Description

Technical Field

[0001] The present application relates to the technical field of heating, and more specifically, to a multi-gear instant heating device and a smart toilet. Background Art

[0002] With the increasing demand for the quality of life, furniture design has gradually become intelligent. For example, a toilet is provided with various freely selectable functions, such as the hip wash / woman wash function. The hip wash / woman wash function requires about 60 ml of water to be quickly heated to a certain temperature (generally 40-50 degrees). At present, in some products on the market, an instant heater is used for heating, powered by a 220V power supply. The 220V voltage directly heats the water body, and then the water body directly flushes and cleans the human body, which has a huge potential safety hazard within a certain safety range. In another part of the products on the market, a water tank is used to store and heat the cleaning water, and when using the hip wash / woman wash function, it is mixed with cold water to a certain temperature and then sprayed for flushing. However, bacteria and molds will grow when the water tank is kept at a constant temperature.

[0003] In order to solve the problem of potential safety hazards caused by high-voltage power supply in smart toilets, there are currently products that convert the commercial power of 220V into a safe voltage of 36V. However, compared with the 220V power supply, to maintain the original heating effect with a 36V power supply, five times the current is required, which results in the need to replace the power adapter, wire, heating tube, etc. with large-current versions, increasing both the complexity and cost, and the instant heating effect is not good.

[0004] Currently, there are products that use water-absorbing and heat-generating materials for self-heating, directly heating the water by the water-absorbing and heat-generating method, avoiding the potential safety hazards brought by high-voltage heating. However, since the heat generation effect of the water-absorbing and heat-generating materials directly acts on the water, and both the water absorption and heat generation are fixed, when the input water volume is the same, the lower the temperature of the input normal-temperature water, the higher the temperature of the output water, resulting in incomplete controllability of the output water temperature and reducing the user experience.

[0005] How to design a device for controllable heating of water to maintain the user experience is a problem that needs to be solved. Utility Model Content

[0006] In view of the above problems, the present application provides a multi-gear instant heating device and a smart toilet to heat water by gears, thereby achieving controllable heating and maintaining the user experience.

[0007] To achieve the above object, the following specific solutions are proposed:

[0008] A multi-gear instant heating device includes a container, a heater with a working voltage lower than a preset voltage value, and a water outlet pipe;

[0009] The interior of the container is divided into n + 1 compartments by n baffles, where the integer n ≥ 1. Each compartment has at least one water outlet, and the water outlets of each compartment are all connected to the water outlet pipe. A valve is provided for each water outlet and each baffle.

[0010] Absorbent heat-generating materials are installed in each area, and the states of the absorbent heat-generating materials include a water-absorbing state and a water-saturated state.

[0011] The absorbent heat-generating material in the water-absorbing state is used to absorb water and generate heat when normal temperature water is input into the multi-gear instant heating device.

[0012] When the absorbent heat-generating material generates heat to the target temperature, the multi-gear instant heating device outputs cleaning water at the target temperature.

[0013] The heater is used to heat the absorbent heat-generating material in the water-saturated state, so that the water released by the absorbent heat-generating material is vaporized into water vapor, and the state of the absorbent heat-generating material is restored to the water-absorbing state.

[0014] Optionally, the heater is wrapped outside the container to heat the absorbent heat-generating material through the wall surface of the container.

[0015] Optionally, the heater is equipped with a power supply that matches it.

[0016] Optionally, the absorbent heat-generating material is molecular sieve.

[0017] Optionally, the working power of the heater is lower than the preset power.

[0018] An intelligent toilet includes the multi-gear instant heating device, a normal temperature water supply source and a cleaning nozzle as described above. The water inlet of the container for loading the absorbent heat-generating material in the multi-gear instant heating device is connected to the normal temperature water supply source, and the water outlet pipe of the multi-gear instant heating device is connected to the cleaning nozzle.

[0019] Optionally, the intelligent toilet further includes a supercharger, and the water outlet of the container is connected to the cleaning nozzle through the supercharger.

[0020] With the above technical solution, the multi-gear instant heating device of the present application includes a container, a low-pressure heater and a water outlet pipe. Multiple partitions are divided in the container by multiple baffles. Each partition has at least one water outlet, and the water outlet is connected to the water outlet pipe. All water outlets and all baffles are equipped with valves. Water-absorbing and heat-generating materials are installed in each area. When normal temperature water is input into the container, when the water-absorbing and heat-generating materials in the water-absorbing state are in the state where the corresponding valves in the target gear are open, when the normal temperature water is input into the corresponding partitions of the target gear, it absorbs water and generates heat, and the heated cleaning water is output from the water outlet of the final partition in the target gear. Finally, the heater heats the water-absorbing and heat-generating materials in the water-saturated state and restores them to the water-absorbing state. Thus, it can be seen that multiple partitions in the container can divide multiple gears. When the user selects different gears, the valve switch can control the normal temperature water to flow through different numbers of partitions, so that the heating degree is different, realizing controllable heating and maintaining the user's usage experience.

