Description

Technical Field

[0001] The utility model belongs to the technical field of water heaters, and particularly relates to a vertical water heater water tank with an inlet liner and a vertical heat pump water heater. Background Art

[0002] In modern life, vertical water heaters bring us comfort and convenience. One of the reasons why vertical water heaters are most favored by consumers is their high efficiency and energy saving characteristics.

[0003] Compared with traditional water heaters, vertical water heaters adopt advanced heat preservation technology, which can effectively retain the hot water temperature and reduce energy consumption. In the current situation of enhanced environmental awareness, it can also help us reduce energy costs and carbon emissions, meeting the trend of sustainable development. In terms of space utilization, vertical water heaters are also extremely excellent. With comprehensive and high-quality performance, vertical water heaters bring us a comfortable, safe and energy-saving experience, becoming a good helper for modern family life.

[0004] For example, there is an obvious water temperature stratification phenomenon in the vertical water tank of a vertical heat pump water heater. Since the density of water changes with temperature, an increase in temperature will cause the water density to decrease, and the density of cold water is greater than that of hot water. During the heating process of the water tank, the water temperature stratification phenomenon is usually more significant.

[0005] In the initial stage of heating, the heating will cause the overall temperature of the water body in the water tank to rise. However, as the heating time progresses, since the heating source is usually located at the bottom or side of the water tank, the heating will cause the temperature at the bottom and side of the water tank to rise, the density to decrease and rise, forming a hot zone. The low-temperature water sinks due to its larger density, resulting in an obvious water temperature stratification phenomenon in the water heater water tank.

[0006] In the existing water tank, during the process of the user discharging water, due to a certain water pressure at the water tank inlet, it will cause obvious convection and disturbance between the cold water entering the water tank and the hot water already in the water tank, affecting the water temperature stratification phenomenon in the water tank.

[0007] Therefore, designing a vertical water heater water tank that can reduce the flow rate of cold water after entering the water tank, maintain the stratification effect of cold and hot water in the water tank, and avoid sudden cold and hot water output has become a technical problem that needs to be solved urgently by those skilled in the art.

[0038] To make the purposes, technical solutions and advantages of the embodiments of the utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments with reference to the accompanying drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0040] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installed", "connected", "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0041] An embodiment of the present utility model discloses a vertical water heater tank with an inlet liner, which is applied to water heater equipment, and mainly applied to vertical heat pump water heaters. Of course, the water heater can also be any type and any model of solar water heater, gas water heater, and electric water heater; the water tank of the water heater can be vertical or horizontal.

[0042] In this embodiment, the vertical heat pump water heater is provided with an inlet, and the water inlet pipe for supplying water to the vertical water tank is connected to the inlet liner 1 through the inlet on the water tank; the inlet liner 1 can be fixed on the inlet of the water tank, one end is connected to the water inlet pipe, and the other end is located inside the water tank; of course, any connection method can be set between the inlet and the water tank; under the condition of ensuring the sealing performance, the cold water flowing through the inlet enters the water tank through the inlet liner.

[0043] Moreover, the water outlet end of the inlet liner 1 is the water outlet hole 3 provided on its peripheral wall 2, and the water inlet pipe enters the water tank through the water outlet hole 3 of the inlet liner 1, which is used to stabilize the stratification phenomenon of cold and hot water in the vertical water tank of the water heater and can solve the problem of sudden cold and sudden hot water outlet of the existing water heater water tank. On the one hand, it improves the utilization efficiency of hot water and realizes energy conservation; on the other hand, it enhances the user experience of using the water heater.

[0044] As Figures 1 to 5 shown, in an embodiment of the present utility model, the vertical heat pump water heater transfers the heat in the low-temperature heat source to the water inside the vertical water tank through components such as a compressor, an evaporator, a condenser, and an expansion valve in the heat pump circulation system, thereby heating the water; the heat pump is arranged at a position close to the vertical water tank, at the bottom or side of the vertical water tank, which can reduce the loss of heat transfer.

