Description

Technical Field

[0001] The utility model relates to the technical field of temperature controllers, and particularly relates to an open-type temperature controller. Background Art

[0002] According to the temperature change of the working environment, the local structure inside the temperature controller changes in form or volume, driving the heat medium to close or open, so as to keep the ambient temperature within the set temperature range. Therefore, it is widely used in air-conditioning systems. Although the induction head of the temperature controller used in the air-conditioning system is installed inside the air conditioner, it is actually in contact with the indoor air to ensure the accuracy of the indoor air temperature induction.

[0003] A Chinese patent with the publication number of CN220402079U discloses an open-type temperature controller. By setting a maintenance port on the surface of the temperature controller and an installation port on the side, the display screen can have the effect of being viewed from the side. At the same time, the opening of the maintenance port is beneficial to the maintenance of the inside of the temperature controller. The open structure makes the use of the temperature controller convenient for maintenance and avoids the reduction of the service life caused by dust adhering to the internal components of the temperature controller.

[0004] The above-mentioned prior art solutions have the following defects: There is no filter that is easy to disassemble at the heat dissipation mesh port, resulting in dust accumulation on the surface of the heat dissipation mesh port. If tools such as brushes are used to brush it off, the dust will be raised under the action of the brush and easily pass through the mesh port into the inside of the temperature controller, causing adverse effects on the internal components and other external electrical components, and the long-term accumulation of dust at the heat dissipation mesh port will affect the heat dissipation of the temperature controller and shorten the service life of the temperature controller.

[0005] Therefore, an open-type temperature controller is proposed. Summary of the Utility Model

[0025] As Figures 1 to 3 shown, an open-type temperature controller includes a protection box 1. An external temperature control component 2 is provided on the surface of the protection box 1. Heat dissipation holes 3 are opened on the left and right side walls of the protection box 1. A cover plate 4 is installed on the top surface of the protection box 1. Outer plug filters 5 for covering the heat dissipation holes 3 are fixedly installed on both sides of the bottom surface of the cover plate 4. The outer plug filters 5 are slidably arranged in contact with the side surface of the protection box 1. A sealing block 8 is fixedly installed on the bottom surface of the cover plate 4. The sealing block 8 is slidably arranged in contact with the inner side surface of the protection box 1. Telescopic plug components 9 are provided on the front and rear side surfaces of the sealing block 8. Jacks 10 are opened on the front and rear side walls of the protection box 1. The telescopic plug components 9 are slidably inserted into the jacks 10. A telescopic control component 11 for driving the telescopic movement of the telescopic plug components 9 is provided on the surfaces of the cover plate 4 and the sealing block 8.

[0026] More specifically, the telescopic control component 11 drives the telescopic bolt component 9 to expand and contract. When the telescopic bolt component 9 slides and inserts into the jack 10, the cover plate 4 is reliably fixed, so that the externally inserted filter screen 5 reliably adheres to the surface of the heat dissipation holes 3 to filter dust, impurities, etc. When it is necessary to regularly overhaul the components inside the protection box 1 or clean the dust and impurities on the surface of the externally inserted filter screen 5, by rotating the telescopic control component 11, the telescopic bolt component 9 can be driven to retract into the sealing block 8, and the telescopic bolt component 9 slips out of the jack 10. At this time, the cover plate 4 can be quickly removed, and thus the externally inserted filter screen 5 fixedly installed on the bottom surface of the cover plate 4 can be removed together, and the externally inserted filter screen 5 can be quickly and independently cleaned of dust, avoiding the adverse effects of dust falling back on the internal and external electronic components of the protection box 1. Moreover, the structures such as the externally inserted filter screen 5, the telescopic bolt component 9, and the jack 10 provided on the surface of the cover plate 4 are all non-electric structures. Therefore, the externally inserted filter screen 5 can be cleaned by flushing, which has higher cleaning efficiency.

[0027] The external temperature control component 2 includes a window 201, a manual setting panel 202, a transmission line 203, and a sensing probe 204. The window 201 and the manual setting panel 202 are fixedly installed on the front surface of the protection box 1, the transmission line 203 is fixedly installed on the bottom surface of the protection box 1, and the sensing probe 204 is fixedly installed at one end of the transmission line 203 away from the protection box 1.

[0028] Specifically, relevant setting and detection data are read through the window 201, relevant data for temperature control are set through the manual setting panel 202, and the detection of the ambient temperature is completed by the cooperation of the transmission line 203, the sensing probe 204, and other components inside the protection box 1.

[0029] The externally inserted filter screen 5 includes a screen frame 501. The two screen frames 501 are respectively fixedly installed on the left and right sides of the bottom surface of the cover plate 4. The screen frame 501 is slidably arranged in contact with the side surface of the protection box 1, and a dust filter screen 502 is fixedly installed on the inner surface of the inner circle of the screen frame 501.

