Description

Technical Field

[0001] The present invention relates to the technical field of air conditioning, and in particular to a switch device and an air conditioner. Background Art

[0002] In existing air conditioning equipment products, a micro switch is provided at a detection position such as a connection detection between a middle frame and an electric control box seat. When the detected condition reaches a preset condition, the contact pressure portion of the micro switch is contacted and the micro switch sends a corresponding signal in response.

[0003] In the prior art, the micro switch on the air conditioner electric control box is used to detect whether the middle frame is removed. Generally speaking, the middle frame directly presses vertically downward on the button of the micro switch. Since the manual installation of the middle frame will have a large force, it is easy to cause overpressure to damage the button. Overpressure will cause internal damage to the switch or poor contact, which will lead to program misjudgment and action failure. On the other hand, the button of the micro switch is relatively small, and the depth tolerance of the micro switch and the middle frame is relatively large, so the button cannot be pressed. Summary of the invention

[0004] In view of this, the present invention aims to provide a switch device and an air conditioner, by providing a force-conducting structure to rotate a button that is in vertical contact with the middle frame to the side, so that the force directly pressing vertically downward on the button is converted into a lateral extrusion force.

[0005] To achieve the above object, the technical solution of the present invention is achieved as follows:

[0006] A switch device comprises a switch box and a guide column, wherein the guide column extends into the switch box, a switch body is arranged in the switch box, a button is arranged on the switch body, one end of the button is fixedly connected to the switch body, and the other end of the button contacts a spring, the button and the guide column are arranged at an angle, the contact of the spring and the guide column can slide relative to each other, the spring can be selectively squeezed, and the button can be squeezed by the spring.

[0007] The guide post can slide and / or return to its original position under the action of an external force. A first groove is provided on the guide post, and the contact of the spring sheet can extend into or slide out of the first groove during the sliding process of the guide post.

[0008] Furthermore, the first groove arranged on the guide column is a long-stroke groove, and a first boss is arranged on the long-stroke groove, so that the contact of the spring piece can slide from the long-stroke groove at the bottom of the first boss to the long-stroke groove at the top of the first boss when the guide column slides.

[0009] Furthermore, the angle between the button and the guide column ranges from 45° to 135°.

[0010] Furthermore, the switch box includes an upper limit plate and a lower limit plate, the guide column passes through the upper limit plate and is limited by the lower limit plate, and the first groove on the guide column can slide or return to its original position between the upper limit plate and the lower limit plate as the guide column moves.

[0011] Furthermore, the upper limit plate, the lower limit plate and the guide column are vertically arranged.

[0012] Furthermore, the guide column includes a limit column and a limit portion, the diameter of the limit column is smaller than the diameter of the limit portion, the first groove is arranged on the limit portion, and the spring is sleeved on the outer side of the limit column.

[0013] Furthermore, the lower end of the limit column extends out of the lower limit plate, and the spring is compressed or restored between the limit portion and the lower limit plate.

[0014] Furthermore, the contact has a U-shaped structure.

[0015] Compared with the prior art, the switch device of the present invention has the following advantages:

[0016] (1) The present invention discloses a switch device, which has a button and a guide column arranged at an angle. When the guide column is not subjected to external force, the contact of the spring is arranged in the first groove of the guide column. At this time, the spring is in a relaxed state and the button is not subjected to force. When the guide column is subjected to external force and slides toward the inside of the switch box, the contact of the spring slides out of the first groove. At this time, the spring is squeezed, and the contact exerts a lateral force on the spring from the first groove to the plane, thereby compressing the button to achieve the function of transmitting signals and realizing the control of the switch. The switch device described in the present invention changes the force direction of the switch button by setting a structure for conducting force, thereby avoiding the problem that the spring of the switch is easily in failure due to being in a compressed state during use, and also avoiding the occurrence of overpressure due to excessive external force during use.

