Description

A coffee table with a water tank water quantity detection mechanism

technical field

The invention relates to the technical field of furniture, in particular to a coffee table with a water tank detection mechanism.

Background technique

Existing tea tables for furniture have various structures and styles, but single functions, and are generally only used as furniture. However, with the continuous improvement of people's living standards, people are no longer satisfied with the single furniture function of tea tables, especially for people. Deeply influenced by the culture of making tea, tea sets have begun to enter thousands of households. Therefore, the tea table with the function of making tea has always been desired by people; however, limited by the heater and its volume, the coffee table with the function of making tea has not been There are found in the market.

Even if it is an ordinary tea set, its structure includes a tea tray body, the tea tray body is provided with a tea tray surface for holding (brewing) teapots and teacups, a sewage collection tank is arranged on the tea tray surface, and one side of the tea tray body is used as an electric heating device , the electric heating device is mostly composed of an induction cooker and an electromagnetically heated kettle body; when in use, people first pour tap water into the kettle body, then place the kettle body on the surface of the induction cooker to heat it to boiling, and finally, put the boiled water Pour into a teapot (brew tea) and serve.

The tea set with the above-mentioned traditional structure has the following deficiencies: (1) Due to the small size of the teapot, all the boiling water in the kettle cannot be poured into the teapot. A slight drop in temperature will affect the brewing of tea, and it cannot even be used as tea for drinking. Therefore, the excess boiling water in the kettle is often dumped, which wastes electricity; (2) Every time you make tea, you need to pour tap water into the kettle. Then place it on the surface of the induction cooker for heating, and finally pour boiling water into the teapot before you can make tea for drinking. On the other hand, it limits people's different choices of water sources.

For this reason, there are also some tea sets that use an instant electric heating device, that is, an instant heating device communicated with tap water or a water storage tank is set on the tea set, and an instant heating device communicated with the instant heating device is installed on the tea tray. Water faucet; when people make tea, they put the teapot into the boiling water faucet (at this time, the "instant heating device" is powered on), and then turn on the boiling water faucet, and the boiling water will flow out immediately, until the teapot is filled with boiling water, then turn off the boiling water faucet, the whole operation It is simple and convenient, and it can truly achieve the effect of how much boiling water is drunk and how much boiling water is boiled by the heater, without causing waste and saving electric energy.

However, the above-mentioned tea-making set with an instant electric heating device still has the following disadvantages: (1) In view of the water storage tank (or balance water tank) on the tea tray, it only serves to store water (or balance level), When the instant heater encounters water shortage in the water storage tank, if it fails to stop (heat) in time, the instant heater is easily damaged due to dry burning; (2) the existing instant heating device, Electric heating plates or electric heating tubes are mostly used for heating. This heating method has the disadvantages of low thermal efficiency and energy consumption.

The purpose of the present invention is achieved like this.

A tea table with a water volume detection mechanism, including a tea table and its feet, a water tap is installed on the tea table, and it is characterized in that a pipeline heater, a water tank and its water volume detection mechanism are also installed on the tea table, and the pipeline heater is installed There is a water inlet and a water outlet, the water inlet is connected to the water tank, and the water outlet is connected to the faucet through a pipe. The water quantity detection mechanism is set on the outer wall of the water tank or in the water tank, so as to control the glass coating electric heating by detecting the weight of the water tank or the water level in the water tank. prevent the water tank from running dry due to lack of water, and the pipe heater is an instant heater with high thermal efficiency and energy saving; the pipe heater uses glass-coated electric heating tubes, which are not easy to generate scale Moreover, the taste of boiled water is excellent, which can meet the requirements of making tea and drinking; moreover, the coefficient of thermal expansion of the glass-coated electric heating tube is relatively low, it is not easy to burst, and the safety of use is obviously higher.

The present invention can also be solved by adopting the following technical measures.

As a better implementation mode, an anti-dry thermostat and/or fuse is installed next to the pipeline heater, and the temperature controller and/or fuse are used to monitor the temperature of the outer surface of the heater. If there is no When the water flows through (dry burning), the temperature of the outer surface of the heater rises rapidly, and the thermostat and/or fuse cut off the power circuit of the heater to protect the heater and realize the function of preventing dry burning. Therefore, the thermostat and/or fuse The device cooperates with the water volume detection mechanism of the water tank to achieve double safety protection for the pipeline heater.

The water tank is provided with a leaking port, which communicates with the water inlet of the pipe heater, and a check valve is installed at the leaking port, so that when the water tank is disassembled, the check valve is automatically closed to prevent the water from flowing out; When the tea table top is on, the thimble on the tea table top opens the one-way valve, and at this time, the water in the water tank can flow out through the one-way valve.

