[0002] As people's living standards continue to improve, their demands for quality of life also increase. Elevators are an indispensable product in people's daily travel. However, elevator cars are enclosed and small activity spaces, so the air environment is naturally relatively poor. Therefore, elevator air conditioning has emerged as an air conditioning device that is suitable for changing the air environment of elevator cars.

[0003] Condensation frequently occurs during air conditioning cooling operation. Effectively solving the condensation problem in elevator air conditioning systems has always been one of the technical challenges in air conditioning product development. Generally, it requires detecting environmental parameters such as indoor temperature and humidity to determine if the air conditioner has reached the conditions for condensation, thereby adjusting the compressor frequency and indoor fan speed to prevent condensation. However, temperature sensors are inconvenient to install inside elevator cars, causing inconvenience during maintenance. Summary of the Invention

Detailed Implementation

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0051] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0052] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0053] Example 1

[0054] Reference Figures 1-6 This is the first embodiment of the present invention, which provides an intelligent dew point controlled elevator air conditioner. Because indoor ambient temperature detection instruments are easily damaged or inaccurate in reality, requiring regular maintenance, the present invention designs a device that allows for quick plugging and unplugging, thus improving work efficiency. It also solves the technical problem of inconvenient installation inside the elevator car, eliminating the need to pre-drill holes and reducing manufacturing difficulty.

[0055] Specifically, it includes an air conditioner 100, which has an air outlet 102 and a return air outlet 103 connected to the elevator car via pipes; the return air outlet 103 is provided with a return air cover 104 at the connection end between the pipe and the elevator car, and the air outlet 102 is provided with an air outlet cover 107 at the connection end between the pipe and the elevator car.

[0056] The indoor temperature detection unit 105 is plugged into the return air cover 104;

[0057] Temperature and humidity detectors are respectively installed at both ends of the air outlet shroud 107 to obtain the supply air temperature and supply air humidity corresponding to the air conditioning unit; based on the supply air temperature and supply air humidity, the dew point temperature corresponding to the supply airflow of the air conditioning unit is determined.

[0058] The first temperature difference between the indoor ambient temperature and the set temperature obtained by the indoor temperature detection unit 105 and the second temperature difference between the dew point temperature and the indoor ambient temperature are determined. The compressor frequency and indoor fan speed are adjusted according to the first temperature difference to change the surface temperature of the heat exchange tube, so that the second temperature difference is kept within the set range to achieve no condensation.

[0059] Preferably, since installing temperature or humidity detectors inside the elevator car requires pre-drilling and wiring, installation is inconvenient. The temperature and humidity detectors in this invention can also be connected to the exhaust hood 107 using the same connection method as the first temperature detector 105 and the return air hood 104. Their structures can be completely identical, with the temperature and humidity detectors respectively connected to both ends of the exhaust hood 107.

[0060] Preferably, compared to the prior art, because the second detector and humidity detector are located on the air outlet hood 107 in this invention, the dew point temperature is obtained at the temperature of the air outlet, since condensation generally starts from the air outlet. The indoor temperature detection unit 105 is located at the return air vent to detect the indoor temperature. Therefore, the indoor temperature detected by the first temperature detection unit 105 is very accurate. Thus, the set indoor temperature range must be higher than the dew point temperature. This allows for adjustment of the compressor frequency and the indoor fan speed to achieve condensation-free operation.

[0061] Ideally, the indoor temperature can also be determined by averaging the data measured by the first temperature detector and the data measured by the second temperature detector.

[0062] Preferably, the indoor fan speed and compressor frequency are adjusted by PID control, which is a standard technology and will not be elaborated further.

[0063] Furthermore, the air conditioner 100 has mounting grooves around its bottom, and a fastener 101 is installed in the mounting grooves;

[0064] The fastener 101 has an U-shaped structure and is fixedly connected to the mounting slot of the air conditioner 101;

[0065] The mounting assembly 200 includes two sets of mounting brackets fixedly connected to the fastener 101, with a predetermined distance between the two sets of mounting brackets.

[0066] It should be noted that setting a mounting groove at the bottom of the air conditioner ensures that the air conditioner will not be inconvenient to transport due to the protruding mounting device at the bottom.

[0067] Preferably, the elevator car will have a pre-reserved installation area for the return air hood 104 and a return air inlet. The return air hood 104 and the return air hood 107 are inserted into the installation area.

