Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] In a first aspect, this embodiment provides a heater. Figure 1 This is a schematic diagram of the structure of a heater provided in this embodiment. Figure 2 A diagram showing the usage status of a heater provided in this embodiment.

[0028] like Figure 1 and Figure 2 As shown, the heater 1 of this embodiment includes a water inlet 2 and a water outlet 4. When the heater 1 is in use, the water inlet 2 is higher than the water outlet 4.

[0029] For some examples, see Figure 1 and Figure 2The heater 1 includes a shell, a water inlet 2 and a water outlet 4 are arranged on the shell, and a plurality of electric heating tubes are arranged inside the shell. After the heated medium enters the shell of the heater from the water inlet 2, it fully contacts and exchanges heat with the plurality of electric heating tubes during the process of flowing toward the water outlet 4 to achieve temperature rise. The heater 1 of this embodiment uses a plurality of electric heating tubes for heating, which is conducive to further reducing the external size of the heat exchanger 1.

[0030] For example, see Figure 1 , the electric heating tube uses aluminum die-cast electric heating tube. The aluminum die-cast electric heating tube has better structural strength and corrosion resistance, and has good thermal conductivity. In addition, the aluminum die-cast electric heating tube is lighter in weight, which is conducive to reducing the overall weight of the heater.

[0031] For example, see Figure 1 A guide plate may also be provided in the shell of the heater 1 to further slow down the flow rate of the medium to be heated and extend the flow path of the medium to be heated, thereby improving the heat exchange efficiency between the medium to be heated and the electric heating tube.

[0032] For some examples, see Figure 1 and Figure 2 The heater 1 is box-shaped, including a bottom surface, a top surface and side surfaces. The bottom surface and the top surface are parallel to each other, and the side surfaces are connected between the top surface and the bottom surface to form a box shape. This arrangement makes the appearance of the heater 1 more regular and convenient for installation and arrangement. However, it should be noted that in other embodiments, the heater 1 may also adopt other regular shapes, or may also adopt irregular shapes. The specific shape can be designed according to the installation space and usage requirements, and this embodiment does not impose too many restrictions on this.

[0033] The heater 1 provided in this embodiment includes a water inlet 2 and a water outlet 4. When the heater 1 is in use, the water inlet 2 is higher than the water outlet 4. Since the water inlet 1 is higher than the water outlet 4, the medium to be heated can flow toward the water outlet 4 autonomously under the action of its own gravity after entering the heater 1 from the water inlet 2, without the need for external force to drive; and, during the autonomous flow of the medium to be heated, it can fully contact with the heating components in the heater 1 to ensure the heat exchange effect, which is conducive to improving the heating efficiency. Therefore, the heater 1 provided by the utility model can reduce the external dimensions while achieving better heating efficiency, which is conducive to the miniaturization design of the equipment.

[0034] In some embodiments, Figure 1 and Figure 2 As shown, a water inlet joint 3 is provided on the water inlet 2. A water outlet joint 5 is provided on the water outlet 4. The water flow direction in the water inlet joint 3 is parallel to the water flow direction in the water outlet joint 5.

[0035] For some examples, see Figure 1 and Figure 2The water inlet connector 3 and the water outlet connector 5 can be any one of an external threaded terminal connector, a ferrule connector, and a self-fixing connector, and this embodiment does not impose too many restrictions on this.

[0036] It should be noted that the water inlet connector 3 and the water outlet connector 5 may be the same or different.

[0037] The water flow direction in the water inlet joint 3 of this embodiment is parallel to the water flow direction in the water outlet joint 5 , which is beneficial to make the water flow inside the heater 1 smoother and more stable, thereby helping to improve the heating efficiency of the heater 1 .

[0038] In some embodiments, Figure 1 and Figure 2 As shown, the water inlet 2 and the water outlet 4 are located on the same side of the heater 1 .

[0039] For some examples, see Figure 1 and Figure 2 A guide plate is provided inside the heater 1, and the guide plate is located between the water inlet 2 and the water outlet 4. After the cold water enters the heat exchanger 1 from the water inlet 2, it can flow to the side away from the water inlet 2 under the action of the guide plate, and bypass the guide plate on the side away from the water inlet 2 and flow back to the direction of the water outlet 4. This arrangement extends the flow path of the cold water and further ensures that the cold water can be fully heated.

[0040] In some examples, such as Figure 1 and Figure 2 As shown, the water inlet 2 and the water outlet 4 can be located at the front side, rear side, left side or right side of the heater 1. This embodiment does not impose too many restrictions on this. Preferably, as Figure 1 and Figure 2 As shown, the water inlet 2 and the water outlet 4 are located at the front side of the heater 1. This arrangement facilitates the layout of the inlet and outlet water pipes.

