[0002] At present, water heaters are household appliances commonly used in people's daily lives. Water heaters are divided into electric water heaters, gas water heaters, heat pump water heaters and solar water heaters. Electric water heaters are widely used because of their convenience. Among them, electric water heaters can be divided into storage electric water heaters and instant electric water heaters according to the size of heating power. Storage electric water heaters are equipped with a water tank, which has the characteristics of large water output and stable water temperature, and are purchased and used by more families.

[0003] The existing Chinese patent with application number 201721455681.6 discloses an electric water heater with a high hot water output rate, including an inner tank, a water outlet pipe, a water inlet, a water outlet and a heating pipe, the water inlet and the water outlet are respectively located on the outer surface of the inner tank, the water outlet pipe is connected to the water outlet, the heating pipe is fixed in the inner tank, the water outlet pipe and the water outlet are connected through a coil, and one end of the heating pipe extends to the coil.

[0004] The above electric water heater extends one end of the heating tube to the coil to heat the hot water in the water outlet pipe, so that the hot water flowing through the water outlet pipe is quickly heated to a specified temperature. However, since the hot water is concentrated above the inner tank, the top of the water outlet pipe is far from the top of the inner tank, and the hot water stored in the inner tank cannot be completely discharged, the hot water output rate is low, resulting in a waste of resources. In view of this, how to design a water heater technology that can discharge the hot water in the inner tank more thoroughly to improve the hot water output rate is the technical problem to be solved by the utility model. Summary of the invention

[0005] The utility model provides an inner tank component and a water heater, which can discharge the hot water in the inner tank more thoroughly to improve the hot water output rate.

[0006] In order to achieve the above technical objectives, the utility model adopts the following technical solutions:

[0007] In one aspect, the utility model provides an inner liner assembly, comprising:

[0008] An inner tank having a heating cavity formed therein;

[0009] a water inlet pipe extending into the heating inner cavity;

[0010] A water outlet pipe is extended near the top wall of the inner tank to form an extension portion, and a plurality of water inlets are provided on the extension portion, and the plurality of water inlets are distributed along the length direction of the extension portion.

[0011] In some embodiments of the present application, the free end of the extension portion is a closed structure.

[0012] By providing the end of the extension portion with a closed structure, hot water can be prevented from flowing back from the free end of the extension portion.

[0013] In some embodiments of the present application, the extension portion is parallel to the axial direction of the inner container, and there is a gap between the extension portion and the top wall of the inner container.

[0022] A fixing portion, the fixing portion being fixedly connected to the inner container;

[0023] The connecting portion is bent and connected between the extending portion and the fixing portion.

[0024] By configuring the water outlet pipe to include an extension portion, a fixing portion and a connecting portion, the extension portion is close to the top wall of the inner tank, and there is a gap between the extension portion and the top wall of the inner tank, which facilitates the extension portion to be in the hot water area of ​​the inner tank, making it convenient for hot water to enter the extension portion; the connecting portion is bent and connected between the extension portion and the fixing portion, so that the extension portion is closer to the top wall of the inner tank, so that the hot water in the inner tank is discharged through the extension portion, the connecting portion and the fixing portion in sequence.

[0025] In some embodiments of the present application, the extending portion, the fixing portion and the connecting portion are integrally formed.

[0026] By forming the extension part, the fixing part and the connecting part as one piece, the production and processing of the water outlet pipe is facilitated, which is beneficial to reducing costs and improving production efficiency.

[0027] In some embodiments of the present application, the liner includes:

[0028] barrel;

[0029] The sealing head is connected to the cylinder body and encloses the cylinder body to form the heating inner cavity; the water outlet pipe is fixedly arranged on the sealing head or the cylinder body.

[0030] By configuring the inner tank to include a cylinder body and a head, the cylinder body and the head are connected to enclose a heating cavity, and the water outlet pipe is fixedly arranged on the head or the cylinder body, water outlet from the side or from the bottom of the inner tank can be achieved, and at the same time the water outlet pipe can be kept in the hot water area of ​​the inner tank, which is conducive to maintaining the stability of the outlet water temperature.

[0031] In a second aspect, the utility model provides a water heater, comprising:

[0032] A housing having a mounting cavity formed therein;

[0033] As in any one of the embodiments of the first aspect above, the liner assembly is connected to the installation cavity.

[0051] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art may be aware of the application of other processes and / or the use of other materials.

[0052] An electric water heater uses electricity as its main energy source. The high-temperature heat generated after power is turned on directly heats the water stored in the electric water heater to prepare hot water.