[0030] Specifically, the screen frame 501 is in contact with the left and right side surfaces of the protection box 1 to prevent dust from entering the protection box 1 through the gap between the screen frame 501 and the protection box 1 and passing through the heat dissipation holes 3, so that the dust filter screen 502 adheres to the surface of the heat dissipation holes 3, thereby effectively filtering dust.

[0031] U-shaped support plates 6 are fixedly installed on the left and right side surfaces of the protection box 1. Slots 7 are formed on the inner surface of the inner circle of the U-shaped support plates 6, and the screen frame 501 is slidably inserted into the inner wall surface of the slots 7.

[0032] Specifically, the periphery of the screen stretching frame 501 is wrapped by the U-shaped support plate 6. On the one hand, the screen stretching frame 501 attached to the side surface of the protection box 1 is limited, ensuring the stable and reliable attachment of the screen stretching frame 501 to the protection box 1. On the other hand, the wrapping of the U-shaped support plate 6 further prevents dust from entering the interior of the protection box 1 from the joint between the screen stretching frame 501 and the protection box 1, having a better dust-proof effect.

[0033] The telescopic bolt assembly 9 includes limit sliding grooves 901, and the two limit sliding grooves 901 are respectively opened on the front and rear side surfaces of the sealing block 8. A limit slider 903 is slidably installed on the inner wall surface of the limit sliding groove 901. A threaded rod 902 driven by a telescopic control assembly 11 is rotatably arranged on the inner wall surface of the limit sliding groove 901. The limit slider 903 is threadedly installed on the surface of the threaded rod 902. An insertion block 904 is fixedly installed on the surface of the limit slider 903. The two insertion blocks 904 are respectively slidably inserted into the front and rear side surfaces of the sealing block 8. The insertion block 904 is slidably inserted into the inner wall surface of the insertion hole 10. The front and rear two telescopic bolt assemblies 9 are symmetrically arranged.

[0034] Specifically, the threaded rod 902 is driven to rotate through the insertion hole 10, so that the limit slider 903, which is threadedly installed on the surface of the threaded rod 902 and slidably installed on the inner wall surface of the limit sliding groove 901, slides back and forth, thereby driving the insertion block 904 fixedly installed on the surface of the limit slider 903 to stretch out and retract from the surface of the sealing block 8. When the insertion blocks 904 on the front and rear sides synchronously extend, they can be slidably inserted into the insertion hole 10 to realize the reliable installation and fixation of the cover plate 4. When the insertion blocks 904 on the front and rear sides synchronously retract, the cover plate 4 can be removed from the top surface of the protection box 1, so that the external insertion filter screen 5 can be removed for cleaning.

[0035] The telescopic control assembly 11 includes a part cavity 111, and the part cavity 111 is opened inside the sealing block 8. A worm 112 is rotatably installed on the inner wall surface of the part cavity 111. The worm 112 penetrates through the top surface of the cover plate 4 and is rotatably arranged. A knob 113 is fixedly installed on the top surface of the worm 112. A worm gear 114 is meshed on the surface of the knob 113. Rotating rods 115 are fixedly installed on the front and rear side surfaces of the worm gear 114. The two rotating rods 115 are respectively rotatably installed on the front and rear inner wall surfaces of the part cavity 111. The rotating rod 115 penetrates through the inner wall surface of the limit sliding groove 901 and is rotatably arranged and fixedly connected to the surface of the threaded rod 902.

[0036] Specifically, rotating the knob 113 drives the worm 112 to rotate. The worm 112 drives the worm gear 114 meshed on its surface to rotate, and further drives the two rotating rods 115 fixedly installed on the front and rear side surfaces of the worm gear 114 to rotate synchronously. Finally, the two symmetric threaded rods 902 fixedly connected to the rotating rods 115 rotate synchronously, realizing the synchronous drive of the front and rear two telescopic bolt assemblies 9, so that the front and rear two insertion blocks 904 stretch and retract synchronously.

[0037] In summary: By reliably attaching the external filter screen 5 to the surface of the heat dissipation holes 3, dust, impurities, etc. can be filtered out. By rotating the telescopic control component 11, the telescopic plug component 9 can be driven to retract into the sealing block 8, and the telescopic plug component 9 slips out of the jack 10. At this time, the cover plate 4 can be quickly removed, and thus the external filter screen 5 fixedly installed on the bottom surface of the cover plate 4 can be removed together, enabling quick independent dust cleaning of the external filter screen 5, avoiding adverse effects on the internal and external electronic components of the protection box 1 caused by the fall of floating dust, and the structures such as the external filter screen 5, telescopic plug component 9, and jack 10 provided on the surface of the cover plate 4 are all non-powered structures. Therefore, the external filter screen 5 can be cleaned by flushing, with higher cleaning efficiency.
