Description

Technical Field

[0001] The utility model relates to the technical field of water boilers, in particular to a variable-mode heating water tank for a water boiler. Background Art

[0002] A step-by-step coupled instantaneous water heater is an energy-saving device that heats water layer by layer by feeding water from the bottom until the water boils. Furthermore, while the water heater is in use, the water inlet is open, improving the separation of hot and cold water while ensuring a single boil. This healthy water heater alleviates the occurrence of "yin and yang water" (yin and yang water) and uses electrical energy control to ensure a single boil, completely avoiding repeated heating. After heating and boiling one liter of water, another liter of water is added from the bottom and heated until the tank is full. This step-by-step coupled instantaneous water heater can continuously deliver boiling water, eliminating the waiting time required by traditional water heaters to boil the entire tank before dispensing water.

[0003] In the prior art, although commercial water heaters can be switched between step mode and instant heating mode, due to the large volume of the water tank of the commercial water heater, the water inlet in the water tank needs to be in a water-intake state during the heating process. At this time, the newly added water is mixed with the original water in the water tank, which will continuously lower the water temperature in the water tank. To heat the water tank from the initial temperature to the preset temperature, the water tank needs to be heated continuously, that is, the heating element is always in the on state. In addition, the heating time will be very long for heating the entire water tank, which reduces the heating efficiency. Utility Model Content

[0023] The present invention will be further described below with reference to the embodiments, but is not limited to the contents of the specification.

[0024] The variable mode heating water tank of a water boiler provided by the present invention can be used in household mode as well as in commercial mode. Generally speaking, the main difference between household mode and commercial mode lies in the size. The corresponding heating water tank size is selected according to different application modes. Since the heating element 5 in the heating box body 1 of the present invention is arranged close to the bottom of the box body 1, and the box body 1 is divided into smaller spaces of different sizes that can be interconnected at the lower part through the partition component 3, the heating element 5 can independently heat the smaller space at the lower part during the heating process, thereby improving the heating efficiency.

[0025] like Figure 1 As shown, the heating water tank includes a box body 1 and a heating element 5 near the bottom of the box body 1. The bottom of the box body 1 has a water inlet 11 and multiple water outlets on the wall of the box body 1. After assembly, the number of water outlets is three, and the water outlets include a second water outlet 13 and two first water outlets 12. The water inlet 11 is installed at the bottom of the box body 1, and the two first water outlets 12 are arranged at the same height on the inner wall of the box body 1 and are opposite to the position of the driving member 2. The second water outlet 13 is arranged on the left side wall of the box body 1, and the height of the second water outlet 13 is lower than the height of the partition component 3. This ensures that the first water outlet 12 and the second water outlet 13 will not interfere with each other during the water discharge process, and the water in the first space 14 can be discharged without passing through the water in the second space 15, thereby ensuring that the water in the second space 15 is maintained at the set water volume.

[0026] In addition, in order to prevent the box body 1 from colliding with external hard objects during use, a protective shell can be provided on the outer periphery of the box body 1, and through holes are provided in the protective shell corresponding to the water inlet 11 and the water outlet. This can not only protect the box body 1, but also ensure the normal use of the heating water tank.

[0027] When the cam 31 is in the closed position, the cam 31 is in the closed position, and the cam 31 is in the closed position, so that the cam 31 is in the open position and the cam 31 is in the closed position.

[0028] In this embodiment, the water tank is mostly a square box body 1, which is placed above a horizontal bracket. The box body 1 has a certain height. The horizontal cross-section of the box body 1 can be square or rectangular, and the height of the box body 1 is greater than the long side of the rectangle. The following is a detailed introduction taking the cross-sectional shape of the box body 1 as a rectangle and the height of the box body 1 as greater than the length of the box body 1 as an example.