[0053] An electric water heater usually includes a water tank, an electric heating component, an electric control board and other components. A water storage cavity is formed in the water tank to store the water to be heated. The electric heating component is inserted into the water storage cavity formed by the water tank. The electric control board is used to control the on and off operation of the electric heating component so that the water in the water tank is heated to a set temperature.

[0054] For the water tank of an electric water heater, the water tank generally includes an outer shell and an inner tank, and an insulation layer is formed between the outer shell and the inner tank. Among them, the outer shell is generally made of plastic material to meet the design requirements of beautiful and diverse shapes; the inner tank can be made of metal or plastic according to needs.

[0055] In addition, the insulation layer formed between the outer shell and the inner liner, commonly used insulation materials include: asbestos, sponge, foam plastic, polyurethane foam, etc. In conventional technology, in order to obtain a good insulation effect, the insulation layer is usually formed by foaming.

[0056] Among them, for the inner tank using a metal tank body, the interior of the inner tank is prone to corrosion due to the influence of water quality. For this reason, a magnesium rod is also configured on the water tank, and the magnesium rod is inserted into the water storage cavity inside the water tank.

[0057] Since magnesium is the metal with the lowest potential in the electrochemical series and is physiologically non-toxic, it is ideal for making magnesium rods to protect the inner liner. The size of the magnesium rod is directly related to the length of time the inner liner is protected and the size of the protective effect. The larger the magnesium rod, the better the protective effect and the longer the protection time.

[0058] The water tank is also provided with a water inlet pipe and a water outlet pipe. The water inlet pipe is used to transport cold water to the water storage cavity formed in the water tank, while the hot water in the water storage cavity is output from the water outlet pipe.

[0059] For the electric heating component, electric heating methods such as electric heating wire, magnetic energy or silicon tube heating can be used to heat the water stored in the water storage cavity.

[0060] As for the electric control board, it is used to receive the detection signals sent by relevant sensors (such as water temperature sensors, flow sensors), and at the same time, control the power on and off operation of the electric heating components.

[0061] When the electric water heater is working, the electric control board controls the electric heating component to be powered on for heating. When the water temperature in the water tank reaches the set value, the electric control board controls the electric heating component to be powered off.

[0062] In the first aspect, combined Figures 1 to 6 As shown, an embodiment of the present disclosure provides an inner liner assembly, which includes an inner liner 1, a water inlet pipe 2 and a water outlet pipe 3.

[0063] The inner tank assembly is used to be installed on a water heater, which can be a single tank water heater or a double tank water heater. The inner tank assembly can be used to fill the water heater with cold water or to deliver hot water to a water terminal. A connection port is formed on the inner tank 1 of the water heater, and a connection seat is provided on the inner tank assembly. The inner tank assembly extends into the heating cavity 13 through the connection port, and the connection seat is used to fix and seal the inner tank assembly and the connection port.

[0064] Application of inner tank components in single tank water heaters Figure 5 and Figure 6 As shown. Among them, Figure 5 The middle water outlet pipe 3 is in the form of discharging water from the side of the inner tank 1. Figure 6 The water is discharged from the bottom of the inner tank 1.

[0065] Application of inner tank components in double tank water heaters Figures 1 to 4 shown.

[0066] The following is an explanation using a double-tank water heater as an example. The first inner tank 11 and the second inner tank 12 of the double-tank water heater are connected by an intermediate elbow. The intermediate elbow is used to connect the first inner tank 11 and the second inner tank 12. Heaters are provided in the first inner tank 11 and the second inner tank 12. The heaters are used to heat the water in the first inner tank 11 and the second inner tank 12.

[0067] Specifically, the first inner liner 11 and the second inner liner 12 are both provided with a water inlet pipe 2 and a water outlet pipe 3, and the middle elbow specifically connects the water inlet pipe 2 in the first inner liner 11 with the water outlet pipe 3 in the second inner liner 12. The water inlet pipe in the first inner liner 11 is the same as the water inlet pipe in the second inner liner 12, and the water outlet pipe in the first inner liner 11 is the same as the water outlet pipe in the second inner liner 12.

[0068] The water outlet pipe 3 is connected to the top of the heating cavity 13 of the inner tank 1, and the water inlet pipe 2 is connected to the bottom of the heating cavity 13 of the inner tank 1, ensuring that the lower temperature water of each inner tank 1 is input to the bottom of the heating cavity 13, and the heated higher temperature water is output from the top of the heating cavity 13.

[0069] The water outlet pipe 3 is connected to a water terminal to provide hot water to the water terminal, which may be a faucet or a shower.

[0070] The water inlet pipe 2 is a side water inlet method, that is, the water inlet pipe 2 and the water outlet pipe 3 are connected to the heating cavity 13 from the end cover 15 of the inner tank 1.

