Description

Technical Field

[0001] The present invention belongs to the technical field of household appliances, and more specifically, relates to a key structure, a wired controller, and an air conditioner. Background Art

[0002] Central air conditioners usually adopt two methods, namely a remote controller or a wired controller, to achieve control, and each has its own advantages when controlling the central air conditioner.

[0003] For the wired controller method, a knob method or a combination of a knob and key presses is usually adopted, such as the nest thermostat. The knob is used to select various parameters, and the press is used to confirm the selected parameters, without a cancel key operation. When it is necessary to return to the upper-level menu or cancel an operation, only this operation item can also be used as an optional parameter. The parameter is selected by rotating the knob and the key is pressed to confirm to return to the upper-level menu or cancel the operation.

[0004] Selecting the "return / cancel" parameter by rotating the knob is prone to misoperation. For example, when a user wants to set the heating mode and rotates to the heating mode, and then wants to cancel this operation, they can only rotate to "return / cancel" and confirm the operation. However, when the operation is not careful, it is easy to rotate to other modes and mistake them for the "return / cancel" parameter. At this time, pressing the key is equivalent to confirming the setting to this mode instead of canceling the setting, thus causing misoperation. Summary of the Invention

[0005] The purpose of the present invention is to provide a key structure, a wired controller, and an air conditioner to solve the problem in the prior art that misoperation is easily caused when confirming and canceling settings.

[0006] To achieve the above purpose, the technical solution adopted by the present invention is: providing a key structure, including a rotating ring and a pressing component. The pressing component is sleeved inside the rotating ring. The pressing component includes a first key for performing a confirmation operation; the pressing component further includes a second key for performing an operation opposite to the confirmation operation, that is, performing a return / cancel operation.

[0007] Further, the pressing component includes a panel, a key board, and a bottom plate. The key board is located between the panel and the bottom plate. The first key is arranged on one side of the key board, and the second key is arranged on the other side of the key board. Contact points for contacting the first key and the second key are respectively arranged on the panel and the bottom plate.

[0008] Further, the pressing component includes a panel, a key board, and a bottom board. The key board is located between the panel and the bottom board. The first key and the second key are both arranged on the same surface of the key board, and a certain distance is set between the first key and the second key. Contacts corresponding to the first key and the second key are arranged on the panel; or, contacts corresponding to the first key and the second key are arranged on the bottom board.

[0009] Further, between the key board and the panel; and / or, between the key board and the bottom board; a reset component for driving the key board to reset is provided.

[0010] Further, the reset component includes at least one spring.

[0011] Further, the springs on the same side of the key board are evenly distributed.

[0012] Further, the springs on both sides of the key board are symmetrically distributed with respect to the key board.

[0013] Further, support columns for connecting the springs are arranged on the panel, the key board and / or the bottom board.

[0014] Further, a groove for accommodating the key board is formed on the inner wall of the rotating ring.

[0015] Another object of the present invention is to provide a remote controller, and the remote controller includes the above-mentioned key structure.

[0016] Another object of the present invention is to provide an air conditioner, and the air conditioner includes the above-mentioned remote controller.

[0017] The beneficial effect of the key structure provided by the present invention is that: compared with the prior art, on the basis of the original first key for performing confirmation operations, the present invention newly adds a second key. Previously, after selecting through the rotating ring, the confirmation operation was performed through the first key. By rotating the rotating ring to select the corresponding menu to select the required mode and perform return / cancel operations. The present invention uses the second key to replace the method of rotating the rotating ring to perform return / cancel operations, so that the first key and the second key have clear division of labor during execution, reducing the situation that the first key is easily pressed after performing the return / cancel operation by rotating the rotating ring, and thus easily generating misoperations. At the same time, it reduces the workload of rotating the rotating ring, saves time, is easy to operate, and conforms to humanized and industrialized designs. Description of the Drawings

