During the use of the air conditioner, moisture in the air is removed, so that the ambient humidity is continuously reduced, and if the air humidity is too low, the user experience is reduced, and even various respiratory diseases can be caused. Therefore, in the prior art, a humidity sensor is usually arranged on the air inlet side of the evaporator to detect the ambient humidity, and the detected humidity is sent to an electric control box of the air conditioner, so that the real-time ambient humidity is displayed on a display panel. However, the humidity sensor is usually arranged too close to the evaporator and is easily affected by auxiliary heat, so that the detection result is inaccurate; meanwhile, the humidity sensor usually cannot be in sufficient contact with the entering ambient wind, which affects the detection accuracy. The utility model discloses a sensor mounting structure optimizes humidity transducer's mounted position, does not receive the auxiliary heating when making it can the direct contact indoor ambient air and influences to accurate measurement indoor environment humidity.
Referring to fig. 1 to 4, a sensor mounting structure includes a mounting groove 20 provided on a rear surrounding case 2, an air inlet 21 provided on the mounting groove 20, and a humidity sensor 3 adapted to be mounted in the mounting groove 20 and to detect humidity of air flowing in from the air inlet 21. Through setting up humidity transducer in the mounting groove of enclosing the shell after, can reduce the evaporimeter and assist the influence of heat to humidity transducer detection precision for ambient air can freely get into the mounting groove, guarantees that humidity transducer and air fully contact, thereby can realize accurately measuring the indoor ambient humidity that the air conditioner located, sets up the inlet port on the mounting groove simultaneously.
In order to further reduce the influence of the additional heat of the evaporator on the humidity sensor and simultaneously improve the installation stability of the humidity sensor. The sensor mounting structure further comprises a mounting frame 10 arranged on the air supply volute 1, the humidity sensor 3 is fixed on the mounting frame 10, and the mounting frame 10 is suitable for being embedded in the mounting groove (20).
Specifically, as shown in fig. 2 and fig. 15, the shape and structure of the mounting bracket 10 are matched with the shape and structure of the humidity sensor 3, when the air conditioner is completely assembled, the humidity sensor 3 is fixed between the air supply volute 1 and the rear enclosure casing 2 through the mounting bracket 10, and because the air inlet 21 is arranged on the mounting groove 20 of the rear enclosure casing 2, the air inlet 21 penetrates through the bottom of the mounting groove 20, the position of the air inlet 21 corresponds to the position of the mounting bracket 10, that is, the indoor air entering from the air inlet 21 can directly flow to the humidity sensor 3.
Thus, the humidity sensor 3 is arranged on the air supply volute 1, so that the humidity sensor 3 and the evaporator 4 keep a certain distance, and when the air conditioner works, the humidity sensor 3 can measure the ambient humidity of the air conditioner under the condition that the air conditioner is not influenced by auxiliary heat of the evaporator 4, and the phenomenon of air temperature rise caused by being too close to the evaporator 4 is avoided, so that the detection precision of the humidity sensor 3 is influenced; meanwhile, through the air inlet 21, indoor environment air can freely enter the mounting groove 20, and the humidity sensor 3 is guaranteed to be fully contacted with the air, so that the indoor environment humidity where the air conditioner is located can be accurately measured, the measurement accuracy of the humidity sensor 3 is improved, the working reliability of the air conditioner is improved, and the technical effect of the user experience degree is increased.
Referring to fig. 5-7, the upper portion of the rear enclosure 2 is provided with an air inlet grille 22, and the air inlet grille 22 is communicated with an air inlet channel of the air supply volute 1. Since the mounting bracket 10 is disposed on the duct top cover 18 of the blower volute 1, the mounting groove 20 is correspondingly disposed at the upper edge of the air inlet grille 22. The mounting frame 10 is arranged at the air inlet of the adjacent rear enclosing shell 2, and the air quantity at the air inlet is large, so that the contact quantity of the humidity sensor 3 and the air can be improved, and the accuracy of the detection data of the humidity sensor 3 is improved.
Referring to fig. 8-9, the mounting groove 20 has a groove bottom plate 201 and a peripheral sidewall surrounding the periphery of the groove bottom plate 201, and the air inlet holes 21 are opened on the groove bottom plate 201. The slot bottom plate 201 is located on the frame of the air-intake grille 22, that is, the mounting slot 20 is a groove-shaped structure formed by the frame of the air-intake grille 22 protruding in the rear direction. Thus, when the air conditioner works, indoor environment air enters the air channel after heat exchange is carried out on the indoor environment air from the air inlet grille 22 through the evaporator 4, and flows out of the air outlet under the action of the fan, and meanwhile, the indoor environment air flows to the humidity sensor 3 through the air inlet 21; at this time, the humidity sensor 3 is not affected by the auxiliary heat due to being far away from the evaporator 4, and can be in full contact with the indoor ambient wind at the same time, thereby ensuring the detection accuracy.
