Embodiment 1

[0035] Such as image 3 , Figure 4 As shown, an electric water heater with a high hot water output rate includes: a housing 1, an inner tank 2, a water inlet pipe 5 installed on the inner tank 2, a water outlet pipe 6, a magnesium rod assembly 8 and a heating device; it is characterized in that A water mixing device 10 is installed in the lower space of the inner tank 2, the water inlet pipe 5 and the water outlet pipe 6 are connected to the water mixing device 10, and several The water inlet hole is provided with a water mixing hole communicated with the water mixing device 10 on the water outlet pipe 6. After the water in the water inlet pipe 5 enters the water mixing device 10, a part passes through the water inlet hole Enter the inner tank 2, and the other part enters the outlet pipe 6 through the mixing hole 11.

[0036] Wherein, both the water inlet pipe 5 and the water outlet pipe 6 pass through the water mixing device 10 and are sealed and connected to the inner tan...

Embodiment 2

[0044] Such as Figure 7 , Figure 8 As shown, the electric water heater with high hot water output rate provided by this embodiment is basically the same in structure as that of Embodiment 1, the difference lies in:

[0045] 1. A water proportional valve 13 is provided at the water inlet ends of the first area 11 and the second area 12 , and the amount of water entering the first area 11 and the second area 12 is controlled by the water proportional valve 13 . The water proportional valve 13 is connected with the main controller 14 of the electric water heater, and adjusts the water volume according to the instructions issued by the main controller 14 . Referring to Embodiment 1, the main controller 14 of the electric water heater can also collect the temperature of the outlet water through a temperature sensor as a basis for adjustment.

[0046] 2. The water inlet pipe 5 is divided into left and right parts, the water flow of the left part flows directly into the area 2 12...

Embodiment 3

[0050] A method for increasing the hot water output rate of an electric water heater, which is characterized in that the incoming water flow entering the bottom layer of the inner tank of the electric water heater is divided into two parts, one part enters the inner tank, is heated by a heater in the inner tank, and flows from the top of the water outlet pipe Into the outlet pipe, the other part enters the outlet pipe from the bottom of the outlet pipe after being preheated by the bottom water of the liner. In this way, on the premise of ensuring that the water inlet flow rate is not reduced and the water outlet flow rate is sufficiently large, useless mixing of cold and heat is reduced, the hot water output rate is increased, and energy is saved. At the same time, it has its own mixing valve effect, and there is no need for an external mixing valve.

Abstract

The invention discloses an electric water heater with high hot water output rate. The electric water heater comprises an inner container, a water inlet pipe, a water outlet pipe, a magnesium rod assembly and a heating device, wherein the water inlet pipe, the water outlet pipe, the magnesium rod assembly and the heating device are installed on the inner container. The electric water heater is characterized in that a water mixing device is installed in a lower space of the inner container, the water inlet pipe and the water outlet pipe are both connected with the water mixing device, a plurality of water inlet holes are formed in the water mixing device, a water mixing hole communicating with the water mixing device is formed in the water outlet pipe, after water in the water inlet pipe enters the water mixing device, part of the water enters the inner container through the water inlet holes, and the other part of the water enters the water outlet pipe through the water mixing hole. Onthe premise of ensuring that the water inlet flow rate is not reduced and the water outlet flow rate is large enough, the electric water heater reduces useless cold and hot mixing, the hot water output rate is improved, and energy is saved; and the effect of a water mixing valve is achieved, and the water mixing valve is not required for being connected in an external mode. The invention further provides a method for improving the hot water output rate of the electric water heater.

Description

technical field [0001] The invention relates to the technical field of water heaters, in particular to an electric water heater with a high hot water output rate and a method for increasing the hot water output rate. Background technique [0002] The existing electric water heater generally adopts the water inlet method of low inflow and high outflow in order to increase the hot water output rate. At the same time, the electric water heater is generally installed with a water retaining structure, such as figure 1 As shown, the water inlet method of the existing electric water heater is as follows figure 2 shown. Because the density of water becomes smaller as the temperature rises, the density of hot water is smaller than that of cold water. Therefore, the upper layer of the inner tank is the hot water layer, and the lower layer is the cold water layer, so the water in and out method with low inflow and high outflow is the best method for all storage water heaters. common...