[0071] It should be noted that the water outlet pipes 3 in the first inner tank 11 and the second inner tank 12 are the same, and there is no difference between the two.

[0072] The double-tank water heater includes an outer shell and an inner tank 1 arranged in the outer shell. The inner tank 1 includes a first inner tank 11 and a second inner tank 12 which are connected to each other. The first inner tank 11 is located above the second inner tank 12. A connecting portion is formed between the first inner tank 11 and the second inner tank 12.

[0073] Combination Figure 1 As shown, the water outlet pipe 3 is bent toward the top wall near the inner pot 1 and extends into the heating cavity 13. The water outlet pipe 3 extends along the top wall of the inner pot 1 to form an extension portion 31. A plurality of water inlets 311 are provided on the extension portion 31. The plurality of water inlets 311 are distributed along the length direction of the extension portion 31, and the water inlets 311 are opened upward; the free end of the extension portion 31 is a closed structure.

[0074] Specifically, by providing the inner tank 1, the water inlet pipe 2 and the water outlet pipe 3, a heating cavity 13 is formed in the inner tank 1, the water inlet pipe 2 extends into the heating cavity 13, the water outlet pipe 3 bends toward the top wall of the inner tank 1 and extends into the heating cavity 13, so that the water outlet pipe 3 is close to the hot water on the top of the inner tank 1, and the free end of the extension part 31 is a closed structure, and a plurality of water inlets 311 are provided on the extension part 31. In this way, on the one hand, the water in the water outlet pipe 3 is prevented from flowing back from the free end of the extension part 31, and on the other hand, the hot water on the top of the inner tank 1 can be discharged through the plurality of water inlets 311 on the water outlet pipe 3, so that the hot water is discharged more thoroughly, thus avoiding waste of resources and being beneficial to improving the hot water output rate.

[0075] It should be noted that the smaller the aperture of the water inlet 311, the faster the water flow rate. This is because when the water flows through a channel with a smaller aperture, the cross-sectional area of ​​the channel becomes smaller, and the volume of water flowing through per unit time is correspondingly reduced. According to the definition of flow rate, the flow rate is equal to the volume passing through per unit time divided by the cross-sectional area of ​​the channel, so the flow rate will increase. If the end of the water outlet pipe 3 is in an open state, the water with a higher flow rate in the water inlet 311 is very likely to flow back from the end of the extension part 31. By setting the free end of the extension part 31 as a closed structure, the water flow can be prevented from flowing back from the end.

[0076] In some embodiments of the present application, the aperture of the water inlet 311 is 1-5 mm.

[0077] For example, the aperture of the water inlet 311 may be 1.5 mm, 2 mm or 2.5 mm. The aperture of the water inlet 311 may be uniform or non-uniform.

[0078] In some embodiments of the present application, the number of the water inlets 311 is 2 to 20.

[0079] Exemplarily, the number of the water inlets 311 is 6. The water inlets 311 are distributed at non-equidistant intervals.

[0080] Combination Figure 2 and Figure 3 As shown, in some embodiments of the present application, the water outlet pipe 3 further includes a fixing portion 32 and a connecting portion 33 .

[0081] The extension portion 31 is close to the top wall of the inner container 1, and there is a gap between the extension portion 31 and the top wall of the inner container 1;

[0082] The fixing portion 32 is fixedly connected to the end cover 15 of the inner container 1;

[0083] The connecting portion 33 is bent and connected between the extending portion 31 and the fixing portion 32 .

[0084] Specifically, by configuring the water outlet pipe 3 to include an extension portion 31, a fixing portion 32 and a connecting portion 33, the extension portion 31 is close to the top wall of the inner tank 1, and there is a gap between the extension portion 31 and the top wall of the inner tank 1, which is conducive to the extension portion 31 being in the high-temperature hot water area of ​​the inner tank 1, and facilitating the entry of hot water into the extension portion 31; the connecting portion 33 is bent and connected between the extension portion 31 and the fixing portion 32, so that the extension portion 31 is closer to the top wall of the inner tank 1, so that the hot water in the inner tank 1 is discharged through the extension portion 31, the connecting portion 33 and the fixing portion 32 in sequence.

[0085] In some embodiments of the present application, the distance between the extension portion 31 and the top wall of the liner 1 is 2-10 mm.

[0086] Exemplarily, the distance between the extension portion 31 and the top wall of the liner 1 is 3 mm.

[0087] Exemplarily, the water outlet pipe 3 is in a Z-shape or an L-shape. Specifically, it can be arranged according to actual needs.

[0088] In some embodiments of the present application, the extension portion 31 is parallel to the axial direction of the inner container 1 .