The air inlet holes 21 are arranged on the groove bottom plate 201, so that the humidity of air is sensed by the humidity sensor 3 arranged on the air supply volute 1 at the first time after the air conditioner sucks indoor air, the air measured by the humidity sensor 3 is prevented from being interfered by other structures, the temperature measurement accuracy of the humidity sensor 3 is improved, and the product reliability is improved.
It can be understood that the air inlet 21 disposed on the mounting groove 20 is used for air circulation, and if the area of the air inlet 21 is too small, it cannot be ensured that the ambient air is sufficiently contacted with the humidity sensor 3; if the area of the air inlet hole 21 is too large, foreign materials are easily introduced, so that the humidity sensor 3 is contaminated or damaged. Through the utility model discloses the people tests in a large number, when the area scope of inlet port 21 was between 9mm ~ 25mm, inlet port 21 had good ventilation effect, can prevent again that people's hand or debris from touchhing humidity transducer 3, and the installation that reaches national electronic component simultaneously is not by the power consumption safety standard of people's contact, improves the security performance.
The air inlet holes 21 can be round, rectangular or square, and of course, can also be in any other shape as long as the air permeability effect is not affected when the installation setting condition is satisfied. In the present invention, the air inlet 21 is preferably square, and the side length of the square air inlet 21 is 3 mm-5 mm.
Further, for the volume of the air that the increase flowed into in the mounting groove 20, the quantity of inlet port 21 can be a plurality of, and a plurality of air vents are equipped with the multirow on the groove bottom plate 201 of mounting groove 20 from top to bottom, and every row of air vent interval is provided with a plurality ofly the utility model discloses in, the air vent is provided with 4 rows, every row 3. Of course, the air inlet holes 21 can be in other numbers and arrangement modes, and can be arranged according to actual requirements. Through the air circulation volume that improves in getting into the sensor mounting structure, and then improve the contact volume of humidity transducer 3 and air for the humidity data that humidity transducer 3 surveyed are more accurate.
For better cooperation with the mounting frame 10, as shown in fig. 7-9, the mounting groove 20 is further provided with a third rib 202 and a fourth rib 203, the third rib 202 is located at the upper side wall of the groove bottom plate 201, and the fourth rib 203 is located at the lower side wall of the groove bottom plate 201, that is, the third rib 202, the fourth rib 203 and the groove bottom plate 201 generally form a U-shaped groove structure. Referring to fig. 2, in the assembled state of the rear enclosure 2, the humidity sensor 3 and the air supply volute 1, the mounting frame 10 is embedded in the U-shaped groove structure, the third rib 202 is located above the humidity sensor 3 and shields the humidity sensor 3, so that the humidity sensor 3 is located in an independent space, and the humidity sensor 3 is prevented from being extruded by other components and damaged.
Referring to fig. 1, the air conditioner includes a housing, an air supply volute 1, an evaporator 4 and a humidity sensor 3, the housing is disposed at the outermost layer of the air conditioner and used for protecting the internal structure of the air conditioner, the housing includes a base 7, a front enclosure 5, a rear enclosure 2, side plates and a top cover 6, the front enclosure 5 and the rear enclosure 2 are disposed opposite to each other and respectively connected to the base 7, and the rear enclosure 2 is provided with an air inlet; the evaporator 4 and the air supply volute 1 are arranged in the shell to execute heat exchange work of the air conditioner, and the evaporator 4 is arranged on one side, close to the rear enclosure shell 2, of the air supply volute 1. The air supply volute 1 comprises an air inlet channel and an air channel top cover 18 positioned above the air inlet channel, and the evaporator 4 is arranged at the inlet of the air inlet channel and positioned below the air channel top cover 18. The protruding setting of mounting bracket 10 is close to 2 one ends of back enclosing shell at air supply spiral case 1, that is to say that mounting bracket 10 sets firmly the one end that is close to back enclosing shell 2 at wind channel top cap 18, and under air conditioner overall installation completion state, humidity transducer 3 fixes on mounting bracket 10 to be located in the middle of back enclosing shell 2 and the wind channel top cap 18, also be that evaporimeter 4 is located humidity transducer 3's front side below, and humidity transducer 3 passes through the electric wire and is connected with automatically controlled box (not shown in the figure).
Referring to fig. 11-13, the mounting bracket 10 includes a wall plate 11 and a mounting portion 12 disposed on the wall plate 11, wherein the mounting portion 12 is adapted to limit the sensing end 31 of the humidity sensor 3 in cooperation with the wall plate 11.
