Description

Technical Field

[0001] This utility model relates to the field of air conditioning auxiliary device technology, specifically an air conditioning temperature and humidity sensing device. Background Technology

[0002] A temperature and humidity sensor is an electronic device or apparatus that can simultaneously detect temperature and humidity parameters in the environment in real time and convert these physical quantities into electrical signals (such as voltage, current, or digital signals) that can be recognized by instruments. It is the "sensing core" of various temperature and humidity monitoring and control systems and is widely used in indoor environments with air conditioning.

[0003] The air outlet blows out treated cold air (for example, the outlet temperature may be as low as 16°C when cooling, which is far lower than the actual indoor temperature). If the air conditioner's temperature and humidity sensor is located here, it will mistakenly judge that "the indoor temperature has been reached" and shut down prematurely, resulting in the actual room temperature not reaching the standard. If it is located near doors, windows, or exterior walls: windows are easily affected by the outdoor environment (such as the temperature rising near windows when the sun shines directly on them in summer), and exterior walls may cause local temperature abnormalities due to the conduction of high outdoor temperatures. The sensor will mistakenly take the "local extreme temperature" as the overall indoor temperature. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides an air conditioning temperature and humidity sensing device, which solves the problems mentioned in the background section.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: an air conditioning temperature and humidity sensing device, comprising a sealed housing and a cavity formed inside the sealed housing. A temperature and humidity sensing module is fixedly installed on the inner wall of the cavity. The sealed housing also has an opening, a rotating port, and a first interface that are sequentially connected from top to bottom. The first interface is connected to the cavity. The outlet end of the first interface is located close to the temperature and humidity sensing module. A rotatable roller is rotatably arranged inside the rotating port. A guide port is formed on the rotating roller. The sealed housing also has a second interface. The outlet end of the second interface is located away from the temperature and humidity sensing module. The guide port is intermittently connected to the first interface and the second interface.

[0008] Preferably, a rotating shaft is coaxially fixedly connected to the end of the rotating roller, a damping bearing is embedded inside the sealed housing, the rotating shaft is inserted into the inner ring of the damping bearing, and a knob is fixedly connected to the end of the rotating shaft away from the rotating roller.

[0009] Preferably, the inner wall of the opening is fixedly connected with a plurality of linearly equidistant partitions, and there is a gap between two adjacent partitions to form a channel.

[0010] Preferably, a cover plate is detachably installed on the back of the sealed housing, and the cover plate is used to seal the cavity.

[0011] Preferably, the back of the cover plate is provided with a positioning structure for connection with the wall.

[0012] (III) Beneficial Effects

[0013] This utility model provides an air conditioner temperature and humidity sensing device, which has the following beneficial effects:

[0014] In this invention, two interfaces are provided, with different path distances and different spacing between them and the temperature and humidity sensing module. When the sensing device is placed near the air conditioner outlet, interface two is used, with its outlet end further away from the temperature and humidity sensing module. This allows air that has undergone a long path buffer to enter the cavity, ensuring that the sensor contacts the "average temperature and humidity after local mixing," rather than the extreme values ​​at the outlet. When the sensing device is placed near a window, interface one is used. The close-spacing design allows the sensor to directly contact the circulating air, avoiding "detection lag" caused by excessively long paths and ensuring more timely air conditioning adjustments. This device can meet flexible installation requirements, maximizing detection reliability in different installation locations, and ensuring that temperature and humidity data truly guide the precise operation of the air conditioner.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Please see Figures 3 to 6 This utility model provides a technical solution: an air conditioning temperature and humidity sensing device, including a sealed housing 1 and a cavity 101 opened inside the sealed housing 1. A temperature and humidity sensing module 4 is fixedly installed on the inner wall of the cavity 101. The sealed housing 1 also has an opening 102, a rotating port 103, and a first interface 104 arranged sequentially from top to bottom. The first interface 104 is connected to the cavity 101. The outlet end of the first interface 104 is located close to the temperature and humidity sensing module 4. A rotatable roller 2 is rotatably arranged inside the rotating port 103. A guide port 201 is opened on the roller 2. The sealed housing 1 also has a second interface 105. The outlet end of the second interface 105 is located away from the temperature and humidity sensing module 4. The second interface 105 can be designed as L-shaped or U-shaped. The guide port 201 is intermittently connected to the first interface 104 and the second interface 105.