[0089] Specifically, by arranging the extension portion 31 parallel to the axial direction of the inner tank 1, the extension portion 31 is advantageously located at the same height of the heating cavity 13. Since the temperature of the water in the heating cavity 13 at the same height is constant, it is advantageous to maintain the stability of the drainage temperature of the inner tank 1.

[0090] Combination Figure 3 and Figure 4 As shown, in some embodiments of the present application, the water inlet 311 is disposed on the extension portion 31 .

[0091] Specifically, since the extension portion 31 is close to the top wall of the inner tank 1, the extension portion 31 is higher than the fixed portion 32 and the connecting portion 33, the temperature of the water at the extension portion 31 is higher than the temperature of the water at the fixed portion 32 and the connecting portion 33. By setting the water inlet 311 at the extension portion 31, the water inlet 311 is close to the hot water area of ​​the inner tank 1, so that the hot water can be discharged from the water outlet more thoroughly, which is beneficial to improve the hot water output rate.

[0092] In some embodiments of the present application, the water inlet 311 faces the top wall of the inner container 1 .

[0093] Specifically, by setting the water inlet 311 to face the top wall of the inner tank 1, since the water temperature of the inner tank 1 rises from the bottom, the water inlet 311 faces the hot water, which facilitates the hot water to enter the water inlet 311 and allows the hot water to be discharged more thoroughly.

[0094] In some other embodiments of the present application, a plurality of water inlets 311 are arranged at intervals along the length direction of the extension portion 31 .

[0095] Specifically, by arranging a plurality of water inlets 311 at intervals, the water inlets 311 are evenly distributed along the axial direction of the inner tank 1 . The distribution area of ​​the water inlets 311 is wide, which is conducive to the complete discharge of hot water at the same height.

[0096] In some embodiments, a plurality of water inlets 311 are arranged at unequal intervals on the extension portion 31. This is because the hot water in the inner tank 1 is not evenly distributed, and more hot water is stored in the water outlet pipe 3 near the heater; accordingly, the water inlets 311 near the heater are arranged more densely, that is, the interval between the water inlets 311 is smaller; the water inlets 311 far from the heater are arranged more sparsely, that is, the interval between the water inlets 311 is larger.

[0097] In some embodiments of the present application, the plurality of water inlets 311 are arranged in a single row along the length direction of the extension portion 31 .

[0098] Specifically, by arranging the multiple water inlets 311 in a single row along the length direction of the extension portion 31 , it can be ensured that the multiple water inlets 311 are at the same height, which is conducive to maintaining the stability of the drainage temperature.

[0099] In other embodiments of the present application, the opening of the water inlet 311 is directly opposite to the top wall of the inner tank 1. The distance between the water inlet 311 and the top wall of the inner tank 1 is the smallest. Since the water temperature of the inner tank 1 rises from the bottom, the water inlet 311 faces the hot water area, which facilitates the entry of hot water into the water inlet 311, so that the hot water can be discharged more thoroughly, and the hot water on the top of the inner tank 1 can be discharged easily.

[0100] In some embodiments of the present application, the extending portion 31 , the fixing portion 32 and the connecting portion 33 are integrally formed.

[0101] Specifically, by forming the extending portion 31 , the fixing portion 32 and the connecting portion 33 as one piece, the production and manufacturing of the water outlet pipe 3 is facilitated, which is beneficial to improving the production efficiency.

[0102] In other embodiments of the present application, the inner container 1 includes a cylinder body 14 and a sealing head 15 .

[0103] The sealing head 15 is connected to the cylinder body 14 and encloses the cylinder body 14 to form a heating inner cavity 13 ; the water outlet pipe 3 is fixedly arranged on the sealing head 15 or the cylinder body 14 .

[0104] Specifically, by configuring the inner tank 1 to include a cylinder body 14 and a head 15, the cylinder body 14 and the head 15 are connected to enclose a heating cavity 13, and the water outlet pipe 3 is fixedly arranged on the head 15 or the cylinder body 14, so that the water outlet pipe 3 can be kept in the hot water area of ​​the inner tank 1, which is conducive to maintaining the stability of the outlet water temperature.

[0105] For an inner tank that outputs water from the bottom, the water outlet pipe 3 is fixed to the cylinder body 14 , and for an inner tank that outputs water from the side, the water outlet pipe 3 is fixed to the end cap 15 .

[0106] In a second aspect, an embodiment of the present disclosure provides a water heater, comprising a shell and an inner tank assembly as described in any one of the embodiments of the first aspect.

[0107] An installation cavity is formed in the shell;

[0108] The liner assembly is connected to the installation cavity. Since it includes the liner assembly of any one of the embodiments of the first aspect, it has all its beneficial effects, which will not be described in detail here.
