It is also called a temperature control switch, a temperature protector, a temperature controller, or simply a thermostat. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller issues a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect. The application range of thermostats is very wide. According to different types of thermostats, they are used in many products such as home appliances, motors, refrigeration or heating.

[0003] At present, in the existing technology, the thermostat is assembled through the outer shell and the door, and the door and the outer shell are firmly fixed by screws to prevent the internal components from being damaged. This operation is convenient and fast. However, when the internal components of the outer shell need to be repaired, the screws need to be removed with the help of auxiliary tools, which is time-consuming and labor-intensive.

[0004] Therefore, it is particularly important to improve the existing thermostats used in HVAC control systems, design a new thermostat used in HVAC control systems to solve the above technical defects, and improve the practicality of the overall thermostat used in HVAC control systems.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] Example:

[0024] See also Figure 1-Figure 4 , the utility model provides a technical solution:

[0025] A thermostat for a heating, ventilation and air conditioning control system, comprising an outer frame 1, a through slot 2 is provided on the front of the outer frame 1, a box door 3 is installed inside the through slot 2, a visual glass 4 is installed inside the box door 3, a control button and a display screen are respectively provided outside the box door 3, and quick-release components 5 are symmetrically installed on the left and right sides of the control button outside the box door 3;

[0026] The quick-release assembly 5 is used for quick disassembly and installation between the outer frame 1 and the door 3 .

[0027] Among them, see Figure 2 and Figure 3In this embodiment, the quick-release assembly 5 includes a frame 501, a slide groove 502, a slider 503, and a clip 504. The frame 501 is installed inside the door 3, the slide groove 502 is symmetrically opened inside the frame 501, the slider 503 is installed inside the slide groove 502, and the clip 504 is installed inside the frame 501. The HVAC temperature is regulated by the thermostat. By pressing the control button up and down, the real-time temperature will be displayed on the display screen. When the thermostat is damaged and its internal components need to be replaced or repaired, the slider 503 is moved to make the two groups of sliders 503 approach each other. Secondly, the slider 503 is limited by the slide groove 502, so that the slider 503 moves along a straight line, so that the clip 504 shrinks into the frame 501, so that the door 3 and the through groove 2 are released, so that the door 3 can be easily disassembled and the internal components of the outer frame 1 can be better repaired.

[0028] Furthermore, please see Figure 2 and Figure 3 In this embodiment, through holes are provided at the top and the bottom of the frame 501, and the card strip 504 extends to the outside of the frame 501 through the through holes, and the card strip 504 is connected to the slider 503 in a fixed connection. Through the design of the fixed connection between the slider 503 and the card strip 504, the card strip 504 follows the movement of the slider 503, and the through holes are used to improve the smoothness of the card strip 504 when completing the extension and retraction work.

[0029] Furthermore, please see Figure 2 and Figure 3 In this embodiment, the slider 503 is designed in a triangular shape, and the end of the card strip 504 away from the frame 501 is designed in an arrow-shaped structure. A partition 505 is installed in the middle of the frame 501, and a fixing plate 506 is installed above and below the partition 505. A first spring 507 is installed between the fixing plate 506 and the partition 505. The triangular design of the slider 503 makes the slider 503 fit the finger more closely, making the sliding smoother. The telescopic function of the first spring 507 makes the first spring 507 always squeeze the card strip 504. At the same time, the arrow-shaped design of the card strip 504 makes it easier to insert the card strip 504 into the rectangular box 6.

[0030] For further information, see Figure 2 and Figure 4In this embodiment, a rectangular box 6 is symmetrically installed inside the through slot 2, a connecting slot 7 is opened inside the rectangular box 6, a slide bar 8 is symmetrically installed inside the connecting slot 7, and a second spring 9 is sleeved on the outside of the slide bar 8. When the clamping strip 504 is inserted into the rectangular box 6, it is extended to the inside of the connecting slot 7 through its vertical design, thereby squeezing the slide bar 8. The second spring 9 is again expanded and contracted to store energy, so that the slide bar 8 and the clamping strip 504 are squeezed against each other, thereby increasing the stability of the connection between the clamping strip 504 and the connecting slot 7.

[0031] For further information, see Figure 2 and Figure 4 In this embodiment, grooves 301 are provided at the top and bottom of the box door 3 at positions corresponding to the rectangular box 6. The box door 3 is connected to the through slot 2 through the grooves 301. A heat dissipation net 101 is provided on the outside of the outer frame 1. The grooves 301 are adapted to be used with the rectangular box 6, so that the box door 3 and the through slot 2 fit perfectly. The heat dissipation net 101 is used to effectively dissipate the heat inside the outer frame 1, thereby completing its internal overload, causing the temperature to rise, and extending its service life.

[0032] For further information, see Figure 1 and Figure 2 In this embodiment, a square groove 10 is provided below the visible glass 4, a moving block 11 is installed inside the square groove 10, and a scraper 12 is installed at one end of the moving block 11 away from the square groove 10. When the temperature difference between the inside of the outer frame 1 and the outside is large, fog appears inside the visible glass 4. By sliding the moving block 11, the moving block 11 moves inside the square groove 10, so that the scraper 12 scrapes the visible glass 4 to eliminate the fog.

[0033] In this embodiment, the implementation scenario is specifically as follows: the HVAC temperature is regulated by the thermostat, and the real-time temperature is displayed on the display screen by pressing the control button up and down. When the thermostat is damaged and its internal components need to be replaced or repaired, the two groups of sliders 503 are moved close to each other by toggling the sliders 503, and then the sliders 503 are limited by the slide grooves 502, so that the sliders 503 move along a straight line, so that the card strips 504 are contracted into the frame 501 and leave the rectangular box 6, so that the door 3 and the through groove 2 are released, so that the door 3 can be easily disassembled and better controlled. When the internal components of the outer frame 1 need to be repaired and installed, the telescopic function of the first spring 507 is used to make the first spring 507 always squeeze the clamping strip 504. At the same time, the arrow-shaped design of the clamping strip 504 allows the clamping strip 504 to be inserted into the interior of the rectangular box 6. Through its vertical design, it extends to the interior of the connecting groove 7, thereby squeezing the slide bar 8. The second spring 9 stores energy through telescopic movement again, so that the slide bar 8 and the clamping strip 504 are squeezed against each other, thereby increasing the stability of the connection between the clamping strip 504 and the connecting groove 7. The groove 301 is adapted for use with the rectangular box 6, so that the box door 3 and the through groove 2 fit perfectly.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
