Abstract

The utility model discloses an electric tea tray, comprising a body and a control circuit arranged inside the body, wherein the body is provided with a heat preserving tray, a heating element and a temperature probe are arranged at the lower part of the heat preserving tray, the body is provided with an infrared sensor for detecting whether a kettle body is arranged on the heat preserving tray, and the infrared sensor is connected with the control circuit. The heat preserving tray is provided with the infrared sensor, the temperature probe is arranged at the lower part of the heat preserving tray, and the infrared sensor is accurate in sensing and is not easily damaged; therefore, the electric tea tray is durable, has reliable use and can be widely applied to various occasions such as a family, an office and a teahouse.

Description

The electricity tea tray

Technical field

The utility model relates to a kind of electric tea tray.

Background technology

Present electric tea tray, push switch normally is installed on hot plate, and when teapot is placed on the top of hot plate, then this push switch is connected, drive heater element work by control circuit, thereby teapot is heated, still, when long-term use, push switch damages easily, it is not high then to control sensitivity, is not that the situation that dry combustion method occurs is exactly that heater element can't be worked, and it is unreliable to use.

In addition, the indication of the duty of existing electric tea tray is unintelligible, when the user is far away apart from electric tea tray, often can't know that this electricity tea tray whether in work, uses inconvenient.

Summary of the invention

In order to solve the above problems, the purpose of this utility model is to provide a kind of service-strong electricity tea tray.

The technical scheme that the invention for solving the technical problem adopted is:

The electricity tea tray, comprise main body and be installed in the interior control circuit of main body, hot plate is installed on the main body, heater members and temp probe are installed below hot plate, whether have kettle body be placed on infrared inductor hot plate on, infrared inductor is connected with control circuit if on described main body, being provided with detection.

Further, as preferred implementation, the position that corresponding teapot holds on main body is embedded with relay indicating light, and relay indicating light is connected to control circuit.Like this, when the electricity tea tray uses, as heater members work, then indicator lamp is lighted, and because indicator lamp is to be inlaid on the hot plate that holds teapot, under the situation of the teapot that uses the bottom and the light-permeable of leaning to one side, light can outwards spread out of by the teapot kettle body that fills water, be that light source is the kettle body, luminous volume is big, is convenient to observe.

The beneficial effects of the utility model are: owing to be provided with infrared inductor on main body, when having detected kettle, the infrared ray inductor is placed on the hot plate, it can output signal to control circuit, whether work by control circuit control heater members, accurate, the difficult infringement of infrared induction device induction, thus above-mentioned electric tea tray is durable for a long time, it is reliable to use.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is the structural representation of the utility model embodiment;

Fig. 2 is a sectional structure schematic diagram of the present utility model.

The specific embodiment

With reference to Fig. 1, Fig. 2, electric tea tray of the present utility model, comprise main body 1 and the control circuit 10 that is installed in the main body 1, hot plate 2 is installed on the main body 1, heater members 3 and temp probe 4 are installed below hot plate 2, whether have kettle body be placed on infrared inductor 5 hot plate on, infrared inductor 5 is connected with control circuit 10 if on described main body 1, being provided with detection.

Wherein, whether infrared inductor can be installed in any on the main body and can detect and have the teapot body to be placed on the position on the hot plate, certainly, its optimal way is, for easy for installation, detect accurately, described infrared inductor 5 is installed on the hot plate 2, specifically can be mounted on the middle position of hot plate 2.

Further, the position that corresponding teapot holds on main body 1 is embedded with relay indicating light 6, and relay indicating light 6 is connected to control circuit 10, is used for indicating the heating of whether working of this electricity tea tray to the user.Wherein, as preferred implementation, described relay indicating light 6 is three LED lamps on the main body 1 that is evenly distributed on hot plate 2 peripheries.Make that the light that is radiated on the kettle body is more sufficient, people are easier to observe from afar.

In addition, described hot plate 2 is a metal dish, and heater members 3 is close to the bottom of metal dish, and the top of temp probe 4 is connected to the bottom of metal dish.Wherein, this heater members 3 can be the PTC heat-generating pipe that is close to hot plate 2 bottoms.

Further, described main body 1 be provided with control circuit 10 be connected, in establish the LCD display 7 of background light source, make that decorative effect is better, be more convenient for watching.

In addition, control circuit 10 of the present utility model can be provided with key etc. by power circuit, main control chip, heater members drive circuit, infrared detection circuit, temperature sensing circuit and parameter and form, these physical circuits are current techiques, enumerate no longer one by one at this, as long as it can realize infrared detection, temperature detection, driving control, indicated number etc.

Certainly, the invention is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