[0045] The vertical water tank is provided with a water inlet and a water outlet. Cold water enters the water tank through the water inlet communicated with the water inlet pipe, and a heat pump arranged at the bottom or side of the water tank heats the water. In the initial stage of heating, the heating causes the overall temperature of the water body in the water tank to rise. However, as the heating time progresses, the heating causes the water temperature at the bottom and sides of the water tank to rise, resulting in a decrease in density and an upward movement, forming a hot water area in the upper part of the water tank. The low-temperature water sinks due to its relatively large density, forming a cold water area in the lower part of the water tank, resulting in an obvious stratification phenomenon of the water temperature in the water heater water tank.

[0046] In this embodiment, the water inlet and the water outlet are arranged on the side of the vertical water tank; the water inlet is arranged near the bottom of the vertical water tank, and cold water enters the cold water area in the water tank from the water inlet; the water outlet is arranged near the top of the vertical water tank, and the hot water in the hot water area flows from the water outlet into the water outlet pipe to provide domestic hot water for users.

[0047] In some specific embodiments, the water inlet and the water outlet are usually arranged on the same side of the vertical water tank; sometimes, due to the limitation of the installation space of the water heater, they may also be arranged on different sides of the vertical water tank.

[0048] As Figures 1 to 5 shown, in this embodiment, the water tank of the water heater is a cylindrical vertical water tank, which is vertically installed on the wall or in the corner; the water inlet of the vertical water tank is communicated with the water inlet liner 1, and water enters the water tank through the water outlet holes 3 arranged on the water inlet liner 1. Of course, in this embodiment, it is not limited to only including one water inlet liner 1, and there can also be other schemes such as being connected through multiple water inlet liners 1, which will not be listed one by one here. Only the above-mentioned attached drawings are used as examples for elaboration:

[0049] As Figure 1 shown, in the embodiment of the present utility model, a water inlet liner 1 is arranged at the water outlet end of the water inlet pipe, and the water inlet pipe is communicated with the inside of the water tank through the water inlet liner 1 for supplying water to the inside of the water tank.

[0050] Specifically, in the embodiment of the present utility model, the water inlet liner 1 is in the shape of a circular straight cylinder. One end of the circular straight cylinder-shaped water inlet liner 1 is fixed on the water inlet, and the other end extends towards the middle of the water tank, and the extended end just passes through the axis of the water tank, and the extended end is a closed end 4; the water outlet holes 3 of the water inlet liner 1 are arranged on the peripheral wall 2 on the side close to the closed end 4.

[0051] Preferably, the closed end 4 protrudes outwards in an arc shape along the axial direction of the water inlet liner 1; when the water flow reaches the inside of the water inlet liner 1, the closed end 4 of the water inlet liner 1 will be impacted by the water flow. By setting the arc-shaped closed end 4, the stress between the closed end 4 and the peripheral wall 2 can be changed, increasing the connection strength between the closed end 4 of the water inlet liner and the closed end 4 and the peripheral wall 2, further improving the impact resistance of the water inlet liner 1 and extending the service life of the water inlet liner 1.

[0052] In some possible embodiments, the closed end 4 may further be provided with a drain hole. There may be one drain hole, or a plurality of drain holes may be provided according to specific circumstances. The hole opening diameter of the drain hole is smaller than the hole opening diameter of the water outlet hole 3, which can change the stress of the closed end 4, further increase the strength of the closed end 4, and at the same time increase a certain amount of water output without affecting the water flow velocity.

[0053] As Figures 2 to 4 shown, in the embodiment of the present utility model, the water outlet hole 3 is the water outlet end of the inlet liner 1. There are a plurality of water outlet holes 3, all of which are circular through holes, arranged on the downstream side close to the direction of water flow inside the inlet liner 1, and the openings face the bottom side of the water tank. The water flows out through the water outlet hole 3 and enters the water tank.

[0054] Specifically, in the embodiment of the present utility model, the plurality of water outlet holes 3 are arranged along the axial direction of the inlet liner 1, and are concentrated on the circumferential wall 2 at a position close to the axis of the water tank, so that the water outlet position of the cold water is concentrated in the middle of the water tank, controlling the position of the water flow and avoiding large fluctuations in the water flow, which may affect the stratification.