The drawings are only for the purpose of showing the preferred embodiments and are not considered to be a limitation of the present application. Moreover, throughout the drawings, the same reference numerals are used to represent the same components. In the drawings:

[0025] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0026] Figure 1 It is a schematic structural diagram of a multi-gear instant heating device provided by an embodiment of the present application, as Figure 1 shown, the multi-gear instant heating device may include: a container, a heater and a water outlet pipe.

[0027] Among them, the heater can be a low-voltage heater with an operating voltage lower than a preset voltage value. The operating power of the heater can also be lower than a preset power. The heater can be wrapped around the outside of the container to heat the water-absorbing and heat-generating material through the wall of the container.

[0028] Specifically, the heater is equipped with a matching power supply. For example, if the operating voltage of the heater is 36V, then the heater is equipped with a 36V power supply, which can convert the mains voltage of 220V into 36V.

[0029] The inside of the container is divided into n + 1 compartments by n baffles, where the integer n ≥ 1. Each compartment has at least one water outlet. The water outlets of each compartment are all connected to a water outlet pipe. Each water outlet and each baffle are equipped with valves. A water-absorbing and heat-generating material is installed in each compartment. The water-absorbing and heat-generating material can be molecular sieve, which has the property of generating heat when encountering water and can adsorb water.

[0030] As Figure 2 shown, when n = 2, there are 3 compartments in the container. In the three compartments from front to back (in the order of the normal temperature water flowing to the water outlet pipe in Figure 2 ), the water outlet of the first compartment is controlled by valve 1, the water outlet of the second compartment is controlled by valve 3, and the water outlet of the third compartment is controlled by valve 5. Since there are three compartments in the container, three heating gears can be designed. When the user needs the first gear / low gear hot water, valve 1 is opened and other valves are closed. In this state, only the water-absorbing and heat-generating material in the first compartment will come into contact with the normal temperature water, and the heat generation amount is the lowest among all gears. When the user needs the second gear / middle gear hot water, valves 2 and 3 are opened and other valves are closed. In this state, the water-absorbing and heat-generating materials in the first and second compartments will come into contact with the input municipal water. When the user needs the third gear / high gear hot water, valves 2, 4 and 5 are opened and other valves are closed. In this state, the normal temperature water will flow through the water-absorbing and heat-generating materials in the three compartments, and the normal temperature water will be heated to the maximum extent, and the heat generation amount is the highest.

[0031] Furthermore, when the number of baffles in the container is n, n + 1 heating gears can be designed. When the user needs to select the kth heating gear, the water outlet valve of the kth compartment and the valves of all baffles before the kth compartment can be opened, and at the same time other valves are closed, so that the normal temperature water flows through the water-absorbing and heat-generating materials in the first k compartments, and the normal temperature water is heated to the kth stage, realizing the k-gear heating control.

[0032] According to the water absorption degree of the water-absorbing and heat-generating material, the state of the water-absorbing and heat-generating material can be divided into several states, namely the water-absorbing state (or initial state), the water-absorption saturated state and the water-absorption unsaturated state.

[0033] Among them, the state to be water-absorbed can represent the state where the water-absorbing and heat-generating material has not absorbed water or has released all the water. The water-absorbed saturated state can represent the state where the water-absorbing and heat-generating material has completely absorbed water and cannot absorb water anymore when encountering water again. The water-absorbed unsaturated state can represent the state where the water-absorbing and heat-generating material is absorbing water but is not saturated and can still continue to absorb water.

[0034] The low-pressure and low-power heater can heat the water-absorbing and heat-generating material to cause the water-absorbing and heat-generating material to release water and return to the initial state.

[0035] Specifically, when the water-absorbing and heat-generating material absorbs water to the water-absorbed saturated state, the heater can heat the water-absorbing and heat-generating material. Specifically, the molecular sieve can be heated to 90 °C. After the molecular sieve is heated to 90 °C, it starts to release the absorbed water, and as the heating temperature rises, the released water vaporizes into water vapor, which has a disinfection effect on the energy storage type hot water filtration and heating device. At the same time, after the molecular sieve releases water, its state returns from the water-absorbed saturated state to the state to be water-absorbed, so as to carry out the next round of heat generation.