[0029] like Figure 2 and Figure 3 As shown, after the installation is completed, the water inlet 11 is located at the bottom of the box body 1, and an electromagnetic water inlet valve is installed on the water inlet 11. At the same time, in order to make the heating water tank easy to operate, an integrated chip is provided in the electric heating water tank. The integrated chip is preset with a program for opening and closing the water inlet 11, the water outlet, and the heating element 5. The program can control when the water inlet 11, the water outlet, and the heating element 5 are opened or closed, and can also control the length of time of opening. At this time, an electromagnetic water inlet valve is installed at the water inlet 11, and a solenoid valve is also installed at the water outlet. There is a water outlet valve, and the water inlet valve, water outlet valve, heating element 5 and driving element 2 are all electrically connected to the integrated chip. At this time, the electric heating water tank can automatically fill with water, automatically discharge water and automatically heat according to the preset program, or the water inlet, water outlet and heating programs of the heating water tank can be manually controlled. Correspondingly, buttons corresponding to different functions can be installed on the side of the electric heating water tank, and a display screen is also provided on the side wall of the box body 1 to display the specific temperature value in the box body 1. Different buttons are pressed according to the user's actual water use needs to make the water boiler operate normally.

[0030] Specifically, since the partition component 3 is arranged close to the bottom of the box body 1, for example, the distance between the partition component 3 and the bottom of the box body 1 is about 1 / 6-1 / 7 of the height of the box body 1, that is, the water volume in the second space 15 is much smaller than the water volume in the first space 14. When the water volume in the box body 1 reaches the set lower limit, the driving member 2 is started and the movable plate 31 is driven to move, so that the first through hole 311 and the second through hole 331 are misaligned. In this way, when the electric heating member 5 is started, only 1 / 6 or 1 / 7 of the volume of the second space 15 of the box body 1 is heated, shortening the heating time. The heating time ensures that the water temperature in the box 1 reaches the design value as soon as possible, and when the water level in the second space 15 reaches the upper limit, the movable plate 31 is driven to move so that the first through hole 311 on the movable plate 31 is connected with the second through hole 331, that is, the water at the bottom of the box 1 can gradually rise to and fill the first space 14 through the water flow channel. At this time, the first space 14 and the second space 15 are connected in a stepping mode, which is equivalent to raising the initial temperature of the water in the box 1 and ensuring that the water in the box 1 is always higher than the room temperature.

[0031] In order to measure the water temperature of the box body 1 in time and meet the set requirements, a temperature sensor 6 is set in the box body 1. Specifically, there are two temperature sensors 6, which are recorded as the first temperature sensor 61 and the second temperature sensor 62, which are respectively installed in the first space 14 and the second space 15 in the box. In actual use, the first temperature sensor 61 and the second temperature sensor 62 are both electrically connected to the integrated chip. The first temperature sensor 61 is set on the inner wall of the first space 14, and the height of the first temperature sensor 61 is level with the height of the first water outlet 12, that is, at this time, the first temperature sensor 61 senses the temperature of the entire box body 1, and the second temperature sensor 62 is set at the bottom of the second space 15, that is, the second temperature sensor 62 senses the temperature of the water in the second space 15.

[0032] like Figure 4 and Figure 5 As shown, a pair of ribs 34 are protruding from the inner wall of the box body 1, and the paired ribs 34 are arranged up and down along the height direction of the box body 1 in the box body 1, respectively located above and below the movable plate 31, and at least one rib 34 is slidably connected to the edge of the movable plate 31, and the two ends of the rib 34 are respectively fixed to the inner wall of the box body 1, and the rib 34 is protruding toward the inside of the box body 1, and the side wall where the rib 34 is located is not in the same plane as the driving end 22, forming a limiting structure for limiting the up and down movement of the movable plate 31.

[0033] The limiting structure can be a structure in which ribs and grooves cooperate with each other, or the limiting structure can also be a structure in which holes and columns cooperate with each other, and one side of the hole is fixed to the inner wall of the box body 1, and a notch is provided on the side wall opposite to the fixed side, and the column and the edge of the movable plate 31 are connected by a connecting piece, so that it can be ensured that the connecting piece can pass through the notch to make the column and the hole slide together; in addition, the limiting structure protrudes from the side of the box body 1, and the edge of the movable plate 31 is inserted into the gap between the paired ribs, that is, the limiting structure can support the movable plate 31; when the movable plate 31 slides on the limiting structure, the limiting structure and the movable plate 31 also form a slideway for the movable plate 31 to slide, and the limiting structure can limit the movable plate 31 to be installed in the height range of the limiting structure. At this time, the limiting structure forms a certain guiding effect on the movable plate 31, so that the movable plate 31 can be quickly installed on the inner side of the box body 1, and can prevent the movable plate 31 from falling off from the paired ribs 34 during the sliding process, thereby ensuring that the movable plate 31 can slide stably.