[0068] Furthermore, the mounting component 200 is fixedly installed on the crossbeam at the top of the elevator car, and cooperates with the fixing component 101 to fix the air conditioner 100.

[0069] The mounting bracket includes a fixing plate 201 disposed on both sides of the crossbeam, a screw 202 passing through the fixing plate 201 and the fixing member 101, and fasteners 203 disposed at both ends of the screw 202; the fixing plate 201 has a plurality of adjustment holes along its length; the fixing member 101 has locking holes corresponding to the adjustment holes; a gasket 204 is disposed between the fixing plate 201 and the fixing member 101.

[0070] It should be noted that the adjustment hole can be adjusted according to the size of the air conditioner, making it suitable for different types of air conditioners.

[0071] Preferably, fastener 103 is a locking nut.

[0072] Preferably, the function of the 204 gasket is noise reduction, because the air conditioner is installed on the top of the elevator car and will generate vibration and noise when it is running. Using the 204 gasket can reduce the transmission of sound and achieve the effect of noise reduction.

[0073] Furthermore, a ventilation opening for pipe connection is provided on one side of the return air hood 104; a fixing frame 106 is provided on one side of the ventilation opening, the fixing frame 106 has a plug-in groove, the indoor temperature detection unit 105 is adapted to the plug-in groove, an opening is provided at the end of the plug-in groove away from the pipe, and an U-shaped baffle 107 is provided on one side of the opening; a support member is provided in the plug-in groove, and a release member is provided at the bottom of the support member.

[0074] It should be noted that the function of the U-shaped baffle 107 is to surround the indoor ambient temperature measuring instrument to reduce the formation of convection at the air outlet, which would cause inaccurate data. The opening end of the U-shaped baffle 107 is far away from the ventilation opening of the return air cover 104.

[0075] Preferably, the support member is used to limit the indoor environmental monitoring unit 105, while the release member is used to disassemble the indoor environmental monitoring unit 105.

[0076] Furthermore, the indoor temperature detection unit 105 includes:

[0077] Press rod 105a, one end of which is provided with an indoor temperature detector that penetrates the opening;

[0078] The first elastic element 105b is disposed on the inner side wall of the insertion groove near the through opening;

[0079] Mounting block 105c is disposed on the rod body of pressing rod 105a and is in transmission cooperation with elastic element 105b;

[0080] Locking element 105d is located at the end of the pressing rod 105a that is away from the indoor temperature detector;

[0081] The limiting member 105e is disposed between the mounting block 105c and the locking member 105d.

[0082] It should be noted that the indoor temperature detector can be installed by plugging it into the push-button 105a.

[0083] Preferably, the first elastic element is the spring at position 105b.

[0084] Preferably, the pressing rod 105a is first inserted into the opening of the fixing frame 106, so that the bottom end face of the mounting block 105c contacts the first elastic member 105b. Then, the pressing rod 105a is pressed so that the limiting member 105e abuts against the bottom of the support member in the insertion groove to fix it, thus fixing the position of the pressing rod 105a, so that the indoor temperature detector can extend from the opening to detect the temperature. When disassembly is required, the pressing rod 105a is pressed again so that the limiting member 105e contacts the release member in the insertion groove, and the locking member 105d engages with the limiting member 105e to remove the entire pressing rod 105a. The end face of the insertion groove can be covered with a cover to close it with the fixing frame 106, or it can be closed by inserting a flexible material such as cotton cloth into the insertion groove.

[0085] Furthermore, the limiting member 105e includes: two sets of fixing blocks 105e-1, symmetrically arranged along the axis of the pressing rod 105a and disposed on the outer side wall of the pressing rod 105a, the fixing blocks 105e-1 having a rotating groove; it also includes a swing block 105e-2, one end of which is rotatably connected to the inner side wall of the rotating groove; a torque spring is disposed between the swing block 105e-2 and the fixing block 105e-1; the maximum rotation angle between the swing block 105e-2 and the fixing block 105e-1 is 90 degrees.

[0086] It should be noted that the rotating groove of the fixed block 105e-1 has an opening, and the bottom of the opening has a blocking plate. Therefore, when the two sets of swing blocks 105e-2 rotate, they can only rotate up to a maximum of 90 degrees.