[0041] The water inlet 2 and the water outlet 4 of this embodiment are located on the same side of the heater 1 , which reduces the difficulty of arranging the water inlet pipeline and the water outlet pipeline and facilitates the overall installation and layout of the heater 1 .

[0042] In some embodiments, Figure 1 and Figure 2 As shown, the water inlet 2 and the water outlet 4 are arranged alternately.

[0043] It is understandable that the staggered arrangement of the water inlet 2 and the water outlet 4 means that when the heater 1 is in use, the water inlet 2 and the water outlet 4 do not correspond to each other in the vertical direction, that is, the water inlet 2 and the water outlet 4 are close to the left and right sides of the heater 1 respectively.

[0044] In some examples, such as Figure 1 and Figure 2As shown, the water inlet 2 is close to the right side of the heater 1, and the water outlet 4 is close to the left side of the heater 1. There is a certain distance between the two. This arrangement can fully heat the cold water entering the heater 1 through the water inlet 2.

[0045] It is understandable that, in other embodiments, the water inlet 2 may be arranged at a left position close to the heater, and the water outlet 4 may be arranged at a right position close to the heater 1 .

[0046] In this embodiment, the water inlet 2 and the water outlet 4 are arranged alternately and the water inlet 2 is higher than the water outlet 4, which can extend the flow path of the medium to be heated, thereby improving the heat exchange efficiency between the medium to be heated and the electric heating tube.

[0047] In some embodiments, Figure 1 and Figure 2 As shown, the water inlet 2 is close to the top surface of the heater 1 , and the water outlet 4 is close to the bottom surface of the heater 1 .

[0048] The water inlet 2 of this embodiment is close to the top surface of the heater 1, and the water outlet 4 is close to the bottom surface of the heater 1, so that the water inlet 2 and the water outlet 4 have a large height difference in the vertical direction, which can make the medium to be heated flow toward the water outlet 4 autonomously under the action of its own gravity, and is conducive to extending the flow path of the medium to be heated, and further improving the heat exchange efficiency between the medium to be heated and the electric heating tube.

[0049] In some embodiments, Figure 1 As shown, the heater 1 further includes: a thermostat 6 connected to the heater 1. The thermostat 6 is used to control the heating temperature of the heater 1.

[0050] For some examples, see Figure 1 The temperature controller 6 can be a sudden jump type temperature controller, a liquid expansion type temperature controller, a pressure type temperature controller, an electronic type temperature controller, a digital temperature controller, etc. This embodiment does not make too many restrictions on this.

[0051] For some examples, see Figure 1 The temperature controller 6 also includes a temperature probe or a thermocouple. The temperature controller 6 converts the electrical signal fed back by the temperature probe or the thermocouple into a temperature value, and controls the heater 1 to be turned on and off according to the set temperature value to achieve the purpose of controlling the temperature range.

[0052] In this embodiment, the temperature controller 6 is set, and the temperature of the temperature controller 6 can be restored, so that the heater 1 can be protected. When the temperature of the heater 1 reaches the upper limit temperature of the thermostat 6, the thermostat 6 can disconnect the power supply of the heater 1, so that the heater 1 no longer heats up. That is, it can prevent the heater 1 from being damaged due to overheating, and can also play a role in energy saving. When the temperature of the heater 1 is lower than the lower limit temperature of the thermostat, the thermostat 6 can connect the power supply of the heater 1 to prevent the water temperature of the heater 1 from being too low.

[0053] In some embodiments, Figure 1 As shown, the heater 1 further includes a fuse 7. The fuse 7 is connected in series with the heater 1. The fuse 7 is used to prevent the heater 1 from overheating.

[0054] For some examples, see Figure 1 The fuse 7 can be a flat-head tubular fuse, a pointed-head tubular fuse, a guillotine fuse, a spiral fuse, a plug-in fuse, a flat-plate fuse, a wrap-type fuse, a patch fuse, etc. This embodiment does not impose too many restrictions on this.

[0055] The heater 1 of this embodiment further includes a fuse 7, which can form a second line of protection for the heater 1. If the thermostat 6 fails, the heating temperature of the heater 1 will continue to rise, and when the heating temperature of the heater 1 reaches the melting temperature of the fuse 7, the fuse 7 will automatically disconnect, cutting off the heating power supply of the heater 1, protecting the heater 1 and preventing the safety risk caused by overheating of the heater 1.