[0034] In this embodiment, Figure 2 and Figure 3The cam 34 is fixed to the left and right sides of the cam 34, so that the cam 34 can be fixed to the left and right sides of the cam 34. Figure 3 As shown, the driving member 2 can generate a sliding force along the thickness direction of the box body 1. In order to prevent the convex ribs 34 from restricting the movement of the driving member 2, the extension direction of the paired convex ribs 34 is arranged parallel to the direction of the driving force generated by the driving member 2, that is, the convex ribs 34 extend along the thickness of the box body 1. In this way, the movable plate 31 can only slide in the extension direction of the convex ribs 34, and can also avoid the movable plate 31 from moving up and down along the height, further ensuring the sliding stability of the movable plate 31.

[0035] In order to ensure that the driving member 2 is an electromagnetic driving device during actual use, after power is turned on, the electromagnetic driving device pushes the movable plate 31 to move, so that the first through hole 311 of the movable plate 31 and the second through hole 331 of the fixed plate 33 are misaligned, and are separated into a first space 14 and a second space 15. At this time, the volume of the box body 1 is only the second space 15, and the volume is obviously smaller, that is, the instant heating mode, which is equivalent to reducing the volume of the box body 1, and can heat quickly and shorten the heating time.

[0036] In order to ensure that the movable plate 31 can be reset after power failure, Figure 5 As shown, a return spring 23 is installed at the end of the electromagnetic drive device, the return spring 23 is connected to the drive rod, and the other end of the drive rod is fixedly connected to the edge of the movable plate 31. After the electromagnetic drive device is started, the drive rod compresses the return spring 23. After the electromagnetic drive device is powered off, the elastic potential energy of the return spring 23 will be converted into a pulling force of the drive end 22, pulling the movable plate 31 to move backward, so that the movable plate 31 returns to its initial state. At this time, the first through hole 311 is connected with the second through hole 331, and the isolation layer in the box body 1 disappears. The first space 14 and the second space 14 in the box body 1 are connected, and water can flow from the second space 15 to the first space 14. At this time, the volume of the box body 1 is switched to the stepping mode, that is, the volume of the box body 1 is the volume of the heating water tank, which can accommodate a sufficient amount of water as set.

[0037] likeFigure 5 and Figure 6 As shown, a sealing plate 32 having a third through hole 321 is further provided between the movable plate 31 and the fixed plate 33 . The top and bottom surfaces of the sealing plate 32 are in contact with the movable plate 31 and the fixed plate 33 respectively, and the third through hole 321 is arranged to overlap with the second through hole 331 .

[0038] The top and bottom of the sealing plate 32 are transitionally connected to the movable plate 31 and the fixed plate 33 respectively, and the edges of the sealing plate 32 are respectively in contact with the inner side wall of the box body 1 and the other side of the paired convex ribs 34, namely the groove top 342. At this time, the sealing plate 32 is detachably placed in the installation space surrounded by the paired convex ribs 34 and the inner side walls of the box body 1 on the other two sides, and the sealing plate 32 and the fixed plate 33 remain stationary, which can prevent water in the first space 14 from flowing from the edge of the sealing plate 32 to the second space 15, thereby ensuring that the water flow channels in the first space 14 and the second space 15 can only flow through the first through hole 311 and the third through hole 321 and the second through hole 331. In addition, the sealing plate 32 is made of silicone rubber or nitrile rubber, which has good heat resistance and flexibility, and can prevent the fixed plate 33 and the movable plate 31 from being damaged by sliding friction between the movable plate 31 and the fixed plate 33, thereby avoiding the water separation effect of the partition component 3, thereby affecting the extension of the heating time.

[0039] like Figure 5 As shown, there are two pairs of convex ribs 34 , which are arranged opposite to each other on the inner side wall of the box body 1 and at the same height.

