so that the electronic control box assembly 100 can be detached from the outer wall of the shell 200, the detaching difficulty of the electronic control box assembly 100 is small, and the maintenance difficulty of the electronic control box assembly 100 is reduced.

In a specific embodiment, referring to fig. 3 and 5, the opening of the hook 1 faces downward, when the electronic control box assembly 100 is assembled, the hook 1 is placed in the hook hole 203, and under the action of gravity of the electronic control box assembly 100, the hook 1 has a tendency to move downward, so that the lower end of the hook hole 203 is located in the opening of the hook 1, thereby limiting the degree of freedom of movement of the electronic control box assembly 100 facing downward. Therefore, when the electronic control box assembly 100 does not receive an upward acting force, the electronic control box assembly 100 and the housing 200 maintain a clamping state. When the electronic control box assembly 100 needs to be detached, the electronic control box assembly 100 is lifted upwards, so that the hook 1 and the clamping hole 203 are separated from clamping fit, and the hook 1 is taken out of the clamping hole 203, so that the detaching difficulty is low.

Optionally, the number of the hooks 1 is multiple, the hooks 1 are spaced apart in the length direction of the electronic control box assembly 100, the number of the hook holes 203 is multiple, and the hook holes 203 are matched with the hooks 1 in a one-to-one correspondence manner. From this, behind the cooperation of the trip 1 of multiunit one-to-one and card hole 203, through a plurality of card holes 203 to a plurality of trip 1 spacing, increased the hookup location between the outer wall of automatically controlled box subassembly 100 and casing 200, do benefit to the joint strength between reinforcing automatically controlled box subassembly 100 and the casing 200.

It can be understood that the two sets of corresponding hooks 1 and the corresponding hook holes 203 are easy to align and cooperate, so that the positioning difficulty and the installation difficulty of the electronic control box assembly 100 are reduced.

It should be noted that, the plurality of hooks 1 may also be disposed along the width direction of the electronic control box assembly 100, and a plurality of hooks 1 disposed along the length direction and a plurality of hooks 1 disposed along the width direction may also be disposed at the same time, which is not limited herein.

Optionally, a support base 204 is attached to an outer wall of the housing 200, and the electronic control box assembly 100 is disposed on the support base 204. It is appreciated that the support base 204 can better support the electronic control box assembly 100, which can be beneficial to enhance the stability of the electronic control box assembly 100 after installation.

In one embodiment, as shown in fig. 4 and 7, the electrical control box assembly 100 is mounted on the front wall of the housing 200, the support base 204 is disposed on the front wall of the housing 200, the support base 204 protrudes from the front wall of the housing 200, and the support base 204 has a length greater than the electrical control box assembly 100 in the left-right direction. In addition, the card hole 203 is arranged above the support table 204, after the hook 1 is hung in the card hole 203, the back side of the electronic control box assembly 100 is abutted against the front wall of the shell 200, and the top wall of the support table 204 is abutted against the bottom side of the electronic control box assembly 100, so that the electronic control box assembly 100 can be well and upwards supported. Therefore, the electronic control box assembly 100 can be better supported through the shell 200 and the support table 204, so that the stability of the electronic control box assembly 100 after installation is ensured, and meanwhile, the influence of the gravity of the electronic control box assembly 100 on the strength of the hook 1 can be better reduced.

Further, the electronic control box assembly 100 is connected to the support base 204 by fasteners. Therefore, the relative position relation between the electric control box assembly 100 and the support table 204 can be well fixed, and the connection stability of the electric control box assembly 100 after installation is enhanced.

In one embodiment, as shown in fig. 6, the electrical control box assembly 100 has two connecting portions 25 protruding from the bottom side, and each connecting portion 25 has a first connecting hole 251. In addition, as shown in fig. 4, two second connection holes 205 are formed on the front wall of the support base 204 at intervals in the left-right direction, and after the electronic control box assembly 100 is hung on the outer wall of the housing 200 by the hook 1 and the hook hole 203, the first connection hole 251 faces the second connection hole 205, and then the connection part 25 is fixed on the support base 204 (refer to fig. 7) by passing through the first connection hole 251 and the second connection hole 205 in sequence through a fastener, that is, the lower end of the electronic control box assembly 100 is fixedly connected with the support base 204. Therefore, the situation that the electric control box assembly 100 moves upwards to cause the clamping hole 203 separated from the clamping hook 1 can be well avoided, and the connection stability of the electric control box assembly 100 after installation is enhanced.

In some embodiments of the present invention, as shown in fig. 3 and 8, the electronic control box assembly 100 includes: a box body 2, a box cover 3 and a partition plate 4. Wherein the case body 2 defines an accommodation chamber 21, and the case body 2 has an open port 22 communicating with the accommodation chamber 21. Therefore, the accommodating cavity 21 can better accommodate components such as the circuit board 5 of the electronic control box component 100, and the opening 22 reduces the installation difficulty when the components such as the circuit board 5 are placed into the accommodating cavity 21.

Further, a partition plate 4 is provided in the accommodation chamber 21, and the partition plate 4 is used to divide the accommodation chamber 21 into a first mounting chamber 211 and a second mounting chamber 212. It is understood that the first mounting cavity 211 and the second mounting cavity 212 may be used to receive modules, respectively, and the two modules may be separated by the first mounting cavity 211 and the second mounting cavity 212. For example, in an example of the present invention, the first mounting cavity 211 is used for receiving the circuit board 5, and the second mounting cavity 212 is used for receiving the connecting wire 300, specifically, the circuit board 5 is located on one side of the partition plate 4, and the connecting wire 300 is located on the other side of the partition plate 4. Therefore, the circuit board 5 and the connecting wires 300 are respectively arranged on the two sides of the partition plate 4, the possibility that an operator contacts the circuit board 5 when the connecting wires 300 are installed or butted is reduced, and the failure risk of electrostatic breakdown caused by the fact that the operator accidentally touches the circuit board 5 is avoided.