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0027] Please refer to Figures 1 to 3, the key structure provided by the embodiments of the present invention will now be described. The key structure includes a rotating ring 2 and a pressing component 1, and the pressing component 1 is sleeved inside the rotating ring 2. The same as the prior art is that the pressing component 1 includes a first key 101 for performing a confirmation operation. When the user needs to perform a confirmation operation, the pressing component 1 is pressed to make the first key 101 connect to its corresponding circuit, so that the steps of the confirmation operation can be executed, which will not be elaborated here. In addition, the difference from the prior art is that the pressing component 1 further includes a second key 102, and the second key 102 is used to perform a return / cancel operation. There are usually many selectable parameters in the menu of the remote controller. When the user performs a return / cancel operation, the rotating ring 2 is usually rotated multiple circles and then the first key is pressed to confirm the cancellation, and the operation is relatively complicated. In addition, it is easy to cause misoperation when selecting through the rotating ring 2 and then confirming and executing the return / cancel operation through the first key (which has been mentioned in the background technology and will not be elaborated here). Therefore, previously, after selecting through the rotating ring 2 and then performing a confirmation operation through the first key 101, by rotating the rotating ring 2 to select the corresponding menu, when it is found that cancellation is needed, the rotating ring 2 is rotated to the return / cancel item, and then the first key 101 is pressed to perform the return / cancel operation. The present invention uses the second key 102 to replace the method of first selecting and then performing the return / cancel operation by rotating the rotating ring 2, so that the first key 101 and the second key 102 have clear division of labor during execution, and reduces the situation that the first key 101 is easily pressed after the return / cancel operation is performed by rotating the rotating ring 2, which is prone to misoperation.

[0028] Compared with the prior art, the key structure provided by the present invention adds a second key 102 on the basis of the original first key 101 for performing a confirmation operation. Previously, after selecting through the rotating ring 2 and then performing a confirmation operation through the first key 101, by rotating the rotating ring 2 to select the corresponding menu to select the required mode and perform the return / cancel operation. The present invention uses the second key 102 to replace the method of performing the return / cancel operation by rotating the rotating ring 2, so that the first key 101 and the second key 102 have clear division of labor during execution, reduces the probability of misoperation that is easily caused by the first key 101 being pressed after the return / cancel operation is performed by rotating the rotating ring 2, and at the same time reduces the workload of originally rotating the rotating ring 2, saves time, is easy to operate, and conforms to the humanized and industrialized design.

[0029] Further, please refer to Figures 1 to 3, as a specific embodiment of the key structure provided by the present invention, the pressing assembly 1 includes a panel 103, a key board 104, and a bottom plate 105 (both are parts of the remote controller). Among them, the key board 104 and the panel 103 are respectively located on both sides of the key board 104. The first key 101 is arranged on one side of the key board 104, and the second key 102 is arranged on the other side of the key board 104. Contacts 3 (shown by reference numerals 3a and 3b in the figure) corresponding to and used for conduction are respectively arranged on the panel 103 and the bottom plate 105 for the first key 101 and the second key 102. When performing a confirmation operation or a return / cancel operation, the moving directions of the first key 101 and the second key 102 are opposite, which greatly reduces the possibility of accidental operation. Moreover, when there is a situation where you want to reselect after making a selection, in the prior art, the return / cancel operation is selected in the menu by rotating the rotating ring 2, which is time-consuming. However, in the present invention, the return / cancel operation is realized by pressing the second key 102 to connect the corresponding circuit, without the need to rotate the rotating ring 2 too much for adjustment, reducing the complexity of the operation, making it more convenient for the user to operate, and improving the user experience.

[0030] In addition, the above-mentioned is only a specific embodiment of the pressing assembly 1. The first key 101 and the second key 102 can also be arranged on the same surface of the key board 104, with a certain distance between the positions of the first key 101 and the second key 102 (the specific distance can be determined according to actual design needs), and the first key 101 and the second key 102 can be distinguished or marked. Correspondingly, the contacts 3 corresponding to the first key 101 and the second key 102 are also arranged on the same side. Of course, other ways of using keys to replace the rotating ring 2 to perform the return / cancel operation, as long as they are the same in essence as this solution, are all designs the same as this solution, and will not be listed and elaborated one by one here.