[0055] As Figures 2 to 5 shown, in the embodiment of the present utility model, there are two groups of the plurality of water outlet holes 3, and each group includes the same number of a plurality of water outlet holes 3, and they are symmetrically arranged with respect to the axis of the circumferential wall 2.

[0056] Specifically, in this embodiment, the two groups of water outlet holes 3 are arranged at intervals along the circumferential direction of the inlet liner 1; preferably, the axes of the two groups of water outlet holes 3 arranged corresponding to each other along the circumferential direction of the inlet liner 1 are perpendicular to each other, and the arrangement intervals between adjacent two water outlet holes 3 in each group are the same.

[0057] Preferably, the two groups of water outlet holes 3 correspond to each other one by one along the circumferential direction of the inlet liner 1, or are staggered with each other.

[0058] More specifically, in the embodiment of the present utility model, the openings of one group of water outlet holes 3 face obliquely downward, and the angle with the horizontal direction is 45 degrees; the openings of the other group of water outlet holes 3 are arranged to face obliquely downward, and the angle with the horizontal direction is 135 degrees.

[0059] The water flows through the two groups of water outlet holes 3 and flows obliquely downward into the water tank in the directions of 45 degrees and 135 degrees with the bottom of the water tank respectively. It can control the flow direction of the cold water entering the water tank while ensuring the water inflow of the water tank, reduce the flow velocity of the cold water entering the water tank; thereby avoiding the stirring and disturbance of the hot water in the water tank by the cold water entering the water tank, and well stabilizing the stratification phenomenon of the cold and hot water in the vertical water tank; it can also improve the utilization efficiency of the hot water and achieve resource conservation.

[0060] Preferably, the axis of the water inlet liner 1 is perpendicular to the axis of the water tank, which can ensure the orientation of the water outlet holes 3, and thus ensure the direction of cold water flowing into the water tank.

[0061] In some specific embodiments, the specific number, arrangement manner, etc. of the water outlet holes 3 can be adaptively adjusted according to the size of the water heater water tank set; for example, when the water tank capacity is large, in order to ensure the water inflow volume of the water tank, the number of the water outlet holes 3 is appropriately increased; when the water tank capacity is small, the number of the water outlet holes 3 is appropriately reduced to avoid affecting the effect of stably separating cold and hot water when the water inlet liner 1 intakes water into the water tank; also for example, when the shape of the water heater water tank is irregular, the number of each group of water outlet holes 3 can be adjusted according to the specific shape, and the number of each group of water outlet holes 3 may not be equal.

[0062] Such as Figure 5 As shown, in the embodiment of the present utility model, the water inlet liner 1 is a straight pipe, including a straight pipe main body 6 and a rubber plug 5; the rubber plug 5 is arranged at one end of the water inlet liner 1 connected to the water inlet, and is arranged on the peripheral wall 2 of the straight pipe main body 6; at least part of the rubber plug 5 is inserted into the water inlet of the water tank and is elastically squeezed and connected with the water inlet.

[0063] Specifically, in the embodiment of the present utility model, the inner peripheral wall of the rubber plug 5 and the outer peripheral wall of the straight pipe main body 6 are elastically squeezed and matched to be mutually sealed; the outer peripheral wall of the rubber plug 5 and the inner peripheral wall of the water inlet are elastically squeezed and matched.

[0064] Specifically, in the embodiment of the present utility model, the rubber plug 5 is an insulating rubber plug 5, and the insulating rubber plug 5 further includes a radial protrusion 7 arranged on its outer peripheral wall, which is used to maintain the sealing effect at the elastic squeezing connection between the water inlet liner 1 and the water inlet and avoid water leakage at the connection; the insulating property of the insulating rubber plug 5 can prevent the conduction of current or heat and improve the safety of the water heater equipment.

[0065] In the embodiment of the present utility model, an installation groove is further arranged on the side wall of the water tank, the water inlet is opened at the bottom of the installation groove, the inner diameter of the water inlet is smaller than the inner diameter of the installation groove, the radial protrusion 7 is embedded in the installation groove, and a circumferential positioning structure is arranged between the radial protrusion 7 and the side wall of the water tank.