[0025] The device is equipped with two interfaces, 104 and 105, with different path distances and different spacings between them and the temperature and humidity sensing module 4. The guide port 201 can be intermittently connected to either interface 104 or interface 105 by rotating the roller 2. When the sensing device is placed near the air conditioner outlet, interface 105 is used, with its outlet end further away from the temperature and humidity sensing module 4. This allows air that has undergone a long path buffer to enter the cavity 101, ensuring that the temperature and humidity sensing module 4 is exposed to the "locally mixed average temperature and humidity," rather than the extreme values ​​at the outlet. When the sensing device is placed near a window, interface 104 is used. The close-range design allows the temperature and humidity sensing module 4 to directly contact the circulating air, avoiding "detection lag" caused by excessively long paths and ensuring more timely air conditioning adjustments. This device allows for flexible installation, maximizing detection reliability in different installation locations, and ensuring that temperature and humidity data truly guide the precise operation of the air conditioner.

[0026] The core logic of the temperature and humidity sensor for detecting temperature is as follows: the "temperature and humidity sensing module 4" captures the changes in physical properties (such as resistance, voltage, electromotive force, etc.) caused by changes in ambient temperature and humidity, and then converts these changes in physical quantities into calculable electrical signals, ultimately deducing the actual temperature value and displaying it on the display screen on the front side of the sealed housing 1. This is the existing detection process, so it will not be described in detail.

[0027] Reference Figure 6 and Figure 7 The end of the roller 2 is coaxially fixedly connected to the shaft 6. The sealed housing 1 is equipped with a damping bearing 8. The shaft 6 is inserted into the inner ring of the damping bearing 8. The end of the shaft 6 away from the roller 2 is fixedly connected to a knob 7.

[0028] By rotating the knob 7, the rotating shaft 6 and the rotating roller 2 are driven to rotate, so that the guide port 201 is connected with the first interface 104 or the second interface 105. When the manual rotation is removed, the damping bearing 8 can ensure that the rotating shaft 6 is in the current position and will not rotate unexpectedly, and the guide port 201 is stably connected with the first interface 104 or the second interface 105.

[0029] The core function of the damping bearing 8 is to provide a stable positioning effect for the rotating shaft 6 through "damping friction", ensuring that the rotating roller 2 can maintain the current angle stably after rotating to the target position (such as docking with interface 104 or interface 2 105), avoiding "accidental rotation" caused by slight external vibration, airflow impact or accidental contact, thereby ensuring the reliability of airflow channel switching.

[0030] Reference Figures 1 to 3 as well as Figure 6 The inner wall of the opening 102 is fixedly connected with multiple linearly equidistant partitions 3, and there is a gap between two adjacent partitions 3 to form a channel.

[0031] Air containing moisture in the indoor environment enters the channel 201 through the channel, and then enters the interface 104 or interface 205 through the channel 201, and finally enters the cavity 101. The temperature and humidity sensing module 4 detects the humidity and temperature.

[0032] The temperature and humidity sensing module 4 includes the following components:

[0033] Temperature sensing unit: Common principles include the "thermometer effect" (such as NTC thermistors, whose resistance decreases as temperature increases), which can achieve temperature detection in the range of -40℃ to 125℃ or even wider.

[0034] Humidity sensing units: The mainstream type is "capacitive humidity sensing element" (such as a polymer film, whose dielectric constant changes after absorbing moisture, which is converted into a change in capacitance value), and some are "resistive humidity sensing element" (whose resistance value changes after absorbing moisture).

[0035] Reference Figure 2 and Figure 3 A cover plate 5 is detachably installed on the back of the sealed housing 1, and the cover plate 5 is used to seal the cavity 101.

[0036] Cavity 101 is the core installation area of ​​temperature and humidity sensing module 4. Its sealing is directly related to the detection accuracy. Cover plate 5, through its tight fit with the sealing housing 1 (in conjunction with silicone sealing ring), can prevent external dust from directly entering cavity 101.

[0037] Reference Figure 2 The back of cover plate 5 has a positioning structure for connecting to the wall, such as ordinary 3M double-sided tape, which can be directly pasted after cleaning the wall; or you can choose a load-bearing traceless hook, paste it on the wall, and then hang this sensor on the hook (the back of cover plate 5 must have a hanging hole).

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
