Problems solved by technology

Due to the large thermal inertia of aluminum, there will be the following problems: 1. When starting up, it takes a long time for 15 to 30 seconds (seconds) to warm up before the cast aluminum can be heated to the required temperature; In the case of water, the heat generated by the heating resistance wire cannot keep up with the heat absorbed by the liquid in time, which will cause the temperature of the cast aluminum to drop. If the required water temperature cannot drop, you need to continue to wait for heating; 3. If the heater is in standby, you need to Use the control to keep the temperature of the cast aluminum constant, resulting in a waste of energy; 4. The cast aluminum heater with such a high thermal inertia must be preheated to obtain water at a constant temperature. When the water is continuously discharged, the water temperature cannot be kept constant.
Because of the inertia of high heat, it is impossible to realize the continuous change and adjustment of water temperature
At the same time, the production process of cast aluminum is complex, large in size and heavy in weight.
[0004] Based on the above problems, there are some solutions to improve, such as making a plastic liquid flow channel in a stainless steel thick film round tube to avoid the influence of thermal inertia. Plastic has a certain hardness and needs to be inserted into the stainless steel outer tube, which can be easily inserted In the stainless steel round tube, the size fit needs to reduce the outer diameter of the plastic liquid flow channel, which cannot achieve a tight fit
There is no problem with the installation, but it will cause sealing problems, so that the water cannot flow completely in accordance with the flow direction of the liquid channel. There will always be a part of the water that will take a shortcut from the gap that is not tightly sealed. The water flow channel is certain, which will inevitably lead to part of the water not flowing , become stagnant water, and continue to heat there, eventually leading to gasification, resulting in steam ejection, and intermittent water discharge. At the same time, because the seal between the plastic box and the metal can only be sealed by the sealing ring, it cannot meet the requirement of a storage pressure of 8 to 10 bar. In the middle of the pressure, it may also be aging due to the speed or the sealing ring being used in a high temperature environment for a long time, and there is a risk of leakage

Abstract

The invention relates to a liquid heating device which comprises a main body and a heating element which are each of a cylindrical structure. The surface of the main body is sleeved with the heating element, the heating element is composed of an outer pipe and a heating circuit printed on the outer surface of the outer pipe, the main body is composed of an inner pipe and a silicone wire, the two ends of the inner pipe are matched with the two ends of the outer pipe in a sealed mode respectively, an inner cavity is formed between the outer pipe and the inner pipe, a spiral positioning groove is formed in the periphery of the inner pipe, and the silicone wire is spirally wound at the periphery of the inner pipe and matched with the spiral positioning groove in a positioning mode; the silicone wire is tightly pressed in the inner cavity formed between the outer pipe and the inner pipe, the silicone wire, the inner pipe and the inner wall of the outer pipe jointly form a spiral liquid flowing path in an enclosing mode, and a liquid outlet channel and a liquid inlet channel are arranged on the portions, corresponding to the upper end and the lower end of the liquid flowing path, of the main body. The liquid heating device has the advantages of being simple and reasonable in structure, high in heating response speed, low in energy consumption and the like.

Description

technical field [0001] The present invention relates to a liquid heating device, in particular to a liquid heating device primarily for heating water to a temperature below the vapor state. Background technique [0002] Generally, in heating appliances that require continuous hot water, the heating resistance wire is wrapped or filled with an insulating layer and embedded in cast aluminum with good thermal conductivity. At the same time, the stainless steel tube is bent to form a continuous liquid flow channel. in cast aluminum. [0003] Because the heat generated by the heating resistor cannot directly exchange heat with water, the cast aluminum needs to be heated to a certain temperature first, and the heat on the cast aluminum passes through the stainless steel tube liquid channel to generate heat exchange with water. Due to the large thermal inertia of aluminum, there will be the following problems: 1. When starting up, it takes a long time for 15 to 30 seconds (seconds...