[0040] This can ensure that the paired ribs 34 will form a supporting effect on the movable plate 31, and at the same time ensure that the movable plate 31 can only slide along the extension direction of the ribs 34, thereby ensuring that the supporting forces of the two ribs on the movable plate 31 are equal during the sliding process of the movable plate 31, avoiding damage to the paired ribs 34 on one side due to uneven force, and the driving end 22 is connected to the center position of the long side of the movable plate 31, so that the driving force of the driving end 22 is exactly on the same line as the center of gravity of the movable plate 31, and the movable plate 31 can be made to slide horizontally with the least driving force.

[0041] like Figure 6 As shown, the horizontal cross-section of the first through hole 311 is a bar, and the movable plate 31 slides along the width direction of the first through hole 311. The shape and size of the first through hole 311 are the same as those of the second through hole 331, and the sliding distance is equal to the width of the first through hole 311.

[0042] The number of the first through holes 311 and the second through holes 331 can be equal, or they can be different. For example, the number of the first through holes 311 is twice the number of the second through holes 331. The first through holes 311 and the second through holes 331 are evenly distributed, that is, the second through holes 331 are sparsely distributed relative to the first through holes 311. When the movable plate 31 is slid, as long as the first through holes 311 partially overlap with the second through holes 331, the first space 14 and the second space 15 can be connected. At this time, the water flow rate of the communication channel between the second space 15 and the first space 14 is small; continuing to slide the movable plate 31 can make all the second through holes 331 overlap with the first through holes 311. At this time, the flow rate of water in the box body 1 can be increased, and the water inlet efficiency is improved. Since the number of the second through holes 331 is less than the number of the first through holes 311, and the distance between adjacent second through holes 331 in the sliding direction is large, the second through holes 331 and the first through holes 311 are completely overlapped, and the moving distance is large.

[0043] In order to improve the water inlet efficiency of the first space 14 and the second space 15, in this application, Figure 6 As shown, the number of first through holes 311 and second through holes 331 is equal, and the number of first through holes 311 is multiple, and the multiple first through holes 311 are evenly spaced, and the second through holes 331 are evenly spaced. In this way, the first space 14 and the second space 15 in the housing 1 can be separated. After the movable plate 31 moves a set distance, all the first through holes 311 and all the second through holes 331 are completely overlapped. At this time, each first through hole 311 is a water flow channel, that is, the communication channel between the second space 15 and the first space 14 is maximized. In other words, water added from the water inlet 11 in the second space 15 can fill the first space 14 in the shortest time, thereby ensuring that the water in the second space 15 is isolated from the water in the first space 14 during the heating process of the heating element 5. Since the capacity of the first space 14 is much greater than that of the second space 15, the heating element 5 can reach the set temperature in a shorter time when heating the second space 15, thereby improving heating efficiency.

[0044] A connecting protrusion 312 is provided on the top surface of the edge of the movable plate 31. The lower end of the connecting protrusion 312 is fixedly connected to the movable plate 31, and the upper end of the connecting protrusion 312 protrudes upward from the upper surface of the movable plate 31. The driving end 22 is connected to the connecting protrusion 312, driving the movable plate 31 to slide back and forth on the fixed plate 33.

[0045] When the cam 31 is in the unlock state, the cam 31 is in the unlock state, and the lock 31 is in the unlock state, so the cam 31 is locked.

[0046] It also includes a water level monitoring component 4, which is connected to the integrated chip signal. The water level monitoring component includes a slide rod 41, a first float 42 and a second float 43. The slide rod 41 extends along the height direction of the water tank, and the top of the slide rod 41 is fixed to the top of the box body 1. The bottom of the slide rod 41 is a free end and is arranged close to the partition component 3. Sliding holes are provided along the diameter direction of the first float 42 and the second float 43. The slide rod 41 is slidably connected to the sliding holes of the floats. The first float 42 is arranged close to the top of the slide rod 41, and the second float 43 is arranged directly below the first float 42 and close to the bottom of the slide rod 41. The driving member 2 is configured so that when the liquid level in the box body 1 drops to the position of the second float 43, the driving rod moves to drive the movable plate 31 to slide, so that the water layer in the box body 1 is divided into a first space 14 and a second space 15.