The water quantity detection mechanism is a weight detection switch, the weight detection switch is electrically connected in series with the pipeline heater, and the weight detection switch is installed at the bottom of the water tank; during operation, as the water in the water tank decreases, the weight of the water tank decreases, and the water tank is set to The weight detection switch at the bottom of the water tank will monitor the change of the weight in the water tank. If the water in the inner tank drops to the set weight value, the weight detection switch will be disconnected, and the power supply of the pipeline heater will be cut off to protect the pipeline heater.

The water quantity detection mechanism is a weight detection switch, the weight detection switch and the pipeline heater are electrically connected in series, and the weight detection switch hooks the water tank in the form of a hook; The water in the inner tank decreases and the weight of the water tank decreases, so that the weight detection switch hooked on the top of the water tank monitors the change of the weight in the water tank. If the water in the inner tank drops to the set weight value, the weight detection switch is disconnected and the pipeline heater is cut off. The power supply also achieves the effect of protecting the pipeline heater.

The water volume detection mechanism can also be a buoyancy magnetic control switch. The buoyancy magnetic control switch includes a float, a float limiter and a reed switch. The reed switch and the pipeline heater are electrically connected in series, and the float is in the form of free floating It is installed in the tank through the floating ball limit; when working, the floating ball will be lowered as the water in the water tank decreases. If the floating ball is lowered to the set value of the water level in the water tank, the reed switch will be disconnected, and the power supply of the pipe heater will be cut off. , also achieve the role of protecting the heater.

The above various water quantity detection mechanisms all have a common feature: the weight of the water tank or the water level of the water tank is lowered to cause the water quantity detection mechanism to take mechanical action, cut off the power supply, and realize the function of protecting the pipeline heater.

The water volume detection mechanism can also be an electronic water volume monitoring switch, which is installed in the box body and electrically connected to the pipeline heater through an electric control device; when working, the water volume electronic monitoring switch

When the switch detects that the water level in the water tank is lower than the set value through the sensing terminal, the information is transmitted to the electric control device, and the electric control device cuts off the power supply of the heater, which also protects the heater.

The water tank is a water storage tank, and the bottom of the water storage tank is provided with a water outlet, and the pipe heater communicates with the water outlet.

The water tank can also be a balanced water tank, which can reduce the installation of electric pumps and ensure that water flows in the pipeline heater.

The level of the balance water tank is 2mm to 15mm lower than the water outlet of the pipeline heater, and the level of the balance water tank is 2mm to 15mm lower than the water outlet of the glass-coated electric heating tube, so that the water to be heated can Pour into the pipeline heater and be 2mm to 15mm lower than its water outlet. When heated to boiling water, the boiling water can cross the height space of 2mm to 15mm and flow out through the water outlet, avoiding the height of the space due to too low or Various defects caused by too high, such as: height space

When it is too low, hot water will flow out at only 80 degrees; when the height space is too high, it will be difficult to flow out hot water even at 100 degrees, resulting in a waste of energy.

The water quantity detection mechanism is also electrically connected with an alarm, and an alarm horn and/or indicator light are installed on the alarm, so that when the water quantity is lower than the set value, when the glass coating electric heating tube is cut off, an audible alarm signal is issued to prompt user.

There is also a steam recovery port near the water outlet of the pipeline heater, and the steam recovery port is used to guide the steam to the water inlet pipe or the outer periphery of the water tank. After the steam dissipates heat, the water temperature (warm water) in the water inlet pipe or the water tank rises, and then It is sent to the pipe heater to save electric energy; of course, a steam port directly connected to the atmosphere can also be set near the water outlet of the pipe heater to drain the steam.

If the pipe heater uses glass-coated electric heating tubes, the water inlet and outlet are connected with silicone parts. The function of the silicone parts has high heat resistance and flexibility. The silica gel part can be used as a shockproof part, and its sealing performance can be improved.

The glass-coated electric heating tube mentioned above has multiple independent lumens, and the upper and lower ends of each lumen are respectively used as water inlets and water outlets, and the corresponding water inlet pipes and water outlet pipes are connected and connected; in view of the glass-coated electric heating The outer wall of the tube is provided with a metal layer that is energized and heated, and the inner cavity of the glass tube is used for water flow through the pipeline. Therefore, each independent lumen in the glass tube can quickly transfer heat to the water in each independent lumen through the heating of the metal layer, so as to Realize the effect of instant boiling; the glass-coated electric heating tube has the following advantages: 1. There will be no scale in the tube, so it is especially suitable for making tea and drinking; 2. The glass-coated electric heating tube is light in weight and small in size, easy to carry and use; 3.
