Description

Technical Field

[0001] The invention relates to the field of water heaters, and in particular to a docking type open water heater capable of storing water. Background Art

[0002] Traditional water heaters are mainly divided into storage water heaters and instant water heaters. Storage water heaters are the most widely used type of water heaters, but traditional open storage water heaters have been eliminated due to troublesome installation and inconvenient use. At present, most of the storage water heaters on the market are closed, and their internal volume is in a closed state. After heating, the internal pressure increases, and the inner tank needs to withstand the pressure. A sturdy barrel-shaped corrosion-resistant inner tank and a special pressure relief device must be used to prevent the risk of explosion. In addition, due to the large size, it is more troublesome to install, and it requires special personnel to install, which increases the customer's cost of use. Instant water heaters are emerging water heaters on the market. They are small in size, heat up quickly, and are very convenient to heat hot water immediately. However, their power is too large, the requirements for the line are high, and the water pressure cannot be too high, otherwise the hot water temperature cannot be raised and cannot be used comfortably. Therefore, many user families cannot install and use them, and the application scenarios are limited.

[0003] In addition, the instant water heaters on the market are also available in docking type. Although the installation is convenient, because the entire heater needs to be hung on the original faucet, the connection between the faucet and the docking instant water heater is under too much force, and it is easy to fall off due to excessive water pressure. In addition, the heater is too close to the water outlet, which makes customers worry about safety issues.

[0004] The present invention is dedicated to proposing a water heater solution that can solve the above problems. It not only has the advantages of traditional storage water heaters and instant water heaters, but also avoids the disadvantages of the two water heaters. It also has the characteristics of low cost, portability, ease of use and installation. Summary of the invention

[0005] The purpose of the present invention is to provide a docking type water storage open water heater, whose heating module is located in the water storage tank, and can be quickly installed on an ordinary faucet through a small-volume docking head. Cold water flows from the faucet into the docking head, enters the water storage tank through a water pipe, and flows back to the docking head through another water pipe after being heated by the heating module, and can be mixed with the cold water in the faucet in any proportion to form warm water and then flow out from the water outlet on the docking head. The water heater has the advantages of both traditional water storage water heaters and instant water heaters, and can avoid the disadvantages of the two water heaters, and also has the characteristics of low cost, portability, ease of use and installation.

[0006] In order to achieve the above object, the technical solution of the present invention is as follows:

[0007] A docking type water storage open water heater comprises a docking head, a water mixing valve, a first water pipe, a second water pipe, a water storage tank, and a heating unit.

[0008] The connecting head is provided with a water inlet end and a water outlet end.

[0009] The water mixing valve is installed in the connection head, and includes a water diversion inlet, a first water diversion outlet, a second water diversion outlet, and an adjusting end. The water flowing from the water diversion inlet can be adjusted to flow to the first water diversion outlet and the second water diversion outlet at a ratio through the adjusting end of the water mixing valve.

[0010] The water storage tank is provided with a water tank inlet and a water tank outlet.

[0011] The water inlet end of the connector is connected to the external water supply port, the water diversion inlet of the water mixing valve is connected to the water inlet end of the connector, one end of the first water pipe is connected to the first water diversion outlet, and the other end is connected to the water inlet of the water tank, one end of the second water pipe is connected to the water outlet of the water tank, and the other end is connected to the water outlet end of the connector, and the second water diversion outlet of the water mixing valve is also connected to the water outlet end of the connector.

[0012] The heating unit is used to heat the water in the water storage tank.

[0013] In some embodiments of the present invention, the external water supply port is a tap, and the water inlet end of the connecting head is fixedly mounted on the tap.

[0014] Preferably, the heating pipe of the heating unit is arranged near the water outlet of the water tank. The advantage of arranging the heating pipe near the water outlet of the water tank is that the heated water can flow to the water outlet of the connector immediately, thereby improving the heating efficiency and the speed at which the connector outputs hot water.

[0015] Preferably, the water tank outlet is located at the upper part of the water tank, and the water tank inlet is located at the lower part of the water tank. Since the present invention is an open water storage tank design, the water tank outlet is directly connected to the water outlet end of the connector, so arranging the water tank outlet at the upper part of the water tank is conducive to preventing water leakage.