Further, as shown in fig. 2 and 3, the box cover 3 is coupled with the box body 2 to close the open opening 22. Therefore, the box cover 3 can better prevent the module arranged in the box body 2 from separating from the accommodating cavity 21, and simultaneously can better prevent dirt such as dust of the external environment and the like from entering the accommodating cavity 21 to be accumulated so as to improve the capacity of the circuit board 5 for resisting the interference of the external environment. For example, in an example of the present invention, the first mounting cavity 211 is used for receiving the circuit board 5, the second mounting cavity 212 is used for receiving the connection line 300, after the circuit board 5 and the connection line 300 are respectively installed in the first mounting cavity 211 and the second mounting cavity 212, the opening 22 is sealed and opened by the lid 3, which not only can better avoid the circuit board 5 and the connection line 300 to break away from the containing cavity 21, so as to improve the reliability of the whole structure of the electronic control box assembly 100, but also can better prevent dirt such as dust from entering the containing cavity 21 and accumulating, so as to improve the capability of the circuit board 5 for resisting the external environment interference.

In a specific example, as shown in fig. 6, a plurality of first fixing members 28 are provided in the first mounting cavity 211, the plurality of first fixing members 28 are spaced along a peripheral wall of the first mounting cavity 211, and after the circuit board 5 is placed in the first mounting cavity 211, the position of the circuit board 5 is limited by the plurality of first fixing members 28, so as to ensure that the circuit board 5 is firmly connected with the box body 2. In addition, have a plurality of second mounting 29 in the second installation cavity 212, a plurality of second mounting 29 set up along the width direction interval of box body 2, and second mounting 29 is used for centre gripping connecting wire 300, in the position of fixed connection line 300 for the holistic line of walking of connecting wire 300 is comparatively pleasing to the eye clean and tidy, does benefit to the discernment degree of difficulty when reducing connecting wire 300 later maintenance.

In some embodiments of the utility model, as shown in fig. 3, the electronic control box assembly 100 is still including installing the circuit board 5 of first installation cavity 211 and taking in the connecting wire 300 in second installation cavity 212, as shown in fig. 5, fig. 8 and fig. 16, be equipped with line hole 41 on the division board 4, be equipped with line groove 23 on the lateral wall of second installation cavity 212, be equipped with patch cord 51 on the circuit board 5, the one end and the circuit board 5 of patch cord 51 are connected, the other end of patch cord 51 passes in line hole 41 stretches into second installation cavity 212, the one end of connecting wire 300 is connected with the other end of patch cord 51, the other end of connecting wire 300 is suitable for passing line groove 23 and outwards extends. That is, the connection position of the patch cord 51 and the connection cord 300 is located in the second mounting cavity 212.

It is understood that the air treatment device 1000 generally has units such as a compressor, an evaporator, a condenser, etc. therein, and the circuit board 5 can be preferably connected to the plurality of units such as the compressor, etc. by the connection lines 300. That is, one end of the connection line 300 extending toward the outside of the second mounting cavity 212 is connected to a unit such as a compressor. Specifically, through the connection between the connection line 300 and the patch cord 51, a complete signal transmission path can be formed between the circuit board 5 and units such as a compressor, so that control signals generated on the circuit board 5 can be transmitted to a plurality of air conditioning units, and further, the control of functions such as switching and mode switching of the air treatment device 1000 is realized.

Therefore, the connecting position of the patch cord 51 and the connecting line 300 is arranged in the second mounting cavity 212, so that an operator can perform a connecting process of the patch cord 51 and the connecting line 300 in the second mounting cavity 212, and the possibility that the operator contacts the circuit board 5 when performing the connecting process of the patch cord 51 and the connecting line 300 is favorably reduced. It can be understood that the circuit board 5 usually has a plurality of tiny electronic components, and when an operator carelessly touches the circuit board 5 without eliminating static electricity, static electricity carried by the operator is transferred to the circuit board 5, which is likely to cause electrostatic breakdown of the tiny electronic components, thereby causing the circuit board 5 to fail. Therefore, by arranging the connection position of the patch cord 51 and the connection cord 300 in the second mounting cavity 212, the failure risk of electrostatic breakdown caused by the fact that an operator accidentally touches the circuit board 5 can be well avoided.

In one embodiment, as shown in fig. 4, a threading hole 206 is formed on an outer wall of the housing 200 adjacent to the electronic control box assembly 100, an end of the connecting wire 300 extending toward the outside of the second mounting cavity 212 passes through the threading hole 206 and extends toward the inside of the housing 200, and an end extending toward the inside of the housing 200 is connected to a compressor or other components inside the air treatment apparatus 1000. Therefore, the connecting difficulty of the connecting line 300 and units such as a compressor is reduced.

In some embodiments of the present invention, the opening 22 includes a first opening communicating with the first mounting cavity 211 and a second opening communicating with the second mounting cavity 212. Specifically, the circuit board 5 is placed in the first mounting cavity 211 through the first opening, and the connecting wire 300 is placed in the second mounting cavity 212 through the second opening, so that the interference risk in the mounting process of the circuit board 5 and the connecting wire 300 is reduced.

Further, as shown in fig. 2 and 3, the box cover 3 includes: a first cover 31 and a second cover 32. As shown in fig. 12 and 13, the first cover 31 is connected to the box body 2, the first cover 31 is used for sealing the first open opening, as shown in fig. 2 and 14, the second cover 32 is connected to the cover 3, and the second cover 32 is used for sealing the second open opening.