[0017] (2) The switch device described in the present invention solves the problem of abnormal friction noise generated by the guide column of the switch when sliding, and also avoids the problem of the spring piece failing due to long-term use, thereby further improving the reliability and life of the switch described in the present invention.

[0018] (3) In the switch device described in the present invention, the guide column has a certain length, which increases the movable stroke of the external force applying device and solves the problem that the button is difficult to press due to large matching tolerance.

[0019] (4) The switch device described in the present invention has an ingenious structure, simple connection, and is easy to produce and assemble, which greatly improves the convenience and reliability of the switch.

[0020] Another object of the present invention is to provide an air conditioner, comprising a base device, a middle frame and the switch device as described above, wherein the middle frame can squeeze the guide column to slide in the switch box during assembly with the base device.

[0034] The invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0035] Embodiment 1, as Figures 1 to 3 As shown, the present invention discloses a switch device, including a switch box 3 and a guide column 4, wherein the guide column 4 extends into the interior of the switch box 3, a switch body 7 is arranged in the switch box 3, a button 8 is arranged on one side of the switch body 7, the other end of the button 8 contacts with a spring 9, the button 8 is arranged at an angle with the guide column 4, the guide column 4 can slide and / or return to its original position under the action of an external force, a first groove 12 is arranged on the guide column 4, a contact 10 of the spring 9 can extend into or slide out of the first groove 12 during the sliding process of the guide column 4, and the button 8 can be squeezed by the spring 9.

[0036] The present invention discloses a switch device, which has a button and a guide column arranged at an angle. When the guide column is not subjected to external force, the contact of the spring is arranged in the first groove of the guide column. At this time, the spring is in a relaxed state and the button is not subjected to force. When the guide column is subjected to external force and slides toward the inside of the switch box, the contact of the spring slides out of the first groove. At this time, the spring is squeezed, and the contact from the first groove to the plane will give the spring a lateral force, thereby compressing the button, achieving the effect of transmitting signals and realizing the control of the switch. The switch device of the present invention changes the force direction of the switch button by setting a structure for conducting force, thereby avoiding the problem that the spring of the switch is easily ineffective due to being in a compressed state during use, and also avoiding the occurrence of overpressure due to excessive external force during use.

[0037] Preferably, as a preferred embodiment of the present invention, the angle between the button 8 and the guide column 4 is in the range of 45° to 135°, preferably 90°. This setting further discloses the setting relationship between the button and the guide column, ensures the reliability of the guide column acting on the button during the sliding process under the action of external force, and further reduces the probability that the spring sheet cannot contact the button or the spring sheet over-presses the button.

[0038] Preferably, as a preferred embodiment of the present invention, the switch box 3 includes an upper limit plate 5 and a lower limit plate 6, the guide post 4 passes through the upper limit plate 5 and is limited by the lower limit plate 6, and the first groove 12 on the guide post 4 can slide or return to its original position between the upper limit plate 5 and the lower limit plate 6 as the guide post 4 moves. This setting discloses a sliding and limiting method of the guide post in the switch box. As an example of the present invention, the upper limit plate, the lower limit plate and the guide post are vertically arranged.

[0039] Further, as a preferred embodiment of the present invention, the guide post 4 is provided with a spring 14 at one end close to the lower limit plate 6, and the spring 14 can be compressed during the sliding process of the guide post 4. This arrangement discloses a specific structure in which the guide post can be compressed or restored to its original position under the action of an external force, which has a simple structure, low cost, is easy to produce and assemble, and has good reliability.

