Description

Technical Field

[0001] The utility model relates to the technical field of water heaters for heat generating devices, in particular to a small boiler heating chamber structure. Background Art

[0002] Steam boilers are commonly used in homes, restaurants, hotels and other scenarios, such as heating, steaming and baking. Existing electric heating boilers generally include a water inlet, water enters the heating cavity, the cavity is powered to heat the water, and finally vaporizes and sprays out from the water outlet. The water flow division in the existing boiler heating cavity is not obvious. It takes a while for the water to heat up, and then it is sprayed out to use water vapor when it reaches the vaporization temperature. When it is used at peak time, it takes time for the cavity to heat the water, and the water vapor supply is prone to intermittent interruption, making the supply unsustainable. On the other hand, the heating efficiency of the heating cavity of the existing electric heating pot is not high, the surface area in contact with water is small, the water vapor production efficiency is low, the water intake and water vapor output of the cavity cannot be carried out at the same time, and water vapor cannot be output continuously. Utility Model Content

[0003] In view of this, the purpose of the utility model is to provide a small boiler heating chamber structure, which has the characteristics of high heating efficiency and continuous output of water vapor.

[0004] The technical solution adopted by the utility model to solve its technical problems is:

[0005] A small boiler heating chamber structure comprises a main body shell, an upper cover installed on the main body shell, a water inlet is arranged on the upper cover, an outlet is arranged at the bottom of the main body shell, a heating chamber for heating water flow is arranged in the main body shell, a plurality of baffles are arranged in the heating chamber, a plurality of heating flow channels are formed between the baffles, water flows in from the water inlet, can flow through all the heating flow channels, and is output from the outlet.

[0006] A plurality of protrusions are arranged at the bottom of the heating flow channel.

[0007] The baffles include a plurality of first baffles in the form of straight plates and a plurality of second baffles in the form of annular plates. A straight first heating channel is formed between the first baffles, and an annular second heating channel is formed between the second baffles.

[0008] The main body shell is in a circular basin shape, and at least two first baffles are arranged in a semicircle on one side of the circular basin of the main body shell, and at least two second baffles are arranged in a semicircle on the other side of the circular basin of the main body shell.

[0009] The second baffle plate is semicircular and evenly distributed from the middle to the outside along the radial direction in the other semicircle of the main shell circular basin. The second heating channel is connected to the first heating channel, and water can flow from the outer circle of the disc to the center of the circular basin along the second heating channel.

[0010] The output port is arranged in the middle of the circular basin of the main body shell and is connected to the second heating flow channel. There are two output ports.

[0011] The water inlet is connected to the first heating flow channel.

[0012] A heating device is installed at the bottom of the main body shell, and a fixing clip for fixing the heating device is installed at the bottom of the main body shell.

[0013] The fixing clip is provided with a plurality of elastic abutting ears for abutting against the bottom surface of the heating device for fixing.

[0014] The heating device is an MCH heating sheet.

[0015] The beneficial effects of the utility model are:

[0016] 1. The heating chamber is provided with baffles and heating channels. Water flows in from the water inlet and flows through the heating channels in sequence. In the limited heating chamber space, the water flow path is increased as much as possible. After being heated by the heating channels, the water gradually heats up and finally heats up to vaporization and is output from the output port. The water in the heating chamber can flow in from the water inlet continuously, and the water vapor can be continuously output from the output port, which has wide applicability; the heating channel increases the heating area of ​​the water flow, the water flow heats up quickly, and the heating efficiency is improved.

[0017] 2. Several protrusions are arranged at the bottom of the heating flow channel, which can further increase the contact area between the water flow and the heating chamber, so that the water flow heats up faster and the heating efficiency is further improved.

[0018] 3. Water flows into the heating chamber from the water inlet, and first flows through the first heating channel for preliminary heating. After flowing through all the first heating channels, the water flows into the second heating channel. The second heating channel is designed to be annular. Compared with the straight first heating channel, the space distribution in the disc-shaped heating chamber is more reasonable, the volume utilization rate is higher, the path of the second heating channel is increased, and the annular second heating channel has a larger contact area with the water flow, which can fully heat the water body. At the same time, after the water flow is heated by the first heating channel, the water temperature entering the second heating channel increases, the water viscosity decreases, the friction of the water on the second heating channel decreases, and the fluidity increases. The longer second heating channel can fully heat the water flow and improve the heating efficiency. At the same time, the first heating channel is designed to be straight because the water flow has just entered from the water inlet, the water temperature is low, and the fluidity is relatively low. The straight water channel can facilitate the flow of water. After preliminary heating, it enters the annular second heating channel. The design of the straight first heating channel and the annular second heating channel can well coordinate the changes in water flow rate at different temperatures, so that the input and output of water flow are more balanced and stable, and the output of water vapor is more stable and linear.

[0019] 4. The heating device is installed at the bottom of the main body shell by means of a fixed clip. The heating device is an efficient and environmentally friendly MCH heating sheet. The upper part of the fixed clip adopts an elastic abutment ear to fix the MCH heating sheet, so that the MCH heating sheet is fully in contact with the bottom of the main body shell. At the same time, the contact between the MCH heating sheet and other parts is reduced as much as possible, so that the heat generated by the MCH heating sheet is absorbed by the main body shell to the maximum extent, further improving the heating efficiency.

In the limited space of the heating chamber 10, the flow path of the water flow is increased as much as possible. After being heated by the heating channel 102, the water flow gradually heats up and is finally heated to vaporization and output from the output port 11. The water flow in the heating chamber 10 can flow in continuously from the water inlet 20, and the water vapor can be continuously output from the output port 11, which has wide applicability; the heating channel 102 increases the heating area of ​​the water flow, the water flow heats up quickly, and the heating efficiency is improved.

[0030] Reference Figure 3 , a plurality of protrusions 12 are provided at the bottom of the heating channel 102. Further, a plurality of protrusions 12 are provided at the bottom of the heating channel 102, which can further increase the contact area between the water flow and the heating chamber, so that the water flow heats up faster and the heating efficiency is further improved.

[0031] Reference Figure 3 , Figure 4 The baffle plates 101 include a plurality of first baffle plates 1010 in the form of straight plates and a plurality of second baffle plates 1011 in the form of annular plates.