[0031] Preferably, please refer to Figure 1 , after pressing the panel 103 and the key board 104, the key board 104 needs to return to its original position for subsequent pressing actions. Therefore, a reset component needs to be installed to realize the reset of the key board 104. The spring 4 is a relatively common and practical reset element, so the reset component is selected as the spring 4 here. After the key board 104 is pressed, the spring 4 bounces the key board 104 back to the initial position.

[0032] Specifically, as mentioned above, the key panel 104 is located between the panel 103 and the bottom plate 105. There are embodiments in which the first key 101 and the second key 102 are respectively arranged on both sides of the key panel 104, and embodiments in which both the first key 101 and the second key 102 are arranged on the same side of the key panel 104 (hereinafter referred to as Embodiment 1 and Embodiment 2 for short).

[0033] Regarding Embodiment 1: The first key 101 and the second key 102 are respectively arranged at the center positions of both sides of the key panel 104. A plurality of springs 4 are arranged on both sides of the key panel 104. In order to make the force more evenly distributed during the pressing of the key panel 104 and the panel 103, and make the contact between the first key 101, the second key 102 and the contact point 3 more sufficient, the springs 4 are evenly arranged along the circumferential direction of the key panel 104. The number of springs 4 on the same side of the key panel 104 is preferably an even number, for example, 4, 6, 8, etc. can be selected.

[0034] In addition, since a plurality of springs 4 are arranged on both sides of the key panel 104, therefore, on the premise of ensuring that the springs 4 mentioned above are evenly arranged along the circumferential direction of the key panel 104, it is also necessary to design and limit the springs 4 on both sides of the key panel 104. The springs 4 on both sides of the key panel 104 can be set to be symmetrical about the key panel 104. Or the springs 4 on both sides of the key panel 104 can also be respectively designed to be evenly distributed along the circumferential direction of one side of the key panel 104 where they are located, and one spring 4 on one side is located between two springs 4 on the other side. Preferably, the number of springs 4 arranged on both sides of the key panel 104 is the same. One spring 4 on one side is arranged between two springs 4 on the other side, and one spring 4 on one side evenly divides the central angle between two springs 4 on the other side is the best.

[0035] For Embodiment 2 (not shown in the figure): Both the first button 101 and the second button 102 are located on the same side of the button board 104, and the first button 101 and the second button 102 need to be set at a certain distance apart. Therefore, when the spring 4 is arranged on the side with the first button 101 and the second button 102, the spring 4 needs to surround the first button 101 and the second button 102, and it is necessary to ensure that whether the first button 101 or the second button 102 is pressed, the first button 101, the second button 102 and their corresponding contacts 3 can make sufficient contact and receive uniform force. Of course, the specific setting needs to be determined according to the shape of the button board 104 and the designed positions of the first button 101 and the second button 102. For example, if the shape of the button board 104 is still circular, the spring 4 can be arranged on the button board 104 to form the following shape after arrangement. From the perspective of looking down at the button board 104, the arrangement of the spring 4 is in the shape of the number "8", and the first button 101 and the second button 102 are respectively arranged at the two circles of the "8". Of course, the specific setting method still needs to be determined according to the shape of the button board 104 and the specific positions of the first button 101 and the second button 102 on the button board 104.

[0036] In addition, for Embodiment 1: Since the pressing directions of the second button 102 and the first button 101 are opposite, when performing the return / cancel operation, the button board 104 needs to contact the contact 3 corresponding to the second button 102 (in this solution, the contact 3 corresponding to the second button 102 is arranged on the panel 103). Here, since the rotating ring 2 is sleeved on the bottom plate 105, the button board 104 and the panel 103, the movement of the button board 104 towards the panel 103 is converted into the movement of the rotating ring 2. A groove 6 for accommodating the edge of the button board 104 is opened on the inner wall of the rotating ring 2 (see Figure 2 for the connection relationship), so that the rotating ring 2 drives the button board 104 to move towards the panel 103 during the movement. After the button board 104 completes the movement of driving the first button 101 or the second button 102, the spring 4 mentioned above will apply force to the button board 104 and the panel 103 to reset the button board 104 and the panel 103. The button board 104 will drive the rotating ring 2 to reset during the reset process.

