[0021] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.
[0022] Reference Figure 1 As shown, a new type of anti-freeze and anti-dry burning intelligent toilet heater with counterflow mixed heating includes a heating box 1, a heating tube, a temperature measurement module, and a thermostat 6.
[0023] Reference Figure 1 , Figure 2 As shown, the interior of the heating box body 1 has a chamber, and the chamber has a diverter partition 11, so that the diverter partition 11 divides the chamber into a heating chamber 2 and a mixing chamber 3 from bottom to top. A flange is fixedly provided on the top of the heating box body 1, so that the heating chamber 2 and the mixing chamber 3 form a closed space. In this embodiment, the heating tube adopts a U-shaped heating tube. The heating tube is an existing structure and will not be repeated here. The heating tube is arranged in the heating chamber 2, and the two connecting ends of the heating tube are respectively fixed on the flange, and the heating tube is electrically connected to the power module, so that the power module provides power to the heating tube.
[0024] A water inlet 21 which is connected to the heating chamber 2 is provided at the lower part of the heating box body 1. The water inlet is connected to a water inlet pipe, so that water flows into the heating chamber 2 through the water inlet 21, so that the heating pipe heats the water in the heating chamber 2. A diversion guide port 111 is provided on the top of the diversion baffle 11, so that the heating chamber 2 is connected to the mixing chamber 3, so that the heated water in the heating chamber 2 flows upward through the diversion guide port 111 into the mixing chamber 3. There is water storage in the mixing chamber 3, so that the hot water flowing back in the heating chamber 2 is fully mixed with the water in the mixing chamber 3, so that the water storage in the mixing chamber 3 reaches the corresponding set temperature. A water outlet 31 which is connected to the mixing chamber 3 is provided at the upper part of the heating box body 1, so that the water storage in the mixing chamber 3 can be discharged through the water outlet 31.
[0025] More preferably, a protrusion is vertically arranged in the middle of the inner wall of the mixing chamber 3, thereby shortening the distance between the inner wall of the mixing chamber 3 and the diversion guide port 111, so that the hot water flowing into the mixing chamber 3 flows to both sides under the action of the protrusion, so that the hot water in the heating chamber 2 can be better mixed with the water in the mixing chamber 3, and the inner wall space of the mixing chamber 3 is divided into two spaces under the action of the protrusion, thereby increasing the water storage ratio inside the mixing chamber 3.
[0026] Reference Figure 2 , Figure 3 As shown, the width of the heating chamber 2 is greater than the width of the mixing chamber 3, so that the space of the mixing chamber 3 is smaller than the space of the heating chamber 2, so that the effective volume of ice in the heating box 1 is reduced, and the ratio of the air surplus in the mixing chamber 3 to the overall water storage reaches 14.96%, so that the heating box 1 has good antifreeze ability and can withstand the low temperature of minus 35 degrees Celsius under normal use, so as to avoid the freezing and cracking of stored water in areas with sub-zero temperatures.
[0027] Reference Figure 1 As shown, the temperature measuring module includes a first temperature detection probe 4 and a second temperature detection probe 5. A first detection mounting hole 12 is provided at the water inlet of the lower part of the heating chamber 2. The first temperature detection probe is fixedly arranged on the first detection mounting hole 12. A second detection mounting hole 13 is provided on the top wall of the mixing chamber 3. The second temperature detection probe 5 is fixedly arranged on the second detection mounting hole 3. Specifically, the second temperature detection probe 5 is arranged on a convex column. The present embodiment also includes a control system. The first temperature detection probe 4 and the second temperature detection probe 5 are electrically connected to the control system respectively. In the present embodiment, the first temperature detection probe 4 and the second temperature detection probe 5 are preferably temperature detectors. The first temperature detection probe 4 is used to detect the heating The first temperature detection probe 4 and the second temperature detection probe 5 detect the inlet water temperature in the heating chamber 2, and the second temperature detection probe 5 is used to detect the water temperature entering the mixing chamber 3, and feed back the temperature information to the control system respectively, so that the water temperature in the heating box can be monitored in real time. When the first temperature detection probe 4 and the second temperature detection probe 5 detect that the temperature difference between the heating chamber 2 and the mixing chamber 3 is lower than the set temperature, the control system increases the supply of the heating tube to increase the water temperature in the heating chamber 2; or when the first temperature detection probe 4 and the second temperature detection probe 5 detect that the temperature between the heating chamber 2 and the mixing chamber 3 reaches the set temperature, the control system reduces the power of the heating tube to reduce the water temperature in the heating chamber 2, so that the water temperature in the mixing chamber is maintained at the set temperature.
[0028] Reference Figure 1 As shown, a third detection mounting hole 14 is provided at the lower portion of the heating chamber 2, and the thermostat is fixedly mounted on the third detection mounting hole 14. The thermostat 6 is electrically connected to the heating tube. In this embodiment, the thermostat 6 preferably adopts a high-sensitivity thermostat. The thermostat 6 is used to limit the water temperature in the heating chamber 2. When the thermostat 6 detects that the water temperature in the heating chamber 2 is higher than the limit value, the thermostat 6 automatically disconnects and controls the heating tube to stop heating.
[0029] In this embodiment, the distance between the thermostat 6 and the heating tube is 2mm-4mm, and 3mm is preferably used in this embodiment so that the thermostat can limit the temperature rise within the fastest time to ensure that the thermostat 6 can disconnect the power supply as quickly as possible when the temperature is too high to play a protective role and prevent high-temperature dry burning.
[0030] The water inlet 21 is arranged on the side wall of the heating chamber 2, and the distance between the water inlet 21 and the bottom of the heating chamber 2 is 3-4mm, and preferably 3.5mm in this embodiment, so that 3.5mm of water will be reserved at the bottom of the heating chamber 2 after each use of the heating box 1, so that water can be maintained when the water is cut off, to prevent the water supply network from being backflowed and causing the heating box to dry out due to lack of water when the water is cut off. At the moment the heating box is started, the heating tube makes the water in the heating chamber 2 generate water vapor and quickly triggers the thermostat to disconnect the power supply of the heating tube, thereby playing a protective role and avoiding dry burning of the heating box.
[0031] Reference Figure 5 As shown, two strip-shaped mounting holes 15 are provided on one side of the heating box body 1, so that different mounting positions can be adjusted to the greatest extent, solving the problem of inconsistent mounting holes and difficulty in universal use.
[0032] Of course, the above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with this technology to understand the content of the utility model and implement it accordingly. They cannot be used to limit the protection scope of the utility model. Any modifications made according to the spirit of the main technical scheme of the utility model should be included in the protection scope of the utility model.