Referring to fig. 10 and 15, since the humidity sensor 3 has a T-shaped structure formed by the detecting end 31 and the connecting end 32, the width of the detecting end 31 is greater than the width of the connecting end 32, and the length of the connecting end 32 is much greater than the length of the detecting end 31. The detection terminal 31 includes a PCB and a connection board, where a section of the detection terminal having a larger width (e.g., a length in an up-down direction in fig. 15) is the PCB, and a section having a smaller width (e.g., a length in an up-down direction in fig. 15) is the connection board. The PCB is used for sensing and detecting air humidity, and the connecting plate is used for connecting the PCB with a connecting wire end; and the wiring end comprises a wiring board for leading out the circuit of the PCB, so that the key component of the humidity sensor 3 is a detection end. Therefore, by providing the mounting portion 12, the detection end 31 of the humidity sensor 3 can be fixed in a targeted manner, the protection of the detection end 31 is improved, and the damage of the microelectronic component due to instable mounting is avoided.
In addition, as shown in fig. 11-13, the mounting bracket 10 further includes a wire routing portion 13 disposed on the wall plate 11, and the wire routing portion 13 is engaged with the wall plate 11 for supporting a wire routing end 32 of the humidity sensor 3. Through setting up routing portion 13, can improve humidity sensor 3's line end 32's installation stability to make humidity sensor 3's installation more firm, guarantee like this that humidity sensor 3 can wholly steadily fix on mounting bracket 10, can not appear because of humidity sensor 3's special-shaped structure rocking, the unstable condition such as removal.
As shown in fig. 16, in the present invention, the mounting portion 12 and the routing portion 13 are in a step structure. This step structure and humidity transducer 3 detection end 31 and the step structure phase-match that the link 32 formed, the difference in height between installation position 12 and the portion of walking 13 also equals with the difference in height between the PCB board in the detection end 31 and the line end 32 for humidity transducer 3's installation is more stable.
It will be appreciated that the mounting bracket 10 is protrudingly provided at a side end of the duct top cover 18 close to the rear enclosure 2, and the wall plate 11 of the mounting bracket 10 is coplanar with an end surface of the duct top cover 18 close to an end of the rear enclosure 2.
As shown in fig. 12 to 15, the mounting position 12 includes a first supporting plate 121 and a first rib 122, both ends of the first supporting plate 121 in the width direction (i.e., in the front-back direction in fig. 12) are respectively connected to the wall plate 11 and the first rib 122, and the wall plate 11 and the first rib 122 are disposed opposite to each other. That is, a first position-limiting structure can be formed between the wall plate 11, the first supporting plate 121 and the first rib 122, and the first position-limiting structure can be used for placing the detecting end 31 of the humidity sensor 3.
Specifically, the first supporting plate 121 is perpendicular to the wall plate 11, the first rib 122 is parallel to the wall plate 11, and the detecting end 31 of the humidity sensor 3 is clamped in the first limiting structure. Because first backup pad 121 plays supporting role to humidity transducer 3, first flange 122 plays limiting displacement to humidity transducer 3, and the length (for example in the left and right directions length in fig. 12) of first backup pad 121 is greater than the length of first flange 122, and first flange 122 only need can play limiting displacement to humidity transducer 3 can.
As shown in fig. 2, 12, and 14-15, since the detecting end 31 of the humidity sensor 3 has a larger surface area and a smaller contact surface area with the first supporting plate 121, in order to improve the installation stability, the supporting rib 15 is further disposed at the periphery of the first supporting plate 121, and the supporting rib 15, the first supporting plate 121, and the wall plate 11 form a box-shaped structure. The PCB board of the detection end 31 can be accommodated in the box structure, and is supported by the first support plate 121; the connection plate of the detection end 31 presses on the support rib 15, and the support function is provided by the support rib 15. In this way, the structure of the mounting bracket 10 is further optimized, so that the shape matching degree of the mounting bracket 10 and the humidity sensor 3 is improved, and the mounting stability of the humidity sensor 3 is improved.
Since the thickness (e.g., the distance in the front-back direction in fig. 12) of the connecting plate of the detecting end 31 is greater than the thickness of the PCB, in order to prevent the connecting plate from being pressed by the back surrounding shell 2 during the installation process, the thickness (e.g., the distance in the front-back direction in fig. 12) of the first rib 122 is greater than the thickness of the supporting rib 15, that is, the farthest distance between the side of the first rib 122 away from the wall plate 11 and the wall plate 11 is not less than the farthest distance between the side of the detecting end 31 away from the wall plate 11 and the wall plate 11.