[0066] Specifically, in the embodiment of the present utility model, the circumferential positioning structure includes a clamping groove 8 and a clamping protrusion arranged at the notch of the radial protrusion 7 and the installation groove; the clamping groove 8 is arranged on the radial protrusion 7 and close to the side wall of the water tank; the clamping protrusion is arranged on the side wall of the water tank, and the clamping protrusion is clamped in the clamping groove 8 to realize the circumferential positioning between the water tank and the water inlet liner 1, ensure the installation angle of the water inlet liner 1, and enable the water outlet holes 3 to be installed at a set angle. In this embodiment, the above set angle specifically refers to that the axis of one group of water outlet holes 3 forms a 45° angle with the bottom of the water tank, and the axis of the other group of water outlet holes 3 forms a 135° angle with the bottom of the water tank.

[0067] In this embodiment, at least a plurality of card slots 8 are arranged at circumferential intervals along the radial protrusion 7. Moreover, the model and / or shape of at least one card slot 8 is different from the model and / or shape of other card slots 8. The shape of the card protrusion corresponds to and fits the shape of the card slot, so as to realize the installation of the water inlet liner at a fixed angle.

[0068] In some specific embodiments, the card slots 8 can be set to four, and of course, they can also be set to three, or two. In this embodiment, taking the case of setting four card slots as an example for illustration.

[0069] In this embodiment, the four card slots 8 are respectively arranged at the uppermost, lowermost, leftmost, and rightmost positions of the radial protrusion 7, and the openings of the card slots 8 are all arranged on the side away from the axis of the water inlet liner 1 and close to the side wall of the water tank; the shape of the card slot 8 arranged at the lowermost position fits the shape of the card protrusion arranged at the lowermost position and cooperating with this card slot 8.

[0070] Specifically, in the embodiment of the present utility model, the structures of the three card slots 8 arranged at the uppermost, leftmost, and rightmost positions are the same; the inner walls of the three card slots 8 on the side close to the axis direction of the water inlet liner 1 extend radially along the water inlet liner 1, and the thickness of the extension to the inner wall of the card slot 8 and the inner peripheral wall of the water inlet liner 1 is slightly less than the thickness between the outer peripheral wall of the rubber plug 5 and the inner peripheral wall of the water inlet liner 1, so that the card protrusions with matching shapes can be inserted into the card slots 8; the inner wall of the lowermost card slot 8 on the side close to the axis direction of the water inlet liner 1 extends radially along the water inlet liner 1, and the thickness of the extension to the inner wall of this card slot 8 and the inner peripheral wall of the water inlet liner 1 is slightly greater than the thickness between the outer peripheral wall of the rubber plug 5 and the inner peripheral wall of the water inlet liner 1.

[0071] Preferably, in some possible embodiments, the card slots 8 can also be arranged on the side wall of the water tank, and the card protrusions are arranged on the radial protrusion 7, so that the card protrusions with matching shapes are engaged with the card slots 8, and the fixed-angle installation of the water inlet liner 1 can be realized.

[0072] More specifically, in this embodiment, the end face of the radial protrusion 7 abuts against the side wall of the water tank on the outer periphery of the water inlet, further enhancing the sealing performance.

[0074] During the process of the user draining water, the water inlet of the water tank enters the interior of the water tank through the water inlet liner 1, reducing the water pressure of the cold water entering the cold area, avoiding obvious convection and disturbance between the cold water entering the water tank and the hot water already in the water tank, and affecting the temperature stratification phenomenon in the water tank. At the same time, it can also set water outlet holes on the peripheral wall 2 with angles of 45 degrees and 135 degrees with the bottom of the water tank, discharging water in the directions of 45 degrees and 135 degrees with the bottom of the water tank, controlling the water flow direction and velocity, avoiding violent fluctuations in water temperature, maintaining the stratification effect of cold and hot water in the water tank, and enhancing the user experience.