[0036] It can be understood that the purpose of the heater is to restore the initial state of the water-absorbing and heat-generating material and use the water released by the water-absorbing and heat-generating material for pasteurization. Therefore, there is no need to use a high-pressure / high-power configuration, and a low-pressure and low-power heater can meet this requirement.

[0037] Furthermore, in addition to the heating and impurity removal effects, using the molecular sieve can also remove fluorine, add hydrogen and oxygen, increase the pH value, make the cleaning water show weak alkalinity, and have stronger and healthier cleaning power.

[0038] The multi-gear instant heating device provided by the embodiment of the present application includes a container, a low-pressure heater and a water outlet pipe. The container is divided into multiple compartments by multiple baffles. Each compartment has at least one water outlet, and the water outlet is connected to the water outlet pipe. All water outlets and all baffles are equipped with valves. The water-absorbing and heat-generating material is installed in each area. When normal temperature water is input into the container, when the water-absorbing and heat-generating material in the state to be water-absorbed and the corresponding valves of the target gear are in the open state, when the normal temperature water is input into the corresponding compartments of the target gear, it absorbs heat and water, and the heated cleaning water is output from the water outlet of the final compartment of the target gear. Finally, the heater heats the water-absorbing and heat-generating material in the water-absorbed saturated state and restores it to the state to be water-absorbed. It can be seen that multiple compartments in the container can divide multiple gears, so that when the user selects different gears, the valve switch can control the normal temperature water to flow through different numbers of compartments, so that the heating degree is different, realizing controllable heating and maintaining the user's usage experience.

[0039] Based on the introduction of the foregoing multi-gear instant heating device, in some embodiments of the present application, a smart toilet is proposed. The smart toilet may include the multi-gear instant heating device, a normal temperature water supply source and a cleaning nozzle introduced in the foregoing embodiments.

[0040] As Figure 3 shown, the water inlet of the container for loading the water-absorbing and heat-generating material in the multi-gear instant heating device is connected to the normal temperature water supply source, and the water outlet pipe of the multi-gear instant heating device is connected to the cleaning nozzle.

[0041] It can be understood that in the buttock washing / feminine washing function of the intelligent toilet, a certain amount of cleaning water (40 °C to 50 °C) needs to be provided for the user. Then, normal temperature water needs to be obtained from the normal temperature water supply source. Since hot water needs to be provided to the user, the hot water can be output from the water outlet of the container to the cleaning nozzle.

[0042] Furthermore, the intelligent toilet may further include a supercharger. As Figure 3 shown, the water outlet of the container can be connected to the cleaning nozzle through the supercharger to pressurize the output hot water flow, which can ensure the flushing force during buttock washing / feminine washing.

[0043] Next, an application example of the buttock washing / feminine washing function of the intelligent toilet will be introduced. Specifically, it may include the following steps:

[0044] S1. Calculate and obtain the required normal temperature water and the heating target gear according to the cleaning water demand of the buttock washing / feminine washing function of the intelligent toilet.

[0045] Specifically, in the automatic setting mode of the buttock washing / feminine washing function of the intelligent toilet, the temperature of the municipal normal temperature water can be obtained through the temperature sensor, and according to the user's water consumption demand, the heating target gear and the normal temperature water volume required to reach the target temperature (40 to 50 degrees Celsius) can be calculated.

[0046] In addition, the buttock washing / feminine washing function of the intelligent toilet can also provide a manual setting mode, and the user can set the heating gear through a button knob or the like.

[0047] S2. Extract the required normal temperature water from the normal temperature water supply source.

[0048] S3. Inject the normal temperature water into the multi-gear instant heating device, so that the normal temperature water flows through the water-absorbing and heat-generating materials of each layer corresponding to the heating target gear, and the water-absorbing and heat-generating materials generate heat by themselves to heat the normal temperature water to obtain hot water.

[0049] S4. The hot water outputs the heated hot water through the water outlet of the final layer corresponding to the heating target gear.

[0050] S5. The hot water is transported to the water outlet pipe through the water outlet, and then transported to the cleaning nozzle, and the user uses the hot water through the cleaning nozzle.

[0051] S6. After completing one buttock washing / feminine washing function, the low-voltage and low-power heater heats the water-absorbing and heat-generating materials, releases moisture, and vaporizes it into water vapor to perform pasteurization on the multi-gear instant heating device.

[0052] It can be seen that the heating process of the flushing water body for the hip washing / feminine washing function of the intelligent toilet is in a no-current or low-current mode, which is extremely safe during use and solves the safety hazards brought by high-voltage heating. At the same time, there are multiple compartments in the container of the multi-gear instant heating device to achieve multi-gear heating control, ensuring the user experience of using hot water.