[0087] Furthermore, the locking member 105d includes: two sets of receiving blocks 105d-1, symmetrically arranged along the axis of the pressing rod 105a and disposed on the outer side wall of the pressing rod 105a, the receiving blocks 105d-1 having locking grooves; it also includes a locking pin 105d-2, which passes through the receiving blocks 105d-1 and is slidably connected to them; the free end of the pin 105d-2 is chamfered; it also includes a second elastic member 105d-3, disposed between the locking pin 105d-2 and the outer side wall of the receiving block 105d-2.

[0088] Furthermore, the support member includes two triangular blocks 106a disposed opposite to each other on the inner sidewall of the mounting groove. The hypotenuses of the two sets of triangular blocks 106a are disposed opposite to each other, so that the insertion space of the insertion groove gradually decreases.

[0089] Furthermore, the release element includes a wedge-shaped block 106b disposed at the bottom of the triangular block 106a, and a certain distance is preset between the wedge-shaped block and the triangular block 106a; the distance of the wedge-shaped block 106b to the indoor temperature detection unit 105 is smaller than the distance between the triangular block 106a and the indoor temperature detection unit 105.

[0090] The wedge block 106b has an oblique edge at the bottom of the triangular block 106a.

[0091] It should be noted that the second elastic element 105d-3 is a spring.

[0092] Preferably, the entire installation process is as follows: First, during the insertion of the pressing rod 105a into the through-hole, the mounting block 105c contacts the spring. At this time, the edges of the two sets of swing blocks 105e-2 contact the inclined surface of the triangular block 106a, and under the pressure given by the inclined surface, the two sets of swing blocks 105e-2 move closer to the axis of the pressing rod 105a. The pressing rod 105a is pressed further so that the two sets of swing blocks 105e-2 contact the largest edge of the triangular block 106a. Finally, the swing blocks 105e-2 pass the triangular block 106a. Under the action of the torque spring, the two sets of swing blocks 105e-2 move away from the axis of the pressing rod 105a, because the maximum rotation angle between the swing blocks 105e-2 and the fixed block 105e-1 is 90 degrees. Ultimately, the position is perpendicular to the axis of the pressing rod 105a. When the pressing rod 105e-2 is released, it moves back under the action of the first elastic element 105b. The swing block 105e-2 and the bottom of the triangular block 106a abut against the first elastic element 105b, achieving a fixing effect. It should be noted that a pressing depth indicator is set at the end of the pressing rod 105a, the end furthest from the indoor ambient temperature sensor. This allows the operator to observe the pressing depth and release the rod when both sets of swing blocks 105e-2 are horizontal, i.e., at the bottom of the triangular block 106a. Of course, the operator can also release the rod depending on the ease of pressing, because when the swing block 105e-2 is between the triangular block 106a and the wedge block 106b, there is no resistance except for the first elastic element 105b. This perfectly secures the entire pressing rod 105a. At this point, because the hypotenuses of the triangular block 106a are positioned opposite each other, it can provide support when the cotton cloth is inserted for sealing.

[0093] Preferably, the top edge of the wedge block 106b is a bevel, providing a larger space for the swing block 105e-2 to swing back and forth, achieving an effect parallel to the axis of the pressing rod 105a.

[0094] Preferably, when it is necessary to remove the pressing rod 105a, continue pressing the pressing rod 105a until the edge of the swing block 105e-2 contacts the edge of the wedge block 106b, causing the swing block 105e-2 to move closer to the axis of the pressing rod 105a until the swing block 105e-2 contacts the chamfered edge of the locking pin 105d-2 and engages in the locking groove. The locking pin 105d-2 then returns to its original position, thus limiting the movement of the swing block 105e-2. At this point, it can be easily removed from the insertion slot of the fixing frame 106, allowing for the replacement or repair of the indoor temperature measuring instrument.

[0095] Preferably, because there is a predetermined distance between the wedge block and the triangular block 106a, the swing block 105e-2 will not come into contact with and lock the locking member 105d during installation. The distance between the wedge block 106b and the indoor temperature detection unit 105 is smaller than the distance between the triangular block 106a and the indoor temperature detection unit 105. This is so that when the wedge block 106b comes into contact with the swing block 105e-2, the wedge block 106b provides a guiding force to lock the swing block 105e-2 in the locking groove of the receiving block 105d-1.

[0097] Step 1: Connect the indoor temperature detection unit to the return air hood;
