A borderless thermostat

Abstract

The invention discloses a frameless temperature controller, which is mainly composed of a display control surface, a positioning structure, a middle frame and a first circuit board, the display control surface is fixed and covered on the middle frame by the positioning structure, and the first circuit board The board is located in the middle frame: the display control surface is composed of a light-transmitting board, the first key, the second key and the third key. The first key is located on the light-transmitting board, its shape is square, and its outer edge Outside the outer edge of the frame, its cantilever structure is an elastic arm structure; there is a button in the middle of the circuit board, and the top of the button touches the first button; the positioning structure is composed of 4 positioning shrapnels on the middle frame, and the positioning shrapnel is in contact with the first button. The grooves in the keys match; the light-transmitting plate is fixed on the middle frame below the first key, the second key and the third key are arranged at two corners under the light-transmitting plate, and the outer edges of the second key and the third key will be The outer edge of the middle frame is covered. The invention also includes a balance bar structure, the temperature controller of the invention is not easy to accumulate dust, the buttons are stable and in good contact, and the appearance is beautiful.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a temperature controller, especially a frameless temperature controller. Background technique [0002] Thermostat refers to a series of automatic control elements that physically deform inside the switch according to the temperature change of the working environment, thereby producing some special effects, and generating conduction or disconnection actions. It is also called a temperature control switch and a temperature protector. , Temperature controller, referred to as thermostat. Or the temperature is transmitted to the temperature controller through the temperature protector, and the temperature controller sends a switch command to control the operation of the equipment to achieve the ideal temperature and energy saving effect. Thermostats have a wide range of applications. According to different types of thermostats, they are used in many products such as home appliance...

Problems solved by technology

[0003] However, in the prior art, since most of the current thermostats have frames and the screens also have frames, the frames are not conducive to beautifying the appearance, have no visual impact, lack a sense of technology, and the gap between the frames and the buttons is easy to accumulate. Dust, causing the growth of bacteria, and even cause thermostat failure

In addition, it often happens that the keys are prone to dislocation, and some keys with large areas may also have poor contact, which affects the adjustment of the temperature.