[0040] Embodiment 2, as Figures 1-2 As shown in 4-5, the present invention also discloses another switch device, in which the first groove 12 is set on the guide column 4 as a long-stroke groove, and the first boss 11 is set on the long-stroke groove. When the guide column 4 slides, the contact 10 of the spring 9 can slide from the long-stroke groove at the bottom of the first boss 11 to the long-stroke groove at the top of the first boss 11. The other structures are the same as those in Example 1. The structure further optimizes the structure of the guide column. When the guide column slides downward, the contact of the spring slides from the lower end of the long-stroke groove to the first boss, and the spring presses the button to transmit information. When the contact of the spring slides from the first boss to the upper end of the long-stroke groove, the button pops up, and the contact of the spring does not contact the upper end of the long-stroke groove. The spring is in a relaxed state and is not subjected to force. In this process, the button will transmit a signal up and down to detect that the middle frame has been installed. When the external force is cancelled, the spring under the guide column will bounce the guide column, and the button will transmit a signal up and down in this process to realize the detection of the switch.

[0041] This arrangement solves the problem of friction noise generated by the guide post of the switch when sliding, and also avoids the problem of the spring piece failing due to long-term use, thereby further improving the reliability and life of the switch of the present invention.

[0042] Preferably, as a preferred embodiment of the present invention, the guide column 4 includes a limit column 13 and a limit portion 20, the diameter of the limit column 13 is smaller than the diameter of the limit portion 20, the first groove 12 is arranged on the limit portion 20, and the spring 14 is sleeved on the outer side of the limit column 13. Specifically, the lower end of the limit column 13 extends out of the lower limit plate 6, and the spring 14 is compressed or restored between the limit portion 20 and the lower limit plate 6. This setting discloses a specific structure of the guide column and the spring assembly limit, which is reasonable in structure, easy to produce, and reliable in use.

[0043] Embodiment 3, the present invention further discloses an air conditioner, comprising a base device 2 and a middle frame 1, wherein the above-mentioned switch device is arranged on the base device 2, and the middle frame 1 can squeeze the guide column 4 to slide in the switch box 3 during the assembly process with the base device 2.

[0044] When the middle frame 1 is not installed, the contact 10 on the switch spring 9 is in the first groove 12 of the guide column 4, and the spring 9 is in a relaxed state and is not subjected to force. At this time, the contact 10 is in a U-shaped structure.

[0045] When the middle frame is pressed up, the guide column 4 moves downward under the vertical downward pressure of the middle frame 1, and the spring 14 under the guide column 4 is compressed. During the downward movement of the guide column, the U-shaped structure of the spring sheet will leave the first groove and be on the plane of the guide column. The U-shaped head will give a lateral force to the spring sheet from the first groove to the plane, so that the spring sheet can press the button to achieve the function of transmitting the signal.

[0046] During this process, the middle frame presses force on the guide column, squeezing the spring through the guide column to press the button.

[0047] Through this arrangement, the guide column has a certain length, the movable stroke of the middle frame is increased, and the problem that the button is not easy to press due to large matching tolerance is solved.

[0048] In addition, the force of the middle frame pressing directly on the button is transmitted as lateral force through the object, thus solving the problem of overpressure.

[0049] Furthermore, as a preferred embodiment of the present invention, the base device 2 includes an upper base 16 and a lower base 15 , and the upper base 16 is detachably fixedly connected to the lower base 15 .

[0050] Preferably, as a preferred embodiment of the present invention, an electric control box accommodating chamber 17 is provided on the upper base 16, and the electric control box accommodating chamber 17 is used to accommodate and fix the electric control box 18, and the switch device is provided between the electric control box 18 and the middle frame 1. This setting discloses a specific setting position of a micro switch on the air conditioner, and the setting ensures the convenience of switch setting and the reliability of use.

[0051] Furthermore, as a preferred embodiment of the present invention, a motor water baffle 19 is provided on the upper base 16, and the motor water baffle 19 limits the lateral direction of the switch box 3. This arrangement further ensures the reliability of the fixed limit of the switch inside the air conditioner, and ensures the normal use of the switch and the accuracy of detection.

[0052] The switch device of the present invention has an ingenious structure, simple connection, and is easy to produce and assemble, thereby greatly improving the convenience and reliability of the switch.

[0053] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