[0047] In actual use, the first float 42 and the second float 43 have cavities inside, and the side walls of the first sliding hole and the peripheral walls of the first float 42 form a sealed space. Similarly, the second sliding hole and the second float 43 also form a sealed space. The first float 42 and the second float 43 can move upward under the buoyancy of the water. When the water level drops, the first float 42 and the second float 43 will both drop due to their own gravity. Furthermore, in order to limit the range of movement of the first float 42 and the second float 43, limit snap rings 44 are provided above and below the first float 42 and the second float 43. The limit snap rings 44 are clamped on the slide rod 41, and the outer diameter of the limit snap ring 44 is larger than the inner diameter of the first sliding hole and the second sliding hole, and the limit snap ring 44 is larger than the inner diameter of the first sliding hole and the second sliding hole. There are four positioning snap rings 44, of which two positioning snap rings 44 are arranged in pairs close to the first float 42, and are respectively arranged above and below the first float 42. At this time, the positioning snap rings 44 and the top and bottom of the first float 42 have a movable gap, and the other two positioning snap rings 44 are respectively arranged above and below the second float 43, and are arranged in pairs. Similarly, the two lower positioning snap rings 44 also have a movable gap with the top and bottom of the second float 43. In addition, the gap distance between the two upper positioning snap rings 44 is equal to the gap between the two lower positioning snap rings 44. In this way, it is ensured that the first float 42 and the second float 43 both float within the set range to avoid too much or too little water in the box body 1, which affects the normal operation of the box body 1.

[0048] Before using the box 1, the water boiler program is turned on and initialized, and the automatic / manual mode is selected. The water in the box 1 is in a saturated state by default, that is, the operation mode of the box 1 is the stepping mode and the automatic mode. At this time, the water in the box 1 is within the range of the first float 42. In order to avoid the water level in the box 1 from overflowing from the box 1 due to being too high, or the water level is lower than the position of the first float 42 and there is insufficient water in the water tank, an upper limit and a lower limit are set on the first float 42. Correspondingly, the upper limit and the lower limit can be adjusted by the limit card. The first float 42 is limited by the ring 44. The upper limit of the first float 42 is the position where the first float 42 abuts against the limit snap ring 44 above the first float 42. The lower limit of the first float 42 is the position where the first float 42 abuts against the limit snap ring 44 below it. When the first float 42 reaches the lower limit of the first float 42, the integrated chip can automatically cut off the water supply, or a reminder device is installed on the upper limit snap ring 44 to send a reminder signal to the user, reminding the user to cut off the water supply in time, and at the same time, the water stored in the box 1 is heated to the preset temperature in time.

[0049] When the user uses the water boiler, the first through hole 311 and the second through hole 331 of the partition assembly 3 are in a connected state, that is, the upper first space 14 and the lower second space 15 are connected, and the water in the box body 1 flows out from the first water outlet 12, and the water level in the water tank gradually decreases until the water level drops to the lower limit of the second float ball 43. The second float ball 43 also has an upper limit and a lower limit. Correspondingly, the upper limit of the second float ball 43 is the position of the second float ball 43 abutting against the limit snap ring 44 above it, and the lower limit of the second float ball 43 is the position of the second float ball 43 abutting against the limit snap ring 44 below it. When the water level drops to the lower limit of the second float ball 43, the integrated chip sends a start signal to the driving member 2, and the driving member 2 drives the movable plate 31 to move, so that the first through hole 311 and the second through hole 331 are staggered. The water flow in the second space 15 and the first space 14 is in an interrupted state, the heating element 5 is started until the water temperature in the second space 15 reaches the set value, the water inlet solenoid valve on the water inlet 11 is opened, and the first through hole 311 and the second through hole 331 in the partition component 3 are in a connected state, the water level in the water tank gradually rises, and when the water level exceeds the second float 43, the second float 43 abuts against the limit clamp 44 near its upper part, and detects whether the water temperature sensed by the first temperature sensor 61 is lower than the set temperature value of 2°. If so, it detects whether the first float 42 reaches its upper limit, and enters the insulation state; if the temperature is higher than 2°, the water inlet solenoid valve of the water inlet 11 is opened until the water level reaches the upper limit of the first float 42, the water inlet 11 is closed, the water level in the box body 1 reaches the set upper limit range, and then enters the insulation state.

[0050] In addition, in order to improve the heating efficiency, a thermal insulation layer is provided on the side wall of the box body 1, and the thermal insulation layer covers the entire side wall of the water tank, which can form a better thermal insulation effect for the water in the water tank.
