Drinking water heating device with separation water tank

Abstract

The invention discloses a drinking water heating device with a separation water tank. The drinking water heating device comprises a seat body and a separation water tank of the seat body, wherein a water outlet nozzle, an instant heating pipeline heater, a balance water tank and a water pump are arranged on the seat body, a water inlet and a backflow opening are arranged on the balance water tank, and the water inlet is connected with the water pump. The drinking water heating device is characterized in that a pumping opening of the water pump is communicated with a pumping pipeline, and the other end of the pumping pipeline is inserted into the separation water tank through the upper part of the separation water tank. The drinking water heating device has the advantages that the defect that the adoption of a check valve is needed in the prior art because the pumping pipeline is inserted into the separation water tank from the bottom is overcome through inserting the water pumping pipeline from the upper part of the separation water tank, the adoption of the check valve is avoided, the cost is reduced, the defect of water leakage when the separation water tank is taken out for water addition can also be avoided, in addition, the whole structure is simple, and the use is convenient.

Description

technical field [0001] The invention relates to the technical field of drinking water heating devices, in particular to a drinking water heating device with a separate water tank; Products such as tea machines and industrial water boilers (suitable for people to drink). Background technique [0002] Existing heating devices for drinking water, such as: electric water boilers, electric kettles, etc., will be provided with inner tanks, that is, water storage tanks; and existing electric water boilers, the water storage tanks have two types: separate type and one-piece type, namely : The water storage tank and the water boiler (housing) are detachable or conjoined structures; in view of the detachable water storage tank, it is convenient for people to take out and fill tap water, especially the most widely used on the electric kettle. [0003] However, the above-mentioned traditional electric water boiler still has the following deficiencies: (1) the above-mentioned electric w...

Problems solved by technology

[0003] However, the above-mentioned traditional electric water boiler still has the following deficiencies: (1) the above-mentioned electric water boiler, such as an electric kettle, has a separate water storage tank and a seat body, and an electric heating device (that is, a charging device) is installed at the bottom of the water storage tank. part), the base is connected with a power cord, the water storage tank sits on the base, and it is electrically connected with the base by means of coupling. However, in view of the electric heating device connected to the bottom of the water storage tank, when the water storage tank is taken out and filled It is easy to wet the water storage tank, or even wet the electrical parts, causing electric leakage. Therefore, there is a certain potential safety hazard; (2) The base and the bottom of the water storage tank are electrically connected by coupling, which is easy to be caused by the metal insertion between the couplers. (3) The electric heating method of the electric water boiler mostly uses heating devices such as electric heating tubes and electric heating plates to directly heat the (inner tank) storage The water in the water tank is heated, but it is still impossible to realize instant heating for people to drink at any time; moreover, the inner tank is equipped with boiled water, if it cannot be drunk in time, after the temperature drops, it will affect the drinking of boiled water. For example, it cannot be used to make tea for drinking; (4) If the water stored in the water storage tank is not drinkable, the water will be wasted and power consumption will be lost

[0005] Yet above-mentioned electric water boiler with separated water storage tank, the structure with check valve at the bottom of its water tank still has the following deficiencies: (1) the bottom of the separated water tank with check valve, its structure seems complicated all the time, and the use of check valve A return valve will increase the cost; (2) Install a check valve at the bottom of the separation water tank, its sealing performance is always poor, and it is easy to cause water leakage during use; (3) Install a check valve at the bottom of the separation water tank, in view of the fact that the separation water tank needs to be taken out frequently Therefore, the frequent plugging and unplugging of the check valve will definitely be easily damaged, causing water leakage, and even making the separated water tank scrapped; insufficient