[0037] Preferably, please refer to Figure 1 and Figure 3 As a specific implementation manner of the button structure provided by the present invention, support columns 5 are arranged at the connection positions of the spring 4 with the panel 103, the bottom plate 105 and the button board 104 to fixedly connect the spring 4 with the panel 103, the bottom plate 105 and the button board 104, so that the connection between the spring 4 and the panel 103, the bottom plate 105 and the button board 104 is more firm.

[0038] Please refer to Figures 1 to 4, the present invention also provides a remote controller, which includes the above-mentioned button structure. The remote controller is usually installed on the wall 7, and the previously mentioned bottom plate 105, button plate 104 and panel 103 all belong to a part of the remote controller.

[0039] The present invention also provides an air conditioner, and the above-mentioned air conditioner includes the above-mentioned remote controller.

[0040] The following is a specific description of the working process of the rotary remote controller and Embodiment 1. The button plate 104 contains the control main board circuit of the entire remote controller, including a main control MCU, a button circuit, a communication circuit, and a liquid crystal display circuit of the panel 103, etc. Buttons are installed at the centers of both sides of the button plate 104. The first button 101 and the second button 102, combined with the contacts 3 on the panel 103 and the bottom plate 105, can realize the two-way pressing of the remote controller, that is, pressing (the first button 101) and pulling and pressing (the second button 102) operations. The panel 103 is equipped with a liquid crystal, which can display various states and functions of the remote controller. The support column 5 and the spring 4 form the button rebound structure of the entire rotary remote controller, enabling the remote controller to quickly bounce back to the balanced state after pressing the button. Among them, one end of the spring 4 is fixed to the thick end of the support column 5, and the other end is fixed to the button plate 104. The rotating ring 2 can be used to realize the operations of pressing and pulling and pressing the button, and various parameter selections can also be realized when the rotating ring 2 is rotated.

[0041] The present invention sets various parameters by rotating the outer ring rotating ring 2, and then confirms or cancels the parameter setting by pressing or pulling and pressing the button. For example, in the state where the set temperature is 18 degrees, if it is necessary to set the set temperature to 26 degrees, then rotate the outer ring rotating ring 2 to 26 degrees, and then gently hold the outer ring rotating ring 2 and press it towards the bottom plate 105. Combining with the contact 3 on the bottom plate 105, the button on the button plate 104 facing the bottom plate 105 can be triggered. When the MCU detects the trigger of this button, it is considered that the setting is confirmed (the temperature is set to 26 degrees). When the user rotates the outer ring rotating ring 2 to 26 degrees and then does not want to change the set temperature to 26 degrees and needs to cancel the operation or return to the upper-level menu, the outer ring rotating ring 2 can be gently held and pulled and pressed towards the panel 103. Combining with the button contact 3 on the panel 103, the button on the button plate 104 facing the panel 103 side can be triggered. When the MCU detects the trigger of this button, it is considered that the setting is cancelled or the upper-level menu is returned (the set temperature remains 18 degrees).

[0042] The bottom plate 105 and the panel 103 are fixed. The keypad 104 can only move towards or away from the panel 103 and the bottom plate 105, and cannot rotate. The rotation selection operation is mainly achieved through the outer ring rotating circle 2. The keypad 104 and the rotating circle 2 perform rotational sliding, pressing, and pulling and pressing sliding by using the groove 6 between them. The groove 6 can limit the keypad 104 in a certain position. When the rotating circle 2 is pressed downwards, the groove 6 restricts the keypad 104 to be pressed downwards as well, thereby triggering the button. When the keypad 104 is pressed downwards, the spring 4 (only a specific embodiment) sleeved in the 4 support columns 5 is also compressed. When the hand releases the rotating circle 2, the spring 4 is no longer stressed and quickly returns to the original equilibrium state, releasing the button. Similarly, the pulling and pressing button operation can be obtained.

[0043] The 4 springs 4 on each side of the keypad 104 are evenly distributed in 4 directions of the keypad 104, which can keep the whole button structure balanced whether it is pressed or pulled, and there will be no side skew phenomenon.

[0044] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