[0056] In some embodiments, see Figure 1 and Figure 2 , heater 1 is a resistance wire heater.

[0057] For some examples, see Figure 1 and Figure 2 The heater 1 is provided with an electric heating tube inside, and the resistance wire is arranged in the electric heating tube of the heater 1. In addition, in order to prevent the electric heating tube from conducting electricity, an insulating layer is provided between the resistance wire and the tube wall of the electric heating tube. With such arrangement, the resistance wire can generate heat after being energized, and the heat energy is transferred to the tube wall of the electric heating tube to heat the water in the heater 1.

[0058] For example, the inner wall surface of the electric heating tube is plated with an insulating layer and / or the resistance wire is wrapped with an insulating layer.

[0059] For some examples, see Figure 1 and Figure 2 The heater 1 is provided with a water channel inside, and the water channel is connected between the water inlet 2 and the water outlet 4. The resistance wire is arranged on the water channel along the extending direction of the water channel. In this way, the heat generated by the resistance wire after being energized can heat the water in the water channel along the way. It can be understood that in order to ensure the heating efficiency, the water channel is arranged in a circuitous way in the heater.

[0060] The heater 1 of this embodiment adopts a resistance wire heater, which is conducive to accurate control of the heating temperature, and has a uniform heating effect, high thermal efficiency and a wide range of applications.

[0061] In a second aspect, this embodiment provides a water heater, referring to Figure 1 The water heater includes the heater 1 in the above embodiment.

[0062] In some examples, the water heater also includes an inner tank, a preheater, a temperature control valve and a thermostatic valve. The preheater is used to heat the water in the inner tank to a higher temperature. The temperature control valve is used to take out an appropriate amount of high-temperature water from the inner tank according to the use temperature set by the user, and mix it with cold water and send it to the heater 1. After being instantly heated by the heater 1, it flows to the thermostatic valve. The thermostatic valve mixes the hot water output by the heater 1 with the cold water to the set temperature and outputs it from the user end to achieve a constant temperature effect.

[0063] For some examples, see Figure 1 The water heater may include a plurality of heaters 1. The heating temperature of each heater 1 is different. In this way, the water heater can instantly switch water of different temperatures according to the user's choice.

[0064] The water heater provided in this embodiment includes the above-mentioned heater 1, so it can have a smaller volume while ensuring the heating efficiency, reducing the demand for installation space, and can be suitable for more application scenarios.

[0065] In a third aspect, this embodiment provides a base station. Figure 3 A schematic diagram of the structure of a base station provided in this embodiment.

[0066] See also Figures 1 to 3 The base station includes: a cleaning water tank and the heater 1 in the above embodiment. The cleaning water tank is used to contain cleaning water. The water inlet 2 of the heater 1 is in fluid communication with the cleaning water tank. The heater 1 is used to instantly heat the cleaning water output from the cleaning water tank and output it through the water outlet 4.

[0067] For some examples, see Figures 1 to 3 The water outlet of the cleaning water tank is connected to the water inlet of the heater, and the water outlet of the heater is connected to the cleaning chamber of the sweeper at the base station. The cleaning water output from the cleaning water tank is immediately heated by the heater and then sent to the cleaning chamber of the sweeper at the base station to clean the mop of the sweeper. Using hot water to clean the mop of the sweeper can improve the cleaning efficiency and cleaning effect of the mop.

[0068] For some examples, see Figures 1 to 3The base station also includes a damping sensor. When the damping sensor senses that the resistance of the mop of the sweeper exceeds the preset value, it means that the mop is stuck with garbage that is difficult to clean. The damping sensor transmits a signal to the controller. After receiving the signal, the controller controls the heater 1 to start and heat the cleaning water. After the mop is cleaned with hot cleaning water, the damping of the mop's rotation is reduced. Then the controller can control the heater 1 to turn off and rinse the mop with normal temperature water until the mop is completely clean.

[0069] For some examples, see Figures 1 to 3 The water outlet of the heater 1 may also be provided with a dosing device for mixing a cleaning agent into the cleaning water, thereby further improving the cleaning effect of the mop of the sweeper.

[0070] The base station provided in this embodiment includes the above-mentioned heater 1, which is used to heat the cleaning water output from the cleaning water tank in the base station, which is beneficial to improve the cleaning efficiency of the sweeper. At the same time, since the base station of this embodiment adopts the above-mentioned heater 1, it has a smaller volume, reduces the floor space, and can be placed in a smaller space.

[0071] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0072] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention. The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present invention, and these improvements and variations should also be regarded as the protection scope of the present invention.