[0016] Preferably, the water tank inlet and the water tank outlet are both located at the upper part of the water tank. The water tank inlet is set at the upper part or the lower part of the water storage tank, which is a common choice for traditional water heaters and has its own advantages and disadvantages. If both are set at the upper part, the water inlet pipe and the water outlet pipe can be bundled together, which improves the simplicity of the product and does not need to worry about water leakage at the water tank inlet. However, there will also be a water return problem that the heated water flows back to the cold water area near the water tank inlet instead of directly flowing to the water outlet end of the connector, which affects the heat utilization rate and the speed at which the connector outputs hot water. In the case where both the water tank inlet and the water tank outlet are arranged at the upper part of the water tank, in order to solve the above-mentioned backflow problem, preferably, an isolation plate is also arranged in the water tank, and the isolation plate divides the upper volume of the water tank into two parts, namely, the first water tank part and the second water tank part. The lower volume of the water tank is connected, the water tank inlet is located above the area where the first water tank part is located, the water tank outlet is located above the area where the second water tank part is located, and the heating pipe of the heating unit is arranged in the second water tank part. In this case, after the cold water enters the water tank inlet, it needs to flow through the first water tank part first, then bypass the lower part of the water tank and enter the second water tank part, reach the position of the heating pipe and then be heated. This design effectively solves the backflow problem, and when the volume of the second water tank part is set small enough, it is possible to quickly heat the water in the second water tank part, thereby achieving the instant heating effect of the instant faucet. In addition, this design does not need to worry about not being able to heat the water in the entire water tank, because the isolation plate only affects the water flow and heat exchange efficiency between the two water tank parts but does not block it. If heated for a long time, the water and heat in the second water tank part will still be transferred to the first water tank part, thereby achieving the effect of heating the water in the entire water tank.

[0017] Furthermore, it also includes an adjusting knob, which is installed on the connecting head and cooperates with the adjusting end of the water mixing valve. Turning the adjusting knob can drive the adjusting end to rotate. The setting of the adjusting knob is mainly to facilitate the user to adjust the water temperature of the water outlet end of the connecting head at any time, so that it can only output hot water or only output cold water or output warm water mixed with hot water and cold water in any proportion.

[0018] Preferably, the first water pipe and the second water pipe are bundled together in parallel. This design is mainly to improve the simplicity and aesthetics of the product.

[0019] Preferably, the water outlet of the connector is provided with a water pipe quick connector for connecting with an external accessory. The water pipe quick connector may be a common water pipe interface such as a threaded interface. The external accessory may be a shower head for bathing, a dishwashing head for washing dishes, or other commonly used water outlet accessories in the kitchen and bathroom.

[0020] Furthermore, the present invention also includes a water temperature detection and display module for displaying the water temperature in the water tank or at the water outlet of the connector, so that the user can understand the current water temperature.

[0021] Furthermore, the present invention also includes a handle installed on the water tank housing, and the handle is used to facilitate the movement of the water tank, thereby improving the portability and mobility of the present invention.

[0022] Beneficial effects of the present invention:

[0023] (1) The present invention has the advantages of both the traditional storage water heater that can store hot water and the instantaneous faucet that can be quickly installed and heated immediately, and can meet various water needs in the kitchen, bathing, etc.;

[0024] (2) Since the water inlet and outlet of the present invention are both arranged on a compact connector, the connector will not occupy too much space under the faucet after being installed on the faucet. Taking the kitchen usage scenario as an example, there is usually a sink under the faucet, and the distance between the faucet and the sink is designed to have a slight surplus for daily use. If the installed water-boiling device is too large, it will take up a lot of space, resulting in the inability to put basins, pots, buckets and other utensils used in daily life into the sink to collect water. The connector of the present invention is compact and this problem basically does not exist;

[0025] (3) The water-mixing design on the connector meets the needs of users to use hot water, warm water, or cold water at will, and no matter whether it is hot water, cold water, or warm water, it flows out from the same outlet, i.e., the outlet end of the connector;

[0026] (4) The water tank of the present invention adopts an open design, and the water outlet of the water tank is directly connected to the water outlet end of the connector, that is, connected to the atmosphere. There is no risk of explosion due to excessive internal pressure after the water tank is boiled. Therefore, it is not necessary to use a strong inner tank and a pressure relief device, which greatly reduces its manufacturing cost compared with traditional water heaters.

[0027] (5) The water outlet of the connector can be connected to accessories such as shower heads and dishwashers through a quick-connect water pipe, which greatly enriches its usage scenarios;

[0028] (6) Portable, movable, easy to install and very convenient to use.

[0029] It should be noted that the beneficial effects of the present invention are not limited to the above six items, and the beneficial effects can be understood in conjunction with specific technical solutions. In addition, descriptions of the technical effects and beneficial effects of a specific technical solution are also interspersed in the content of the present invention and the implementation methods described below.