Referring to fig. 2 and 4, when the rear surrounding casing 2 and the air supply volute 1 are assembled, the mounting bracket 10 is embedded in the mounting groove 20, the humidity sensor 3 is opposite to the groove bottom plate 201 of the mounting groove 20, and the first rib 122 is clamped between the humidity sensor 3 and the groove bottom plate 201. Although the position of the air inlet 21 on the tank bottom plate 201 corresponds to the position of the humidity sensor 3, the air inlet area of the air inlet 21 is smaller than the area of the detection end 31 of the humidity sensor 3 for safety and protection reasons; in order to make the detection end 31 sufficiently contact with the indoor air, a certain space needs to be left between the tank bottom plate 201 and the humidity sensor 3 for air circulation. Therefore, when the farthest distance between the side of the first rib 122 away from the wall plate 11 and the wall plate 11 is greater than the farthest distance between the side of the detection end 31 away from the wall plate 11 and the wall plate 11, the detection accuracy can be prevented from being reduced due to the fact that the humidity sensor 3 is too close to the groove bottom plate 201 of the mounting groove 20, and the occurrence of safety accidents due to the fact that the mounting groove 20 is electrically polarized can also be reduced.
Referring to fig. 2 and 12, in order to make the sensor mounting structure meet the safety standards and prevent the humidity sensor 3 from being tightly attached to the wall plate 11 of the mounting frame 10, the wall plate 11 of the mounting frame 10 is further provided with a rib 14, and the rib 14 is located between the humidity sensor 3 and the wall plate 11 in the assembled state of the rear surrounding shell 2, the humidity sensor 3 and the air supply volute 1.
Specifically, the rib 14 is disposed on one side of the wall plate 11 close to the first support plate 121, and the rib 14 extends downward along the wall plate 11 to the first support plate 121, and may also be regarded as the rib 14 located at the connection position of the first support plate 121 and the wall plate 11; the detecting end 31 of the humidity sensor 3 is caught between the rib 14 and the first rib 122. Through setting up like this, can guarantee to be the interval setting between humidity transducer 3 and the wallboard 11, and the interval scope between humidity transducer 3 and the 11 faces of wallboard is 4mm ~ 7 mm. If the distance is less than 5mm, the safety standard can not be reached; if the distance is larger than 7mm, the optimization of the internal structure of the air conditioner is not facilitated, and the installation stability of the humidity sensor 3 is reduced.
It can be understood that the material of the convex rib 14 can be elastic material, so that the convex rib 14 has a certain deformation space, under the action of elastic deformation, the convex rib 14 can clamp the humidity sensor 3 more tightly to improve the assembly stability, and meanwhile, the elastic material can also avoid scratching the humidity sensor 3.
The end of the rib 14 can be a rounded structure, so that the humidity sensor 3 can be conveniently guided during installation, and the humidity sensor 3 can be further prevented from being scratched. In addition, the ribs 14 can also enhance the connection strength between the first support plate 121 and the wall plate 11, thereby improving the overall installation strength of the installation frame 10.
The number of the ribs 14 may be plural, and the plurality of ribs 14 are arranged at intervals, so as to further enhance the installation stability of the humidity sensor 3.
As shown in fig. 12-13, the routing portion 13 includes a second supporting plate 131 and a second blocking edge 132, two ends of the second supporting plate 131 in the width direction (i.e. the front-back direction in fig. 12) are respectively connected to the wall plate 11 and the second blocking edge 132, and the wall plate 11 and the second blocking edge 132 are disposed opposite to each other. That is, the wall plate 11, the second supporting plate 131 and the second flange 132 cooperate to form a second limiting structure, which can be used for placing the connecting wire end 32 of the humidity sensor 3. By thinning the structure of the mounting bracket 10 in this way, the shape matching degree of the mounting bracket 10 and the humidity sensor 3 is further improved, so that the mounting stability of the humidity sensor 3 can be increased.
The wiring part 13 further comprises a stopper 133 arranged on the wall plate 11, the stopper 133 is parallel to the second support plate 131, and in the assembled state of the humidity sensor 3 and the mounting bracket 10, the stopper 133 is located above the humidity sensor 3 to protect the wiring end 32 of the humidity sensor 3 and prevent other components in the air conditioner from extruding the humidity sensor 3.
Corresponding to the mounting position 12, as shown in fig. 12, the left and right ends of the third baffle are respectively provided with support ribs 15, and the connecting line end 32 is pressed on the support ribs 15.
It can be understood that, mounting bracket 10 and air supply spiral case 1, mounting groove 20 and back enclose shell 2 and all can adopt the integral type structure, with mounting bracket 10 and air supply spiral case 1, mounting groove 20 and back enclose shell 2 through integral type shaping design, mounting bracket 10 and air supply spiral case 1 can be removed from, mounting groove 20 and back enclose the connection structure between shell 2, the manufacturing cost of product has been reduced by a wide margin when saving assembling process, and there is not the connection section in integral type shaping structure, make mounting bracket 10 and air supply spiral case 1, mounting groove 20 and back enclose the junction of shell 2 and can bear bigger moment, avoid the erection joint to appear damaging in the work, play and simplify the product assembling process, reduce product manufacturing cost, prolong product life, promote the technical effect of product job stabilization nature and reliability.
